Key Takeaway: The October 31 deadline is the final date for most Australians to lodge individual tax returns without a registered tax agent. Rental property owners can claim deductions for loan interest, repairs and maintenance, property management fees, and depreciation, provided they have proper records and receipts. Gather your documentation now, review all eligible expenses, and lodge on time to avoid penalties and ensure you claim everything you are entitled to.

What Is the October 31 Deadline?

October 31 is the standard deadline for Australian taxpayers who lodge their own individual tax return for the financial year that ended on June 30. If you own a rental property and plan to claim deductions yourself, you must lodge by this date. Missing the deadline can result in penalties and interest charges from the Australian Taxation Office (ATO).

If you use a registered tax agent, your deadline may be extended (often into the following year), but you must have engaged the agent before October 31 to qualify for the extension (ATO, 2026).

What Property Tax Deductions Can You Claim?

Rental property owners can claim a range of deductions related to earning rental income. Common deductions include:

Loan interest: You can claim the interest charged on your home loan for the rental property. Principal repayments are not deductible, only the interest component.

Property management and letting fees: Fees paid to real estate agents for managing your property, advertising for tenants, and lease preparation are deductible.

Repairs and maintenance: Immediate repairs to fix wear and tear (such as fixing a broken tap or repainting a damaged wall) are deductible in the year you incur the expense. However, improvements that add value (such as renovating a kitchen) must be claimed as capital works deductions over many years.

Depreciation: You can claim depreciation on the building (capital works deduction, claimed at 2.5 per cent per year for properties built after 1987) and on depreciating assets such as appliances, carpets, and blinds. A quantity surveyor’s depreciation schedule helps identify these deductions.

Council rates, water charges, and insurance: Ongoing property expenses like council rates, water rates, landlord insurance, and building insurance are deductible.

Strata fees and body corporate charges: If your rental property is in a strata scheme, you can claim these fees.

Other expenses: Pest control, garden maintenance, cleaning, and legal fees related to managing the tenancy or evicting a tenant are also deductible (ATO, 2026).

What You Need to Finalise Your Claim

To lodge your return and claim deductions, you need:

Records and receipts: Keep all invoices, receipts, and bank statements showing expenses paid during the financial year. The ATO requires written evidence for deductions.

Loan statements: Your lender’s annual statement shows how much interest you paid. This is the deductible amount, not the total repayment.

Rental income records: Include all rent received, bond money held (if applicable), and any insurance payouts for lost rent.

Depreciation schedule: If you have not yet obtained a schedule from a qualified quantity surveyor, consider doing so. It can unlock thousands of dollars in deductions over the life of your investment.

Days rented versus vacant: You can only claim deductions for the period the property was rented or genuinely available for rent. If the property was vacant and not advertised, deductions may be limited.

Common Mistakes to Avoid

Claiming the full loan repayment instead of just the interest is a frequent error. Overclaiming repairs (when the expense is actually a capital improvement) or claiming personal expenses are also red flags that may trigger an ATO review. Always keep detailed records and only claim expenses directly related to earning rental income.

When to Get Help

If your rental property finances are complex (multiple properties, co-ownership, significant renovations, or you switched from owner-occupied to investment during the year), consider engaging a registered tax agent. Agents can lodge your return after October 31 under their extended deadline, help maximise legitimate deductions, and reduce the risk of errors.

Conclusion

The October 31 deadline is approaching. Gather your records, review your deductible expenses, and lodge your return on time. Rental property deductions can significantly reduce your taxable income, but only if you claim correctly and keep proper documentation. If in doubt, consult a registered tax agent or visit the ATO website for guidance specific to your situation.
