Monthly Treasury Statement

What it reports

The Monthly Treasury Statement is the Treasury’s official record of the government’s finances for one month: receipts by source, outlays by agency and function, and the deficit or surplus. It is the primary source for the fiscal-year-to-date figures, and it appears within about two weeks of the month it covers.

Why it is the reference

It is authoritative in a way projections are not. When a headline says the deficit reached a particular level and the figure is not an estimate, it almost certainly comes from this statement. It also breaks down the composition of revenue and spending, which is what makes it useful for a question like how much of the budget is borrowed.

What to watch in it

Two things. The monthly figure alone is noisy, because tax and payment dates fall unevenly, so the year-to-date column is the meaningful one. And receipts and outlays are gross rather than net, so a month with heavy collections and heavy payments can look large on both sides while the deficit barely moves.
