Yes, your S corporation can pay for your health insurance, and it can do so whether the policy is in the company’s name or your own. The catch is that if you own more than 2 percent of the company, the IRS won’t let you take the coverage as a tax-free fringe benefit. Instead, the corporation pays or reimburses the premiums, adds that amount to your wages on Form W-2, and you claim a matching deduction on your personal return. Done correctly, the net tax result is favorable. Done sloppily, you lose the deduction and can trigger penalties on both sides.
Why the 2-Percent Rule Changes Everything
Federal tax law treats anyone who owns more than 2 percent of an S corporation’s stock, or more than 2 percent of its voting power, on any day of the tax year as a “2-percent shareholder.” For fringe benefit purposes, that person is treated like a partner in a partnership.1Office of the Law Revision Counsel. 26 USC 1372 – Partnership Rules To Apply for Fringe Benefit Purposes That single classification is what blocks tax-free health coverage and forces the wages-then-deduction route.
The threshold is easier to cross than it looks, because the IRS attributes stock owned by your spouse, children, grandchildren, and parents to you.2Office of the Law Revision Counsel. 26 USC 318 – Constructive Ownership of Stock Hold 1 percent yourself while your spouse holds 2 percent, and you’re a 3 percent owner in the IRS’s eyes. Siblings aren’t attributed, and there’s no chaining through one relative to reach an in-law. Because the test runs on any single day of the year, briefly crossing the line pulls you in for the whole year.
If you own 2 percent or less and take no attributed stock into account, none of what follows applies to you; you can receive health insurance as an ordinary tax-free employee benefit.
How the Corporation Pays the Premiums
The IRS accepts two payment methods, and either satisfies the requirement that the plan be “established” by the business.3IRS.gov. Notice 2008-1
- The S corporation pays the insurance carrier directly from its own account. This is the cleanest paper trail.
- You pay premiums personally, submit proof to the corporation, and the corporation reimburses you for the exact amount. The reimbursement has to happen in the same tax year the coverage applies to.
That same-year rule is firm. Pay a December premium yourself and get reimbursed in January, and the amount lands in the following tax year for reporting. On the books, label these transactions as health insurance reimbursements, not salary and not shareholder distributions, because each of those three categories has different tax consequences. The corporation deducts the premiums as a business expense, which reduces the taxable income that flows through to shareholders.4Internal Revenue Service.

What Coverage Qualifies
The arrangement isn’t limited to standard medical insurance. Any policy that constitutes “medical care” under the tax code works, including dental, vision, and qualified long-term care coverage. The policy can cover you, your spouse, your dependents, and any child of yours who hasn’t turned 27 by year end.5Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses – Section 162(l) Long-term care premiums carry age-based annual caps on the deductible amount.
What the W-2 Has To Show
The total annual premium goes into Box 1 of your Form W-2 as wages, and it’s subject to federal income tax withholding. If your state or locality has an income tax, the amount also belongs in Box 16 and Box 18.4Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues
The premiums are not subject to Social Security, Medicare, or federal unemployment tax, as long as the plan covers all employees or a class of employees and their dependents. So the amount should stay out of Box 3 (Social Security wages) and Box 5 (Medicare wages). Many preparers also note the premium in Box 14 with a label such as “S Corp Health Insurance.” Box 14 is informational, but it makes the personal return much easier to prepare.
Getting the boxes wrong hurts both ways. Omit the premium from Box 1 and you can’t claim the personal deduction. Include it in Boxes 3 and 5 and you and the corporation both overpay payroll taxes.
HSA Contributions
If the corporation puts money into a Health Savings Account for a 2-percent shareholder, those contributions do not get the tax-free treatment regular employees enjoy. The corporation includes the HSA contributions in the shareholder’s gross income in W-2 Box 1.6IRS.gov. Notice 2005-8 Like the insurance premiums, HSA contributions are generally exempt from Social Security, Medicare, and FUTA when the plan covers a class of employees. You then claim the HSA deduction on your personal return, but through a separate mechanism from the self-employed health insurance deduction.
Claiming the Deduction on Your Personal Return
Once the premium is sitting in Box 1 as wages, you recover it on Form 1040 as the self-employed health insurance deduction, an above-the-line adjustment that reduces adjusted gross income whether or not you itemize.5Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses – Section 162(l) The deduction goes on Schedule 1 (Form 1040), line 17. You calculate the allowable amount on Form 7206 and attach it to the return.7Internal Revenue Service. Instructions for Form 7206 (2025)
The Earned Income Cap
Your deduction cannot exceed the earned income you received from the S corporation that sponsors the plan. For a shareholder-employee, “earned income” here means wages under the Social Security tax definition, which corresponds to Box 5 (Medicare wages) rather than Box 1.8Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses – Section 162(l)(5) Form 7206, line 11 asks for exactly that figure.9IRS.gov. Form 7206
Say the corporation paid you $60,000 in salary and $12,000 in premiums. Box 1 shows $72,000, Box 5 shows $60,000, and the deduction limit is $60,000. The full $12,000 deducts easily. The cap only pinches when premiums start to approach the salary itself, which can happen in a small operation where the owner takes modest wages.
The Other-Employer Disqualification
You cannot take the deduction for any month you were eligible to participate in a subsidized health plan maintained by another employer. That includes a plan offered by your own second job, your spouse’s employer, or an employer of your dependent or qualifying child under 27.10Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses – Section 162(l)(2)(B) Eligibility alone triggers the rule. If your spouse’s employer offers family coverage during open enrollment and you’re eligible to join, those months are disqualified whether you actually enroll or not.
If You Can’t Take It All Above the Line
Any premium you can’t deduct on Schedule 1, because of the earned income cap or the other-employer rule, can be included as a medical expense on Schedule A if you itemize.7Internal Revenue Service. Instructions for Form 7206 (2025) Schedule A only picks up medical costs above 7.5 percent of AGI, so it’s less favorable, but not nothing. You cannot claim the same premium in both places.11Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses – Section 162(l)(3)
If You Also Get a Marketplace Premium Tax Credit
Shareholders who buy individual coverage through a Health Insurance Marketplace may also qualify for the premium tax credit, and the two figures interact in a loop: the self-employed health insurance deduction lowers your AGI, which can raise your allowable premium tax credit, which changes how much of the premium is deductible. The IRS lays out an iterative calculation for this in Publication 974.12Internal Revenue Service. Publication 974 (2025), Premium Tax Credit (PTC) Follow it precisely, or work with a preparer who has done it before. Missing the loop can mean either leaving money unclaimed or repaying excess credits at filing.
What Happens When the Reporting Is Wrong
If the corporation leaves the premium out of Box 1, your personal return will understate income, and the IRS can assess the accuracy-related penalty of 20 percent on the resulting underpayment.13Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments You also lose the ability to claim the self-employed health insurance deduction, because it depends on the premium being in wages to begin with.
The W-2 itself is due January 31 of the year after the tax year. Late or incorrect forms carry per-form penalties that scale with how late they are, and intentional disregard raises the ceiling further.14Internal Revenue Service.
