Is S-Corp Owner Health Insurance Part of Reasonable Comp? (w/Examples) + FAQs

This article reflects federal rules as of June 2026 and covers tax years 2025 and 2026. State rules vary and are covered in general terms below. Tax law changes often — confirm current figures with the IRS or a licensed professional before you file.

Quick Answer

No. For tax years 2025 and 2026, health insurance premiums an S corporation pays for a more-than-2% shareholder do not count toward reasonable compensation. They sit in W-2 Box 1 (income tax wages) but are excluded from Box 3 and Box 5 (Social Security and Medicare wages), and reasonable comp is measured by Medicare wages.

This trips up thousands of owners every year. Your health premiums increase the income shown on your W-2, so it feels like they should count toward the “reasonable salary” the IRS demands before you take distributions. They do not. The IRS and the courts measure your reasonable compensation against the FICA-taxable wages in Box 5 — and health insurance is deliberately carved out of that box, so leaning on it leaves your salary short.

This matters because a salary that looks fine on paper can still be too low once you strip the premiums back out. The IRS reported that S corporations are the most common business entity filing a return, and reasonable compensation remains one of its top examination targets — an audit can reclassify your distributions as wages, add back payroll tax, and pile on penalties and interest.

The Core Question, Deconstructed

This topic lives where two separate IRS rules collide, and most confusion comes from treating them as one rule. The first rule is reasonable compensation — an S-corp shareholder who works in the business must be paid a fair wage as a W-2 employee before taking tax-favored distributions. The second rule is the more-than-2% shareholder health insurance rule — special tax treatment for the medical premiums the company pays on that owner’s behalf.

A “2% shareholder” means anyone who owns more than 2% of the S corporation’s stock or voting power on any day of the year, as defined under Section 1372 of the tax code. Family attribution rules apply, so a spouse, child, parent, or grandparent who owns stock can pull you over the line. If you own 100% of your S-corp, you are squarely in this group.

Here is the key fact that answers the whole question. When the company pays your health premiums, that amount is added to Box 1 of your W-2 as income-taxable wages, but it is specifically excluded from Box 3 and Box 5, your Social Security and Medicare wages, and it is not subject to FICA tax, per longstanding IRS guidance. Reasonable compensation, meanwhile, is judged against the FICA-taxable wage figure — the Box 5 Medicare wages. Because premiums are stripped out of Box 5, they cannot count toward your reasonable comp.

What “reasonable compensation” actually measures

Reasonable compensation is the wage a business would pay an unrelated person to perform the same services you perform for your S-corp. The IRS instructs that officers who provide more than minor services and receive payment are employees, and their pay is wages subject to employment taxes. The standard is “what would you have to pay someone else to do your job?”

The consequence of getting this wrong is direct: if your wage is too low and you took distributions, the IRS can reclassify those distributions as wages. That reclassification triggers back Social Security and Medicare tax (15.3% on the reclassified amount up to the wage base), plus failure-to-deposit penalties and interest. The fix is to set the number against real market data for all the duties you perform — not against a figure padded by benefits.

Why health insurance is carved out of FICA wages

The carve-out is a feature, not an accident. Under Notice 2008-1, which taxpayers may still rely on because the IRS has issued no replacement, premiums the S-corp pays for a 2% shareholder are income to the shareholder but are not treated as FICA wages. This is what lets you avoid the 15.3% payroll tax on the premium dollars.

That same exclusion is exactly why those dollars cannot prop up your reasonable salary. The whole point of reasonable comp is to capture the wages that should bear FICA tax. Dollars that escape FICA by design cannot also satisfy a test built on FICA-taxable wages — you cannot have it both ways. The misconception that “my W-2 shows $80,000, so I’m fine” fails the moment an examiner looks at Box 5 instead of Box 1.

Which Situation Applies to You?

The answer to “does my health insurance count?” is always no, but what you should do next depends on your facts. Use this to find your path.

You own 100% and are the only worker: You set your own reasonable comp. Make sure the Box 5 figure — not Box 1 — clears your market wage. Skip to the worked example.
You and your spouse both own stock and work in the business: Family attribution makes you both 2% shareholders. Each working owner needs a reasonable wage; read the named examples.
You took distributions but a low or zero salary: You are in the highest-risk group. Read the Watson and Glass Blocks sections now.
The company reimburses you for a policy in your own name: This works only if reported correctly on the W-2; see the reporting section.
Your S-corp had a loss but you still took money out: Distributions, not profit, trigger reasonable comp. Read Glass Blocks.

The Worked Example: How Premiums Mask an Underpaid Salary

This is the math the IRS will do, so do it first. Meet Dana, a sole owner of a marketing S-corp for tax year 2025. Her books show $150,000 of net profit before her pay. She decides her “salary” is $60,000, and the company pays $18,000 a year for her family health plan.

Here is how it looks on her W-2 and why it fails.

W-2 Box 1 (income wages): $60,000 cash salary + $18,000 premiums = $78,000
W-2 Box 5 (Medicare wages): $60,000 cash salary only = $60,000
Premiums are excluded from Box 5 per Notice 2008-1

Dana sees $78,000 and feels safe. But suppose market data shows a marketing director with her duties earns $85,000. The IRS measures her reasonable comp against Box 5 = $60,000, not Box 1 = $78,000. Her salary is short by $25,000, and she took roughly $72,000 in distributions, so the shortfall is fully exposed.

If an examiner reclassifies $25,000 of distributions as wages, the added FICA tax is 15.3% × $25,000 = $3,825, before failure-to-deposit penalties (which can reach 10%) and interest. Had Dana set her cash salary at $85,000 from the start, her Box 5 would clear the bar and the $18,000 in premiums would still save her about $2,754 (15.3% × $18,000) in payroll tax — legitimately. The premiums are a bonus, not a building block.

Reporting the Premiums Correctly

Doing this right is what creates the paper trail the IRS likes and unlocks your personal deduction. Each step matters, and skipping one breaks the chain.

The S-corp must either pay the premiums directly or reimburse the shareholder for a policy, and then report the total as wages in Box 1 of the Form W-2, per Notice 2008-1. Many payroll systems also note the amount in Box 14 labeled something like “2% SH MED.” The premiums are excluded from Boxes 3 and 5, and no FICA is withheld on them.

On the business return, the S-corp deducts the premiums. They flow into the officer compensation or employee benefit lines of Form 1120-S as a wage expense, so the company gets a full deduction. The shareholder then takes the self-employed health insurance deduction above the line on Schedule 1 of the Form 1040, removing the premiums from income tax.

The result nets out beautifully: the premiums add to income on the W-2, then come right back off on Schedule 1, so they cost zero income tax — and they never bore FICA tax in the first place. But the deduction is lost entirely if the premiums are not reported on the W-2, the single most common error here.

Direct payment vs. reimbursement

The company can pay the insurer directly, or you can pay a policy in your own name and have the company reimburse you. Both qualify under Notice 2008-1 as a plan “established by the S corporation,” as long as the reimbursement is reported as wages on the W-2.

What does not work is paying for the policy yourself, telling no one, and claiming the deduction. If the S-corp never reports the premiums on your W-2, the IRS position is that you get no self-employed health insurance deduction at all. The consequence is real money: an owner with $18,000 of premiums and a 24% bracket loses about $4,320 of federal income tax savings by skipping the W-2 step.

The earned-income limit

Your self-employed health insurance deduction cannot exceed your earned income from the S-corp. The rule requires that your Medicare wages from the company exceed the cost of the premiums.

If you pay yourself a tiny salary, you can cap your own deduction. An owner with a $10,000 salary and $18,000 of premiums cannot deduct the full $18,000 — another reason a too-low salary backfires. Set the cash wage high enough to support both the reasonable-comp standard and the full premium deduction.

What the Courts Say

Two cases define how aggressively the IRS pursues low salaries, and neither lets benefits fill the gap.

In David E. Watson, P.C. v. United States, 668 F.3d 1008 (8th Cir. 2012), an accountant paid himself a $24,000 salary while taking about $204,000 in distributions. The court upheld the IRS expert’s reasonable comp figure of $91,044, and the difference was reclassified as wages subject to FICA. The case confirmed the IRS can recast distributions as wages when the salary is unreasonably low for the services performed.

In Glass Blocks Unlimited v. Commissioner, T.C. Memo. 2013-180, the sole owner took no salary but pulled money out of a barely profitable company. The Tax Court reclassified about $30,000 per year of those transfers as wages, holding that reasonable compensation is triggered by distributions, not profit — an S-corp can even post a loss after the assessment and still owe payroll tax.

The lesson for our question is blunt: in both cases the court looked at the FICA-taxable cash wage, not at fringe benefits. Health premiums would not have saved either owner because premiums are not FICA wages. As RCReports notes, reasonable compensation figures include taxable Medicare wages but specifically exclude non-taxable fringe benefits such as health insurance.

Three Common Scenarios

Scenario 1 — The owner who counts premiums as salary

What Dana Does	What the IRS Does
Pays $60,000 cash + $18,000 premiums, calls it $78,000 salary	Measures Box 5 = $60,000 against an $85,000 market wage
Takes $72,000 in distributions, feels protected	Reclassifies $25,000 of distributions as wages, adds $3,825 FICA plus penalties

Scenario 2 — The owner who pays premiums personally and stays quiet

What Marcus Does	What the IRS Does
Pays his own policy, never reports it on the W-2	Disallows the self-employed health insurance deduction entirely
Claims $18,000 on Schedule 1 anyway	Removes the deduction; in a 24% bracket that is $4,320 of tax back due, plus interest

Scenario 3 — The owner who sets salary correctly

What Priya Does	What the IRS Does
Pays $85,000 cash (clears market), $18,000 premiums on top, all on the W-2	Accepts Box 5 = $85,000 as reasonable; no reclassification
Deducts $18,000 on Schedule 1	Allows the deduction; premiums save 15.3% FICA legitimately

Named Examples

Dana, marketing S-corp owner. Dana’s goal is to minimize payroll tax. By treating $18,000 of premiums as part of a $78,000 “salary,” she leaves her real FICA wage at $60,000 — $25,000 below market. Her shortcut creates exactly the exposure Watson punished. The fix: raise cash salary to market, keep premiums as a separate, legitimate FICA-free benefit.

Marcus, freelance consultant S-corp. Marcus pays his ACA marketplace policy from his personal account and never tells his payroll provider. He claims the $18,000 deduction on Schedule 1. Because the premiums never hit his W-2, the IRS disallows the deduction. Marcus should have the company reimburse him and report the amount as Box 1 wages.

Priya, design-firm owner. Priya sets her cash salary at $85,000 using market data for a creative director, then adds $18,000 of company-paid premiums on top, all reported on the W-2. Her Box 5 clears the reasonable-comp bar, her premiums escape FICA, and her Schedule 1 deduction is fully allowed. She is the model.

Mistakes to Avoid

Counting premiums toward reasonable comp. Premiums sit in Box 1, not Box 5; the IRS measures comp by Box 5, so your salary is really lower than it looks — and reclassification follows.
Paying yourself zero salary while taking distributions. Glass Blocks shows the IRS will reclassify distributions as wages even in a loss year, adding FICA, penalties, and interest.
Failing to report premiums on the W-2. This single omission destroys your self-employed health insurance deduction, costing thousands in lost income tax savings.
Withholding FICA on the premiums. Premiums are not FICA wages; withholding Social Security and Medicare on them overpays tax and signals a misconfigured payroll setup.
Setting salary below your premium cost. Your deduction cannot exceed your earned income, so a tiny salary caps the very deduction you wanted.
Ignoring family attribution. A spouse’s or child’s stock can make you a 2% shareholder, changing how all your benefits are taxed.
Treating shareholder loans loosely. As in Glass Blocks, undocumented “loans” out of the company get recast as distributions and trigger reasonable comp.
Using last year’s market figure forever. Reasonable comp should reflect current market wages for all duties you perform; a stale number invites challenge.

Do’s and Don’ts

Do:

Do measure your salary against Box 5 Medicare wages, because that is the number the IRS tests.
Do report all 2% shareholder premiums on the W-2, since reporting is what unlocks the deduction.
Do document how you chose your salary with market data, because the burden of proof is on you.
Do keep cash salary above your premium cost, so your full self-employed health deduction survives.
Do consult a CPA when distributions are large, because reclassification risk rises with the gap.

Don’t:

Don’t treat premiums as part of the reasonable wage, because they are excluded from FICA wages.
Don’t skip the W-2 reporting step, because the IRS then disallows your deduction.
Don’t take distributions before paying a reasonable salary, because that is the exact pattern courts punish.
Don’t assume a profit is required to owe comp, because distributions alone trigger it.
Don’t rely on a payroll default setting, because many systems mishandle 2% shareholder health entries.

Pros and Cons of Company-Paid Health Insurance

Pros:

FICA savings — premiums escape the 15.3% payroll tax because they are excluded from Box 5, which is real money.
Income tax neutral — the Schedule 1 deduction offsets the Box 1 income, so the premiums cost no income tax.
Clean paper trail — proper W-2 reporting gives the IRS exactly what it wants, lowering audit friction.
Above-the-line deduction — it reduces adjusted gross income, which can help with other AGI-based limits.
Simplicity — one payroll entry handles reporting, deduction eligibility, and FICA exclusion together.

Cons:

No help with reasonable comp — premiums do not raise your Box 5 wage, so they can lull you into underpaying.
Reporting fragility — miss the W-2 step and the entire deduction vanishes, a harsh all-or-nothing rule.
Earned-income cap — a low salary limits the deduction, forcing a higher wage anyway.
State variation — some states tax or treat the premiums differently, adding complexity.
Attribution surprises — family ownership can sweep relatives into 2% status unexpectedly.

Does My State Follow These Rules?

Start with the federal rule, then check your state, because conformity is never automatic. Federally, premiums are Box 1 wages, excluded from FICA, deductible by the company, and deductible by the owner on Schedule 1. Most states that piggyback on federal adjusted gross income will follow the Schedule 1 treatment, but the details differ.

Some states require the premium amount in Box 16 (state wages) even when it is excluded federally from FICA, as noted in benefit guidance. States with no income tax — such as Texas, Florida, Washington, Nevada, and South Dakota — have no state wage box concern at all, so the answer there is simply “no state income tax applies.” Always confirm with your state’s Department of Revenue before filing, since a federal-correct W-2 can still be state-wrong.

What to Do Next

Act in this order before your next payroll run or filing deadline.

Pull your last W-2 and compare Box 1 to Box 5. If your premiums are the only difference, confirm your Box 5 figure — not Box 1 — clears your market wage.
Get a market wage figure for all duties you perform, using salary data or a reasonable-comp report, and document it.
Adjust your cash salary for the rest of 2026 if Box 5 is short, so you do not repeat the gap.
Confirm premiums are flowing to the W-2 through your payroll provider, in Box 1 and out of Boxes 3 and 5.
Verify the Schedule 1 deduction on your personal return and that it does not exceed your earned income.
Call a CPA or tax attorney if you took large distributions on a low salary, since back-tax exposure is the kind of problem worth professional help — typically a few hundred to a few thousand dollars to review and correct.

FAQs

Does S-corp owner health insurance count toward reasonable compensation?

No. For tax years 2025 and 2026, company-paid premiums for a 2% shareholder appear in W-2 Box 1 but are excluded from Box 5 Medicare wages. Reasonable comp is measured by Box 5, so premiums do not count.

Where do 2% shareholder health premiums go on the W-2?

Box 1. The premiums are added to Box 1 income wages and excluded from Boxes 3 and 5, with no FICA withheld. Many payroll systems also note the amount in Box 14 for reference.

Are S-corp owner health premiums subject to FICA tax?

No. Under Notice 2008-1, premiums paid for a more-than-2% shareholder are income but are not Social Security or Medicare wages, so the 15.3% FICA tax does not apply to them.

Can I deduct my S-corp health insurance on my personal return?

Yes. A 2% shareholder takes the self-employed health insurance deduction above the line on Schedule 1, but only if the S-corp reported the premiums as wages on the W-2 first.

What happens if I forget to put premiums on the W-2?

You lose the deduction. Without W-2 reporting, the IRS position is that the shareholder gets no self-employed health insurance deduction, costing income tax savings that can run into the thousands.

How does the IRS measure reasonable compensation?

By FICA-taxable wages. The IRS and courts compare your Box 5 Medicare wages to the market wage for all services you perform, not your Box 1 income wages or your distributions.

Can the IRS reclassify my distributions as wages?

Yes. As in Watson and Glass Blocks, if your salary is unreasonably low for your duties, the IRS can recast distributions as wages and assess back FICA tax, penalties, and interest.

Does my S-corp need a profit to owe reasonable compensation?

No. Glass Blocks Unlimited held that reasonable comp is triggered by distributions, not profit. An owner can even post a loss after assessment and still owe payroll tax on reclassified wages.

Can company-paid premiums exceed my salary?

Practically, no. Your self-employed health insurance deduction cannot exceed your earned income from the S-corp, so a salary below your premium cost caps the deduction you can claim.

Who counts as a 2% shareholder?

Anyone over 2%. Under Section 1372, a 2% shareholder owns more than 2% of the stock or voting power on any day of the year. Family attribution can sweep in a spouse, child, parent, or grandparent.

Do all states tax S-corp owner health premiums the same way?

No. State conformity varies; some states require the amount in Box 16 state wages, and no-income-tax states ignore it entirely. Confirm with your state Department of Revenue before filing.

Can I amend a prior return to claim a missed premium deduction?

Yes. Notice 2008-1 allows an amended return for an earlier open year if the premiums qualify, with a statement reading “Filed Pursuant to Notice 2008-1” on top of the amended return.
