This article is general information only and does not constitute financial, tax or legal advice. Deductibility rules are complex, change over time and depend on your individual circumstances.

Most property investors know that rental property expenses are generally deductible. Far fewer have a reliable system for capturing those expenses throughout the year. The result is that at EOFY they end up reconstructing a year's worth of transactions from memory, bank statements and email — and they miss things.
This guide covers the main categories of deductible rental expenses and the practical approaches for tracking them. It is not an exhaustive tax guide — your accountant is the right person to confirm deductibility for specific items — but it will give you a clear framework for what to capture and how.
The key principle: immediately deductible vs capital
Before tracking expenses, it is worth understanding the most important distinction: whether an expense is immediately deductible in the year it is incurred, or whether it is a capital expenditure that must be depreciated over time.
Generally, a repair that restores the property to its original condition is immediately deductible. An improvement that adds value, extends the life of the property or changes its character is a capital item — it is written off over time via depreciation, not claimed in full in the year of purchase.
This distinction is genuinely difficult in some cases. Replacing a broken hot water system with an identical model is a repair. Replacing it with a solar system is an improvement. Replacing rotting floorboards with the same material is a repair. Upgrading to a different material is an improvement. When in doubt, record the expense with full details and discuss with your accountant.
Common categories of deductible expenses
The following are the main categories investors typically encounter. This is a general guide only — the ATO guidance and your accountant are the definitive sources for your specific situation.
Borrowing costs and interest
- Interest on the investment property loan.
- Loan establishment fees (amortised over the loan term or five years).
- Ongoing account-keeping or annual fees on the investment loan.
- Mortgage insurance premiums (where applicable and deductible — confirm with your accountant).
Property management costs
- Management fees charged by your property manager.
- Letting fees for finding a new tenant.
- Lease renewal fees.
- Advertising costs for finding tenants.
Holding costs
- Council rates and land tax (where applicable).
- Water and sewerage rates.
- Body corporate levies (excluding special levies for capital works — confirm deductibility).
- Landlord insurance and building insurance premiums.
Repairs and maintenance
- Plumbing repairs, electrical repairs and general maintenance.
- Painting and restoring to original condition.
- Gardening, lawn mowing and routine cleaning.
- Pest control and security system maintenance.
Professional and administrative costs
- Accountant fees for preparing your investment property tax return.
- Quantity surveyor fees for preparing or updating a depreciation schedule.
- Legal expenses for tenancy matters (not the original property purchase).
- Stationery and bookkeeping software related to your investment property.
What makes a record useful to your accountant
Not all expense records are equal. A bank statement line that says "Transfer $450" is less useful than an invoice that shows the date, the supplier, the property address, what was done and the amount. The more detail in the original document, the better.
For every deductible expense, you should be able to answer: When was it paid? Who was it paid to? What property does it relate to? What was it for? Can you produce a receipt or invoice?
Keep digital copies of all receipts and invoices — paper fades and is easily lost. Store them attached to the property they relate to, not in a general "receipts" folder, so you can find them quickly when they are needed.
Approaches to tracking expenses
There is no single right way to track investment property expenses. Here is an honest assessment of the most common approaches:
Dedicated bank account for each property
Works well: All income and expenses flow through a single account, making reconciliation straightforward and separation from personal finances clean.
Watch out for: Requires discipline to use it exclusively for the property and to avoid co-mingling funds.
A separate credit card for property expenses
Works well: Creates a clear record of property-related spending. Monthly statements provide a built-in audit trail.
Watch out for: Interest on the credit card balance is not deductible unless the card is used solely for the investment property.
Spreadsheet with manual entry
Works well: Free and flexible for small portfolios.
Watch out for: Manual entry introduces errors. No document storage. Becomes unworkable across multiple properties. Requires re-creation at tax time.
Portfolio tracking software
Works well: Expenses are categorised and stored against each property as they occur. Documents can be attached. Reports are available on demand, not just at EOFY.
Watch out for: Requires an upfront setup investment and ongoing discipline to keep records current.
The one mistake that costs investors the most
The single biggest missed-deduction scenario is not a complicated tax rule — it is simply the expense that was paid but never recorded. A small repair paid in cash. An insurance premium auto-renewed on a card you stopped checking. An annual inspection fee buried in a long agent statement.
The fix is systematic: go through every bank account and credit card statement that was used for the property, line by line, at least once a quarter. Flag anything that relates to the investment property and check it against your expense records. This catches the things that would otherwise be lost.
How Akweno helps
Akweno records every expense against the property it belongs to, with category, date and amount. Upload a receipt and AI-assisted extraction reads the amount and date automatically. Your full expense history is always available for any property, any year — so at EOFY you are reporting what happened, not reconstructing it.
Reminder: This guide is general information only. Tax deductibility is complex and depends on your individual circumstances, ownership structure, jurisdiction and the specific nature of each expense. Always seek advice from a registered tax agent or accountant before making any tax or investment decisions.
