In the 2026 tax filing season, the Missouri Department of Revenue has processed more than three million tax returns, issuing over 1.8 million refunds totaling more than one billion dollars. By statute, the department has 45 days from the date of mailing to process and issue the individual refund before interest is due. Currently, 93% of taxpayers file electronically, which significantly reduces refund turnaround time. Returns sent by mail can take up to six weeks to process, while electronically filed returns typically take about six days.

Tax filers who have not received their expected refund within these timeframes are encouraged to check the status of their refund through DOR’s Missouri Return Tracker.
