The original Trump tax cuts (Tax Cuts and Jobs Act of 2017) are estimated to add roughly $1.9 trillion to the federal deficit over a decade, while extending the expiring provisions would cost significantly more, with estimates for extension ranging from $4 to over $4.5 trillion over 10 years, primarily due to cuts for individuals and businesses, adding to national debt and impacting future fiscal outlooks.
How did the TCJA affect the federal budget outlook? The Tax Cuts and Jobs Act cut taxes substantially from 2018 through 2025. The resulting deficits are adding $1 to $2 trillion to the federal debt, according to official estimates from before and shortly after enactment.
The Tax Cuts and Jobs Act ("TCJA") changed deductions, depreciation, expensing, tax credits and other tax items that affect businesses. This side-by-side comparison can help businesses understand the changes and plan accordingly.
Before the Trump tax cuts (Tax Cuts and Jobs Act of 2017 - TCJA), individual income tax rates ranged from 10%, 15%, 25%, 28%, 33%, 35%, up to a top rate of 39.6%, with different income brackets for single and married filers, while the top corporate tax rate was 35%, significantly higher than the post-TCJA 21% rate. The TCJA maintained seven brackets but adjusted rates and income thresholds, alongside major changes to deductions, credits, and the corporate tax structure, notes this Tax Foundation article.
The TCJA eliminated or restricted many itemized deductions for 2018 through 2025. This, together with a higher standard deduction, reduced the number of taxpayers who itemize deductions. In 2017, 31 percent of all individual income tax returns had itemized deductions, compared with just 8 percent in 2022.
At the end of 2025, the individual portions of the Tax Cuts and Jobs Act expire all at once. Without congressional action, 62 percent of filers could soon face a tax increase relative to current policy in 2026. At the same time, the price tag for extending the 2017 Trump tax cuts is in the trillions.
By reducing the incentive for households to claim itemized deductions for mortgage interest and property taxes, this law represents an unprecedented reduction in the tax-favored status of owner-occupied housing.
The Tax Cuts and Jobs Act of 2017 was legislation passed by the 115th Congress and signed into law by President Donald Trump.
The law cut the statutory corporate tax rate from 35 to 21 percent and made changes to many corporate tax breaks, expanding some while constraining others.
Nearly half (47%) of the tax cuts go to the top 1% of households, which get a tax break of nearly $215,000 a year. The bottom 20% get a tax cut of just $110. 2 Trump's plan will increase the deficit by $7.1 trillion,3 unless massive cuts are made to benefits and services that working Americans depend on.
The most detailed research yet on corporate response to the 2017 Republican tax law shows modest gains for workers and high cost to the federal debt.
Does the Trump Tax Plan Affect Capital Gains Tax Rates? Trump's tax law leaves existing capital gains tax rates and income tax brackets unchanged. Capital gains remain a key consideration for investors, especially those with taxable brokerage accounts, real estate holdings or long-term investment portfolios.
The Tax Cuts and Jobs Act (TCJA) of 2017 included several provisions that reduced the impact of the AMT. This involved higher AMT exemptions and an increased phase-out threshold for those exemptions. It also modified itemized deductions that were previously considered preference items.

This resulted in a huge government surplus of funds. (In 1835, the $17.9 million budget surplus was greater than the total government expenses for that year.) By January of 1835, for the first and only time, all of the government's interest-bearing debt was paid off.
Multiple other analyses have found that higher debt and deficits lead to upward pressure on interest rates. Paying for the cost of extending and expanding tax cuts will directly lead to lower interest rates than extension without offsets. Lower interest rates mean lower borrowing costs throughout the economy.
In terms of deficit reduction, the final monthly Treasury statement for FY 2025 (ending in September) showed a deficit of roughly $1.78 trillion, as compared to roughly $1.82 trillion for FY 2024. This means that the deficit did come down during Trump's second term, but quite modestly.
The Congressional Budget Office (CBO) estimated in 2018 that the 2017 law would cost $1.9 trillion over ten years, and recent estimates show that making the law's temporary individual income and estate tax cuts permanent would cost roughly another $4.2 trillion through 2035.
If the individual tax cuts expire, taxpayers in all income groups would face higher and more complicated taxes. Machinery and equipment expensing is a key provision that, if allowed to expire, would especially harm capital-intensive industries like manufacturing.
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 2012, during the fiscal cliff, Obama overcame the sunset provisions and made the tax cuts permanent for single people earning less than $400,000 per year and couples making less than $450,000 per year, but did not stop the sunset provisions from applying to higher incomes, under the American Taxpayer Relief Act of ...
No Tax on Overtime is a provision that was included in a larger tax reform bill that passed in July 2025. It allows certain workers to deduct up to $12,500 in qualified overtime compensation from their taxable income on their federal income tax return. Joint filers can deduct up to $25,000.
Under the law, there were numerous changes to the individual income tax, including changing the income level of individual tax brackets, lowering tax rates, and increasing the standard deductions and family tax credits while itemized deductions are reduced and the personal exemptions are eliminated.
Meanwhile, the tax rate reduction reduced the tax payments of middle class and poor taxpayers. The net effect was a marked shift in the tax burden toward the top 1 percent amounting to about 10 percentage points. Lower top marginal tax rates had encouraged these taxpayers to generate more taxable income.
The taxation of alimony on federal tax returns changed because of the Tax Cuts and Jobs Act of 2017 (TCJA). Today, alimony or separate maintenance payments relating to any divorce or separation agreements dated January 1, 2019, or later are not tax-deductible by the person paying the alimony.
