Montana Title 19. Public Retirement Systems § 19-1-702. Contributions by state employees

(1) Every employee of the state whose services are covered by an agreement entered into under 19-1-401 and 19-1-402 must be required to pay, for the period of coverage, contributions with respect to wages equal to the amount of employee tax that would be imposed by the Federal Insurance Contributions Act if the services constituted employment within the meaning of that act. The liability arises in consideration of the employee's retention in the service of the state or entry into service.

(2) The contribution imposed by this section must be collected by deducting the amount of the contribution from wages paid, but failure to make the deduction does not relieve the employee from liability for the contribution.

(3) If more or less than the correct amount of the contribution imposed by this section is paid or deducted with respect to any remuneration, proper adjustments or a refund if adjustment is impracticable must be made, without interest, in the manner and at times that the department prescribes.
