As a portion of the economy, the budget deficit stood at 10 percent, the highest since World War II, according to government data released Friday.
For 2009, the government collected $2.10 trillion in revenues, a 16.6 percent drop from 2008. The plunge reflected declining income tax collections as millions of Americans lost their jobs or saw their wages cut. Corporate taxes also plummeted as the recession squeezed companies' profit margins.
Government spending last year jumped to $3.52 trillion, up 18.2 percent over 2008. The $700 billion financial bailout fund and increased spending and tax relief from the $787 billion economic stimulus program that Obama pushed through Congress in February drove the increase.
For September, a month when the government usually records surpluses, the deficit totaled $46.6 billion. That's a sharp contrast to the $45.7 billion surplus in September 2008, the last time the government's books were in the black.
