Doctors often face a more complicated tax picture than the average taxpayer. A physician may earn a salary from a hospital while also receiving independent contractor income, owning a medical practice, or providing telemedicine services. Each source of income can affect which expenses are deductible.
Understanding what doctors can write off on taxes starts with separating personal expenses from legitimate business costs. It also means knowing whether you are being paid as a W-2 employee, a 1099 contractor, or an owner of a medical practice.
Tax deductions can reduce taxable income, but the rules depend heavily on how your medical work is structured. Keeping accurate records throughout the year and working with an experienced CPA can help you claim available deductions without taking unnecessary tax risks.
Common Tax Deductions for Doctors
Physicians who operate a business or receive self-employment income can generally deduct ordinary and necessary expenses related to that work. Depending on the practice, deductible costs may include professional licensing, malpractice insurance, continuing education, office expenses, and qualifying business travel.
Your employment status matters. Most W-2 physicians cannot deduct unreimbursed employee business expenses on their federal returns. Current tax law disallows most miscellaneous itemized deductions that previously covered unreimbursed employee expenses. Self-employed physicians, on the other hand, may deduct qualifying expenses associated with their trade or business.
Avoid waiting until tax season to reconstruct your expenses. Keep receipts, invoices, mileage records, and business-purpose notes when transactions occur. Contemporaneous records provide stronger documentation if the IRS questions a deduction later.
Health Insurance Premiums and HSAs
Self-employed doctors may be able to deduct qualifying health insurance premiums as an adjustment to income. The deduction may cover eligible medical, dental, and vision insurance for the physician and qualifying family members. In general, the insurance plan must be established under the business, and the deduction is limited by earned income from that business. You generally cannot claim it for months when you were eligible for subsidized employer coverage.
A Health Savings Account (HSA) can provide another valuable tax benefit for physicians enrolled in an eligible high-deductible health plan. Contributions are generally deductible, earnings can grow tax-free, and qualified medical withdrawals are tax-free.
For 2026, the HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage.
Keep premium invoices and annual policy statements with your tax records. These documents help establish the amount paid and the periods your coverage was active.
Deductible Business Expenses for Medical Practices
Owning a medical practice creates a broader range of potential deductions because the practice can generally deduct ordinary and necessary costs of operating the business.
Rent paid for clinic or office space is usually a business expense. Utilities associated with the practice can also qualify. Wages paid to employees are generally deductible when they meet applicable compensation and employment-tax requirements.
One of the simplest ways to improve tax documentation is to keep business and personal transactions separate. Maintain a dedicated practice checking account and use a separate business credit card whenever possible. Clear financial separation makes bookkeeping easier and reduces the possibility of personal purchases being incorrectly recorded as business expenses.
Medical Equipment, Section 179, and Depreciation
Expensive medical equipment does not always have to be deducted gradually over many years. Section 179 may allow a medical practice to expense qualifying property during the year it is placed in service.
For tax years beginning in 2026, the maximum Section 179 deduction is $2.56 million. The deduction begins to phase out when qualifying Section 179 property placed in service exceeds $4.09 million. The deduction is also subject to taxable business income limitations.
Bonus depreciation provides another potential strategy. Current law generally provides permanent 100% first-year bonus depreciation for eligible property acquired after January 19, 2025.
The best method depends on your income and long-term tax strategy. Save purchase invoices and serial-number information for medical equipment and ask your CPA to verify income limitations before electing Section 179 treatment.
Qualified Business Deduction (QBI) for Physicians
Owners of qualifying pass-through businesses may be eligible for the Qualified Business Income deduction under Section 199A. In general, eligible taxpayers can deduct up to 20% of qualified business income, subject to several restrictions.
Medical services fall within the IRS definition of a specified service trade or business, or SSTB. That designation means a physician’s ability to claim the QBI deduction can be reduced or eliminated as taxable income rises.
For 2026, the QBI threshold is $403,500 for married couples filing jointly and $201,750 for most other returns. The applicable SSTB phase-out range extends to $553,500 for joint returns and approximately $276,750 for other filers.
Because practice structure can affect QBI planning, physicians should consider reviewing their entity structure with Custom Accounting CPA rather than assuming the deduction applies automatically.
Professional Development, Licensing, and Insurance Premiums
Professional costs required to maintain your medical career may qualify as business deductions when you are self-employed, or the expense is incurred by your practice.
CME registration fees may be deductible when the education maintains or improves skills needed in your existing profession. Medical licensure expenses should also be documented, along with board certification or recertification costs associated with your current practice.
Malpractice insurance premiums are generally a business expense when the policy covers professional activities associated with the medical business.
Keep invoices and payment records for these expenses instead of relying solely on bank or credit card statements. The invoice explains what you purchased, while the payment record establishes that the expense was actually paid.
Home Office Deduction for Telemedicine and Admin Work
A home office may qualify for a deduction when a self-employed doctor regularly uses a specific portion of the home for business. In most situations, the space must meet both the regular-use and exclusive-use tests.
A physician who conducts substantial administrative or management work at home may also meet the principal-place-of-business requirement when there is no other fixed location where those activities are substantially performed.
Self-employed physicians can choose between the simplified and actual-expense methods for a qualifying home office. Under the simplified method, the IRS allows $5 per square foot for up to 300 square feet, resulting in a maximum potential deduction of $1,500.
If you use the actual-expense method, calculate the percentage of the home devoted to qualified business use. That percentage can then help determine the allowable portion of certain indirect household expenses.
Vehicle and Travel Deductions
Self-employed physicians who drive for legitimate business purposes may be able to deduct vehicle expenses using either the standard mileage method or the actual-expense method.
The mileage method applies the IRS business mileage rate to qualifying miles. The actual method instead calculates deductible costs based on the business-use portion of eligible vehicle expenses.
For 2026, the IRS initially set the business mileage rate at 72.5 cents per mile. A midyear adjustment increased it to 76 cents per mile for qualifying business travel beginning July 1, 2026.
Regardless of the method used, maintain a contemporaneous mileage log showing dates, destinations, mileage, and business purpose. Normal commuting generally does not qualify.
Travel for qualifying CME may also be deductible for self-employed physicians when the trip has a legitimate business purpose. Save registration records and travel documentation to establish why the trip was connected to your medical work.
Retirement Contributions and Tax-Advantaged Accounts
Retirement planning can provide significant tax advantages for physicians with self-employment or practice income.
A SEP-IRA allows an employer to make contributions based on eligible compensation. For 2026, SEP contributions are generally limited to the lesser of 25% of employee compensation or $72,000, although calculating the limit for a self-employed owner requires an additional adjustment.
A Solo 401(k) can be attractive to a physician who owns a business with no eligible employees other than a spouse. The owner participates as both employee and employer. The 2026 employee elective-deferral limit is $24,500, while the overall defined-contribution limit can reach $72,000 before applicable catch-up contributions.
High-income practice owners may also consider a defined benefit plan. Contributions are actuarially calculated and can potentially be much higher than those permitted under standard defined-contribution plans.
When eligible, maximizing an HSA can add another tax-advantaged savings tool to the physician’s overall financial plan.
Common Audit Triggers and Recordkeeping Best Practices
No deduction automatically causes an audit, but weak documentation can create problems when a tax return is examined.
Large business deductions without supporting receipts deserve particular attention. Vehicle deductions should have mileage logs, while significant equipment purchases should have invoices. Payroll records must also reconcile with the tax forms filed for employees.
A separate business credit card can simplify this process by keeping practice purchases out of personal transaction histories. You should still save supporting documentation because a credit card statement alone may not establish the exact business purpose.
Year-round bookkeeping is especially important for physicians who own practices. Monthly reconciliation can identify missing transactions before they turn into larger tax problems. Payroll should receive the same attention because late deposits, classification errors, and reporting discrepancies can carry separate penalties.
Good tax planning is not simply about finding more deductions. It is about building records that show why legitimate deductions belong on the return.
Work With a Financial Advisor From Custom Accounting CPA
Physicians often have tax considerations that extend far beyond filing an annual return. Practice ownership, multiple income sources, retirement contributions, investment activity, and changing compensation can create opportunities for year-round planning.
Custom Accounting CPA can help you develop a proactive tax strategy instead of waiting until filing season to find out what you owe. Year-round tax reduction services can identify potential deductions and planning opportunities while there is still time to act.
