Between managing complex patient cases, staying on top of endless CPD requirements, and keeping up with the relentless pace of a hospital or private clinic, your mind is constantly working at 100 miles an hour. It’s no surprise that the business side of being a doctor—the tax structures, the deductions, and the cash flow—often gets pushed to the back burner.
When doctors sit down with a specialist medical accountant, the conversation usually moves past basic bookkeeping very quickly. Doctors want to know how to protect their hard-earned money, stay compliant, and stop overpaying tax.
If you’ve been wondering about your own finances, you aren’t alone. Here are the real, common financial and tax questions practising doctors ask, stripped of the dense accounting jargon.
Structure & The “Spouse Tax” Dilemma
“Should I set up a Company or a Trust for my private work?”
It’s the classic dinner-party question among registrars and consultants. The answer depends heavily on how you work. If you are doing private consulting or contract work, a company or discretionary trust can offer excellent asset protection. However, setting up a complex structure doesn’t automatically mean you pay less tax.
“Can I split my medical income with my partner to drop a tax bracket?”
This is where the Australian Taxation Office (ATO) draws a very sharp line. Because your income is generated by your highly specialized personal skill and qualifications, it is classified as Personal Services Income (PSI). The ATO generally prevents you from “assigning” this income to a non-medical spouse to lower your tax bill. While you can’t split your medical earnings, you can often use structures to split investment income or run a genuine service entity. Getting this wrong can lead to painful penalties.
Claiming What’s Yours: Deductions & Self-Education
“What can I actually claim back at tax time?”
Doctors have some of the highest professional out-of-pocket costs of any industry. Fortunately, if an expense is directly related to earning your income, it is generally deductible. This includes:
- Professional memberships: Your Australian Medical Association (AMA) fees, AHPRA registration, and medical board dues.
- Insurances: Your medical indemnity insurance premium is a major (and completely deductible) expense.
- The tools of the trade: Stethoscopes, surgical loupes, reference books, and the laptop or tablet you use for patient notes.
- Workwear: The cost of purchasing and laundering targeted protective clothing, scrubs, or uniforms with a clinic logo.
“How do I claim international conferences and courses without triggering an audit?”
Medical training never stops, and flights, accommodation, and registration fees for a conference or college exam add up quickly. If you travel for a conference, you can claim the costs—but you must be careful if you tag a holiday onto the end of the trip. If a trip is 60% conference and 40% holiday, your flights and accommodation must be apportioned. Keeping a meticulous travel diary and saving every digital receipt is non-negotiable here.
The Commute: Motor Vehicle Claims
“Can I claim my travel between hospitals?”
As a general rule, the ATO views your daily commute from home to your principal place of work (like your primary hospital) as private travel, meaning it’s not deductible.
However, if you are a doctor who moves between multiple campuses, drives from the hospital to a private consulting room, or visits patients at their homes, those specific legs of the journey are deductible.
“Logbook vs. Cents-per-Kilometre: Which is better?”
If you only drive a few hundred kilometers a year for work, the cents-per-kilometre method (which allows you to claim up to 5,000 km without a logbook) is simple and efficient. But if you are regularly driving between clinics or hospitals, keeping a valid 12-week logbook to calculate your actual business-use percentage almost always yields a significantly higher tax deduction.
Avoiding the “Tax Shock” & Super Slips
“Why did I get hit with a massive, unexpected tax bill this year?”
This is the classic trap for doctors transitioning from a salaried hospital payroll to private practice or contract billings. When you are employed, your tax is withheld automatically. When you bill as a sole trader or contractor, you receive the gross amount.
If you don’t set aside 30% to 45% of that private income, you will face a major cash-flow shock when you lodge your return. Furthermore, the ATO will then enter you into the Pay As You Go (PAYG) instalment system, requiring you to pay your next year’s tax in quarterly estimates in advance.
“Could I accidentally be breaching my superannuation cap?”
If you work a hybrid schedule—such as a staff specialist role at a public hospital alongside a couple of sessions at a private clinic—you might have multiple employers paying superannuation into your account. The annual cap on pre-tax (concessional) super contributions is strictly capped. If your combined employer contributions quietly slide over that limit, you can face unexpected tax penalties.
The Bottom Line
Your financial landscape changes rapidly as you progress from a resident to a registrar, and finally to a consultant or practice owner. The tax rules governing medical professionals are highly specific, and the ATO keeps a very close eye on the healthcare sector.
Partnering with an accountant who specializes exclusively in medical professionals ensures you aren’t leaving money on the table, while keeping your financial structure fully compliant.
