What Is the Average Medical Practice Profit Margin? #
Physician practices earned a 7.3% net profit margin, measured as net income divided by total receipts on corporate tax returns (IRS Statistics of Income, 2022).
The figure sits below what many owners expect because corporations deduct the salaries they pay their owner-physicians before arriving at net income. It measures what is left after the doctors are paid, not what the practice generates for them.
That distinction is not a technicality. It determines whether this benchmark is usable for a given practice at all, and the next section sets out when it is.
Why the Figure Is Lower Than Physicians Expect #
In an incorporated practice, the physicians are employees of the corporation. Their compensation is a deductible expense, taken before net income, exactly like rent or medical supplies. A practice that collects a dollar, pays the treating physician a large share of it, covers staff and premises with most of the rest, and retains a few cents, has done nothing unusual.
This is why the same practice can look completely different depending on which tax form describes it. A solo physician filing Schedule C as a sole proprietor does not pay themselves a deductible salary. What the business earns after expenses is their income, so the profit line contains the physician's own pay and reads many times higher than a corporate margin for an identical practice.
The practical reading of 7.3% is therefore narrow and useful: it is what a group practice retains as a business after it has paid its doctors, its staff and its premises. It is a measure of the practice as an enterprise, not of medicine as a career.

Who the Figure Describes #
The margin covers incorporated practices. Alongside 218,066 physician offices with paid employees (Census CBP, 2023), Census counts 239,886 practices that operate with no paid employees (Census Nonemployer Statistics, 2023).
A minority of those owner-run practices are incorporated, and their returns are inside the IRS figure. Most file as sole proprietors, whose results are reported on individual returns and are not.
The population the margin actually describes is therefore group practices: incorporated, staffed, filing a corporate return. That is the smaller half of the profession by business count and by far the larger half by patient volume, payroll and receipts. For a multi-physician practice with employees, this benchmark is the right one. For a solo practitioner filing Schedule C, it is the wrong one, and the section above explains why.
What Counts as a Medical Practice #
Offices of Physicians, except Mental Health Specialists (NAICS 621111) comprises establishments of health practitioners holding the degree of M.D. or D.O. primarily engaged in the independent practice of general or specialised medicine or surgery, other than psychiatry and psychoanalysis. Census notes that these practitioners operate private or group practices in their own offices, such as centers and clinics, or in the facilities of others, such as hospitals or HMO medical centers.
That last clause matters for anyone reconciling practice counts with hospital employment. A physician group can practice inside a hospital building and still be classified as an office of physicians, because the classification follows the business, not the address.
Offices of Physicians, Mental Health Specialists (NAICS 621112) takes psychiatrists and psychoanalysts who hold the same M.D. or D.O. degrees. The split is by specialty, not by qualification or setting.
Several kinds of care that patients would describe as a medical practice sit in different industries altogether. Dentists, optometrists, chiropractors, physical therapists and other health practitioners each have their own classifications. Freestanding outpatient care centers, diagnostic laboratories and home health agencies are separate again, and hospitals are a different industry group entirely. None of them are inside the figures on this page.
What Moves a Practice's Margin #
A practice controls its costs and, in most cases, does not control its prices. That asymmetry shapes everything about how the margin behaves.
Payer mix. Reimbursement is set by contract with commercial insurers and by administered fee schedules for public programs. A practice can change which payers it accepts and what procedures it performs, but it cannot reprice an existing contract the way a retailer reprices a shelf.
Staffing ratio. The number of clinical and administrative staff supporting each physician is the largest controllable cost after physician compensation itself. Billing, prior authorisation and coding work scales with payer complexity rather than with patient volume.
Ancillary services. Imaging, laboratory work and dispensing performed in-house change the revenue mix and the capital base at the same time, which is why two practices of the same size can report very different margins without either being mismanaged.
Fixed costs. Premises, malpractice cover and clinical systems are largely fixed against patient volume, so the margin is sensitive to utilization in a way that a variable-cost business is not.
More Practices Run Without Staff Than With #
Practices without paid employees outnumber those with them, by our calculation from the two Census releases. Slightly more than half of all physician practices in the country carry no payroll.
That shapes how the margin should be read. The IRS figure describes group practices with staff and a corporate structure, which is the smaller half of the profession by business count, though by far the larger half by patient volume and payroll.
It also explains why practice counts and physician counts diverge so widely. A nonemployer practice is one business regardless of whether the physician works full time in it, and many exist alongside employment elsewhere: locum work, part-time consulting, a small private list maintained beside a hospital post. Counting businesses is not counting doctors.
Benchmarking Your Own Practice #
To compare a practice against this figure, divide net income by total receipts from the corporate return, after physician salaries. A solo practitioner filing Schedule C keeps physician pay inside the profit line, so that number will read far higher and is not comparable.
The margin itself is on this page and is not in the report: it comes from IRS Statistics of Income, which our reports do not carry. What the report adds is the Census picture of the industry around it.
Three further checks make the comparison honest. Use the same year, because a single national margin moves with the reimbursement and cost environment of its tax year. Use total receipts rather than collections net of refunds, since that is what the IRS measure uses. And treat the figure as a central tendency for a group of practices that ranges from single-specialty to large multi-site, not as a target.

How This Margin Is Measured #
The margin is net income divided by total receipts for active corporations in the IRS Statistics of Income group for offices of physicians, tax year 2022, the most recent year published.
Four limits travel with it, and they are the source's own. It is a tax-return measure rather than an operating margin, so it reflects tax accounting including depreciation and interest. It covers corporations only, which excludes sole proprietorships and partnerships and therefore skews toward larger incorporated practices. It represents the IRS group named, not a narrower specialty within it. And Statistics of Income runs roughly three years behind the current year, which is why the latest published figure is for 2022 rather than something more recent.
The practice counts here use the matching Census category, which includes offices of mental health specialists. Hospitals are a separate industry and are not in either figure. Practice counts are Census County Business Patterns (2023); counts of practices with no employees are Census Nonemployer Statistics (2023).
