Employer of record in Mississippi: PEO rules, payroll registration and what the client still owns (2026)

As of October 2026, Mississippi does not license or register professional employer organizations (PEOs) or employer of record (EOR) providers. Any firm that supplies workers to another business is still a "third-party employer" under the Mississippi Employment Protection Act. It must register with the Mississippi Department of Employment Security (MDES) before placing anyone and show each client proof of that registration and of its E-Verify use. For unemployment insurance, Mississippi makes the client the employer of workers supplied by an "employee leasing firm" and makes a temporary help firm the employer of its temps, so the label that fits your provider decides whose MDES account carries the wages.

This page is for a company outside Mississippi, or a staffing firm, deciding whether to employ a Mississippi worker through an EOR or PEO or to register itself. The general difference between an EOR, a PEO and payrolling is in what is an employer of record and payrolling services explained; the full state checklist is in hiring employees in Mississippi, and agency rules are in staffing agency license in Mississippi.

Mississippi employer of record and PEO rules at a glance

Does Mississippi license PEOs or employer of record companies?

No. Mississippi has never enacted a PEO licensing or registration act. A 1998 bill died in committee, and House Bill 331 (2021) and House Bill 1520 (2022), which would have required registration with the Mississippi Insurance Department, passed the House and died in Senate committee. We found no PEO or employee leasing bill in the Legislature's lists of 2023, 2024, 2025 or 2026 measures. There is therefore no license fee, bond, net worth test or public list of approved providers to check, and the phrase "employer of record" does not appear in the statutes discussed here.

What does reach every EOR and PEO is the Mississippi Employment Protection Act. Miss. Code § 71-11-3(3)(c), as reprinted in House Bill 899 (2026), defines a "third-party employer" as "any person or company that provides workers for another person or company," including "leasing companies and contract employers." Under § 71-11-3(6), all third-party employers doing business in Mississippi "shall register to do business in Mississippi with the Mississippi Department of Employment Security before placing employees into the workforce in Mississippi," and must provide "proof of registration and any participation in the status verification system" (E-Verify) to every Mississippi employer they do business with. That proof is the closest thing Mississippi has to a license check: ask for it before the worker starts.

Who pays Mississippi unemployment tax on an EOR or PEO worker?

The Employment Security Law sorts providers into two groups. As reprinted in House Bill 876 (2022), Miss. Code § 71-5-11 defines an "employee leasing firm" as an entity that handles "payment of wages, reporting of wages for unemployment insurance purposes, payment of unemployment insurance contributions and other administrative duties" for a client's employees "that are directed and controlled by the client and that are providing ongoing services for the client." A "temporary help firm" hires its own employees and supplies them to support or supplement a client's workforce in special situations such as absences, skill shortages, seasonal workloads and projects.

Section 71-5-11(H)(10) then assigns the employer role: "All entities utilizing the services of any employee leasing firm shall be considered the employer of the individuals leased from the employee leasing firm," while "Temporary help firms shall be considered the employer of the individuals they provide." For an out-of-state company this is the point that matters most. A long-term EOR arrangement for a remote employee whom the client chose and directs fits the leasing definition more closely than the temporary help one, which would make the client the employer for Mississippi unemployment purposes, with an account in its own name once it crosses the liability threshold of $1,500 in a quarter or 20 weeks of work. The provider can file and pay, but the account and the experience rate are the client's. Get MDES's view in writing before the first payroll.

Who carries workers' compensation in Mississippi?

The Workers' Compensation Commission's answer to who must carry coverage is "any employer with 5 or more employees," with exceptions in Miss. Code § 71-3-5. Because Mississippi has no PEO statute, nothing in state law allocates the policy between a PEO and its client the way the PEO laws of Nebraska or Rhode Island do; the contract decides, and the risk of a gap falls on whichever party a court later treats as the employer. Under the Commission's Rule 1.3, a carrier files proof of coverage through the National Council on Compensation Insurance's Proof of Coverage system, and Rule 1.8 requires a "Notice of Coverage" naming the carrier to be posted at the place of business. Ask for a certificate that names the Mississippi worker or work location, not just the provider's master policy.

Which Mississippi registrations, reports and notices still apply?

• Withholding. The Department of Revenue's Pub. 89-700 requires every employer subject to Mississippi withholding to obtain a withholding account number and to collect Form 89-350 from each new employee; a federal W-4 does not substitute. Confirm the provider's account is open before the first payday.
• New-hire reporting. Within 15 days to the State Directory of New Hires, per MDHS's guide for employers. Agree in writing which company files it.
• E-Verify. MDES says the Employment Protection Act "requires employers to participate" in E-Verify. See E-Verify requirements in Mississippi.
• Posters. MDES says the only state-required posters are the unemployment insurance and workers' compensation posters. A remote worker has no worksite wall, so ask how the provider delivers them.
• Paid leave programs. We found no Mississippi paid leave or disability insurance program that needs a separate employer registration.

What does the client company still own in Mississippi?

An EOR runs payroll; it does not run the job. The client still chooses the worker, sets the work and supervises it, so these stay with you in practice:

• Hiring decisions. Mississippi has no pay transparency rule, salary history ban or private ban-the-box law, per our Mississippi hiring checklist, but federal discrimination law and the FCRA background check process apply to whoever makes the decision. A remote role advertised to candidates in other states can pick up their rules, such as those in pay transparency laws by state.
• Drug testing. If you test applicants under Mississippi's testing chapter (Miss. Code § 71-7-1 and following), it requires written notice before collection and a confirmed result; see Mississippi drug testing laws and drug testing laws in hiring.
• Interviews. Mississippi is one-party consent for recording; see Mississippi recording consent law for interviews.
• Safety, conduct and complaints. Day-to-day supervision, harassment complaints and workplace safety follow the person who controls the work. With no PEO statute to divide liability, the contract and general law decide, and both companies can be treated as joint employers; see joint employer liability for staffing agencies.
• Federal payroll tax exposure. The IRS says the common-law employer "generally remains responsible" for employment taxes when it outsources payroll, unless the provider is a certified PEO listed in the IRS's CPEO public listings.

When is registering your own company in Mississippi the better route?

Mississippi's setup for a single employee is short: an MDES account once you cross the liability threshold, a Department of Revenue withholding account, Form 89-350, E-Verify, a new-hire report and, at five employees, workers' compensation. Registering yourself tends to make sense when:

• The account would be yours anyway. If MDES treats the provider as an employee leasing firm, you are the unemployment employer regardless, which removes much of the reason to use one.
• You expect several Mississippi hires or a permanent presence, so per-worker fees add up.
• You already run multi-state payroll and E-Verify for other states.

An EOR or temporary help firm fits better for a short project, a single hire you may not keep, or a worker you want on a provider's benefits plan. The payrolling version of that choice, and how it is priced, is in payrolling services explained.

Questions to ask an employer of record or PEO before signing for Mississippi

1. Does MDES treat you as a temporary help firm or an employee leasing firm, and under whose MDES account will this worker's wages be reported?
2. Will you send proof of your MDES registration and E-Verify participation, as § 71-11-3(6) requires, before the start date?
3. Who runs the E-Verify case for this hire, and who keeps the Form I-9?
4. Who carries workers' compensation, under which class code, and will the certificate name our Mississippi worker or location?
5. Is your Department of Revenue withholding account open, and who collects Form 89-350 and files the new-hire report within 15 days?
6. Are you an IRS-certified PEO, and who is liable for federal employment taxes if you fail to pay them?
7. Who answers unemployment claims and wage disputes, and who decides and pays final wages at termination?
8. How do you deliver the state posters and notices to a remote worker?
9. If we later register in Mississippi, can the worker move to our payroll, and is there a fee?
