If you run a business in Mississippi with employees, you owe state unemployment tax to the Mississippi Department of Employment Security (MDES). The Mississippi unemployment tax is a quarterly, employer-only contribution on the first $14,000 of each worker’s annual wages. Rates range from 0.20% to 5.40% once your account has a claims history; new employers start at a flat 1.0% and work up to 1.2% over their first three years. Most employers also pay a 0.20% training contribution on top of that.
Which Employers Have to Pay
You become liable the moment you cross one of two thresholds. The first: you paid at least $1,500 in wages during any calendar quarter in the current or preceding year. The second: you had at least one worker on the payroll for any part of a day in 20 different calendar weeks within a year, even if those weeks weren’t consecutive and the workers changed.1FindLaw. Mississippi Code 71-5-11 – Definitions Meeting either one is enough.
Farms and agricultural operations have higher thresholds. An agricultural employer becomes liable at $20,000 or more in cash wages during any calendar quarter, or when it has employed ten or more workers for part of a day in 20 different weeks.1FindLaw. Mississippi Code 71-5-11 – Definitions
Religious, charitable, and educational organizations follow a different rule: a nonprofit is subject to the tax if it employed four or more people for part of a day in 20 different weeks within the current or preceding calendar year.1FindLaw. Mississippi Code 71-5-11 – Definitions Once you cross your threshold, you register with MDES and begin paying.
How Much You Pay
The tax applies only to the first $14,000 of wages paid to each employee per calendar year. Earnings above that for the same worker aren’t taxed again until the following year. Employers cannot deduct any part of this tax from a worker’s paycheck.2Mississippi Department of Employment Security. Mississippi Employment Security Law
New Employer Rates
A newly liable employer pays 1.0% of taxable wages in the first year, 1.1% in the second, and 1.2% in the third and later years until the business qualifies for an experience-based rate.3Justia Law. Mississippi Code 71-5-353 – Rate of Contributions To qualify for experience rating, your account must have been chargeable for at least twelve consecutive months.
Experience-Rated Employers
After enough history, your rate shifts to reflect what your account has actually cost the fund. Employers with few or no claims earn lower rates; employers with frequent layoffs pay more. The range runs from 0.20% to 5.40%, and the combined general experience rate and individual experience rate can never exceed 5.40%.4Mississippi Department of Employment Security.

Training Contribution
Most employers pay an additional 0.20% of taxable wages toward workforce training programs. Government entities, institutions of higher learning, and nonprofits that reimburse the fund directly are exempt from the training contribution.3Justia Law. Mississippi Code 71-5-353 – Rate of Contributions
The Nonprofit Option: Reimburse Instead of Contribute
Eligible 501(c)(3) nonprofits have a choice most private employers don’t. Instead of paying the standard quarterly rate, a nonprofit can elect to reimburse the state dollar-for-dollar for benefits actually paid to its former employees. It pays nothing when no one files a claim, and reimburses the full amount of regular benefits plus half of any extended benefits attributable to its workforce.6Justia Law. Mississippi Code 71-5-357 – Reimbursement in Lieu of Contributions
For a nonprofit with stable staffing, this can cost less than paying a percentage of wages every quarter. The flip side: one large layoff produces a direct, potentially substantial bill. The election is made through MDES procedures, and the organization stays on that method for the effective period.
How to File and Pay Each Quarter
Two forms make up the core filing. Form UI-3, the Employer’s Quarterly Wage Report, lists each employee’s name, Social Security number, and total gross wages for the quarter. Form UI-2, the Quarterly Contribution Report, calculates taxable wages and the tax owed.7Mississippi Department of Employment Security. Instructions for Completing Form UI-2/3 Both can be submitted electronically through the MDES portal. Reportable wages include bonuses, commissions, and other taxable compensation, all counting toward the $14,000 cap.
The quarterly deadlines are:
- First quarter (January–March): due April 30
- Second quarter (April–June): due July 31
- Third quarter (July–September): due October 31
- Fourth quarter (October–December): due January 31
When a deadline falls on a weekend, it moves to the next business day.8Mississippi Department of Employment Security. Quarterly Report and Tax Due Dates
If you later discover a wrong Social Security number, misspelled name, or missing or incorrect wage figure, file Form UI-3B, the Employer’s Quarterly Adjustment Report, to fix it. You need a separate UI-3B for each quarter being corrected.9Mississippi Department of Employment Security. Employer’s Quarterly Adjustment Report
What Late Filing Costs
Interest and penalties stack. Unpaid contributions accrue interest at 1% per month (or any partial month) from the due date until the full balance, including accrued interest, is received.10Justia Law. Mississippi Code 71-5-363 – Interest on Past Due Contributions
On top of interest, MDES imposes a 10% penalty on the tax due if the quarterly report is more than 30 days late. A second 10% penalty applies 60 days after the due date or when MDES issues a warrant for collection. Combined penalties generally will not exceed 20% of the tax due for any single quarter.4Mississippi Department of Employment Security. Employer FAQs The executive director has discretion to abate interest in some cases when settling past-due amounts.10Justia Law. Mississippi Code 71-5-363 – Interest on Past Due Contributions
How State Tax Affects Your Federal FUTA Bill
Mississippi unemployment tax sits alongside the federal unemployment tax under FUTA. The statutory FUTA rate is 6.0% on the first $7,000 of each employee’s annual wages.11Office of the Law Revision Counsel. 26 USC 3301 – Rate of Tax Employers who pay their Mississippi contributions on time and in full receive a credit of up to 5.4% against the federal rate, dropping the effective FUTA rate to 0.6%.12U.S. Department of Labor. FUTA Credit Reductions
That credit is why timely state payment matters beyond avoiding state penalties. If Mississippi were ever to carry an outstanding federal loan balance for its unemployment trust fund, the Department of Labor could impose a credit reduction that raises the effective FUTA rate for every employer in the state. Mississippi is not currently subject to a credit reduction.12U.S. Department of Labor. FUTA Credit Reductions Federal unemployment tax is reconciled annually on IRS Form 940.
Two Traps That Create Unexpected Bills
Misclassifying Workers as Contractors
Treating workers as independent contractors when they should be employees is one of the fastest ways to generate a tax problem. MDES investigates questionable employment tax practices, and employers caught misclassifying workers owe the unemployment taxes they should have been paying all along, plus penalties.13Mississippi Department of Employment Security. Questionable Employment Tax Practices The exposure doesn’t stop at the state line: misclassification can also mean unpaid FUTA, IRS penalties, and workers’ compensation and wage-and-hour claims.
The test turns on control. If you set the hours, provide the tools, and direct how the work gets done, that person is almost certainly an employee for unemployment tax purposes regardless of what your contract says.
Buying a Business and Inheriting Its Rate
When you buy a business already registered with MDES, you inherit the seller’s unemployment tax rate. A company acquiring a business with a high claims history takes on that elevated rate rather than starting at the new-employer rate. If only part of a business changes hands, MDES evaluates the situation individually and may assign a new employer rate or one based on the employment and claims history of the portion acquired.14Mississippi Department of Employment Security. Employer Reference Guide Any change in business status or ownership must be reported to MDES using the Employer Change Request form.15Mississippi Department of Employment Security. Downloadable Forms Before closing on an acquisition, check the target’s current rate. A rate near 5.40% carries meaningfully higher payroll costs than the 1.0% a fresh business would start with.
