Here’s a question that catches plenty of doctors off guard: why did your accountant, who handles a plumber’s books beautifully, miss a deduction that your colleague down the corridor claimed without a second thought? The answer is rarely carelessness. Medicine runs on its own financial rules, and general accounting simply wasn’t built around them.
Medical accounting is a specialised branch of accounting that deals with how doctors, specialists, dentists and practice owners earn, structure and keep their money. It covers the same ground as any accounting work, such as tax returns, BAS and financial statements. But it layers in the quirks of Medicare billing, practice service agreements, health sector GST rules and professional costs that other industries never see.
How Does Doctors’ Income Actually Work?
A typical small business sells a product or a service and gets paid by the customer. A doctor’s income is rarely that simple. You might bulk bill and receive payment direct from Medicare, charge private fees, take a percentage of billings through a service agreement with a practice, or do all three in the same week.
Each stream has its own timing and paperwork. Medicare payments land on a different schedule from patient payments, so cash flow can look healthy on paper and feel tight in the bank. An accountant who understands medicine will track each source separately and won’t treat it all as one lump of revenue.
What Is a Service Agreement and Why Does It Matter?
Many GPs and specialists work inside a practice owned by someone else. The practice provides rooms, staff, equipment and administration, and in return takes a share of your billings, often somewhere between 30 and 40 percent. That arrangement sits at the centre of your tax position.
If it’s drawn up carelessly, you can end up paying for things you can’t claim, or claiming things the ATO doesn’t see as yours. A medical accountant will read the agreement closely, check what the fee actually covers, and make sure your records match. It’s boring paperwork until the day it saves you a very expensive argument.
Which Tax Rules Are Unique to the Medical Industry?
Most health services provided by registered practitioners are GST free, but not all of them are. Cosmetic work without a therapeutic purpose and certain third party reports can attract GST, and mixing these up leads to messy BAS lodgements. General accountants often apply one rule across the board.
Then there are the professional costs. Think AHPRA registration, medical indemnity insurance, college fees, continuing professional development, journals, conference travel and clinical equipment. Some of these are straightforward, others need careful apportionment, and a few get claimed wrongly every year. The list below shows where medical specific knowledge usually earns its keep:
- Splitting expenses between private, bulk billed and hospital work
- Handling locum shifts and on call payments across several entities
- Applying the personal services income rules to practice arrangements
- Planning around the extra 15 percent tax on concessional super contributions for higher earners
- Choosing between a trust, company or sole trader setup for a practice
Does a Medical Accountant Do More Than Tax Returns?
A good one does. Tax time is the smallest part of the job. The real value is in planning during the year, so decisions about buying equipment, hiring a nurse, taking on a second site or setting up an SMSF are made with the numbers in front of you.
Picture a GP who has just decided to hire a practice nurse. A general accountant might say yes, payroll is easy enough. A medical accountant will also look at whether the extra wages are covered by the new Medicare billings, how Single Touch Payroll and super obligations fit in, and what it does to your cash flow over the next six months.
How Do You Know If Your Accountant Understands Medicine?
Ask a few direct questions. Can they explain how your service fee is treated for tax? Do they know which of your services are GST free? Have they worked with other doctors in your specialty, and can they talk about the common mistakes they see?
Vague answers are a warning sign. If you want to see what specialist support can look like in practice, the accounting and taxation services for medical professionals page walks through the areas a medical focused firm typically covers. For day to day record keeping, the team also explains how bookkeeping for medical practices differs from standard bookkeeping.
What Should You Do Next?
Start by reading your last tax return and your service agreement side by side. Look for anything you don’t understand, any deduction you’ve never claimed, and any number that surprised you. That small exercise often shows whether your accountant is working from a medical playbook or a generic one.
If you’d like to go deeper, the business advisory support for doctors page explains how planning fits around the numbers. The free guides and books section is also worth a browse if you prefer to learn at your own pace.
Wrapping Up Your Next Move
Medical accounting differs from regular accounting because medicine itself is different. Your income comes from several places, your costs are specific to your profession, and your tax rules have exceptions that only show up when someone has seen them before. The right accountant treats your career as a financial story, not a set of receipts.
My recommendation is simple: have your structure and service agreement reviewed by someone who works with doctors every day. Even one conversation can reveal gaps you didn’t know existed. So when did anyone last look at your finances as a whole, rather than just once a year at tax time?
