Mississippi tax – Mississippi’s 2025 tax filing and payment deadlines have been extended to June 8, 2026, after Winter Storm Fern and FEMA disaster relief. The update covers many individual and business obligations, including specific IRS deadlines and abated penalties tied to
For a lot of people in Mississippi, the calendar is already tense. And now, the deadline just moved—again—because Winter Storm Fern left power out for thousands.
The Mississippi Department of Revenue and the Internal Revenue Service announced that residents in the Magnolia State received extensions tied to the storm relief. The new combined state and federal deadline is June 8, 2026.
The shift covers filing individual and business tax returns and making tax payments. The reasoning traces back to a disaster declaration issued after a severe winter ice storm knocked out power to thousands in January. By late February, officials estimated the storm caused about $107 million in damages.
Rodney Foushee, who handles IRS media relations for North Carolina, South Carolina, Alabama, Arkansas, Mississippi and Tennessee, said in April that the relief applies to all 82 Mississippi counties.
Under the IRS extension, the expanded window includes all other IRS deadlines that fell between Jan. 23, when the winter storm started, and Monday, June 8. That includes “affected quarterly payroll and certain excise tax returns normally due on Feb. 2, 2026, and April 30, 2026.”
The IRS also addressed penalties for payroll and excise tax deposits. Penalties on payroll and excise tax deposits due on or after Jan. 23 and before Feb. 9 will be abated if the tax deposits were made by Feb. 9, the IRS wrote.
Mississippi’s state deadline moved to June 8 for a defined set of obligations. The Mississippi Department of Revenue said the deadline change includes:
• individual income tax returns
• corporate income and franchise tax return
• pass-through entity tax returns
• quarterly estimated payments that were originally due in this period
The DOR added that the extension does not automatically apply to any other tax types or payments due on prior liabilities.
The state said it will work with people who live outside Mississippi but had business records, books, or tax professionals who work in the affected area.
If you’re not sure whether your situation falls inside the extension—or you already received a penalty notice—Mississippi residents can call the Mississippi Department of Revenue at 601-923-7700.
The tax deadline news lands in a year when Mississippi’s tax system itself is changing. The Mississippi Legislature agreed to eliminate the state income tax in 2025, and Gov. Tate Reeves signed the measure into law. But it isn’t immediate across the board.
The state will phase out its income tax, a process that could take up to a decade for it to be fully gone. Mississippi will have a 4% tax rate by fiscal year 2027, and it should be at 3% by 2030. After 2031, cuts will be activated by triggers built into the language of the law passed in 2025.
That 2025 law also cut sales tax on groceries by 2%. It was designed to hike the gas tax by nine cents over three years to boost infrastructure funds.
As the new June 8 date approaches, the practical advice from the Mississippi Department of Revenue remains simple: the agency encourages people who can to file electronically, and the most common paper return forms are also available online.
For those waiting on refunds, Mississippi taxpayers can check status online at tap.dor.ms.gov. The site requires an ID type and number, along with the refund amount.
The storm didn’t just dim lights in January. It disrupted records, routines, and deadlines. Now, with June 8, 2026 in place, Mississippi taxpayers have a clear date to aim for—while the state continues its longer-term shift away from income taxes.

So June 8 now? I guess taxes are forever delayed lol.
My cousin said it’s automatically June 8 for everyone which sounds fake but maybe not? Like do I still owe if I didn’t file yet? I’m confused.
They say it’s for “all 82 counties” but I swear some towns still had power by then. So if my buddy wasn’t out long, does he still get the same extension or nah? Also the excise tax thing sounds like car stuff??
Winter Storm Fern happened and FEMA paperwork and now the IRS is changing dates again… meanwhile people like me are still getting bills. I read that penalties get abated if deposits were made by Feb 9, which is good I guess, but what if you already got charged interest? Does June 8 fix that or is it just for filing not paying??
