EOFY Property Investor Checklist: 7 Tax Deductions Most Australians Miss

Disclaimer: This article contains general information only and does not constitute financial or tax advice. Property investors should consult a registered tax agent or accountant for advice specific to their circumstances.

With 30 June approaching faster than most landlords would like to admit, there is a familiar scramble underway across Australia. Shoeboxes of receipts emerge from kitchen drawers. Bank statements get downloaded in bulk. Accountants brace for the annual inbox flood.

Here is the uncomfortable truth: even diligent property investors regularly leave money on the table at tax time — not through carelessness, but simply because some legitimate tax deductions are easy to overlook.

The ATO allows rental property owners to claim a broad range of expenses against their rental income, yet research consistently shows that investors under-claim in several key categories. With 2.3 million Australians owning investment properties, the collective value of missed deductions runs into hundreds of millions of dollars each financial year.

This comprehensive guide and EOFY checklist covers seven tax deductions that commonly slip through the cracks, along with practical guidance on how to capture and track them properly before the end of the financial year closes.

Why Savvy Property Investors Prepare Early for the Financial Year End

Preparing your investment property tax deductions well before 30 June gives you time to review rental income, organise receipts, and ensure nothing is missed. Many investors wait until the last minute and end up leaving thousands of dollars in deductions unclaimed.

A proactive approach means reviewing your property portfolio, checking your depreciation schedule, and confirming all property expenses are categorised correctly. This is an ideal time to speak with your accountant and assess your overall tax position for the year ahead.

1. Depreciation on Plant and Equipment — A Common Missed Deduction

Why it is missed: Depreciation is not a cash expense — you do not write a cheque for it — which means it does not show up on a bank statement. Without a formal depreciation schedule, most property investors simply do not know what they are entitled to claim as tax deductions.

Under Australian tax law, investors can claim depreciation on the decline in value of plant and equipment assets within an investment property. These items include ovens, dishwashers, air conditioning units, hot water systems, carpet, blinds, and curtains.

A qualified quantity surveyor can prepare a tax depreciation schedule that identifies every eligible asset and calculates the allowable deduction for each year of ownership. The depreciation schedule itself is also tax deductible.

For investment properties purchased after 9 May 2017, note that second hand assets depreciation rules changed. Only brand-new assets in a property you have used for investment purposes since it was new are claimable. Your qualified quantity surveyor or accountant can confirm what applies to your specific property.

Tip: If you have not organised a depreciation schedule yet, doing so before 30 June means you can claim the schedule cost this financial year. This is a great time to get it done and maximise your tax deductions.

2. Capital Works Deductions (Division 43)

Why it is missed: Many investors confuse capital works with capital improvements and assume they cannot be claimed until the property is sold. This is one of the most common mistakes among property investors.

Capital works deductions cover the structural elements of a building — walls, roofing, flooring, internal partitions, fittings, and any renovations or capital improvements made to the investment property. The ATO generally allows a 2.5% deduction per year on eligible construction costs, claimable over 40 years and depreciated over time.

A qualified quantity surveyor report is the standard mechanism. If your investment property was built after 16 September 1987 or has undergone renovations since then, there are likely tax deductions available you have not yet claimed.

3. Loan Interest and Borrowing Costs

Why it is missed: These are one-off costs paid years ago — property investors often forget they exist, let alone that they can be claimed over time as tax deductions.

Borrowing costs — including loan establishment fees, mortgage broker fees, lenders mortgage insurance, and title search fees — can be deducted against your rental income. If total borrowing costs exceed $100, they must be spread across five years or the loan term, whichever is shorter. If they are $100 or under, you claim them in full in the financial year they were incurred.

The loan interest on your investment loan is typically your largest deduction. Ensure you claim the full interest portion each year. If you refinance, new borrowing costs become claimable and any unamortised costs from the previous loan can be claimed immediately.

Only the interest portion of your loan repayments is deductible — principal repayments on your investment loan are not tax deductible but still represent a cash outflow that affects your cash flow positive position.

4. Repairs vs Capital Improvements: Getting the Distinction Right

Why it is missed: The line between eligible repairs, maintenance, and capital improvements is a common source of confusion — and getting it wrong means either missing out on an immediately deductible expense or incorrectly claiming something that should be depreciated over time.

Repairs and maintenance (for example, fixing a leaking tap, repainting faded walls, replacing a broken fence paling, or restoring damaged carpets) are generally deductible in full in the financial year they are incurred.

Capital improvements (for example, adding a new deck, replacing an entire fence with a different structure, or installing a new kitchen) must be depreciated over time as capital works.

Keep detailed records of each expense, including invoices that describe the work performed. Note whether the work was to restore something to its original condition (likely a repair) or created something new or better (likely a capital improvement).

Tip: If you are unsure of the classification, flag the item for your accountant before lodging your tax return — reclassifying after the fact is possible but adds complexity.

5. Home Office Expenses for Property Management Activities

Why it is missed: Self-managing landlords — and even those who actively manage their portfolio alongside a property manager — often do not realise that time spent administering their investment properties from home may entitle them to a home office deduction.

Activities like reviewing tenancy agreements, corresponding with property managers, preparing lease renewals, reconciling rental income, and maintaining expense records are all investment-related administration tasks.

The ATO fixed rate method (currently 70 cents per hour) requires a record of hours spent on eligible working activities from home. Keep a running log — even a simple spreadsheet — as the ATO expects substantiation. This approach can save time and maximise your tax deductions.

6. Travel Expenses (With Important Limitations)

Why it is missed: The rules changed significantly from 1 July 2017, and some property investors have not updated their understanding.

From the 2017-18 financial year onward, travel expenses to inspect, maintain, or collect rent from a residential rental property are no longer deductible for individual investors. This was a significant legislative change that many investors are not aware of.

Travel costs directly related to your property management activities may still be claimable in some limited circumstances. Professional advice from your accountant is essential to assess your eligibility and ensure you stay compliant.

7. Insurance Premiums — Often Overlooked Tax Deductions

Why it is missed: Insurance premiums are often paid annually, automatically charged to a credit card or separate account, and forgotten by tax time.

Insurance premiums for your investment property are fully deductible in the financial year they are incurred. This includes landlord insurance, building insurance, contents insurance, and public liability insurance relating to the rental property. Insurance costs can add up to thousands of dollars across a property portfolio, making them significant tax deductions.

Set up a separate account or credit card for investment property expenses where possible. At minimum, tag all property-related expenses in your banking app or accounting tool at the time of payment, not retrospectively at EOFY. Being organised throughout the year makes tax time straightforward.

Capital Gains Tax and Your Investment Strategy

Beyond annual tax deductions, property investors should also consider the capital gains tax implications of their investment strategy. When selling an investment property, capital gains are added to your taxable income. Holding the property for more than 12 months entitles you to a 50% CGT discount, which can significantly reduce the tax paid on any capital gains.

Understanding how capital gains tax interacts with your overall investment strategy and property portfolio is essential for long term planning. Your accountant can help you assess the best approach.

Council Rates, Property Management Fees, and Other Property Expenses

Several other property expenses are immediately deductible, including council rates, water charges, property management fees, letting fees, advertising costs, pest control expenses, and body corporate fees. Property management fees typically range from 5 to 10 percent of rental income and are fully deductible.

All management fees, council rates, and related expenses paid during the financial year should be included in your tax return. Ensure your property manager provides accurate reporting and rental income statements before you lodge.

Common Mistakes Property Investors Make at Tax Time

The most common mistakes include failing to claim depreciation, confusing repairs with capital improvements, not keeping adequate records, and forgetting insurance premiums. Savvy property investors review their complete list of property expenses and check every category before the end of the financial year.

Another common mistake is not claiming expenses incurred while the property is genuinely available for rent, even if it is temporarily vacant. As long as you are making genuine efforts to find a tenant, these expenses remain deductible.

The Bigger Picture: Record-Keeping Is Your Best Tax Strategy

The tax deductions above are legitimate and often substantial — but the Australian Taxation Office requires substantiation. That means invoices, bank statements, loan documents, and contemporaneous records. A deduction you cannot evidence is a deduction you cannot claim.

For property investors managing one investment property, manual spreadsheets might be manageable. For those with a growing portfolio of two, three, or more properties, the administrative burden compounds quickly.

Always consult a registered tax agent or accountant before lodging your tax return. PropBoss does not provide tax, legal, or financial advice.A depreciation schedule is a report prepared by a qualified quantity surveyor that outlines how much value your property and its contents lose over time, allowing you to claim that loss as a tax deduction.

Depreciation is categorized into two types: Capital works (Division 43), which covers the building structure, and Plant and equipment (Division 40), which includes removable items like appliances and fixtures.

If your property was built after 1987, you are likely eligible to claim capital works deductions, and even older properties may qualify for depreciation on renovations or fittings.

A depreciation schedule can help streamline the tax return process by providing your accountant with the necessary information to apply the correct deductions each year, reducing the need for guesswork.

The cost of obtaining a depreciation schedule is tax-deductible, and in many cases, the tax savings from the first year's deductions can cover the cost of the report.

Investors can prepay up to 12 months of expenses before the end of the financial year to bring the deduction into the current year.

Keeping detailed records of all property-related expenses and documents is crucial for maximizing tax deductions and ensuring compliance with the Australian Taxation Office (ATO).

Applying for a PAYG withholding variation with the ATO can help property investors manage cash flow by allowing them to receive tax deductions more frequently throughout the year instead of waiting for a lump sum at the end of the financial year.

It's important to start thinking about the next financial year by planning any renovations or repairs needed on your investment property before 30 June, as these costs can be claimed as deductions in the following tax return.

Property investors can claim deductions on rental income for expenses such as interest on loans, property management fees, council rates, insurance, and repairs/maintenance.

For properties purchased after May 2017, depreciation for second-hand assets is generally not available.

The interest portion of mortgage repayments is typically the largest deduction for property investors.

The ATO uses advanced data matching for 2.3 million records to cross-reference rental income and expenses.

Travel expenses related to residential rental properties are generally not deductible for most individual investors.

The Australian Taxation Office (ATO) categorizes tax deductions into expenses that can be claimed immediately and those that must be claimed over several years.

Borrowing expenses such as loan application fees and lender's mortgage insurance (LMI) are usually claimed over five years.

Council rates and water rates are ongoing statutory charges that the property owner pays.

Most repairs and general maintenance costs for investment properties can be claimed as tax deductions, but improvements cannot be claimed as repairs.

Initial repairs made to a property before it is rented out are not immediately deductible and must be added to the property's acquisition cost for capital gains tax purposes.

Expenses incurred for repairs that restore a property to its original condition are generally deductible, while expenses for improvements that enhance the property are not immediately deductible and must be depreciated over time.

Capital gains tax (CGT) is triggered at settlement, not at the contract signing, meaning the timing of the sale can affect your tax return.

Your main home (Primary Place Of Residence) is usually exempt from capital gains tax, but if it has been rented out, CGT may apply to part of the gain.

If you've sold another property or asset at a loss, you can use that loss to offset your capital gain, potentially reducing your CGT liability.

If you replace a section of damaged roof tiles with similar materials, this is considered a repair and is deductible, whereas replacing the entire roof with modern materials is classified as a capital improvement and must be written off over time.

Initial repairs made to fix damage that existed at the time of purchase are not immediately deductible; instead, they are considered part of the property's acquisition cost and can be added to the cost base for capital gains tax purposes.
