Summary
The Tax Cuts and Jobs Act (TCJA), also known as the Trump Tax Cuts, was a landmark U.S. budget reconciliation law enacted in 2017 that significantly reformed the Internal Revenue Code. It primarily reduced corporate and individual tax rates, increased the standard deduction and family tax credits, while limiting certain itemized deductions like the state and local tax (SALT) deduction. Although many individual tax cuts were initially set to expire in 2025 and business cuts in 2028, the "One Big Beautiful Bill Act" passed in 2025 made most of these provisions permanent. This extension has raised economic concerns, with the Congressional Budget Office projecting an additional $4.6 trillion to the national debt over ten years, and studies indicating the TCJA disproportionately benefited the affluent and had a more modest impact on economic growth and median wages than anticipated.

The Tax Cuts and Jobs Act, Pub. L. 115–97 (text) (PDF), is a budget reconciliation law that amended the Internal Revenue Code of 1986. The legislation is commonly referred to in media as the Trump Tax Cuts. Major elements of the changes include reducing tax rates for corporations and individuals, increasing the standard deduction and family tax credits, eliminating personal exemptions and making it less beneficial to itemize deductions, limiting deductions for state and local income taxes and property taxes, further limiting the mortgage interest deduction, reducing the alternative minimum tax for individuals and eliminating it for corporations, doubling the estate tax exemption, and reducing the penalty for violating the individual mandate of the Affordable Care Act (ACA) to $0. The New York Times has described the TCJA as "the most sweeping tax overhaul in decades". Most of the changes introduced by the bill went into effect on January 1, 2018, and did not affect 2017 taxes. Many tax cut provisions contained in the TCJA, notably including individual income tax cuts, such as the changes to the standard deduction in §63 of the IRC, were scheduled to expire in 2025 while many of the business tax cuts were set to expire in 2028. However, in 2025, Congress passed the One Big Beautiful Bill Act, which extends most provisions of the TCJA beyond their original expiration dates. Extending the cuts have caused economists across the political spectrum to worry it would boost inflationary pressures and worsen America's fiscal trajectory. The Congressional Budget Office estimates that extending the expiring provisions would add $4.6 trillion in deficits over 10 years. Studies show the TCJA increased the federal debt, as well as after-tax incomes disproportionately for the most affluent. It led to an estimated 11% increase in corporate investment, but its effects on economic growth and median wages were smaller than expected and modest at best.

TCJA retained the preferential tax rates on long-term capital gains and qualified dividends and the 3.8 percent net investment income tax (NIIT). The NIIT applies to interest, dividends, short- and long-term capital gains, rents and royalties, and passive business income.
