S-Corp Health Insurance: How to Report It Correctly on Your W-2 in NJ

January 12, 20265 min read

Health insurance premiums for S-Corp shareholders who own more than 2% of the company require special treatment. The premiums must be included on your W-2, but they’re also deductible on your personal return.

The Rule

The S-Corp includes the premium amount in the shareholder’s W-2 Box 1 as additional compensation. However, they are not subject to FICA taxes and should not be included in Boxes 3, 5, or 6. The shareholder then claims the self-employed health insurance deduction on Line 17 of Schedule 1.

Common Mistakes

The biggest mistake is not reporting the premiums on the W-2 at all. Another common error is including the premiums in FICA wages, which results in unnecessary payroll taxes. Some NJ S-Corp owners pay premiums personally and never run them through the business.

NJ State Treatment

New Jersey follows the federal treatment for health insurance premiums. The self-employed health insurance deduction flows through to your NJ-1040 the same way it does federally.

Bottom Line

If you have an S-Corp and you’re paying for your own health insurance, make sure the premiums are flowing through the company’s books and appearing on your W-2 correctly.
