Stop paying FICA on your premiums.

If you are an S-Corp owner (more than 2% shareholder), you have a unique way to deduct health insurance premiums. Instead of a standard business expense, these premiums are treated as wages — but with a twist: they are not subject to Social Security or Medicare (FICA) taxes.

By correctly reporting this on your W-2, you get a full deduction for the premiums on your 1040, reducing your taxable income while keeping your payroll taxes low.

The $12,000 Premium Example

Example — IRC §162(l)

Scenario: Your S-Corp pays $1,000/month for your family's health insurance.

  • Annual Premiums: $12,000
  • FICA Tax Savings (15.3%): $1,836
  • Personal Tax Deduction: $12,000 (IRC §162(l))
  • Total Tax Wealth Reclaimed: $6,276

Includes income tax savings and self-employment tax avoidance.

The "Established by the S-Corp" Rule

To qualify, the health insurance plan must be "established by the S-Corp":

  • The S-Corp must pay the premiums directly OR reimburse the owner for premiums they paid.
  • The premiums must be included in the owner's W-2 as taxable wages (Box 1).
  • Crucially, they are NOT included in Social Security or Medicare wages (Boxes 3 and 5).

Implementation Steps

  1. Company Payment: Set up your S-Corp to pay the health insurance provider directly.
  2. Payroll Update: Tell your payroll provider to add the health insurance amount to your W-2 Box 1 at year-end.
  3. 1040 Reporting: Claim the deduction on Schedule 1 of your Form 1040 as "Self-employed health insurance deduction."

Audit Protection

Critical Compliance

If you do not include the premiums on your W-2, you lose the deduction on your 1040. The IRS requires the W-2 Box 1 inclusion to verify the plan is established by the business. Work with your payroll provider and a licensed professional to ensure the year-end W-2 is set up correctly.
