Do you want to claim losses for <%0100301%> from other years in 2020 or claim a loss carryback?
Select Yes if you want to claim a loss deduction or a donation carryforward.
Loss carryback in the previous year: Negative income that is not balanced out in the year in which the loss occurs can be carried back in the previous year. Since 2013, an amount of up to 1 million Euro - up to 2 million Euro for married couples - can be carried back in the previous year.
Loss carryforward/donation carryforward to the following year: If the negative income is not or not completely offset in the previous year, you will receive an assessment notice on the "remaining loss carryforward". This amount is then deducted from the total amount of income in the income tax assessment for the following year up to a total amount of 1 million Euro - for married persons 2 million Euro. If the loss amount is even higher, the excess amount is offset up to 60% of the total income amount in the following year, so that 40% of the profit is always taxable.
Note: For the years 2020 and 2021, the tax loss carryback will be increased to a maximum of 5 million Euro or 10 million Euro in the case of joint assessment (sect. 10d para. 1 sentence 1 Income Tax Act (EStG), amended by the "Second Corona Tax Assistance Act" dated 29.06.2020).
