Mississippi Paycheck Calculator

Mississippi's income tax is about as simple as a progressive-sounding structure can get: 0% on the first $10,000 of taxable income, and a flat 4% on every dollar above that, confirmed directly from the Mississippi Department of Revenue's own individual tax-rates page. There's no third bracket, no escalating rate as income climbs further — once a filer's taxable income clears $10,000, every additional dollar is taxed at the identical 4% rate.

This structure means Mississippi behaves functionally like a flat-tax state (similar to Idaho or Iowa elsewhere on this site) for the vast majority of a typical filer's income, with the 0% zero-bracket acting as a small built-in exemption on the first slice of income rather than a genuinely graduated multi-rate system.

Mississippi is partway through a legislatively fixed, multi-year reduction schedule confirmed directly by the Department of Revenue: 4.4% for tax year 2025, today's 4% for 2026, and an already-scheduled drop to 3.75% for tax year 2027. This calculator applies the confirmed current 4% figure specifically for tax year 2026.

Unlike several other states on this site that conform their standard deduction directly to the federal figure ($16,100 single/$32,200 married for 2026), Mississippi maintains its own, notably smaller state-specific standard deduction: $2,300 for single filers and $4,600 for married filing jointly, confirmed directly by the Mississippi Department of Revenue.

The practical effect is that Mississippi's tax base — the amount of income actually subject to the state's rate — starts from a higher figure relative to gross income than it would in a federal-conformity state, even though Mississippi's headline flat rate (4%) is itself comparatively low. A filer moving from a federal-conformity state to Mississippi at the same salary would see their state taxable income increase due to this smaller deduction, though the lower flat rate largely offsets that difference in practice.

This calculator applies the confirmed $2,300/$4,600 figures directly, sourced from Mississippi's own Department of Revenue rather than a third-party aggregator, given the genuine variation seen across secondary sources when researching this state's exact current-year figures.

This calculator's Mississippi figures cover federal income tax, Mississippi's near-flat state income tax, and the two federal FICA taxes — the complete set of withholding categories that apply broadly to Mississippi wage earners. Mississippi has no state-run disability insurance or paid-family-leave payroll premium as of 2026, unlike states such as Colorado, Rhode Island, or Maine that layer a genuine second payroll deduction on top of income tax.

Mississippi does not levy local city or county income taxes on top of the state rate, so this calculator's stateTax figure represents a complete state-and-local income tax picture for a Mississippi wage earner, similar to the simpler single-layer structure seen in states like Louisiana or Kentucky rather than the local-tax complexity of a state like Maryland or Indiana.

A worker comparing a Mississippi paycheck to a state with local income taxes should keep in mind that Mississippi's structure means this calculator's total figure is closer to a genuinely complete picture than it would be for a state where local add-ons vary by city or county.
