What’s in the New Tax Legislation?

Legislation signed into law on July 4, 2025, commonly called the One Big Beautiful Bill Act (OBBBA), fundamentally changed the federal tax and spending landscape. The law is so broad that this report can only summarize some key provisions that affect individuals and business owners.



2017 provisions made permanent

The OBBBA makes permanent most of the 2017 Tax Cuts and Jobs Act (TCJA) tax provisions that were set to expire this year.

Adding to the deficit

The nonpartisan Congressional Budget Office (CBO) estimated that the OBBBA will add $3.4 trillion to the budget deficit over the next decade. This includes a decrease in federal tax revenue of $4.5 trillion partially reduced by a decrease in direct spending of $1.1 trillion, primarily in reduced support for Medicaid, Affordable Care Act health plans, food stamps, education, and green energy. The estimate begins with the CBO budget baseline of January 2025, which assumed that all provisions of the 2017 TCJA that were scheduled to sunset — some of which had bipartisan support — would be allowed to expire.1

By any measure, the law is likely to add significantly to the deficit, increasing interest payments on the national debt. It remains to be seen how this added fiscal burden, along with economic stimulus through new tax breaks and reduced federal spending on social and environmental programs, will impact the U.S. economy.
