This page covers PTO carryover and year-end rollover rules in Missouri for 2026 — including what your employer can and cannot do with your unused balance, how accrual caps differ from forfeiture, and practical steps to protect your earned time.
Can Your Employer Enforce Use-It-or-Lose-It in Missouri?
Use-it-or-lose-it policies are permitted in Missouri if clearly stated in the employer written policy.
Accrual Caps vs. Forfeiture — Critical Difference
| Policy type | Legal in Missouri? | What it means for you |
|---|---|---|
| Accrual cap | Yes — always legal | You stop earning new PTO at the cap, but existing balance stays intact |
| Use-it-or-lose-it (with advance notice) | Yes, if clearly written in advance before PTO is earned | Unused PTO forfeited at year-end if policy clearly stated this before PTO was earned |
| Retroactive forfeiture | Not allowed anywhere | Employer cannot zero out PTO you already earned without prior written notice |

Paid Sick Leave Carryover in Missouri
No statewide paid sick leave mandate in Missouri. Several cities including St. Louis and Kansas City have passed local sick leave ordinances.
Note: Sick leave and vacation/PTO carryover are governed by separate rules. In most states with mandatory paid sick leave, unused sick hours must carry over year to year — even if vacation hours do not.
Year-End PTO Planning Checklist for Missouri Employees
- Check your balance in November — log into your HR portal or check your last pay stub
- Review your handbook year-end policy — look for "forfeiture date," "carryover cap," "rollover maximum," or "December 31 deadline"
- Calculate how many days you need to use — use our hours-to-days calculator
- Request time off before the deadline — note that your employer can deny requests for staffing reasons
- If policy changed mid-year — confirm in writing what happens to PTO earned before the policy change date
