Q-1: If an employer makes contributions through a section 125 cafeteria plan to the HSA of each employee who is an eligible individual, are the contributions subject to the comparability rules?

A-1: (a) In general. No. The comparability rules do not apply to HSA contributions that an employer makes through a section 125 cafeteria plan. However, contributions to an HSA made through a cafeteria plan are subject to the section 125 nondiscrimination rules (eligibility rules, contributions and benefits tests and key employee concentration tests). See section 125(b), (c) and (g) and the regulations thereunder.

¶(b) Contributions made through a section 125 cafeteria plan. Employer contributions to employees' HSAs are made through a section 125 cafeteria plan and are subject to the section 125 cafeteria plan nondiscrimination rules and not the comparability rules if under the written cafeteria plan, the employees have the right to elect to receive cash or other taxable benefits in lieu of all or a portion of an HSA contribution (meaning that all or a portion of the HSA contributions are available as pre-tax salary reduction amounts), regardless of whether an employee actually elects to contribute any amount to the HSA by salary reduction.

Q-2: If an employer makes contributions through a cafeteria plan to the HSA of each employee who is an eligible individual in an amount equal to the amount of the employee's HSA contribution or a percentage of the amount of the employee's HSA contribution (matching contributions), are the contributions subject to the section 4980G comparability rules?

A-2: No. The comparability rules do not apply to HSA contributions that an employer makes through a section 125 cafeteria plan. Thus, where matching contributions are made by an employer through a cafeteria plan, the contributions are not subject to the comparability rules of section 4980G. However, contributions, including matching contributions, to an HSA made under a cafeteria plan are subject to the section 125 nondiscrimination rules (eligibility rules, contributions and benefits tests and key employee concentration tests). See Q & A-1 of this section.

Q-3: If under the employer's cafeteria plan, employees who are eligible individuals and who participate in health assessments, disease management programs or wellness programs receive an employer contribution to an HSA and the employees have the right to elect to make pre-tax salary reduction contributions to their HSAs, are the contributions subject to the comparability rules?

A-3: (a) In general. No. The comparability rules do not apply to employer contributions to an HSA made through a cafeteria plan. See Q & A-1 of this section.

(b) Examples. The following examples illustrate the rules in this § 54.4980G-5. The examples read as follows:

¶Example 1.

Employer A's written cafeteria plan permits employees to elect to make pre-tax salary reduction contributions to their HSAs. Employees making this election have the right to receive cash or other taxable benefits in lieu of their HSA pre-tax contribution. The section 125 cafeteria plan nondiscrimination rules and not the comparability rules apply because the HSA contributions are made through the cafeteria plan.

¶Example 2.

Employer B's written cafeteria plan permits employees to elect to make pre-tax salary reduction contributions to their HSAs. Employees making this election have the right to receive cash or other taxable benefits in lieu of their HSA pre-tax contribution. Employer B automatically contributes a non-elective matching contribution or seed money to the HSA of each employee who makes a pre-tax HSA contribution. The section 125 cafeteria plan nondiscrimination rules and not the comparability rules apply to Employer B's HSA contributions because the HSA contributions are made through the cafeteria plan.

¶Example 3.

Employer C's written cafeteria plan permits employees to elect to make pre-tax salary reduction contributions to their HSAs. Employees making this election have the right to receive cash or other taxable benefits in lieu of their HSA pre-tax contribution. Employer C makes a non-elective contribution to the HSAs of all employees who complete a health risk assessment and participate in Employer C's wellness program. Employees do not have the right to receive cash or other taxable benefits in lieu of Employer C's non-elective contribution. The section 125 cafeteria plan nondiscrimination rules and not the comparability rules apply to Employer C's HSA contributions because the HSA contributions are made through the cafeteria plan.

¶Example 4.

Employer D's written cafeteria plan permits employees to elect to make pre-tax salary reduction contributions to their HSAs. Employees making this election have the right to receive cash or other taxable benefits in lieu of their HSA pre-tax contribution. Employees participating in the plan who are eligible individuals receive automatic employer contributions to their HSAs. Employees make no election with respect to Employer D's contribution and do not have the right to receive cash or other taxable benefits in lieu of Employer D's contribution but are permitted to make their own pre-tax salary reduction contributions to fund their HSAs. The section 125 cafeteria plan nondiscrimination rules and not the comparability rules apply to Employer D's HSA contributions because the HSA contributions are made through the cafeteria plan.

Q-4: May all or part of the excise tax imposed under section 4980G be waived?

A-4: In the case of a failure which is due to reasonable cause and not to willful neglect, all or a portion of the excise tax imposed under section 4980G may be waived to the extent that the payment of the tax would be excessive relative to the failure involved. See sections 4980G(b) and 4980E(c).
