20 CFR § 404.468 - Nonpayment of benefits to prisoners.
(a)General. No monthly benefits will be paid to any individual for any month any part of which the individual is confined in a jail, prison, or other penal institution or correctional facility for conviction of a felony. This rule applies to disability benefits (§ 404.315) and child's benefits based on disability (§ 404.350) effective with benefits payable for months beginning on or after October 1, 1980. For all other monthly benefits, this rule is effective with benefits payable for months beginning on or after May 1, 1983. However, it applies only to the prisoner; benefit payments to any other person who is entitled on the basis of the prisoner's wages and self-employment income are payable as though the prisoner were receiving benefits.
(b)Felonious offenses. An offense will be considered a felony if -
(1) It is a felony under applicable law: or
(2) In a jurisdiction which does not classify any crime as a felony, it is an offense punishable by death or imprisonment for a term exceeding one year.
(c)Confinement. In general, a jail, prison, or other penal institution or correctional facility is a facility which is under the control and jurisdiction of the agency in charge of the penal system or in which convicted criminals can be incarcerated. Confinement in such a facility continues as long as the individual is under a sentence of confinement and has not been released due to parole or pardon. An individual is considered confined even though he or she is temporarily or intermittently outside of that facility (e.g., on work release, attending school, or hospitalized).
(d)Vocational rehabilitation exception. The nonpayment provision of paragraph (a) of this section does not apply if a prisoner who is entitled to benefits on the basis of disability is actively and satisfactorily participating in a rehabilitation program which has been specifically approved for the individual by court of law. In addition, the Commissioner must determine that the program is expected to result in the individual being able to do substantial gainful activity upon release and within a reasonable time. No benefits will be paid to the prisoner for any month prior to the approval of the program.
