“Tariff revenue is going to wipe out the entire federal deficit eventually.”

Multiple speeches characterizing tariff revenue trajectory

The math makes this impossible. Tariffs raised $195 billion in fiscal year 2025, while the federal deficit that year was $1.78 trillion. Tariff revenue would have to roughly nine times its record level, with no offsetting economic damage, just to close the gap. Trump's own administration concedes there is no plausible path there.

The deficit is heading up, not toward zero. The Congressional Budget Office projects the FY2026 deficit at roughly $1.9 trillion, higher than FY2025 and about $140 billion above what CBO projected before Trump's policies took effect. Tariff revenue is rising, but it is being swamped by spending and the cost of the 2025 tax law.

Worse, much of the tariff revenue may not even survive. Courts have ruled key Trump tariffs illegal, and the Committee for a Responsible Federal Budget estimates that roughly $90 billion of the $195 billion collected could have to be refunded if the Supreme Court upholds the ruling, cutting the revenue Trump claims will erase the deficit nearly in half.
