As you know, Mitt paid 13.9% on his taxes in 2010. Under the tax plan espoused by VP candidate Paul Ryan, Mitt would have paid… somewhat less.

In 2010 — the only year we have seen a full return from him — Romney would have paid an effective tax rate of around 0.82 percent under the Ryan plan, rather than the 13.9 percent he actually did. How would someone with more than $21 million in taxable income pay so little? Well, the vast majority of Romney’s income came from capital gains, interest, and dividends. And Ryan wants to eliminate all taxes on capital gains, interest and dividends…

Romney did earn $593,996 in author and speaking fees in 2010 that would still be taxed under the Ryan plan. Just not much. Ryan would cut the top marginal tax rate from 35 to 25 percent and get rid of the Alternative Minimum Tax — saving Romney another $292,389 or so on his 2010 tax bill. Now, Romney would still owe self-employment taxes on his author and speaking fees, but that only amounts to $29,151. Add it all up, and Romney would have paid $177,650 out of a taxable income of $21,661,344, for a cool effective rate of 0.82 percent.
