Rental Property Tax Guide: Deductions, Depreciation & Negative Gearing

A rental property can be one of the most tax-effective investments in Australia — but only if you understand what the Australian Taxation Office (ATO) will and will not let you claim. Rental deductions are also one of the areas the ATO scrutinises most closely, with reviews regularly finding errors in a large share of investor returns. This guide walks Melbourne landlords through the essentials: the deductions you can claim, how depreciation works, what negative gearing really means, and what happens to tax when you eventually sell.

When you rent out a property at market rates, the rent you receive is assessable income, and the costs of earning that income are generally deductible. The catch is in the detail — the timing of a deduction, whether a cost is a repair or an improvement, and how you apportion expenses all change the result. Get the framework right and the rest follows.

1. What you can claim each year

Ongoing expenses incurred while the property is rented or genuinely available for rent are usually deductible in the year you pay them. Common examples include:

• Interest on the loan used to buy the property (but not repayments of the principal).
• Council rates, land tax and water charges.
• Property management and letting fees charged by your agent.
• Landlord insurance, body corporate fees and cleaning or gardening.
• Repairs and maintenance that restore the property to its original condition.

You generally cannot claim costs that relate to your own private use, expenses your tenant pays, or the costs of buying and selling the property itself — those form part of the capital gains calculation instead.

2. Repairs vs improvements — a costly distinction

This is where many investors slip up. A repair fixes wear and tear or damage that happened while the property was rented — replacing a few broken roof tiles, fixing a leaking tap — and is deductible immediately. An improvement makes the property better than it was, or replaces something entirely (a whole new kitchen, a new fence, a full re-roof). Improvements are capital works, not instant deductions, and are claimed gradually through depreciation. Repairs made as soon as you buy the property, before it has earned any rent, are usually treated as capital too.

3. Depreciation: claiming the building and the fittings

Depreciation lets you deduct the declining value of the property over time, and it splits into two parts. Capital works (Division 43) covers the building structure — typically 2.5% of the construction cost each year for up to 40 years where construction started after 15 September 1987 (4% for residential construction started between 18 July 1985 and 15 September 1987). Plant and equipment (Division 40) covers removable assets such as ovens, carpet, blinds and air conditioners, depreciated over their effective life. Note that since 2017, deductions for previously used plant and equipment in second-hand residential properties are restricted — broadly, you can only claim Division 40 on assets you buy new. A qualified quantity surveyor’s depreciation schedule is the standard way to capture these deductions correctly, and its cost is itself deductible.

4. Negative gearing explained

A property is negatively geared when its deductible expenses — chiefly loan interest — exceed the rent it produces, creating a loss. In Australia that net rental loss can generally be offset against your other income, such as your salary, reducing your overall tax bill for the year. Negative gearing is a cash-flow strategy, not free money: you are still out of pocket each year and are relying on long-term capital growth to come out ahead. A positively geared property, by contrast, produces a profit that is taxable but puts cash in your pocket now. Which suits you depends on your income, risk appetite and goals — worth modelling before you buy.

5. Records, apportionment and CGT when you sell

Keep every document: loan statements, agent summaries, invoices, and the depreciation schedule. If you use the property privately (for example a holiday home let out part of the year), or you co-own it, you must apportion income and deductions accordingly. When you sell, capital gains tax applies to the profit — but if you have held the property for more than 12 months as an individual, you generally qualify for the 50% CGT discount. Remember that capital works deductions you claimed reduce your cost base, which increases the gain on sale, so the two sides need to be reconciled. Planning the sale year and timing can make a meaningful difference to the final tax.

Make your property work harder at tax time

The difference between an average and an excellent rental tax outcome usually comes down to two things: claiming every legitimate deduction (especially depreciation, which many investors miss entirely) and correctly classifying repairs, improvements and capital costs. Because the ATO watches this area closely, accuracy matters as much as maximising the claim. A Melbourne accountant who deals with property investors can set up a depreciation schedule, keep your apportionment defensible, and plan around the eventual sale.
