Reg. § 54.4980G-2 Employer contribution defined.

Q-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).
