Mississippi Paycheck Calculator 2026

Mississippi Payroll Tax Overview

Mississippi uses a flat state income tax rate of 4.4% on all taxable wages. Unlike graduated-bracket states, every dollar you earn in Mississippi above the standard deduction is taxed at the same 4.4% rate. This makes Mississippi paycheck calculations straightforward and predictable.

On top of state income tax, workers in Mississippi also pay federal income tax (10%–37% graduated brackets), Social Security (6.2% up to the $176,100 wage base), and Medicare (1.45%, or 2.35% above $200,000 for high earners). Pre-tax deductions like 401(k) and health insurance reduce both federal and state taxable income.

The 2026 federal income tax brackets for single filers: 10% on the first $11,925; 12% to $48,475; 22% to $103,350; 24% to $197,300; 32% to $250,525; 35% to $626,350; 37% above. Your effective federal rate will be well below the marginal rate at most income levels.

Federal vs Mississippi Tax Burden

For a Mississippi single filer earning $60,000 annually, estimated federal income tax is roughly $6,748 (11.2% effective), plus Mississippi state tax of $1,850 (flat 4.4%), Social Security $3,720, and Medicare $870. Estimated annual take-home: approximately $46,800.

The flat tax structure means Mississippi does not penalize additional income with a higher marginal state rate — every extra dollar earned is taxed at exactly 4.4% for state purposes. This can make Mississippi attractive for higher earners who benefit from the predictability of a flat system.

Pre-tax 401(k) contributions, HSA contributions, and health insurance premiums reduce both federal and Mississippi taxable income before tax is applied. Maximizing pre-tax deductions is one of the most effective ways to reduce your Mississippi paycheck tax burden.

How to Use This Mississippi Paycheck Calculator

Enter your pay period (weekly, biweekly, semimonthly, monthly, or annual), then input either your annual gross salary or your hourly rate and average hours per week. Select your federal filing status — single, married filing jointly, married filing separately, or head of household — as this determines your federal tax brackets and standard deduction.

If you have pre-tax deductions such as a 401(k) contribution, health insurance premium, or HSA contribution, enter the total per-period dollar amount. These reduce your taxable income before federal and state taxes are calculated. The calculator will show federal income tax, Social Security (6.2%), Medicare (1.45%), Mississippi state income tax (4.4%), your total deductions, and your net take-home pay — both per period and annualized.

Results are estimates based on standard assumptions and 2026 tax rates. Actual withholding may differ based on your W-4 elections, additional withholding, local taxes (in some cities), or retirement plan contribution limits. For precise payroll calculations, consult your payroll provider or a tax professional.

Mississippi Flat-Tax Phase-Down Schedule and 2026 Rate

Mississippi is in the middle of a multi-year flat-tax phase-down enacted by HB 531 ("Mississippi Tax Freedom Act"). Per the Mississippi Department of Revenue official rate schedule, the flat rate stepped down from 5.0% to 4.7% in 2024 and to 4.4% in 2026. The plan continues: 4.0% in 2027, and the final phase reduces it toward 3.0% by 2030 (subject to legislative funding triggers). The state's first $10,000 of taxable income is excluded entirely — so a single filer with $50,000 taxable income pays 4.4% only on $40,000 ($1,760 in state tax), not the full $50,000. This calculator applies the flat 4.4% rate above the exemption, the standard treatment used by most Mississippi paycheck calculators. Note: Mississippi has no local/county income tax, unlike Maryland or Pennsylvania — your paycheck deductions stop at the state line. Updated 2026-06-24.
