When you run a private medical practice, the IRS allows you to reduce your taxable income by accounting for ordinary and necessary expenses that are directly tied to the operation of your business. Knowing which expenses are deductible can save you a substantial sum each year. The following is a thorough guide to the most common deductible expenses for medical professionals in private practice, plus practical tips for tracking and documenting them.

1. Office Lease or Rent

The rental cost of the space where you see patients is fully deductible. Whether you lease a private office or share a space with other professionals, you may deduct the portion of rent attributable to the area used for patient care, records, and office equipment. Retain a copy of the lease and a detailed log of the square footage allocated to medical services versus administrative tasks.

2. Utilities and Maintenance

All utilities—electricity, water, heating, air conditioning, internet, and phone services—that support your practice are deductible. If your office is at home, you can deduct a proportionate share of your home utilities based on the office area relative to the entire dwelling. Maintain monthly bills and a spreadsheet that tracks the proportion used for practice activities.

3. Office Supplies and Equipment

All items that directly support patient care are deductible. This covers exam gloves, syringes, bandages, medical instruments, computers, software, printers, and even decorative items that improve the professional ambiance. For larger acquisitions, such as an MRI machine or a high‑end computer system, you may need to capitalize the cost and depreciate it over multiple years. A simple inventory list with purchase dates and costs will make year‑end reporting easier.

4. Medical Malpractice Insurance

Malpractice insurance premiums are a typical deductible expense. Keep the policy documents and receipts. If you have multiple lines of insurance (e.g., general liability, professional liability, cyber‑security coverage), list each policy separately for clarity.

5. Professional Development and Continuing Education

Educational events like courses, conferences, seminars, and workshops that keep you current are deductible. The IRS requires that the education be related to your current practice and help you maintain or improve your professional skills. Keep certificates of completion, registration fees, and travel expenses (airfare, lodging, meals) tied to the event.

6. Professional Association Dues

Membership fees for national or state medical societies, specialty boards, or local medical associations are deductible. Log the association’s name, the fee paid, and the membership dates. These fees often supply valuable networking, continuing education, and advocacy resources.

7. Client or Patient Billing and Collection Costs

Fees paid to third‑party billing services, electronic health record (EHR) transaction fees, and credit‑card processing fees are deductible. Additionally, interest paid on revolving lines of credit used for practice cash flow is deductible. Keep invoices and statements that detail each transaction.

8. Employee Salaries, Wages, and Benefits

If you hire staff—nurses, medical assistants, receptionists, billing clerks, or office managers—the wages, payroll taxes, and benefits you provide are deductible. Keep payroll records, W‑2 forms, and benefit statements. If you provide health insurance or retirement plans for employees, those contributions are also deductible.

9. Health Insurance for Yourself

Self‑employed medical professionals can deduct the premiums paid for health insurance, including dental and vision, for themselves and their families. This deduction is taken on the first page of your tax return and is subject to specific income thresholds. Keep policy statements and payment receipts.

10. Transportation and Travel

Business mileage on your personal vehicle, as well as overnight travel for conferences, continuing education, or visiting other practices, can be deducted. Use the standard mileage rate (currently 65.5 cents per mile for 2024) or actual expenses, but you must keep a detailed log of dates, destinations, purpose, and miles driven. For lodging and meals, you can deduct 50% of meal costs and 100% of lodging when traveling for business.

11. Depreciation of Office Assets

Large assets such as a medical office building, a clinic room renovation, or specialized equipment can be depreciated over their useful life. The IRS provides depreciation schedules for different asset classes. Keep the purchase invoices and use IRS tables to calculate the annual depreciation deduction.

12. Legal and Accounting Services

Fees paid to attorneys for contract review, intellectual property protection, or dispute resolution, as well as to accountants for tax preparation and financial consulting, are deductible. Retain the invoices and a brief description of the services rendered.

Renovations that directly improve the functionality of your practice—such as installing a new examination room, upgrading the HVAC system, or adding a waiting area—are deductible as capital improvements. Document the project details, costs, and dates. Some improvements may qualify for Section 179 expensing or bonus depreciation, allowing you to deduct the full cost in the year of purchase.

15. Miscellaneous Expenses

Other ordinary and necessary costs can be deducted, including:

• General liability and worker’s compensation insurance
  
• Cleaning and janitorial services for the office
  
• Security systems or software solutions
  
• Uniforms or scrubs that are not deemed personal clothing
  
• Parking fees incurred at conferences or meetings

• Keep a detailed ledger for each expense category, including vendor name, date, purpose, and supporting receipts or invoices.

A CPA or tax advisor experienced in medical practice taxation can help you identify additional opportunities and ensure compliance.
