Federal agency
Department of the Treasury
Collects the government’s revenue and pays the interest on its debt. Treasury’s outlays are dominated by that interest, which is why they have grown far faster than anything the department does with its own staff.

Spending history
Department of the Treasury paid out $8.5 billion in FY 1962 and $1.46 trillion in FY 2025 — a 172-fold increase in nominal terms. These are current dollars, not adjusted for inflation, so across 63 years the nominal change substantially overstates the real one. The share-of-budget figure below is the inflation-neutral way to read the same series.
Its highest year in this series was FY 2021, at $1.63 trillion, and over the last decade its outlays have changed by +200.4%.

Read as a share of the federal budget, the same series says something the nominal one cannot. A share is immune to inflation and to the growth of the budget itself, so it answers the question people usually mean when they ask whether an agency has grown: did it take a larger or smaller slice than it used to?

Staffing
OMB reports this department by name in its staffing table, so its headcount can be read directly rather than inferred. It employed the equivalent of 102,000 full-time civilian staff in FY 1981 and 111,000 in FY 2025 — +8.8%. These are full-time equivalents, not headcounts, and they exclude contractors and anyone in uniform.

The years that moved the line
A sixty-year spending chart is mostly gradual with a few sharp steps, and the steps are the interesting part. These are the largest single-year changes in Department of the Treasury’s outlays, ranked by size in dollars rather than by percentage: the early years involve small enough numbers that a percentage ranking would surface nothing but the 1960s.
| Fiscal year | From | To | Change |
|---|---|---|---|
| 2021 | $1.15 trillion | $1.63 trillion | +$482.0 billion (+41.9%) |
| 2022 | $1.63 trillion | $1.16 trillion | −$471.5 billion (−28.9%) |
| 2020 | $689.5 billion | $1.15 trillion | +$462.2 billion (+67.0%) |
Decade by decade
Averaging each decade smooths out the single-year spikes and shows the level the agency actually settled at. Decades with fewer than five years of data are left out rather than averaged, because a three-year average sitting beside a ten-year one looks like the same statistic and is not.
| Decade | Average annual outlays | Years averaged |
|---|---|---|
| 1960s | $11.8 billion | 8 |
| 1970s | $37.8 billion | 10 |
| 1980s | $148.0 billion | 10 |
| 1990s | $328.3 billion | 10 |
| 2000s | $451.0 billion | 10 |
| 2010s | $517.1 billion | 10 |
| 2020s | $1.31 trillion | 6 |

Common questions
What is the Department of the Treasury's budget?
Department of the Treasury paid out $1.46 trillion in FY 2025, which was 20.8% of all federal spending that year. That is outlays — money actually paid out — rather than an appropriation, and it is in current dollars, not adjusted for inflation. Treasury outlays are mostly interest on the federal debt, not the cost of running the department. The IRS is roughly nine in ten Treasury employees but a small share of Treasury spending.
How many people work at the Department of the Treasury?
OMB reports the equivalent of 111,000 full-time civilian staff in FY 2025. That is a full-time-equivalent count of work-years rather than a headcount, and it excludes contractors.
When did Department of the Treasury spending change the most?
Its largest single-year move was FY 2021, when outlays went from $1.15 trillion to $1.63 trillion — a change of $482.0 billion (+41.9%).
Where does this data come from?
The spending series is OMB Historical Table 4.1, published annually with the President's Budget, and the current-year figures are the agency’s own reports to USAspending.gov. Every figure is checked against the source table's own internal totals before it is published here; nothing is estimated or interpolated.
Sources and methods
Every figure on this page comes from one of the datasets below and nowhere else. Nothing is estimated, interpolated or carried over from a previous edition. Where two sources measure something similar, they are reported separately rather than combined, because they are not measuring the same thing.

Outlays are money actually paid out in a fiscal year, in millions of current (nominal) dollars — not appropriations, and not adjusted for inflation. Some rows are net of offsetting receipts and can be negative.

Reported by agencies under the DATA Act and updated within the fiscal year, so a current-year figure is partial by definition. Budgetary resources include unobligated balances carried in from prior years, which is why they exceed the year’s appropriation.
