Missouri sits firmly in the employer-discretion tier of PTO law. No vacation mandate, no sick leave requirement, use-it-or-lose-it legal, and no required payout at termination unless your employer's written policy says so. What's distinctive about Missouri is its preemption statute — which actively blocks cities from passing their own sick leave or minimum wage rules, leaving the entire state on a single employer-friendly baseline. For workers, this makes understanding your specific company's written policy more important than in states with stronger statutory protections.
Missouri PTO Law — Quick Reference
Vacation Pay: Policy Is Everything in Missouri
Missouri has no statute treating accrued vacation as earned wages, unlike California, Illinois, or Massachusetts. Vacation pay is a discretionary benefit, and your rights depend entirely on what your employer has put in writing. Missouri courts will enforce a vacation payout promise in a handbook or offer letter as a contract — but they won't create an entitlement that doesn't exist in the policy.
Use-It-or-Lose-It: Legal and Common
Missouri employers can legally run use-it-or-lose-it vacation policies — year-end resets, rollover caps, anniversary forfeiture — as long as the policy is clearly stated. Missouri has no law protecting accrued vacation from forfeiture the way California's Labor Code does.
The most common Missouri structures: annual reset on December 31 or work anniversary; partial rollover (40–80 hour cap); no rollover and no payout at termination. Some larger Missouri employers — particularly those in healthcare, finance, and technology — offer more generous rollover and payout policies to compete for talent, but there's no legal floor.
Final Paycheck Rules
Missouri requires final paychecks on the next regular payday following separation, whether the employee was fired or quit. No accelerated timeline. Any vacation payout owed under policy must be included. Employers who willfully withhold owed wages face civil claims plus a penalty of up to 15 days' wages under Mo. Rev. Stat. §290.110.
For Employers: Missouri PTO Policy Best Practices
Missouri's lack of mandates gives employers flexibility — but vague policies create disputes. Core recommendations:
- State explicitly what happens to unused vacation at termination — forfeiture or payout
- If use-it-or-lose-it, specify the exact reset date and conditions
- Apply the policy consistently across employees — selective enforcement creates discrimination exposure
- Update policies in writing with advance notice before changing them
- Consider whether your voluntary sick leave policy adequately covers your workforce, even without a legal mandate

Does Missouri require vacation payout at termination?
Only if your employer's written policy promises it. Missouri has no statute requiring vacation payout. If your handbook or offer letter commits to payout, Missouri courts treat that as an enforceable contractual obligation. If the policy is silent or states forfeiture, you have no legal entitlement.
Does Missouri have paid sick leave?
No. Missouri has no statewide paid sick leave law, and its preemption statute (§67.1602) blocks cities from passing their own mandates. Kansas City attempted a sick leave ordinance in 2020; it did not survive legal challenge. As of 2026, sick leave in Missouri is entirely at employer discretion.
Is use-it-or-lose-it legal in Missouri?
Yes. Missouri employers can legally forfeit unused vacation at year-end or under other conditions, provided the policy is clearly communicated in writing. There is no Missouri law equivalent to California's prohibition on PTO forfeiture.
When must a Missouri employer issue a final paycheck?
On the next regular payday following separation — for both fired and resigned employees. Any vacation payout owed under company policy must be included. Willful withholding of wages can result in penalty wages of up to 15 days under Mo. Rev. Stat. §290.110.
Can Missouri cities require paid sick leave?
No. Missouri's preemption statute prevents cities and counties from enacting employment regulations that exceed state law. Both Kansas City and St. Louis have explored sick leave mandates; both have been blocked or preempted. Workers in Missouri cities have the same sick leave rights as workers statewide — which means none, beyond what employers voluntarily provide.
I have a Missouri PTO dispute. Where do I file a claim?
File a wage claim with the Missouri Department of Labor and Industrial Relations — Labor Standards Division — online at labor.mo.gov. The Division handles claims for unpaid wages, including promised vacation pay. For disputes over $100, you can also file in Missouri small claims court (up to $5,000) or hire a private employment attorney for larger amounts.
