ALBANY -- Republican U.S. Senate challenger Wendy Long and her husband reported $1.24 million in total income and federal tax payments of more than $335,000 for 2011, according to a joint federal tax return the campaign released Friday.

Nearly all the income was from husband Arthur Long's partnership in the Manhattan-based law firm Davis Polk. Long, a Manhattan lawyer running against incumbent Sen. Kirsten Gillibrand (D-N.Y.), reported no wages for herself.

The Longs, who listed deductions for two children, paid $335,027.63 in federal taxes, and received a $27.63 federal tax refund. They gave $30,159 to unspecified charities and claimed $228,611 in itemized deductions.

The Longs paid $134,731 in New York State and local taxes and received a $768.91 state tax refund. Their combined state, federal and local tax bill was $470,527.

The couple also reported $31,799.60 in IRA distributions.

Gillibrand released five years of federal and state tax returns in July. She earned more than $165,000 in 2011 and paid nearly $39,000 in state and federal taxes, the returns show. In her first year in office in 2010, Gillibrand earned approximately $148,000 and paid more than $28,000 in state and federal taxes, according to the returns.

Gillibrand spokesman Glen Caplin didn't respond specifically to Long's tax information but said the senator "welcomes all efforts to increase transparency."

Caplin added, "After releasing personal tax returns dating back to 2005, [Gillibrand] led by example yet again earlier this year by becoming the first member of Congress in history to post personal tax returns for every year she's served in elected office directly on her own website for her constituents to see."

The two candidates are scheduled to face off in a debate at Skidmore College in Saratoga Springs on Oct. 17.

When Long this summer called on Gillibrand to release her taxes -- members of Congress aren't required to, and few do -- she vowed to release her own taxes but declined to say when.

A spokesman, David Catalfamo, didn't immediately respond to a request asking why Long released only a single year's returns.
