Mississippi Severance — 4% Flat Rate (HB 531 Glidepath), 2026

Mississippi WARN: what applies#

Mississippi has no state-level mini-WARN notice statute. The operative layoff-notice regime for Mississippi private employers is federal WARN (29 U.S.C. §§ 2101–2109): employers with 100 or more full-time employees must give 60 days advance written notice for a mass layoff (50+ affected at a single site of employment that constitutes at least 33% of the active workforce, or 500+ regardless of percentage) or a plant closing. Notice must go to affected employees (or their representatives), the Mississippi Department of Employment Security Rapid Response unit, and the chief elected official of the local government. Liability for non-compliance is back pay and benefits for each day notice was not given, up to 60 days, plus a civil penalty of up to $500 per day payable to the local government. Mississippi adds no shorter notice, no lower employer-size trigger, and no statutory severance mandate beyond federal WARN.

How severance is taxed in Mississippi#

Mississippi's individual income tax has been on a multi-year glidepath under H.B. 531 of the 2022 Mississippi Legislature (the Mississippi Tax Freedom Act of 2022, signed April 5, 2022): 5.0% (2022 baseline) → 4.7% in 2024 → 4.4% in 2025 → 4.0% in 2026 (the current rate). The Tax Freedom Act eliminated the lower 3% and 4% brackets that existed pre-2022, leaving Mississippi with a SINGLE FLAT RATE structure: a fixed exemption threshold (currently $10,000 single / $20,000 MFJ) below which no Mississippi income tax applies, and the flat 4.0% rate above that threshold for 2026. H.B. 531 also authorized FURTHER rate reductions on a contingent-trigger basis, but the explicit 2026 statutory rate is 4.0%. Because Mississippi uses a flat rate above the exemption, the 4.0% applies uniformly to all wages — Mississippi does not publish a separate supplemental withholding rate distinct from the regular rate. Severance, bonuses, and commissions are withheld at the same 4.0% rate as regular wages under the Mississippi DOR 2026 withholding tables. On top of Mississippi state withholding, severance is subject to the federal 22% supplemental rate (37% on cumulative amounts above $1,000,000 in a calendar year) and FICA (Social Security 6.2% to the wage base, Medicare 1.45% plus 0.9% additional Medicare on wages above $200,000 single / $250,000 MFJ).

FAQ#

Does Mississippi require severance pay?

No Mississippi statute requires private employers to pay severance. Mississippi has no mini-WARN that would mandate pay-in-lieu of notice. The only layoff-notice regime that carries teeth in Mississippi is federal WARN (29 U.S.C. §§ 2101–2109), which requires 60 days advance notice (or back pay for missed days) at employers of 100+ for covered mass layoffs and plant closings — but WARN mandates notice, not severance. Severance is therefore employer-discretionary in Mississippi unless your employment agreement, written severance plan, or company handbook makes it mandatory. Mississippi is a strong at-will employment state.

How is severance taxed in Mississippi?

Mississippi's individual income tax has been on a glidepath under H.B. 531 of 2022 (Mississippi Tax Freedom Act): 5.0% (2022) → 4.7% (2024) → 4.4% (2025) → 4.0% (2026, the current rate). Mississippi now has a SINGLE FLAT RATE structure: a fixed exemption threshold (currently $10,000 single / $20,000 MFJ) below which no Mississippi income tax applies, and the flat 4.0% rate above that threshold. Because Mississippi uses a flat rate above the exemption, the 4.0% applies uniformly to all wages — Mississippi does not publish a separate supplemental withholding rate. Severance, bonuses, and commissions are withheld at the same 4.0% rate as regular wages under the Mississippi DOR 2026 withholding tables. On top of Mississippi state withholding, severance is subject to the federal 22% supplemental rate (37% on cumulative amounts above $1,000,000 in a calendar year) and FICA (Social Security 6.2% to the wage base, Medicare 1.45% plus 0.9% additional Medicare on wages above $200,000 single / $250,000 MFJ). Year-end Mississippi liability is reconciled on Form 80-105.

Does Mississippi have a mini-WARN statute?

No. Mississippi has no state-level mini-WARN that imposes employer notice obligations independent of federal WARN. The operative regime is federal WARN (29 U.S.C. §§ 2101–2109): 60 days advance notice at employers of 100+ for mass layoffs affecting 50+ at a single site that constitute at least 33% of the active workforce (or 500+ regardless of percentage). Notice goes to affected employees, the Mississippi Department of Employment Security (MDES) Rapid Response unit, and the chief elected local official. Federal WARN penalties: back pay and benefits for each day notice was not given (up to 60 days), plus a $500/day civil penalty payable to the local government. Mississippi adds no shorter notice, no lower employer-size trigger, and no statutory severance mandate.

Does OWBPA apply in Mississippi?

Yes. OWBPA is federal (29 U.S.C. § 626(f)) and applies in all states. If you are age 40 or older and your Mississippi employer asks you to sign a waiver of age-discrimination claims under the ADEA in your severance agreement, the waiver is enforceable only if you receive at least 21 days to consider the agreement (45 days for group exits — a 'reduction in force' or 'exit incentive program'), and 7 days after signing to revoke. Group exits additionally require disclosure of the ages and job titles of all selected and non-selected employees in the decisional unit. Mississippi does NOT have a state-level age-discrimination statute paralleling the federal ADEA — Mississippi is one of the very few states without a comprehensive state employment discrimination law for private employers. Federal ADEA, Title VII, and the ADA apply (employers of 20+ for ADEA, 15+ for Title VII and ADA), but smaller Mississippi employers are not covered by state-law discrimination claims. This makes the federal OWBPA review/revocation procedures particularly important for Mississippi severance recipients age 40 or older.

Can I collect Mississippi unemployment while receiving severance?

It depends on how the severance is structured. Mississippi's unemployment disqualification rules are at Miss. Code § 71-5-503 (Disqualifications for benefits) and § 71-5-505 (Continuing eligibility). In practice, the Mississippi Department of Employment Security (MDES) treats severance pay based on allocation: severance designated as 'wages in lieu of notice' or salary continuation tied to a specific notice period typically offsets UI benefits week-by-week during the allocated weeks; a lump-sum severance not designated to specific weeks is more likely to be allocated to the separation date. Practical takeaways: (a) file your MS UI claim with MDES on or shortly after your last day worked at mdes.ms.gov to establish your benefit year; (b) fully disclose the severance amount, structure, and any employer designation when you apply and on weekly certifications — failure to report severance is fraud; (c) Mississippi's maximum weekly UI benefit is $235 (one of the lowest in the country) — verify the live figure at mdes.ms.gov before relying on net-of-benefits estimates.

Are non-competes enforceable in Mississippi after a layoff?

Often yes if reasonable — Mississippi has NO statute governing employer non-competes, and the controlling framework is the common-law 'reasonableness' test adopted by the Mississippi Supreme Court in Empiregas, Inc. v. Bain, 599 So. 2d 971 (Miss. 1992), and applied in subsequent cases. Under this framework, a non-compete is enforceable if it is (1) reasonable in DURATION, (2) reasonable in GEOGRAPHIC scope, (3) reasonable in SCOPE of restricted activities, (4) supported by ADEQUATE CONSIDERATION, (5) ANCILLARY to a legitimate business interest (trade secrets, confidential information, customer relationships, goodwill), and (6) not contrary to public policy. Mississippi courts have judicial blue-pencil authority to strike unreasonable terms — though Mississippi precedent is less developed on whether courts can REFORM (rewrite) overbroad covenants. Continued at-will employment is generally sufficient consideration for a non-compete signed at the start of employment; for mid-employment covenants, separate consideration (raise, promotion, bonus) is the safer practice but not always required. Practical takeaway: in Mississippi, a post-separation non-compete reasonable in time, place, and scope is generally enforceable — so the non-compete release clause in your severance offer has real value. Mississippi's non-compete law is more employer-friendly than California, Oklahoma, or North Dakota (all of which statutorily ban non-competes) but courts have refused to enforce overly broad covenants. Have an attorney review duration, geography, and scope before signing.

Does Mississippi have a state paid family leave program?

No. Mississippi has no statewide mandatory paid family and medical leave program. Mississippi workers rely on federal FMLA (12 weeks unpaid leave at employers of 50+) and any employer-provided STD/LTD or paid leave benefits. Unlike CA, NY, NJ, CT, MA, WA, OR, CO, DE, MD, RI, or DC, Mississippi does NOT deduct paid-leave premiums from your paycheck during active employment, and there is no statewide MS PFL benefit you can stack against severance. Mississippi has one of the most limited state employment-law frameworks for private workers in the country — combined with the absence of mini-WARN, state age-discrimination law, and statewide PFL, Mississippi severance recipients rely primarily on federal protections (ADEA / OWBPA, Title VII, ADA, FMLA, federal WARN).
