Federal and state tax filing deadline for Mississippi is days away

America’s wealth gap is exploding. Should the rich pay more?
Income inequality is soaring in the U.S., sparking a national debate: Should the super‑rich face a wealth tax?
Haven’t filed your 2025 taxes yet? It’s not too late in Mississippi, but time is running out.
The Mississippi Department of Revenue and Internal Revenue Service announced in April that all Magnolia State residents would get extensions. The state and federal deadline shifts are part of relief for Winter Storm Fern.
The new deadline is June 8, 2026. It includes filing individual and business tax returns and making tax payments.
The decisions followed a disaster declaration from Federal Emergency Management Agency. A severe winter ice storm knocked out power to thousands in January. As of late February, it was estimated to have caused about $107 million in damages.
IRS deadline extended for Mississippi taxpayers
Rodney Foushee handles IRS media relations for North Carolina, South Carolina, Alabama, Arkansas, Mississippi and Tennessee. He said in April that the relief applies to all 82 Mississippi counties.
It also covered 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.”
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 state tax deadline moved to June 8
Mississippi DOR said the deadline change includes:
- individual income tax returns
- corporate income and franchise tax returns
- pass-through entity tax returns
- quarterly estimated payments that were originally due in this period
“The extension does not automatically apply to any other tax types or payments due on prior liabilities,” the DOR said.
The state will work with people who live outside the state but had business records, books or tax professionals who work in the affected area.
Call the Mississippi Department of Revenue at 601-923-7700 if you need an extension or get a penalty notice.
Is Mississippi getting rid of income tax?
The Mississippi Legislature agreed to eliminate the state income tax in 2025. Gov. Tate Reeves signed it into law. But it wasn’t automatic.
The state will phase out its income tax, but it could take up to a decade for it to be fully gone.
The state will have a 4% tax rate by fiscal year 2027. It should be at 3% by 2030. After 2031, cuts will be activated by triggers set up in the language of the law passed in 2025.
The move 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.
