Mississippi Payroll Requirements: What Employers Need to Know in 2026

Mississippi payroll uses a flat income tax rate of 4.7% in 2026, following the state's move away from a graduated tax structure. The rate is scheduled to phase down further — to 4.4% in 2027 and 4.0% by 2030 — under legislation enacted in recent years. This means employers should expect a lower withholding rate on future-year returns and should update their payroll systems when the annual rate changes take effect. All taxable wages paid to Mississippi residents and non-residents earning Mississippi-source income are subject to withholding at the current flat rate. The Mississippi Department of Revenue administers withholding, and employers file the quarterly 89-105 withholding return.

Mississippi's State Unemployment Insurance taxable wage base is $14,000 per employee in 2026, and new employers pay a rate of 1.0% on that base — a maximum first-year SUI cost of $140 per worker. The Mississippi Department of Employment Security (MDES) administers the program. Quarterly wage and contribution reports are filed through the MDES online portal separately from the income tax withholding return. Mississippi's SUI trust fund solvency can affect the tax table in effect each year, which may push assigned rates higher or lower depending on the fund balance. See how Mississippi SUI rate tables are determined by the state's trust fund solvency and how new employers transition to experience rating.

Mississippi has no state minimum wage law — the federal floor of $7.25 per hour applies to all covered employers. Mississippi does not allow municipalities to set higher local minimums, so $7.25 is the effective floor across the entire state. Mississippi follows federal FLSA rules for tip credits, overtime, and youth training wages. The state has no paid family and medical leave law and no state disability insurance tax in 2026. Workers' compensation is required for employers with five or more employees under Mississippi law — a threshold lower than some other states.

Final paycheck timing in Mississippi requires that a separated employee's wages be paid within two weeks of the next regular payday following the discharge date. This gives employers somewhat more time than states that require immediate or next-payday payment, but there is still a defined outer limit. The rule applies to discharged employees; resigned employees are generally entitled to final wages on the next regular payday. Mississippi does not have a state-level wage continuation penalty for late final pay comparable to Louisiana's 90-day rule, but employees may pursue civil wage claims through the court system. Review Mississippi payday law requirements including pay frequency rules, permitted deductions, and the civil remedy process for unpaid wages.

New hire reporting in Mississippi must be submitted within 15 days of hire to the Mississippi State Directory of New Hires, maintained by the Department of Human Services. Reports can be filed online through the Mississippi New Hire Reporting website and must include the employee's name, address, Social Security number, date of hire, and the employer's name, address, and federal EIN. Mississippi's workers' compensation requirement for employers with five or more employees means that most businesses must also obtain coverage through a licensed carrier or the Mississippi Workers' Compensation Commission's assigned risk pool before bringing on a fifth worker.

For businesses starting Mississippi payroll, the compliance picture is relatively straightforward compared to states with PFML programs or local income taxes. The primary ongoing obligations are the quarterly 89-105 withholding return and the quarterly MDES unemployment report. The phasing income tax rate means payroll software should be configured to apply the updated flat rate each January 1 as the schedule progresses. See the Mississippi new employer registration guide for step-by-step instructions on setting up withholding and SUI accounts before your first payroll run.
