Colorado Revised Statutes Title 24. Government State § 24-53-103. Employee contribution

(1) Every employee of the political subdivision whose services are covered by an agreement entered into pursuant to the provisions of section 24-53-102 shall be required to pay for the period of such coverage into the contribution fund, established pursuant to the provisions of section 24-53-105, contributions with respect to wages, as defined in section 24-53-101, equal to the amount of tax which would be imposed by the federal insurance contributions act if such services constituted employment within the meaning of that act. Such liability shall arise in consideration of the retention of the employee in the service of the political subdivision, or his entry upon such service, after July 1, 1987.

(2) The contribution imposed by the provisions of this section shall be collected by deducting the amount of the contribution from wages as and when paid, but failure to make such deduction shall not relieve the employee from liability for such contribution.

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