Mississippi completed a landmark multi-year income tax reform in 2026, delivering one of the lowest flat income tax rates in the South. Under House Bill 1733 (passed 2022), Mississippi phased down its top income tax rate from 5% in 2023 to 4.7% in 2024, then 4.4% in 2025, reaching a flat 4% by January 1, 2026. Simultaneously, the former 4% bracket on income $5,000–$10,000 was eliminated, creating a permanent zero-rate band on the first $10,000 of taxable income.
The result for 2026 is a clean, two-tier structure: 0% on the first $10,000, and 4% on everything above — after a $2,300 standard deduction and $6,000 personal exemption. At $100,000 income, a single filer pays approximately $3,268 in Mississippi state tax (3.27% effective rate). For retirees, Mississippi is even more attractive: the state exempts all Social Security income, all public and private pension income, all IRA withdrawals, and all 401(k) distributions — making it one of the most comprehensive retirement income exemption regimes in the United States.
Mississippi's income tax rate in 2026 is the end point of a four-year legislative reform. House Bill 1733, signed in 2022, set a schedule to reduce and simplify the state's graduated income tax:
The first $10,000 of Mississippi taxable income has been exempt (0% rate) since 2023, when the old 4% bracket was abolished. Combined with the standard deduction and personal exemption, a meaningful amount of income escapes taxation entirely before the 4% rate applies.
The table below shows effective state income tax at various income levels for a single filer in 2026:
| Gross Income | After Deductions | Tax at 4% | Effective Rate |
|---|---|---|---|
| $40,000 | $31,700 | $868 | 2.17% |
| $60,000 | $51,700 | $1,668 | 2.78% |
| $75,000 | $66,700 | $2,268 | 3.02% |
| $100,000 | $91,700 | $3,268 | 3.27% |
| $150,000 | $141,700 | $5,268 | 3.51% |
| $250,000 | $241,700 | $9,268 | 3.71% |
Note: After deductions column reflects $2,300 standard deduction + $6,000 personal exemption; tax is calculated as 0% on first $10,000 + 4% on the remainder. Effective rate = Mississippi tax divided by gross income.
Unlike some flat-tax states that offer only a personal exemption, Mississippi uses both a standard deduction and a personal exemption, stacked together to reduce taxable income before the rate schedule applies.
For 2026, the deduction and exemption amounts are:
A single filer with no dependents reduces their taxable income by $8,300 before the rate schedule kicks in. A married couple with two children reduces income by $19,600 ($4,600 + $12,000 + $3,000).
Combined with the zero-rate band on the first $10,000 of taxable income, a single filer effectively shields the first $18,300 of gross income from any Mississippi tax — making the system more progressive in practice than the flat 4% rate implies.
Mississippi stands apart from nearly every other state in the depth of its retirement income exemption. The state exempts all of the following from state income tax:
In practice, a retired couple in Mississippi living entirely on Social Security, a private pension, and IRA withdrawals pays zero Mississippi state income tax — regardless of the total amount received. This is a dramatically different outcome than in states like Rhode Island or Minnesota that apply income thresholds or phase-outs on retirement income exemptions.
This makes Mississippi one of only a handful of states to offer a near-total retirement income exemption covering both public and private sources.
Mississippi's closest comparisons for potential retirees and relocators are neighboring Tennessee and Texas — both states with no income tax. The comparison is more nuanced than it first appears.
Mississippi vs Tennessee (no income tax):
Mississippi vs Texas (no income tax):
For working-age filers with $100,000 earned income, Mississippi costs $3,268 more annually in income tax than Tennessee or Texas. But for retirees, Mississippi's total tax burden is often competitive with — or lower than — both states, once property taxes are factored in against the Texas comparison.
Mississippi's combination of retirement income exemptions and low overall rates creates a compelling tax profile for retirees. Consider a retired couple with the following income:
In Mississippi, every dollar of that $100,000 is exempt from state income tax. The couple pays $0 in Mississippi state income tax.
Compare that to:
Mississippi's property tax rate of ~0.79% is moderate, adding approximately $2,370/year on a $300,000 home. But the zero income tax on all retirement income means Mississippi retirees consistently pay less total state and local tax than retirees in most northern and western states.
Kiplinger, MoneyTalksNews, and similar personal finance publications have regularly ranked Mississippi among the top 10 most tax-friendly states for retirees, primarily due to the comprehensive retirement income exemption.
Mississippi's effective property tax rate averages approximately 0.79% — moderate compared to the US average of around 1.1%. On a $250,000 home, that's roughly $1,975/year; on a $300,000 home, approximately $2,370/year.
Mississippi provides a homestead exemption for owner-occupied primary residences. The exemption reduces the assessed value of the home for property tax purposes. Additionally, homeowners aged 65 and older who meet income requirements may qualify for additional property tax relief under Mississippi's Homestead Exemption for Senior Citizens.
Property tax rates vary by county and municipality. Jackson (Hinds County) and DeSoto County (suburban Memphis) tend to have higher effective rates than more rural areas. However, even in higher-rate counties, Mississippi's property taxes remain significantly lower than comparable counties in Illinois, New Jersey, or New York.
Mississippi's 7% state sales tax rate is one of the highest single-state rates in the United States. Only California (7.25% state rate) exceeds it among major states. Unlike most states that exempt groceries from sales tax, Mississippi taxes most grocery items at the full 7% rate — a policy that disproportionately affects lower-income households who spend a higher share of income on food.
There are limited exceptions: prescription drugs are exempt, and certain agricultural inputs are exempt. But everyday supermarket purchases — bread, milk, vegetables, meat — are taxed at 7%.
Mississippi does not have significant local sales tax additions (unlike Texas or Louisiana, where local rates can push combined sales tax above 9–10%). Most Mississippi localities charge the 7% state rate with minimal or no additions, keeping the combined rate at or near 7%.
On $40,000 in annual taxable consumer spending, a Mississippi household pays approximately $2,800 in sales taxes per year — a meaningful burden, particularly for families. This is the primary offset to Mississippi's relatively low income tax rates.
The grocery tax has been a recurring topic in the Mississippi legislature. As of 2026, proposals to reduce or eliminate the grocery tax have not passed, though the issue remains politically active.
Unlike some states where cities levy their own income tax on top of the state rate — such as New York City (up to 3.876%), Philadelphia (3.75%), or Detroit (2.4%) — Mississippi has no local income taxes. The 4% flat rate is the total state income tax burden; no city or county in Mississippi imposes an additional income tax.
This simplifies tax filing considerably. Mississippi residents file a single state income tax return with the Mississippi Department of Revenue. There is no city income tax return, no county income tax, and no special district income tax.
For workers who live in one Mississippi city and work in another, or who commute from Tennessee or Alabama into Mississippi, there is no local income tax layer to navigate. The only state-level complication is reciprocity agreements with neighboring states, which Mississippi handles through standard non-resident credit provisions on the state return.
The foundation of Mississippi's 2026 tax structure is House Bill 1733, signed by Governor Tate Reeves in April 2022. This legislation set in motion the most significant change to Mississippi's income tax in decades.
Before HB 1733, Mississippi used a graduated three-bracket system:
HB 1733 phased out the two lower brackets entirely (effective 2022–2023) and began systematically reducing the 5% top rate:
The legislation also includes a trigger mechanism that could reduce the rate further toward 3% in future years if state revenue growth targets are met. Mississippi lawmakers have discussed the long-term goal of eventually eliminating the income tax entirely, though no legislation to that effect has passed as of mid-2026.
The reform was designed to make Mississippi more competitive with neighboring Tennessee (no income tax) and attract both businesses and retirees to the state.
