In Colorado, any vacation or paid time off (PTO) you have already earned must be paid to you when your employment ends, and an employer cannot make you forfeit it. The Colorado Wage Act treats earned vacation pay as wages, and the Colorado Supreme Court confirmed in Nieto v. Clark's Market (2021) that a “use-it-or-lose-it” policy cannot wipe out vacation that has already accrued once you separate. That makes Colorado one of the stronger states for departing workers, and it differs sharply from states that let employers cancel unused vacation entirely.
Colorado's Core Rule: Earned Vacation Is Wages
The Colorado Wage Act (C.R.S. 8-4-101 and following) defines “wages or compensation” to include vacation pay earned in accordance with the terms of an agreement. Because earned vacation is legally a form of wages, it is owed at separation just like your regular paycheck. An employer cannot keep vacation you have already earned simply because you quit, were laid off, or were fired.
The Colorado Department of Labor and Employment (CDLE) has interpreted this protection to cover general PTO banks as well as traditional vacation time, since PTO that can be used like vacation functions as earned vacation pay. The key question is always the same: has the time been earned (accrued) under the employer's policy? If yes, it must be paid out.
Are Use-It-or-Lose-It Policies Legal in Colorado?
This is where Colorado is distinctive. A pure use-it-or-lose-it policy that forfeits already-earned vacation at the moment you leave is not enforceable. In Nieto v. Clark's Market, the Colorado Supreme Court held that whatever vacation pay an employee has earned and that is determinable cannot be forfeited at termination, regardless of what the policy says. Contract language attempting to cancel earned vacation at separation does not override the Wage Act.
However, the law leaves employers meaningful flexibility on the front end:
- No requirement to offer vacation at all. Colorado law does not force an employer to provide vacation or PTO. If none is offered, there is nothing to pay out.
- Accrual caps are allowed. An employer can lawfully cap how much vacation you accumulate (for example, stop accrual once your balance hits a set number of hours). This limits what you build up, but it does not forfeit what you have already earned.
- The written policy defines how time is earned. Eligibility waiting periods, accrual rates, and similar terms generally control—up to the point that time becomes earned and vested.
The line is between limiting how vacation is earned (allowed) and taking back vacation you already earned (not allowed). A policy can slow or cap accrual; it cannot retroactively erase an earned balance when you walk out the door.
How the Written Policy Controls
Your employer's written vacation or PTO policy is the starting point for determining what you are owed. It sets the accrual rate, any caps, eligibility rules, and how time is tracked. Read it carefully, because it usually decides how much vacation you have earned as of your last day.
What the policy cannot do is include a forfeiture clause that nullifies earned vacation at separation—those clauses are unenforceable under Colorado law. So if your handbook says “all unused vacation is forfeited upon termination,” that language does not control over your statutory right to be paid for time you already accrued.
One important distinction: paid sick leave is treated differently. Under Colorado's Healthy Families and Workplaces Act (HFWA), employers must provide paid sick leave, but accrued sick leave generally does not have to be paid out at separation. The vacation/PTO payout rule discussed here applies to vacation-style time off, not to dedicated sick leave.
When Must Colorado Pay Your Final Wages?
Earned vacation is paid as part of your final wages, and Colorado sets firm deadlines:
