Missouri Income Tax Extension

Option 1: If you do not owe Missouri income taxes or expect a MO tax refund by the tax deadline, you do not have to prepare and file a MO tax extension. In case you expect a MO tax refund, you will need to file or e-File your MO tax return in order to receive your tax refund money.

Option 2: eFiled a Federal Extension? If you do not owe Missouri income taxes or expect a tax refund by the tax deadline, your accepted federal extension will be honored as a state extension, and you do not have to mail in Form MO-60.

Option 1: Pay all or some of your Missouri income taxes online via: Missouri Department of Revenue.

Option 2: If you owe MO income taxes, you will either have to submit a MO tax return or extension by the tax deadline in order to avoid late filing penalties. You can only eFile and IRS tax extension, but not a Missouri extension. The tax extension will only avoid late filing penalties until the October deadline.
Note: Unless you pay all your Taxes or eFile your tax return by the October deadline, the late filing penalties will start again after that deadline.

Option 3: Complete Form MO-60, include a Check or Money Order, and mail both to the address on Form MO-60. Important: Even if you filed an extension, you will still need to file your MO tax return either via eFile or by paper by the October deadline.
