S-Corp Medical Expense Reimbursement: W-2 Premiums for 2% Owners

For an owner holding more than 2% of an S-corporation, the S-corp medical expense reimbursement rules for owners come down to one workable path: the company pays or reimburses the owner’s health insurance premiums, adds that amount to the owner’s W-2 wages, and the owner then claims an above-the-line self-employed health insurance deduction on their personal return. Out-of-pocket medical costs and most tax-free reimbursement arrangements that work for regular employees do not work for these owners.¹

Who Counts as a 2% Owner

The special rules apply to any S-corp employee who owns more than 2% of the company’s outstanding stock, measured by voting power or share value, on any day of the tax year. Cross that line even for a single day and you’re treated like a partner rather than a regular employee for fringe benefit purposes.²

The threshold is easier to cross than many owners expect. Constructive ownership rules attribute stock held by your spouse, children, grandchildren, and parents to you. A shareholder with 1.5% directly becomes a greater-than-2% owner if a spouse holds another 1%. Stock in trusts, estates, and partnerships where the shareholder has a beneficial interest can also be attributed proportionately.³

The Only Path That Works: Premiums Through the W-2

The S-corp can deduct the health insurance premiums it pays on an owner’s behalf, but only if those premiums first flow through the owner’s W-2 as taxable wages. Skip that step and the IRS treats the arrangement as if no plan existed. Both the corporate deduction and the owner’s personal deduction disappear.⁴

Two payment routes work. The S-corp can pay the insurance company directly, or it can reimburse the owner who paid the premiums personally. If the policy is in the owner’s name, the reimbursement has to happen in the same tax year the owner paid the premium. An owner who pays out of pocket and never runs the expense through the company cannot claim the above-the-line deduction at all. The policy itself can be in either the S-corp’s name or the owner’s name; what matters is that the money ultimately comes from the S-corp and lands on the W-2.⁵

Exactly What Goes on the W-2

The premium amount belongs in Box 1 as part of gross wages, subject to income tax withholding. It should also appear in Box 14, labeled with something like “S-Corp Med Prem” or “SEHI,” which gives the owner clean documentation for the personal deduction.⁶

It does not belong in Boxes 3 or 5. When premiums are paid under a plan covering employees and their dependents, the premium amount is not subject to Social Security, Medicare, or FUTA taxes. Adding it to Boxes 3 and 5 creates unnecessary payroll tax on both sides.¹

On the corporate return, the premium gets bundled into officer compensation on Line 7 or salaries and wages on Line 8 of Form 1120-S. The 1120-S instructions specifically direct that fringe benefit expenditures for greater-than-2% shareholders go on those lines, not on the employee fringe benefit line.⁶

How the Owner Claims the Deduction

With the premium properly included in Box 1, the owner reports the full wage amount as income on Form 1040 and then claims the self-employed health insurance deduction on Schedule 1, Line 17. This is above the line, so it reduces adjusted gross income directly and doesn’t require itemizing. Many owners can calculate it from the Form 1040 worksheet, but those with multiple self-employment sources, long-term care premiums, or Form 2555 filings must use Form 7206.⁷

Premium dollars taken as the above-the-line deduction can’t also be counted toward itemized medical expenses on Schedule A. One path or the other.⁸

Two Limits That Can Erase the Deduction

Even flawless W-2 reporting can be undone by two statutory limits in Section 162(l).

The other-coverage rule. The deduction is unavailable for any month the owner or the owner’s spouse is eligible to participate in a subsidized health plan maintained by any employer. Enrollment doesn’t matter. If a spouse’s job offers subsidized group coverage the owner’s household could join, those months are out. This catches people most often when a spouse changes jobs mid-year.⁹

The earned income limit. The deduction cannot exceed the owner’s W-2 wages from the S-corp. An owner paid $30,000 in wages who pays $36,000 in premiums can deduct only $30,000. This backfires on owners who deliberately keep salary low to minimize payroll taxes; drop below the annual premium cost and the excess is nondeductible.¹⁰

Which Premiums Qualify

The W-2 route works for medical, dental, and vision insurance, plus qualified long-term care coverage. It also covers the owner’s spouse, dependents, and children under age 27 even if they aren’t dependents.¹¹

Medicare Premiums

Owners 65 and older can run Medicare Part B, Part D, and Medigap premiums through the same W-2 inclusion process. The IRS confirms in the Form 7206 instructions that voluntarily paid Medicare premiums in your name qualify for the self-employed health insurance deduction. The S-corp reimburses, reports on the W-2, and the owner deducts. Owners who treat Medicare as a purely personal expense routinely leave this deduction on the table.⁵

Long-Term Care Insurance Caps

Qualified long-term care premiums qualify, but with age-based annual limits per person. For 2026:

Age 40 or younger: $500
Age 41 to 50: $930
Age 51 to 60: $1,860
Age 61 to 70: $4,960
Over age 70: $6,200

Amounts above these caps can’t be included in the above-the-line deduction, though they may still count as itemized medical expenses on Schedule A if the owner clears the 7.5%-of-AGI floor.¹²

Out-of-Pocket Medical Costs Don’t Qualify

The above-the-line route is for premiums only. Deductibles, copays, prescriptions, and medical equipment don’t qualify, and the S-corp cannot reimburse those costs to a 2% owner tax-free. The only route for out-of-pocket costs is the Schedule A itemized medical expense deduction, which helps only when total medical costs exceed 7.5% of AGI and the owner’s itemized deductions beat the standard deduction.¹³

HRAs, ICHRAs, and HSAs Do Not Work Tax-Free

Several reimbursement arrangements that work cleanly for regular employees fall apart for greater-than-2% owners, because Section 1372 treats these owners as partners rather than employees.²

Any reimbursement from a standard Health Reimbursement Arrangement to a 2% owner is taxable income. Individual Coverage HRAs (ICHRAs) follow the same logic.
The S-corp cannot make tax-free contributions to a 2% owner’s Health Savings Account. Employer contributions become taxable W-2 wages. The owner can still make personal, tax-deductible HSA contributions through an eligible high-deductible plan, but not on a pretax basis through the company.

Trying to funnel tax-free medical benefits to a 2% owner through these arrangements can trigger the excise tax under Section 4980D: $100 per day per affected individual, or $36,500 per year per owner. That penalty can dwarf any tax benefit the arrangement was reaching for.¹⁴

The Single-Employee Exception

There is one narrow carve-out. The Section 4980D excise tax generally doesn’t apply when only one current employee participates in the reimbursement arrangement. If the S-corp’s only employees are the owner and family members covered under one family plan, the IRS treats that as a single-participant arrangement exempt from the ACA market reform rules. The W-2 inclusion requirement still applies to any premiums. The moment the company hires a non-family employee who participates, the exception is gone.¹

Mistakes That Cost Owners the Deduction

A handful of errors come up again and again:

Paying the premium through the S-corp but never adding it to the W-2. Both sides lose the deduction, and the IRS is unforgiving on this one.
Putting the premium in Boxes 3 and 5, creating payroll tax that shouldn’t apply.¹
Omitting the Box 14 notation. Preparers who see wages in Box 1 with no breakdown often miss the deduction entirely.
Overlooking a spouse’s eligibility for subsidized group coverage, which kills the deduction for those months.⁹
Setting W-2 wages below the annual premium cost, so the earned income limit strands part of the deduction.
Reimbursing the owner informally with no paper trail. Notice 2008-1 requires the S-corp to actually pay or reimburse the premium.⁴

The flow is simple when every step connects: the S-corp pays or reimburses the premium, reports it in Box 1 and Box 14 (not Boxes 3 and 5), deducts it as compensation on Form 1120-S, and the owner claims the above-the-line deduction on Schedule 1. Skip any step and the chain breaks for everyone.
