You can track your refund at the Missouri Return/Refund Tracker page. If you still have questions about your state tax refund, contact the Missouri Department of Revenue.
Statement from the Missouri Department of Revenue: Generally, the timeframe for issuing refunds depends on when the return is filed and the incoming volumes. For returns filed in January with no review required, refunds can be issued within a week. However, refunds from returns filed in April can take longer. The timing of refunds is also affected by the Department’s measures to prevent identity theft and refund fraud. Refunds will only be issued when the Department has taken reasonable steps to ensure that the individuals claiming the refunds are not using stolen identities.
