Tax Cuts and Jobs Act (United States) was landmark federal legislation that reformed the United States Internal Revenue Code in 2017. Enacted by the 115th United States Congress and signed by Donald Trump, the law altered individual income tax brackets, corporate tax rates, deductions, and international taxation rules. It generated extensive analysis from institutions such as the Congressional Budget Office, Joint Committee on Taxation, Federal Reserve, and International Monetary Fund.

Background and legislative history

Legislative origins trace to policy agendas advanced by Republican Party, House Speaker Paul Ryan, Senate Majority Leader Mitch McConnell, and the Trump administration, with proposals echoing prior plans by Romney–Ryan 2012 allies and advisors from Heritage Foundation. Major procedural steps included passage of a House bill modeled on Tax Cuts and Jobs Act of 2017 (House) and a Senate reconciliation bill shepherded through committees chaired by Kevin Brady and Orrin Hatch. Floor maneuvers in the United States Senate used the budget reconciliation process under the Budget Act of 1974 to bypass a filibuster, culminating in final votes after negotiations between Paul Ryan, Mitch McConnell, John McCain, and Lamar Alexander. The bill was signed by Donald Trump on December 22, 2017, following staff work by the United States Department of the Treasury and advisers from Erskine Bowles-style corporate tax reform advocates.

Key provisions

Major corporate reforms included a permanent reduction of the statutory corporate rate to 21%, adoption of a modified territorial system with a participation exemption, and introduction of provisions such as the Business Interest Limitation and new rules for Global Intangible Low-Taxed Income (GILTI). Individual provisions created new income tax brackets, nearly doubled the standard deduction while capping the state and local tax (SALT) deduction, limited personal exemptions, and expanded the Child Tax Credit. The act altered pass-through taxation via a 20% deduction for qualifying business income, modified Alternative Minimum Tax rules, and changed estate tax exemptions. It repealed the individual mandate penalty from the Patient Protection and Affordable Care Act through an amendment of the Internal Revenue Code effective 2019.

Economic effects and analyses

Analyses by the Congressional Budget Office, Joint Committee on Taxation, International Monetary Fund, Organisation for Economic Co-operation and Development, and Federal Reserve Board estimated impacts on gross domestic product growth, investment, and budget deficits. The CBO projected increased federal budget deficits and higher national debt over a decade, while some International Monetary Fund and Federal Reserve analyses anticipated modest short-term GDP boosts and capital repatriation effects. Private-sector studies from Tax Foundation, Urban–Brookings Tax Policy Center, Institute on Taxation and Economic Policy, and various investment banks debated long-term productivity gains versus crowding effects on public spending. Macroeconomic discussions referenced models used by Dynamic scoring proponents and critics such as Paul Krugman and Greg Mankiw.

Distributional impact and tax incidence

Distributional studies from the Tax Policy Center, Congressional Budget Office, and Joint Committee on Taxation assessed after-tax income changes across income quintiles and deciles. Analyses commonly found larger percentage and dollar benefits to higher-income households and corporations, with temporary gains for many middle-income taxpayers due to bracket changes and the expanded standard deduction. The erosion of certain deductions, combined with the SALT cap, shifted burdens in high-tax states like California, New York (state), and New Jersey. Debates over tax incidence involved perspectives from scholars affiliated with Harvard University, Brookings Institution, American Enterprise Institute, and Center on Budget and Policy Priorities.

Political debate and public response

Public discourse involved partisan frames from Republican Party proponents emphasizing economic growth, job creation, and corporate competitiveness, while Democratic Party critics argued about distributional fairness and deficit impacts. Media coverage in outlets such as The New York Times, The Wall Street Journal, The Washington Post, and Fox News highlighted lobbying by corporations, responses from state governors like Andrew Cuomo and Gavin Newsom, and civic reactions from taxpayer advocacy groups and labor unions including AFL–CIO. Opinion polling by Pew Research Center and Gallup tracked public approval across time, with debates resurfacing during the 2018 United States elections and 2020 United States presidential election.

Implementation, compliance, and IRS guidance

Implementation required regulatory action by the Internal Revenue Service and rulemaking by the United States Department of the Treasury, producing numerous notices, proposed regulations, and temporary rules addressing GILTI, Base Erosion and Anti-Abuse Tax (BEAT), and the Qualified Business Income deduction. Compliance burdens affected accounting firms like the Big Four (accounting firms), corporate tax departments, and individual return preparers including H&R Block and Intuit. Litigation over interpretation arose in federal courts and was anticipated before the United States Tax Court and United States District Court venues.

Subsequent amendments and expirations

Several individual provisions are sunsetted or scheduled to expire in 2025 under the act's terms, prompting legislative discussions in the 116th United States Congress and 117th United States Congress about extensions, permanency for corporate provisions, and targeted reforms. Subsequent tax legislation and administrative guidance adjusted implementation details; proposals in the 2020 Democratic Party presidential primaries and the 117th United States Congress considered reversals or augmentations tied to infrastructure legislation and American Rescue Plan Act of 2021 fiscal trade-offs. Continued oversight by the Joint Committee on Taxation and Congressional Budget Office informs debates over long-term statutory changes and potential sunset modifications.
