Costco Sues U.S. Government to Recover Tariff Payments Imposed Under Trump Administration

Dec 2, 2025

Costco has filed a lawsuit against the U.S. government, seeking to recover tariffs it paid on imported goods under orders made by former President Donald Trump. The case focuses on tariffs enacted under the International Emergency Economic Powers Act (IEEPA).

Costco argues that if the Supreme Court later rules these tariffs were imposed without proper legal authority, the company should be able to get its money back. Costco’s lawsuit aims to secure a refund of those payments and to stop further collection of the tariffs while the Supreme Court makes its decision.

There is a looming December 15 deadline that might prevent Costco from recovering the duties it already paid, which is why the company has taken this legal action now. Multiple lower courts have already found that the tariffs may have been imposed illegally, but Costco wants to ensure its rights are protected before the Supreme Court issues its final ruling.

Why is Costco suing the U.S. government?

Costco is suing to get a refund of tariffs it paid on imported goods if the Supreme Court finds those tariffs were not legally imposed.

What are these tariffs related to?

The tariffs were put in place by the Trump administration under the International Emergency Economic Powers Act (IEEPA).

What could happen if Costco does not sue now?

If Costco waits, a deadline on December 15 could make it impossible for the company to recover the money it paid in tariffs, even if the tariffs are later found to be illegal.

Does the Supreme Court decision affect only Costco?

No, other companies could also be affected, but this lawsuit is specifically about Costco recovering its own tariff payments.
