Colorado occupies an interesting middle ground in U.S. PTO law. It's not as employee-protective as California — but it goes significantly further than most states. Under the Colorado Wage Act and the Division of Labor Standards and Statistics' Wage Protection Rules, earned vacation is a form of wages — and the Colorado Supreme Court held in Nieto v. Clark's Market (2021) that an agreement making earned vacation forfeitable is void. That has significant consequences for how employers can write their PTO rules.

Colorado also has mandatory paid sick leave under the Healthy Families and Workplaces Act (HFWA), passed in 2020, which applies to nearly every employer in the state. Here's what you need to know in 2026.

Accrued Vacation as Earned Wages: Colorado's Key Rule

The foundation of Colorado PTO law is the Colorado Wage Act (C.R.S. § 8-4-101 et seq.) and the Wage Protection Rules the Division of Labor Standards and Statistics issues under it (7 CCR 1103-7). The operative provision is C.R.S. § 8-4-101(14)(a)(III), which counts as wages "vacation pay earned in accordance with the terms of any agreement," and adds: "If an employer provides paid vacation for an employee, the employer shall pay upon separation from employment all vacation pay earned and determinable in accordance with the terms of any agreement between the employer and the employee."

The Colorado Supreme Court settled what that means in Nieto v. Clark's Market, Inc., 2021 CO 48 (14 June 2021). The employer there had a handbook clause denying any vacation payout to an employee who left without giving two weeks' written notice. The Court held that once vacation is earned, an agreement purporting to forfeit it is void — an employer cannot condition payout of already-earned vacation on how the employee leaves.

This means that a standard year-end "use it or lose it" policy — where unused vacation simply disappears on December 31 — is generally prohibited in Colorado. The Division of Labor has consistently interpreted the Wage Claim Act to prohibit policies that cause employees to forfeit already-accrued vacation.

⚠️ Important Distinction: Accrual Caps vs. Forfeiture Colorado law prohibits forfeiture of earned vacation but does allow accrual caps. An employer can say "you stop earning new PTO once you hit 120 hours" — that's a cap on future accrual, not a forfeiture of what you've already earned. What's prohibited is a policy that says "your 80 hours of accrued vacation disappears on January 1." Know the difference.

Vacation Payout at Termination

Because earned vacation is wages, Colorado requires employers to pay out all earned vacation at the end of employment — whether the employee quits, is laid off, or is terminated for cause. The payout is due in the final paycheck. An employer still controls the terms on which vacation is earned in the first place (it can decline to offer vacation at all, or provide that none accrues during an initial period). What it cannot do, after Nieto, is attach a condition that forfeits vacation the employee has already earned.

📋 Colorado Final Pay Requirements

Involuntary termination: Final pay (including the vacation payout) is due immediately. C.R.S. § 8-4-109 allows two narrow exceptions: if the payroll unit is not operating when you are let go, the employer has until six hours into its next regular workday, or 24 hours if the payroll unit is off-site.

Voluntary resignation: Final pay is due by the next regular payday.

What must be paid: All earned vacation at the employee's final wage rate.

If an employer doesn't pay: File a wage claim with the Colorado Division of Labor Standards and Statistics — and send a written demand, because it starts a clock. Under C.R.S. § 8-4-109(3), if the employer still has not paid 14 days after a written demand, it owes the wages plus the greater of twice the unpaid wages or $1,000. If the failure to pay was willful, that rises to the greater of three times the unpaid wages or $3,000, and a prior wage judgment or a repeat violation within five years counts as willful.

One important nuance: employers can include a waiting or vesting period in their policy before vacation begins to accrue or before an employee is eligible to be paid out. For example, a policy can state "employees do not accrue vacation during the first 90 days." That's legal — vacation hasn't been earned yet during that window. What's not legal is clawing back vacation the employee has already accrued.

Colorado Healthy Families and Workplaces Act (HFWA): Paid Sick Leave

The HFWA, effective January 1, 2021 for employers with 16+ employees and January 1, 2022 for all employers, mandates paid sick leave for virtually all Colorado workers. In 2026, the rules are fully in effect.

📋 HFWA Paid Sick Leave — 2026 Requirements

Accrual: 1 hour of paid sick leave for every 30 hours worked, up to 48 hours (6 days) per year.

Front-loading option: Employers may front-load 48 hours at the start of the year instead of tracking accrual.

Carryover: Employees may carry over up to 48 hours of unused sick leave to the next year.

When usable: Employees may use sick leave as it accrues (no waiting period for use, unlike Washington's 90-day rule).

Payout at termination: Not required.

The "Use-It-or-Lose-It" Question in Colorado

Colorado's prohibition on vacation forfeiture is stricter than most people realize. The Colorado Division of Labor has taken the position that an employee cannot be required to forfeit accrued vacation under a use-it-or-lose-it policy. However, this doesn't mean employers can't manage vacation aggressively — they can use accrual caps to limit accumulation.

📊 Legal vs. Illegal Policy Structures in Colorado

❌ Illegal: "All unused vacation is forfeited at December 31 each year."

❌ Illegal: "If you don't use vacation by your anniversary date, it's gone."

✅ Legal: "Vacation accrual stops once you reach 120 hours. You won't earn more until you use some and drop below the cap."

✅ Legal: "Employees do not accrue vacation during their first 90 days of employment."

✅ Legal: "Vacation must be scheduled and approved in advance; it cannot be carried over indefinitely, but you won't lose what you've already earned."

💡 Tip for Colorado Employees If your employer has a written "use it or lose it" policy, that policy is likely unenforceable under Colorado law. If you've had vacation canceled or forfeited, you may be able to recover those wages through a wage claim with the Division of Labor Standards and Statistics at colorado.gov/cdle.

For Employers: Colorado Compliance Essentials

Colorado's treatment of vacation as earned wages is a compliance trap for employers who copy policies from other states. The most common mistakes:

HR software with Colorado-specific wage law configurations can flag policy issues automatically. Gusto, Rippling, and BambooHR all have Colorado-aware PTO and sick leave modules that can be configured to enforce accrual caps rather than forfeiture rules, and to automate final paycheck calculations to include vacation balances.

Frequently Asked Questions

Does Colorado require employers to offer paid vacation?

No. Colorado does not require employers to provide vacation time. The state's protections kick in only once an employer has chosen to offer vacation — at that point, accrued vacation becomes earned wages and cannot be forfeited. If your employer offers no vacation, that's legal. If they offer vacation and then try to claw it back, that's not.

My employer's handbook has a use-it-or-lose-it policy. Is that enforceable in Colorado?

Almost certainly not. The Colorado Division of Labor has consistently interpreted the Wage Claim Act to prohibit forfeiture of accrued vacation. If you've had vacation canceled under such a policy, you may be entitled to recover it. Start by raising it with HR in writing; if they refuse, file a wage claim with the Colorado Division of Labor Standards and Statistics (CDLE).

How much paid sick leave am I entitled to under Colorado law?

Under the Healthy Families and Workplaces Act, you accrue 1 hour of paid sick leave per 30 hours worked, up to 48 hours (6 days) per year. Unused sick leave carries over, but your employer can cap the total balance you can use in a year at 48 hours. There's no waiting period — you can use sick leave as you accrue it.

My employer fired me and didn't include my vacation balance in my final paycheck. What do I do?

File a wage claim with the Colorado Division of Labor Standards and Statistics at colorado.gov/cdle. For involuntary terminations, final pay including earned vacation is due immediately (with narrow six- and 24-hour exceptions where the payroll unit is not running or is off-site). Send a written demand: under C.R.S. § 8-4-109(3) an employer that has not paid 14 days after one owes the wages plus the greater of twice the unpaid wages or $1,000, rising to the greater of three times or $3,000 where the failure is willful. You can also consult an employment attorney — many handle Colorado wage claims on contingency.

Can my Colorado employer require me to use vacation before taking FMLA or PFML leave?

For unpaid federal FMLA leave, yes — federal law lets an employer require accrued paid leave to run concurrently. For Colorado FAMLI, no, and this is the opposite of what many handbooks say. An employer may not require you to use accrued PTO before or while you receive FAMLI benefits. PTO can be used to "top up" a FAMLI benefit toward full pay, but only by a signed written agreement between you and your employer, and the combined total may not exceed your average weekly wage. If you would rather keep your PTO for later, you cannot be made to spend it.

Does Colorado have a state paid family leave program?

Yes. Colorado's FAMLI (Family and Medical Leave Insurance) program launched benefits on January 1, 2024. It provides up to 12 weeks of paid leave (16 weeks where there are pregnancy or childbirth complications). The benefit replaces 90% of the part of your average weekly wage at or below 50% of the state average weekly wage — $767.47 — and 50% of the part above it, subject to a maximum weekly benefit of $1,381.45 through 30 June 2026, rising to $1,448.02 for claims beginning on or after 1 July 2026. It is funded by payroll premiums, 0.88% of wages for 2026, split evenly between employer and employee, and administered by the Colorado Department of Labor and Employment.
