Sec. 4. (a) Every employee whose services are covered by the federal-state agreement or a modification of the agreement shall, as a condition of his employment, pay an amount equal to the employee tax imposed by the Federal Insurance Contributions Act.
(b) The employee's contribution shall be deducted from wages paid. Failure to make the deduction does not relieve the employee or the employer from liability for the contribution.
(c) Employees who are entitled to back coverage under the federal-state agreement shall make contributions for the back coverage. The employee may have the contribution deducted from his compensation or from the amount credited to his annuity savings account if he is a member of the public employees' retirement fund.
As added by Acts 1977, P.L.53, SEC.1. Amended by P.L.57-1987, SEC.3.
