Permanent Loss Carry-Back for Companies from 1 July 2026
The 2026-27 Federal Budget introduced a significant change for companies that experience a temporary downturn or make investments that result in a tax loss.
The loss carry-back rules have now been permanently reintroduced from the 2026-27 financial year, allowing eligible companies to use current-year tax losses to obtain a refund of tax paid in either of the pervious two income years.
What is loss carry-back?
Normally, when a company makes a tax loss, that loss is carried forward and can potentially be used to reduce taxable income in a future year.
Loss carry-back works in the opposite direction.
Under the new rules, an eligible company that makes a tax loss can choose to carry some or all of that loss back against tax paid in one or both of the previous two income years.
Rather than amending the company’s earlier tax returns, the company receives a refundable tax offset in its current year tax return.
When does it apply?
The new rules apply to income years commencing on or after 1 July 2026.
This means companies with a standard 30 June year-end can first access the new rules when preparing their 2027 company tax return.
Importantly, unlike the temporary loss carry-back rules introduced during COVID-19, the new measure has been introduced on an ongoing basis rather than being limited to particular financial years.
How far can losses be carried back?
A tax loss can be carried back against the company’s income tax liability for either or both of the two immediately preceding income years.
For an income year to qualify, the company must have had an income tax liability in that year.
How much can be refunded?
The loss carry-back benefit is provided as a refundable tax offset.
The refund cannot exceed the tax paid in the previous year and the company’s franking account balance at the end of the loss year.
This means if the company has already paid a franked dividend to shareholders (and therefore has passed on the tax credit), it cannot then receive a refund of the tax paid.
Why is this important for business?
This measure can provide significant cash-flow benefits for businesses whose profitability fluctuates from year to year.
Instead of waiting until the company returns to profitability before receiving any benefit from its tax losses, the loss carry-back provisions can potentially convert those losses into an immediately cash refund of tax previously planned.
Planning opportunities
The reintroduction of permanent loss carry-back makes year-end tax planning increasingly important for companies.
Where a company has paid significant tax during the previous two years but expects its current year taxable income to fall substantially, consideration should be given to whether legitimate expenditure or planned investment should occur before year-end.
The availability of the loss carry-back offset may affect decisions around timing of:
- asset purchases
- repairs and maintenance
- employee bonuses
- deductible business expenditure; and
- other significant investments.
However, the company’s franking account position will also need to be considered, as paying franked dividends can reduce the amount of loss carry-back refund ultimately available.
