Reader Response: How Much Americans Actually Pay in Taxes, Part II

Yesterday we posted Congressional Budget Office data on the effective average tax rates Americans pay at the federal level.

In response, many readers wrote in asking how much Americans pay in state and local taxes. After all, the C.B.O. numbers included federal tax revenues only, and most Americans also pay taxes at the state and local levels, too.

The answer to this question depends largely on the way you measure tax revenues and incomes (and there are disputes about the best numbers to use), but here are a couple of approaches.

The Tax Policy Center has data on what percentage of their personal incomes Americans pay in state and local taxes. Nationwide, this averages 10.9 percent, with a low of 8.66 percent in New Hampshire and a high of 15.04 percent in Wyoming.

The way these state and local tax rates were calculated is slightly different from the way the C.B.O.’s federal tax rates were calculated, however. Here’s one way to approximate the total amount Americans paid in taxes to governments, at any level, versus the national income brought in by all Americans (a measure suggested by Jon Bakija, an economics professor at Williams):

The green line represents the total amount of federal, state and local tax revenues for a given year, divided by the national income for that year. By this measure, in 2007 the average American paid 32.15 percent of income in taxes to the government (10.85 percent at the state and local level, and 21.3 percent at the federal level).

Unfortunately, I have not yet found a quintile breakdown for effective tax rates that includes state and local taxes. If you can suggest a good resource for this data, please let me know.

Speaking of quintiles, another common reader question was about how much you needed to earn to fall into a particular income quintile. Here are the numbers for average pre-tax incomes in each quintile, going back to 1979. (Remember: These are average numbers, not median numbers or the cut-offs between percentiles.)"
