When a property serves both personal and business purposes, the ATO requires a clear distinction between these uses for tax deduction purposes. Under Division 40 of the ITAA 1997, you can claim depreciation on plant and equipment that is used for business, while Division 43 covers capital works deductions. The key is to apportion expenses based on the actual business use of the property.
A common misconception is that you can claim the entire property's expenses if it is occasionally used for business. However, the ATO mandates that only the portion of the property used exclusively for business qualifies for deductions. This requires precise calculation and documentation to avoid penalties.
To see how this plays out, consider a scenario where you own a property valued at $800,000 in Melbourne, with a dedicated office space constituting 20% of the total area. If your total property expenses, including mortgage interest, utilities, and maintenance, amount to $30,000 annually, only $6,000 (20% of $30,000) can be claimed as a business expense. Additionally, depreciation on the office equipment and capital works can be claimed proportionally.
In our experience reviewing thousands of properties across Australia, many business owners overlook the need for precise apportionment. They often either overestimate the business use or fail to maintain adequate records, both of which can lead to ATO audits and penalties. It's crucial to have a clear, documented basis for your claims, such as floor plans, usage logs, and photographs.
The answer can differ depending on your situation. If you purchased the property after 9 May 2017, you cannot claim depreciation on previously used plant and equipment for residential properties, though this does not apply to commercial properties. Joint ownership requires each party to claim according to their interest in the property, and special rules apply if the property is owned by an SMSF.
Tax implications depend on individual circumstances, and a Chartered Quantity Surveyor, in conjunction with your accountant, can ensure that you maximise your deductions legally. This collaboration is particularly important for mixed-use properties due to the complexity of apportionment and depreciation rules.
