Field help: (2020) Loss carryforward from capital assets with final withholding tax (sect. 20 para. 6 sentence 5 of the Income Tax Act (EStG))

If your negative income is not offset or not fully offset in the previous year, you will receive an assessment notice on the "remaining loss carryforward".

Losses that have not been offset are carried back for one year and offset against the positive profits of the previous year. If a loss continues to exist after the carryback, the loss will be carried forward by your tax office to the next year. You can limit the amount of the loss carryback if you expect little or no tax effect from the loss deduction in the previous year.

As a rule, losses from taxable sales transactions can only be offset against profits from other taxable sales transactions.
