(a) Any member who left the employ of an employer participating in the Tennessee consolidated retirement system in order to perform military service in the armed forces of the United States, and who is reemployed by such employer within six (6) months of honorable discharge from such service, shall have the option of establishing retirement credit for the military service under the following conditions:

(1) The member must be entitled to reemployment with the employer pursuant to the Uniformed Services Employment and Reemployment Rights Act (38 U.S.C. §§ 4301-4334);

(2) The member must not be able to establish the military service in any other retirement system; provided, that this subdivision (a)(2) shall not apply to the extent it is preempted by federal law;

(3) The member must redeposit any amount the member withdrew from the retirement system upon leaving the employ of such employer, plus interest at the rate provided in § 8-37-214(a); and

(4) The member must make a back payment equal to the amount of employee contributions the member would have made had the member remained continuously employed with the employer during the period of military service claimed. Such contributions shall be based upon the earnable compensation the member was earning at the time the member left employment to enter the military. Notwithstanding anything in this subdivision (a)(4) to the contrary, if the military service was during the Persian Gulf War, the service shall be credited without charge to the member, unless the member is an employee of a political subdivision. If the member is an employee of a political subdivision, the service shall be credited without charge to the member; provided, that the political subdivision accepts the liability therefor. “Persian Gulf War” means the period from and including August 2, 1990, to the date thereafter prescribed by presidential proclamation or by federal law.

(1) Any member or retired member who served in the armed forces of the United States during any period of armed conflict, as defined in subdivision (b)(2), shall be entitled to establish retirement credit for such military service without charge under the following conditions:

(A) The member was honorably discharged from such military service;

(B) The member cannot establish the military service in any other retirement system; provided, that this subdivision (b)(1)(B) shall not apply to the extent it is preempted by federal law; and

(C) The military service credit cannot be used in determining any rights under the retirement system prior to the member becoming vested.

(2) “Period of armed conflict” means:

(c) Any member or retired member who performed peacetime military service in the armed forces of the United States at any time from October 15, 1940, through May 7, 1975, shall be entitled to establish retirement credit for that military service under the following conditions:

(1) For the member's first year of peacetime military service, the credit shall be on the basis of one (1) day of creditable service for each day of military service rendered. To establish the first year of such military service, the member must pay employee contributions for the service claimed based on a contribution rate of ten and one half percent (10½%). The rate shall be applied to the member's earnable compensation at the time of the claim or, if not in service at the time of the claim, the member's earnable compensation at termination of employment;

(2) After the first year of peacetime military service, the credit shall be on the basis of one (1) day of creditable service for each two (2) days of military service rendered. To establish such military service, the member must pay employee contributions for the service claimed based on a contribution rate of nine percent (9%). The rate shall be applied to the member's earnable compensation at the time of the claim or, if not in service at the time of the claim, the member's earnable compensation at termination of employment; and

(3) The member shall be subject to the conditions set forth in subdivisions (b)(1)(A)-(C).

(d) Any member who was honorably discharged as a result of one hundred percent (100%) permanent total disability from any service-connected, combat-related cause as determined by the United States veterans administration whose permanent total disability existed on the date of discharge shall not be deemed to have military credit in any other retirement system, unless the member retired from the military with twenty (20) or more years of service.

(e) Subsections (b)-(d) shall be optional to political subdivisions in accordance with § 8-35-217.

(f) For part-time members, earnable compensation shall be increased to the corresponding full-time earnable compensation.

(i) Effective with respect to deaths occurring on or after January 1, 2007, while a member is performing qualified military service, as defined in the Uniformed Services Employment and Reemployment Rights Act of 1994 (38 U.S.C. §§ 4301 et seq.), to the extent required by § 401(a)(37) of the Internal Revenue Code (26 U.S.C. § 401(a)(37)), survivors of a member in a state or local retirement or pension system, are entitled to any additional benefits that the system would provide if the member had resumed employment and then died, such as accelerated vesting or survivor benefits that are contingent on the member's death while employed. In any event, a deceased member's period of qualified military service must be counted for vesting purposes.

(j) Beginning January 1, 2009, to the extent required by § 414(u)(12) of the Internal Revenue Code (26 U.S.C. § 414(u)(12)), an individual receiving differential wage payments, as defined under 26 U.S.C. § 3401(h)(2), from an employer shall be treated as compensation for purposes of applying the limits on annual additions under § 415(c) of the Internal Revenue Code (26 U.S.C. § 415(c)). This subsection (j) shall be applied to all similarly situated individuals in a reasonably equivalent manner.
