What Are the Penalties for Incorrect Depreciation Claims?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Incorrect depreciation claims can result in penalties imposed by the ATO, including fines and interest charges. Under Division 40 and Division 43 of the ITAA 1997, it's crucial to ensure claims are accurate. Incorrect claims may lead to adjustments and penalties based on the tax shortfall. Engage a Chartered QS to avoid these issues.

Incorrect depreciation claims on investment properties can lead to significant penalties from the Australian Taxation Office (ATO). These penalties can include fines, interest charges, and adjustments to your tax return. Under Division 40 and Division 43 of the ITAA 1997, it's crucial for accountants to ensure their client's depreciation claims are accurate and compliant with current legislation.

One common misconception is that investors can freely claim depreciation on any asset without considering its effective life or eligibility. However, the ATO requires precise calculations, and incorrect claims can lead to tax shortfalls. If the ATO discovers discrepancies, they may issue a penalty based on the severity of the error, often calculated as a percentage of the tax shortfall. This can range from 25% to 75% of the shortfall, depending on whether the error was due to lack of reasonable care, recklessness, or intentional disregard of the law.

To see how this plays out, consider a scenario where an investor incorrectly claims $10,000 in depreciation for a second-hand plant and equipment asset purchased after 9 May 2017. If the ATO determines that this claim was made recklessly, a penalty of 50% of the tax shortfall could be applied. Assuming a tax rate of 37%, this results in a tax shortfall of $3,700, leading to a penalty of $1,850 plus interest charges.

In our experience reviewing thousands of properties across Australia, we've found that investors often misunderstand the rules surrounding second-hand properties and the effective lives of assets. Many assume that all assets can be depreciated without understanding the nuances of the 2017 budget changes. Additionally, we've seen cases where investors fail to update their depreciation schedules after significant renovations, missing out on potential deductions and exposing themselves to compliance risks.

The answer can differ depending on your situation. For instance, if the property was acquired before 7:30pm AEST on 9 May 2017, the rules regarding second-hand plant and equipment do not apply. Similarly, if the property is commercial rather than residential, different depreciation rates and rules may be applicable. Owners of properties held in a Self-Managed Super Fund (SMSF) also face unique considerations, especially regarding compliance and audit requirements.

Given the complex nature of tax legislation, it's advisable to consult with a Chartered Quantity Surveyor and an accountant to ensure your client's depreciation claims are accurate. A QS can provide a detailed depreciation schedule, while an accountant can ensure these claims are correctly reported on the tax return.
