For doctors, a larger tax refund is not about stretching the rules. It is about making sure you claim legitimate expenses that are genuinely connected with earning your income, while avoiding claims that are private, reimbursed or poorly documented.

This matters because medical work often involves multiple sites, professional obligations, continuing education, equipment and administrative duties that do not fit neatly into a standard employee checklist. The right approach depends on whether you are employed by a hospital or practice, work as a locum, operate as a sole trader, or run your work through a more complex practice structure.

Start with the three tests for every deduction

Before adding an expense to your tax return, apply three simple questions:

  • Did you pay the expense yourself?

  • Was it incurred in earning your assessable income?

  • Do you have records that substantiate both the cost and its work-related connection?

An expense must also not be private, domestic or capital in nature. If an expense has both work and private use, only the work-related portion may be claimed. Where an employer, hospital, practice or another party reimburses the cost, you cannot also claim it as your personal deduction.

It is also worth separating the idea of a deduction from the idea of a refund. A deduction reduces taxable income. Whether this results in a refund, rather than simply reducing tax payable, depends on your overall income, tax already withheld, instalments paid and other items in your return.

Doctors who work under more than one arrangement should be particularly careful. The same expense may be deductible against employment income, business income, or partly against each, but the expense must not be claimed twice. Clear records showing which role, practice or income stream an expense relates to are essential.

Professional costs that doctors should review

Professional obligations create several common deduction opportunities, provided the cost relates to your current income-producing work and you paid it personally.

Registration, memberships and indemnity

Renewal costs for professional registration, practising certificates, memberships and accreditations may be deductible where they are required for you to work in your current field. The ATO’s guidance specifically includes registration for doctors as an example of an ongoing expense that can have the necessary connection with employment income.

The distinction between initial and ongoing costs matters. Costs incurred to obtain your initial registration or qualification so that you can begin practising are generally not deductible, because they put you in a position to earn income rather than being incurred while earning it.

Depending on your circumstances, review:

  • annual registration renewal costs;

  • professional college and association subscriptions;

  • union fees;

  • medical indemnity insurance and other insurance directly connected with your clinical work;

  • professional journals, medical publications and clinical reference materials;

  • subscriptions to work-related software, databases and digital tools.

For memberships, distinguish annual subscriptions from joining fees. Annual fees that relate to your current work may be deductible, while an initial joining fee may be capital in nature. Social club fees and costs with no direct connection to your work should not be included.

Equipment, instruments and consumables

Doctors may personally purchase tools and equipment that support their clinical duties. Depending on the role and workplace, this could include items such as a stethoscope, medical instruments, work-specific bags, computer equipment, software or reference materials.

The tax treatment depends on the item and how it is used. A lower-cost item may be immediately deductible where the applicable requirements are met. More substantial equipment is generally claimed over time through its decline in value. Where an item has private use, such as a laptop or mobile phone, the claim must be reasonably apportioned.

Keep the invoice, note the purchase date and record how you use the item. A simple note in your records can be very helpful later, particularly for equipment that is used across hospital work, private practice administration, study and personal life.

Travel and car expenses: separate deductible trips from commuting

Travel is an area where doctors can have legitimate claims, but it is also an area that deserves care. Ordinary travel between home and a regular workplace is generally private, even if you work unusual hours, live a long way from the hospital, take work home, or are called on to perform demanding duties once you arrive.

However, travel undertaken in the course of performing work may be deductible. Examples can include travel:

  • directly between two workplaces;

  • between a hospital, clinic, rooms or another work location during the day;

  • to visit patients or attend a work-related meeting away from your usual workplace;

  • to attend an eligible work-related conference, course or seminar;

  • for a locum engagement where the travel is part of carrying out the income-producing work, rather than simply travelling from home to a regular workplace.

Car expenses require an appropriate calculation method and supporting records. The available methods differ in their record-keeping requirements. A logbook-based approach requires a valid representative logbook and ongoing odometer records, while the cents-per-kilometre approach still requires you to be able to demonstrate how your work-related kilometres were calculated.

Parking fees and tolls may be relevant where they relate to deductible work travel. Parking fines, speeding fines and other penalties are not deductible, even if they arise while travelling for work.

A practical habit is to keep a contemporaneous travel diary. Record the date, the locations, the purpose of the trip and the kilometres travelled. This is far more reliable than trying to reconstruct a year of travel from memory at EOFY.

Continuing education can be valuable, but the connection must be clear

Medicine requires ongoing education, and many doctors incur significant costs for courses, conferences, examinations, workshops, subscriptions and clinical resources. These expenses can be deductible where the education maintains or improves the skills and knowledge required in your current work, or is likely to increase income from your existing employment activities.

Potentially deductible costs may include:

  • conference and seminar registration fees;

  • professional development courses;

  • clinical workshops;

  • textbooks and specialist publications;

  • stationery and study materials;

  • work-related travel to attend education;

  • accommodation and meals where you must travel and stay away from home overnight;

  • the work-related use of equipment and internet services used for eligible study.

The key question is not whether the course is useful or impressive. It is whether there is a sufficiently direct connection between the expense and the duties you were performing when you incurred it.

For example, a doctor undertaking training in a procedure, treatment area or clinical skill used in their present role may have a stronger basis for a claim than someone studying to move into an entirely new profession or speciality. A course that enables you to obtain new employment or change employment is generally not deductible. The ATO specifically uses the example of a nurse studying medicine to become a doctor as a course that leads to new employment rather than being sufficiently connected with the nurse’s current duties.

Repayments of study and training loans are not deductible. It is important not to confuse loan repayments with the underlying cost of genuinely work-related education.

Home office, phone and digital expenses

Many doctors complete reports, referrals, research, rostering, billing, correspondence, CPD and practice administration outside clinical settings. If you work from home to carry out genuine employment duties, you may be able to claim the work-related portion of additional running expenses you incur.

Depending on the method used and your actual circumstances, relevant expenses may include:

  • home and mobile internet;

  • mobile and home phone use;

  • stationery and office supplies;

  • electricity or gas for heating, cooling and lighting;

  • the decline in value of a desk, chair, computer, monitor or other work equipment;

  • repairs and maintenance for work equipment.

A claim must reflect additional costs caused by working from home, not ordinary private household expenditure. Items supplied by your employer or reimbursed by a practice cannot be claimed again personally. General household groceries, coffee, tea and similar domestic costs are not deductible simply because you work from home.

For doctors operating a sole trader practice from home, the position may be different from that of an employee undertaking occasional administration at home. A home that is genuinely used as a place of business can raise broader deduction and capital gains tax considerations. In particular, claiming occupancy costs for an area set aside for business may affect the tax treatment when the home is sold. This should be considered before making a claim, rather than after a future sale is underway.

Extra considerations for locums, contractors and practice owners

A doctor operating as a sole trader or contractor may incur expenses that an employed doctor does not. Where the expenditure is directly connected with carrying on the medical business, typical categories to review include practice service fees, professional indemnity costs, accounting and bookkeeping fees, business insurance, clinical consumables, software, advertising, merchant fees and administrative expenses.

A sole trader reports business income and expenses in their individual tax return. They cannot claim a deduction for money or assets they withdraw for personal use.

Business structure also matters. The deductibility of an expense may be straightforward, but the entity that incurs it must be the entity claiming it. A doctor who works through a company, trust or service entity should not assume that personally paid costs and entity-paid costs can be moved between tax returns without considering the legal and commercial arrangements.

Consider a generic example. A doctor works shifts at a public hospital, performs locum work through their own ABN and completes private practice administration from home. They pay their own registration renewal, professional membership, indemnity cover, clinical conference costs, mobile phone expenses and travel between several work locations. A well-prepared return would separate employment-related costs from business costs, exclude reimbursed expenses and commuting, apportion mobile and home-office use, and retain evidence for each claim. The result is not an inflated refund, but a return that properly reflects the costs of earning that doctor’s income.

Make record-keeping part of your routine

The strongest deductions are the ones you can explain and substantiate. Keep invoices, receipts, insurance schedules, membership notices, course documentation, travel records and notes showing how you calculated any work-related percentage.

Digital records are acceptable, provided they are clear, complete and accessible. For work-related expenses, the ATO expects records that demonstrate the amount paid, what the expense was for, when it was incurred and how it related to your income-producing activities.

It can help to establish a simple monthly process:

  • save receipts to a dedicated digital folder;

  • review bank transactions for work expenses;

  • update your car and travel diary;

  • record work and private use percentages for shared expenses;

  • keep evidence of reimbursements, so they are not claimed accidentally;

  • speak with your accountant before making significant purchases or changing your work structure.

A considered approach delivers the best result

Doctors often have valid deductions that are overlooked because their work spans clinical care, education, administration and multiple locations. Equally, claims for ordinary commuting, private clothing, meals during normal shifts, initial qualifications, fines and reimbursed expenses can create unnecessary risk.

The aim is to claim what you are entitled to, support it properly and make decisions with the full picture in mind. Ample Finance can help you review your deductions, organise records and understand the tax implications of your particular employment or practice arrangements.
