The numbers: The U.S. ran a $205 billion deficit in November, a jump of $66 billion, or 48%, from the same month a year ago, the Treasury Department announced Thursday.

November’s worse budget picture is mostly due to a $44 billion calendar-related shift in when payments got sent out.

What happened: The U.S. took in 1% less in revenue, mostly as individual withheld and FICA taxes fell by 2%, while corporate taxes fell by 23%. Customs duties doubled to $6 billion, on the impact of rising tariffs.

The 18% jump in spending came on a 35% jump in Medicare payments, a 27% increase in defense spending and a 74% increase in Veterans Affairs costs.

For the fiscal year as a whole, the deficit has grown by 51% to $305 billion. The Treasury Department says that adjusted for timing-related transactions, the deficit would have been $270 billion over the last two months compared to $250 billion during the same period the prior year, with tax revenue up by 1% but spending up by 4%.

The big picture: The budget picture is deteriorating as the U.S. taxes individuals and companies less and spends more, mostly on defense and benefit payments to an aging population. A growing economy is softening the blow, however, and it’s unclear at this point whether the annual deficit will top $1 trillion this year.

The Congressional Budget Office on Thursday published a list of 121 options to reduce the deficit, including establishing caps on federal spending on Medicaid, reducing the Department of Defense’s budget, and increasing payroll taxes.
