Every political subdivision required to make payments is authorized in consideration of the employee's retention in, or entry upon, employment to impose upon each of its employees, as to services which are covered by the coverage agreement, a contribution with respect to wages computed by applying the rates of contribution prescribed by Subchapter A of the Federal Insurance Contributions Act, and to deduct the amount of such contribution from such employee's wages when paid.
Failure to deduct such contribution shall not relieve the employee or employer of liability therefor.
Coincident to the adoption of coverage, the governing body or board of trustees of the retirement system shall promulgate rules and regulations in conformity with federal regulations, applicable to the State or local governmental entities or to the agencies and employees participating therein, to insure the correct application of coverage and the timely and accurate reporting of wages and collection of contributions.
In the event of failure by the retirement system or the governmental entities or agencies participating therein to comply with the timely reporting and payment requirements imposed by this Section, the retirement system shall be assessed any federal interest or late filing penalties arising therefrom.
The contributions collected under this Section by any retirement system which elects to adopt coverage shall be remitted at such times as the State Agency shall prescribe.
The employees comprising the executive and administrative staff of any retirement system which elects to adopt the provisions of this Article shall have the contributions made by the body employing them.
