CBO estimates that comes out to $125 billion less than the $1.1 trillion deficit incurred through July 2011.
Receipts in the first 10 months of fiscal 2012 totaled $2 trillion, $114 billion more than those in the same period last year, CBO says.
Individual income tax receipts grew 4 percent to $37 billion and net receipts from corporate income taxes grew 30 percent to $42 billion, with withholdings up 3 percent.
Non-withheld payments went up 4 percent to $11 billion, but CBO added the tax receipt gains were offset by a one percent increase in refunds.
Through July, CBO estimates total outlays of $3 billion, adding the office made adjustments for costs of the Troubled Asset Relief Program and other credit activities.
