The 2017 Trump tax cuts (TCJA) and subsequent 2025 extensions significantly increased the federal deficit. Estimates indicate they will add roughly $3.4 trillion to $4.1 trillion to the national debt over the 2025–2034 period, driven by a $4.5 trillion to $5.0 trillion reduction in revenue, partially offset by spending changes.
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 debt increase will be larger if some of TCJA's temporary tax cuts are extended.
The Tax Cuts and Jobs Act (TCJA) increased the standard deduction from $6,500 to $12,000 for individual filers, from $13,000 to $24,000 for joint returns, and from $9,550 to $18,000 for heads of household between 2017 and 2018. As before, the amounts are indexed annually for inflation.
The New York Times stated in an editorial that the full Bush-era tax cuts were the single biggest contributor to the deficit over the past decade, reducing revenues by about $1.8 trillion between 2002 and 2009.
1837: Andrew Jackson
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.
The terms “national deficit”, “federal deficit” and “U.S. deficit” have the same meaning and are used interchangeably by the U.S. Treasury. A surplus occurs when the government collects more money than it spends. The last surplus for the federal government was in 2001.
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.
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.
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.
Seven major tax cuts took effect for 2025 under the OBBBA:
The One Big Beautiful Bill Act (OBBBA) or the Big Beautiful Bill (P.L. 119-21), is a U.S. federal statute passed by the 119th United States Congress containing tax and spending policies that form the core of President Donald Trump's second-term agenda. The bill was signed into law by Trump on July 4, 2025.
TCJA made many large changes across multiple areas of the tax code, including most infamously reducing the corporate tax rate, increasing the standard deduction, and increasing the applicable exclusion amounts for estate taxes.
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.
There are three primary drivers of the overall growth in spending: America's aging population, rising healthcare costs, and rapidly escalating interest costs. Significant growth in those categories is combined with a tax system that is not designed to collect enough revenues to fund the promises that have been made.
Many economists and policymakers agree that such a target, and such prudence, is warranted. The target most commonly referenced is a 60% debt-to-GDP ratio.
Trump Tax Plan Changes: Standard Deduction
The 2017 Trump tax law (TCJA) nearly doubled the standard deduction for all filers, and OBBB bumped them up. If you're a single filer or if you're married filing separately, your standard deduction for 2025 rose to $15,750 under OBBBA.
FACT: The bill cuts taxes and lowers rates for all Americans. While the status quo tilts in favor of the wealthy, the Tax Cuts and Jobs Act delivers tax relief for middle-income Americans by doubling the standard deduction and lowering rates for those who need it most.
The rulings were stayed pending appeal, allowing the tariffs to remain in effect. The Supreme Court consolidated V.O.S. Selections and Learning Resources into a single case and set arguments for the first week of November 2025. A decision is expected in January 2026.
The last time that the budget was balanced or had a surplus was the 2001 United States federal budget, under 42nd President Bill Clinton.
As the world's biggest gambling hub, Macao SAR has zero debt, bolstered by billions in gaming revenue and healthy financial reserves. Liechtenstein ranks in second, with virtually no debt and the only country in Europe ranking in the top 10.
The U.S. Treasury has reported a budget surplus of $27 billion for the month of June—the first time since 2017. This is excellent news for our economy and a signal that President Trump's pro-growth policies are on the right track!
