What tax strategies apply to a medical practice?

A medical practice's largest levers are usually entity and management-company structure, retirement plan design sized to physician income, cost segregation where the practice owns its building, and equipment expensing. Reasonable compensation for owner-physicians and the pricing of any management fee between related entities are the two issues the IRS examines most closely in this industry.

Key points

A medical practice's largest tax levers are entity and management-company structure, retirement plan design, cost segregation on an owned building, and equipment expensing.
A management company must provide genuine administrative, billing, staffing, or equipment services to the clinical entity, and its fee must be priced at arm's length.
A cash balance or defined benefit plan layered on a 401(k) with profit sharing permits far larger deductible contributions, sized each year by an enrolled actuary.
Cost segregation reclassifies building components and specialized medical infrastructure into shorter depreciation periods, accelerating deductions into the early years of ownership.
Owner-physicians in an S corporation must pay themselves a defensible salary for clinical and management work before taking distributions.

How should a medical practice structure its entities?

A medical practice generates high, stable income from a few highly paid owners, the profile where deliberate structure pays off. Entity choice comes first: an S corporation filing Form 1120-S changes how owner-physicians are paid, a partnership filing Form 1065 changes how partners are admitted, and each shapes retirement plan and benefit design.

Many practices separate the clinical entity from a management company that provides administrative services, billing, staffing, or equipment under a written services agreement. Done for real business reasons, this improves liability separation, simplifies admitting partners, and organizes how income and benefits flow. The structure has to reflect genuine services and genuine substance, not a paper arrangement, so it should be built with a CPA and a healthcare attorney rather than copied from a template; state corporate-practice-of-medicine rules also govern who may own the clinical entity.

Which retirement plan produces the largest deduction for physicians?

Retirement plan design is often the single largest deductible lever. Physician income is high enough to support plans well beyond a basic 401(k). A 401(k) with profit sharing captures a meaningful amount, and a cash balance or defined benefit plan layered on top can permit far larger deductible contributions, particularly for older owner-physicians.

An enrolled actuary sizes the funding each year, and a third-party administrator runs the nondiscrimination testing the plan must pass. The plan is engineered around the practice's staff census, balancing the benefit to owners against the cost of covering employees. For a practice with steady income and a modest headcount, this is usually where the largest savings live; the plan must be adopted and funded by the deadline for the year it covers.

What do cost segregation and equipment expensing do for a practice?

Cost segregation applies when the practice owns its building. Rather than depreciating the whole property over the long period for nonresidential real property, an engineering-based cost-segregation study identifies components, fixtures, specialized medical infrastructure such as dedicated plumbing and electrical for exam rooms, and certain finishes that can be depreciated over much shorter periods. This accelerates deductions into the early years of ownership, and it pairs naturally with owning the building through a separate entity that leases it back to the practice at a documented market rent.

Equipment expensing addresses the reality that practices buy expensive equipment regularly. The section 179 election and bonus depreciation, both reported on Form 4562, allow the cost of qualifying equipment to be deducted in the year it is placed in service rather than spread over many years. Timing purchases so the deduction lands in the year with the income it offsets is a recurring planning conversation.

What does the IRS examine most closely in a medical practice?

Two issues draw the closest examination. The first is reasonable compensation for owner-physicians in an S corporation: owners must pay themselves a defensible salary for their clinical and management work before taking distributions, and a salary far below what a hospital would pay an employed physician in the same specialty is what examiners look for. The second is the management fee between related entities. A fee charged by a management company to its own practice must be set at an arm's-length level supported by the services actually provided; an inflated or unsupported fee is a classic examination target.

The limits are real. Cost segregation does nothing for a practice that leases its space, and accelerated depreciation is recaptured when the building is sold. A defined benefit plan requires a multi-year funding commitment that volatile income may not sustain. A management company that performs no real work adds cost and examination exposure without benefit. Each strategy is sound when supported by contemporaneous records and fragile when it is not, so review the set as a system with a CPA rather than piecemeal.
