A tariff is often framed in political debate as a tax a foreign country, or a foreign company, pays for the privilege of selling into a domestic market. Economic analysis of who actually bears the cost of a tariff — its "incidence," in economic terms — tells a more complicated story, and in many real-world cases, a substantial share of that cost lands on domestic buyers, not the foreign seller at all.
A tax on a transaction, paid by whoever has less room to walk away
Economists analyse tariff incidence the same way they analyse the incidence of any tax on a transaction: the actual burden falls, in proportion, on whichever side of the transaction — buyer or seller — has less flexibility to adjust in response to the price change. If a foreign exporter has other markets they can sell into just as easily, or other buyers who want their product, they can often simply raise their price to cover most of the tariff and keep selling roughly the same amount, passing most of the cost onto the buyer paying that higher price. If the exporter has fewer alternatives and needs to keep selling into the taxed market at nearly the same volume, they absorb more of the cost themselves by cutting their price to partially offset the tariff.
What the studies of recent tariffs actually found
Several economic studies examining tariffs imposed by the United States on a range of imported goods in recent years found that the price increases were passed through to American consumers and businesses buying those goods almost entirely, rather than being meaningfully absorbed by the foreign exporters the tariffs targeted — the opposite of the "foreigners pay it" framing tariffs are often sold to the public with.
What we're still unsure about
How much of a given tariff's cost lands on domestic buyers versus foreign sellers varies significantly by industry, by how substitutable the specific good is, and by how much market power the specific exporters involved actually hold — meaning tariff incidence isn't a fixed rule that applies identically to every product, and economists still have to study each specific case rather than apply one universal formula. Broader disagreement also persists over how to weigh the direct price costs to consumers against tariffs' other stated goals, like protecting domestic industries or jobs in the taxed sector, which is a separate policy question the incidence analysis alone doesn't resolve.
