Rising tax receipts led the United States to run a budget surplus in September, leaving the federal deficit for the full fiscal year at its lowest level since 2008, Treasury Department data showed on Wednesday.
The federal government took in $75.1 billion more last month than it spent, leaving the deficit for the fiscal year, which runs from October to September, at $680 billion.
Washington took in about 80 cents for every dollar it spent over the year.

The deficit widened sharply during the 2007-09 recession, which hit tax revenues and increased payments for unemployment benefits. But a strengthening economy, tax hikes and cuts to federal spending nearly halved the deficit in fiscal year 2013.
The Treasury said in a statement that higher tax receipts accounted for about 4/5 of the deficit's reduction.
