You bought an investment property to build wealth. Tax deductions are how you keep more of that wealth along the way.
The Australian Taxation Office allows property investors to claim deductions for expenses incurred in relation to a rental property, provided the property is rented out or genuinely available for rent. Some deductions you claim immediately. Others you spread across multiple years. And some expenses you cannot claim at all.
This guide covers every deduction category, how to treat each one correctly, and the mistakes that attract ATO attention.
How Rental Property Deductions Work
The ATO groups rental expenses into three categories:
- Expenses you can claim immediately in the income year you incur them (for example, interest on loans, council rates, repairs and maintenance, and depreciating assets costing $300 or less)
- Expenses you claim over several years (for example, capital works, borrowing expenses, and the decline in value of depreciating assets that cost more than $300)
- Expenses you cannot claim (for example, personal expenses, certain capital costs, and the purchase of second-hand depreciating assets after 9 May 2017)
Getting each expense into the right category matters. Claiming a capital expense as an immediate deduction is one of the fastest ways to trigger an ATO review.
Deductions You Can Claim Immediately
These are the expenses you deduct in full in the financial year you pay them.
Loan Interest
This is typically the single largest deduction for property investors. You can claim all interest charged on a loan used to purchase your investment property. According to Aussie, property investors can claim all interest paid on their mortgage as tax deductible, including annual and monthly loan maintenance fees, offset account fees, and withdrawal fees for redraw facilities.
If you have a split loan (part investment, part personal), you must apportion the interest based on how much of the principal was used for each purpose. Interest on the personal portion is not deductible.
Property Management and Agent Fees
Fees and commissions paid to your property manager, including letting fees, advertising for tenants, lease document expenses, statement fees, and bank charges. According to Property Tax Specialists, these are immediately deductible in the year incurred.
Council Rates, Water Rates and Land Tax
Council rates and water rates (including usage charges where you, not the tenant, are responsible) are deductible. Land tax is also deductible, though first-time owners need to lodge an initial land tax return with the Office of State Revenue in their state or territory.
Insurance Premiums
Landlord insurance, building insurance, contents insurance, and public liability insurance for the rental property are all immediately deductible.
Repairs and Maintenance
Repairs restore something to its original condition. The ATO and Aussie both draw a clear line: to qualify as a repair, the damaged item must be restored to its original condition. You cannot upgrade the item and call it a repair.
Examples of deductible repairs:
- Replacing broken glass in a window
- Fixing a leaking tap
- Repairing electrical faults
- Patching damaged plaster
Examples of improvements (not immediately deductible):
- Replacing timber fence panels with steel panels
- Replacing a window frame entirely when only the glass was broken
- Renovating a bathroom beyond its original condition
According to Property Tax Specialists, the ATO is particularly vigilant about expenses described as repairs when they are considered to be improvements. Repairs made immediately after purchasing a property to make it suitable for rental are considered capital in nature and cannot be claimed as an immediate deduction.
Body Corporate and Strata Fees
If your investment property is in a strata complex, body corporate fees and strata title charges are immediately deductible.
Pest Control, Cleaning and Garden Maintenance
Pest control, cleaning between tenants, gardening, and lawn mowing costs are all deductible in the year incurred.
Administration Costs
Stationery, phone calls, and internet usage related to managing your rental property. Postage for property management documents. Legal expenses for debt collection or tenant disputes.
Electricity and Gas
Where you (not the tenant) are responsible for covering utility costs, these are deductible. The ATO specifies you cannot claim deductions for water or electricity usage charges borne by your tenants.
Deductions You Claim Over Several Years
These expenses are spread across multiple income years rather than claimed in one hit.
Borrowing Expenses
The costs of taking out your investment loan are claimed over five years (or the loan period if shorter than five years). According to Property Tax Specialists, claimable borrowing expenses include:
- Loan application fees
- Lender's legal expenses
- Title search fees
- Lender's mortgage insurance (LMI)
- Stamp duty on the mortgage (not on the property purchase)
- Mortgage registration fees
Depreciation (Decline in Value of Depreciating Assets)
The wear and tear on assets within your property (carpets, appliances, blinds, air conditioning units) can be claimed as a non-cash deduction over their effective life. Assets costing $300 or less can be written off immediately in the year of purchase.
For assets costing more than $300, you claim the decline in value over their effective life using either the prime cost or diminishing value method.
Important restriction: The ATO states you cannot claim a deduction for the decline in value of certain second-hand depreciating assets against your residential rental property income, unless you are using the property in carrying on a business or you are an excluded entity. This rule applies to second-hand assets acquired after 9 May 2017.
Capital Works Deductions
The cost of constructing the building itself (or structural improvements) is deductible at 2.5% per year over 40 years. According to Property Tax Specialists, you can generally claim 2.5% of the construction cost of your investment property per year from the time it was built, for 40 years.
This applies to the building structure, not to removable fixtures and fittings (those fall under depreciation). A quantity surveyor prepares the depreciation schedule that separates these two categories.
Quantity Surveyor Fees
The cost of engaging a quantity surveyor to prepare your tax depreciation schedule is itself a deductible expense, according to Property Tax Specialists.
What You Cannot Claim
Some expenses are specifically excluded. Claiming them is a red flag.
Acquisition and disposal costs. The ATO explicitly states you cannot claim deductions for the costs of acquiring or disposing of your rental property, including the purchase price, conveyancing costs, stamp duty on the property, and buyer's agent fees. These form part of the cost base for capital gains tax purposes.
Travel expenses. You cannot claim travel expenses to inspect, maintain, or collect rent for your residential rental property, unless you are using it in carrying on a business or you are an excluded entity. The ATO includes the costs of travel, meals, and accommodation related to the property in this restriction.
Expenses when the property is not genuinely available for rent. If you use the property for personal purposes, you cannot claim deductions for that period. Expenses must be apportioned if the property has mixed use during the year.
Expenses borne by tenants. You cannot claim deductions for expenses you do not actually incur, such as water or electricity usage paid by tenants.
Pre-purchase inspection costs. Travel expenses to inspect a property before you buy it are not deductible.
Seminars about finding a property. The ATO states expenses for rental seminars about helping you find a rental property to invest in are not deductible. However, according to Property Tax Specialists, you can claim the cost of attending property investment seminars provided they relate to operating or maximising the return on properties you currently own.
Apportionment: When You Can Only Claim Part of an Expense
The ATO requires you to apportion expenses if any of the following apply:
- Your property is only rented or available for rent for part of the year
- You use the property for private or personal purposes for part of the year
- You only rent part of the property
- You rent the property at less than market rates
- You use your investment loan for private purposes
Apportionment is typically calculated using a time-based method (the proportion of days the property was rented versus not) or an area-based method (the proportion of the property used to earn income).
One exception: expenses that relate solely to renting the property, such as advertising for tenants and real estate agent commissions, are fully deductible regardless of the rental period.
The ABN Rule Most Investors Miss
If you pay a contractor for work on your rental property and they do not provide an Australian business number (ABN), you may need to withhold 47% of that payment and remit it to the ATO. According to the ATO, if you do not withhold from payments to a contractor who does not provide an ABN, you may not be able to claim a deduction for those expenses.
Always get a tax invoice with an ABN for every contractor payment. No ABN, no deduction.
Negative Gearing and How Deductions Reduce Your Tax
If your total rental expenses exceed your rental income, the property is negatively geared. That loss can be offset against your other income (salary, wages, business income), reducing your overall tax bill.
According to the ATO, you can claim deductions for rental expenses against your rental and other income, such as salary, wages, or business income.
If your rental income exceeds expenses, the property is positively geared, and that surplus forms part of your assessable income.
Understanding where your property sits on this spectrum matters because it determines whether your deductions reduce your tax bill or simply reduce your taxable rental profit. Either way, you want to claim every legitimate deduction. The difference between a well-claimed and poorly-claimed tax return can be thousands of dollars a year across a portfolio.
Common Mistakes That Attract ATO Attention
Claiming improvements as repairs. This is the most common error. If the work improves the property beyond its original condition, it is a capital improvement and must be depreciated over time, not claimed immediately.
Not apportioning for private use. If you use the property yourself for even a few days a year, you must reduce your deductions proportionally.
Claiming initial repair costs as immediate deductions. Repairs made to a property immediately after purchase to make it rentable are capital in nature. They form part of the property's cost base, not an immediate deduction.
Paying contractors cash without an ABN. As the ATO example illustrates, failing to obtain an ABN and withhold appropriately can mean losing the deduction entirely.
Claiming on vacant land. If your property is considered vacant land under the vacant land provisions, you generally cannot claim deductions for holding costs incurred before the property can be occupied, according to the ATO.
Getting Your Deductions Right From Day One
The difference between a good tax outcome and a bad one often comes down to record keeping. Keep receipts for every expense. Separate investment loan accounts from personal ones. Get a depreciation schedule from a qualified quantity surveyor in your first year of ownership.
If you want to understand how deductions fit into your broader investment strategy, including how rental yield and negative gearing interact, or how rentvesting changes your tax position, these are conversations worth having before you buy, not after.
