How much debt would the House-passed tax and spending bill add?
Core argument: CBO estimates the House-passed OBBBA would add more than $2.4 trillion to primary deficits over 10 years and, including interest, nearly $3.0 trillion to debt through 2034, or roughly $5.0 trillion if temporary provisions are made permanent.
CBO released an updated cost estimate for the House-passed OBBBA, projecting the bill would add over $2.4T to primary deficits over 10 years. Review the bill's specific cost estimates here. After interest costs on the new debt, CBO estimates that by FY2034 the bill would: increase debt by nearly $3T, or roughly $5T if made permanent; increase the deficit to 7% of GDP by 2026; double interest costs between 2024 and 2034 to $1.8T (4.2% of GDP); increase debt from 100% of GDP today to 124% of GDP by 2034, 129% of GDP if made permanent, and 133% if interest rates remain high. With interest, the bill would add nearly $3.0T to the debt through 2034 – or $5.0 trillion if various temporary provisions are made permanent. If rates remain at current levels (10-year Treasuries at 4.5%) then interest costs would climb further to $2.1T (5.1% of GDP) in 2034. OBBBA would increase the deficit to 7.0% of GDP by 2026, compared to a current law projected level of 5.5%.
