Campaign committees are sometimes money makers, but when they are, they must pay taxes, as President Obama's campaign did with a $523,000 payment to the I.R.S.
Campaigns often carry large cash balances and can earn interest on their accounts - and some even invest campaign funds. A number of campaigns have developed large mailing lists of donors and rent out their lists to other like-minded candidates, PACs and political party committees. The income generated from interest, investing, and renting lists is taxable income. Obama for America, the campaign committee of President Barack Obama, reported it paid $523,000 on March 14, 2014, to the Internal Revenue Service for taxes.
