Mississippi Paycheck Calculator 2026 — 4% Flat Tax & Take-Home Pay

Estimate Mississippi take-home pay for 2026 with a flat 4% rate above a $10,000 zero band, the $2,300 standard deduction, FICA and federal withholding — free and instant.

How Mississippi Paychecks Work

1. Federal tax: progressive brackets 10%–37% minus the $16,100 standard deduction (single, 2026) — same as everywhere.
2. FICA: 6.2% Social Security (up to the $184,500 wage base) + 1.45% Medicare — same as everywhere.
3. State tax: 4% flat above a $10,000 zero band. One rate on all Mississippi taxable income above $10,000 — the first $10,000 is taxed at 0%. The $6,000 personal exemption plus a $2,300 standard deduction come off first. House Bill 531 cut the rate to 4% for 2026; House Bill 1 continues the cuts toward 3% by 2030.

Worked Example: $85,000 Single Filer

Mississippi vs Texas vs California on $85,000

The same single filer keeps $65,959.50 in Mississippi against $68,627 in Texas and $64,007 in California. Mississippi's flat 4% costs $103 a paycheck versus the no-tax states — and beats California by $1,952.50 a year on this salary. Model any state in the calculator.

Federal Withholding on a Mississippi Paycheck

Only one income tax touches a Mississippi paycheck: the federal one. Withholding follows the IRS percentage method in Publication 15-T, and three inputs drive it: your filing status, the dependents and credits you claim on Form W-4, and any extra withholding you request. Change any of the three and the same salary produces a different stub, which is why two Mississippi workers earning $85,000 can take home different amounts.

Federal tax is progressive, which means it applies in slices, not to the whole salary at once. Only the dollars inside each bracket are taxed at that bracket's rate, so a single filer's effective rate is always lower than their top marginal rate. The standard deduction then removes a further slice of income from tax entirely before the brackets even start. Pre-tax items shrink the taxable wage base further: 401(k) contributions and health premiums taken pre-tax reduce the wages the percentages apply to, though the exact treatment differs by deduction type, so read your stub labels rather than assuming.

Our US paycheck calculator models this with an editable withholding percentage instead of hard-coding tables that Congress and inflation adjust every year. If you want the precise official arithmetic for the current year, Publication 15-T is the source the payroll industry itself uses.

FICA: the Two Lines That Always Appear

Below the federal line sit two flat deductions that behave nothing like income tax. Social Security takes 6.2% of wages up to the Social Security Administration's annual wage base, a cap it resets every year. Medicare takes 1.45% of all wages with no cap, plus an additional 0.9% on earnings above $200,000 for single filers ($250,000 joint) — those thresholds are set in statute, not adjusted annually. Your employer matches the 6.2% and the 1.45% dollar for dollar; the additional 0.9% is employee-only.

On the $85,000 example: Social Security is $85,000 x 0.062 = $5,270, comfortably below any recent wage-base cap, and Medicare is $85,000 x 0.0145 = $1,232.50. Together with federal withholding that is the entire deduction stack on a Mississippi stub. There is no third line, which is exactly the point of the next section.

What Mississippi Does Differently

Mississippi's income tax is a flat 4% on everything above a $10,000 zero band, so at $85,000 it takes $2,668.00 — just 3.14% of gross. The rate has fallen every year since 2023 under the HB 531 phase-down, and HB 1 keeps cutting: 3.75% in 2027, toward 3% by 2030. The trade-off is the 7% sales tax, one of the highest base rates in the country, and Social Security and retirement income are fully exempt from the state tax.

Overtime and Pay-Frequency Math

Mississippi follows the federal Fair Labor Standards Act: non-exempt employees earn 1.5x their regular rate for hours over 40 in a week, with no stricter state daily-overtime rule on top. At $30/hour and a 45-hour week: 40 x $30 = $1,200 straight time, 5 x $45 = $225 overtime, $1,425 gross for the week. Salaried exempt employees are outside this rule under the duties-and-salary-basis test, so a $85,000 salary means $85,000 of gross regardless of hours.

Pay frequency then decides the per-check number without changing the annual total. On $85,000: weekly (52) = $1,634.62; biweekly (26) = $3,269.23; semi-monthly (24) = $3,541.67; monthly (12) = $7,083.33. The existing $85,000 example uses biweekly, the most common Mississippi schedule. Note that overtime and bonuses can push individual checks into higher withholding on that check alone; withholding per check annualizes the amount, so a spike check withholds as though you earned at that pace all year, with the balance settling at filing time.

New to Mississippi Paychecks: Reading Your First Stub

A first Mississippi pay stub surprises newcomers in two ways: there is no state line at all, and the federal and FICA lines look larger than expected because nothing else shares the load. Read it top to bottom. Gross is what you earned. Pre-tax items come off next. FITW (federal income tax withheld) follows your W-4. Then the two FICA lines. The remainder is net. The year-to-date column repeats the same stack cumulatively, which is how you spot a drift early — if YTD federal withholding looks high relative to gross in March, file a new W-4 rather than waiting until filing season. Anyone arriving mid-year should set the W-4 for the new situation on day one: settings calibrated to a previous state system will systematically over- or under-withhold here. Our US paycheck calculator lets you model the stub before the first one prints.

Tipped, Hourly, and Third-Paycheck Months

Mississippi hospitality runs on tipped wages, and the federal rules are specific. Employers may pay a cash wage as low as $2.13 per hour provided tips bring total hourly earnings to at least the $7.25 federal minimum; if they do not, the employer makes up the difference. Overtime for tipped and hourly staff alike is 1.5 times the regular rate past 40 hours a week. Separately, biweekly earners get two third-paycheck months every year: 26 paychecks cannot divide evenly into 12 months, so two months contain three paydays. The annual total is unchanged, but budgeting monthly on two checks and treating the third as surplus is the standard move. Monthly billers should note the mirror image: semi-monthly schedules never produce a third check, so compare offers on annual gross, not per-check size.

Self-Employed in Mississippi: What Changes

Without an employer there is no withholding at all, so the full stack lands on you four times a year. Self-employment tax replaces both halves of FICA: 12.4% for Social Security up to the annual wage base plus 2.9% for Medicare, with the additional 0.9% over the statutory thresholds exactly as for employees — 15.3% combined before income tax. Half of that combined amount is deductible when computing income tax, which softens it but does not remove it. Federal estimated payments fall on the fixed calendar: January 15, April 15, June 15 and September 15, shifting to the next business day when the date lands on a weekend. Mississippi adds nothing on top: no state estimates, no state return, no state-level equivalent to argue about. Miss a federal quarter and interest accrues from the due date, so new freelancers should set calendar reminders before the first April deadline surprises them. Keep 25 to 30 percent of each client payment in a separate account and the quarters stop hurting.

Bonuses, Commissions, and Supplemental Pay

Not everything on a Mississippi stub follows the salary rules. Bonuses, commissions, severance, and back pay are supplemental wages, and employers may withhold federal tax on them at a flat 22% up to $1 million in a year (37% above that), instead of running them through the W-4 percentage method. That is why a $5,000 bonus can arrive as $3,900 before FICA even though your salary withholding implies a lower rate: $5,000 x 0.22 = $1,100 held back, plus 6.2% Social Security and 1.45% Medicare on top. Mississippi adds nothing either way, so a Mississippi bonus beats the same bonus in California by the state slice alone. The flat rate is only withholding, not the final tax — the actual liability settles at filing time against your real marginal rate, which is why bonus-heavy earners in Mississippi often see meaningful refunds. Overtime already covered above counts as regular wages, not supplemental pay, so the two rules never stack on the same dollar.

The Honest Footnote: Total Burden Matters

Mississippi's state income tax is one of the lightest in the country at $85,000, but total burden is more than the state tax line. The 7% sales tax is among the highest base rates anywhere, with only Jackson (8% combined) and Tupelo (7.25%) adding anything on top, and groceries are taxed at a reduced 5% since July 2025. There is no local income tax, no state disability or paid-leave deduction, and retirement income is exempt. Federal tax, Social Security and Medicare are the same everywhere; it is the state slice that varies.

Living on a Mississippi Paycheck: What Makes Mississippi Different

Mississippi's income tax is a single flat rate with a zero band: the first $10,000 of taxable income is taxed at 0% and everything above it at 4% for 2026. The 4% rate is the final step of House Bill 531's phase-down — 5% in 2023, 4.7% in 2024, 4.4% in 2025 — and House Bill 1, signed March 27, 2025, keeps the cuts going at 3.75% in 2027 and toward 3% by 2030 if revenue triggers are met.

Before the zero band, two deductions come off: a $6,000 personal exemption and a $2,300 standard deduction for single filers, $8,300 combined — and that $8,300 is the combined figure, not a separate deduction on top of the exemption. Mississippi computes taxable income independently from the federal return, so the federal standard deduction plays no role here. On an $85,000 salary the Mississippi taxable income is $76,700, and 4% of the $66,700 above the zero band is $2,668.00.

Mississippi is unusually generous to retirees: Social Security benefits and qualified retirement income are fully exempt from state income tax under Miss. Code §27-7-15, so a retiree's pension and Social Security never enter the 4% calculation at all. There is no city, county or school-district income tax in Mississippi, and no employee-paid state disability or paid-leave program, so beyond federal tax and FICA the only Mississippi line on a typical stub is the 4% income tax.

Mississippi's retirement exemption is broad: it covers Social Security and qualified retirement income — pensions, 401(k)s and IRAs — under Miss. Code §27-7-15, so a retiree living on those sources can owe no Mississippi income tax at all. That is the mirror image of Montana, which taxes Social Security to the extent it appears in federal income, and it is one reason Mississippi's effective burden for retirees is among the lowest in the country.

Mississippi has no state minimum wage of its own, so the federal $7.25 an hour applies — the lowest floor in the country alongside the handful of other states that never set a higher rate. There is no state overtime statute either, so the federal Fair Labor Standards Act sets the rule: time and a half past 40 hours a week.

The trade-off for the low income tax is at the till: Mississippi's 7% state sales tax is one of the highest base rates in the country, with almost no local add-ons — only Jackson adds 1% (8% combined) and Tupelo 0.25% (7.25%). Groceries eligible for SNAP purchase are taxed at a reduced 5% since July 1, 2025, down from 7%.

The 7% sales tax reaches most goods and many services, and Mississippi is one of the few states that still taxes groceries at close to the full rate — the reduced 5% rate for SNAP-eligible groceries, in force since July 1, 2025, is the first break shoppers have had. Only two cities add their own layer: Jackson's 1% infrastructure tax takes the combined rate to 8%, and Tupelo's 0.25% takes it to 7.25%. Everywhere else in the state, the rate on the receipt is simply 7%.

Filing uses Form 80-105 for residents (Form 80-205 for non-residents and part-year residents), due April 15, with an automatic extension to October 15 when you hold a federal extension — but any tax owed must still be paid by April 15, using Form 80-106, to avoid penalty and interest. Returns are filed through the Department of Revenue's Taxpayer Access Point portal. On the $85,000 example the Mississippi slice is $2,668, leaving $65,959.50 a year — about $2,537 every two weeks — the highest take-home of the three states in this batch, because the flat 4% costs less than Maine's or Montana's brackets at this salary.
