How Mississippi state tax withholding works
Mississippi taxes wage income, so your employer withholds Mississippi income tax from each paycheck in addition to federal tax. You tell your employer how much to withhold on Form 89-350 (Mississippi Employee's Withholding Exemption Certificate), the state’s counterpart to the federal Form W-4.
For 2026, Mississippi applies a flat 4% rate to your taxable wages, after a standard deduction of $2,300 (single) or $4,600 (married filing jointly) and personal/dependent exemptions.

Mississippi vs. federal withholding
Your Mississippi and federal withholding are figured separately. Federal withholding follows the IRS Publication 15-T tables and your Form W-4; Mississippi withholding follows the state’s own rates and your Form 89-350. Getting one right doesn’t guarantee the other — this calculator handles both so you don’t owe a surprise bill to either the IRS or Mississippi.
Important Mississippi notes
- Mississippi applies a flat 4.0% rate on taxable income (first ~$10,000 is exempt via exemptions).
