MO Tax Extension

Extension FormMissouri Extension InstructionsHow to File

Form MO-60

If you receive an extension of time to file your federal tax return, you will automatically be granted an extension of time to file your MO state return (not the time to pay taxes owed). Attach a copy of your federal extension (Federal Form 4868 or 2688) with your state tax return when you file. If you anticipate receiving a refund or you do not expect to owe additional taxes, you may not be required to file a MO state tax extension.

If you did not file a federal tax extension and you owe tax, file MO state extension Form MO-60 on or before the due date of the MO state return. A copy of of Form MO-60 must be enclosed with the MO state return when filed.

If you want a MO state tax extension exceeding the federal automatic extension period, you must file Form MO-60 on or before the end of the Federal automatic extension period.

If you expect to owe income tax, include Form MO-60 with your payment by the original tax return deadline. Otherwise, a 5% additional tax penalty will apply if the tax is not paid by the original due date, provided your return is filed by the extension deadline.
