General Motors is expecting a $500 million tariff refund after the Supreme Court struck down some of President Donald Trump’s most sweeping levies. That’s boosted the Michigan-based auto maker’s outlook for 2026. On Tuesday, GM said it’s now looking to rake in $13.5 billion to $15.5 billion in earnings before interest and taxes this year — up from previous forecasts of $13 billion to $15 billion. Companies big and small are seeking refunds on tariffs they paid that the Supreme Court ruled illegal in February.  And on April 20, the Customs and Border Protection agency launched an online system for claims.
