Connecticut General Statutes Title 5. State Employees § 5-167. Contributions for prior years

(a) A former member who withdrew his retirement contributions and who is reemployed in state service within five years after he left state service, or who is reemployed and due to such reemployment is covered by the provisions of the tier I plan as determined under subsection (a) of section 5-192e, may elect to return his withdrawn contributions and interest paid on such contributions to the state, with interest as provided in subsection (c) of this section. Service can be restored only if payments commence within two years after reemployment or on or before January 1, 1985, if later.

(b) A member who was in state service before September 1, 1939, but did not become a member before September 1, 1941, may elect to make retirement contributions in the amount which would have been due from him from September 1, 1939, to the date of his election, had he been a member throughout this period, with interest as provided in subsection (c) of this section.

(c) Retirement contributions payable under subsection (a) or (b) of this section may be paid by the member either by (1) a single lump sum payment of contributions plus interest paid on such contributions, with interest thereon at the rate of five per cent per year calculated from the date of withdrawal to the date of payment, or (2) payroll deductions of the total amount established in subdivision (1) of this subsection, as determined by the Retirement Commission over a period not to exceed thirty-six months, plus interest on such amount at the rate of five per cent per year to be paid over such period.
