The first of series of infographics I am designing to illustrate the actual federal tax rate applied to different salaries. I want to show how the marginal income tax rates + social security and medicare taxes combine together for a single taxpayer up to $400,000. (This graphic does not including payroll tax or any taxes on capital gains. Those taxes will be investigated later.)

A little background about this data. If you take a look at your W-2 form you can see that there are 3 different taxes applied to salaries and wages:

The income tax graph is created from the 2009 tax schedule for a single taxpayer:

which you can find from the IRS Tax Tables here while the information about the social security and medicare tax can be found here.

I found a Federal Reserve article that analyzed the change in Average Hourly Earnings for production and nonsupervisory workers. After adjusting for inflation using the Personal consumption expenditures (PCE) {instead of the Consumer Price Index-Urban Wage Earners and Clerical Workers (CPI-W)} and including an estimate for worker’s benefits, the author concluded that workers’ hourly earnings (wages plus benefits) actually increased by 16% over 30 years (1975-2005) rather than decreased. Here, I graphed the full history, 1964-2006, but used the approach laid out in the article to show the effect of inflation and benefits. BTW, if you earned $16.76 an hour in 2006 that gave you an annual income of $33,520 (assuming you worked full-time).
