Can You Claim Home Office Expenses for Managing Properties?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Yes, you can claim home office expenses if you manage your own properties, but conditions apply. The ATO requires that the home office be used exclusively or primarily for property management tasks. Ensure you only claim legitimate expenses like electricity, internet, and a portion of your home office furniture depreciation.

Claiming a home office expense is a common consideration for property investors who actively manage their rental properties. Under the ATO's guidelines, you can claim home office expenses if your home office is used to manage your investment properties. However, the claims must be reasonable, justifiable, and in line with ATO standards.

The key to claiming home office expenses is the purpose and extent of use. The ATO allows you to claim a portion of your home expenses if you use a specific area of your home exclusively or primarily for managing your properties. This might include tasks like arranging repairs, managing finances, and communicating with tenants. Importantly, the space must be a dedicated area, such as a study or office, not just a corner of your living room.

Common misconceptions include believing that any area of the home qualifies or that you can claim the entire cost of household expenses. The reality is, only the proportionate expenses related to your home office can be claimed. These include a portion of electricity, internet, phone expenses, and even depreciation on office furniture.

To see how this plays out, consider a practical example. Suppose you have a three-bedroom house in Melbourne, and you use one room solely as an office to manage your two investment properties. The room accounts for 10% of your home's floor space. Your annual home expenses are $20,000 for electricity, internet, and other utilities. You could claim $2,000 (10% of total expenses) as a deduction. If your marginal tax rate is 32.5%, this equates to a tax saving of $650.

In our experience reviewing thousands of properties across Australia, investors often neglect to maintain adequate records. Keeping detailed logs of your home office usage and related expenses is crucial. Another common oversight is failing to adjust claims proportionally to actual use, leading to potential issues with the ATO.

The answer can differ depending on your situation. If your home office is used for multiple purposes, you can only claim the proportion of time it is used for property management. Additionally, if you started using your home office mid-year, you must prorate the expenses accordingly. For properties owned jointly, each owner can only claim their share of expenses. Lastly, if your properties are held through a trust or company, the rules differ significantly, and professional advice is recommended.

Given the complexity and the potential for ATO scrutiny, professional advice is invaluable. A Chartered Quantity Surveyor can help ensure your claims are accurate and optimise your deductions. Coupled with an accountant, you can navigate the nuances of tax law effectively.

  • Frequently Asked Questions

    Can I claim home office expenses for a shared office space?

    You can only claim the proportion of expenses that relate to the time you use the space for managing your properties. Shared use requires careful calculation.

    How does claiming a home office affect CGT?

    Claiming a home office may impact the CGT exemption on your primary residence. It effectively partially removes the exemption for the portion of the home used as an office.

    Are there state-specific rules for claiming home office expenses?

    While the basic principles are consistent nationally, state taxes and additional levies might apply. Check with your local state revenue office for specific details.

    What records do I need to keep for my home office claim?

    Keep records of all expenses, a floor plan of your home showing the office, and a log of the time spent on property management tasks.

    Do I need to include home office expenses in my tax return?

    Yes, you need to report these expenses in your tax return. They should be included in the section for rental property expenses.
