Average Tax Rates for Married Couple with Two Incomes: 2009

The third in series of infographics I am designing to illustrate the average federal tax rate applied to different salaries. This time I am graphing the average tax rates for married couples filing a joint tax return but with 2 incomes (same salary for each). The difference between this graph and the couple with one income is that the the Social Security Tax cut off is now $213,600 (instead of $106,800), which increases their average SSN tax rate and their combined tax rates.

The income tax graph is created from the 2009 tax schedule for a couple filing jointly or qualifying widow(er):

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