Tenn. Code Ann. § 8-36-105: Lump sum payments by prior class members who limited earnable compensation

Any prior Class B member who limited such member's deduction to four thousand two hundred dollars ($4,200) of such member's annual salary may, upon proper authorization from the board of trustees, make a deposit in a lump sum equal to the amount which the member would have paid had the member been contributing on such member's annual salary, plus interest at the rate provided for in § 8-37-214 , relative to redeposits. Such an amount so deposited shall become a part of the member's accumulated contributions in the same manner as if the contributions had been timely paid.
