Severance pay in Missouri

  • 4.7% Missouri tax on your severance, plus 22% federal and 7.65% Social Security/Medicare.
  • Unemployment: up to $320 a week, for up to 20 weeks.
  • File your unemployment claim right away — it protects your claim start date.

In Missouri, three issues can change your first-month cash flow after a layoff: severance and unused vacation may be treated differently for unemployment, the claim effective date is the Sunday of the week you file, and payroll withholding is not the same as your eventual tax bill. Missouri also has a state income tax, so a separate severance check may include Missouri withholding as well as federal withholding and FICA.

Plain English

What severance means in Missouri

Missouri does not generally require an employer to provide severance or unused-vacation pay unless a contract, policy, or agreement requires it. Ask for the written separation agreement, payment date, whether pay is a lump sum or salary continuation, and how unused PTO is calculated.

For taxes, severance is generally wage income. The 22% federal and 4.7% Missouri figures are payroll-withholding methods, not guaranteed final tax rates. Your final liability depends on filing status, deductions, credits, Missouri residency and source rules, payment structure, and total annual income; severance may also affect unemployment weeks differently from PTO or salary continuation.

A worked example

The assumptions
  • Missouri resident, single, age under 65
  • Salary $60,000 annually, paid biweekly; approximate weekly pay $1,153.85
  • Two years with employer
  • Severance equals four weeks of salary: 4 x $1,153.85 = $4,615.40
  • Paid as one separately identified lump-sum supplemental wage payment
  • Missouri withholding assumption: 4.7% of supplemental wages
  • Federal withholding assumption: 22% of supplemental wages
  • FICA assumption: 7.65%; Social Security wage base not already reached
  • No extra withholding, credits, deductions, retirement contributions, or benefit deductions included
Estimated withholding
Gross severance$4,615.40
Federal (22%)-$1,015.39
FICA (7.65%)-$353.08
Missouri state (4.7%)-$216.92
Illustrative take-home $3,030.01

Benefits

Unemployment in Missouri

01You generally must be unemployed through no fault of your own, be able and available for work, and satisfy Missouri's base-period wage test. For a claim beginning July through September 2026, the regular base period is April 1, 2025 through March 31, 2026. The standard wage test requires at least $2,250, including $1,500 in one quarter and $750 in the remainder, plus total wages of at least 1.5 times the highest quarter; an alternative test may apply.

02Missouri calculates the weekly benefit amount as 4% of the average of the two highest base-period quarters, rounded down to an even dollar, capped at $320. The first eligible week is an unpaid waiting week. Report gross wages and applicable PTO, holiday, and WARN pay each week; Missouri law and DES guidance treat lump-sum severance as prorated for eligibility, while DES says severance and termination pay do not reduce the WBA in the same way as vacation pay. File promptly and let DES decide how your payment arrangement affects particular weeks.

Your first 72 hours

  1. 01
    Save the separation letter, severance agreement, final paystub, PTO balance, benefits notice, and employer contact details.
    DES may need the exact separation reason, payment dates, wages, and whether pay is severance, vacation, WARN, or salary continuation.
  2. 02
    File a Missouri UI claim in UInteract immediately after separation, even if severance is pending.
    The claim becomes effective Sunday of the filing week; delaying can lose claim-week timing and delay payment.
  3. 03
    Calendar the weekly request for payment, starting after the claim week ends.
    Requests must be filed every week, including the waiting week, and generally within 14 days after the Saturday week-end.
  4. 04
    Create a work-search record and complete at least three qualifying activities each week unless DES directs otherwise.
    Missouri generally requires three weekly activities and may deny benefits when they are not completed or recorded.
  5. 05
    Report gross wages, vacation or holiday pay, WARN pay, and any part-time work exactly for the week earned.
    Missouri deducts some payments from benefits and requires gross—not take-home—earnings reporting.
  6. 06
    Compare COBRA with Marketplace coverage and act within 60 days of losing job-based coverage.
    COBRA and the Marketplace have separate election processes; missing the Marketplace special-enrollment window can leave fewer affordable options.
Common questions

Missouri severance FAQ

Does Missouri require my employer to pay severance or unused vacation?

Generally no, unless a contract, policy, or agreement creates that obligation. Ask for the governing policy and check whether the final paycheck separately identifies PTO, severance, WARN, or salary continuation.

Can a Missouri lump-sum severance payment delay unemployment?

It may affect the weeks to which the payment is allocated. Missouri law says lump-sum severance is prorated weekly at the termination pay rate for unemployment eligibility; report it and let DES determine the claim-week effect.

Does unused PTO reduce Missouri unemployment?

Generally, vacation and holiday pay are reportable and can reduce the weekly benefit like wages. DES says severance and termination pay do not reduce the WBA in the same way, so do not combine all separation payments under one label.

If I file on Friday in Missouri, when does my claim start?

If the claim is otherwise established, its effective date is the Sunday of the week in which you file—not the last day worked. File promptly rather than waiting for the first severance check.

How many Missouri work-search activities do I need?

Generally at least three each week unless DES directs otherwise or an approved exception applies. Record applications, interviews, job-center activity, workshops, and other qualifying contacts in UInteract.

Can I receive Missouri unemployment while working part time?

Possibly. Report gross wages for the Sunday-through-Saturday week. Missouri generally allows the greater of $20 or 20% of the WBA before earnings are deducted, subject to the agency's calculation and eligibility rules.
