Mississippi Extension

If you need more time to file your Mississippi return, Mississippi will allow you the same time that is allowed by your federal extension.

Note, however, that an extension of time to file doesn't extend the time to pay any tax you owe to the state of Mississippi. If you expect to owe tax to Mississippi, you'll need to pay that amount by April 15, 2026, to avoid penalties and interest. You can make an extension payment with Mississippi Form 80-106.
