WEBVTT 00:00:00.000 --> 00:00:02.200 Welcome back to the deep dive. This is where 00:00:02.200 --> 00:00:04.480 we grab that overwhelming stack of information 00:00:04.480 --> 00:00:07.839 on a really complex topic. And while we distill 00:00:07.839 --> 00:00:10.400 it down, we give you the essential nuggets of 00:00:10.400 --> 00:00:12.939 insight, making you the most informed person 00:00:12.939 --> 00:00:15.539 in the room quickly and thoroughly. And today 00:00:15.539 --> 00:00:18.440 we are undertaking a deep dive into something 00:00:18.440 --> 00:00:21.940 that. I mean, it literally defines the relationship 00:00:21.940 --> 00:00:25.300 between citizens and their governments. Yeah. 00:00:25.379 --> 00:00:27.500 Income tax. Right. It's an essential, almost 00:00:27.500 --> 00:00:30.480 universal mechanism. But the history behind it, 00:00:30.539 --> 00:00:34.159 the, you know, the complex mechanics and the 00:00:34.159 --> 00:00:37.039 economic consequences are just profoundly misunderstood. 00:00:37.399 --> 00:00:39.259 Exactly. We all interact with it. I mean, you 00:00:39.259 --> 00:00:41.500 see it on your pay stub. You file a return. But 00:00:41.500 --> 00:00:44.240 how many of us genuinely understand why the systems 00:00:44.240 --> 00:00:45.939 are built the way they are? Right. Why are my 00:00:45.939 --> 00:00:48.119 wages taxed differently than, say, my investment 00:00:48.119 --> 00:00:50.549 returns? Why would a country even try to chase 00:00:50.549 --> 00:00:52.590 income all over the globe? Our source material 00:00:52.590 --> 00:00:55.289 for this is pretty ambitious. It gives us a really 00:00:55.289 --> 00:00:57.570 structured, comprehensive overview. It traces 00:00:57.570 --> 00:01:00.390 income tax from its earliest and sometimes shockingly 00:01:00.390 --> 00:01:03.509 modern sounding precursors right up to the policy 00:01:03.509 --> 00:01:05.409 dilemmas we face today. Things like international 00:01:05.409 --> 00:01:08.409 tax competition or bracket creep. Bracket creep, 00:01:08.549 --> 00:01:10.510 the never ending battle against avoidance, all 00:01:10.510 --> 00:01:13.409 of it. So our mission today is to give you the 00:01:13.409 --> 00:01:16.829 framework to understand not just your own tax 00:01:16.829 --> 00:01:19.629 situation, but the whole global architecture 00:01:19.629 --> 00:01:22.170 that governs how governments finance pretty much 00:01:22.170 --> 00:01:24.590 everything they do. Let's start with the basics. 00:01:24.750 --> 00:01:26.950 What are we actually talking about here? At the 00:01:26.950 --> 00:01:30.430 highest level, income tax is just a levy. It's 00:01:30.430 --> 00:01:33.359 imposed on a taxpayer. That could be an individual 00:01:33.359 --> 00:01:36.519 or an entity based on their specific calculated 00:01:36.519 --> 00:01:39.939 income or profits. And we call that taxable income. 00:01:40.099 --> 00:01:42.319 We call that taxable income. And the fundamental 00:01:42.319 --> 00:01:45.500 calculation is, you know, it's very simple. The 00:01:45.500 --> 00:01:48.719 tax rate multiplied by that taxable income. That 00:01:48.719 --> 00:01:51.400 equals the amount you owe. That sounds deceptively 00:01:51.400 --> 00:01:54.120 elegant. It is. And yet that simple equation 00:01:54.120 --> 00:01:56.480 somehow generates tax codes that are thousands 00:01:56.480 --> 00:01:58.900 of pages long. Because the devil is entirely 00:01:58.900 --> 00:02:02.109 in the definitions. It all comes down to the 00:02:02.109 --> 00:02:04.810 complex, sometimes, frankly, arbitrary determination 00:02:04.810 --> 00:02:07.790 of what counts as taxable income, how you apply 00:02:07.790 --> 00:02:10.689 the right rate. And those definitions. They determine 00:02:10.689 --> 00:02:14.090 everything. Everything. From how a billion -dollar 00:02:14.090 --> 00:02:16.949 company structures its global supply chain to 00:02:16.949 --> 00:02:20.629 how a new parent decides whether it's even worth 00:02:20.629 --> 00:02:23.020 it to go back to work. OK, let's start with those 00:02:23.020 --> 00:02:24.919 rates, because this is where you can instantly 00:02:24.919 --> 00:02:28.199 see the policy philosophy of a nation. And globally, 00:02:28.379 --> 00:02:30.659 there are really only two main ways to structure 00:02:30.659 --> 00:02:34.120 them. That's right. First, you have the progressive 00:02:34.120 --> 00:02:37.400 or graduated tax rate system. This is what most 00:02:37.400 --> 00:02:39.099 people think of when they hear individual income 00:02:39.099 --> 00:02:42.039 tax. So talk to us about the philosophy behind 00:02:42.039 --> 00:02:44.680 that. Why not just a single, simple rate for 00:02:44.680 --> 00:02:47.580 everybody? What's the point of progression? Well, 00:02:47.620 --> 00:02:49.879 a progressive system is built on this core principle 00:02:49.879 --> 00:02:53.409 of ability to pay. It's a mechanism that's specifically 00:02:53.409 --> 00:02:56.830 designed to distribute the tax burden. How? By 00:02:56.830 --> 00:02:58.770 increasing the marginal rate as taxable income 00:02:58.770 --> 00:03:00.870 goes up. So it's not just about collecting revenue? 00:03:01.250 --> 00:03:04.349 No, not at all. It's an explicitly social policy 00:03:04.349 --> 00:03:06.810 tool. We hear about tax brackets all the time. 00:03:06.889 --> 00:03:09.030 Can you just nail down what that looks like in 00:03:09.030 --> 00:03:12.099 practice for us? Sure. In practice, it means 00:03:12.099 --> 00:03:15.080 your income is divided up into tranches or brackets. 00:03:15.340 --> 00:03:18.960 So, for instance, the first, say, $10 ,000 of 00:03:18.960 --> 00:03:22.379 income might be taxed at 0 % or maybe 1%. That's 00:03:22.379 --> 00:03:24.479 designed to protect low -income earners. But 00:03:24.479 --> 00:03:27.919 the highest tranche of income, let's say everything 00:03:27.919 --> 00:03:30.259 you earn over half a million dollars, that might 00:03:30.259 --> 00:03:34.080 be taxed at 35 % or even more. This structure 00:03:34.080 --> 00:03:37.080 ensures that, on average, a high -income earner 00:03:37.080 --> 00:03:39.520 pays a much higher proportion of their total 00:03:39.520 --> 00:03:41.379 income to the government. And this progressive 00:03:41.379 --> 00:03:44.000 design, it's almost universal for individuals. 00:03:44.520 --> 00:03:46.840 But when we look at businesses, at corporations, 00:03:47.139 --> 00:03:49.400 we see a totally different philosophy. Yeah, 00:03:49.439 --> 00:03:51.939 we shift almost entirely to a flat rate system 00:03:51.939 --> 00:03:54.500 for corporations in most places around the world. 00:03:54.560 --> 00:03:57.159 Here, the tax rate just stays constant. It doesn't 00:03:57.159 --> 00:03:59.259 matter if the corporation earns a million or 00:03:59.259 --> 00:04:01.800 a billion dollars in profit. Why do governments 00:04:01.800 --> 00:04:04.919 just throw out that ability to pay? principle 00:04:04.919 --> 00:04:07.000 when it comes to companies. What is the rationale 00:04:07.000 --> 00:04:09.800 for a flat corporate rate? There are a few arguments. 00:04:09.979 --> 00:04:14.560 The main one is the need for stability and predictability 00:04:14.560 --> 00:04:16.779 for business planning. I see. Corporations have 00:04:16.779 --> 00:04:19.779 to forecast their tax liabilities years in advance 00:04:19.779 --> 00:04:23.199 to make huge investment decisions. A constantly 00:04:23.199 --> 00:04:26.139 shifting progressive rate schedule, well, that 00:04:26.139 --> 00:04:28.220 introduces a lot of volatility. So that's one 00:04:28.220 --> 00:04:30.620 reason. The second big argument is that corporations 00:04:30.620 --> 00:04:32.819 don't really bear the tax burden themselves. 00:04:32.939 --> 00:04:35.850 They just pass it on. To who? To consumers in 00:04:35.850 --> 00:04:38.329 the form of higher prices or to their employees 00:04:38.329 --> 00:04:41.810 with lower wages or to shareholders through lower 00:04:41.810 --> 00:04:44.970 dividends. So the argument goes applying a progressive 00:04:44.970 --> 00:04:47.509 system to an entity that's just a collection 00:04:47.509 --> 00:04:50.730 mechanism is, well, philosophically kind of pointless. 00:04:50.990 --> 00:04:53.670 That is a fascinating tradeoff. You're basically 00:04:53.670 --> 00:04:56.550 sacrificing that social equity goal at the corporate 00:04:56.550 --> 00:04:58.910 level for the sake of economic stability and 00:04:58.910 --> 00:05:01.500 encouraging investment. Precisely. And that leads 00:05:01.500 --> 00:05:03.459 us right into defining who exactly is paying 00:05:03.459 --> 00:05:05.800 the tax. We've mentioned individuals and corporations, 00:05:06.060 --> 00:05:09.220 but the world of taxable entities is a lot more 00:05:09.220 --> 00:05:11.019 nuanced than that. And I know the U .S. is a 00:05:11.019 --> 00:05:13.120 huge outlier here, right, when it comes to defining 00:05:13.120 --> 00:05:15.839 what a business even is for tax purposes. It 00:05:15.839 --> 00:05:19.980 really is. Globally, most systems tax an entity 00:05:19.980 --> 00:05:22.879 based on its legal formation. A corporation is 00:05:22.879 --> 00:05:25.899 a corporation. End of story. Simple enough. But 00:05:25.899 --> 00:05:28.540 the U .S. system stands out because many entities 00:05:28.540 --> 00:05:31.279 can actually elect their tax identity. They might 00:05:31.279 --> 00:05:33.899 be legally organized as an LLC, but they can 00:05:33.899 --> 00:05:37.040 choose, they literally check the box, to be treated 00:05:37.040 --> 00:05:39.399 as a corporation or as a partnership for tax 00:05:39.399 --> 00:05:41.579 purposes. And that flexibility, that choice, 00:05:41.660 --> 00:05:45.420 must be a huge lever for tax planners. Oh, it's 00:05:45.420 --> 00:05:48.079 a massive planning opportunity. And that brings 00:05:48.079 --> 00:05:50.160 us to the other major structure, partnerships. 00:05:50.879 --> 00:05:53.399 How are they treated? Partnerships are generally 00:05:53.399 --> 00:05:55.860 treated as pass -through entities. The income, 00:05:56.000 --> 00:05:58.079 the deductions, the credits, they don't stop 00:05:58.079 --> 00:06:00.079 at the business level. They pass through? They 00:06:00.079 --> 00:06:01.899 pass directly through to the individual partners 00:06:01.899 --> 00:06:04.879 who own the business. Those partners then report 00:06:04.879 --> 00:06:07.279 their share on their personal tax returns, where 00:06:07.279 --> 00:06:09.459 the progressive rates apply. And the goal there 00:06:09.459 --> 00:06:12.639 is to avoid what they call double taxation. Exactly. 00:06:12.779 --> 00:06:15.019 You want to avoid taxing the business and then 00:06:15.019 --> 00:06:16.860 taxing the owners again when they take the money 00:06:16.860 --> 00:06:19.019 out. Okay, so we've covered the structure of 00:06:19.019 --> 00:06:21.639 the payer. Is it an individual, a corporation, 00:06:22.040 --> 00:06:24.660 a pass -through? But what about the source of 00:06:24.660 --> 00:06:27.579 the income? Are my wages treated the same as 00:06:27.579 --> 00:06:30.040 my dividends? In most systems, the source of 00:06:30.040 --> 00:06:32.779 income absolutely matters. And this gets us into 00:06:32.779 --> 00:06:36.420 income variances and exemptions. Income from 00:06:36.420 --> 00:06:39.040 investments, things like dividends, capital gains, 00:06:39.199 --> 00:06:42.439 interest, is very often taxed at different and 00:06:42.439 --> 00:06:45.720 usually lower rates than your active wage income. 00:06:46.019 --> 00:06:48.800 And what's the policy driver behind giving investment 00:06:48.800 --> 00:06:51.379 income a break? Again, it's mostly an economic 00:06:51.379 --> 00:06:54.620 incentive. It's aimed at capital formation. Governments 00:06:54.620 --> 00:06:57.879 want people to save, to invest, to risk their 00:06:57.879 --> 00:06:59.920 capital because that's what drives economic growth. 00:07:00.300 --> 00:07:02.800 So if you tax it too heavily. If the return on 00:07:02.800 --> 00:07:04.720 that investment is heavily taxed, people are 00:07:04.720 --> 00:07:06.720 just more likely to spend their money rather 00:07:06.720 --> 00:07:08.860 than save or invest it. And, you know, there's 00:07:08.860 --> 00:07:11.220 all that double taxation idea again. The corporate 00:07:11.220 --> 00:07:14.279 profit was already taxed once at the flat corporate 00:07:14.279 --> 00:07:16.459 rate. So taxing the dividend that comes from 00:07:16.459 --> 00:07:19.060 it at the full individual rate is seen by many 00:07:19.060 --> 00:07:21.779 as excessive. And speaking of not taxing things, 00:07:21.959 --> 00:07:24.000 certain organizations are just taken out of the 00:07:24.000 --> 00:07:27.360 system entirely. Yes. Almost every jurisdiction 00:07:27.360 --> 00:07:30.089 in the world. recognizes the public good that's 00:07:30.089 --> 00:07:33.110 provided by schools, hospitals, social welfare 00:07:33.110 --> 00:07:37.089 groups. So local charitable organizations are 00:07:37.089 --> 00:07:40.069 almost universally exempted from income tax. 00:07:40.889 --> 00:07:43.670 It's a deliberate policy choice to encourage 00:07:43.670 --> 00:07:45.750 private funding for things that benefit the public. 00:07:45.910 --> 00:07:47.490 Okay, last thing before we leave these building 00:07:47.490 --> 00:07:49.850 blocks, we have to talk about the most powerful 00:07:49.850 --> 00:07:53.470 tool in the toolbox, the tax credit. What makes 00:07:53.470 --> 00:07:55.769 a credit so different from a deduction? This 00:07:55.769 --> 00:07:58.100 is a really crucial distinction. A deduction 00:07:58.100 --> 00:08:00.759 only reduces your taxable income base. So if 00:08:00.759 --> 00:08:03.079 you're in a 20 % bracket, a $100 deduction saves 00:08:03.079 --> 00:08:06.939 you $20 in actual tax. Okay. But a credit is 00:08:06.939 --> 00:08:09.439 a dollar -for -dollar reduction of your final 00:08:09.439 --> 00:08:11.920 tax liability. So a credit hits the final bill 00:08:11.920 --> 00:08:14.980 directly. Precisely. If you have a $500 tax bill 00:08:14.980 --> 00:08:17.300 and you get a $100 credit, your bill immediately 00:08:17.300 --> 00:08:20.480 drops to $400. Credits are a much more potent 00:08:20.480 --> 00:08:22.939 and therefore more expensive for the government 00:08:22.939 --> 00:08:26.160 policy tool. But their function is uniform everywhere. 00:08:26.680 --> 00:08:28.160 All right, now we get to jump back through time 00:08:28.160 --> 00:08:30.920 and see how this incredibly complex system actually 00:08:30.920 --> 00:08:33.860 came to be. When we think of tax, you know, we 00:08:33.860 --> 00:08:36.039 often think of simple things, levies on land 00:08:36.039 --> 00:08:39.740 or sales. But a modern income tax requires some 00:08:39.740 --> 00:08:42.940 serious administrative sophistication. Oh, absolutely. 00:08:43.399 --> 00:08:46.259 For a government to even attempt a modern income 00:08:46.259 --> 00:08:49.759 tax system, you need a few key things. You need 00:08:49.759 --> 00:08:52.940 a functioning money economy, not barter. You 00:08:52.940 --> 00:08:55.919 need systems for accurate accounting. A common 00:08:55.919 --> 00:08:59.059 understanding of what profit even means. Exactly. 00:08:59.100 --> 00:09:02.799 A common legal understanding of receipts, expenses, 00:09:03.159 --> 00:09:05.340 profit, this whole idea of net income. Right. 00:09:05.419 --> 00:09:07.960 And crucially, you need reliable records and 00:09:07.960 --> 00:09:10.200 a bureaucracy strong enough to enforce it all. 00:09:10.549 --> 00:09:12.950 And that structural requirement is why those 00:09:12.950 --> 00:09:15.509 older systems like tithing, which focused on 00:09:15.509 --> 00:09:17.850 a piece of your gross output, were so fundamentally 00:09:17.850 --> 00:09:20.330 different from what we have today. Right. Tithing 00:09:20.330 --> 00:09:22.429 and ancient property taxes, they were assessments 00:09:22.429 --> 00:09:25.110 on gross items or on wealth ownership. They didn't 00:09:25.110 --> 00:09:27.110 have the precision you need to calculate true 00:09:27.110 --> 00:09:30.210 profit or the net increase in your wealth over 00:09:30.210 --> 00:09:32.909 a specific period. But there's one really surprising 00:09:32.909 --> 00:09:35.389 detail in our sources that shows this idea of 00:09:35.389 --> 00:09:38.200 taxing net income isn't new at all. It's not. 00:09:38.320 --> 00:09:40.799 The history books take us way out of Europe, 00:09:40.820 --> 00:09:44.259 all the way to 9 CE China. To the Xin Dynasty? 00:09:44.539 --> 00:09:47.279 Yes, to the very short -lived Xin Dynasty under 00:09:47.279 --> 00:09:50.090 Emperor Wang Meng. Our sources pinpoint this 00:09:50.090 --> 00:09:52.750 as the very first documented income tax that 00:09:52.750 --> 00:09:55.309 was based on the principle of net earnings. This 00:09:55.309 --> 00:09:58.110 is just fascinating. What prompted this massive 00:09:58.110 --> 00:10:01.029 administrative leap 2 ,000 years ago? Wang Meng 00:10:01.029 --> 00:10:04.210 was a really ambitious reformer. He established 00:10:04.210 --> 00:10:06.870 a 10 % tax, but not on everything. It was on 00:10:06.870 --> 00:10:09.649 the net earnings from specific activities, non 00:10:09.649 --> 00:10:12.529 -agricultural trading, fishing, wild herb and 00:10:12.529 --> 00:10:14.960 fruit collection, shepherding. The sheer administrative 00:10:14.960 --> 00:10:17.480 complexity of trying to define net earnings for, 00:10:17.580 --> 00:10:21.740 say, a rural trader in 9CE China is just astonishing. 00:10:22.000 --> 00:10:24.379 It is. And the compliance mechanism they developed 00:10:24.379 --> 00:10:26.559 sounds frighteningly familiar to what we do today. 00:10:26.720 --> 00:10:29.100 How so? People were required to self -report 00:10:29.100 --> 00:10:31.179 their income. And just like today, the government 00:10:31.179 --> 00:10:33.659 didn't just take their word for it. Officials 00:10:33.659 --> 00:10:35.860 would actually audit the self -reported figures 00:10:35.860 --> 00:10:38.279 to check for compliance. And I'm guessing the 00:10:38.279 --> 00:10:40.440 penalties for getting caught were not small. 00:10:40.679 --> 00:10:43.379 Not at all. They were brutal. Tax evasion was 00:10:43.379 --> 00:10:45.879 penalized with a full year of hard labor and, 00:10:46.000 --> 00:10:48.299 this is the kicker, confiscation of all your 00:10:48.299 --> 00:10:51.120 property. Wow. And penalties that severe, they 00:10:51.120 --> 00:10:53.480 suggest the system was incredibly difficult to 00:10:53.480 --> 00:10:56.419 enforce and probably met with immediate resistance, 00:10:56.720 --> 00:11:00.019 which it was. It was abolished in 22 CE after 00:11:00.019 --> 00:11:03.799 only 13 years because of widespread popular discontent. 00:11:04.019 --> 00:11:07.389 So a short -lived but radical experiment. Now, 00:11:07.429 --> 00:11:10.529 jumping forward, early Rome had taxes, but they 00:11:10.529 --> 00:11:12.870 weren't based on annual profit, were they? No, 00:11:12.909 --> 00:11:14.990 Rome had a wealth tax. During the early Republic, 00:11:15.190 --> 00:11:17.330 they had these modest assessments, usually 1%, 00:11:17.330 --> 00:11:20.049 maybe up to 3 % during a war. But it was applied 00:11:20.049 --> 00:11:24.470 to property you owned, lands, slaves. money it 00:11:24.470 --> 00:11:26.590 was a snapshot of what you had not a calculation 00:11:26.590 --> 00:11:28.730 of what you earned then we hit the medieval period 00:11:28.730 --> 00:11:31.590 with the very famous salad and tithe right the 00:11:31.590 --> 00:11:34.990 salad and tithe in 1188 imposed by henry ii this 00:11:34.990 --> 00:11:36.950 starts to look a lot more like a precursor to 00:11:36.950 --> 00:11:40.029 an income tax it required one -tenth of a lay 00:11:40.029 --> 00:11:42.529 person's personal income and their movable property 00:11:42.529 --> 00:11:45.110 and this was in england and wales the money was 00:11:45.110 --> 00:11:47.659 to fund the third crusade So it was an emergency 00:11:47.659 --> 00:11:50.799 measure, but that specific link to personal income 00:11:50.799 --> 00:11:53.399 suggests a real evolution in how they were measuring 00:11:53.399 --> 00:11:56.100 wealth. And then finally, 17th century Portugal 00:11:56.100 --> 00:11:59.379 gives us a truly early modern example. In 1641, 00:11:59.639 --> 00:12:02.279 yeah, Portugal introduced the décima, which was 00:12:02.279 --> 00:12:04.240 specifically categorized as a personal income 00:12:04.240 --> 00:12:07.000 tax. But while you see these examples popping 00:12:07.000 --> 00:12:10.450 up... the real inception of the modern, structured, 00:12:10.549 --> 00:12:13.649 progressive income tax, the direct ancestor of 00:12:13.649 --> 00:12:16.830 what we know today. That's 1799 Britain. Tell 00:12:16.830 --> 00:12:18.669 us about that. This was William Pitt the Younger, 00:12:18.690 --> 00:12:21.110 and the context was the French Revolutionary 00:12:21.110 --> 00:12:24.210 Wars. Exactly. Pitt needed a huge amount of money 00:12:24.210 --> 00:12:26.230 to fight Napoleon, and the traditional methods 00:12:26.230 --> 00:12:27.970 just couldn't raise the kind of sums required. 00:12:28.549 --> 00:12:31.970 So in 1799, he introduced the tax, but, and this 00:12:31.970 --> 00:12:33.950 is important, he introduced it explicitly as 00:12:33.950 --> 00:12:35.909 a temporary war measure. And it was progressive 00:12:35.909 --> 00:12:39.690 from day one. Yes, although modestly. It started 00:12:39.690 --> 00:12:43.090 at a tiny rate for lower incomes, two old pence 00:12:43.090 --> 00:12:45.529 in the pound for incomes over 60 pounds, and 00:12:45.529 --> 00:12:47.750 it climbed progressively to a maximum of 10 % 00:12:47.750 --> 00:12:51.649 on incomes over 200 pounds. So that concept of 00:12:51.649 --> 00:12:54.289 capacity to pay was baked in from the start. 00:12:54.649 --> 00:12:57.070 But the tax was incredibly unpopular precisely 00:12:57.070 --> 00:12:59.389 because it was supposed to be temporary and linked 00:12:59.389 --> 00:13:02.149 only to the war. This led to that wonderful story 00:13:02.149 --> 00:13:04.350 when it was repealed after Napoleon was finally 00:13:04.350 --> 00:13:06.269 defeated. Right. So when it was abolished in 00:13:06.269 --> 00:13:09.669 1816 after Waterloo, the opposition was so loud 00:13:09.669 --> 00:13:12.669 and so angry that they demanded all the tax records 00:13:12.669 --> 00:13:15.850 be publicly and ceremoniously destroyed. It was 00:13:15.850 --> 00:13:18.690 a signal that this tax was dead forever. And 00:13:18.690 --> 00:13:20.549 the government agreed. The chancellor of the 00:13:20.549 --> 00:13:23.289 Exchequer complied. He publicly burned the records. 00:13:23.710 --> 00:13:26.070 But the bureaucracy, as always, had the last 00:13:26.070 --> 00:13:28.669 laugh. Exactly. We know the copies of those records 00:13:28.669 --> 00:13:30.490 were secretly kept in the basement of the tax 00:13:30.490 --> 00:13:33.049 court. It's just a perfect example of the enduring 00:13:33.049 --> 00:13:35.929 administrative instinct of government. Even when 00:13:35.929 --> 00:13:38.250 you're defeated politically, information is power 00:13:38.250 --> 00:13:41.350 and records are never truly destroyed. And despite 00:13:41.350 --> 00:13:44.149 all that opposition. Income tax eventually came 00:13:44.149 --> 00:13:46.330 back to the UK as a permanent thing. It did. 00:13:46.429 --> 00:13:48.769 That happened in 1842 under Sir Robert Peel. 00:13:48.850 --> 00:13:51.649 And Peel was initially against the tax, but a 00:13:51.649 --> 00:13:54.129 severe and persistent budget deficit basically 00:13:54.129 --> 00:13:56.850 forced his hand. He reintroduced it. And despite 00:13:56.850 --> 00:13:59.409 all the opposition, it eventually became, you 00:13:59.409 --> 00:14:01.230 know, grudgingly accepted as an indispensable 00:14:01.230 --> 00:14:03.690 part of government funding by the mid 19th century. 00:14:03.830 --> 00:14:06.789 And the story in the US really mirrors that pattern. 00:14:06.990 --> 00:14:09.730 Wartime necessity driving fiscal innovation. 00:14:09.830 --> 00:14:11.929 Absolutely. The U .S. federal government brought 00:14:11.929 --> 00:14:15.450 in its first personal income tax in 1861 to fund 00:14:15.450 --> 00:14:18.110 the Civil War. It was a modest 3 % on incomes 00:14:18.110 --> 00:14:21.230 over $800. It was quickly changed, later repealed. 00:14:21.289 --> 00:14:23.389 The first real peacetime attempt didn't come 00:14:23.389 --> 00:14:27.210 until 1894. And that 1894 tax, it was meant to 00:14:27.210 --> 00:14:30.070 replace lost tariff revenue, but it ran into 00:14:30.070 --> 00:14:32.149 a much bigger problem than political opposition. 00:14:32.330 --> 00:14:35.090 It ran into the Constitution. That is the critical 00:14:35.090 --> 00:14:37.549 pivot point in U .S. tax history. The Supreme 00:14:37.549 --> 00:14:40.509 Court ruled the 1894 income tax unconstitutional. 00:14:40.690 --> 00:14:43.970 The 10th Amendment required direct taxes to be 00:14:43.970 --> 00:14:45.870 apportioned among the states based on population. 00:14:46.490 --> 00:14:49.970 The court decided that a tax on income from property 00:14:49.970 --> 00:14:53.129 like rent or interest was a direct tax and therefore 00:14:53.129 --> 00:14:55.409 had to be apportioned, which for an income tax 00:14:55.409 --> 00:14:58.389 is administratively impossible. So the U .S. 00:14:58.429 --> 00:15:00.789 system was just legally stuck. They had to literally 00:15:00.789 --> 00:15:03.610 change the foundational law of the country. Correct. 00:15:03.750 --> 00:15:06.029 That monumental change was the 16th Amendment 00:15:06.029 --> 00:15:09.669 in 1913. And it specifically gave Congress the 00:15:09.669 --> 00:15:12.610 power to lay and collect taxes on incomes, quote, 00:15:12.750 --> 00:15:15.610 from whatever source derived without apportionment 00:15:15.610 --> 00:15:17.870 among the several states. And that amendment 00:15:17.870 --> 00:15:21.289 was like. Opening the floodgates. It was. Revenue 00:15:21.289 --> 00:15:23.389 soared. It passed the billion dollar mark by 00:15:23.389 --> 00:15:26.710 1918. And the rates began this dramatic fluctuation 00:15:26.710 --> 00:15:28.830 that you see throughout 20th century tax policy. 00:15:28.929 --> 00:15:32.269 Wild swings. Absolutely. From a low of 1 % in 00:15:32.269 --> 00:15:34.250 the early brackets to these staggering highest 00:15:34.250 --> 00:15:36.789 marginal rates of over 90 % that were used to 00:15:36.789 --> 00:15:39.309 fund World War II. It just shows the incredible 00:15:39.309 --> 00:15:43.129 power of income tax as a lever for massive governmental 00:15:43.129 --> 00:15:45.840 mobilization. And if you look at the global timeline, 00:15:46.200 --> 00:15:48.799 once the U .K. and U .S. models were in place 00:15:48.799 --> 00:15:51.940 and working, adoption just became rapid. It was 00:15:51.940 --> 00:15:54.120 mostly driven by industrialization and the need 00:15:54.120 --> 00:15:56.779 to fund big state projects or wars. You see it 00:15:56.779 --> 00:16:00.500 everywhere. Switzerland in 1840, Japan in 1887, 00:16:00.840 --> 00:16:04.600 France starts to evolve its system in 1872, Canada 00:16:04.600 --> 00:16:07.500 in 1918. And it's important to remember this 00:16:07.500 --> 00:16:10.220 isn't a finished story. I mean, Uruguay only 00:16:10.220 --> 00:16:13.240 introduced a personal income tax in 2007. Wow. 00:16:13.610 --> 00:16:16.210 So this transition from systems that rely on 00:16:16.210 --> 00:16:18.590 tariffs or consumption to systems that rely on 00:16:18.590 --> 00:16:21.730 income, it's a global, continuous process. So 00:16:21.730 --> 00:16:24.029 history shows us that income tax is sticky. Once 00:16:24.029 --> 00:16:25.830 it's implemented, it's really hard to get rid 00:16:25.830 --> 00:16:27.950 of. Now let's transition into how this money 00:16:27.950 --> 00:16:29.870 is actually collected today, focusing on the 00:16:29.870 --> 00:16:31.870 shared mechanics that really bind almost all 00:16:31.870 --> 00:16:33.850 global systems together, no matter the local 00:16:33.850 --> 00:16:36.210 politics. The first and most important shared 00:16:36.210 --> 00:16:38.450 principle, the one that immediately dictates 00:16:38.450 --> 00:16:41.070 how complex your tax life is, is the system of 00:16:41.070 --> 00:16:43.669 residency rules and worldwide taxation. OK, we 00:16:43.669 --> 00:16:45.289 need to really clarify the fundamental difference 00:16:45.289 --> 00:16:47.669 here. How is a tax resident treated versus a 00:16:47.669 --> 00:16:50.769 non -resident? OK, so a resident, and that can 00:16:50.769 --> 00:16:53.730 be a person or a company, is generally subject 00:16:53.730 --> 00:16:56.870 to tax on their worldwide income. Worldwide. 00:16:56.970 --> 00:16:59.389 Worldwide. So if you're a tax resident of Germany, 00:16:59.610 --> 00:17:02.350 you have to report the income from your job in 00:17:02.350 --> 00:17:04.529 Germany, but also from your rental property in 00:17:04.529 --> 00:17:07.670 Spain and from your investments in Asia. All 00:17:07.670 --> 00:17:10.859 of it. That is incredibly expansive. What about 00:17:10.859 --> 00:17:13.720 the non -resident then? A non -resident is taxed 00:17:13.720 --> 00:17:16.160 only on specific types of income that are sourced 00:17:16.160 --> 00:17:18.640 within that jurisdiction. So if you live in Canada 00:17:18.640 --> 00:17:20.380 but you own a building that generates rent in 00:17:20.380 --> 00:17:22.680 Germany, Germany is only going to tax you on 00:17:22.680 --> 00:17:24.759 that specific rental income from the German property. 00:17:25.140 --> 00:17:28.119 So how do countries define residency for an individual, 00:17:28.420 --> 00:17:31.559 especially now in a world of remote work and 00:17:31.559 --> 00:17:34.319 global travel? For individuals, the rule is often 00:17:34.319 --> 00:17:36.680 pretty quantitative and simple. It's a physical 00:17:36.680 --> 00:17:38.599 presence test. If you're physically present for 00:17:38.599 --> 00:17:41.599 more than 183 days, so roughly half the year, 00:17:41.779 --> 00:17:44.259 you're often deemed a resident for tax purposes. 00:17:44.460 --> 00:17:46.500 And for companies. For corporations, it's usually 00:17:46.500 --> 00:17:48.519 based on either the place of legal organization 00:17:48.519 --> 00:17:52.000 or, and this gets more complex, where the company's 00:17:52.000 --> 00:17:54.099 management and control actually happens. This 00:17:54.099 --> 00:17:56.400 dual system immediately creates the potential 00:17:56.400 --> 00:17:59.359 for double taxation. It does. If I'm a German 00:17:59.359 --> 00:18:01.519 resident, but my Spanish property is taxed in 00:18:01.519 --> 00:18:03.680 Spain, I'm being taxed twice on the same money. 00:18:04.039 --> 00:18:05.980 And that is the single biggest challenge of the 00:18:05.980 --> 00:18:08.559 worldwide residential system. Double taxation 00:18:08.559 --> 00:18:11.400 happens when one country claims you as a resident 00:18:11.400 --> 00:18:14.059 and another country taxes you as a non -resident 00:18:14.059 --> 00:18:16.220 on the income you earn there. So how do they 00:18:16.220 --> 00:18:20.140 fix this? To mitigate this huge barrier to global 00:18:20.140 --> 00:18:22.740 trade and movement, nearly all countries enter 00:18:22.740 --> 00:18:25.220 into double taxation avoidance agreements, or 00:18:25.220 --> 00:18:28.900 DTAs. DTIA sound incredibly important. How do 00:18:28.900 --> 00:18:31.940 they actually work? A DTIA is a bilateral treaty 00:18:31.940 --> 00:18:34.740 between two countries. It dictates which country 00:18:34.740 --> 00:18:37.059 gets the first right to tax a specific type of 00:18:37.059 --> 00:18:39.859 income. And maybe more importantly, it ensures 00:18:39.859 --> 00:18:42.240 that the resident country has to offer relief 00:18:42.240 --> 00:18:44.579 for the tax that was already paid to the source 00:18:44.579 --> 00:18:46.759 country. And they do that with a credit? Usually 00:18:46.759 --> 00:18:48.910 with a foreign tax credit, yes. That offsets 00:18:48.910 --> 00:18:51.450 the tax paid somewhere else. Without these thousands 00:18:51.450 --> 00:18:53.609 of treaties, I mean, global business would just 00:18:53.609 --> 00:18:56.450 grind to a halt under crippling compounded tax 00:18:56.450 --> 00:18:58.349 burdens. It's important to remember, though, 00:18:58.369 --> 00:19:00.869 that a few jurisdictions just completely reject 00:19:00.869 --> 00:19:03.849 this worldwide tax model. They do. Places like 00:19:03.849 --> 00:19:06.569 Singapore and Hong Kong, for example, they operate 00:19:06.569 --> 00:19:09.210 largely on a territorial basis, even for their 00:19:09.210 --> 00:19:12.890 residents. They only tax residents on income. 00:19:13.500 --> 00:19:16.240 that's earned in or actually remitted to the 00:19:16.240 --> 00:19:17.960 jurisdiction itself. And that's a deliberate 00:19:17.960 --> 00:19:20.400 choice. Oh, it's a very deliberate design choice, 00:19:20.559 --> 00:19:23.200 often aimed at making the jurisdiction extremely 00:19:23.200 --> 00:19:25.680 attractive for internationally mobile wealth. 00:19:25.960 --> 00:19:27.960 Okay, let's move on to the second fundamental 00:19:27.960 --> 00:19:31.740 shared principle, defining taxable income. For 00:19:31.740 --> 00:19:33.880 residents, you said the definition is generally 00:19:33.880 --> 00:19:36.339 broad. What are the key things we see included 00:19:36.339 --> 00:19:39.740 everywhere? Income is broadly defined as any 00:19:39.740 --> 00:19:42.430 receipt that enriches the taxpayer. This includes 00:19:42.430 --> 00:19:45.849 compensation for services, wages, salary, bonuses, 00:19:46.049 --> 00:19:48.549 but also things like the net gain from selling 00:19:48.549 --> 00:19:51.390 property, interest, dividends, rent, royalties, 00:19:51.509 --> 00:19:54.069 annuities, and pensions. I want to focus on that 00:19:54.069 --> 00:19:58.130 detail. Net gain from the sale of property. Why 00:19:58.130 --> 00:20:00.690 is that wording so important to the idea of fairness? 00:20:01.190 --> 00:20:02.910 Well, it's the difference between taxing wealth 00:20:02.910 --> 00:20:05.430 movement and taxing wealth generation. Explain 00:20:05.430 --> 00:20:08.410 that. If you buy a stock for $100 and you sell 00:20:08.410 --> 00:20:12.049 it for $100, no wealth was generated. So you 00:20:12.049 --> 00:20:14.690 shouldn't be taxed, even though $100 passed through 00:20:14.690 --> 00:20:18.170 your hands. Tax is only imposed on the $10 of 00:20:18.170 --> 00:20:21.990 net gain if you sell it for $110. And that concept 00:20:21.990 --> 00:20:24.210 applies to real estate and other assets globally. 00:20:24.809 --> 00:20:27.569 Are there any universal exclusions from this 00:20:27.569 --> 00:20:30.230 broad definition, things that are left out for 00:20:30.230 --> 00:20:33.140 policy reasons? Yes. Two big ones are common 00:20:33.140 --> 00:20:35.839 globally. First, national retirement payments 00:20:35.839 --> 00:20:39.079 are often fully or partially excluded from current 00:20:39.079 --> 00:20:41.839 income tax. That's a policy choice to encourage 00:20:41.839 --> 00:20:44.480 retirement savings or maybe to just defer the 00:20:44.480 --> 00:20:46.880 tax until retirement. And the second? The second 00:20:46.880 --> 00:20:49.259 is employer -provided health care benefits. They 00:20:49.259 --> 00:20:51.670 are typically excluded. And this is a subtle 00:20:51.670 --> 00:20:54.549 but massive subsidy that governments use to encourage 00:20:54.549 --> 00:20:57.589 employers to provide health coverage, which promotes 00:20:57.589 --> 00:20:59.730 public health without them having to directly 00:20:59.730 --> 00:21:02.250 fund it. So once we have our gross income, we 00:21:02.250 --> 00:21:04.730 need to subtract the costs of generating that 00:21:04.730 --> 00:21:07.230 income. Let's talk about allowable deductions 00:21:07.230 --> 00:21:10.289 and business profits. The principle here is foundational. 00:21:11.009 --> 00:21:15.420 Tax is imposed on profit, not revenue. So expenses 00:21:15.420 --> 00:21:17.980 that you incur in the process of generating income, 00:21:18.220 --> 00:21:21.339 running a business, renting out a property, are 00:21:21.339 --> 00:21:23.819 generally deductible against that gross income. 00:21:24.180 --> 00:21:26.299 That's why only the net income from a business 00:21:26.299 --> 00:21:29.259 is taxable. What about non -residents? We said 00:21:29.259 --> 00:21:30.920 they're taxed on source income. Is that usually 00:21:30.920 --> 00:21:33.299 on the gross amount or the net? Non -residents 00:21:33.299 --> 00:21:35.099 are often taxed on the gross amount of certain 00:21:35.099 --> 00:21:37.900 passive income, like royalties. Just simpler 00:21:37.900 --> 00:21:40.480 administratively. However, if they're earning 00:21:40.480 --> 00:21:42.920 net business income in the jurisdiction like 00:21:42.920 --> 00:21:45.200 operating a branch office, then they're allowed 00:21:45.200 --> 00:21:48.380 to deduct the expenses related to that local 00:21:48.380 --> 00:21:50.940 business activity. How do systems account for 00:21:50.940 --> 00:21:53.599 long -term investments, like buying a huge piece 00:21:53.599 --> 00:21:56.059 of machinery or a factory? You can't just deduct 00:21:56.059 --> 00:21:58.779 the entire cost in one year. No, that's managed 00:21:58.779 --> 00:22:00.319 through what's called a capital allowance or 00:22:00.319 --> 00:22:03.059 depreciation deduction. Systems all over the 00:22:03.059 --> 00:22:05.400 world allow businesses to recover the cost of 00:22:05.400 --> 00:22:08.259 those long -term assets over time. But here's 00:22:08.259 --> 00:22:10.799 where tax policy gets very interesting. The rules 00:22:10.799 --> 00:22:13.700 often permit businesses to recover those costs 00:22:13.700 --> 00:22:16.380 more quickly than the actual physical life of 00:22:16.380 --> 00:22:19.279 the asset would suggest. So the government deliberately 00:22:19.279 --> 00:22:22.599 allows accelerated depreciation. What's the point 00:22:22.599 --> 00:22:25.359 of that mechanism? It's a huge economic incentive. 00:22:25.660 --> 00:22:29.140 By letting businesses deduct costs sooner, you 00:22:29.140 --> 00:22:31.539 lower their current year's tax bill, which improves 00:22:31.539 --> 00:22:33.880 their cash flow and makes the investment more 00:22:33.880 --> 00:22:36.500 attractive. It's essentially a government subsidy 00:22:36.500 --> 00:22:38.680 for the decision to invest in new equipment or 00:22:38.680 --> 00:22:40.819 facilities, and it drives capital expenditure. 00:22:41.180 --> 00:22:44.119 Turning to individuals, aside from business costs. 00:22:44.759 --> 00:22:46.900 What kind of personal expenses are generally 00:22:46.900 --> 00:22:50.319 deductible across different systems? Most jurisdictions 00:22:50.319 --> 00:22:53.019 start with a notional deduction. It's a fixed 00:22:53.019 --> 00:22:54.640 amount of income that everyone gets to earn, 00:22:54.740 --> 00:22:57.400 subject to zero tax, which ensures that very 00:22:57.400 --> 00:23:01.180 low earners pay nothing. Beyond that, many systems 00:23:01.180 --> 00:23:03.619 let you deduct certain personal costs, like most 00:23:03.619 --> 00:23:06.559 famously home mortgage interest or medical costs. 00:23:06.700 --> 00:23:08.500 Which is another subsidy? It's another subsidy, 00:23:08.680 --> 00:23:11.539 yeah. Designed to encourage specific social behaviors, 00:23:11.720 --> 00:23:13.740 like home ownership. Okay, let's look at the 00:23:13.740 --> 00:23:16.099 administration of this. How do tax authorities 00:23:16.099 --> 00:23:19.900 even determine a business's net profit? For major 00:23:19.900 --> 00:23:22.660 domestic companies, many countries rely heavily 00:23:22.660 --> 00:23:25.559 on their audited financial statements. The taxable 00:23:25.559 --> 00:23:28.000 income is often closely tied to the profit they 00:23:28.000 --> 00:23:30.359 report in their official books, with just a few 00:23:30.359 --> 00:23:33.460 adjustments. But for, say, a non -resident company 00:23:33.460 --> 00:23:35.819 operating a local branch where accounting is 00:23:35.819 --> 00:23:38.880 tricky, some jurisdictions simplify. How? They 00:23:38.880 --> 00:23:41.500 might just compute the taxable net income as 00:23:41.500 --> 00:23:43.940 a fixed percentage of gross revenues and just 00:23:43.940 --> 00:23:46.140 ignore the complexity of the local expense report 00:23:46.140 --> 00:23:48.319 entirely. We mentioned the foreign tax credit 00:23:48.319 --> 00:23:50.799 earlier. Let's confirm how critical that is. 00:23:50.980 --> 00:23:53.720 It is the glue that holds the entire residential 00:23:53.720 --> 00:23:57.039 worldwide system together. Without it, the combined 00:23:57.039 --> 00:24:00.400 tax burden would just be prohibitive. Every system 00:24:00.400 --> 00:24:02.440 that taxes its residents on worldwide income 00:24:02.440 --> 00:24:05.140 has to offer this credit to stay functional and 00:24:05.140 --> 00:24:07.640 competitive. And some countries, like the U .S. 00:24:07.640 --> 00:24:08.960 and Switzerland, they complicate things even 00:24:08.960 --> 00:24:11.700 more with alternative taxes. They do. They often 00:24:11.700 --> 00:24:14.680 impose the higher of the regular complex income 00:24:14.680 --> 00:24:17.759 tax calculation or an alternative simpler tax. 00:24:18.319 --> 00:24:21.259 For corporations, this alternative might be based 00:24:21.259 --> 00:24:24.500 on capital or gross receipts rather than net 00:24:24.500 --> 00:24:26.500 income. And the goal there is just to make sure 00:24:26.500 --> 00:24:29.380 they pay something. Exactly. It ensures that 00:24:29.380 --> 00:24:31.619 even corporations that manage to reduce their 00:24:31.619 --> 00:24:34.460 taxable net income to zero through deductions 00:24:34.460 --> 00:24:37.099 and credits still contribute some minimum amount 00:24:37.099 --> 00:24:39.299 to the Treasury. OK, now let's dive into the 00:24:39.299 --> 00:24:41.539 two major ways the money actually gets collected. 00:24:42.019 --> 00:24:45.319 Administration and compliance. The first method 00:24:45.319 --> 00:24:47.640 is withholding, or what's sometimes called pay 00:24:47.640 --> 00:24:50.440 -e -pay as you earn. This is required for payments 00:24:50.440 --> 00:24:53.730 to employees and to non -residents. The employer 00:24:53.730 --> 00:24:56.710 or the payer acts as the collection agent. They 00:24:56.710 --> 00:24:58.829 deduct the expected tax amount before the money 00:24:58.829 --> 00:25:00.690 ever even reaches the recipient. But it's so 00:25:00.690 --> 00:25:02.690 important to understand that withholding is just 00:25:02.690 --> 00:25:05.170 an advance payment. It is not your final bill. 00:25:05.470 --> 00:25:07.710 Exactly. It's the government ensuring it has 00:25:07.710 --> 00:25:10.589 a steady cash flow. The final determination of 00:25:10.589 --> 00:25:13.170 what you owe falls to the taxpayer through the 00:25:13.170 --> 00:25:15.109 process of self -assessment. So you have to do 00:25:15.109 --> 00:25:17.339 the final math. You have to aggregate all your 00:25:17.339 --> 00:25:19.619 income sources, subtract your deductions, apply 00:25:19.619 --> 00:25:22.119 your credits, and calculate the actual final 00:25:22.119 --> 00:25:25.240 tax you owe. If more was withheld than you owed, 00:25:25.339 --> 00:25:28.099 you get a refund. If less, you have to pay the 00:25:28.099 --> 00:25:30.359 rest. And this brings us to this fascinating 00:25:30.359 --> 00:25:33.880 measure of civic cooperation, the voluntary compliance 00:25:33.880 --> 00:25:37.619 rate, or VCR. The VCR measures the proportion 00:25:37.619 --> 00:25:40.599 of taxes that are paid voluntarily, on time, 00:25:40.660 --> 00:25:42.839 and without the tax authority having to intervene. 00:25:43.230 --> 00:25:45.869 The US, for instance, has historically had a 00:25:45.869 --> 00:25:49.170 very high VCR, often cited as being above 80%. 00:25:49.170 --> 00:25:51.730 Why do these rates vary so much around the world? 00:25:51.910 --> 00:25:54.410 Our source material contrasts the US with countries 00:25:54.410 --> 00:25:57.309 like Germany or Italy. Well, compliance is heavily 00:25:57.309 --> 00:25:59.269 influenced by a country's administrative capacity. 00:26:00.039 --> 00:26:01.900 the public's perception of government integrity, 00:26:02.220 --> 00:26:04.500 and the size of the informal economy. The black 00:26:04.500 --> 00:26:06.660 market. The black market, exactly. In countries 00:26:06.660 --> 00:26:08.799 with a sizable black market where transactions 00:26:08.799 --> 00:26:11.859 are unrecorded and cash -based, the VCR naturally 00:26:11.859 --> 00:26:14.420 just plummets. And enforcing tax law becomes 00:26:14.420 --> 00:26:16.720 exponentially more difficult and expensive for 00:26:16.720 --> 00:26:18.900 the government. And finally, we need to remember 00:26:18.900 --> 00:26:21.759 that income tax often happens at multiple levels 00:26:21.759 --> 00:26:24.460 of government at the same time. That is vital 00:26:24.460 --> 00:26:26.700 to understand, particularly in federal systems 00:26:26.700 --> 00:26:29.160 like Canada, Germany, Switzerland, and the U 00:26:29.160 --> 00:26:32.480 .S. These systems impose income taxes separately 00:26:32.480 --> 00:26:35.980 at the subnational level, so provinces, cantons, 00:26:35.980 --> 00:26:38.799 or states, in addition to the national tax. And 00:26:38.799 --> 00:26:41.180 those can be linked or completely separate. Right. 00:26:41.240 --> 00:26:43.240 They can be integrated, where the state tax is 00:26:43.240 --> 00:26:45.019 just a fixed percentage of the national tax, 00:26:45.140 --> 00:26:48.460 or they can be entirely independent systems with 00:26:48.460 --> 00:26:50.579 different forms and different rules. And we can't 00:26:50.579 --> 00:26:52.980 forget the taxes that look and feel like income 00:26:52.980 --> 00:26:55.920 tax but serve a totally different social purpose. 00:26:56.599 --> 00:26:59.299 wage -based taxes. These are your Social Security, 00:26:59.420 --> 00:27:01.859 national insurance, or national pension contributions. 00:27:02.339 --> 00:27:04.660 While they are a levy on income, they're typically 00:27:04.660 --> 00:27:07.339 a fixed rate, often capped at a maximum annual 00:27:07.339 --> 00:27:10.400 earning level, and they are explicitly earmarked 00:27:10.400 --> 00:27:12.839 for things like retirement, unemployment, or 00:27:12.839 --> 00:27:14.759 health care systems. So it's a parallel system. 00:27:14.980 --> 00:27:17.000 It's a parallel form of income taxation, usually 00:27:17.000 --> 00:27:21.099 imposed on the employer, the employee, or very 00:27:21.099 --> 00:27:23.500 often both. All right, we've built the history 00:27:23.500 --> 00:27:25.920 and we've explained the global structure. Now 00:27:25.920 --> 00:27:28.359 we have to look at how income tax fundamentally 00:27:28.359 --> 00:27:31.720 changes behavior and creates these policy headaches 00:27:31.720 --> 00:27:35.559 for every single government on the planet. The 00:27:35.559 --> 00:27:37.740 core truth of taxation is that it introduces 00:27:37.740 --> 00:27:41.359 friction. It changes incentives and ultimately 00:27:41.359 --> 00:27:43.539 it changes how people decide to spend their time 00:27:43.539 --> 00:27:45.740 and their capital. Let's start with the most 00:27:45.740 --> 00:27:48.700 immediate effect, the effect on labor supply. 00:27:49.339 --> 00:27:52.440 Does high income tax discourage people from working? 00:27:53.099 --> 00:27:55.460 The research here has really evolved. Earlier 00:27:55.460 --> 00:27:58.299 studies were a bit inconclusive. They suggested 00:27:58.299 --> 00:28:00.920 a minimal effect on, say, the number of hours 00:28:00.920 --> 00:28:03.400 a full -time professional might work. But more 00:28:03.400 --> 00:28:05.539 recent, more nuanced studies, especially those 00:28:05.539 --> 00:28:08.019 that focus on high marginal rates and secondary 00:28:08.019 --> 00:28:10.700 earners, they indicate a large price elasticity 00:28:10.700 --> 00:28:13.359 of supply. That sounds very academic. What does 00:28:13.359 --> 00:28:15.819 a large price elasticity actually look like in 00:28:15.819 --> 00:28:18.339 a household? It looks like the spouse who decides 00:28:18.339 --> 00:28:21.099 not to enter the labor force. If that second 00:28:21.099 --> 00:28:23.480 earner's income immediately gets hit with a high 00:28:23.480 --> 00:28:26.319 tax bracket, say 35%, and then they have to subtract 00:28:26.319 --> 00:28:29.039 costs like child care. The net benefit of working 00:28:29.039 --> 00:28:32.079 might be tiny. It might be minimal or even zero. 00:28:32.559 --> 00:28:35.539 The tax burden reduces the ultimate reward for 00:28:35.539 --> 00:28:37.920 working and leads many people to decide that 00:28:37.920 --> 00:28:41.019 leisure or time spent on other activities is 00:28:41.019 --> 00:28:43.680 simply more valuable than that heavily taxed 00:28:43.680 --> 00:28:46.509 income. And that reduction in labor force participation 00:28:46.509 --> 00:28:49.470 is a real loss to the economy. And that reduction 00:28:49.470 --> 00:28:51.549 in activity, that leads directly to the concept 00:28:51.549 --> 00:28:54.529 of deadweight loss, or DWL, which sounds like 00:28:54.529 --> 00:28:57.170 something economists invented just to make taxation 00:28:57.170 --> 00:29:00.990 sound scary. DWL is a real and a critical concept. 00:29:01.250 --> 00:29:03.869 It represents the loss of economic activity that 00:29:03.869 --> 00:29:05.710 is not collected by the government as revenue. 00:29:05.890 --> 00:29:08.069 It's just lost entirely because of the friction 00:29:08.069 --> 00:29:10.589 of the tax. It's the higher cost that income 00:29:10.589 --> 00:29:13.049 tax imposes on labor and capital. So if someone 00:29:13.049 --> 00:29:15.289 decides not to work an extra 10 hours because 00:29:15.289 --> 00:29:17.950 the tax rate on that time is too high, the economic 00:29:17.950 --> 00:29:19.609 activity that would have been generated by those 00:29:19.609 --> 00:29:22.329 10 hours is the dead weight loss. Exactly. And 00:29:22.329 --> 00:29:24.710 that loss has a few components. There's the loss 00:29:24.710 --> 00:29:27.509 from productive labor or investment that just 00:29:27.509 --> 00:29:29.869 never happens. There's the distortion of economic 00:29:29.869 --> 00:29:32.390 choices, people investing in tax -advantaged 00:29:32.390 --> 00:29:34.470 areas that are maybe economically inefficient. 00:29:34.849 --> 00:29:37.009 And then there's the time and resources that 00:29:37.009 --> 00:29:39.279 are devoted to tax -avoiding behavior. So the 00:29:39.279 --> 00:29:42.539 act of trying to avoid the tax is itself a loss. 00:29:42.740 --> 00:29:46.000 Yes. Every hour, a highly paid lawyer spends 00:29:46.000 --> 00:29:49.599 engineering some loophole instead of, say, advising 00:29:49.599 --> 00:29:52.019 a company on a real commercial project is also 00:29:52.019 --> 00:29:54.359 considered a component of deadweight loss. And 00:29:54.359 --> 00:29:56.660 that fight against the tax system is constant. 00:29:56.859 --> 00:30:00.119 It leads to this vicious cycle of tax avoidance 00:30:00.119 --> 00:30:02.259 and complexity. This is the never -ending arms 00:30:02.259 --> 00:30:05.140 race between the state and the taxpayer. Clever 00:30:05.140 --> 00:30:07.259 tax avoidance strategies emerge legal methods 00:30:07.259 --> 00:30:09.880 that exploit loopholes. Lawmakers then respond 00:30:09.880 --> 00:30:13.220 by adding incredibly detailed, complex, and specific 00:30:13.220 --> 00:30:16.019 legislation that's intended to close those loopholes. 00:30:16.140 --> 00:30:18.279 And what's the result of this constant back and 00:30:18.279 --> 00:30:20.859 forth? The entire system just becomes labyrinthine. 00:30:21.220 --> 00:30:24.240 And the crushing consequence is that this complexity 00:30:24.240 --> 00:30:26.720 tends to disproportionately benefit large corporations 00:30:26.720 --> 00:30:29.500 and wealthy individuals. They are the only ones 00:30:29.500 --> 00:30:31.039 who could afford the sophisticated accounting, 00:30:31.319 --> 00:30:33.799 the legal advice, and the tax planning you need 00:30:33.799 --> 00:30:36.160 to find and use the loopholes. Which fundamentally 00:30:36.160 --> 00:30:38.339 challenges the whole progressive nature of the 00:30:38.339 --> 00:30:40.779 system that we defined back in Section 1. It 00:30:40.779 --> 00:30:43.299 does. While the progressive rates on paper suggest 00:30:43.299 --> 00:30:45.259 that high income earners pay the highest proportion, 00:30:45.579 --> 00:30:47.759 the complexity allows those same high income 00:30:47.759 --> 00:30:51.039 earners to manipulate their taxable income downward 00:30:51.039 --> 00:30:54.099 in ways that are just not available to a median 00:30:54.099 --> 00:30:57.559 wage earner who only has W -2 income. And that 00:30:57.559 --> 00:31:00.259 fuels inequality and political discontent. Let's 00:31:00.259 --> 00:31:02.440 move to a challenge that often goes unnoticed, 00:31:02.519 --> 00:31:05.119 working silently in the background. Bracket creep 00:31:05.119 --> 00:31:08.819 or fiscal drag. This is a quiet, systemic way 00:31:08.819 --> 00:31:11.619 that taxes rise without a single legislator ever 00:31:11.619 --> 00:31:13.799 casting a vote. Bracket creep is what happens 00:31:13.799 --> 00:31:16.059 when inflation pushes your nominal wages into 00:31:16.059 --> 00:31:19.059 higher tax brackets or just increases your effective 00:31:19.059 --> 00:31:21.660 average tax rate, even if your real purchasing 00:31:21.660 --> 00:31:23.940 power hasn't increased at all. Can you give us 00:31:23.940 --> 00:31:26.119 a concrete example of how this would work in 00:31:26.119 --> 00:31:28.980 a system that's not indexed for inflation? Sure. 00:31:29.259 --> 00:31:32.690 Imagine in country A. The 10 % tax bracket ends 00:31:32.690 --> 00:31:36.650 at $30 ,000. If inflation is 5%, a worker who 00:31:36.650 --> 00:31:39.609 earned $30 ,000 last year now has to earn $31 00:31:39.609 --> 00:31:42.730 ,500 just to buy the same stuff. Right, just 00:31:42.730 --> 00:31:47.130 to stand still. But that extra $1 ,500 now falls 00:31:47.130 --> 00:31:51.529 into the next tax bracket, say 20%. So the government's 00:31:51.529 --> 00:31:53.690 now collecting tax at a higher marginal rate 00:31:53.690 --> 00:31:56.009 on money that hasn't actually provided the worker 00:31:56.009 --> 00:31:58.960 with any real benefit. The worker now has less 00:31:58.960 --> 00:32:02.000 real disposable income because their tax burden 00:32:02.000 --> 00:32:04.380 rose automatically. So the government gets an 00:32:04.380 --> 00:32:08.299 unlegislated real tax hike and the taxpayer suffers 00:32:08.299 --> 00:32:10.220 a silent reduction in their standard of living. 00:32:10.400 --> 00:32:13.099 Precisely. To combat this, some countries have 00:32:13.099 --> 00:32:15.059 chosen to index their brackets and deductions. 00:32:15.220 --> 00:32:17.519 They're automatically adjusted upward each year 00:32:17.519 --> 00:32:19.960 based on the inflation rate, which prevents this 00:32:19.960 --> 00:32:22.740 fiscal drag. But a lot of countries choose not 00:32:22.740 --> 00:32:25.299 to because bracket creep is a politically convenient, 00:32:25.559 --> 00:32:27.880 stealthy source of additional government revenue. 00:32:28.180 --> 00:32:31.039 Let's pivot back to the global systems and look 00:32:31.039 --> 00:32:33.220 again at that distinction between territorial 00:32:33.220 --> 00:32:37.180 and residential systems. This choice really dictates 00:32:37.180 --> 00:32:39.680 how a country sees its engagement with the world. 00:32:40.019 --> 00:32:43.220 The territorial system is focused inward. Tax 00:32:43.220 --> 00:32:45.740 is imposed only on local income that's sourced 00:32:45.740 --> 00:32:48.740 inside the country. France, for its corporations, 00:32:48.980 --> 00:32:51.670 is a classic example. The policy choice here 00:32:51.670 --> 00:32:54.069 is to attract foreign capital by making it clear 00:32:54.069 --> 00:32:56.789 that profits you earn somewhere else won't be 00:32:56.789 --> 00:32:59.130 taxed locally. And the residential system used 00:32:59.130 --> 00:33:01.250 by the U .S. and Germany, that's the global model. 00:33:01.470 --> 00:33:03.910 It looks outward. Residents are taxed on their 00:33:03.910 --> 00:33:06.730 worldwide income. This system is philosophically 00:33:06.730 --> 00:33:09.029 based on the idea that citizenship or residence 00:33:09.029 --> 00:33:11.509 confers a benefit that you should pay for no 00:33:11.509 --> 00:33:13.880 matter where you earn the income. And the U .S. 00:33:13.900 --> 00:33:16.500 has that exceptional and highly complex rule 00:33:16.500 --> 00:33:19.019 regarding its citizens who live abroad. It's 00:33:19.019 --> 00:33:21.660 highly unusual. The U .S. is almost alone in 00:33:21.660 --> 00:33:24.079 taxing its non -resident citizens on their worldwide 00:33:24.079 --> 00:33:27.019 income based solely on citizenship. It doesn't 00:33:27.019 --> 00:33:28.819 matter how long they've lived abroad or if they've 00:33:28.819 --> 00:33:31.079 earned any U .S.-sourced income. That must create 00:33:31.079 --> 00:33:34.299 a huge compliance burden. A massive burden for 00:33:34.299 --> 00:33:37.240 Americans living overseas. And it requires specialized 00:33:37.240 --> 00:33:40.180 exclusions and treaties just to function at all. 00:33:40.640 --> 00:33:43.539 It's a major outlier in global tax policy. And 00:33:43.539 --> 00:33:45.519 we noted that countries will mix and match these 00:33:45.519 --> 00:33:48.220 systems, which shows there's no perfect universal 00:33:48.220 --> 00:33:50.440 solution. Absolutely. You might have a country 00:33:50.440 --> 00:33:52.599 like Brunei that taxes corporate income but not 00:33:52.599 --> 00:33:55.539 personal income, or Singapore, which separates 00:33:55.539 --> 00:33:58.220 its treatment. It uses a residential system for 00:33:58.220 --> 00:34:00.960 individuals, but a territorial one for corporations. 00:34:01.930 --> 00:34:04.569 The tapestry of global tax is determined by a 00:34:04.569 --> 00:34:07.390 country's unique economic goals. Whether they're 00:34:07.390 --> 00:34:10.329 trying to attract mobile wealth or fund a big 00:34:10.329 --> 00:34:12.809 social safety net. Exactly. Or encourage local 00:34:12.809 --> 00:34:15.389 investment. It's all a tradeoff. Finally, we 00:34:15.389 --> 00:34:17.369 turn to a subject of just radical difference 00:34:17.369 --> 00:34:21.030 and I think great controversy, transparency and 00:34:21.030 --> 00:34:23.429 public disclosure. This is a policy choice that 00:34:23.429 --> 00:34:25.750 fundamentally redefines the relationship between 00:34:25.750 --> 00:34:28.239 the state. and the citizen in countries like 00:34:28.239 --> 00:34:30.920 finland norway and sweden personal income tax 00:34:30.920 --> 00:34:33.059 filings including the person's income and the 00:34:33.059 --> 00:34:36.400 tax they paid are publicly disclosed so a citizen 00:34:36.400 --> 00:34:39.079 could genuinely look up the tax record of their 00:34:39.079 --> 00:34:42.440 neighbor or maybe the ceo of a major local company 00:34:42.829 --> 00:34:45.090 That's correct. In Sweden, this practice has 00:34:45.090 --> 00:34:47.730 been enshrined since 1905 with the annual publication 00:34:47.730 --> 00:34:50.690 of the tax ring Skalendern. The philosophy here 00:34:50.690 --> 00:34:53.329 is that radical transparency increases compliance, 00:34:53.730 --> 00:34:56.449 it holds authorities accountable, and it promotes 00:34:56.449 --> 00:34:59.329 a fairer social contract because wealth and contribution 00:34:59.329 --> 00:35:02.280 are visible to everyone. And this is in direct 00:35:02.280 --> 00:35:05.059 stark contrast to countries like the U .S., where 00:35:05.059 --> 00:35:08.179 tax information is considered the ultimate private 00:35:08.179 --> 00:35:11.420 financial detail. What are the potential downsides 00:35:11.420 --> 00:35:13.599 of that kind of radical transparency? Well, while 00:35:13.599 --> 00:35:15.400 it might increase compliance, it can also lead 00:35:15.400 --> 00:35:18.179 to social friction, jealousy, potential security 00:35:18.179 --> 00:35:21.460 issues. It's a fundamental choice. Does the public 00:35:21.460 --> 00:35:23.679 good of transparency outweigh the individual's 00:35:23.679 --> 00:35:26.139 right to financial privacy? And the Scandinavian 00:35:26.139 --> 00:35:29.099 nations decided yes. They decided yes. Most of 00:35:29.099 --> 00:35:31.219 the rest of the world, including you and our 00:35:31.219 --> 00:35:33.780 audience, have decided no. Hashtag tag outro. 00:35:34.340 --> 00:35:37.500 So to synthesize this huge deep dive, we can 00:35:37.500 --> 00:35:40.559 really return to that core distinction. The global 00:35:40.559 --> 00:35:43.139 structure of income tax is defined by the tension 00:35:43.139 --> 00:35:46.000 between the simple, locally focused territorial 00:35:46.000 --> 00:35:48.670 system. which is designed to attract external 00:35:48.670 --> 00:35:51.829 capital. And the complex, globally reaching residential 00:35:51.829 --> 00:35:54.429 system. And the complex residential system, which 00:35:54.429 --> 00:35:57.969 requires this massive international web of DTAs 00:35:57.969 --> 00:36:00.510 and foreign tax credits just to manage the global 00:36:00.510 --> 00:36:03.389 movement of people and money. And what endures 00:36:03.389 --> 00:36:06.210 through this entire history from 9CE China to 00:36:06.210 --> 00:36:08.869 modern Washington is the persistence of the system 00:36:08.869 --> 00:36:11.210 and the resistance to it. Whether the challenge 00:36:11.210 --> 00:36:13.829 is external like a war that requires new funding 00:36:13.829 --> 00:36:16.670 or internal like the constant pressure of bracket 00:36:16.670 --> 00:36:19.670 creep silently raising the tax income tax just 00:36:19.670 --> 00:36:22.409 adapts. It is a permanent fixture that's constantly 00:36:22.409 --> 00:36:24.449 trying to maintain its balance against the forces 00:36:24.449 --> 00:36:26.630 of avoidance and complexity. We saw that that 00:36:26.630 --> 00:36:29.429 first experiment in taxing net income under Emperor 00:36:29.429 --> 00:36:33.030 Wang Meng failed within 13 years because of popular 00:36:33.030 --> 00:36:36.170 unrest and the seizure of property. The modern 00:36:36.170 --> 00:36:37.989 state has solved some of those administrative 00:36:37.989 --> 00:36:41.070 problems, but that underlying social contract, 00:36:41.329 --> 00:36:43.789 the public's willingness to fund the government, 00:36:43.949 --> 00:36:46.670 that remains the system's most vulnerable point. 00:36:46.949 --> 00:36:49.349 Which leads us to our final provocative thought 00:36:49.349 --> 00:36:52.190 for you to consider. Reflect on that Scandinavian 00:36:52.190 --> 00:36:55.369 model of public disclosure. If you knew definitively 00:36:55.369 --> 00:36:57.610 what your peers and your competitors earned and 00:36:57.610 --> 00:37:00.409 paid, how would that knowledge change your personal 00:37:00.409 --> 00:37:03.429 decisions? Your decisions about work, compensation 00:37:03.429 --> 00:37:06.510 negotiation? your level of trust in your government? 00:37:07.030 --> 00:37:09.710 Would that radical transparency solve the complexity 00:37:09.710 --> 00:37:12.250 and avoidance problems we discussed? Or would 00:37:12.250 --> 00:37:14.789 it simply create new and perhaps deeper social 00:37:14.789 --> 00:37:17.329 frictions? It's a point of fundamental difference 00:37:17.329 --> 00:37:19.389 in civic approach to revenue, and it's one worth 00:37:19.389 --> 00:37:21.690 exploring on your own. A fascinating concept 00:37:21.690 --> 00:37:23.809 to mull over indeed. Thank you for joining us 00:37:23.809 --> 00:37:25.369 on the Deep Dive. We hope you feel thoroughly 00:37:25.369 --> 00:37:27.750 informed and armed with insight into this universal 00:37:27.750 --> 00:37:29.409 but very complicated mechanism.
