20 CFR §10.18

1. (a)Whenever a beneficiary is incarcerated in a State or Federal jail, prison, penal institution or other correctional facility due to a State or Federal felony conviction, he or she forfeits all rights to compensation benefits during the period of incarceration. A beneficiary's right to compensation benefits for the period of his or her incarceration is not restored after such incarceration ends, even though payment of compensation benefits may resume. A beneficiary has an affirmative duty to provide notice of any conviction and imprisonment. The employing agency shall provide OWCP any information or documentation they may have concerning such matters.
2. (b)If the beneficiary has eligible dependents, OWCP will pay compensation to such dependents at a reduced rate during the period of his or her incarceration, by applying the percentages of 5 U.S.C. 8133(a)(1) through (5) to the beneficiary's gross current entitlement rather than to the beneficiary's monthly pay.
3. (c)If OWCP's decision on entitlement is pending when the period of incarceration begins, and compensation is due for a period of time prior to such incarceration, payment for that period will only be made to the beneficiary following his or her release.
