The TCJA didn’t change the research credit, but it has an impact on the credit. Previously, corporations subject to alternative minimum tax (AMT) couldn’t offset the research credit against AMT liability, which erased the credit’s current benefits. By eliminating corporate AMT, the TCJA removed this obstacle. Pass-through businesses can still claim the credit against AMT if their average gross receipts are $50 million or less. And qualifying start-ups without taxable income can still claim the credit against up to $250,000 in payroll taxes. Contact us for details.
