5 C.F.R. Subpart C—Computation of Disability Annuity
Title 5 - Administrative Personnel
A disability annuity under this part commences on the day after the employee separates or the day after pay ceases and the employee meets the requirements for title to an annuity. (a) For the purposes of this subpart, the “adjusted social security disability benefit” is the benefit to which an annuitant is entitled under section 223 of the Social Security Act: (1) For the month in which the annuity under this part commences, or is reinstated under §844.405, or, if later, the first month for which the annuitant is entitled to both an annuity under this part and a social security disability benefit; (2) Including, where appropriate, a reduction under section 224 of the Social Security Act, based on the amount of the disability annuity under this subpart without regard to paragraphs (b)(2) and (c)(2) of this section; and (3) Adjusted by each cost-of-living increase effective under 5 U.S.C. 8462(b) beginning with the later of the month after the 12-month period referred to in paragraph (b)(1) of this section, or the first month for which the annuitant is entitled to both an annuity under this part and a social security disability benefit. (b)(1) Except as otherwise provided in this part, the annuity payable under this subpart until the end of the 12th month beginning after the annuity commences (or is reinstated under §844.405) is equal to 60 percent of the annuitant's average pay. (2) For months for which the annuitant is also entitled to a social security disability benefit, the amount computed under paragraph (b)(1) of this section is reduced by 100 percent of the annuitant's adjusted social security disability benefit. (c)(1) Except as otherwise provided in this part, the annuity under this subpart after the period described in paragraph (b)(1) of this section is equal to 40 percent of the annuitant's average pay. (2) For months after the period described in paragraph (b)(1) of this section for which the annuitant is also entitled to a social security disability benefit, the amount computed under paragraph (c)(1) of this section is reduced by 60 percent of the annuitant's adjusted social security disability benefit. (d) For months in which an annuity is reduced under paragraph (b) or (c) of this section, any reduction for survivor benefits is made after the reduction for social security benefits. Notwithstanding any other provision of this part, an annuity payable under this part cannot be less than the amount of an annuity computed under 5 U.S.C. 8415 (excluding subsection (f) of that section) based on the annuitant's service. (a) An individual retiring under this part is not entitled to elect to receive an alternative form of annuity under 5 U.S.C. 8420a, even if the individual meets the requirements for retirement under another part and would be entitled to elect an alternative form of annuity in connection therewith. (b) Notwithstanding any other provision of this part, an annuity payable under this part will be computed under 5 U.S.C. 8415 if it commences or is reinstated under §844.405 (b) or (c) of this part on or after: (1) The annuitant has satisfied the age and service requirements for retirement under 5 U.S.C. 8412 (a) through (f); or (2) The annuitant has reached age 62. Effective on and after the annuitant's 62nd birthday, the rate of annuity payable to a disability annuitant will be the amount of an annuity computed with respect to the annuitant under 5 U.S.C. 8415 (including subsection (g) of that section), including credit for all periods before the annuitant's 62nd birthday during which he or she was entitled to an annuity under this part. The average pay used in computing the annuity under 5 U.S.C. 8415 is adjusted by all cost-of-living increases effective under 5 U.S.C. 8462(b) during the period the annuitant was receiving the disability annuity under this part.
