The Trump Tax Cuts: Sold as Middle-Class Relief, Delivered for the Wealthy
The 2017 Tax Cuts and Jobs Act delivered an average tax cut of $51,000 to the top 1% while giving the bottom quintile roughly $40 — and now Trump's 2025 reconciliation bill makes those cuts permanent at a projected cost of $4.2 trillion, with the same skewed distribution baked in.
“Trump and Republican leaders sold the Tax Cuts and Jobs Act of 2017 as a middle-class tax cut, promising it would 'rocket fuel' economic growth, raise average household income by $4,000–$9,000 per year through wage increases, and that corporations would use their tax savings to hire workers and invest in America. Trump said the bill would 'cost me a fortune.' Treasury Secretary Steven Mnuchin pledged the tax cuts would 'pay for themselves' through growth. Now, with the 2025 'One Big Beautiful Bill' extending these provisions, the administration again frames permanence as essential relief for working Americans.”
According to the Tax Policy Center, Congressional Budget Office, and Institute on Taxation and Economic Policy, the TCJA delivered the vast majority of its benefits to the wealthy. The top 1% received an average cut of $51,000 while households in the bottom quintile got roughly $40. The top 20% captured approximately 65% of total benefits while the bottom 60% shared just 13%. Corporations used their windfall primarily for stock buybacks — S&P 500 companies spent $806 billion buying back their own shares in 2018 alone, versus just $1.5 billion in worker bonuses. The law added $1.9 trillion to the national debt over its first decade, and extending it costs an additional $4.2 trillion through 2035.
The Tax Cuts and Jobs Act (TCJA), signed into law by President Trump on December 22, 2017, was the largest overhaul of the U.S. tax code in three decades. It cut the corporate tax rate permanently from 35% to 21%, temporarily lowered individual income tax rates across most brackets, nearly doubled the standard deduction, and created a new 20% deduction for 'pass-through' business income under Section 199A. Republicans sold it to the public as a middle-class tax cut — but the distributional data tells a different story. The Tax Policy Center found that in 2018, the average household in the bottom income quintile (earning under roughly $25,000) received a tax cut of just $40. Middle-income households received about $800. Meanwhile, taxpayers in the top 1% of the income distribution — those earning $733,000 or more — received an average cut of approximately $33,000 on individual taxes alone, rising to $51,000 when corporate tax benefits are included. Across all income groups combined, the top 1% received 20.5% of total TCJA benefits in 2018.
The corporate tax cut — the most expensive and permanent provision of the TCJA — was justified by proponents with a specific economic theory: that cutting the corporate rate from 35% to 21% would be passed on to workers as higher wages. The White House Council of Economic Advisers predicted wage increases of $4,000 to $9,000 per household. This did not happen. Research by the Joint Committee on Taxation and Federal Reserve economists found that 'earnings do not change for workers in the bottom 90%' of the income distribution. Instead, corporations used their tax savings primarily to enrich shareholders: S&P 500 companies spent $806 billion on stock buybacks in 2018, up from $519 billion in 2017 — a 55% single-year increase. In the first two months after the TCJA passed, S&P 500 companies dedicated 106 times more money to share buybacks ($160 billion) than to worker bonuses and wage increases ($1.5 billion). An IMF study found that only about 20% of incremental corporate cash from the tax cuts went to capital investment or R&D; the rest went to buybacks and dividends.
The pass-through deduction (Section 199A) was marketed as relief for small business owners, but its benefits flow overwhelmingly to the wealthy. Section 199A allows owners of 'pass-through' businesses — such as partnerships, S-corporations, and sole proprietorships — to deduct 20% of their qualified business income. Analysis by the Center on Budget and Policy Priorities, based on Joint Committee on Taxation estimates, found that 61% of the Section 199A deduction's benefits flow to the top 1% of households. Only 4% goes to the bottom two-thirds of taxpayers. Economists who studied the provision found 'little evidence of changes in real economic activity as measured by physical investment, wages to non-owners, or employment,' according to a study by Lucas Goodman and colleagues. Over two-thirds of all 199A deductions claimed were by taxpayers with more than $200,000 in adjusted gross income, and over one-third by taxpayers with more than $1 million in AGI.
The TCJA's total cost to the federal budget was staggering. The Congressional Budget Office estimated in 2018 that the law would increase the federal deficit by approximately $1.9 trillion over its first decade — $433 billion more than the pre-enactment Joint Committee on Taxation estimate — when debt service costs are included. Debt held by the public was projected to rise from 91.2% of GDP to 97.3% as a result of the legislation. The promised 'self-financing' through economic growth never materialized: the Congressional Research Service concluded that growth patterns after the TCJA were 'not consistent with expected supply-side incentive effects.' Meanwhile, the law's individual income tax provisions were written to expire after 2025 — a deliberate budget maneuver to make the 10-year cost appear smaller — while the corporate rate cut was made permanent.
The expiration cliff has now been used as a political lever. Most TCJA individual provisions were set to sunset at the end of 2025, which would have raised taxes on virtually all households. Republicans used this deadline to push through the 'One Big Beautiful Bill Act,' signed by President Trump on July 4, 2025, which makes the expiring provisions permanent and adds new ones. The U.S. Treasury estimated that fully extending the expiring TCJA individual and estate tax provisions would cost $4.2 trillion between 2026 and 2035. The Committee for a Responsible Federal Budget notes that extending all TCJA provisions could cost up to $2.7 trillion through 2032 alone. The distributional skew remains: ITEP analysis found that the bottom 60% of taxpayers receive just 13% of TCJA benefits, while the top 5% receives 53%. By 2027, when only the permanent corporate provisions remain under the original law, 82.8% of remaining benefits would have flowed to the top 1% — a figure that underscores who the law was fundamentally designed to help.
The Tax Policy Center found the top 1% received an average TCJA tax cut of $51,000 in 2018 (including corporate benefits), while the bottom quintile averaged just $40 — a ratio of more than 1,250 to 1.
ITEP analysis found the bottom 60% of taxpayers received only 13% of total TCJA benefits, while the top 5% alone captured 53% of total benefits.
S&P 500 companies spent $806 billion on stock buybacks in 2018 — up 55% from $519 billion in 2017 — versus just $1.5 billion in worker bonuses in the two months after passage: 106 times more to shareholders than workers.
61% of the Section 199A pass-through deduction — marketed as a 'small business' tax break — flows to the top 1% of households, per CBPP analysis of JCT estimates; the bottom two-thirds of taxpayers receive just 4%.
The CBO estimated the TCJA would increase the federal deficit by $1.9 trillion over its first decade, with debt held by the public rising from 91.2% to 97.3% of GDP — while the promised economic growth to 'pay for' the cuts never materialized.
Trump's 2025 'One Big Beautiful Bill' makes expiring TCJA provisions permanent at a projected cost of $4.2 trillion through 2035, according to U.S. Treasury — extending the same top-heavy distribution indefinitely.
