Does the tax bill add less debt than campaign proposals suggested?
Core argument: The Committee for a Responsible Federal Budget estimates the passed bill adds $3.1tn to debt relative to the current-law baseline, versus its late-October 2024 central projections of $7.8tn for the Trump agenda and $4tn for the Harris agenda in 2026–2035.
Most estimates of the total “cost” of the proposed legislation start from the absurd baseline that individual and business taxes would have been allowed to rise sharply in 2026 as the TCJA expired. That was never particularly likely. The main surprise, to the extent that there was one, was the severity of the spending cuts, although some of them may be moderated by the Senate. In fact, according to the Committee for a Responsible Federal Budget (CRFB), the current budget plan adds far less to the debt stock relative to the “current law” baseline over the next ten years than they had expected based on pre-election campaign promises. The CRFB’s “central” projection as of the end of October 2024 was that the Harris agenda would generate additional borrowing of $4 trillion in 2026-2035 relative to “current law” and that the Trump agenda would generate $7.8 trillion in extra debt. Their current estimate of the bill just passed is that it would add only $3.1 trillion in incremental debt. Add in reasonable estimates of the revenue impact of tariffs and it is possible that the new budget could lead to almost no incremental increase in federal debt issuance compared to the “current law” baseline!"
