On their 2006 tax return, Obama and his wife, Michelle, earned over $991,000 in 2006 and paid $277,431 on the income.
More than half of the couple's income is a direct royalty from Obama's books--nearly $507,000: The Audacity of Hope and Dreams From My Father. In 2005, Obama earned over $1,210,000 from royalties.
The Obamas earned nearly $431,000 in wages in 2006. The Senator's salary was $165,000.
The couple also earned more than $51,000 from Treehouse Foods, an Illinois-based food manufacturer where Michelle Obama served on the Treehouse board.
Before 2005, the couple had more modest incomes. Between 2000 and 2004, they earned between $207,647 and $275,123 a year.
