Health Insurance Deductions for S Corporation Owners

As a small business owner operating an S corporation, you can optimize your health insurance deductions. This guide explains how to take full advantage of these deductions and avoid penalties.

Steps to Ensure Your Health Insurance Deductions

Here's how you, as a more than 2% shareholder-employee, can deduct your health insurance premiums:

1. Establishing the Health Insurance Plan:

    • The S corporation directly pays the premiums for your accident and health insurance policy (covering you, your spouse, and dependents if applicable).
    • Alternatively, you pay the premiums and provide proof of payment to the S corporation, which then reimburses you.

2. Reporting on W-2:

The S corporation includes the health insurance premiums as wages on your W-2 form. However, these are not subject to Social Security and Medicare taxes. This means the premiums are reported in Box 1, not Boxes 3 or 5.

3. Claiming the Deduction:

You claim the health insurance deduction on Form 1040, Schedule 1 (line 16 as of 2024), provided you meet the eligibility criteria.

Important Considerations

1. Other Employer-Sponsored Insurance:

You cannot take this deduction if you or your spouse is eligible for employer-subsidized health insurance, even if you don't use it.

2. Salary Limitation:

Your insurance premium deduction cannot exceed your salary from the S corporation.


  • Scenario 1: You pay your insurance premiums without reimbursement from your S corporation. You are not entitled to the self-employed health insurance deduction.
  • Scenario 2: Your S corporation reimburses you for the premiums you paid and reports it as wages on your W-2. You can deduct these premiums as self-employed health insurance.

Group Insurance and Discrimination

If your S corporation provides group health insurance, you must treat your own benefits differently:

  • Employees: The S corporation deducts its contributions, and employees receive the benefits tax-free.
  • Owner-Employees: Follow the three-step process (establish the plan, report on W-2, claim the deduction).

Currently, the IRS does not enforce nondiscrimination provisions, allowing you to tailor health insurance benefits to different groups within your company.

Key Points (as of 2024)

To qualify for the self-employed health insurance deduction, ensure:

  1. Your S corporation pays or reimburses your insurance premiums.
  2. The premiums are included as wages on your W-2.
  3. You deduct the premiums on Schedule 1 of your Form 1040.
