Yes, 47% owe no federal income tax -- but look closer

But the picture starts to change when you look not just at income taxes but at all taxes. This average household would have paid 0.8 percent of its income in corporate taxes (through the stocks it owned), 0.9 percent in gas and other federal excise taxes, and 9.5 percent in payroll taxes. Add these up, and the family’s total federal tax rate was 14.2 percent.

I realize that it’s possible to argue that payroll taxes should be excluded from the discussion because they pay for benefits — Social Security and Medicare — that people receive on the back end. But that argument doesn’t seem very persuasive.

Why? People do not receive benefits equal to the payroll taxes they paid. Those who die at age 70 will receive much less in Social Security and Medicare than they paid in taxes. Those who die at 95 will probably get much more…

If anything, the government numbers I’m using here exaggerate how much of the tax burden falls on the wealthy. These numbers fail to account for the income that is hidden from tax collectors — a practice, research shows, that is more common among affluent families. “Because higher-income people are understating their income,” Joel Slemrod, a tax scholar at the University of Michigan, says, “We’ve been overstating their average tax rates.”
