My former intern, Hiwa Alaghebandian, has just narrated a new Economics 101 video about the cost of the tax code. I won’t spoil the surprise by giving the details, but you if you’re not angry now, you will be after watching.

In the video, Ms. Alaghebandian notes that a study from 1996 (back when the tax code was not nearly as complex) estimated that a flat tax would reduce the compliance burden of the income tax by 94 percent. In my video on the flat tax, I mostly focused on how a single-rate, consumption-base system would boost growth and competitiveness, but simplicity also would be a remarkable achievement. Not only would real tax reform reduce compliance costs by hundreds of billions of dollars, it would also put a big dent in the corrupt practice of distorting economic choices with deductions, exemptions, credits, preferences, shelters, and other loopholes. That’s a profitable game for politicians and lobbyists, but the rest of us pay the price because the tax code is even more of a nightmare.

There is also an under-appreciated connection between simplicity and fairness. My colleague Will Wilkinson sagely observed that “…the more power the government has to pick winners and losers, the more power rich people will have relative to poor people.” The tax code is a good example. Many leftists want the tax system to penalize success with high tax rates. I’ve explained why this is economically misguided in a video on class-warfare tax policy, but it’s also worth pointing out that a simple and fair tax system like the flat tax makes it much more difficult for the well-connected to take advantage of complexity. Simply stated, the tax system should not punish the rich with high rates (notwithstanding the neurotic views of self-loathing trust-fund heirs), and it shouldn’t reward them with special deals.

The good news is that we know the policies that will fix the current system. The bad news is that politicians keep making the system worse. Putting the IRS in charge of enforcing key parts of Obamacare is just the latest example of why America needs a tax revolt.
