How much additional revenue can higher taxes on the rich raise?
Core argument: Estimates of the revenue-maximizing top tax rate tend to fall in the range of 70 to 80 percent, well above the federal maximum of 37 percent, though state and local taxes raise many high earners' effective marginal rate to roughly 50 percent.
Very high marginal tax rates create problematic incentives. Conservatives emphasize how taxes reduce the incentive to work and create wealth; this effect is surely overrated, but it does exist. More important, high tax rates encourage extraordinary efforts to avoid taxes (which is legal) or evade them (which isn’t). Estimates of the revenue-maximizing top tax rate tend to be in the range of 70 percent to 80 percent, well above the federal maximum of 37 percent — but bear in mind that many high earners also face state and local taxes that raise their effective marginal rate to something like 50 percent. So, the amount of additional revenue we can raise from taxing the rich, while substantial, is considerably less than their remaining untaxed income.
