Section 54.4980G-2 - Employer contribution definedQ-1: Do the comparability rules apply to amounts rolled over from an employee's HSA or Archer Medical Savings Account (Archer MSA)?A-1: No. The comparability rules do not apply to amounts rolled over from an employee's HSA or Archer MSA.Q-2: If an employee requests that his or her employer deduct after-tax amounts from the employee's compensation and forward these amounts as employee contributions to the employee's HSA, do the comparability rules apply to these amounts?A-2: No. Section 106(d) provides that amounts contributed by an employer to an eligible employee's HSA shall be treated as employer-provided coverage for medical expenses and are excludible from the employee's gross income up to the limit in section 223(b). After-tax employee contributions to an HSA are not subject to the comparability rules because they are not employer contributions under section 106(d).T.D. 9277, 71 FR 43058 , July 31, 2006
