WASHINGTON - US federal government registered a budget deficit of $203.5 billion in February, the Department of Treasury figures revealed on Wednesday.

The federal government raked in a revenue of $122.8 billion in February, up 19 percent from the level of February 2012. It registered outlays of $326.4 billion, down 2.6 percent from February 2012, said the department.

The budget gap for the first five months of the 2013 fiscal year, which began on October 1, 2012, totaled $494 billion, down 15 percent from $581 billion in the first five months of 2012 fiscal year.
