The year 2026 has been characterized by a judicial battle that has never been witnessed before by U.S importers and international businesses. The focal point in this tornado is the International Emergency Economic Powers Act (IEEPA). This law has been employed to make global generalized and reciprocal tariffs through the generalized and reciprocal tariffs.

The U.S. Supreme Court is bound to give a verdict that will either be in favor of the administration, which will require the billions of dollars collected in duties to be refunded, or it will be against the administration. This case is not only a trade update but an enormous change in the liquidity planning and corporate tax liability.

Does the IEEPA grant the President the power to "Tax"?

The fundamental beat of the Supreme Court reasoning is based on Article I, Section 8 of the Constitution, which even gives the authority to impose taxes and tariffs solely to Congress. The administration has countered that the power of the IEEPA to regulate importation in such circumstances as a national emergency carries the connotation of imposing tariffs. Experienced IRS tax experts (a former IRS tax agent, a former auditor, and experienced LA tax attorneys) who can help to manage the liabilities.

Nevertheless, its opponents claim that there is a fundamental difference between regulating (e.g. quotas or bans) on the one hand and revenues through taxation on the other. In case the Court finds that IEEPA does not permit the imposition of tariffs, all the dollars collected based on this authority since 2025 may be considered an illegitimate tax.

Can your business claim a refund for tariffs already paid?

When the Supreme Court invalidates the IEEPA tariffs, a huge window of reimbursement will be established. U.S. Customs and Border Protection (CBP) has gathered more than 140 billion in the mentioned duties up to the early part of 2026. In a highly rare pronouncement, the Court of International Trade (CIT) has just decided that the government is judicially estopped to reject the refunds owed to similarly situated plaintiffs in the event the government loses in the Supreme Court.

This is to say that, although you were neither a direct plaintiff in the case, a significant proportion of your tax liability in the previous year may effectively be extinguished. In its place, a very large amount of accounts receivable will be presented to you by the U.S. Treasury.

How does "Liquidation" impact your refund eligibility?

The term liquidation in customs law is the process of the entry of a duty having become final, usually after 314 days following import. Typically, an entry after being liquidated is considered final unless any formal protest is registered within 180 days. Nonetheless, the 2026 CIT judgments have opened a special route in the refunding of IEEPA.

The court has suggested that, as these tariffs are being targeted due to constitutional reasons, the government might end up having to refund past shipments along with interest, as well as entry, even to older shipments that would otherwise be considered closed.

Should you still file a formal Protest under Section 1514?

Although the CIT is promising on its part about automatic or court-ordered refunds, legal experts would have a belt and suspenders approach. To ensure that the tax risk is reduced, the businesses are still supposed to submit the Section 1514 Protests in case of any liquidated entries. Experienced IRS tax experts (a former IRS tax agent, a former auditor, and experienced tax relief lawyers from San Diego) who can file under section 1514. 

This will keep your personal right to a refund, no matter what the federal government decides to do with the greater payout procedure. The anticipated increased workload coming in 2026, with the CBP implementing an electronic refund system through the Automated Commercial Environment (ACE) portal, has intensified the need to make digital record-keeping more significant than ever.

Conclusion

The IEEPA decision of the Supreme Court is the historic rebalancing of trade and tax authority. Any decision against the administration would initiate an instant liquidity phenomenon in the U.S. businesses, which could restore billions back into the balance sheets of companies.

The procedure of getting your money back, however, will need documentation and an insight into the practices of customs liquidation cycles of returning your business to its rightful portion of the refund.
