Mississippi Paycheck Calculator – Current Tax Year
Mississippi is closing in on becoming the 10th state with no personal income tax, but it isn’t there yet. Right now there’s a single 4% rate that only touches income past the first $10,000, and that exemption line works a little differently than people expect when they’re married. Here’s the math your actual paycheck runs on.
Test a Raise, New Job, or Pay Cut
Because Mississippi’s rate is one flat number above the exemption line, you can see exactly what a raise costs you here, no bracket guesswork involved.
The $10,000 Line That Trips Up Married Filers
Most people assume the rules double once you get married, but Mississippi’s $10,000 tax-free threshold doesn’t work that way. A married couple filing jointly still shares one combined $10,000 exemption, not two separate ones added together. It’s a small detail, but it surprises a lot of newly married Mississippi residents who expect the same doubling pattern they’ve seen with federal brackets or other state deductions. Once that shared $10,000 is used up, every additional dollar of joint taxable income is taxed at the same flat rate as everyone else’s.
Where Mississippi’s Rate Actually Stands Today
The state spent years sanding down what used to be a three-tier system: 3% on the first slice of income, 4% on the next, and 5% above that. Lawmakers eliminated the bottom two tiers entirely between 2022 and 2023, leaving one number, and that number has kept dropping since: 5% in 2023, 4.7% in 2024, 4.4% in 2025, and 4% for the current tax year. Governor Tate Reeves signed legislation in March 2025 mapping a further descent toward 3% by 2030, with language built in for the rate to keep falling toward zero after that, assuming the state’s finances cooperate.
- One number, not a bracket table – 4% applies to everything above $10,000, regardless of how much you earn beyond that.
- The $10,000 exemption is shared, not doubled – joint filers split one exemption amount rather than each getting their own.
- Standard deduction and personal exemption stack separately – $2,300 to $4,600 depending on filing status, plus $6,000 to $12,000 in personal exemptions, before the $10,000 zero-tax band even applies.
- No city or county income tax – Mississippi keeps that authority entirely at the state level.
- Almost all retirement income is untouched – Social Security, pensions, qualifying 401(k) distributions, and veterans’ benefits stay out of state taxation entirely.
| Deduction | Rate | Applies To |
|---|---|---|
| Federal Income Tax | 10%-37% | Taxable income after federal deductions |
| Mississippi State Tax | 4% flat | Taxable income above a shared $10,000 exemption |
| Local/Municipal Tax | 0% | Not authorized anywhere in Mississippi |
| Social Security | 6.2% | Income up to the annual wage base |
| Medicare | 1.45% | All earned income, plus 0.9% for high earners |
How Real Is the Promise of Zero Income Tax by 2030?
This is where it gets interesting, and where a lot of headlines oversimplify. The legislation ties future rate cuts to a revenue trigger formula, meaning the rate only keeps falling if state tax collections grow fast enough relative to spending. Independent budget analysts who dug into the actual trigger math found that, applied correctly to the last decade of Mississippi’s revenue history, the formula would have fired in only a couple of those years, not nearly often enough to hit zero by the dates lawmakers have publicly touted. Their more conservative estimate puts full elimination closer to 2040 than 2030, assuming nothing else changes. None of that affects what you owe this year, but it’s worth knowing before you treat “Mississippi is going income-tax-free” as a settled fact rather than a goal still riding on future budget performance.
Mississippi Paycheck FAQs
What is Mississippi’s current income tax rate?
For the current tax year, Mississippi applies a flat 4% rate to taxable income above a $10,000 exemption, down from 4.4% the prior year as part of an ongoing legislative reduction schedule.
Does the $10,000 exemption double for married couples?
No, married couples filing jointly share one combined $10,000 exemption rather than each spouse receiving a separate one.
Will Mississippi eliminate its income tax entirely?
Legislation signed in March 2025 sets a path toward a 3% rate by 2030 and potential full elimination afterward, but the later reductions depend on revenue triggers, and independent analysis suggests the realistic timeline could extend well past 2030.

This calculator provides general estimates based on Mississippi’s current flat 4% rate, the shared $10,000 exemption, standard deduction and personal exemption amounts by filing status, the per-dependent exemption, standard federal tax brackets, and current FICA rates, for informational purposes only. Mississippi’s rate is subject to further reduction under revenue-triggered legislation passed in 2025, and the realistic pace of that reduction is genuinely uncertain.
