How does health insurance work for S-corporation owners?
An S-corporation shareholder-employee who owns more than 2% of stock has the company pay or reimburse the ACA-compliant private health premium, include the amount in the shareholder's W-2 Box 1 wages, and the shareholder then deducts it as a self-employed health insurance deduction on Form 1040 (IRS Notice 2008-1).

What it means
- The premium is not subject to FICA when reported this way.
- The plan must be established in the name of the S-corp or reimbursed under a compliant arrangement.
Action steps
- Have payroll add the annual premium to Box 1 wages by year-end.
- Give your CPA the 1095 and payroll detail so the self-employed health insurance deduction is calculated correctly.
Risks & deadlines
- Missing the W-2 inclusion breaks the deduction chain and can trigger IRS correction notices.
