Mississippi Paycheck Calculator: Calculate Your 2026 Take-Home Pay

Our Mississippi Paycheck Calculator helps you estimate your net (take-home) pay after federal taxes, FICA (Social Security and Medicare), Mississippi state income tax, and pre-tax deductions. Mississippi taxes income at a flat 4% rate for 2026 (down from 4.4% in 2025) but exempts the first $10,000 of taxable income. This tool provides a detailed breakdown of your earnings and deductions for the 2026 tax year. Use our Take Home Paycheck Calculator for a general estimate and the Income Tax Calculator to analyze your federal tax liability.

How Mississippi State Income Tax Works

Mississippi is phasing down its income tax rate as part of a multi-year reform plan (HB 1733). The rate schedule is: 5% in 2023, 4.7% in 2024, 4.4% in 2025, 4% in 2026, with further reductions to 3.75% in 2027, 3.5% in 2028, 3.25% in 2029, and 3% in 2030. The first $10,000 of Mississippi taxable income is fully exempt. Mississippi allows its own standard deduction and personal exemption separate from federal amounts.

Key features of Mississippi state income tax:

• Flat 4% rate on taxable income above $10,000 for 2026
• First $10,000 of taxable income exempt (0% rate)
• Standard deduction: $2,300 single / $4,600 married / $3,400 head of household
• Personal exemption: $6,000 single / $12,000 married / $8,000 head of household
• $1,500 additional exemption per dependent
• No local income taxes
• All retirement income (Social Security, pensions, 401(k), IRA) fully exempt

Federal Tax and FICA Deductions

This calculator applies the 2026 federal income tax brackets based on your filing status. The standard deduction for 2026 is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household. FICA taxes include Social Security at 6.2% (up to the annual wage base of $184,500), Medicare at 1.45%, and Additional Medicare at 0.9% for high earners above $200,000 ($250,000 for joint filers).

How This Is Calculated

This calculator is based on 2026 IRS federal tax brackets and FICA, plus each state's latest published income-tax schedule. Mississippi's tax is calculated on your income after subtracting the Mississippi standard deduction, personal exemption, and dependent exemptions. The first $10,000 of the resulting amount is exempt, and the remainder is taxed at 4%. Pre-tax deductions (401(k), HSA, health premiums) reduce your taxable income before all taxes are applied.
