Do budget models agree the reconciliation bill would widen deficits?
Core argument: The Penn-Wharton Budget Model, Yale's Budget Lab, the Tax Foundation, and the Tax Policy Center all estimate the House-passed reconciliation bill delivers roughly $4.0tn in tax cuts over ten years, partially offset by about $1.5tn in spending cuts.
The Penn-Wharton Budget Model (PWBM), The Budget Lab (TBL) at Yale,The Tax Foundation (TF) and the Tax Policy Center (TPC) [produce projections that] are largely consistent with each other.They all show a tax cut of around $4.0 trillion over ten years, partially offset by spending cuts of about $1.5 trillion over the same time span. PWBM’s dynamic estimates are more pessimistic in the near term than those produced by the Tax Foundation. PWBM projects that the economic effects of the bill will widen the 10-year deficit effect from $2.8 trillion in its conventional forecast to $3.2 trillion, while the Tax Foundation expects higher growth from the bill’s tax provisions to narrow projected deficits by about $0.9 trillion compared to its conventional forecast. The models are in agreement that the overall effect of the legislation will be to widen future deficits rather substantially, even when growth is taken into account. Moreover, if those tax provisions in the bill which are now scheduled to expire in three to eight years were made permanent, the cost of the tax title would increase further.
