US National Debt Reaches 100% of GDP as Tax Cuts Drive Long-Term Borrowing

The total national debt in the United States has reached $32 trillion, pushing the debt-to-GDP ratio to 100%. According to data from the Congressional Budget Office analyzed by the Center for American Progress, successive rounds of tax cuts enacted over the past quarter-century have contributed more than $10 trillion to this borrowing burden. Without these legislative reductions, the debt-to-GDP ratio would otherwise be on a downward trajectory.

While federal spending outside of major emergencies like the 2009 recovery package and COVID-19 stimulus has remained relatively flat relative to a growing economy, federal revenue has repeatedly been reduced. Studies from the Tax Foundation note that historical tax packages, ranging from Ronald Reagan's 1981 reductions to Donald Trump's 2025 legislation making permanent his 2017 tax cuts, have continually outpaced revenue collection relative to gross domestic product.

Lawmakers and incoming majorities in Congress now face difficult fiscal arithmetic. Independent projections from the Congressional Budget Office estimate that growing deficits driven by these ongoing tax policies and higher interest rates will push public debt to 116% of GDP by the end of 2034.

Rising borrowing costs mean that new debt resulting from tax cuts or spending creates a much heavier burden today than it did fifteen or twenty years ago.

What to watch next: Future legislative battles over expiring provisions and potential policy adjustments aimed at addressing the widening gap between federal revenues and spending.
