Anyone know a source for the average effective personal income tax rate for the US. By state also would be great.

Definition: average effective income tax rate = (Total income tax collected)/(Total income earned)

Possibly a source for the data to do the calculation.

  • $\begingroup$ What you defined (total income tax collected/total income) is the average effective tax rate, not the marginal rate. $\endgroup$ – dismalscience Nov 18 '15 at 18:20
  • $\begingroup$ @dismalscience, you are correct. $\endgroup$ – Vincent Nov 18 '15 at 18:29

For a lot of things, including average effective (Federal) tax rates, the Urban Institute/Brookings Institution Tax Policy Center is a great place to start. Look at the table that reads "Average Individual Income Tax Rate," as the first one also includes payroll, excise, and corporate taxes.

  • $\begingroup$ This table almost has it, to bad they did not include to total effective. taxpolicycenter.org/taxfacts/displayafact.cfm?Docid=366 I am really only looking for an estimate, looks like it might be about 5-6% $\endgroup$ – Vincent Nov 18 '15 at 18:35
  • $\begingroup$ Check the "all quintiles" column of the table in the link I provided if you want the average of effective rates across everyone in the US. $\endgroup$ – dismalscience Nov 18 '15 at 18:38
  • $\begingroup$ ok so about 8.4 for 2011. Thanks a bunch! $\endgroup$ – Vincent Nov 18 '15 at 18:42
