What are Missouri estimated payments or extension payments?

Estimated Payments: If you didn't have enough Missouri income taxes withheld from your earnings during 2025, you may have made estimated tax payments. These payments count as a credit toward your 2025 Missouri tax liability.

Extension Payment: If you filed for an extension to submit your income tax return, you may have made a tax payment with that extension. This payment counts as a credit toward your 2025 Missouri tax liability.
