How Income Tax Works in Mississippi (2026)
Mississippi levies a flat 4.0% state income tax in 2026 — the same rate for every dollar of taxable income. On top of federal tax, a single filer earning $75,000 pays about $3,000 in Mississippi state income tax, bringing the combined federal + state income tax bill to roughly $10,670. That's an effective income tax rate of about 14.2%.
A flat tax has a clear advantage for budgeting: a raise never pushes any of your income into a higher state bracket. Every extra dollar earned in Mississippi is taxed at the same 4.0% at the state level. The 4.0% rate is below the 4.8% average among states that tax income.

Methodology & sources
Federal tax uses 2026 IRS brackets and standard deductions (Revenue Procedure 2025-32). State tax rates reflect 2026 law from the Tax Foundation and state revenue departments; graduated-state figures are estimated effective rates. FICA uses the 2026 Social Security wage base of $184,500 (6.2%) plus Medicare (1.45%). Local city or county taxes (e.g. NYC, Portland) are not included. Estimates for planning only, not tax advice.
