How to Report Health Insurance on W-2s for S-Corp Owners
One of the most common mistakes generalist accountants make is failing to correctly report health insurance premiums for 2% (or greater) shareholders. If this isn't handled correctly on your W-2, you could lose the ability to deduct those premiums on your personal return.
The Rules for 2026
To claim the Self-Employed Health Insurance Deduction (an "above-the-line" deduction on Form 1040), the following must happen:
1. Company Paid: The S-Corp must pay the premiums directly or reimburse the shareholder (with proof of payment).
2. Reported as Wages: The amount of the premiums must be included in Box 1 (Federal Wages) on the shareholder's W-2.
3. Excluded from FICA: Generally, these premiums are not subject to Social Security or Medicare taxes if the plan is set up correctly.
