If you own more than 2 percent of an S corporation, you have to do three things to claim a deduction for your health insurance:
- You must get the cost of the insurance on the S corporation’s books.
- Your S corporation must include the health insurance premiums on your W-2 form.
- You must (if eligible) claim the health insurance deduction as an above-the-line deduction on Form 1040.
The three-step health-insurance procedure also applies under attribution rules (and this could be a surprise) to your spouse, children, grandchildren, and parents if they work for your S corporation, even if they don’t own a single share of S corporation stock directly.
You need to get this S corporation health-insurance thing right. Without the W-2 treatment, the S corporation does not get a tax deduction.
With the correct W-2 treatment, the more than 2 percent shareholder who finds the health insurance premiums on his or her W-2 can claim the self-employed health insurance deduction on Form 1040, provided he or she is not eligible for employer-subsidized health insurance through another job or a spouse’s job.
