NEW YORK (AP) — A refund system for businesses that paid tariffs imposed by former President Donald Trump without constitutional authority will begin on Monday. U.S. Customs and Border Protection will manage the online portal where importers and brokers can start claiming their refunds from 8 a.m. onwards.

This initiative comes after the U.S. Supreme Court ruled against the constitutionality of the tariffs. Businesses must declare their goods and the tariffs they paid to claim refunds, which could take 60-90 days to process.

The government has announced that refunds will be processed in phases, focusing first on more recent payments. Companies will face various challenges, including ensuring accurate documentation to prevent claim rejections.

Small businesses, eager to see their refunds, are preparing for this opportunity, while the potential for consumers to also receive refunds depends on how companies choose to handle the reimbursements. Some class-action lawsuits against big retailers may lead to consumers receiving some funds, particularly if they were taxed at the point of sale.

As the deadline approaches, patience and accuracy will be vital during this refund process.
