A press release on the Chairman's mark of the House Appropriations Committee's Labor-HHS appropriations bill that would fund Social Security's administrative budget indicates that the agency's budget for fiscal year (FY) 2013, which begins on October 1, 2012, would be $10.7 billion, $287 million below FY 2012. This bill is to be marked up in subcommittee tomorrow.
The Senate Appropriations Committee has already reported out its version of the Labor-HHS Appropriations bill and it provides $11.736 billion for Social Security's administrative budget, which was described as a $290 million increase over FY 2012.
Note that the difference in the amounts appropriated between the two bills is in excess of $1 billion yet if you add the $287 million decrease of the House Bill to the $290 million increase of the Senate bill you get a total difference between the two bills of $577 million. This is an excellent example of how bizarre and confusing the appropriations process is. I have no idea what accounts for the other $500 million of difference between the two bills.
