Mississippi Paycheck Tax Calculator: How Mississippi Withholding Works
A Mississippi paycheck calculator has one state
line to get right: the 4% income tax after deductions, exemptions
and the $10,000 zero band. On your pay stub it usually appears as
SIT or MS state withholding.
Our
pay stub abbreviations list
explains the other codes.
Federal Withholding for Mississippi Paychecks
Federal withholding uses your Form W-4 and the 2026 federal
brackets. The calculator supports filing status, Step 2(c), Step 3
credits and Step 4(a), 4(b) and 4(c). If you claim the new overtime
or tips deductions, our
W-4 Step 4(b) worksheet guide
shows how to enter them, and our
2026 federal tax withholding guide
covers the rest.
Working Across State Lines
Mississippi has no reciprocal agreements. If you live in
Louisiana,
Alabama
or Arkansas and work in Mississippi, your employer withholds
Mississippi tax and your home state gives you a credit. Tennessee
residents working in Mississippi pay Mississippi tax with nothing to
offset it at home.
Bonuses
Mississippi has no flat bonus rate. Your employer adds the bonus to
your regular wages for the pay period and withholds on the total,
which can push that paycheck's withholding up. Federal withholding
(usually a flat 22%) and FICA apply too. See
why bonuses are taxed so high.
Employer Payroll Costs in Mississippi
Employers pay state unemployment insurance
on the first $14,000 of each employee's wages. None of it comes out
of your pay. At year-end, our
W-2 form generator
can use the same wage and withholding totals.
Why Your Actual Mississippi Paycheck May Differ
This calculator is a close estimate, not your employer's payroll
run. Your Form 89-350 on file, whole-dollar rounding, how you and
your spouse split the married exemption, benefit elections,
year-to-date wages and a 27th biweekly payday in some years can all
move the result a little.
Three-paycheck months
change monthly cash flow but not the tax on each check. For a full
checklist, see why your paycheck is lower than expected.
