Colorado PTO Laws: What Employers Must Know (2026)
Colorado treats earned vacation as wages that cannot be forfeited, and mandates paid sick leave. What Nieto v. Clark's Market changed for every handbook.
Colorado changed decisively in 2021, and a lot of handbooks in the state still have not caught up.
Before then, many employers ran ordinary use-it-or-lose-it vacation policies and paid nothing out at termination. Then the Colorado Supreme Court decided Nieto v. Clark's Market, and the rule became simple: earned vacation is wages, and wages cannot be forfeited.
If your Colorado policy still contains a forfeiture clause, it is not merely outdated. It is unenforceable, and the Wage Act carries penalties.
This is general information rather than legal advice — confirm current requirements with the Colorado Department of Labor and Employment or an employment attorney before finalizing a policy.
What Colorado actually requires
Two mandates, plus one large prohibition.
Paid sick leave is mandatory. Under the Healthy Families and Workplaces Act, employees accrue one hour per 30 hours worked, up to at least 48 hours per year. This applies to employers of every size, including very small teams, and covers part-time staff.
Public health emergency leave sits on top. When a public health emergency is declared, employees become entitled to a supplemental block — up to 80 hours for full-time staff — separate from the ordinary 48.
Vacation is not mandatory, but forfeiture is banned. Nothing requires you to offer vacation. Offer it, and every hour earned becomes wages.
The Nieto rule and what follows from it
The holding is narrow to state but broad in effect: an agreement to forfeit earned vacation pay is void, and it does not matter whether the employee signed it.
Three consequences:
1. No expiry at year end
"Unused vacation expires 31 December" is unenforceable. You cannot delete earned wages because the calendar turned.
2. No forfeiture at termination
Payout is required on separation for any reason — resignation, dismissal, or layoff. A policy conditioning payout on giving two weeks' notice, or on leaving in good standing, does not survive.
3. Caps are still legal
This is the part employers miss, and it is the practical escape valve. You may cap the balance, so that accrual pauses once someone reaches a ceiling. Nothing earned is removed — the employee keeps every hour and resumes accruing as soon as they use some.
| Annual vacation | Common cap range |
|---|---|
| 10 days (80 hours) | 120–160 hours |
| 15 days (120 hours) | 180–240 hours |
| 20 days (160 hours) | 240–320 hours |
PTO accrual caps covers how to set one that actually holds. A cap so low that forfeiture becomes inevitable invites the argument that it is disguised forfeiture.
Cap, do not delete
Sick leave versus vacation: why the buckets matter
HFWA sick leave does not have to be paid out at separation. Vacation does. That asymmetry is the entire argument for keeping two balances.
| Separate sick + vacation | One combined PTO bank | |
|---|---|---|
| Payout at termination | Vacation portion only | Entire balance |
| Carryover | Sick carries to 48 hrs | Whole balance carries |
| Admin overhead | Two balances | One balance |
| Liability on the books | Lower | Higher |
Merging everything into one bank is simpler and popular with employees. In Colorado it also converts your sick leave into payable wages. For a 25-person team that difference can run into five figures of accrued liability.
The PTO cost calculator will show you what your current balances are worth if everyone left tomorrow, which is the number the combined-bank decision actually turns on.
FAMLI: the third thing on the paycheck
Colorado's Family and Medical Leave Insurance program pays partial wage replacement for bonding, serious health conditions, and safe leave. It is funded by a shared premium and administered by the state.
It is not a balance you track, and it is not a substitute for HFWA sick leave. Handbooks that describe FAMLI as though it were company leave create expectations you cannot meet, because eligibility and benefit amounts are determined by the state, not by you.
Accrual mechanics that catch people out
Accrual is hours-based, not monthly. One hour per 30 worked means a 45-hour week accrues faster than a 35-hour week. A flat "3.33 hours per month" grant will under-provide for anyone working overtime.
Front-loading is allowed. You may grant the full 48 hours at the start of the year instead of accruing. This is simpler and often cheaper in administration, and it removes the carryover question entirely. Front-loaded vs accrued PTO compares the two approaches.
Carryover is required for accrued sick leave up to 48 hours, unless you front-load.
Rehires within six months generally get their prior sick-leave balance restored.
A quick handbook audit
Read your Colorado policy and check for these five phrases. Each one is a problem:
- "Unused vacation expires" — unenforceable
- "Forfeited upon termination" — unenforceable
- "Payout requires two weeks' notice" — unenforceable
- "Doctor's note required for any absence" — HFWA restricts verification for short absences
- "Sick leave is combined with vacation" — legal, but converts sick leave into payable wages
Replace the first three with an accrual cap and an unconditional payout clause. That single edit resolves most Colorado exposure.
Tracking it accurately
Colorado is one of the states where the accrued balance is a real financial liability sitting on your books, not just an HR number. Every hour is money owed on the day someone resigns.
That makes accuracy worth more here than in a state like Texas. Hours-based accrual, a balance cap that pauses rather than deletes, sick leave carryover at 48 hours, and a payout figure at the final rate of pay — those four rules interact in ways that spreadsheets handle badly.
Run your numbers through the PTO payout calculator to see what a single departure costs today, and read calculating PTO payout at termination for the mechanics of getting the final-rate calculation right.
Frequently asked questions
Is PTO required by law in Colorado?
Paid vacation is not required. Paid sick leave is. Under the Healthy Families and Workplaces Act, Colorado employers must provide one hour of paid sick leave per 30 hours worked, up to at least 48 hours per year. Vacation is optional, but heavily regulated once offered.
Can Colorado employers use use-it-or-lose-it PTO?
No. The Colorado Supreme Court held in Nieto v. Clark's Market (2021) that earned vacation is wages under the Colorado Wage Act and cannot be forfeited. A clause deleting unused vacation at year end or at termination is unenforceable.
Does Colorado require vacation payout at termination?
Yes. All earned and determinable vacation pay must be paid out when employment ends, regardless of the reason for separation and regardless of what your handbook says. Agreements to forfeit it are void.
Can Colorado employers cap vacation accrual?
Yes. Capping how much an employee can accrue is legal because nothing already earned is taken away — accrual simply pauses at the ceiling and resumes once time is used. This is the compliant alternative to use-it-or-lose-it.
Does Colorado paid sick leave have to be paid out?
No. HFWA sick leave does not need to be paid out at separation, which is the main practical argument for keeping sick leave in a separate bucket from vacation rather than merging both into one PTO bank.
