TL;DR: Comp time (compensatory time) is paid time off earned instead of cash overtime pay, 1.5 hours of comp time for every overtime hour worked. Federal law allows it for state and local government employees under the Fair Labor Standards Act, subject to accrual caps and specific rules. For most private-sector, non-exempt employees, it's generally illegal, the FLSA requires overtime to be paid in cash, in the pay period it's earned, not banked as future time off. Here's exactly how comp time works, who can legally use it, and what happens to unused comp time when you leave a job.
Comp time sounds like a simple trade: work extra hours now, take equivalent time off later, everybody wins. [AGREE] That trade is only legal for certain employees, under specific conditions, and the rules trip up a lot of employers who assume it's a straightforward alternative to overtime pay. [PROMISE] This guide covers exactly who can legally earn comp time, how the accrual and payout rules work under the Fair Labor Standards Act, what happens when you hit the accrual cap, how comp time differs from PTO and flex time, and what to do if your private-sector employer is offering you comp time instead of overtime pay.

What Is Comp Time?
Comp time (short for compensatory time off) is paid time off that an employee earns in place of cash overtime pay. Under the standard formula, you earn 1.5 hours of comp time for every hour of overtime you work, mirroring the standard time-and-a-half overtime rate the FLSA requires for cash payment. In effect, it's deferred compensation: instead of getting paid extra now for the extra hours, you bank that value as future paid time off.
The concept sounds neutral on paper, but its legality depends heavily on who your employer is. This is the single most misunderstood part of comp time, and it trips up private employers more than any other wage-and-hour issue outside of misclassification.
Who Can Legally Use Comp Time
State and Local Government Employees
Comp time in lieu of cash overtime is explicitly authorized for state and local government employees under Section 7(o) of the FLSA, added by amendment in 1985. This is the provision most public-sector comp time programs, for police officers, firefighters, teachers' aides, and municipal workers, operate under. It comes with real conditions, covered below, not a blank check to substitute time off for cash whenever an agency prefers.
Federal Government Employees
Federal employees have their own comp time framework, separate from the state/local provision, governed by federal personnel law and regulations (including provisions in Title 5 of the U.S. Code and related OPM regulations) rather than the FLSA's Section 7(o). The mechanics differ somewhat by agency and by whether an employee is exempt or non-exempt from FLSA overtime rules, so federal employees should check their specific agency's policy rather than assuming the state/local rules apply directly to them.
Private-Sector, Non-Exempt Employees
For private-sector employers, the FLSA generally does not allow substituting comp time for cash overtime pay owed to non-exempt employees. The law requires overtime (time and a half for hours worked over 40 in a workweek) to be paid in cash, in the pay period it's earned. An employer that offers "comp time" instead of overtime pay to a non-exempt private-sector employee is very likely violating the FLSA, regardless of whether the employee agreed to the arrangement. Over the years, various bills (sometimes referred to as comp-time or "working families flexibility" proposals) have been introduced in Congress to extend a private-sector comp time option similar to the public-sector model, but you should not assume any such proposal has become law, check current federal law and consult the Department of Labor's Wage and Hour Division directly before relying on a private-sector comp time arrangement.
Exempt Employees (Any Sector)
Employees who are exempt from FLSA overtime requirements, most salaried employees meeting the executive, administrative, professional, or similar exemption tests, aren't legally entitled to overtime pay in the first place, so the FLSA's comp time restrictions don't apply to them the same way. Many employers informally offer exempt employees a day off after an unusually demanding stretch (a product launch, a busy season) as a goodwill gesture. This isn't "comp time" in the legal FLSA sense, it's simply a matter of company policy and manager discretion, with no statutory formula, accrual rules, or payout requirement behind it.
Comp Time Rules Under the FLSA (Public Sector)
For the state and local government employees who can legally use comp time, several specific rules apply:
It Must Be Agreed to in Advance
Comp time can't be imposed unilaterally by the employer after the fact. It has to be established through a collective bargaining agreement where one exists, or through an individual agreement or understanding reached with the employee before the overtime work is performed. An employer can't decide after the fact to give comp time instead of the cash overtime an employee was expecting.
Accrual Caps Apply
Public-sector comp time isn't unlimited. Federal regulations cap accrual at 240 hours for most employees. Employees classified as engaged in public safety, emergency response, or seasonal activities, police officers, firefighters, and EMS personnel are the classic examples, can accrue up to 480 hours. Once an employee reaches the applicable cap, any additional overtime worked must be paid in cash, not banked as more comp time.
Employers Must Let Employees Use It Within a Reasonable Time
An employee who requests to use accrued comp time is generally entitled to take it within a "reasonable period" after making the request, unless doing so would "unduly disrupt" the employer's operations. This standard gives agencies some flexibility to manage staffing, but it isn't a blank check to indefinitely deny comp time requests, the disruption has to be genuine, not just inconvenient.
Unused Comp Time Must Be Paid Out at Separation
When a public-sector employee leaves (whether by resignation, termination, or retirement) any unused comp time must be paid out in cash. The payout rate is the employee's final regular rate of pay, or the average regular rate over the employee's last three years of employment, whichever is higher. This protects departing employees from losing the value of banked overtime, similar in spirit to how accrued vacation payout rules work for traditional PTO in states that require it.
Comp Time vs. Overtime Pay vs. PTO
Feature | Cash Overtime | Public-Sector Comp Time | Traditional PTO |
|---|
Legal for private sector (non-exempt) | Required by FLSA | Generally not allowed | N/A, separate benefit |
Legal for public sector | Yes | Yes, under FLSA §7(o) | N/A, separate benefit |
Rate earned | 1.5x cash pay | 1.5 hours off per OT hour | Not overtime-based; usually accrues per pay period regardless of hours worked |
Accrual cap | None (must be paid each period) | 240 hours (480 for public safety/emergency/seasonal) | Varies by employer policy |
Paid out at termination | N/A, already paid | Yes, required | Often required by state law |
Requires advance agreement | No | Yes | No |
Comp time and PTO solve different problems: PTO is a general time-off benefit unrelated to hours worked, while comp time is specifically a substitute for overtime pay tied directly to extra hours logged. If you're trying to understand how a general time-off bank works instead, see our guide to what PTO means and PTO accrual.
What to Do If Your Private Employer Offers Comp Time Instead of Overtime Pay
If you're a non-exempt employee at a private company and your employer is offering comp time in place of cash overtime pay, treat that as a compliance red flag worth investigating, not a routine benefit:
Confirm your classification. Check whether you're actually exempt or non-exempt under the FLSA, this determines whether overtime rules even apply to you in the first place. Misclassification is a common underlying issue.
Ask HR directly how the policy is structured and whether it's been reviewed against current federal wage-and-hour law.
Document your hours and any comp time earned, in case you need to file a wage claim later.
Contact the U.S. Department of Labor's Wage and Hour Division if you believe you're not being paid overtime you're legally owed. Unpaid overtime claims can often recover back pay, and in some cases liquidated damages, going back up to two or three years depending on whether the violation is found to be willful.
Check your state's wage-and-hour laws too. Some states have their own overtime rules that are more protective than the federal FLSA floor, and state agencies can be another avenue for a complaint.
Common Misconceptions About Comp Time
"My employer said I agreed to it, so it must be legal." Agreement doesn't make an otherwise-illegal comp time arrangement legal for a private-sector non-exempt employee. FLSA overtime protections generally can't be waived by employee agreement, the cash-overtime requirement exists specifically because Congress didn't want it to be negotiable away under pressure from an employer.
"Comp time and overtime pay are financially equivalent, so it doesn't matter which I get." They're not risk-equivalent even if the dollar value is theoretically similar. Cash overtime pays you immediately and isn't subject to your employer's discretion about when you can use it. Comp time is a promise of future paid time off that depends on staffing needs, your employer's solvency, and (in the public sector) statutory caps and use-it rules.
"Comp time is the same as flex time." They're different concepts. Comp time is specifically tied to overtime hours worked beyond 40 in a workweek, with a fixed 1.5x accrual formula. Flex time, by contrast, usually refers to flexible scheduling of when you work your normal hours, not a substitute for overtime pay, see our guide to flexible time off for that distinct concept.
Frequently Asked Questions
What is comp time?
Comp time (compensatory time off) is paid time off earned instead of cash overtime pay. Under the standard federal formula, you earn 1.5 hours of comp time for every hour of overtime worked, the same rate that would otherwise apply to cash overtime pay under the Fair Labor Standards Act.
Is comp time legal in the private sector?
Generally no, for non-exempt employees. The FLSA requires private employers to pay overtime in cash, in the pay period it's earned, rather than substituting banked time off. There have been legislative proposals over the years to extend a private-sector comp time option, but you shouldn't assume such a proposal is current law, verify directly with the Department of Labor's Wage and Hour Division or an employment attorney before relying on a private-sector comp time arrangement.
Is comp time legal for government employees?
Yes. Section 7(o) of the Fair Labor Standards Act explicitly authorizes comp time for state and local government employees, subject to specific rules: it must be agreed to in advance, accrual is capped at 240 hours (480 for employees in public safety, emergency response, or seasonal roles), and unused comp time must be paid out in cash when the employee leaves.
How much comp time do you earn per overtime hour?
The standard formula is 1.5 hours of comp time for every hour of overtime worked, the same multiplier used for cash overtime pay. If you work 4 hours of overtime in a week, you'd earn 6 hours of comp time under this formula.
What happens to unused comp time when you leave your job?
For public-sector employees covered by the FLSA's comp time provision, unused comp time must be paid out in cash at separation, calculated at the employee's final regular rate of pay or their average regular rate over the last three years, whichever is higher. Some public employers also cap how much comp time an employee can accrue, which limits the maximum payout exposure.
Can my employer force me to take comp time instead of overtime pay?
No, in either sector. In the public sector, comp time has to be established through a collective bargaining agreement or an individual agreement reached before the overtime work is performed, an employer can't unilaterally impose it after the fact. In the private sector, non-exempt employees generally can't be given comp time instead of the cash overtime pay they're legally owed at all, regardless of agreement.
Does comp time expire?
Public-sector comp time isn't subject to a specific federal expiration date in the way "use it or lose it" vacation policies sometimes are, but it is subject to accrual caps , 240 hours for most employees, 480 hours for those in public safety, emergency response, or seasonal roles. Once an employee hits the applicable cap, additional overtime must be paid in cash rather than added to the comp time bank. Individual public employers may also set their own additional rules about scheduling comp time use, so check your specific employer's policy.
Can exempt (salaried) employees earn comp time?
Exempt employees aren't legally entitled to overtime pay under the FLSA in the first place, so the statutory comp time rules don't govern their situation the same way. Some employers informally give exempt employees extra time off after a demanding stretch of work as a discretionary goodwill gesture, but this isn't "comp time" in the legal FLSA sense, there's no required accrual formula, cap, or payout obligation behind it, since it's a matter of company policy rather than law.
What's the difference between comp time and PTO?
Comp time is earned specifically in exchange for overtime hours worked beyond 40 in a workweek, using a fixed 1.5-hour-per-overtime-hour formula. PTO is a general paid time-off benefit that typically accrues based on tenure or pay period, regardless of how many hours you've actually worked. They serve different purposes and are governed by different rules, comp time by the FLSA in the sectors where it's allowed, PTO largely by employer policy and state law.
What should I do if I think my employer is illegally giving me comp time instead of overtime pay?
Confirm whether you're classified as exempt or non-exempt under the FLSA, since that determines whether overtime rules apply to you at all. Document your actual hours worked and any comp time you've been given. Then raise the issue with HR, and if it isn't resolved, file a complaint with the U.S. Department of Labor's Wage and Hour Division or consult an employment attorney, unpaid overtime claims can often recover back pay going back two or three years, depending on whether the violation is found to be willful.
Can comp time be denied when I request to use it?
For public-sector employees, an employer generally has to let you use accrued comp time within a reasonable period after you request it, unless doing so would unduly disrupt the employer's operations. That standard gives some scheduling flexibility to the employer, but it isn't a blank check to indefinitely deny every request, the disruption has to be genuine and specific, not just a general preference to keep you working.
Do federal government employees follow the same comp time rules as state and local employees?
Not exactly. Federal employees operate under a separate comp time framework governed by federal personnel law and OPM regulations rather than the FLSA's Section 7(o), which applies specifically to state and local government employers. The general concept (banking overtime as future paid time off instead of cash) is similar, but the specific mechanics can differ by agency and by whether the employee is FLSA-exempt or non-exempt, so federal employees should check their own agency's policy rather than assuming the state/local rules apply directly.
