What's a Reasonable S-Corp Salary for Your Specialty?

Jun 29
8 min read

Of all the numbers on a physician's S-Corp return, the reasonable salary is the one the IRS reads first. Set it too low and the distributions that were supposed to skip self employment tax can be reclassified as wages, with penalties on top. Set it at the full specialty median and the election barely moves the needle, because almost everything runs through payroll anyway. The defensible number sits between those two points, and where it lands depends on your specialty, your hours, and what the market pays someone doing your work.

The reasonable salary question lives inside the larger S-Corp decision, which S-Corp for Physicians: Is It Right for You? walks through end to end. Here the focus is narrower: what counts as reasonable for a physician, how the IRS tests it, and where the specialty benchmarks actually land.

What Does Reasonable Compensation Mean for a Physician S-Corp?

When a physician's LLC or corporation is taxed as an S-Corp, the owner-physician is both an employee and a shareholder. The IRS requires that owner employees who provide services be paid a reasonable salary through W-2 payroll before any profit comes out as a distribution. There is no fixed formula and no safe harbor percentage. Reasonable means what the open market would pay someone with your training, specialty, and experience to do the same work.

The reason the rule exists comes down to how the two streams are taxed:

The salary is subject to FICA (Social Security plus Medicare).
The distribution is not subject to FICA or the 0.9% additional Medicare tax.

Because distributions skip that layer, there is a built in pull toward setting the salary as low as possible. The reasonable compensation requirement is the IRS's check on that pull. For physicians the check has teeth, because physician pay is well documented and specialty specific, so a salary that sits far below the market figure stands out.

How Does the IRS Decide Whether a Physician's Salary Is Reasonable?

There is no single test. The IRS and the courts weigh a set of facts, and for a physician the most important ones are:

Specialty and the clinical work performed
Years of experience and board certification status
Geographic region and local market rates
Hours worked, including part time or reduced schedules
Administrative or leadership duties on top of clinical work
What comparable physicians earn at similar practices
What the practice can actually afford to pay

The comparison point is published compensation data. The Medical Group Management Association (MGMA) survey is the one referenced most often, alongside AMGA and SullivanCotter. These surveys break compensation down by specialty, region, and percentile, and the IRS is familiar with all of them. A salary that lands within a defensible range of the relevant benchmark is straightforward to support. A large gap between the salary and the benchmark is what invites a closer look.

The case physicians hear about most is Watson v. Commissioner, where an accountant paid himself a small salary on a much larger S-Corp profit. The court found the salary unreasonably low and reclassified the distributions as wages. Physicians are more exposed than the accountant in that case, not less, because the benchmark data for medicine is specific and public.

What Are the Reasonable Salary Benchmarks by Specialty?

The table below shows approximate median total compensation by specialty. Two cautions before reading it. First, these are total compensation figures, not recommended S-Corp salaries, and your defensible salary does not have to match the median. Second, the numbers move every year, so the current MGMA survey is always the reference point rather than any figure printed here.

Specialty	Approximate median total compensation
Family Medicine	$290,000 to $320,000
Internal Medicine	$300,000 to $330,000
Emergency Medicine	$375,000 to $400,000
Anesthesiology	$450,000 to $480,000
Dermatology	$480,000 to $520,000
Orthopedic Surgery	$620,000 to $660,000
Cardiology (Invasive)	$620,000 to $720,000

The pattern worth noticing is that higher-benchmark specialties leave less room for the salary and distribution split. A family medicine physician netting $400,000 sits well above the specialty median, so a defensible salary can be set below net income and still hold up, leaving a meaningful distribution. An orthopedic surgeon netting $500,000 sits below the specialty median, so a defensible salary may absorb most of the income, and the distribution portion is small. Same election, very different room to work with, driven entirely by where net income falls relative to the specialty benchmark.

How Do You Land on a Defensible Number?

A common rule of thumb sets the salary at 60% of net income. It is a starting reference, not IRS guidance, and leaning on it without the underlying facts is how salaries drift too low. The defensible number comes from working the facts in both directions:

The starting point is the specialty benchmark for the region and percentile.
Part time hours, fewer years in practice, or practice revenue below the specialty norm pull the number down.
Administrative or leadership roles, or a high revenue practice, push it up.
The last check is against net income. When net income sits close to the specialty median, the salary absorbs most of it and the distribution room is naturally narrow.

Consider Dr. Coleman, a dermatologist who nets $480,000 through her solo PLLC taxed as an S-Corp. The dermatology benchmark sits around $450,000 to $500,000. Because her net income lands inside that band, a defensible salary is going to be close to the full amount, which leaves only a thin slice to take as a distribution. The mechanic still works, only the salary faces FICA and the distribution does not, but the slice that escapes FICA is small. A physician in a lower benchmark specialty earning the same $480,000 would have far more distribution room. The number is specialty specific, not a flat percentage.

In a group practice the analysis multiplies, because every physician-shareholder needs an individually defensible salary, and the distribution still flows pro rata by ownership. That interaction is one of the things that makes the S-Corp vs Partnership for Physician Groups decision more involved than the solo version.

What Happens If You Set the Salary Too Low?

If the IRS decides the salary was unreasonably low, it can reclassify distributions as wages, going back across multiple years. When that happens:

Back FICA is assessed on the reclassified amount, both the employer and employee shares.
Failure-to-deposit penalties on the unpaid payroll taxes apply.
Interest runs from the original due dates.
The S-Corp's returns can be reopened for the affected years.

The practical takeaway is that an aggressive salary does not just risk losing the benefit. It can turn into a larger bill than running the election conservatively would have produced in the first place. The reasonable salary is the part of the S-Corp that has to be set honestly, documented against the benchmark data, and revisited each year as compensation surveys and the physician's own hours change.

How the Salary Ripples Into Retirement, QBI, and State Costs

The salary number does more than set the FICA line. It feeds three other decisions:

Retirement contributions. Employer profit-sharing contributions are capped at 25% of W-2 wages, and elective deferrals are based on the salary as well. A salary set low to trim FICA also lowers the ceiling on retirement contributions, which for many physicians is the more valuable lever. The two have to be modeled together, not in isolation.
The QBI deduction. In an S-Corp, the W-2 salary reduces the qualified business income left for the Section 199A deduction. For 2026 the deduction phases out for specified service trades or businesses, which includes medicine, between $201,750 and $276,750 of taxable income for single filers and between $403,500 and $553,500 for joint filers. Most physicians in practice sit above the top of that range, where the QBI deduction is zero regardless of the salary. For the smaller group inside the phase out range, the salary and the QBI deduction interact and need to be modeled together.
State payroll costs. The salary drives state payroll taxes and surcharges, which vary widely. New York's metropolitan commuter transportation mobility tax applies to payroll in the NYC metro area, for example, and state unemployment taxes attach to wages. The salary that looks right on the federal side can carry a different cost depending on the state, which is part of the broader state picture covered in S-Corp State Taxes: CA Franchise Tax and NY/NJ Surcharges.

Next Steps for Setting Your Number

The reasonable salary is not a set it once decision. It is worth revisiting annually, because the benchmark surveys update, your hours and role shift, and the practice's revenue moves. A defensible process looks like pulling the current specialty data, adjusting for the physician's actual facts, documenting the basis for the number, and checking it against the retirement and QBI math before payroll is set for the year.

FAQs

What is a reasonable S-Corp salary for a physician?

There is no single figure. A reasonable salary is what the market would pay a physician of your specialty, experience, region, and hours to do the same work, measured against published benchmarks like the MGMA survey. The defensible number is one you can support with that data and your own facts, not a flat percentage of income.

Is the 60% rule a real IRS standard?

No. Setting the salary at 60% of net income is a rule of thumb some advisors use as a starting point, but it is not in the tax code or IRS guidance. The actual standard is reasonable compensation based on facts and circumstances, and a percentage that ignores your specialty benchmark can land you too low.

Does my salary have to match my specialty's median?

No. Your salary needs to be defensible relative to the benchmark data, not identical to the median. Part time hours, fewer years in practice, or practice revenue below the specialty norm can all support a number below the median, as long as the basis is documented.

What salary is low enough to draw IRS attention?

There is no bright line, but the larger the gap between your W-2 salary and the published benchmark for your specialty, the more scrutiny it invites. A salary far below the specialty data while large distributions come out is the pattern the IRS looks for, and it can reclassify those distributions as wages with penalties and back FICA.

How often should I revisit the number?

Annually. Compensation surveys update each year, and your own hours, role, and practice revenue change. Setting the salary once and leaving it in place is one of the more common ways the number drifts out of a defensible range.

Does a lower salary cost me anything besides audit risk?

Yes. A lower salary reduces the ceiling on employer retirement contributions, which are capped at 25% of W-2 wages, and it can affect the QBI math for physicians inside the phase out range. Trimming FICA with a low salary can cost more than it saves once the retirement impact is counted, which is why the salary is modeled alongside the rest of the plan.
