Mississippi taxpayers now have until June 8, 2026, to file individual and business returns and make tax payments after state and federal officials extended the tax filing deadline because of relief tied to Winter Storm Fern. The change covers all 82 Mississippi counties.

The extension is the date taxpayers are searching for now because June 8 is the next confirmed filing and payment deadline, and it applies across the state rather than to just a narrow disaster zone. In April, the Mississippi Department of Revenue and the Internal Revenue Service said the relief would push back the state and federal deadline for people and businesses dealing with the storm’s fallout.

Rodney Foushee said in April that the relief applies to all 82 counties, a detail that matters because it means the deadline did not stop at county lines or depend on where the worst damage hit. The extension also covers other IRS deadlines that fell between Jan. 23 and Monday, June 8, including quarterly payroll and certain excise tax returns that were normally due on Feb. 2, 2026, and April 30, 2026.

There is one limit taxpayers need to keep in mind. The Mississippi Department of Revenue said the extension does not automatically apply to any other tax types or to payments tied to prior liabilities. Payroll and excise tax deposits due on or after Jan. 23 and before Feb. 9 can have penalties abated if the deposits were made by Feb. 9, but that relief does not sweep in every unpaid obligation.

The broader backdrop is a state still dealing with the damage from Winter Storm Fern, which started Jan. 23, 2026, knocked out power to thousands in Mississippi in February and was estimated in late February to have caused about $107 million in damage. The department also said it will work with people who live outside Mississippi but kept business records, books or tax professionals in the affected area. Taxpayers can file electronically, and the most common paper return forms are available online at tap.dor.ms.gov.

That makes June 8 the real deadline to watch. It is the day individual filers, businesses and many storm-affected taxpayers must be ready, even as Mississippi continues a separate long-term plan to phase out the state income tax over up to a decade after the Legislature approved the 2025 law and Gov. Tate Reeves signed it.
