A single filer earning Mississippi's median household income of $55,980 owes about $1,507 in Mississippi state income tax — an effective state rate of 2.69%. That is state tax only, on top of federal income tax and FICA.

Based on 2026 Mississippi rules and 2026 federal rules, with the standard deduction and no other adjustments. Median income is the 2024 Census figure.

Income tax in Mississippi

For 2026, Mississippi exempts the first $10,000 of taxable income and taxes the rest at a flat 4.0%, down from 4.4% in 2025. The Build Up Mississippi Act continues the phase-down — 3.75% is already scheduled for 2027, then annual cuts toward 3.0% by 2030, with a legislated path toward eliminating the income tax entirely.

Mississippi income tax structure (2026)

Mississippi uses 2 progressive brackets on income above a $2,300 standard deduction (single) plus a $6,000 personal exemption. Single-filer brackets:

$0 – $10,0000%
over $10,0014%

Married-filing-jointly thresholds differ (roughly double in most states). Each slice of income is taxed at its own rate — landing in a bracket does not tax your whole income at that rate.

Common questions

What are Mississippi's income tax brackets?
Mississippi does not really use brackets for 2026: the first $10,000 of taxable income is untaxed, and everything above it is taxed at 4%. Taxable income here is your pay after a $2,300 standard deduction ($4,600 joint) and a $6,000 personal exemption per filer. The same thresholds apply to joint filers, though the standard deduction doubles.
What is the top income tax rate in Mississippi?
4%, and it begins at $10,000 of taxable income for a single filer — about $18,300 of gross pay, once the $8,300 Mississippi subtracts first is added back. Only income above that point is taxed at that rate; everything below it is exempt.
What is the tax bill on $55,980 in Mississippi?
A single filer on Mississippi's $55,980 median household income (2024 Census figure) owes roughly $1,507 to Mississippi — an effective state rate of 2.7% against a 4% marginal bracket — plus about $4,538 of federal income tax.
Does Mississippi have a personal exemption?
Yes — $6,000 per filer, or $12,000 on a joint return, subtracted before the 4% rate applies. It is larger than Mississippi's own standard deduction ($2,300 single), so the exemption does most of the sheltering.

Estimates for general informational purposes only; not tax advice. Mississippi figures are simplified (credits, local taxes, and AGI adjustments vary) and should be verified with the state Department of Revenue. Mississippi's single-rate 4% schedule is applied with the $2,300 standard deduction and $6,000 personal exemption for a single filer — not itemized deductions, exemption phase-outs, or any Mississippi tax credit. It also excludes any local, county, or school-district tax your municipality may add.
