5 CFR 550.1407 - Forfeiture of unused compensatory time off.
(a)After 26 pay periods.
(1) Except as provided in paragraphs (a)(2) and (e) of this section, an employee must use accrued compensatory time off by the end of the 26th pay period after the pay period during which it was earned. If an employee fails to use the compensatory time off within 26 pay periods after it was earned, he or she must forfeit such compensatory time off.
(2) If an employee with unused compensatory time off separates from Federal service or is placed in a leave without pay status in the following circumstances and later returns to service with the same (or successor) agency, the employee must use all of the compensatory time off by the end of the 26th pay period following the pay period in which the employee returns to duty, or such compensatory time off will be forfeited:
(i) The employee separates or is placed in a leave without pay status to perform service in the uniformed services (as defined in 38 U.S.C. 4303 and 5 5 CFR 353.102) and later returns to service through the exercise of a reemployment right provided by law, Executive order, or regulation; or
(ii) The employee separates or is placed in a leave without pay status because of an on-the-job injury with entitlement to injury compensation under 5 U.S.C. chapter 81 and later recovers sufficiently to return to work.
(b)Upon transfer to another agency. When an employee voluntarily transfers to another agency (including a promotion or change to lower grade action), he or she must forfeit his or her unused compensatory time off.
(2) Unused compensatory time off will not be forfeited but will be held in abeyance in the case of an employee who separates from Federal service and later returns to service with the same (or successor) agency under the circumstances described in paragraph (a)(2) of this section.
(d)Upon movement to a noncovered position. When an employee moves to a Federal position not covered by this subpart, he or she forfeits any unused compensatory time off. This requirement does not prevent an agency from using another legal authority to give the employee credit for compensatory time off equal to the forfeited amount.
(e)Exception due to an exigency. If an employee fails to use his or her compensatory time earned under § 550.1404(a) by the end of the 26th pay period after the pay period during which it was earned due to an exigency of the service beyond the employee's control, an authorized agency official, at his or her sole and exclusive discretion, may extend the time limit for using such compensatory time off for travel for up to an additional 26 pay periods.
