Section 105 HRA for S-Corp Owners: What Actually Works

A properly structured health reimbursement arrangement can allow an employer to reimburse eligible medical expenses and deduct the cost. The employee may exclude qualifying reimbursements from income. The result is valuable, but it is often oversold to S-corporation owners without explaining the special treatment of more-than-2% shareholders.

The central question is not whether Section 105 exists. It is whether the business has an eligible employee, whether the arrangement complies with health-plan rules, and whether ownership attribution prevents the reimbursement from being tax free to the recipient.

How a Section 105 Arrangement Works

The employer adopts a written plan that defines eligible employees, reimbursable medical expenses, substantiation procedures, limits, and timing. Employees submit proof of expenses, and the employer reimburses only qualifying costs. The business claims the deduction as an employee benefit rather than as an unsupported owner draw.

A plan is not a year-end journal entry. It requires a written document, consistent operation, receipts or other substantiation, and records showing that the reimbursement was actually paid. Expenses cannot be reimbursed twice or also claimed as an itemized medical deduction.

The More-Than-2% S-Corporation Problem

For many fringe-benefit rules, a more-than-2% S-corporation shareholder is treated similarly to a partner rather than a common-law employee. Medical reimbursements and health-insurance benefits generally must be included in the shareholder's Form W-2 wages, although they may qualify for the self-employed health-insurance deduction when the statutory requirements are satisfied.

Hiring the shareholder's spouse does not automatically solve the problem because family-attribution rules can cause the spouse to be treated as owning the shareholder's stock. Any plan marketed as producing tax-free medical reimbursements for an S-corporation owner's family should be reviewed specifically for Section 1372 and attribution before implementation.

Where the Strategy Can Fit

A C corporation can generally provide qualifying health benefits to employee-shareholders under the employee-benefit rules, subject to plan compliance. A sole proprietorship may sometimes use a bona fide employee-spouse arrangement, but employment must be real, compensation must be reasonable, and the health-plan rules still apply.

For an S corporation, the more common compliant route is to have the corporation pay or reimburse shareholder health-insurance premiums, include the amount properly on Form W-2, and evaluate the above-the-line self-employed health-insurance deduction. Other out-of-pocket medical costs do not become tax free merely because the corporation writes a reimbursement check.

Compliance Questions Before Adoption

Identify every employee and ownership relationship. Confirm whether the plan is an HRA, an excepted-benefit arrangement, or another group health plan. Coordinate with Affordable Care Act requirements, nondiscrimination rules, and the company's existing insurance. Define eligible expenses by reference to Section 213(d), establish substantiation, and use payroll reporting that matches the owner's tax status.

Red Flags

Be cautious when a proposal has no written plan, reimburses an owner with no eligible employee relationship, ignores S-corporation ownership attribution, treats every wellness purchase as medical care, or records one annual reimbursement without receipts. The deduction depends on the underlying expense and the legal status of the recipient, not the label placed on the payment.

Frequently Asked Questions

Can a 2% S-corp shareholder receive tax-free HRA reimbursements?

Generally, a more-than-2% S-corporation shareholder is not treated as a common-law employee for these fringe-benefit exclusions. Amounts often require special W-2 treatment rather than tax-free reimbursement.

Can the owner's spouse be the employee?

Sometimes a bona fide employee-spouse arrangement is relevant outside an S corporation, but S-corporation stock-attribution rules can cause the spouse to be treated as a shareholder. The entity and ownership facts must be reviewed.

Does the business need receipts?

Yes. The plan should require substantiation showing that each reimbursement is for an eligible medical expense and was not reimbursed elsewhere.
