Mississippi's Extension Tied to Federal Approval

Mississippi grants an automatic six-month extension for filing personal income tax returns to taxpayers who have been approved for a federal extension by the IRS. The Mississippi Department of Revenue mirrors the federal timeline, moving the state filing deadline from April 15, 2026, to October 15, 2026. No separate Mississippi extension application is required.

Important: Attach Form 4868 When You File Your Return

When you file your Mississippi return by October 15, attach a copy of your federal Form 4868 to the return. Keep a copy available when preparing your Mississippi return.

Payment Is Still Due by April 15

Mississippi's extension applies only to filing—not to paying taxes. Any Mississippi income tax owed must be paid by April 15, 2026, to avoid penalties and interest.

How to Make Extension Payments

ACH Debit (TAP): Visit www.dor.ms.gov and click TAP (Taxpayer Access Point).
Credit Card / E-Check: Visit www.ms.gov/dor/quickpay. Convenience fee charged by the service provider.
