Tax Planning for Medical Practice Owners

Why ownership changes everything

An employed physician mostly plans around a paycheck. A practice owner controls the business itself: how it is organized, how owners are paid, what benefits it offers, what assets it holds and how it will eventually be sold. Each of those choices has a tax consequence.

Entity structure

Most physician practices are organized as professional corporations, professional LLCs or partnerships, depending on state licensing rules. For tax purposes the main choices are a partnership, an S corporation or, less often, a C corporation.

• S corporation. Owners take a reasonable salary subject to payroll tax and receive remaining profit as distributions, which are not subject to Social Security or Medicare tax. This is the most common structure for single-owner and small group practices. See S corp vs. LLC for physicians.
• Partnership. Offers more flexibility for unequal profit allocations among physicians, but general partners typically pay self-employment tax on their full share.
• C corporation. Taxed at a flat 21%, but profits paid out as dividends are taxed again, and health care C corporations generally cannot use the qualified small business stock exclusion. Rarely the best fit for operating practices.

State rules matter. California, for example, generally requires physicians to practice through a professional medical corporation rather than an LLC.

Owner compensation

In an S corporation, the IRS requires owners who work in the business to receive reasonable compensation before taking distributions. Setting salary too low invites audit risk; setting it too high wastes payroll tax. Compensation also drives retirement plan contributions, since employer contributions are based on W-2 pay.

Retirement plans for the practice

A practice can combine a 401(k) with a profit-sharing component and, for owners with high income and stable cash flow, a cash balance plan. In 2026 the total annual addition limit for defined contribution plans is $72,000 per person (plus catch-up contributions), and cash balance plans can add much more. The design has to pass nondiscrimination testing, so staff contributions and demographics shape what owners can put away. See cash balance plans.

The pass-through entity tax

Most states with an income tax now let S corporations and partnerships elect to pay state income tax at the entity level, which makes it deductible federally and avoids the SALT cap. For practice owners above about $600,000 of income, the SALT deduction falls back to $10,000, so this election is often worth five figures a year. See the PTET guide and your state page.

Practice deductions owners often miss

• Section 179 expensing (up to $2,560,000 in 2026, phasing out above $4,090,000 of purchases) and 100% bonus depreciation for qualifying equipment.
• Health insurance for S corporation owners, which is added to W-2 wages and then deducted above the line.
• Accountable plans to reimburse owners for home office, cell phone and mileage costs.
• Continuing medical education, licenses, DEA registration, board fees and malpractice premiums.
• Hiring a spouse or adult children for real work at reasonable pay, which can also fund their retirement accounts.

Owning your building

Many physicians buy their office or surgery center real estate through a separate LLC and lease it to the practice. Rent becomes a practice deduction, the building generates depreciation (accelerated through cost segregation), and the real estate can be kept or sold separately when the practice is sold.

Partner buy-ins and buy-outs

How a buy-in is structured (purchase of equity, purchase of hard assets, or reduced compensation over several years) changes who gets the deduction and when. Retiring partners similarly face different taxes depending on whether payments are treated as purchase price or as income.

Planning for a sale

If you may sell to private equity, a hospital or a younger physician, start planning at least two to three years before a deal. Entity structure, how goodwill is allocated, rollover equity, earnouts, and your state of residence at closing all affect the after-tax result.
