Can I Claim Depreciation on Garages and Carports?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you can claim depreciation on garages and carports as part of your investment property in Australia. These structures typically fall under **Division 43 of ITAA 1997**, covering capital works, and can be depreciated at a rate of 2.5% per year over 40 years. Ensure accurate cost assessments to optimise your tax deductions.

Depreciating garages and carports can be a valuable tax deduction for property investors in Australia. Under Division 43 of ITAA 1997, these structures are considered capital works, meaning you can claim a 2.5% deduction annually over 40 years. This depreciation applies to the structural components of garages and carports, provided they are part of a rental property or used to generate income.

A common misconception is that garages and carports automatically qualify for depreciation without proper documentation. In reality, you need detailed cost assessments and records of construction dates and expenses. This ensures compliance with ATO requirements and maximises your deductions.

Take a practical example: Imagine you own a 2010-built 3-bedroom house in Melbourne with a detached garage and carport. The construction cost of these structures was $40,000. Under Division 43, you can claim a 2.5% annual depreciation, equating to $1,000 per year. If your marginal tax rate is 37%, this results in a tax saving of $370 annually.

In our experience reviewing thousands of properties across Australia, investors often overlook garages and carports when calculating depreciation. Many assume these structures are minor and don't realise the cumulative tax benefits. Additionally, failing to update depreciation schedules after renovations or improvements can lead to missed deductions.

The answer can differ depending on your situation. If your property was built before 1987, garages and carports may not qualify under Division 43 unless subsequent renovations occurred. Properties acquired after 9 May 2017 also face restrictions on claiming Division 40 for second-hand plant and equipment within these structures. Commercial properties may have different rules, so it's essential to assess each case individually.

Given the complexities, working with a Chartered Quantity Surveyor and accountant ensures you capture all eligible deductions. They can provide precise construction cost assessments and tailor advice to your specific property and financial situation, helping you achieve optimal tax outcomes.

  • Gather construction cost details for your garages and carports.
  • Consult a Chartered Quantity Surveyor for a detailed depreciation schedule.
  • Review your property's construction and renovation history for additional deductions.
  • Discuss your depreciation strategy with an accountant.
  • Update your tax return with the latest depreciation figures.
  • Regularly review and adjust your depreciation schedule for any property changes.
