Summary

The Tax Cuts and Jobs Act (TCJA), enacted in 2017 and often referred to as the "Trump Tax Cuts," represents a significant overhaul of the United States federal tax code. This legislation, which largely took effect on January 1, 2018, implemented sweeping changes including reduced corporate and individual tax rates, an increased standard deduction, and enhanced family tax credits. It also eliminated personal exemptions, limited deductions for state and local taxes and mortgage interest, reduced the individual alternative minimum tax, eliminated the corporate alternative minimum tax, doubled the estate tax exemption, and set the Affordable Care Act's individual mandate penalty to zero. While the TCJA aimed to stimulate economic growth, studies indicate it increased the federal debt and disproportionately benefited the most affluent, with more modest impacts on economic growth and median wages than anticipated. Originally, many individual tax cuts were set to expire in 2025, and business tax cuts in 2028. However, in 2025, Congress passed the "One Big Beautiful Bill Act," extending most TCJA provisions beyond their initial expiration dates. This extension has raised concerns among economists about potential inflationary pressures and the worsening fiscal trajectory of the United States, with the Congressional Budget Office estimating it could add $4.6 trillion to deficits over ten years. The TCJA has also been referenced in discussions regarding tax policy and its impact on industries like Silicon Valley, as well as in broader conversations about immigration policy.

Tax Cuts and Jobs Act

The Tax Cuts and Jobs Act, Pub. L. 115–97 (text) (PDF), is a United States federal law that amended the Internal Revenue Code of 1986, and also known as the Trump Tax Cuts, but officially the law has no short title, with that being removed during the Senate amendment process. The New York Times described the TCJA as "the most sweeping tax overhaul in decades". 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. 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. 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 could boost inflationary pressures and worsen America's fiscal trajectory. The Congressional Budget Office estimated that extending the expiring provisions would add $4.6 trillion in deficits over 10 years.

    The Tax Cuts and Jobs Act (TCJA) was a major overhaul of the tax code, signed into law by President Donald Trump in his first term on Jan. 1, 2018. The Senate passed TCJA on Dec. 2, 2017, by a party-line vote of 51 to 49. The House passed its version by a vote of 224 to 201. No House Democrats supported the bill, and 12 Republicans voted against it. [...] The Tax Cuts and Jobs Act (TCJA) was the most significant tax code overhaul in three decades and created a single flat corporate tax rate of 21%. Many tax benefits that helped individuals and families were initially set to expire in 2025. The One Big Beautiful Bill Act (OBBBA, 2025) permanently establishes many individual provisions, such as the lower tax brackets, bigger standard deduction, and Qualified Business Income (QBI) deduction. [...] The TCJA cut the corporate tax rate to benefit shareholders, who tend to be higher earners. It only originally cut individuals' taxes for a limited period, though the OBBA extended or made permanent many of the cuts. It scaled back the AMT and estate tax and reduced the taxes levied on pass-through income. It did not close the carried interest loophole, which benefited professional investors.

  • Corporate Behavior and the Tax Cuts and Jobs Act

    The Tax Cuts and Jobs Act of 2017 (the “TCJA”) fundamentally altered United States tax law. Among other things, it broadly decreased income tax rates paid by individuals and corporations, eliminated miscellaneous itemized deductions, limited the state and local tax deduction, increased the standard deduction, reduced the alternative minimum tax for individuals and eliminated it entirely for corporations, and allowed a deduction for certain pass-through business income. [...] The TCJA made many important changes to U.S. corporate income tax law. Most fundamentally, the TCJA reduced the statutory rate on all corporate income to a flat 21 percent from a previous top marginal rate of 35 percent. Beyond reducing the statutory rate, the TCJA also affected several other provisions relevant for corporations, including those concerning earnings stripping(1)%20&p=1&sort=relevance&type=case&resultsNav=false), expensing and depreciating, net operating losses, and the taxation [...] The TCJA cut taxes by $1.5 trillion and in the process conferred significant tax benefits on U.S. corporations. Unlike the predictions of the TCJA’s proponents, economic growth has shown no sign of increasing nearly to the extent necessary for the tax cut to pay for itself. In addition to increases in discretionary spending passed shortly after the TCJA, the United States now faces the largest federal budget deficit it has ever experienced during a period of peace and economic growth.

  • One Big Beautiful Bill Act: Key Changes in the TCJA Extension

    Passed in 2017, the Tax Cuts and Jobs Act (TCJA) made several significant changes to the tax code that affected the tax planning strategies for millions of Americans. But many of these changes weren’t permanent and the legislation was set to expire at the end of 2025. In July 2025, Congress passed, and President Donald Trump signed into law, a comprehensive package focused on tax laws and many other issues known as the “One Big Beautiful Bill Act.” [...] The One Big Beautiful Bill Act includes numerous tax cuts and changes. Many make permanent or modify tax provisions from the 2017 Tax Cuts and Jobs Act (TCJA). [...] The 2017 Tax Cuts and Jobs Act lowered individual tax brackets across the board. Under the new legislation in 2025, these tax brackets have been made permanent (subject to changes enacted by a future Congress) and will remain as 10%, 12%, 22%, 24%, 32%, 35%, and 37%. “Knowing the new law makes permanent these brackets and other parts of the TJCA will better facilitate long-term tax planning,” says Willing. ### Increased standard deduction.
