Corporate tax cuts in the United States over the past decade have done three things at once: dropped the federal corporate income tax rate from 35 percent to 21 percent, cut what large companies actually pay by roughly half, and added trillions to the federal debt while producing little measurable wage gain for most workers. The 2017 Tax Cuts and Jobs Act made the rate cut permanent, and the One Big Beautiful Bill Act signed on July 4, 2025 extended and expanded the business write-offs that came with it. Here’s what the two laws changed, who benefited, and what it cost.
What the 2017 Law Changed
The Tax Cuts and Jobs Act permanently lowered the top statutory corporate income tax rate from 35 percent to 21 percent, effective for tax years beginning in 2018.1Tax Policy Center. How Did the Tax Cuts and Jobs Act Change Business Taxes The Joint Committee on Taxation estimated the rate cut alone would cost $1.3 trillion over ten years, the single most expensive provision in the law.2Center on Budget and Policy Priorities.

Only C-corporations pay the corporate income tax directly. Pass-through businesses — sole proprietorships, partnerships, and S-corporations — send profits to their owners’ individual returns, so to give them a parallel benefit the law created a 20 percent deduction on qualified business income under Section 199A.3Bipartisan Policy Center. The 2025 Tax Debate: The Corporate Tax Rate and Pass-Through Deduction
The rate move brought the U.S. from the fourth-highest statutory corporate rate in the world into the middle of the pack. In 2025 the combined federal-and-state rate sits at roughly 25.6 percent, slightly above the OECD average of 24.2 percent but below the G7 average of 28.6 percent.4Tax Foundation. Corporate Tax Rates by Country, 2025
What Companies Actually Pay Now
The statutory rate is a ceiling, not a bill. After deductions, credits, and depreciation, the average effective federal tax rate for 296 consistently profitable large corporations fell from 22 percent in 2013–2016 to 12.8 percent in 2018–2021, according to the Institute on Taxation and Economic Policy. Those companies paid $240 billion less over four years than they would have at pre-TCJA rates.5Institute on Taxation and Economic Policy. Corporate Taxes Before and After the Trump Tax Law
Individual company drops were larger. Verizon’s effective rate went from 21 percent to 8 percent, Walt Disney’s from 26 percent to 8 percent, and FedEx’s from 18 percent to 1 percent.5Institute on Taxation and Economic Policy. Corporate Taxes Before and After the Trump Tax Law In the law’s first year, 91 profitable Fortune 500 companies paid zero federal income tax, collectively receiving $73.9 billion in tax subsidies against the statutory rate.6Institute on Taxation and Economic Policy. Corporate Tax Avoidance in the First Year of the Trump Tax Law The pattern held. In 2025 at least 88 of the largest U.S. corporations, including Tesla, United Airlines, and PayPal, paid no federal income tax on a combined $105 billion in domestic pretax profits. The main drivers were accelerated depreciation, research credits, and international income deductions expanded by recent legislation.7Institute on Taxation and Economic Policy. 88 Profitable Corporations Paid Zero Income Tax in 2025
What Happened to Federal Revenue
Corporate tax collections dropped sharply after the cut. In the two decades before the TCJA, corporate tax revenue averaged about 1.7 percent of GDP. In 2018 and 2019 it fell to roughly 1.05 percent, a decline of nearly 40 percent from that modern average. In 2018 the United States ranked last among all 37 OECD nations in corporate tax revenue as a share of GDP.8U.S. Senate Finance Committee. Corporate Tax Receipts
Nominal receipts did recover on the back of rising corporate profits. Collections reached $372 billion in fiscal 2021, $420 billion in FY 2023, and $530 billion in FY 2024 before dropping to $452 billion in FY 2025.9Statista. Revenues From Corporate Income Tax and Forecast in the US The Congressional Budget Office initially estimated the TCJA would raise federal deficits by $1.5 trillion over its first decade, later revised to $1.9 trillion, and about $2.3 trillion including debt-service costs.10Tax Policy Center. How Did the TCJA Affect the Federal Budget Outlook
Where the Savings Went
The Trump administration’s Council of Economic Advisers argued in 2017 that cutting the corporate rate would raise average household income by at least $4,000 a year, working through higher investment, higher productivity, and then higher wages.11Economic Policy Institute. Cutting Corporate Taxes Will Not Boost American Wages The evidence points elsewhere.
An International Monetary Fund study of S&P 500 firms found only about 20 percent of the additional cash from the tax cut went to capital spending and research; much of the rest went to buybacks and dividends. Stock buybacks jumped 55 percent in 2018 compared with the previous year and, excluding the pandemic dip in 2020, have been higher every year since. Goldman Sachs projected buybacks would exceed $1 trillion in 2025 for the first time. Research from the Brookings Institution, the University of North Carolina, and the American Enterprise Institute found “no significant signs” of increased aggregate investment attributable to the 2017 law.12Center on Budget and Policy Priorities. Record Stock Buybacks Bolster Case for Raising Corporate Tax Rate Defenders of buybacks say they simply return capital to shareholders when companies have run out of productive uses, and that the money is reinvested elsewhere.13National Taxpayers Union Foundation. What Do Stock Buybacks Mean for the Economy
The wage picture is more concrete. A study using matched employer-employee tax records across roughly 15,500 firms found annual earnings did not change for workers in the bottom 90 percent of each firm’s income distribution. Gains concentrated among the top 10 percent, and especially executives, and were “not clearly linked to stronger firm performance.” The same study estimated the short-run split of the corporate tax cut at 51 percent to firm owners, 10 percent to executives, 38 percent to high-paid workers, and 0 percent to low-paid workers. Adjusted for equity holdings, roughly 80 percent of total gains accrued to the top 10 percent of earners.14Patrick Kennedy et al. Tax Cuts and Jobs Act Research Paper The CBO, the Treasury’s Office of Tax Analysis, and the Tax Policy Center have long attributed 75 to 80 percent of the economic incidence of corporate taxes to capital income rather than wages.11Economic Policy Institute. Cutting Corporate Taxes Will Not Boost American Wages
Growth That Was Promised vs. Delivered
GDP growth ticked up from 2.4 percent in 2017 to 2.9 percent in 2018, then slowed to 2.3 percent in 2019. Citing IMF research, the Tax Policy Center attributed the 2018 bump primarily to a short-term boost in demand rather than the long-run supply-side effects proponents predicted. A Congressional Research Service analysis noted that the categories of investment that increased in 2018 did not match the categories whose costs were most reduced by the law.15Tax Policy Center. How Might the Tax Cuts and Jobs Act Affect Economic Output
The CBO projected the TCJA would raise GDP by 0.6 percent by 2027. Because much of the associated investment was expected to be financed with foreign capital, with profits and interest flowing abroad, the projected benefit to Gross National Product was only 0.2 percent.15Tax Policy Center. How Might the Tax Cuts and Jobs Act Affect Economic Output Because the tax cut arrived with the economy near full capacity and unemployment low, whatever demand it added was partly offset by the Federal Reserve holding interest rates higher to contain inflation.
What the 2025 Law Added
The One Big Beautiful Bill Act, signed on July 4, 2025, left the 21 percent corporate rate alone. What it did was restore and expand the deductions and write-offs that had been expiring or phasing out, further reducing what companies owe.16Tax Policy Center. 2025 Tax Cuts Tracker
The law permanently restored 100 percent bonus depreciation for short-lived business assets (equipment, machinery, and similar property) purchased after January 19, 2025, letting companies deduct the full cost in the year of purchase instead of over multiple years.17Internal Revenue Service. One Big Beautiful Bill Provisions It reinstated immediate expensing for domestic research and development costs, reversing a 2022 change that required companies to amortize those expenses over five years. The more generous EBITDA-based limit on business interest deductions was made permanent.18Tax Foundation. One Big Beautiful Bill Tax US Manufacturing
A new, temporary provision allows 100 percent expensing of qualifying manufacturing and production structures (factories and production buildings, not offices or administrative space) placed in service before January 1, 2031. Construction has to begin after January 19, 2025 and before January 1, 2029, and if the property is repurposed for non-production use within ten years the deduction is recaptured as ordinary income.19Internal Revenue Service. IRS Notice 26-16: Qualified Production Property Because the incentive is temporary, analysts expect it to shift the timing of investment more than to raise the long-run growth rate.20Tax Foundation. OBBBA Expensing Manufacturing Structures
To offset the cost, the law repealed or accelerated the phase-out of several clean energy tax credits from the 2022 Inflation Reduction Act. Consumer credits for electric vehicles, residential energy improvements, and clean-energy home construction were repealed, and wind and solar projects were made ineligible for the newer clean electricity credits unless they enter service before the end of 2027. Those changes save an estimated $484.5 billion over ten years.21Tax Foundation. Big Beautiful Bill Green Energy Tax Credit Changes
Reviving the expiring TCJA business provisions will cost $772 billion over ten years, with an additional $285 billion in new business tax cuts, according to the Committee for a Responsible Federal Budget. The CBO estimates the law as a whole, including individual tax cuts and spending changes beyond the corporate provisions, will add $4.1 trillion to the debt through 2034, rising to as much as $5.5 trillion if temporary provisions are eventually made permanent.22Committee for a Responsible Federal Budget. Top 13 Fiscal Charts of 2025 The Tax Foundation projects C-corporations will see a $137.2 billion reduction in tax liability in 2026 alone, with manufacturing receiving the largest share at $60.3 billion.18Tax Foundation. One Big Beautiful Bill Tax US Manufacturing The CBO also scored the law as producing “negative dynamic feedback,” meaning the borrowing needed to finance the cuts pushes up interest rates enough to partly undercut their economic benefits.
Pass-Through Owners and International Rules
The Section 199A pass-through deduction was set to expire at the end of 2025. The Joint Committee on Taxation estimated that extending the 20 percent deduction through 2034 would cost about $730 billion. The House Ways and Means Committee’s 2025 proposal went further, raising the deduction to 23 percent and eliminating the income caps that had phased it out for high-earning service professionals.23Tax Law Center. Ways and Means Proposes Making Costly 199A Pass-Through Deduction More Generous
On the international side, the 2025 law renamed and reworked the TCJA’s cross-border regimes. GILTI became “net CFC tested income,” with a 40 percent deduction yielding an effective rate of 12.6 percent. FDII became “foreign-derived deduction eligible income,” with a 33.34 percent deduction and an effective rate of about 14 percent. Both dropped the asset-based calculations at the core of the original framework. The BEAT rate was locked permanently at 10.5 percent, preempting a scheduled 2026 increase to 12.5 percent.24RSM US. International Tax Reform Under the One Big Beautiful Bill Act
Running alongside all of this is the OECD’s Pillar Two framework, under which 147 countries have agreed to impose a 15 percent minimum effective tax on multinationals with annual revenue of at least €750 million. Australia, Canada, and most of the European Union have enacted implementing legislation.25PwC. Pillar Two Country Tracker The United States has not adopted conforming legislation, and the U.S. system is not fully compliant, partly because the renamed GILTI regime pools foreign income globally rather than country by country. The Tax Foundation estimates foreign adoption of the framework will, on net, raise U.S. corporate tax revenue by about $34.9 billion over a decade: foreign minimum taxes cut U.S. foreign tax credits by $64.3 billion, but profit-shifting back into the United States adds $99.3 billion.26Tax Foundation. Global Minimum Tax and US Tax Base
The Center for American Progress calculated that tax cuts enacted under the Bush and Trump administrations account for 57 percent of the increase in the debt-to-GDP ratio since 2001, and more than 90 percent when one-time costs from the Great Recession and the pandemic are excluded, adding an estimated $10 trillion to the national debt.27Center for American Progress. Tax Cuts Are Primarily Responsible for the Increasing Debt Ratio The CBO has estimated that each percentage point of increase in the corporate rate would generate roughly $100 billion in additional revenue.28NBC News.
