Can You Claim Solar Panel Installation on Your Rental Property?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you can claim solar panel installation on your rental property as a capital works deduction under **Division 43 of ITAA 1997**. The cost is depreciated over 40 years at 2.5% per annum. Always consult a tax professional for tailored advice.

Adding solar panels to your rental property can be a smart move, not only for reducing energy costs but also for potential tax benefits. The installation costs for solar panels on a rental property can be claimed as a capital works deduction under Division 43 of the ITAA 1997. This means that while you can't deduct the entire cost in the year of installation, you can depreciate it over time.

Under Division 43, the cost of installing solar panels is considered capital works, which generally allows you to claim 2.5% of the installation cost each year over a 40-year period. This deduction helps reduce your taxable income, thus lowering your tax liability. It's important to note that the panels must be installed on a property that is used to produce assessable income.

One common misconception is that solar panels can be claimed under Division 40, which covers plant and equipment. However, this is not the case, as solar panels are considered part of the building structure, thus falling under capital works.

Take a practical example: Suppose you own a rental property in Melbourne and decide to install solar panels costing $20,000. Under Division 43, you can claim 2.5% of this amount annually, equating to $500 each year. If you're on a 37% marginal tax rate, this deduction reduces your tax bill by $185 in the first year.

In our experience reviewing thousands of properties across Australia, many investors overlook the long-term benefits of capital works deductions. They often seek immediate returns without considering the steady tax savings over time. Another common pattern is failing to maintain adequate documentation, which can complicate claims. Some investors also miss out by not updating their tax depreciation schedules after making such installations.

The answer can differ depending on your situation. If you installed the solar panels before acquiring the property, you cannot claim the cost. Similarly, if the property is held in an SMSF, different rules may apply. For properties purchased pre-1987, special provisions might affect your ability to claim. Additionally, the rules may vary slightly if the property is commercial rather than residential, or if the panels are installed on a holiday home not primarily used for income generation.

Given these nuances, it's advisable to consult with a Chartered Quantity Surveyor and your accountant. They can ensure that your claims are optimised and compliant with current regulations, providing peace of mind and potentially enhancing your investment returns.

To maximise your tax benefits from solar panel installation:

  • Confirm the installation is on a property generating assessable income.
  • Ensure the cost is recorded under capital works for depreciation.
  • Update your tax depreciation schedule to reflect the new installation.
  • Maintain detailed records and receipts of the installation costs.
  • Consult with a tax professional to tailor advice to your specific circumstances.
  • Review your tax position annually to ensure compliance and optimisation.
  • Frequently Asked Questions

    Can I claim solar panels installed before purchasing the property?

    No, you cannot claim costs for installations made before you acquired the property. Only improvements made during your ownership are eligible.

    How does solar panel installation affect my tax return?

    The installation is claimed as a capital works deduction, reducing your taxable income over 40 years. Ensure your tax depreciation schedule is updated to reflect this change.

    Are there any state-specific incentives for solar panel installations?

    Yes, some states offer rebates or incentives for solar installation. Check with your local government for any available programs that may complement your tax deductions.

    Can I claim solar panels on a holiday home?

    You can only claim if the holiday home is rented out and generates assessable income. Personal use days must be minimal to qualify for deductions.

    Do solar panels qualify for different deductions in commercial properties?

    Yes, while the general principle of capital works applies, specific commercial property rules may influence the deduction rate and eligibility. Consult a QS for tailored advice.
