Tax Strategy for Surgeons: Entity, Retirement, and Real Estate Planning

Surgeons present a tax profile distinct from other physicians in three ways. Income is higher and more concentrated, it frequently arrives from multiple sources including practice distributions, facility fees, and ambulatory surgery center ownership, and the career arc is shorter, which compresses the window for tax-deferred accumulation.

Entity Structure and Multiple Income Streams

The clinical practice belongs in a professional entity taxed as an S corporation. Above reasonable salary, distributions escape the 2.9% Medicare tax and the 0.9% additional Medicare tax, which at surgeon income levels is a meaningful recurring number.

Ambulatory surgery center ownership is separate and should stay separate. ASC income arrives on a K-1 from a partnership or LLC in which the surgeon typically does not materially participate in the business operations, though he does perform cases there. That distinction drives whether the income is subject to self-employment tax and whether it is passive for IRC Sec. 469 purposes. Getting the characterization wrong in either direction is expensive, and it is worth a specific memo rather than an assumption.

Locums, expert witness work, and device consulting should run through the same S corporation rather than a Schedule C, so that the income participates in the reasonable compensation framework instead of being fully exposed to self-employment tax. Our entity restructuring guide covers the consolidation decision.

Reasonable Compensation

We typically benchmark against specialty survey medians for the case volume actually performed, which for an orthopedic or cardiothoracic surgeon frequently means salary in the $400,000 to $600,000 range. The residual, which is real when a practice has ancillary imaging, physical therapy, or staff leverage, is distributed. Because surgeons run high salaries anyway, the S corporation benefit is smaller in percentage terms than for a lower-earning specialty. The main value is the retirement plan capacity that a large salary supports. See how a reasonable compensation analysis is built.

Retirement: Front-Load While the Income Is There

The stack is a 401(k) with profit sharing reaching roughly $72,000 in 2026, plus a cash balance plan sized actuarially. A 52-year-old surgeon can commonly fund $200,000 to $280,000 into a cash balance plan annually. At a combined 40% marginal rate, that is over $100,000 of deferred tax per year, and the plan can be terminated and rolled to an IRA at retirement or on practice sale.

Accountable Plan Reimbursements

Surgeons carry an unusually large set of legitimate business costs: loupes and personal instruments, board recertification, malpractice tail coverage in some arrangements, society memberships, travel between hospitals and surgery centers, and a home office used for chart review and case planning.

None of these are deductible personally under current law. A written accountable plan under Treas. Reg. Sec. 1.62-2 lets the practice reimburse them, deduct them, and deliver the cash to the surgeon tax-free. Mileage between two facilities on the same day is business mileage, and for a surgeon covering three sites that alone is often several thousand dollars per year. Our accountable plan guide covers substantiation requirements.

The Augusta Rule

Under IRC Sec. 280A(g), the practice can rent the surgeon's residence for up to fourteen days per year for legitimate business meetings. The rent is deductible by the practice and excluded from the surgeon's income.

For a surgical group, quarterly partner meetings and an annual strategic planning session are natural fits. Support the rate with quotes from comparable local conference space, keep a signed rental agreement, and retain an agenda and attendance list for each date. Fourteen days at $2,000 produces $28,000 of deduction with no corresponding income. Details are in our Augusta Rule article.

Cost Segregation on Owned Facilities

Surgery center buildings are excellent cost segregation candidates. Medical gas systems, dedicated electrical for imaging and OR equipment, specialized HVAC with pressurization and filtration, backup power, casework, and finish-heavy build-outs push reclassification into the 30% to 40% range on many studies. With 100% bonus depreciation restored for property acquired after January 19, 2025, that basis is deductible in year one. See our medical facility cost segregation guide.

QBI Is Off the Table

Surgery is health, which is a specified service trade or business under IRC Sec. 199A(d)(2). At surgeon income levels the deduction is fully phased out, and the OBBBA expansion of the phase-in range in 2026 does not change that outcome.

Frequently Asked Questions

Is surgery center K-1 income subject to self-employment tax?

It depends on the entity form and the surgeon's role. A limited partner or non-managing LLC member receiving a distributive share of facility profit generally is not subject to self-employment tax, but guaranteed payments for services are. The characterization should be documented rather than assumed, given the amounts involved.

How much can a surgeon defer into retirement plans each year?

A 401(k) with profit sharing reaches roughly $72,000 in 2026. A cash balance plan added on top commonly allows $200,000 to $280,000 for a surgeon in his early fifties, because the limit is actuarially determined by age and target benefit rather than a flat dollar cap.

Do surgeons get any Section 199A QBI deduction?

Not on clinical income. Health is a specified service trade or business under IRC Sec. 199A(d)(2) and the deduction fully phases out at surgeon income levels. Surgery center income may warrant separate analysis if the facility entity is genuinely a facility business rather than a medical services business.

Should locums and expert witness income go on a Schedule C?

Usually not. Running it through the existing S corporation lets it participate in the reasonable compensation framework instead of being fully exposed to self-employment tax, and it consolidates retirement plan contribution capacity in one entity rather than splitting it.

What reclassification percentage do surgery center buildings achieve?

Commonly 30% to 40% of depreciable basis, higher than general office. Medical gas, OR-specific electrical, pressurized and filtered HVAC, backup power, and heavy casework all move into five, seven, and fifteen-year property rather than the 39-year structure.
