You can use the loss carry back tax offset tool to work out if you are eligible to claim the refundable tax offset. It also calculates the maximum amount you can choose to claim if you are eligible.
The tool will provide you with a printable report that you can keep for your records. This report will help you complete your company tax return as it displays each label you need to complete to make your claim.
You are an eligible corporate entity if you are both a:
- company, corporate limited partnership or a public trading trust throughout
- the income year that you are claiming the tax offset
- the income year you choose to carry the loss back to (ignoring any part of the year before you existed)
- any income years in between
- small business entity in the loss year or would have been a small business entity if the aggregated turnover threshold was $5 billion.
The rules for calculating aggregated turnover are the same as those used for the small business entity concessions. Your aggregated turnover may include the annual turnover of other business entities, in addition to your own annual turnover.
