How is income tax calculated in Mississippi?

Federal tax uses the same brackets in every state; Mississippi applies its own state tax on top, using its own brackets (or a flat rate, or no state income tax at all). This calculator adds FICA payroll taxes — Social Security and Medicare — to estimate your real take-home pay.

Does this account for deductions and credits?

This is an estimate using standard brackets and the standard deduction — it doesn't model itemized deductions, additional credits, or adjustments specific to your situation.

How often do these rates change?

Tax brackets are typically indexed to inflation each January. We update this calculator annually with newly published rates.

Does Mississippi's tax rate apply to all my income, or just income earned there?

For most employees, Mississippi's state tax applies to income earned while resident and working there. If you moved partway through the year, or you live in one state and work in another, part-year rules and reciprocity agreements mean your actual return may differ from this single-state estimate.

Why does my take-home pay differ from what my employer withholds?

Payroll withholding uses simplified per-paycheck formulas driven by your Form W-4, and may not match your exact annual tax liability. This calculator estimates your full-year tax based on annual income; use it alongside your pay stubs rather than as a replacement for them.

The math: federal plus state brackets

Income tax is calculated using marginal tax brackets — each portion of income is taxed at its own bracket's rate, not the top rate applied to the whole amount. Federal tax and Mississippi's state tax are calculated separately using their own bracket tables, then added together. FICA — 6.2% Social Security up to the annual wage base, plus 1.45% Medicare on every dollar — is calculated on top of income tax to find your take-home pay.
