Iowa Severance — Iowa WARN 25+, Flat 3.8% Tax, 2026

Iowa WARN: what applies#

Iowa has a state mini-WARN — the Iowa Worker Adjustment and Retraining Notification Act, Iowa Code Chapter 84C. Iowa WARN applies to employers with 25 or more employees and requires 30 calendar days advance notice before a plant closure or mass layoff to affected employees, the Iowa Workforce Development (IWD) Rapid Response unit, and the chief elected official of the local government. Iowa's 25-employee threshold is markedly lower than federal WARN's 100-FTE trigger, and the 30-day notice is half the federal 60-day requirement — but Iowa WARN's primary added obligation captures small and mid-size employers (25–99) too small for federal WARN. Employers covered by BOTH federal WARN (100+ FTE) and Iowa WARN (25+) must comply with the longer federal 60-day notice. Federal WARN (29 U.S.C. §§ 2101–2109) applies to Iowa employers of 100+ with the standard federal triggers (50+ affected at a single site constituting at least 33% of the active workforce, or 500+ regardless of percentage). 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.

How severance is taxed in Iowa#

Iowa's individual income tax converted to a single FLAT 3.8% rate effective January 1, 2026 under Senate File 2442 of 2024 (signed by Governor Reynolds May 1, 2024), accelerating the prior SF 2417 of 2022 glidepath by one year — Iowa's pre-reform graduated brackets ran 0.33%–8.53% before the 2018 base reduction, compressed to four brackets (4.4% / 4.82% / 5.7% / 6.0%) for 2023, three brackets (4.4% / 4.82% / 5.7%) for 2024, flat 3.8% for 2025, and continuing flat 3.8% for 2026. The Iowa Department of Revenue's 2026 Iowa Withholding Tax Information directs employers to withhold at the highest individual rate of 3.8% on supplemental wages (severance, bonuses, commissions) when federal income tax is withheld at a flat rate on the same payment. Iowa does not impose a separate state-level local income tax on wages (some Iowa SCHOOL DISTRICTS levy a school district surtax computed as a percentage of state income tax due, reconciled on the year-end Iowa return). On top of Iowa 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 Iowa require severance pay?

No Iowa statute requires private employers to pay severance. Iowa WARN (Iowa Code Chapter 84C) is a NOTICE statute, not a severance mandate — it requires 30 days advance notice (or pay-in-lieu if notice is not given) at employers of 25+ for plant closures and mass layoffs, but does not require employers to pay severance. Severance is therefore employer-discretionary in Iowa unless your employment agreement, written severance plan, or company handbook makes it mandatory. Iowa is an at-will employment state.

How is severance taxed in Iowa?

Iowa converted to a single flat individual income tax rate of 3.8% effective January 1, 2026 under Senate File 2442 of 2024 (signed by Governor Reynolds May 1, 2024), which accelerated the prior SF 2417 of 2022 glidepath by one year. The Iowa Department of Revenue's 2026 Iowa Withholding Tax Information directs employers to withhold supplemental wages (severance, bonuses, commissions) at the highest individual rate of 3.8% when federal income tax is withheld at a flat rate on the same payment. If the supplemental wage is paid together with regular wages on a single payment and not separately identified, the combined amount is taxed using Iowa's regular withholding tables (which also produce a 3.8% effective rate above the standard deduction). Iowa imposes no state-level local income tax on wages — though several Iowa SCHOOL DISTRICTS levy a school district surtax computed as a percentage of the resident's state income tax liability, reconciled on the year-end Iowa return. On top of Iowa 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 Iowa liability is reconciled on Form IA 1040.

Does Iowa have a mini-WARN statute?

Yes — and Iowa's mini-WARN is one of the most distinctive features for small-employer layoffs. The Iowa Worker Adjustment and Retraining Notification Act (Iowa Code Chapter 84C) applies to employers with 25 or more employees and requires 30 calendar days advance notice to affected employees, the Iowa Workforce Development (IWD) Rapid Response unit, and the chief elected official of the local government before a plant closure or mass layoff. Iowa's 25-employee threshold is markedly lower than federal WARN's 100-FTE trigger, and the 30-day notice is half the federal 60-day requirement — but Iowa WARN's primary added obligation captures small and mid-size employers (25–99 employees) too small for federal WARN. Iowa WARN also serves a Rapid Response/Dislocated Worker Unit coordination function: the IWD Rapid Response team uses notices to deploy on-site reemployment services, unemployment-insurance briefings, and retraining-funding navigation to affected employees before separation. Employers covered by BOTH federal WARN (100+ FTE) and Iowa WARN (25+) must comply with the more stringent federal 60-day notice obligation. Verify the live text of Iowa Code Chapter 84C via legis.iowa.gov before relying on specific thresholds or penalties.

Does OWBPA apply in Iowa?

Yes. OWBPA is federal (29 U.S.C. § 626(f)) and applies in all states. If you are age 40 or older and your Iowa 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. The Iowa Civil Rights Act (Iowa Code Chapter 216) separately prohibits age discrimination (18+) by employers with 4 or more employees — a substantially lower threshold than the federal ADEA's 20-employee minimum, so smaller Iowa employers are still covered by state law. A release of state-law age claims under the ICRA does not require OWBPA-compliant 21/45/7 procedures, but the federal ADEA release portion still does.

Can I collect Iowa unemployment while receiving severance?

Iowa is one of the strictest states for severance-and-unemployment overlap. Severance pay is FULLY DEDUCTIBLE from Iowa UI benefits on a dollar-for-dollar basis under Iowa Administrative Code rule 871-24.13(1) — 'Wages in lieu of notice, separation allowance, severance pay, and dismissal pay' are 'fully deductible from benefits.' In practice, Iowa Workforce Development (IWD) allocates lump-sum severance week-by-week at the claimant's normal weekly wage and reduces UI dollar-for-dollar during the allocated weeks until the severance is exhausted — once exhausted, full UI resumes (subject to other eligibility). Iowa Code § 96.5 governs disqualification conditions. Practical takeaways: (a) file your Iowa UI claim with IWD on or shortly after your last day worked at workforce.iowa.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) confirm the current Iowa UI maximum weekly benefit amount with IWD before relying on net-of-benefits figures.

Are non-competes enforceable in Iowa after a layoff?

Often yes if reasonable — Iowa has no statute governing employer non-competes, and the controlling framework is the common-law 'reasonableness' test articulated by the Iowa Supreme Court in Lamp v. American Prosthetics, Inc., 379 N.W.2d 909 (Iowa 1986), refined in Iowa Glass Depot, Inc. v. Jindrich, 338 N.W.2d 376 (Iowa 1983), and applied in modern cases. Under this framework, a non-compete is enforceable if it is (1) reasonably necessary to protect the employer's legitimate business interest (trade secrets, confidential information, customer relationships, goodwill), (2) reasonable in time and geographic scope, and (3) not unduly oppressive to the employee or against public policy. Iowa courts have judicial blue-pencil authority to narrow overbroad covenants. Practical takeaway: in Iowa, 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. Have an attorney review duration, geography, and scope before signing.

Why is Iowa unusual for severance-UI overlap?

Iowa is one of a small handful of states (along with Ohio under § 4141.31(A), and a few others) that treats severance as fully deductible from UI benefits on a dollar-for-dollar basis. Iowa Administrative Code rule 871-24.13(1) explicitly lists 'wages in lieu of notice, separation allowance, severance pay, and dismissal pay' as fully deductible. In practice, this means Iowa allocates lump-sum severance week-by-week at the claimant's normal weekly wage and reduces UI benefits dollar-for-dollar during the allocated weeks until the severance is exhausted. The practical effect: if your severance equals 12 weeks of pay, you typically receive zero Iowa UI for those 12 weeks even if you are otherwise eligible — but full UI resumes once the severance is exhausted (subject to other eligibility requirements). Contrast with California (Cal. UI Code § 1265: severance does NOT reduce UI), Massachusetts (lump sum at separation generally does not delay; allocated salary continuation does), and New Jersey (severance does not delay UI). If you have negotiating leverage on severance structure, lump sums in Iowa are not more favorable than salary continuation for UI purposes — both are allocated week-by-week.
