U.S. Government Still Running Massive Deficit Despite Tariff Revenue

Despite the influx of tariff revenue, the federal government continues to run a massive budget deficit.

The December budget shortfall came in at $144.75 billion, a record for the month. That was 68 percent higher than December 2024.

However, looking at just one month gives a bit of a skewed picture. Calendar effects and delayed payments stemming from the government shutdown last year continue to muddle the accounting. Calendar effects pushed some January payments into December.

We get a better picture of the government’s fiscal trajectory when we look at the last three months (the first three months of fiscal 2026).

Looking at the three-month data, we find tariff receipts are modestly narrowing the budget gap. The deficit is down around 15 percent through the first three months of fiscal 2026 compared to the same period last year.

That may sound like great news until you realize that even with the modest decline, the three-month deficit is still $602.38 billion.

Has Tariff Revenue Plateaued?

Through the first three months of fiscal 2026, the U.S. Treasury collected $90 billion in tariffs. That compares to $20.8 billion through the same period in fiscal 2025. However, it appears tariff revenue may have peaked.

Customs receipts dropped slightly to $27.9 billion in December. That compares to $30.76 billion in November, which was down modestly from a record $31.4 billion in October.

In total, the Treasury collected $484.38 billion in December, a 6.6 percent increase over last year. Through the first three months of fiscal ’26, the federal government has collected $1.23 trillion, up 13 percent over the first three months of fiscal 2025.

It should be clear that claims that the federal government is going to use tariff revenue to pay a “dividend” to poor and middle-class taxpayers and pay down the national debt are nothing but political rhetoric. Math is the great enemy of this ambitious plan. Even with triple-digit percent increases in tariff revenue, the federal government is still running a huge deficit.
