Mississippi Income Tax Guide 2026: 4% Rate, Retirement Exemptions & Rules

Mississippi’s income tax rate is 4% in 2026 (on income above $10,000) — the result of a sweeping 2022 tax reform, and further extended by 2025 legislation, that has progressively cut the rate from 5% down in annual steps, with a path toward 3% by 2030. Combined with its extraordinary retirement income exemptions — Social Security, pensions, 401(k) and IRA withdrawals are all exempt — Mississippi is one of the most tax-friendly states for retirees in the South. The tradeoff is a 7% state sales tax, one of the highest in the country.

Mississippi Income Tax Rate 2026

Mississippi transitioned from a graduated system to an effective flat rate through 2022 reform legislation (HB 531), and 2025 legislation extended the phase-down further:

Further reductions beyond 2026 are contingent on the state meeting revenue-growth and spending-constraint triggers written into the legislation.

Mississippi Personal Exemption and Standard Deduction

Mississippi income tax does not apply to all income — the personal exemption and standard deduction carve out a meaningful portion of income that is not taxed at all. Confirm current-year amounts with the Mississippi Department of Revenue, as these were the last confirmed figures and may be periodically adjusted:

Mississippi Retirement Income: Broadly Exempt

Mississippi’s retirement income tax treatment is among the most generous in the United States. The state exempts a wide range of retirement income that other states tax:

This is not a partial exemption with income caps — Mississippi generally excludes the entire amount of these income types from state taxable income. A retiree living on Social Security plus IRA distributions plus a pension effectively pays zero Mississippi income tax on that income, regardless of the total amount.

Mississippi vs. Southern States

Mississippi can’t compete with Florida and Tennessee on raw rate, but its complete exemption of retirement income eliminates the effective state tax burden for most retirees — making it similar in practice to a no-income-tax state for retired households.

Mississippi Property Tax

Mississippi property taxes are low by national standards. Confirm the current average effective rate with the Tax Foundation or Mississippi Department of Revenue, as this figure was not independently re-verified this session. Property is assessed at varying percentages of market value depending on property classification (single-family residential is historically assessed at a lower percentage than commercial/industrial property) — confirm current assessment ratios.

Homestead Exemption

Mississippi’s standard homestead exemption reduces the assessed value used to calculate property taxes for owner-occupants. Confirm current exemption amounts with the Mississippi Department of Revenue.

Mississippi Sales Tax

Mississippi’s 7% state sales tax is one of the highest in the nation and applies to most purchases including groceries:

Local governments can add sales taxes, bringing total rates in some cities to 8% or higher.

The grocery tax is a meaningful cost for families and lower-income retirees — and is one of the most-cited criticisms of Mississippi’s tax structure.

Mississippi Capital Gains

Mississippi taxes capital gains as ordinary income at the same rate as other income. There is no preferential rate for long-term capital gains.

Local Income Taxes

Mississippi has no local income taxes. The only income tax is the state-level rate.

Filing Requirements

Filing deadline: April 15. Mississippi conforms to the federal extension rules.

Electronic filing is available free through the Mississippi Department of Revenue portal.

Who Should Consider Mississippi?

Good fit for:

• Retirees drawing income from pensions, Social Security, and retirement accounts — effective state tax rate near zero
• Military retirees — full exemption on military retirement pay
• Those moving from high-tax states (CA, NY, IL, NJ) seeking low cost of living
• Homeowners — property taxes are well below national average

Consider before moving:

• 7% sales tax on groceries is a recurring cost that hits all income levels
• Combined state + local sales taxes of 7–8% can offset income tax savings for high-spending households
• Confirm current job market and public service conditions for your specific area of interest
