Policymakers make complex trade-offs when considering tariffs—while they can generate government revenue and encourage the consumption of locally produced goods, they can also lead to higher consumer prices and may negatively impact economic growth.

Tariffs are taxes levied on goods imported from abroad.

An economic evaluation of US tariffs

Most economists agree that the implementation of large-scale tariffs on foreign goods would hurt both the American and global economies. This video from The Wall Street Journal explains the rationale for tariffs as a tool for domestic job creation, but explains why they may hurt the overall economy.

Tariffs once fueled the US economy, historically serving as a primary source of revenue and a means to protect domestic industries.

The overall economic effect of President Trump's 2025 tariffs remains unclear

Researchers from UCLA and Yale found that tariff revenue and gains to US producers largely offset importers' costs—but the broader picture is murkier, as the trade deficit rose, manufacturing jobs declined, and 90% of tariff costs were passed through to importers rather than absorbed by foreign exporters.

Listen to a podcast episode that outlines 250 years of world trade history.

The history of tariffs stretches back to ancient Rome and Greece, where taxes were levied on imported grain and textiles to control trade.

How do tariffs work?

This brief animated video from Time walks through a simple example of a tariff on a single good, illustrating how this would affect the market for the good—both domestically and abroad—and who would eventually bear the cost of the tariff.

Revenue from tariffs goes to the US Treasury's general fund.

Tariffs are typically paid by the importing company or organization to the US Treasury.

Behind the scenes on tariff politics

Economist Gene Grossman joined the Trade Talks Podcast to discuss why tariffs really happen. The episode digs into how voters, politicians, lobbyists, and even campaign cash can affect when protectionist trade policies are put forward. Produced in 2019, the podcast also discusses how populist trade policies and identity politics accounted for Donald Trump’s victory in the 2016 Presidential election.

A trade war is an economic conflict where nations impose tariffs or other trade barriers on each other in retaliation for similar actions.

President Trump's 2025 Tariffs added less inflationary pressure to the economy than expected in their first year

A year after the so-called "Liberation Day" in April 2025, tariffs have had a milder effect on inflation than feared—core goods prices have added only about 0.2% to the headline Consumer Price Index—but persistent policy uncertainty has rattled small business owners, who say the constant back-and-forth makes long-term planning difficult.

Auto and consumer goods companies absorbed billions in costs due to President Trump's 2025 tariffs.

See comparisons of different countries' taxation strategies

Taxes are a major revenue source for most countries, and how each government taxes citizens often reflects the country's economy. Developed countries tax at much higher rates than developing ones, and as a country grows its GDP, it also typically grows the proportional percentage of taxes it gains from its citizens.

The Smoot-Hawley Tariff Act—which was passed during the Great Depression with the goal of reviving domestic industry—is among the most famous pieces of economic legislation in US history.

Tax policy can have a direct impact on the national debt, with past presidents' changes to tax codes inflating the deficit.

Trump's 2025 tariffs represent a significant break from the rules-based trade order

The Trump administration imposed broad tariffs on other countries outside WTO rules in 2025, claiming that those countries had long violated trade agreements and that the US was simply leveling the playing field.

The General Agreement on Tariffs and Trade and its successor, the WTO, was formed to reduce trade barriers between nations.

Some policymakers take issue with long-term capital gains being taxed at a preferential rate compared to income from paid work

The concept of taxing unrealized capital gains—when an asset’s value increases but has yet to be sold—has been increasingly debated. Other policymakers in recent years have supported lowering the highest long-term capital gains tax rate and are generally opposed to levying taxes on unrealized capital gains.

Trade between the US and China has significantly increased in recent decades.

What something costs is reflective of a balance in the market determined by the amount of demand relative to the supply of goods and services

Because economies are complex systems, a wide variety of issues influence this balance—including some things generally considered to be positive, like rising wages.

Global trade volume is roughly 45 times what it was when the General Agreement on Tariffs and Trade was founded

Since 1950, world trade values have grown nearly 410 times, mainly due to the successive tariff reductions negotiated under GATT and the WTO.

The GATT and its successor, the WTO, were established to lower trade barriers

Signed in 1947, the General Agreement on Tariffs and Trade began systematically reducing tariffs and trade barriers among member nations. In 1995, it was replaced by the World Trade Organization, which expanded those rules and established a formal dispute settlement system.

The Tariff Act of 1789 was one of America's first acts.

For everyday Americans, a relatively high national debt can lead to higher interest rates on financial products such as mortgages.

Fast fashion companies such as Temu and Shein often took advantage of the de minimis exemption, a US tariff loophole that ended in 2025.

Raising interest rates can help control inflation

While controlling a complex and dynamic economy is difficult, interest rates—more specifically, the rate at which banks lend each other money overnight—are a powerful tool. Generally, raising the rate makes purchases more expensive and cools an overheated economy.

National parks boost local economies, but they can also harm local land

Increased tourism and job creation are big wins for the small towns outside national parks, but the influx of visitors can also have negative effects, including wildlife destruction and overdevelopment.

Despite the Supreme Court ruling that President Donald Trump's 2025 tariffs were unconstitutional, billions of dollars in refunds remain unresolved

Over 2,000 lawsuits seeking refunds have been filed by major companies, including FedEx and Costco, but CBP says its systems can't handle the volume. Interest on unpaid refunds is accruing at an estimated $650M per month.

Trump's H-1B fee hike could reshape US industries and global talent flows

Analysts warn the new H-1B fee could trigger labor shortages in tech, medicine, and universities; push firms to offshore more work; and drive skilled Indian workers and students toward other countries—weakening America's innovation edge.

The 16th Amendment paved the way for capital gains taxes

Ratified in 1913, the 16th Amendment paved the way for a far-reaching federal income tax and supercharged the country’s coffers. Before then, the US depended on import tariffs and so-called consumption taxes to raise revenue.

Gross domestic product only accounts for consumer spending, investments, government spending, and net exports—meaning factors such as stock market performance, Social Security payments, household labor, and the value of environmental damage largely aren't represented.

Interest rates have historically been an indicator of the US economy's overall health.

Read why the information Americans have about our tax system might be misleading

For many, filing taxes can be complicated and overwhelming. Some argue that the tax system obscures certain aspects of the US tax code, making it difficult for taxpayers to accurately assess potential reforms.

Before the 16th Amendment, US tax law required direct taxes to be directly apportioned to a state's population

Due to these requirements, the federal government could not impose many direct taxes. Direct taxes include property and income taxes, whereas indirect taxes include duties and excises.

The US apparel and textile industry was long set up to limit competition from nations in the developing world—but shifts in international trade regulation in the 1990s changed that, paving the way for the fast fashion industry to develop.

Study shows H-1B visas depress wages and reduce consumer tech costs

A paper from the National Bureau of Economic Research found that without H-1B workers, American computer scientists would earn 2.6% to 5.1% more and domestic employment could rise by 11%, but consumers would pay more for advanced technology, and output would decrease.

The Supreme Court ruled in February 2026 that Trump's emergency tariff powers didn't extend to imposing tariffs

In a 6-3 decision, the court held that the International Emergency Economic Powers Act—a 1977 law granting the president authority to regulate commerce during national emergencies—does not authorise the president to unilaterally impose tariffs, a power the Constitution reserves to Congress.

While critics of labor unions argue that unions make it difficult to discipline low performers and drive up labor costs, union advocates believe that unions are a useful tool for increasing workers' pay and benefits.

Prices can still feel high even if inflation is slowing

This is partly because a recent spike in inflation raised prices permanently, so even though the pace of price growth has slowed, prices have still gone up for good.

Treasury bonds, notes, and bills are critical vehicles for the federal government to raise money for public expenses and manage the national debt.

If the estate tax is repealed, more expensive alternatives might come in its place

The federal estate tax has been up for political debate for decades. Many want to get rid of it altogether. If repealed other tax options, like capital gains taxes, could have people paying more in taxes than before.

Since 1913, Americans have paid income taxes at varying rates

In the 2020s, the top marginal tax rate has floated around 37%, relatively lower than previous eras. Some have called for boosting the rate significantly to tax the highest earners.

Critics argue that the World Bank, IMF, and WTO were designed to serve Western interests

Some analysts from developing nations argue that the Bretton Woods institutions were designed to reinforce Western economic dominance rather than to promote fair development for poorer countries. Supporters respond that these institutions have improved living standards worldwide.

Understanding the low corporate tax rate in the US

Corporate taxes, which make up roughly a third of the federal government's revenue, have been calculated using a flat 21% rate since the Tax Cuts & Jobs Act of 2017. The current rate is considered low both by historic standards (it averaged over 50% in the 1950s and 1960s) and compared to other countries.

Market concentration and high markups don't always signal a monopoly

When regulators and economists evaluate whether a company constitutes an illegal monopoly, they often consider its overall market share or its relatively high price markups. This piece argues that the Olley-Pakes decomposition is a better measure, identifying whether customers within a market are switching to more productive companies.

ETFs and mutual funds are both taxed on capital gains and on dividends.
