Modifies provisions relating to the "Missouri Working Family Tax Credit Act", making the tax credit refundable

HB 1739 modifies Missouri's Working Family Tax Credit Act to make the state tax credit refundable for eligible low-to-moderate income residents starting in 2027. It allows qualifying taxpayers (those claiming the federal Earned Income Tax Credit) to receive a credit equal to 10% (potentially increasing to 20%) of their federal credit amount, with the refundability change applying only to tax years beginning January 1, 2027, and later. The credit percentage increase to 20% is tied to Missouri's state revenue growth exceeding prior years by $150 million. The bill also requires the state to proactively notify eligible taxpayers who didn't claim the credit and report annual usage statistics.
