If income remains negative after the loss offset in the same year, you can choose to offset this amount either in the previous year or in subsequent years (loss deduction according to § 10d EStG).
Many self-employed individuals and business owners suffered losses in 2020 and 2021 due to the coronavirus crisis. The tax loss carryback was originally limited to 1.000.000 Euro for single individuals and 2.000.000 Euro for married couples.
In 2020 and 2021, the loss carryback was increased to 5.000.000 Euro or 10.000.000 Euro for joint assessment.
The "Third Coronavirus Tax Assistance Act" of 17 March 2021 increased the loss carryback to 10.000.000 Euro or 20.000.000 Euro for the years 2020 and 2021, also for the provisional loss carryback for 2020.
From 1 January 2022, the loss carryback was permanently extended from 1 year to 2 years. The increased loss deduction of 10.000.000 Euro or 20.000.000 Euro for the years 2022 and 2023 remains in place.
This means that the limits will only be reverted to the previous level of 1.000.000 Euro or 2.000.000 Euro for jointly assessed spouses from 2024.
Note: The option for loss carryback has been restricted. From 2022, you can only opt out entirely, not carry back a partial amount. "At the request of the taxpayer, the loss carryback is to be waived in full" (§ 10d para. 1 sentence 6 EStG-new). This means that the option to limit the amount of the loss carryback on request is no longer available.
If negative income cannot be offset by loss adjustment in the year the loss occurs and by loss carryback to the previous year, please always tick the box "Declaration for the determination of the remaining loss carryforward" at the top of page 1 of the main tax form.
