In my role as a tax agent, I frequently assist business clients in understanding the concept of carried forward losses or business losses. These business losses can significantly impact your tax position in subsequent years, so it’s crucial to understand how they work. Here’s a detailed explanation of what carried forward losses are and how they can be utilised in your business’s tax planning.

1. What is a Carried Forward Loss?

  • Defining the Term: A carried forward loss occurs when a business incurs more expenses than income in a financial year, resulting in a net loss.
  • Carrying Over to Future Years: Rather than being a one-time deduction, this loss can be ‘carried forward’ to offset taxable income in future years.

2. How Carried Forward or Business Losses Work

  • Offsetting Future Profits: If your business makes a profit in subsequent years, the carried forward loss can be used to reduce this taxable income, thereby lowering the tax liability.
  • No Expiry Date: Generally, there is no time limit on how long you can carry forward a business loss in Australia.

3. Conditions for Utilising Carried Forward Losses

  • Continuity of Ownership Test: To apply carried forward losses, most businesses need to pass the continuity of ownership test, demonstrating that the same individuals or entities have controlled the business throughout the loss period.
  • Same Business Test: Alternatively, businesses must pass the same business test, showing that the business has not significantly changed in activities or operations since the loss was incurred.

4. Benefits of Carried Forward Losses and using business losses

  • Tax Planning Tool: Carried forward losses can be a valuable tax planning tool, providing relief in profitable years.
  • Cash Flow Management: They can improve cash flow by reducing the amount of tax payable in profitable years.

5. Reporting and Documentation

  • Accurate Records: Keeping accurate and detailed records is essential for substantiating carried forward losses.
  • Tax Return Declarations: These losses are declared in your business’s tax return, with specific sections for reporting current year losses and losses carried forward.

6. Considerations and Strategy

  • Strategic Use: Consider the best timing for using carried forward losses, especially in years with higher profits or higher tax rates.
  • Long-term Planning: Incorporate carried forward losses into your business’s long-term tax planning strategies.

7. Seeking Professional Advice

  • Complex Regulations: The rules surrounding carried forward losses can be complex, and missteps can lead to compliance issues.
  • Consult a Tax Professional: It’s advisable to work with a tax agent or accountant to navigate these rules and make the most of your carried forward losses.


Understanding and effectively managing carried forward losses are crucial for the financial health of any business. These losses provide an opportunity to offset future taxable income, offering a strategic advantage in managing your tax obligations. With careful planning and professional guidance, you can maximise the benefit of these losses, contributing to the overall success and sustainability of your business.
