Underneath the Noise, Budget Deficit Progress!

Over the past two and one-half decades the federal government has buried taxpayers under a mountain of debt, now approaching $38 trillion.

During this time the key problem has been spending, not a lack of tax revenue. Over the past 25 years, taxes have remained relatively stable as a share of GDP, while spending continued to rise. We estimate that spending was 23.2% of GDP in the year ending September 30 (Fiscal Year 2025) versus 17.7% in 2000. In other words, the reason we have a debt problem is because we have a spending problem.

That’s the bad news, and it means policymakers still have a very long way to go before we can claim our fiscal house is in order. But just because the overall budget picture remains bleak doesn’t mean we shouldn’t recognize improvements when they happen, and there is some progress.

The Congressional Budget Office recently estimated that budget deficit for the year that that ended on September 30 (FY 2025) came in at $1.809 trillion, slightly smaller than the $1.817 trillion of FY 2024. Although that’s only an improvement of $8 billion in dollar terms, there are reasons for at least some modest hope on the deficit.

First, we project that nominal GDP grew 4.8% in FY 2025, which means that even if the deficit remained roughly the same in dollar terms, it declined relative to GDP. After clocking in at 6.3% of GDP in FY 2024, it looks like it was 6.0% in FY 2025. That may seem like only a minor improvement, just 0.3 percentage points of GDP, but it’s a shift from the expansion of the deficit in the prior two years. It’s movement in the right direction.

Second, the decline in the deficit this past year would have been larger were it not for a calendar-related issue. In particular, two years ago (in 2023) October 1st fell on a Sunday and so $72 billion in federal payments (spending) that normally would have been made that day were instead made on Friday September 29, 2023. That shift changed the budget math because September 29 was still in FY 2023. This artificially held down official spending in FY 2024 making the deficit appear smaller than it really was. In addition, due to natural disasters in 2023, some taxpayers were allowed to postpone tax payments. This boosted revenue in FY 2024 by about $70 billion. In other words, the actual reduction in the deficit for FY 2025 was really closer to $150 billion, not $8 billion.
