(a) Claims. A claimant may at any time file a complaint under the child labor provisions of the Act or an FLSA claim challenging the correctness of his or her FLSA exemption status determination. A claimant may also file an FLSA claim concerning his or her entitlement to minimum wage or overtime pay for work performed under the Act; however, time limits apply to FLSA pay claims. All FLSA pay claims filed on or after June 30, 1994, are subject to a 2-year statute of limitations (3 years for willful violations).

(b) Statute of limitations. An FLSA pay claim filed on or after June 30, 1994, is subject to the statute of limitations contained in the Portal-to-Portal Act of 1947, as amended (section 255a of title 29, United States Code), which imposes a 2-year statute of limitations, except in cases of a willful violation where the statute of limitations is 3 years. In deciding a claim, a determination must be made as to whether the cause or basis of the claim was the result of a willful violation on the part of the agency.

(c) Preserving the claim period. A claimant or a claimant's designated representative may preserve the claim period by submitting a written claim either to the agency employing the claimant during the claim period or to OPM. The date the agency or OPM receives the claim is the date that determines the period of possible entitlement to back pay. The claimant is responsible for proving when the claim was received by the agency or OPM and for retaining documentation to establish when the claim was received by the agency or OPM, such as by filing the claim using certified, return receipt mail, or by requesting that the agency or OPM provide written acknowledgment of receipt of the claim. If a claim for back pay is established, the claimant will be entitled to pay for a period of up to 2 years (3 years for a willful violation) back from the date the claim was received.
