Mississippi's income tax is declining: from 5% (2021) toward 4.4% (2025) with a legislated path toward eventual elimination under Governor Tate Reeves's agenda. More importantly, Mississippi broadly exempts retirement income โ pensions, IRA distributions, 401(k) withdrawals, and Social Security are all exempt from Mississippi income tax. Military retirement is fully exempt. Mississippi has the lowest effective property tax rate in the US (~0.63%) and the lowest cost of living of any state. For retirees, Mississippi is already effectively a zero-income-tax state for most retirement income.

Key Facts
Mississippi Income Tax Rate (2025)
Single flat rate of 4.4% on taxable income above the $10,000 exemption threshold (2025, under phase-down from SB 2358). Further reductions legislated: 4.0% in 2026. Mississippi's long-term goal is income tax elimination, though full elimination timeline is not yet legislated.
Retirement Income Exemption
Mississippi broadly exempts retirement income from state income tax: qualified pension income, IRA distributions (traditional and Roth), 401(k) and 403(b) distributions, annuity income from retirement plans, and federal and state government pension income are all exempt. This is one of the most comprehensive retirement income exemptions of any state.
Social Security Exemption
Mississippi does NOT tax Social Security benefits โ 100% exempt at all income levels.
Military Retirement Exemption
Mississippi fully exempts military retirement income from state income tax.
No Estate or Inheritance Tax
Mississippi has no estate tax and no inheritance tax.
Property Tax
Mississippi property tax effective rate approximately 0.63% โ among the lowest in the United States. Homestead exemption of $300 for owner-occupied primary residences. Additional exemptions for elderly and disabled homeowners. Mississippi property taxes are low even within the low-tax Southern region.
Introduction
Mississippi is consistently ranked as the state with the lowest cost of living in the United States, and its tax structure increasingly complements that advantage. Mississippi's income tax reform (SB 2358, 2022) eliminated lower brackets and set a declining rate path. Crucially, Mississippi has among the most generous retirement income exemptions in any state: pensions, IRA distributions, 401(k) withdrawals, and Social Security are all broadly exempt โ meaning most retirees pay zero Mississippi income tax. For working-age residents, the declining 4.4% rate is moderate. Moving from Mississippi to Florida or Tennessee saves only on wages and non-retirement investment income. This guide covers Mississippi's tax structure and what departing residents need to know.
Section 01
Mississippi's Retirement-Friendly Tax Structure
Mississippi is one of the most retirement-friendly tax environments in the South:
The Retirement Income Exemption: What's Covered
Mississippi's retirement income exemption covers virtually all retirement income sources:
Pensions: all qualified pension distributions (government and private)
IRA distributions: traditional IRA and Roth IRA distributions
401(k) and 403(b): qualified plan distributions
Annuities: distributions from qualified annuities and retirement annuities
Federal pensions: CSRS and FERS fully exempt
Social Security: fully exempt at all income levels
Military retirement: fully exempt
What is NOT exempt: wages, self-employment income, rental income, and non-retirement investment income (capital gains, dividends, interest).
Practical Impact for Retirees
A Mississippi retiree at age 65 with $80,000 in combined income: $25,000 SS (exempt) + $35,000 IRA distributions (exempt) + $20,000 pension (exempt) = $0 Mississippi income tax. The same retiree needs to earn wages or have substantial non-retirement investment income to have any Mississippi tax liability.
Mississippi vs Tennessee for Retirees
Tennessee has no income tax at all (Hall Tax eliminated 2022). Mississippi taxes wages and investment income (dividends, capital gains, interest) at 4.4%. For a retiree with ONLY retirement income, there is no difference โ both states = $0. For a retiree with significant capital gains (e.g., selling a vacation home), Tennessee is slightly better: $0 vs Mississippi's 4.4% on the capital gain.
Cost of Living Context
Mississippi's median home price of approximately $160,000โ$200,000 (varies by metro area) vs national median of approximately $400,000 means property tax bills at 0.63% effective rate are approximately $1,000โ1,260/year. Jackson, Biloxi, Gulfport, Hattiesburg, and Tupelo all offer significantly lower housing costs than comparable cities in neighboring states or major metros.
Section 02
Mississippi Residency Exit Rules
Mississippi uses standard domicile-based residency:
Mississippi Residency
Mississippi defines a resident as someone domiciled in Mississippi. Mississippi uses common law domicile principles โ no published specific day-count threshold beyond domicile. To exit Mississippi residency: establish domicile in the new state (driver's license, voter registration, vehicle registration, estate documents). Mississippi does not have a reputation for aggressive post-departure residency audits.
Who Benefits from Moving OUT of Mississippi?
Given Mississippi's broad retirement income exemption, most retirees do NOT have a strong financial motivation to move out of Mississippi for tax reasons. The candidates who do benefit from moving to a no-income-tax state:
High earners with substantial wages (above $100,000): save 4.4% on wages above the $10,000 exemption
Business owners with significant pass-through income (above the threshold): save 4.4% on pass-through income
Investors with large capital gains events (business sale, stock): save 4.4%
For retired Mississippians, moving to Florida or Tennessee primarily produces lifestyle changes, not significant tax savings.

Will Mississippi actually eliminate its income tax?
Mississippi has a stated legislative goal of income tax elimination, driven by Governor Tate Reeves and the Republican-controlled legislature. The SB 2358 reform set a declining rate path (5% โ 4.4% โ 4.0% โ future reductions), but full elimination has not been fully legislated with a specific timeline. The challenge: Mississippi's income tax generates approximately $1.8โ2.0 billion annually โ a substantial portion of state revenue. Full elimination would require either significant spending cuts, revenue replacement (higher sales tax โ Mississippi already has a 7% state sales tax), or federal revenue increases. As of April 2026, the declining rate path continues but full elimination in the near term remains a legislative aspiration rather than a guaranteed outcome. Residents should monitor Mississippi legislative sessions annually.
Q
Does Mississippi's retirement income exemption cover IRA-to-Roth conversions?
Mississippi's retirement income exemption covers qualified retirement plan distributions. A traditional IRA-to-Roth conversion is treated as a distribution from the traditional IRA โ which qualifies for the Mississippi exemption if it is a qualified retirement plan distribution. The Mississippi exemption language covers 'retirement benefits' broadly, including IRA distributions. This means Mississippi residents doing large Roth conversions may not owe Mississippi income tax on the conversion amount โ a significant planning advantage vs states that tax IRA distributions as ordinary income. Federal income tax still applies to the traditional-to-Roth conversion amount. For high-income individuals planning Roth conversion strategies, Mississippi's exemption means the state component of the conversion tax cost is potentially zero.
Q
How does Mississippi compare to Alabama for retirees?
Mississippi vs Alabama for retirees: Both are excellent retirement tax states. Mississippi has a broadly comprehensive retirement income exemption (all pension/IRA/401(k)/SS exempt); Alabama has full Social Security exemption, full military retirement exemption, full federal civil service pension exemption, but taxes private IRA and 401(k) distributions (partially, with a modest $6,000 age-65+ exemption). Mississippi is slightly better for retirees with significant IRA/401(k) distributions; Alabama is better for federal civilian or military retirees specifically. Property tax: Mississippi 0.63% vs Alabama 0.41% โ Alabama is significantly lower. Cost of living: both are among the lowest nationally; Mississippi is slightly lower overall. For a military retiree: both are excellent (fully exempt). For a private sector retiree with large IRA distributions: Mississippi is better due to the broader retirement exemption.
