Costco received $184 million in tariff refunds from U.S. Customs and Border Protection during the fourth quarter. The recovery, which includes $174 million in principal and $10 million in interest, follows a Supreme Court ruling limiting presidential tariff authority.
Why it matters
The refund stems from a February 2026 Supreme Court decision regarding the International Emergency Economic Powers Act, which has prompted broader federal action as officials process billions in repayments. For operators, this highlights a significant compliance and potential cash-flow recovery opportunity linked to shifting federal trade authority.
Costco received $184 million in tariff refunds, contributing to a quarter where the company posted $96 billion in revenue, up 11% year-over-year. Net income for the period reached $3 billion, a 15% increase compared to the prior year.
The players
Costco
A global warehouse club retailer operating 950 locations with a membership-based business model.
U.S. Customs and Border Protection
The federal agency responsible for managing border security and the collection and refunding of import tariffs.
U.S. Supreme Court
The highest judicial body in the United States, which recently limited executive authority regarding international trade tariffs.
The details
The refunds were triggered by a February Supreme Court ruling that found the President lacked the authority to impose certain tariffs under the International Emergency Economic Powers Act. Costco has moved to reinvest these funds into everyday products and nonfood goods to maximize value for members across its 950 global warehouses. The company anticipates additional refunds beyond the initial $184 million as federal agencies continue to process claims.
Timeline
February 2026: The Supreme Court ruled against the president's tariff imposition authority.

Market Landscape
This development follows the Supreme Court ruling on the International Emergency Economic Powers Act, which has effectively reset the legal threshold for executive tariff authority. It places Costco among the entities benefiting from the widespread reversal of previous trade levies.
Operators should consult with legal and trade counsel to determine if their import history qualifies for similar tariff recovery under the recent Supreme Court precedent. Reviewing historical duty payments for potential refunds could provide a meaningful one-time cash-flow infusion.
The takeaway
The Supreme Court ruling has created a significant mechanism for recovering past tariff payments, shifting the financial calculus for importers. Operators should track their supply chain duty history to identify if they are eligible to file for similar refunds.
