If you believe there's a mistake with your refund from the Missouri Department of Revenue, you should initially compare your filed return with the adjustments made on the refund check stub. If the issue is still unresolved, you're advised to submit a written inquiry explaining the discrepancy. Include a copy of the refund check stub and any additional supporting documents. Afterward, it is necessary to wait for response as they review the circumstances. Please be aware that during busy times, this process might take several weeks.
