She made more than I do both years. In fact, in 2006 she made more than I will likely make in my lifetime.
Not adjusted for inflation, natch.
Her marginal tax rates were 27.1% and 28.8% in 2007 and 2006 respectively.
Her marginal tax rates are lower than her husband's, which according to his press release were 32.6% and 33.8% respectively. Here's the direct quote about his taxes:
For 2006, Senator McCain paid $72,771 in federal income, alternative minimum, and self-employment taxes (LINES 57 and 58) on taxable income of $215,304 (LINE 43), which is a 33.8% tax rate.
For 2007, Senator McCain paid $84,460 in federal income, alternative minimum, and self-employment taxes (LINES 57 and 58) on taxable income of $258,800 (LINE 43), which is a 32.6% tax rate.
It's kind of crazy that John pays taxes at a higher rate than his wife.
What do you suppose will happen to Cindy's taxes under John McCain's tax plan? She'll pay even less taxes than she's paying now. John might pay more or less taxes under Obama's plan, depending on the year.
I couldn't find the exact figures for McCain's tax plan, but I did find this link suggesting that Cindy will get a 4.4% decrease in taxes under John's plan, while she will see a 11.5% increase under Obama's.
