Compensatory Time Off (Comp Time)

Comp time is one of the most misunderstood payroll concepts in the U.S. It sounds like a flexible, employee-friendly alternative to overtime pay (take a day off next week instead of getting paid time-and-a-half now), and for public sector workers, it is exactly that. For private sector employers, offering comp time to non-exempt employees in place of overtime is illegal under the Fair Labor Standards Act. This trips up plenty of private companies that think they're doing employees a favor. The FLSA has been clear since 1985: comp time is a public-sector-only tool.

How Comp Time Legally Works in the Public Sector

The FLSA allows state and local government employers and federal agencies to give comp time instead of cash overtime, but only under specific conditions. The employee and employer have to agree to the arrangement in advance, ideally in writing. Comp time accrues at the same 1.5x rate overtime pay would: one hour of overtime earns 1.5 hours of comp time off.

Accrual caps apply. Most public sector employees can accrue up to 240 hours of comp time (equivalent to 160 overtime hours worked). Police, fire, and emergency response can accrue up to 480 hours because of the irregular demands of their work.

Why Comp Time Is Illegal in the Private Sector

Congress has debated comp-time-for-private-sector legislation since the 1990s, and bills regularly pass the House but stall in the Senate. As of 2026, the ban remains. Private employers who offer non-exempt employees comp time in place of overtime pay violate the FLSA, triggering back-wage liability plus potential liquidated damages.

The one partial exception: exempt employees (salaried workers who don't earn overtime anyway) can receive additional paid time off when they work extra hours. This isn't technically comp time, it's discretionary PTO, and it doesn't fall under the same FLSA rules.

What's the Difference Between Comp Time and PTO?

PTO (paid time off) is paid leave employees earn based on their employment agreement, separate from any overtime work. Comp time is paid leave specifically earned in lieu of overtime pay, and only public sector non-exempt workers can get it under federal law. The distinction matters because FLSA rules apply to comp time but not to PTO.

How Public Sector Employers Run a Comp Time Program

Agencies using comp time need clear written policy, agreement between employer and employee before the overtime happens, accurate tracking of accrual and use, and payout of unused comp time at separation at the higher of the current hourly rate or the average rate over the last 3 years. Accuracy matters because DOL audits frequently target comp time records.

Employers also have to honor reasonable requests to use comp time when the employee asks, unless doing so would unduly disrupt operations. Courts have repeatedly rebuffed employers who denied comp time use because it was merely inconvenient rather than truly disruptive.

Staying Compliant With Compensatory Time Off Rules

The practical checklist for a public sector employer: write a comp time policy into the employee handbook, document agreement in writing before each overtime opportunity, track accruals separately from PTO in the HRIS, pay out balances at separation, and run periodic internal audits to verify compliance. For private employers, confirm that no manager is offering comp time to non-exempt staff (the offer alone can create FLSA exposure if accepted).
