Mississippi State Income Tax in 2025: A Guide

Mississippi’s straightforward 4.7% state income tax rate for the 2024 tax year (the taxes you file in 2025) offers simplicity for taxpayers, especially compared to states that use multiple income tax brackets. With this flat tax rate, Magnolia State taxpayers pay the same percentage regardless of income. This makes calculating your taxes and filing them more predictable. 

Whether you live in The Magnolia state or earn income there, the state’s uniform tax rate streamlines the process and eliminates tax preparation guesswork.  

Here’s what you need to know about filing taxes in Mississippi in 2025.

How much is Mississippi state income tax?

For taxes filed in 2025, Mississippi’s state income tax rate will be 4.4% on taxable income over $10,000. The first $10,000 of taxable income will remain taxed at 0%. This is part of a phased tax reduction plan. 

While Mississippi isn’t eliminating state income tax entirely, it is gradually reducing rates. The plan aims to lower the top rate to 4% by 2026, but complete elimination has not been enacted.

Who has to file Mississippi state income tax?

All Mississippi residents or those earning income in the state that exceeds allowable deductions and exemptions must file a state income tax return. Nonresidents and part-year residents who earn Mississippi income may also need to file. 

If you’re not required to file but receive a W-2 showing Mississippi tax withheld, filing a return ensures you can claim a refund for those withholdings.  

Unless you file for an extension, the due date to file Mississippi state tax returns is April 15, 2025, the same as the federal deadline.

How Mississippi residency impacts tax filing

Residency plays a key role in how Mississippi taxes your income. Residents maintain a home or apartment in the state or exercise citizenship rights like voting or claiming a homestead exemption. Even if you temporarily leave the state, you can be considered a resident until you officially establish residency elsewhere. 

The following table outlines each residency status, who qualifies, and how Mississippi taxes income for each group: 

Residency status	Definition	How Mississippi taxes income
Resident	Lived in Mississippi all year or permanently maintain a home there	Taxes all income earned during the tax year.
Part-year resident	Moved into or out of Mississippi during the year.	Taxes income earned while living in Mississippi and prorates deductions.
Nonresident	Lived outside Mississippi but earned income from Mississippi sources.	Taxes only income earned in Mississippi.

Other income tax considerations in Mississippi

Mississippi taxes certain kinds of income differently and offers specific exclusions or exemptions in some cases. The following list breaks down retirement, investment, and Social Security income and how they’re treated under state tax law: 

• Retirement and pension income: Retirement income, pensions, and annuities are tax-free if retirement plan requirements are met. Early distributions aren’t considered retirement income and may be taxable. 
• Investment income: Capital gains are taxed as individual income. 
• Social Security income: Mississippi doesn’t tax Social Security, Railroad Retirement, Veterans’ benefits, or workers’ compensation claims. 
• Military income: Active-duty military pay is taxed based on your home of record. Hazardous duty pay and some National Guard/reserve income are exempt. If you entered the military in Mississippi, you’re presumed to be a resident. Other exemptions and qualifications may apply.

Mississippi state tax credits
