How much do I take home in Mississippi? — short answer first

Mississippi runs a flat 3.5% individual income tax (2026 projected) — the result of HB 531's (2022) aggressive multi-year phase-down from 5% (2022) toward target ~3.0% by 2030. Mississippi has the lowest median household income in the US ($52,985, 2024 ACS), making the rate reductions disproportionately meaningful for the state's predominantly lower-and-middle-income workforce. Standard deduction is small ($2,300 single / $4,600 joint), but the $6,000 personal exemption per filer materially reduces effective rate for lower earners. Mississippi has no local income tax. Property tax is moderate (~0.65% effective).

The Mississippi take-home pay formula

net_pay     = gross − federal_tax − fica − state_tax − local_tax − pre_tax
federal_tax = Σ (federal_bracket × rate) on (gross − std_dev − 401k − hsa)
fica        = MIN(wages, $181K) × 6.2% + wages × 1.45% + add'l Medicare
state_tax    = Σ (bracket_amount × bracket_rate)    // top rate 3.50% in Mississippi
local_tax    = 0    // no local payroll tax in Mississippi

The 2026 take-home calculation for Mississippi stacks four mandatory deductions: federal income tax (7-bracket progressive), FICA (Social Security capped at $181K + uncapped Medicare), Mississippi state income tax (1-bracket progressive, top rate 3.50%). Pre-tax 401(k) and HSA reduce federal taxable income; HSA additionally reduces FICA wages.

How Mississippi taxes payroll in 2026

Mississippi levies a flat 3.5% individual income tax (2026 projected) under §27-7-5 Mississippi Code. The rate is on an aggressive multi-year phase-down under HB 531 (2022): 5% (2022) → 4.7% (2023) → 4.4% (2024) → 4% (2025) → 3.5% projected (2026) → target ~3.0% by 2030. The 2026 rate is conditional on state revenue meeting growth triggers; Mississippi has met its triggers consistently. The 3.5% projection is the most likely outcome. Pre-2022, Mississippi had a 3-bracket progressive structure (3% / 4% / 5%). HB 531 collapsed this into a flat rate. The reform was politically significant — Mississippi was one of the last Deep South states to retain a progressive structure, and the flat-rate adoption aligned the state with neighboring Tennessee (no income tax) and Alabama (effectively flat 5%). Mississippi's standard deduction is among the most restrictive in the US: $2,300 single / $4,600 joint / $3,400 head-of-household (2024 base, minimal indexing). The state offsets this through a generous personal exemption of $6,000 per filer (single) / $12,000 joint — significant relative to the small standard deduction. For most lower-and-middle-income filers, the personal exemption is the more impactful relief mechanism. There is no local income tax anywhere in Mississippi — Jackson, Gulfport-Biloxi, Hattiesburg, Tupelo, and Oxford all fund services through property tax (effective rate ~0.65% statewide — below national average) and 7.07% combined sales tax average (7% state + ~0.07% local, the lowest local-add rate in the US). Mississippi has one of the cleanest state-and-local tax structures in the US — a meaningful contributor to the state's competitive cost-of-living position despite low median wages.

How to use this calculator

Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and Mississippi brackets.
Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.

Common mistakes

Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
Using the wrong filing status for state tax. Mississippi uses the same filing status categories as the IRS, but bracket thresholds differ from federal. Pick the status that matches your actual tax filing — not just what gives the best number.
Ignoring multi-state implications. If you work in Mississippi but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in Mississippi.

Quick reference

Payroll terminology — applies to Mississippi

Gross Salary The headline number from your offer letter, before any deductions. The starting point for every paycheck calculation.: Lenders, landlords, and benefit calculations use gross. Always confirm whether a quoted figure is gross or net — the gap is typically 25-40% in the US once federal + FICA + state are stacked.
Net Take-Home Pay What lands in your bank account after federal + FICA + state + local + pre-tax deductions. The number to budget against.: For Mississippi: gross − federal − FICA − Mississippi state income tax − 401(k) − HSA.
FICA Federal Insurance Contributions Act — payroll tax funding Social Security (6.2% to $181K) + Medicare (1.45%, no cap). 7.65% combined.: Additional Medicare 0.9% applies above $200K single / $250K MFJ. Thresholds frozen since 2013, so an increasing share of earners hit it each year. HSA contributions (but NOT 401k) reduce FICA wages.
Source: SSA — Wage base & tax rates
Marginal Tax Rate The rate applied to your NEXT dollar of income. Drives the cost of a raise, bonus, or extra 401(k) contribution.: In Mississippi, your combined marginal rate stacks federal (12-37%) + FICA (1.45-2.35%) + Mississippi state (3.5%-3.5%). A six-figure earner often faces a 35-45% marginal rate.
Effective Tax Rate Total tax divided by gross income. The actual percentage of your salary that disappears to tax — always lower than marginal.: Two earners at the same gross can have different effective rates depending on pre-tax contributions. Use effective rate for affordability comparisons; use marginal for raise / bonus decisions.
Standard Deduction Fixed amount subtracted from gross before federal brackets apply. 2026: $15,750 single · $31,500 MFJ · $23,625 HoH.: Mississippi's state standard deduction (single) is $2,300 — applied independently before state brackets. Federal and state standard deductions stack; you do not have to itemize on one to claim the other.
Source: IRS Rev. Proc. 2024-40
Pre-Tax Deductions Amounts subtracted from gross BEFORE income tax is computed — 401(k), traditional IRA via payroll, HSA, FSA, employer health premiums.: Reduces federal taxable income dollar-for-dollar. HSA also reduces FICA wages (the 'triple advantage'). Traditional 401(k) reduces federal tax but NOT FICA — Roth 401(k) reduces neither but grows tax-free.
Mississippi State Tax Progressive 1-bracket state income tax. Top rate 3.50%. Filed on Mississippi Department of Revenue.: Brackets refresh annually — most state DORs publish updates in Q4 preceding the tax year. Mississippi's structure is a flat rate, with separate filing-status schedules for MFJ and HoH.
