How to Determine a “Reasonable Salary” as a Physician S Corp Owner

In a Nutshell

• The IRS requires you to pay yourself a fair salary before taking distributions from your S Corp.
• “Reasonable” means what another physician with your specialty, experience, and workload would earn doing the same job.
• Pay yourself too little, and the IRS can reclassify your distributions as wages, plus add penalties and back taxes.
• Most physicians land somewhere between 40% and 70% of net business income as W-2 salary, with the rest as distributions.
• Good documentation is your best friend if you ever get audited.

You started an S Corp because someone, maybe your CPA, maybe a colleague at a conference, told you it would save you a ton on self-employment taxes. And they were right. Sort of.

The catch is this little phrase the IRS uses: “reasonable compensation.” It sounds simple. It is not.

Pay yourself too little salary so you can take more in distributions, and you save on payroll taxes. Pay yourself too much, and you defeat the whole point of having an S Corp in the first place. The trick is finding the sweet spot, the one that holds up if the IRS ever comes knocking.

Why “Reasonable Salary” Even Matters for Physicians

Here’s the short version of how an S Corp saves you money.

When you operate as a sole proprietor or single-member LLC, every dollar of profit gets hit with self-employment tax. That’s 15.3% on top of your regular income tax, up to the Social Security wage base, then 2.9% (plus the 0.9% additional Medicare tax for high earners) on everything above that.

With an S Corp, you split your income into two buckets:

1. Salary (W-2 wages): Subject to payroll taxes, just like any employee.
2. Distributions: Pulled from profits after salary. Not subject to payroll tax.

So if your practice nets $500,000, and you pay yourself $250,000 in salary plus $250,000 in distributions, you only pay payroll tax on the $250,000 salary portion. That distribution side? It skips the 2.9% Medicare tax and the 0.9% additional Medicare hit.

Sounds like free money, right?

It would be, except the IRS noticed people gaming this. A lot. So they require S Corp owners who actively work in the business to pay themselves a “reasonable salary” before taking distributions. And physicians, given the high earnings involved, tend to attract more attention than the average S Corp owner.

This is why getting reasonable salary for physician S Corp owner decisions right matters so much. Mess it up, and the audit can wipe out years of savings.

What Counts as “Reasonable”?

The IRS doesn’t give you a number. There’s no chart that says “anesthesiologist in Texas equals $X.” That would be too easy.

Instead, they look at what someone else would charge to do the same job you’re doing. The technical term is the “replacement cost” approach. If you suddenly disappeared and your practice had to hire someone to do exactly what you do, what would that person earn?

A few things factor in:

• Your specialty. A dermatologist and a neurosurgeon don’t earn the same. Use specialty-specific benchmarks.
• Your geography. Salaries in rural Oklahoma and downtown Manhattan look very different.
• Your experience. A physician 20 years into practice commands more than a recent residency grad.
• Your hours. Are you working 30 clinical hours a week or 60? Part-time work justifies a smaller salary.
• Your role. Are you just seeing patients, or are you also managing staff, handling billing, marketing the practice? More hats means a higher salary is justified.
• What the practice can afford. The salary has to make sense given the business’s actual revenue.

A good source for benchmarks is the Medical Group Management Association (MGMA) salary survey. It’s the gold standard. Other tools like Bureau of Labor Statistics data, Doximity reports, and Salary.com can help cross-reference.

If your MGMA median for your specialty and region is $310,000, and you decide to pay yourself $90,000 so you can take the rest as distributions, that’s going to look bad. Probably indefensible, honestly.

How to Actually Pick a Number

Okay, theory aside. Here’s how this works in practice.

Step 1: Pull Your Specialty Benchmarks

Look up the median compensation for your specialty in your region. MGMA, AMGA, and Sullivan Cotter all publish data. Your CPA or a Physician Tax Advisor likely has access to these reports.

For example:

• Family medicine: roughly $250,000 to $290,000 median
• Internal medicine: roughly $260,000 to $300,000 median
• General surgery: roughly $440,000 to $500,000 median
• Dermatology: roughly $475,000 to $550,000 median
• Anesthesiology: roughly $430,000 to $500,000 median

These are ballpark figures and shift year to year. Always pull current data.

Step 2: Adjust for Your Situation

Now adjust based on the factors above. If you only work three days a week, you can probably justify something below the median. If you also handle the practice’s hiring, marketing, and operations, you might justify something above it.

Step 3: Apply a Reasonable Split

There’s no official IRS rule on the salary-to-distribution split. You may have heard of the 60/40 rule (60% salary, 40% distributions) or even the 50/50 rule. These are informal guidelines, nothing more. The IRS has never endorsed either one.

That said, for physicians, the practical reality usually looks something like:

• Lower-revenue practices ($300K–$500K net): Salary often makes up 60% to 75% of total compensation.
• Higher-revenue practices ($800K+): Salary may settle in the 40% to 55% range, since the comparable replacement salary tops out somewhere.

Why? Because if your practice nets $1.2 million and the going rate for your specialty is $500,000, you don’t need to pay yourself $700,000 to be “reasonable.” Five hundred grand is what the market says your job is worth. The remaining $700,000 can go out as distributions.

This is one of those areas where good Physician Tax Planning earns its keep. The math gets nuanced fast.

Step 4: Document Everything

This part is unsexy and most people skip it. Don’t.

Keep a written record of:

• The salary surveys you referenced
• Your hours worked per week
• The specific roles you fill (clinical, administrative, etc.)
• Why you chose the number you chose

If the IRS ever questions your salary, the difference between “I paid myself $200,000 because that seemed fine” and “I paid myself $200,000 based on MGMA data showing the regional median for part-time family medicine is $215,000, and I work 30 clinical hours per week” is enormous.

What the IRS Actually Looks At

Audits of S Corp salaries do happen, and physicians are a known target group. A few things tend to raise flags:

• Zero or near-zero salary while taking large distributions. This is the fastest way to get audited.
• Salary that didn’t change even though the business grew significantly.
• Salary far below industry benchmarks with no documented reason.
• Distributions that look like regular paychecks, like clockwork weekly transfers, suggesting they’re really wages in disguise.

If they decide your salary was too low, they reclassify some of your distributions as wages. That means back payroll taxes, plus interest, plus penalties. And once they reclassify one year, they often look at the prior years too.

A few real cases:

• Watson v. Commissioner (2012) involved a CPA who paid himself $24,000 in salary while taking $175,000 in distributions. The IRS reclassified about $67,000 as wages. The court agreed.
• Glass Blocks Unlimited v. Commissioner (2013) had an owner taking only “loans” instead of salary. IRS reclassified the loans as wages.

These weren’t physicians, but the principle is identical. A solid Physician Tax Strategist will keep you on the right side of this line.

Common Mistakes Physicians Make

A few patterns I see over and over:

• Picking a round number with no support. “I’ll pay myself $150,000” with zero analysis behind it. Looks lazy on paper, because it is.
• Copying what a colleague does. Your colleague is not you. Different specialty, different hours, different role, different region.
• Never updating the salary. Your practice grew 40% over five years. Your salary stayed flat. That’s a red flag.
• Paying yourself only at year-end. Salary should be paid on a regular schedule, like every other W-2 employee. A lump sum in December screams “this isn’t really salary.”
• Forgetting payroll taxes. Some folks set a salary and then forget to actually run payroll, withhold taxes, and file the quarterly forms. The salary on paper means nothing if you didn’t actually pay it through proper payroll.
• Trying to DIY the whole thing. This is one area where a real Physician Tax Advisor pays for itself many times over.

A Quick Example

Dr. Patel runs a solo dermatology practice as an S Corp. Her practice nets $850,000 after expenses. She works full-time, about 45 clinical hours per week, plus another 5 hours on practice management.

Looking at MGMA data, the median dermatology salary in her region is around $510,000. Given her full-time clinical load plus admin work, that’s a defensible benchmark.

So she sets her W-2 salary at $510,000. The remaining $340,000 flows through as distributions.

The savings: she avoids the 2.9% Medicare tax (and the 0.9% additional Medicare tax for high earners) on that $340,000 distribution. That’s roughly $13,000 to $16,000 saved in payroll taxes, year after year, just from structuring this correctly.

If she had tried to be more aggressive, say, paying herself $250,000 and taking $600,000 as distributions, she might save another $11,000 or so in payroll tax. But that salary number is so far below the regional median for a full-time dermatologist that it’s almost begging for an audit. Not worth it.

Why a Physician-Focused Tax Pro Matters

A general CPA who does taxes for plumbers, restaurants, and the occasional doctor probably isn’t the right fit for this. The reasonable salary question gets specialty-specific fast. The tax pro you want has worked with dozens of physicians, knows the MGMA data inside out, and understands the unique dynamics of medical practice income.

Good Physician Tax solutions typically include:

• Annual reasonable compensation analysis with documentation you can actually use in an audit
• Coordination between your salary, retirement contributions (solo 401(k), defined benefit plans), and distributions
• Quarterly check-ins so your numbers reflect how the practice is actually performing
• Audit support if the IRS ever asks questions

The fees usually pay for themselves several times over in tax savings, and that’s before you factor in the peace of mind.

FAQs

What happens if I only take distributions and skip the salary altogether?

This is the fastest way to get audited. The IRS sees zero W-2 wages from an active S Corp owner and treats it like a flashing red light. If they reclassify your distributions as wages, you’ll owe back payroll taxes, interest, and penalties, sometimes going back several years. Don’t do it.

Does my practice have to be profitable for me to take a salary?

Not exactly. If your practice runs at a loss, the IRS won’t expect you to pay yourself a salary you can’t afford. But if there’s any meaningful profit, you need to run payroll before pulling distributions. And no, you can’t just skip salary in lean years and “make it up” later by paying yourself a huge salary in a strong year. The salary should track with how the practice is actually doing each year.

Can I just pay myself once a year in December?

You shouldn’t. Salary should be paid on a regular schedule, monthly, biweekly, whatever, just like any W-2 employee. Lump-sum year-end payments look suspicious and weaken the case that what you’re paying is actually salary. Set up real payroll and run it consistently.

How does the IRS even check if my salary is reasonable?

A few ways. They might compare your salary to public data for your specialty and region. They look at your distribution-to-salary ratio. They check whether your salary kept pace with practice growth. And if you get pulled for an audit on something else, the salary question often comes up as part of the broader review. A solid paper trail showing how you arrived at your number is the best protection.

What about health insurance premiums I pay for myself?

For S Corp owners holding more than 2% of the company, health insurance premiums get reported as wages on your W-2 (in Box 1, but not Boxes 3 or 5). You then deduct them on your personal return. It’s a quirky setup, and getting it wrong on payroll is a common mistake. Your payroll provider or Physician Tax Advisor should handle this correctly.

Do I need payroll if I’m the only person in my practice?

Yes. The “only employee” thing doesn’t get you out of payroll obligations. If you’re an active S Corp owner pulling income from the business, you need a real salary, real payroll, and real tax filings. Spouse-only practices, solo practices, it doesn’t matter.

What if I work part-time or only see patients a few days a week?

Your salary should reflect that. Part-time work justifies a lower salary, as long as you can document the hours. Pull part-time benchmarks from MGMA or similar sources, and keep records of your actual schedule. A 25-hour-a-week physician shouldn’t be paid the full-time median, but they also shouldn’t be paid pennies.

Can my spouse take a salary from the S Corp too?

If your spouse genuinely works in the practice, yes. The salary still has to be reasonable for the work they actually do. Paying a spouse who doesn’t really work there, or paying them $200,000 to do light bookkeeping, is the kind of thing that gets practices in trouble.

How often should I revisit my reasonable salary?

At least once a year. Practice revenue changes. Your hours change. Specialty benchmarks change. A salary that was perfectly reasonable in 2022 might be too low in 2026 if your practice doubled in size. Make it part of your annual planning conversation with your tax pro.

If you’re running a practice as an S Corp and you’ve been guessing at your salary, or just doing whatever your last accountant set up three years ago, it might be time for a fresh look. Pull the data. Run the numbers. Document the reasoning. Or better yet, sit down with someone who does this for physicians all day long and let them stress-test your setup before the IRS does it for you.

Your future self, the one not dealing with back taxes and penalties, will thank you.
