year of coverage
(7) (A) In the case of an individual whose primary insurance amount would be computed under paragraph (1) of this subsection, who— (i) attains age 62 after 1985 (except where he or she became entitled to a disability insurance benefit before 1986 and remained so entitled in any of the 12 months immediately preceding his or her attainment of age 62), or (ii) would attain age 62 after 1985 and becomes eligible for a disability insurance benefit after 1985, and who first becomes eligible after 1985 for a monthly periodic payment (including a payment determined under subparagraph (C), but excluding (I) a payment under the Railroad Retirement Act of 1974 or 1937 [ 45 U.S.C. 231 et seq., 228a et seq.], (II) a payment by a social security system of a foreign country based on an agreement concluded between the United States and such foreign country pursuant to section 433 of this title , and (III) a payment based wholly on service as a member of a uniformed service (as defined in section 410(m) of this title )) which is based in whole or in part upon his or her earnings for service which did not constitute “employment” as defined in section 410 of this title for purposes of this subchapter (hereafter in this paragraph and in subsection (d)(3) referred to as “noncovered service”), the primary insurance amount of that individual during his or her concurrent entitlement to such monthly periodic payment and to old-age or disability insurance benefits shall be computed or recomputed under subparagraph (B). (B) (i) If paragraph (1) of this subsection would apply to such an individual (except for subparagraph (A) of this paragraph), there shall first be computed an amount equal to the individual’s primary insurance amount under paragraph (1) of this subsection, except that for purposes of such computation the percentage of the individual’s average indexed monthly earnings established by subparagraph (A)(i) of paragraph (1) shall be the percent specified in clause (ii). There shall then be computed (without regard to this paragraph) a second amount, which shall be equal to the individual’s primary insurance amount under paragraph (1) of this subsection, except that such second amount shall be reduced by an amount equal to one-half of the portion of the monthly periodic payment which is attributable to noncovered service performed after 1956 (with such attribution being based on the proportionate number of years of such noncovered service) and to which the individual is entitled (or is deemed to be entitled) for the initial month of his or her concurrent entitlement to such monthly periodic payment and old-age or disability insurance benefits. The individual’s primary insurance amount shall be the larger of the two amounts computed under this subparagraph (before the application of subsection (i)) and shall be deemed to be computed under paragraph (1) of this subsection for the purpose of applying other provisions of this subchapter. (ii) For purposes of clause (i), the percent specified in this clause is— (I) 80.0 percent with respect to individuals who become eligible (as defined in paragraph (3)(B)) for old-age insurance benefits (or became eligible as so defined for disability insurance benefits before attaining age 62) in 1986; (II) 70.0 percent with respect to individuals who so become eligible in 1987; (III) 60.0 percent with respect to individuals who so become eligible in 1988; (IV) 50.0 percent with respect to individuals who so become eligible in 1989; and (V) 40.0 percent with respect to individuals who so become eligible in 1990 or thereafter. (C) (i) Any periodic payment which otherwise meets the requirements of subparagraph (A), but which is paid on other than a monthly basis, shall be allocated on a basis equivalent to a monthly payment (as determined by the Commissioner of Social Security), and such equivalent monthly payment shall constitute a monthly periodic payment for purposes of this paragraph. (ii) In the case of an individual who has elected to receive a periodic payment that has been reduced so as to provide a survivor’s benefit to any other individual, the payment shall be deemed to be increased (for purposes of any computation under this paragraph or subsection (d)(3)) by the amount of such reduction. (iii) For purposes of this paragraph, the term “periodic payment” includes a payment payable in a lump sum if it is a commutation of, or a substitute for, periodic payments. (D) This paragraph shall not apply in the case of an individual who has 30 years or more of coverage. In the case of an individual who has more than 20 years of coverage but less than 30 years of coverage (as so defined), the percent specified in the applicable subdivision of subparagraph (B)(ii) shall (if such percent is smaller than the applicable percent specified in the following table) be deemed to be the applicable percent specified in the following table: If the number of such individual’s years of coverage (as so defined) is: The applicable percent is: 29 85 percent 28 80 percent 27 75 percent 26 70 percent 25 65 percent 24 60 percent 23 55 percent 22 50 percent 21 45 percent. For purposes of this subparagraph, the term “year of coverage” shall have the meaning provided in paragraph (1)(C)(ii), except that the reference to “15 percent” therein shall be deemed to be a reference to “25 percent”. (E) This paragraph shall not apply in the case of an individual whose eligibility for old-age or disability insurance benefits is based on an agreement concluded pursuant to section 433 of this title or an individual who on January 1, 1984 — (i) is an employee performing service to which social security coverage is extended on that date solely by reason of the amendments made by section 101 of the Social Security Amendments of 1983; or (ii) is an employee of a nonprofit organization which (on December 31, 1983 ) did not have in effect a waiver certificate under section 3121(k) of the Internal Revenue Code of 1954 and to the employees of which social security coverage is extended on that date solely by reason of the amendments made by section 102 of that Act, unless social security coverage had previously extended to service performed by such individual as an employee of that organization under a waiver certificate which was subsequently (prior to December 31, 1983 ) terminated.
