Yes, your S-Corp can pay for your health insurance premiums, but the tax treatment involves a specific process that many business owners get wrong. For greater-than-2% S-Corp shareholders, health insurance premiums paid by the corporation are not simply a tax-free fringe benefit like they would be for rank-and-file employees. Instead, the premiums follow a two-step process governed by IRS Notice 2008-1 and IRC Section 162(l) that ultimately results in an above-the-line deduction on your personal tax return.

The Two-Step Process

Step one: the S-Corp pays the health insurance premiums -- either directly to the insurance company or by reimbursing the shareholder for premiums paid personally. The S-Corp then includes the premium amount in the shareholder-employee's W-2 wages in Box 1 as taxable compensation. Critically, the premiums should not be included in Boxes 3 and 5 (Social Security and Medicare wages), which means they are not subject to FICA taxes. The S-Corp also deducts the premium payments as employee compensation expense under IRC Section 162.

Step two: the shareholder-employee claims the self-employed health insurance deduction on Line 17 of Schedule 1 (Form 1040) under IRC Section 162(l). This deduction reduces adjusted gross income dollar-for-dollar for the amount of health insurance premiums included in W-2 income. The net effect is that the premiums are deductible above the line, reducing AGI and all downstream calculations that depend on AGI -- including the net investment income tax threshold, the Medicare surtax threshold, and various phase-outs.

Requirements Under IRS Notice 2008-1

IRS Notice 2008-1 established three alternative methods for structuring the arrangement. Under the first method, the S-Corp establishes the health insurance plan in its own name and pays the premiums directly. Under the second method, the shareholder obtains insurance in their own name, and the S-Corp reimburses the premiums. Under the third method, the shareholder pays the premiums and the S-Corp includes the premium amount in the shareholder's W-2 without direct reimbursement. All three methods require that the health insurance plan be established in the name of the S-Corp or that the S-Corp either pay or reimburse the premiums during the calendar year.

The key requirement across all methods is that the premiums must be included in the shareholder's W-2 by the filing deadline of the S-Corp's employment tax returns (Form 941) for the applicable quarter. If the premiums are not properly reported on the W-2, the shareholder cannot claim the Section 162(l) deduction.

What Premiums Qualify

The Section 162(l) deduction covers health insurance premiums for the shareholder-employee, their spouse, their dependents, and any child under age 27 as of the end of the tax year. This includes medical insurance, dental insurance, vision insurance, and qualified long-term care insurance (subject to age-based limits under IRC Section 213(d)(10)). Medicare premiums -- including Part B, Part D, and Medigap policies -- also qualify if the shareholder is enrolled in Medicare.

Limitations on the Deduction

The Section 162(l) deduction cannot exceed the shareholder's earned income from the S-Corp for the year. If your W-2 wages from the S-Corp (excluding the health insurance add-back) are $50,000 and your health insurance premiums are $60,000, you can only deduct $50,000. The remaining $10,000 might be deductible as a medical expense on Schedule A if you itemize and your total medical expenses exceed 7.5% of AGI under IRC Section 213(a).

Additionally, the deduction is not available for any month in which you are eligible to participate in a subsidized health plan maintained by your spouse's employer -- even if you do not enroll. This frequently overlooked limitation can result in partial or full disallowance.

Common Errors to Avoid

The most common error is failing to include the premiums on the shareholder's W-2. If the S-Corp pays the premiums but does not add them to Box 1 of the W-2, the shareholder has received a tax-free benefit that is not authorized for greater-than-2% shareholders, and the Section 162(l) deduction is not available. Another frequent mistake is including the premiums in FICA wages (Boxes 3 and 5), which creates unnecessary payroll tax liability. The premiums should appear in Box 1 and Box 14 (with a notation such as "S-Corp Health Insurance") but not in Boxes 3 or 5.

A third error involves timing. The S-Corp must pay or reimburse the premiums during the tax year -- not after year-end. If premiums are paid in January for the prior year, they cannot be included on the prior year's W-2 and the deduction is lost for that year.

Properly structuring S-Corp health insurance requires coordination between payroll, tax reporting, and benefits administration. AE Tax Advisors ensures that S-Corp owners capture the full deduction while maintaining compliance with IRS Notice 2008-1 and avoiding costly payroll tax errors.
