Mississippi Payroll Compliance Guide 2026: Complete Employer Reference

Mississippi Payroll Overview

Mississippi is one of the more straightforward states for payroll compliance. The 2024 income tax reform simplified a graduated system into a single flat rate, making withholding calculations easier. There is no state minimum wage, no state paid family leave, and no complex local tax overlay. Your primary state obligations are income tax withholding and SUI.

One thing to stay on top of: the income tax rate is scheduled to decline every few years. The rate in effect when you set up your payroll system today won’t be the same rate in 2027. Mississippi’s Department of Revenue will publish updated withholding tables when each rate change takes effect. Update your payroll system at that time.

Mississippi requires workers’ compensation coverage for most employers. The Mississippi Workers’ Compensation Commission oversees the program. Unlike some states, Mississippi does not have an optional out for private employers—coverage is mandatory once you have five or more employees (certain agricultural and domestic workers are exempt).

Mississippi Payroll Taxes: 2026 Rates and Wage Bases

Mississippi Income Tax Withholding: The 2024 Reform

Mississippi’s 2024 tax reform legislation (House Bill 1) replaced the prior graduated income tax structure with a flat rate. The old system had three brackets; the new structure applies a single rate to all taxable income. The reform also eliminated the state income tax on the first $10,000 of income—meaning many lower-wage workers owe little to no state income tax on their wages.

The Declining Rate Schedule

Future rate reductions are tied to revenue performance. If state revenues hit defined benchmarks, the rate drops on schedule. If revenues fall short, the schedule could slow. The Mississippi Department of Revenue will announce changes when they take effect. As of April 2026, the applicable withholding rate is 4.7%.

Mississippi Withholding Form and Account Setup

Mississippi employees complete a state withholding exemption form. Employers use this form plus the MDOR withholding tables to calculate per-period withholding. With a flat rate, the calculation is simpler than graduated systems: taxable wages (after exemptions) multiplied by 4.7%.

Register for a Mississippi Withholding Account at dor.ms.gov. File withholding returns and make deposits through the Taxpayer Access Point (TAP) portal. Annual W-2 reconciliation is due January 31.

Withholding Deposit Frequency

MDOR assigns a deposit frequency based on your annual Mississippi withholding liability. Employers with smaller withholding amounts typically file quarterly; larger employers file monthly. Semi-monthly filing applies at the highest withholding levels. Your assigned frequency appears in your MDOR account.

Mississippi SUI: Unemployment Insurance

Mississippi SUI is administered by the Mississippi Department of Employment Security (MDES). The taxable wage base is $14,000 per employee per year.

New Employer Rate

New employers pay SUI at 1.0% on the first $14,000 per employee, capping the new-employer per-employee cost at $140 per year. That’s one of the lowest absolute new-employer SUI costs in this guide. The experienced-employer range is 0.2% to 5.4%. Even at the 5.4% maximum, the annual per-employee cap is $756—modest compared to states with higher wage bases.

Experience Rating

After accumulating three years of claim history, MDES assigns an experience-based rate. Your rate depends on your reserve ratio—cumulative SUI taxes paid minus claims charged, relative to your average annual taxable payroll. Higher reserves mean lower rates. MDES sends annual rate notices. The online employer portal at www.mdes.ms.gov shows your current account balance and rate.

Quarterly SUI Filing

File quarterly SUI returns through the MDES employer portal. Report per-employee wages and total taxable wages each quarter. Quarterly deadlines: April 30, July 31, October 31, January 31. MDES imposes a 10% penalty on delinquent reports, plus interest on unpaid taxes.

Wage Payment Laws and Final Paychecks

Mississippi wage payment rules come from the Mississippi Code (Title 71, Chapter 1). The Department of Employment Security has some enforcement authority, but employees often pursue wage claims through civil court rather than an administrative agency. Mississippi wage law is less detailed than most states’, which creates both flexibility and ambiguity.

Pay Frequency

Mississippi requires employers to pay wages at least twice per month (semi-monthly). Semi-monthly means two paydays per calendar month—typically the 1st and 15th, or the 15th and last day. You must set regular paydays and maintain them consistently.

Final Paycheck Deadline

Mississippi requires final wages by the next regular payday after separation. This applies to both discharges and voluntary resignations. There is no accelerated deadline for terminations in Mississippi.

Vacation Payout

Mississippi law does not require employers to pay out accrued vacation or PTO at separation. Your written policy governs. Courts will enforce a policy that promises payout, and will also generally uphold a forfeiture clause if clearly communicated before the employee accrued the leave.

Deductions from Wages

Mississippi law is relatively permissive about wage deductions. Deductions required by law (taxes, garnishments) are always allowed. Deductions for employer-benefit purposes must be authorized by the employee in writing. Deductions that reduce wages below minimum wage require care—even in Mississippi, employer deductions that push an employee below FLSA minimum wage violate federal law.

Overtime and FLSA

Mississippi has no state overtime law. Federal FLSA governs all overtime for Mississippi employers: 1.5× the regular rate for hours over 40 in a workweek. No daily overtime requirement exists. The FLSA white-collar exemption applies at the $684/week salary threshold.

Mississippi’s significant agricultural sector means some employers deal with FLSA agricultural exemptions. Farm workers have different FLSA overtime rules (many are exempt from overtime entirely), and seasonal agricultural exemptions apply in certain circumstances. If you employ farm labor, review the FLSA’s specific agricultural provisions.

Mississippi Minimum Wage 2026

Mississippi has no state minimum wage law. The federal minimum wage of $7.25 per hour applies to all employers covered by FLSA. Mississippi is one of five states with no state minimum wage—along with Louisiana, Alabama, Tennessee, and South Carolina. The legislature has not enacted a state minimum in recent sessions, and no ballot initiative process exists in Mississippi to bypass the legislature.

Federal Tip Credit Applies

The federal tip credit applies in Mississippi. Tipped employees can be paid as little as $2.13 per hour in direct wages, provided tips bring their total to at least $7.25. If tips fall short in any workweek, the employer must make up the difference that week. Employers must inform employees before using the tip credit.

No Local Minimum Wage Authority

Mississippi has no local minimum wage ordinances, and state law does not affirmatively grant or preempt local authority. In practice, no Mississippi city or county has enacted a local minimum wage above the federal floor.
