As the 2025 tax-and-spending law moved through Congress, the White House gave it a clean bill of fiscal health. "This bill does not add to the deficit," the press secretary said. "In fact, according to the Council of Economic Advisors, this bill will save $1.6 trillion." [1] The official scorekeeper of federal legislation reached the opposite conclusion, and not by a rounding error.
What the scorekeeper found
The Congressional Budget Office scored the final enacted law as adding $3.4 trillion to deficits over ten years, before counting the added interest on the borrowing. [2] The Committee for a Responsible Federal Budget, reading CBO's estimate of the House-passed version, put the increase in primary deficits at about $2.4 trillion, or close to $3 trillion once interest is included, enough to push federal debt from 100 percent of GDP to 124 percent by 2034. [3] Independent modelers landed in the same range, with the Penn-Wharton Budget Model estimating roughly $3.2 trillion. [1]

Where the 'saves $1.6 trillion' number comes from
The claim was not invented so much as half-counted. The $1.6 trillion is real: it is the bill's spending cuts. What the sentence leaves out is the other side of the ledger, roughly $3.8 trillion in revenue the law gives away by extending the 2017 tax cuts and stacking new ones on top. [1] Count only the cuts and ignore the giveaway, and a law that loses trillions can be dressed up as one that saves money. PolitiFact rated the claim False.
The baseline trick
The "won't add a penny" framing leans on what budget analysts call a current-policy baseline, which treats extending expiring tax cuts as free, on the theory that they were already in place. Under the standard scoring that Congress actually uses, extending them costs money, and the law increases deficits and the debt. [1] The choice of baseline is the difference between "saves $1.6 trillion" and "adds $3.4 trillion," and only one of them is the number the CBO reports.
THE BOTTOM LINE
- "Does not add to the deficit": False [1]
- CBO scores the final enacted law at a $3.4 trillion deficit increase over 10 years [2]
- The $1.6 trillion "savings" counts the spending cuts but ignores about $3.8 trillion in lost revenue [1]
There is a real debate about whether the tax cuts are worth their cost. That debate has to start from the cost. The official scorekeeper, the budget hawks, and the academic modelers all put it in the trillions, and saying the bill pays for itself does not make the bill pay for itself.
