The federal government ran a budget deficit of roughly $750 billion for the first 11 months of fiscal year 2013, CBO estimates—a reduction of more than $400 billion from the shortfall recorded for the same period last year. Revenues have risen significantly, accounting for more than two-thirds of the decline in the deficit. The deficit for all of fiscal year 2013 is expected to be smaller than the 11-month figure, as revenues are likely to outpace outlays in September.

Receipts for the first 11 months of fiscal year 2013 totaled $2,472 billion, CBO estimates—$284 billion more than receipts for the same period last year.

Taxes withheld from workers’ paychecks rose by $160 billion (or 10 percent), mainly because of the expiration of the payroll tax cut in January 2013, higher wages and salaries, and increases (beginning in January) in tax rates for income above certain thresholds.
Nonwithheld taxes rose by $91 billion (or 27 percent). About three-fourths of that increase occurred during the tax-filing season (February through April), mainly because final payments for the 2012 tax year were much larger than their counterparts last year. Some of the growth in nonwithheld receipts also reflects an increase in estimated payments for the current tax year (made in the spring and the summer) and some payments made at other times for the 2012 tax year (such as the quarterly payments made in January 2013). The large percentage increase—53 percent—in other receipts of individual income and social insurance taxes (which are net of refunds) occurred because last year’s refunds offset much more of the payments than this year’s have.
The next quarterly estimated payments by individuals and most corporations are due in mid-September.
Outlays for the first 11 months of fiscal year 2013 were $127 billion less than spending during the same period last year, CBO estimates. Adjusted for shifts in the timing of certain payments and collections, mostly because the scheduled dates for some payments fell on a weekend, that decrease amounts to $129 billion, or 4 percent.

Outlays for several major programs or categories of spending were less than those during the first 11 months of last year:
Increases in spending for some other major programs during the first 11 months of fiscal year 2013 partially offset those declines:
The federal government realized a deficit of $146 billion in August 2013, CBO estimates, in contrast with the $191 billion deficit incurred in the same month last year—a difference of $45 billion. But that decrease was affected by shifts in the timing of certain payments and collections, which occurred mostly because the scheduled dates for some payments fell on a weekend or a holiday. The first day of September fell on a weekend in both years, and September 3 (the payment date for some Social Security benefits) was Labor Day, so certain payments that ordinarily would have been made in September were instead made earlier, increasing outlays by about $58 billion in August 2012 and by $35 billion in August 2013. Adjusted for those shifts, the reduction in the deficit for August shrinks to $21 billion.

CBO estimates that receipts in August totaled $185 billion—$6 billion (or 3 percent) more than those in the same month last year:
Total spending in August 2013 was $331 billion, CBO estimates—$39 billion less than outlays in the same month in 2012. However, outlays would have declined by $15 billion if not for the effects of timing shifts. (The month-over-month changes presented below reflect adjustments to account for those shifts.) The largest changes in outlays from amounts in August a year ago were these:
The Treasury Department reported a deficit of $98 billion for July, about $2 billion more than CBO estimated on the basis of the Daily Treasury Statements.
