Republican presidential candidate Mitt Romney reportedly paid about $3 million in federal income taxes in 2010 on income of $21.7 million.
Romney's tax returns show most of his income came from investments. He also gave nearly $3 million combined to charitable causes and the Mormon Church, helping reduce his effective tax rate to less than 14%.
The former Massachusetts governor agreed to make public his 2010 federal tax returns, and his estimates for 2011, after opponents on both the left and right charged that he was hiding his income and assets. The issue has dogged his campaign in recent weeks and contributed to his loss to Newt Gingrich in Saturday's South Carolina primary.
Gingrich and his wife, Callista, paid $994,708 in federal taxes on gross income of $3,142,066 in 2010, according to copies of the couple's return. The 31.5% tax rate paid by the Gingriches is more than double the amount that Romney reportedly paid on his much larger income.
