Physician Expense Deductions
A licensed Ontario CPA on what physicians can deduct, and the question that matters more than the list. Most physicians do not lose deductions by claiming the wrong things. They lose them by paying practice costs personally, from money that has already been taxed, and never routing them through the corporation that should have paid.
Quick Answer
A physician can generally deduct what was incurred to earn practice income: professional dues and licensing, CMPA fees, continuing medical education, insurance, staff wages, clinic overhead, equipment, medical software, professional fees, and the business portion of vehicle and home office costs where the conditions are met. But the list is the easy part. The two things that actually decide what you keep are who claims the expense, you or your corporation, and the fact that because most physician billings are HST exempt, the tax you pay on your own costs is generally not recoverable. Both are addressed below.
The Question Is Not What. It Is Who.
Physicians ask what they can deduct. It is the wrong question, or at least the second question, and asking it first is why the answer disappoints. The deductible list for a physician is not exotic and it is not a secret: professional dues, CMPA fees, education, insurance, staff, overhead, equipment, software, the business share of vehicle and home office. Almost every physician already knows most of it. What separates the physician who keeps those deductions from the one who does not is rarely knowledge of the list. It is whether the expense went through the entity that earns the income. If you have a professional corporation, the corporation earns the practice income and the practice costs belong to it. When you pay CMPA fees by direct debit from your personal chequing account, when a course goes on a personal credit card, when the phone bill has been coming out of your personal account since residency, those costs are being paid with money that has already been through your personal tax rate. The corporation, which should have paid them and deducted them, never saw them. Nobody claimed anything aggressive. The deduction simply evaporated, quietly, across twelve months.

Where the Expense Belongs
The same cost, three different physicians, three different answers.
| Your Situation | Who Claims Practice Expenses | The Main Risk |
|---|---|---|
| Incorporated, professional corporation | The corporation, because it earns the income | Paying practice costs personally and never reimbursing. |
| Self-employed associate, not incorporated | You, against practice income directly | No records to support the categories that get reviewed. |
| Employed physician | Heavily restricted. Limited categories only | Assuming self-employed rules apply. They do not. |
| Incorporated, paid a course personally | The corporation, via documented reimbursement | Paying it, claiming nothing, assuming it was handled. |
| Incorporated, spouse does the billing | The corporation, as a reasonable salary for real work | A salary where no work is performed. Closely examined. |
An employed physician is in a different world entirely. If you are an employee rather than self-employed, the deductions available to you are far narrower, and they generally require a signed T2200 from your employer certifying the conditions of employment. Whether you are an employee, a self-employed associate, or operating through a corporation is a question of fact, not a question of what the agreement calls you. Physicians frequently apply self-employed logic to an employment relationship and find out at review. Our medical clinic accounting page covers the associate question in more depth.
The Physician Expense List
What generally qualifies, and what to keep alongside it.
| Expense | Position | What Supports It |
|---|---|---|
| CPSO and licensing dues | Deductible. Belongs in the corporation where one exists | The invoice. Please route the payment through the corporation. |
| CMPA fees | Deductible. Most commonly paid personally by mistake | The invoice, and a corporate payment rather than a personal debit. |
| Continuing medical education | Deductible where it maintains skills for your practice | Receipt plus the program or agenda showing what it was. |
| Conference travel and accommodation | Deductible where the primary purpose is the education | Program, dates, proof of attendance. Personal days separated. |
| Professional insurance | Deductible as a practice cost | The policy and the invoice. |
| Staff wages | Deductible. Spouse only for work actually performed | Payroll records and a reasonable amount for the work done. |
| EMR, billing software, subscriptions | Deductible practice costs | Invoices. Frequently on a personal card and never claimed. |
| Medical equipment | Generally capitalized and deducted over time via CCA | Invoice and acquisition date. The year matters. |
| Scrubs and protective equipment | Deductible. Ordinary clothing is not | Receipts. The test is specialized equipment, not worn at work. |
| Business meals | Generally limited to 50% of the reasonable amount | Receipt plus who and why. The purpose must be real. |
| Accounting and legal fees | Deductible where incurred for the practice | The invoice. |
| Phone and internet | Business portion only. A reasonable split | A dedicated practice line is far cleaner than apportioning. |
The Two That Get Reviewed
Vehicle and home office account for a disproportionate share of the trouble, because both invite an optimistic view that feels reasonable at the time.
On the vehicle: the drive between your home and a regular place of work is personal. It does not become business because you were thinking about patients, carrying files, or on call. Travel between clinic sites during the day is generally business. When physicians actually log their driving, the business percentage is often materially lower than the one they had been using. The 2026 limits cap what a vehicle can produce regardless of what you paid: Class 10.1 passenger vehicles at $39,000 before tax, zero-emission Class 54 vehicles at $61,000, deductible lease costs at $1,100 per month before tax, and loan interest at $350 per month. There is also a persistent misunderstanding about the per-kilometre rates. The published rates of 73 cents for the first 5,000 kilometres and 67 cents thereafter for 2026 are a benchmark for reimbursing employees tax-free. A corporation or a self-employed physician generally deducts the business-use share of actual costs, supported by a log, not a flat rate applied to distance.
| 2026 Vehicle Limit | Amount | What It Means |
|---|---|---|
| Class 10.1 passenger vehicle CCA ceiling | $39,000 before tax | Paying more does not increase what you can claim. |
| Class 54 zero-emission vehicle ceiling | $61,000 before tax | A higher ceiling for qualifying electric and hydrogen vehicles. |
| Deductible lease cost | $1,100 per month before tax | Lease above it if you like. Deduct only to the cap. |
| Loan interest deduction | $350 per month | Interest above this on a vehicle loan is not deductible. |
| Per-kilometre allowance benchmark | 73 cents first 5,000 km, 67 cents after | An employee reimbursement benchmark, not a deduction method. |
| Operating benefit rate | 34 cents per kilometre | Applies where a corporate vehicle is available for personal use. |
On the home office: the conditions are narrower than physicians expect. Broadly the space must be your principal place of business, or used exclusively for the practice and on a regular and continuous basis for meeting patients. A room where you complete charts in the evening after a full day at the hospital is a harder claim than it feels like, because the hospital is where the practice happens. Where the claim is available, the portion must be reasonable and supportable rather than convenient.
The receipt and the reason, not the statement. A credit card statement proves an amount left your account. It does not prove what was purchased or how it related to the practice, and for the categories above that distinction is the whole claim. Where a claim cannot be supported it is denied, and the interest runs from the original due date rather than from the day the CRA raised the question. Please note that where a pattern of unsupported claims emerges, reviews tend to widen rather than stay narrow. See our healthcare CRA audits page.
Why Your HST Is Not Coming Back
This one costs physicians real money and almost nobody raises it. Most physician billings are exempt supplies, which is not the same as zero-rated, and the difference is the entire point. A business making exempt supplies generally cannot claim input tax credits on what it buys. So the HST you pay on clinic rent, on equipment, on supplies, on software, on your accountant, is not a recoverable tax sitting in a receivable somewhere. It is a real cost that stays with you. The practical consequence is that your deductible expense is the full amount you paid including the HST, not the pre-tax amount, and books set up as though the tax were recoverable both understate your expenses and misstate your position. It also means the tax-inclusive cost is the number that matters when you are comparing an equipment quote or a lease. Some services physicians provide are not exempt, and where taxable supplies exist the analysis changes, potentially bringing registration and partial input tax credits into play. That is worth checking rather than assuming. See our HST exempt healthcare services in Ontario.
What Physicians Actually Miss
Not the clever items. The ordinary ones, paid from the wrong account.
- CMPA fees on personal direct debit. Set up years ago, never revisited, never routed through the corporation.
- A course paid from a personal account. Deductible, corporate, and claimed by nobody because no one reimbursed it.
- The phone bill from residency. Still coming out of the personal account, still partly a practice cost.
- Subscriptions on a personal card. EMR add-ons, dictation, secure messaging. Small individually, not annually.
- HST recorded as recoverable. It is not, on exempt billings. The expense is understated by the tax.
- A vehicle percentage nobody logged. Usually optimistic, and the first thing asked for on review.
Does Incorporating Give You More Deductions?
No, and the expectation causes real disappointment. Broadly the same expenses are deductible whether you are incorporated or a self-employed associate. What a corporation changes is timing, structure and who claims what, not the length of the list. If the reason you are considering incorporation is a longer menu of write-offs, that reason does not survive contact with the facts, and there are better reasons that do. Please see our incorporation for doctors and medical professional corporation rules in Ontario. Where you are already incorporated and the practice is running, the year-end is where the expense position is actually settled. See our corporate tax planning for doctors.
Case Study: Nothing Aggressive, Nothing Claimed
A physician came to us convinced she was missing deductions and wanted to know what else she could be claiming. Her return was not aggressive and nothing on it was wrong. The problem was upstream. Her CMPA fees came out of her personal chequing account on a direct debit set up before she incorporated. Her college dues went on a personal credit card. Two conferences that year had been booked personally because that was where the travel points were. Her EMR add-ons and dictation subscription had never moved off the personal card either. Every one of those was a legitimate corporate expense, paid with money that had already gone through her personal tax rate, and claimed by nobody. We moved the recurring payments to the corporation, documented reimbursements for the year where support existed, and set the bookkeeping up so the tax-inclusive amounts were recorded properly against exempt billings. The figures here are illustrative of the work we do, not a specific client file. Healthcare Accounting →
