Medical practice tax deductions: What owner-doctors can (and can't) write off

You bought a $42,000 ultrasound machine in September. Your accountant told you it qualifies for Section 179 expensing, so you deducted the full amount in the current tax year. Good. You also deducted $8,400 for continuing medical education expenses, $3,200 for professional association dues, and $1,800 for medical journal subscriptions. Also good.

Then you deducted the $6,500 country club membership because you "network with referring physicians there." That will not survive an audit. You deducted $14,000 for your home office based on your home's total square footage rather than the dedicated office space. That will be adjusted. And you paid your 16-year-old son $28,000 for "administrative work" without documented hours. If he cannot prove the work, that deduction carries penalties on top of the disallowance.

Medical practice tax deductions are generous. The code provides substantial write-offs for equipment, operations, staffing, and professional development. But the line between legitimate deduction and audit risk is clear, and assumptions rather than rules create liabilities that arrive as surprises.

Equipment and technology deductions

Section 179 expensing. Medical equipment, office furniture, computers, and technology purchased and placed in service during the tax year can be deducted in full up to $1,250,000 for TY2025. This includes exam tables, diagnostic equipment, EHR hardware, phone systems, and practice management technology. The equipment must be used more than 50% of the time for business purposes. The guide to adjusting journal entries covers how to record Section 179 elections and depreciation correctly in the general ledger.

Bonus depreciation. For equipment exceeding Section 179 limits, bonus depreciation provides an additional first-year deduction. The percentage has been phasing down: 60% in 2024, 40% in 2025, and 20% in 2026. Timing major purchases around these thresholds can significantly affect your tax position.

Leased equipment. Lease payments on medical equipment are deductible as operating expenses in the year paid. A $3,500 monthly lease on an X-ray system yields a $42,000 annual deduction without the capital outlay of purchase.

What you cannot deduct: equipment used primarily for personal purposes; equipment purchased but not placed in service during the tax year; and home gym equipment regardless of wellness rationale.

Staffing and compensation deductions

Employee wages and benefits. All compensation paid to employees is deductible: base pay, overtime, bonuses, health insurance premiums, retirement plan contributions (401k match, SEP-IRA, defined benefit plan), disability insurance, and fringe benefits. These are deductible to the practice and generally not taxable income to the employee, making them one of the most tax-efficient forms of compensation. Employer payroll taxes (FICA at 7.65%, FUTA, state unemployment) are also deductible business expenses.

Contractor payments. Payments to independent contractors are deductible with 1099 reporting and do not require payroll tax obligations, but the classification must be legitimate. The guide to physician contractor vs employee classification covers the rules that determine which treatment applies.

Family employees. Paying family members for legitimate, documented work is deductible when compensation is reasonable. Paying your spouse $65,000 as office manager is legitimate; paying your teenager $28,000 for vague "help" without time records is an audit target.

Facility and operating expense deductions

Rent and lease payments. Monthly rent is fully deductible. If you own the building through a separate entity and lease it to the practice, payments are deductible to the practice and rental income to the property entity, which then deducts mortgage interest, depreciation, and maintenance. Medical practice overhead benchmarks show rent typically running 5% to 10% of collections, which helps evaluate whether an owner-leased arrangement is market-rate.

Utilities, supplies, and insurance. Electricity, water, internet, phone, cleaning, medical supplies, and clinical consumables are all deductible in the year paid. Malpractice, general liability, property, workers' compensation, and cyber liability insurance are fully deductible business expenses.

Professional services. Fees to accountants, attorneys, billing companies, and IT providers are deductible. A properly structured chart of accounts ensures these are categorized correctly from the first transaction, keeping deductions audit-ready.

Professional development and membership deductions

Continuing medical education. Registration, travel, and lodging are deductible. The education must maintain or improve skills in your current profession. A dermatologist attending a dermatology conference qualifies. Attending a real estate seminar does not.

Professional dues and memberships. AMA, specialty society, state medical association, and hospital staff fees are deductible. Country club dues are not, even for networking. This deduction was eliminated in 2017 and practice owners still claim it.

Licenses and subscriptions. State medical license fees, DEA registration, board certification and maintenance, credentialing costs, medical journal subscriptions, and clinical reference services are all deductible.

The deductions that create audit risk

Home office deduction. Legitimate if you have a dedicated space used regularly and exclusively for practice administration. Calculate based on dedicated square footage divided by total home square footage. A 150-square-foot office in a 2,400-square-foot home allows 6.25% of qualifying housing expenses. Claiming 25% because "I work from home a lot" invites adjustment.

Vehicle deduction. Deductible for business use: travel between locations, hospital visits, CME travel. Not deductible for commuting. Track mileage with a log recording date, destination, purpose, and miles. According to the IRS standard mileage rates, the 2025 rate is 70 cents per mile for business use. Without a contemporaneous log, the deduction is indefensible.

Meals and entertainment. Business meals with a documented business purpose are 50% deductible. Entertainment expenses, including sporting events, concerts, and theater, are not deductible regardless of whether business is discussed. A dinner with a referring physician discussing a patient's case is 50% deductible. Taking the same physician to a basketball game is not.

Charitable contributions. C-corporations can deduct up to 10% of taxable income; S-corps and partnerships pass deductions through to owners. Donated medical services (free care) are not deductible; the tax code does not permit deduction of donated service value.

Year-round tax planning versus year-end scrambling

Minimizing tax burden sustainably requires planning throughout the year, not a December scramble.

Quarterly estimated tax reviews. Compare actual income and deductions to projections each quarter. Adjust estimated payments and spending decisions accordingly before the window closes.

Equipment purchase timing. Plan major purchases around Section 179 limits and depreciation schedules. A $60,000 purchase in December of a high-income year is worth more in tax savings than the same purchase in January of an uncertain year.

Retirement plan contributions. A SEP-IRA allows up to 25% of net self-employment income. A defined benefit plan can shelter over $200,000 annually for older, high-earning owners. Both reduce current taxable income while building retirement wealth.

Frequently asked questions

Can a physician deduct health insurance premiums for themselves as a practice owner?

Yes. The self-employed health insurance deduction allows 100% of premiums for yourself, spouse, and dependents as an above-the-line deduction on Schedule 1. The deduction cannot exceed the practice's net profit and is unavailable for any month you were eligible for employer coverage through a spouse. Medical, dental, and qualifying long-term care premiums all qualify.

What is the Qualified Business Income (QBI) deduction and do physicians qualify?

The Section 199A QBI deduction allows pass-through owners to deduct up to 20% of qualified business income, but medicine is a Specified Service Trade or Business (SSTB). The deduction phases out above income thresholds (for TY2025: begins at $197,300 taxable income, fully eliminated at $247,300; double those figures for MFJ). Most physician practice owners above those thresholds receive no QBI benefit. Lower-earning owners and associates should verify eligibility with a CPA each year.
