A rental property can look profitable on paper while creating a very different tax outcome at year-end. This property investor tax basics guide outlines the main tax areas Australian investors should understand before relying on rental income, claiming deductions or planning a sale. It is general information, not personal tax advice. Your circumstances, ownership structure and property use can materially change the result.
Property investor tax basics guide: start with rental income
Rental income is generally assessable income. That includes regular rent, rent paid in advance, payments from a tenant for breaking a lease, and insurance payouts that replace lost rent. If a tenant pays you for damage to the property, the treatment may depend on whether the payment is income in nature or relates to a capital repair. This is one reason clear records matter.
Income is declared according to your ownership interest. If two people own a property as joint tenants or tenants in common in equal shares, each typically reports half the income and half the allowable expenses. Where ownership shares differ, income and expenses are usually split in those legal proportions. A private arrangement to divide income differently will not normally override the title position.
The timing of expenses and income also matters. For most individual investors, income is generally recognised when received and expenses when incurred. However, the detail can become more complicated where there are rental arrears, insurance claims, refinancing or a property held through a trust or company.
What investors can generally claim
A deduction must have a sufficient connection to earning rental income. It must also not be private, capital in nature or specifically excluded. For a property genuinely available for rent, common deductible costs may include loan interest, property management fees, council rates, water charges, landlord insurance, advertising for tenants, body corporate levies, repairs, cleaning, pest control and some legal expenses connected with the tenancy.
The distinction between a repair and an improvement is particularly important. Repairing a damaged fence with a comparable replacement may be deductible in the relevant year. Replacing an entire worn-out asset with a better or substantially different asset may instead be capital expenditure. Capital costs are not usually claimed immediately, although they may form part of the property’s cost base for capital gains tax purposes or be claimed over time through depreciation rules.
Interest is often a major deduction, but it is not automatically deductible simply because a loan is secured against an investment property. The key question is how the borrowed funds were used. Interest on money used to buy, improve or maintain a rental property may be deductible to the extent the property is used to earn rent. If funds are redrawn for a holiday, a car or another private purpose, the loan must generally be apportioned. Refinancing does not remove that tracing requirement.
A property that is only rented for part of the year, or used privately at any point, requires the same discipline. Expenses may need to be apportioned for the period it was not genuinely available for rent, for below-market arrangements with family or friends, or for private use. Advertising alone does not always establish that a property was available for rent. The rental terms, condition of the home and whether tenants could realistically occupy it will all matter.
Depreciation is useful, but not always straightforward
Depreciation relates to the decline in value of eligible assets and capital works deductions for qualifying construction expenditure. A quantity surveyor’s tax depreciation schedule can help identify claimable amounts, particularly for investment properties with significant plant and equipment or eligible building works.
However, depreciation rules for second-hand residential properties have changed over time. Many investors cannot claim a deduction for the decline in value of previously used plant and equipment in a residential rental property, although there are exceptions. Capital works deductions also have separate rules, including limits based on construction dates and the nature of the work. Obtain advice before assuming a schedule will produce the same outcome for every property.
Negative gearing and taxable profit
Negative gearing occurs when allowable rental-property deductions exceed the rental income received. Subject to the relevant rules, an individual investor may be able to offset that net rental loss against other assessable income, such as salary or business income. The immediate tax effect depends on the investor’s marginal tax rate.
That does not mean a loss is automatically a sound investment strategy. A tax deduction reduces the cost of an expense; it does not turn the expense into income. Interest costs, vacancies, maintenance, land tax and cash-flow pressure still need to be funded. A property should be assessed on its likely after-tax cash flow, potential capital growth, risk profile and capacity to withstand changing interest rates.
Conversely, a positively geared property produces net rental income that is generally taxable. Investors should allow for this when setting aside funds for tax, particularly where their rent has increased or interest costs have fallen. The taxable profit is not necessarily the same as cash held after mortgage repayments, because principal repayments are generally not deductible.
Capital gains tax when you sell
When you sell an investment property, capital gains tax, or CGT, is generally considered as part of your income tax return for that year. Your capital gain is broadly the difference between the sale proceeds and the property’s cost base, subject to the detailed rules.
The cost base can include the purchase price, stamp duty, conveyancing costs, certain buyer’s agent costs, capital improvements and some selling costs. Expenses already claimed as deductions cannot generally be counted again. Amounts claimed as capital works deductions may also reduce the cost base, increasing the capital gain on sale.
For individuals and trusts, a CGT discount may reduce an eligible capital gain by 50 per cent where the asset has been held for at least 12 months. Companies are not entitled to the 50 per cent CGT discount. The availability of the discount, and any use of capital losses, should be reviewed before contracts are exchanged rather than after settlement.
The main residence exemption can apply where a property has been your home, but it is not a blanket exemption for every owner-occupied period. Renting out a former home, moving back in, renovating before sale and owning more than one dwelling can all affect the outcome. The six-year absence rule may be relevant in some cases, but it is technical and should be considered against your wider circumstances.
State taxes and ownership structures
Income tax is only one part of the holding cost. Stamp duty is generally a purchase cost rather than an immediate deduction, while land tax is administered by states and territories and can vary by location, ownership type, land value and exemptions. Vacant land, principal residence and trust surcharges may have different treatment depending on the jurisdiction.
The ownership structure chosen before purchase can influence tax, asset protection, borrowing capacity, estate planning and administration. Buying in personal names may offer straightforward access to individual tax rates and the CGT discount. A company may provide a different tax profile but does not receive the individual CGT discount. Trusts can offer flexibility in certain circumstances, but they bring setup costs, compliance obligations and lender considerations. There is no universally best structure, and changing ownership after purchase can trigger duty or CGT consequences.
Keep records that support every claim
Good records protect deductions and make decisions easier. Keep settlement statements, loan documents, invoices, rental statements, agent correspondence, insurance records, rates notices, depreciation schedules and evidence of any private use. Digital copies are practical, provided they remain complete and readable.
Separate records for repairs, improvements and borrowing costs rather than relying on one annual total. If a cost later affects the CGT calculation, a clear invoice and description can be worth far more than a reconstructed estimate years after the purchase.
Tax planning works best before a contract is signed, a refinance is completed or a property changes use. Before your next decision, have the expected cash flow, ownership structure and likely tax treatment reviewed together. That measured approach gives investors a clearer view of what the asset is genuinely delivering, not just what the rent statement suggests.
