Should a physician elect S-corporation status?
Electing S-corporation status can lower a physician's self-employment tax by splitting income into reasonable salary, which carries employment tax, and distributions, which do not. The election makes sense once practice profit is high enough that the payroll-tax saving outweighs the added cost of a separate return, payroll, and reasonable-compensation documentation. It is a calculation on your numbers, not a default every physician should adopt.
Key points
- An S-corporation election lets a physician split practice profit into reasonable salary, which carries employment tax, and distributions, which do not.
- A physician taxed as a sole proprietor or single-member LLC pays self-employment tax on the full net profit of the practice.
- Reasonable compensation for a physician-owner must reflect the market value of the medical services performed and be supported by comparable pay data kept on file.
- The election adds a separate corporate return on Form 1120-S, formal payroll with deposits and filings, and an ongoing compensation analysis.
- Setting salary too low also caps retirement plan contributions, which an S-corporation calculates from W-2 wages rather than total profit.
How does the S-corporation election lower a physician's tax?
A physician operating as a sole proprietor or a single-member limited liability company pays self-employment tax under section 1402 on the full net profit of the business: the combined Social Security and Medicare tax that an employee and employer would otherwise split. When the business files Form 2553 to be taxed as an S-corporation, the physician becomes an employee of their own corporation and must be paid a reasonable salary for the work performed. That salary carries employment tax exactly as wages would.
The profit that remains after salary can be taken as a distribution, and distributions are not subject to self-employment or employment tax. The saving is the employment tax that would otherwise have applied to the portion taken as distribution rather than salary. The mechanism is straightforward; whether it pays is arithmetic on the practice's actual numbers.
What does reasonable compensation mean for a physician?
The load-bearing phrase is reasonable compensation. The salary cannot be set arbitrarily low to shrink the taxed portion. It must reflect what the physician's services are actually worth, and medicine is a field where those services command a high market value that is difficult to understate credibly. Paying an owner-physician an implausibly small salary is a well-documented examination issue, and the IRS can recharacterize distributions as wages and assess the employment tax, penalties, and interest.
The salary figure should be supported by real data on what comparable physician work pays in the same specialty and region, and the file that shows how the figure was reached is part of the strategy, not an afterthought. A CPA builds the analysis; the physician's own production, hours, and duties are the inputs.
What does the election cost, and when does it pay?
Against the saving sit real costs. An S-corporation files its own return on Form 1120-S, must run formal payroll with the associated quarterly filings and tax deposits, and needs the compensation analysis kept current. In many states a physician must operate through a professional corporation or professional LLC, which a corporate attorney forms and which may carry a state franchise or entity-level tax.
The election only makes sense once profit is high enough that the employment-tax saving on the distribution portion comfortably exceeds these added costs. Below that point the election can cost more than it saves; above it, the saving repeats every year. The right approach is to model the employment tax saved at a defensible salary, subtract the added cost of the corporation, and decide from the calculation rather than from the strategy's reputation.
When is the S-corporation election wrong for a physician?
Several factors can tilt the decision against the election. Retirement plan contributions are calculated from W-2 wages in an S-corporation, so a salary set low to save employment tax also caps what the physician may contribute to a plan, undercutting a different and often larger benefit. The qualified business income deduction under section 199A treats health care as a specified service trade or business, so it phases out at higher income levels, and the salary figure changes the calculation for physicians who still qualify.
A physician who is a W-2 employee of a hospital or group, with only modest outside income from moonlighting or consulting, may have too little independent profit to justify the structure at all. In that case the payroll and filing cost exceeds any saving, and a Schedule C with a solo retirement plan is the simpler answer.
