President Obama is making less money than he used to, though it's still a lot: He and wife, Michelle, reported income of $1.73 million last year, mostly from the books he's written, according to his 2010 tax return. That was down from the $5.5 million in 2009.
The president paid the government $453,770 in federal taxes, about a quarter of the income.
The White House released tax returns for the Obamas and for Vice President Biden and his wife on Monday, the deadline for Americans to file.
The president for the first time drew his full $400,000 salary in 2010, since in 2009 he didn't start drawing pay until after his inauguration in late January.
The first family's adjusted gross income for 2010 was $1.728 million. Their taxable income after deductions was $1.34 million.
The income for both years was mostly driven by royalties from books written earlier by Obama. They included his 1995 memoir "Dreams From My Father" and his 2006 political book, "The Audacity of Hope."
Obama also derived income from his new children's book, "Of Thee I Sing: A Letter to My Daughters," but he donated all proceeds to a charity benefiting children of slain and disabled soldiers, the White House said.
The president and first lady donated $245,075 -- about 14.2 percent of their adjusted gross income -- to 36 different charities. The largest was a contribution of $131,075 to the Fisher House Foundation, which provides humanitarian support to members of the United States Armed Forces and their families.
