Field help: Do you want to claim losses for <%0100301%> from other years in 2025 or claim a loss carryback?

Select "yes" if a loss deduction is to be considered in the tax return 2025 – either as a loss carryback to the previous year (2024) and possibly the year before last, or as a loss carryforward from previous years.

This requires a corresponding loss assessment notice or an application for a loss carryback. The offsetting is automatic.

You can also completely exclude the loss carryback if you prefer to offset the loss in future years.
