Tax Losses can either be carried forward or carry back losses.
Carried Back Tax Losses
These are laws that provide a company with the choice to carry back all or part of a tax loss from an income year, or the previous income year, against their income tax liability in either of the two previous income years. The losses are capped at $1,000,000. Therefore up to $300,000 in cash will potentially be available to some companies.
Carried Forward Tax Losses
Companies can generally carry forward a tax loss indefinitely. The loss can be deducted in their year of choosing provided that since the loss was initially incurred the company has:
1. Satisfied the continuity of ownership test (COT) and the control, test; or
2. Satisfied the same business test (SBT).
