President-elect Donald Trump won Tuesday’s presidential election partly by addressing Americans’ economic anxieties over higher prices.

Nearly half of all voters said they were worse off financially than they were four years ago, the highest level in any election since 2008, according to an NBC News exit poll.

But a cornerstone of Trump’s economic policy — sweeping new tariffs on imported goods — would likely exacerbate the very Biden-era inflation Trump lambasted on the campaign trail, according to economists.  

There’s still much uncertainty around how and when such tariffs might be implemented. If they were to take effect, they would likely raise prices for American consumers and disproportionately hurt lower earners, economists said.

The typical U.S. household would pay several thousand more dollars each year on clothing, furniture, appliances and other goods, estimates suggest.

“It’s bad for consumers,” said Mark Zandi, chief economist at Moody’s. “It’s a tax on consumers in the form of higher prices for imported goods.”

“It’s inflationary,” he added.

He and other economists predict the proposed tariffs would also lead to job loss and slower economic growth, on a net basis.

The Trump campaign didn’t immediately respond to a request for comment from CNBC on the impact of tariffs or their scope.

Tariffs have been around for centuries. However, their importance as a source of government revenue has declined, especially among wealthy nations, according to Monica Morlacco, an international trade expert and assistant professor of economics at the University of Southern California.

Now, the U.S. largely uses tariffs as a protectionist policy to shield certain industries from foreign competition, according to the Brookings Institution, a think tank.

Trump imposed some tariffs in his first term — on washing machines, solar panels, steel, aluminum and a range of Chinese goods, for example. The Biden administration kept many of those intact.

However, Trump’s proposals from the campaign trail are much broader, economists said.

He has floated a 10% or 20% universal tariff on all imports and a tariff of at least 60% on Chinese goods, for example. Last month, the president-elect suggested vehicles from Mexico have a tariff of 200% or more, and in September threatened to impose a similar amount on John Deere if the company were to shift some production from the U.S. to Mexico.

“To me, the most beautiful word in the dictionary is ‘tariff,'” Trump said at the Chicago Economic Club in October. “It’s my favorite word. It needs a public relations firm.”

A 20% worldwide tariff and a 60% levy on Chinese goods would raise costs by $3,000 in 2025 for the average U.S. household, according to an October analysis by the Tax Policy Center. Trump’s plan would reduce average after-tax incomes by almost 3%, according to the tax think tank.

Additionally, a 200% Mexico-vehicle tariff would increase household costs by an average $600, TPC said.

American consumers would lose $46 billion to $78 billion a year in spending power on apparel, toys, furniture, household appliances, footwear and travel goods, according to a National Retail Federation analysis published Monday.

“I feel pretty confident saying [tariffs] are a price-raising policy,” said Mike Pugliese, senior economist at Wells Fargo Economics. “The question is just the magnitude.”

The reason for these higher costs: Tariffs are paid by U.S. companies that import goods. The “vast majority” of that additional cost is passed on to American consumers, while only some of it is paid for by U.S. distributors and retailers or by foreign producers, said Zandi of Moody’s.

Philip Daniele, president and CEO of AutoZone, alluded to this dynamic in a recent earnings call.

“If we get tariffs, we will pass those tariff costs back to the consumer,” Daniele said in September.

The U.S. imported about $3.2 trillion of goods in 2022, for example, said Olivia Cross, a North America economist at Capital Economics. A back-of-the-envelope calculation suggests a 10% across-the-board tariff would be roughly equivalent to a $320 billion tax on consumers, Cross said.

Trump has proposed various tax breaks on the campaign trail. Additionally, tax cuts enacted by Trump in 2017 are due to expire next year, and tariff revenue may potentially be used to extend them, should Congress pass such legislation, economists said.

However, the typical U.S. household would still lose $2,600 a year from Trump’s tariff plan, even after accounting for an extension of the 2017 tax cuts, according to an analysis by the Peterson Institute for International Economics.

The U.S. economy would also likely suffer due to other tariff “cross currents,” Zandi said.

While U.S. companies that financially benefit from protectionist tariff policies may add jobs, the total economy would likely shed jobs on a net basis, Zandi said.

This is because countries on which the U.S. imposes tariffs would likely retaliate with their own tariffs on U.S. exports, hurting the bottom lines of domestic businesses that export goods, for example, Zandi said.

Higher prices for imported goods would likely also lead to lower consumer demand, weighing on business profits and perhaps leading to layoffs, he said.

In June, the Tax Foundation estimated Trump’s tariff plan would shrink U.S. employment by 684,000 full-time jobs and reduce its gross domestic product, a measure of economic output, by at least 0.8%.

Capital Economics expects the Trump administration would introduce tariffs — and a curb on immigration — in the second quarter of next year, the group said in a note Tuesday night. Together, those policies would cut Gross Domestic Product growth by about 1% from the second half of 2025 through the first half of 2026 and add 1 percentage point to inflation, it said.

Former President Donald Trump has defeated Vice President Kamala Harris to win the White House, which could broadly impact taxpayers — but the details remain unclear, according to policy experts.

Enacted by Trump in 2017, the Tax Cuts and Jobs Act, or TCJA, will be a key priority for the president-elect in 2025. The law brought sweeping changes, including lower tax brackets, higher standard deductions, a more generous child tax credit and bigger estate and gift tax exemption, among other provisions.

Those individual tax breaks will sunset after 2025 without action from Congress, which could trigger higher taxes for more than 60% of taxpayers, according to the Tax Foundation. However, Trump wants to fully extend expiring TCJA provisions.

Plus, most of Trump’s tax policy requires Congressional approval, which could be challenging, depending on control of the Senate and House of Representatives and support within the Republican party.

While Republicans secured a Senate majority, control of the House remains uncertain. If Democrats flip the House, we could see “more gridlock” in Congress, which could stall Trump’s agenda, Gleckman explained.

Tax negotiations could also be tough amid growing concerns about the federal budget deficit, according to Erica York, senior economist and research manager with the Tax Foundation’s Center for Federal Tax Policy. 

“The budget math is a lot harder this time around than it was back in 2017,” with higher interest rates and a bigger baseline budget deficit, she said. The deficit topped $1.8 trillion in fiscal 2024. 

Fully extending TCJA provisions could decrease federal revenue by $3.5 trillion to $4 trillion over the next decade, depending on the scoring model, according to the Tax Foundation.  

On the campaign trail, Republican presidential candidate Donald Trump made a notable promise to retirees: No taxes on Social Security benefits.

Now that Trump has won a second presidential term, that may prompt Social Security’s beneficiaries to wonder whether that change may come to pass.

But nixing those taxes may be a difficult task, even if Trump has a Republican majority in both the Senate and the House of Representatives. Any changes to Social Security would require at least 60 Senate votes, and Republicans would therefore need some Democratic support to pass those changes.

Just eliminating taxes on benefits, without any other changes to make up for that loss in revenues, would worsen the program’s current funding woes, experts say.

“It’s hard for me to imagine that Democrats would be willing to provide votes to get over that 60-vote threshold and weaken Social Security solvency,” said Charles Blahous, senior research strategist at the Mercatus Center at George Mason University, who has also served as a public trustee for Social Security and Medicare.

“I think a lot of Republicans would have heartburn about it, too,” he said.

Ending taxes on Social Security benefits — along with other Trump proposals to end taxes on tips and overtime, impose tariffs and deport immigrants — would “dramatically worsen” Social Security’s finances, the Committee for a Responsible Federal Budget found in a recent report.

The Trump campaign has pushed back on those findings, calling the Committee for a Responsible Federal Budget “consistently wrong” in a statement to CNBC when the report was released.

The campaign did not respond to a request for comment on Wednesday, about where the proposal stands on Trump’s priority list following his inauguration.

The Social Security trust fund used to help pay retirement benefits is projected to run out in 2033, according to the program’s actuaries. At that time, beneficiaries could see across-the-board benefit cuts, though the president may have the ability to determine how those reductions are distributed among beneficiaries, according to recent research.

Households with between $63,000 and $200,000 in income would benefit most from the change, according to an August analysis from the Urban-Brookings Tax Policy Center.

Lower income households making $32,000 or less would not get a tax cut, as most of their Social Security benefits are not currently taxed. Meanwhile, those with between $32,000 and $60,000 in annual income may see about $90 in tax cuts, according to the research.

“You’re giving a tax break to the higher-income senior population, so that might wind up mitigating its political sale ability as well,” Blahous said.

Currently, up to 85% of Social Security benefits may be taxed based on an individual’s or married couple’s income. Those taxes are determined based on a formula called combined income, or the sum of adjusted gross income, nontaxable interest and half of Social Security benefits.

Individuals face up to 85% in taxes on their benefits if they have more than $34,000 in combined income; for married couples that applies if their combined income is more than $44,000.

Individual beneficiaries may pay taxes on up to 50% of their benefits on combined income between $25,000 and $34,000, or for married couples with between $32,000 and $44,000.

Because those thresholds are not adjusted, more Social Security benefit income becomes subject to income taxes over time.

For now, financial advisors say it is too early to factor in the elimination of taxes on benefits into financial plans.

“You don’t know what the law or policy is going to be if it hasn’t even been properly drafted yet, much less adopted,” said David Haas, a certified financial planner and owner of Cereus Financial Advisors in Franklin Lakes, New Jersey.

“I wouldn’t jump to any conclusions,” he said.
