Tax Bill Would Add $3.3 Trillion to US Deficits, CBO Says

The Senate version of President Donald Trump’s tax and spending measure would add nearly $3.3 trillion to US deficits over a decade, according to a new estimate from the nonpartisan Congressional Budget Office.

The CBO score for the so-called One Big Beautiful Bill reflects a $4.5 trillion decrease in revenues and a $1.2 trillion decrease in spending through 2034, relative to a current law baseline.
