Detailed description
In principle, no receipts or separate statements have to be submitted with the tax return. However, the receipts must be kept for any queries from the tax office.
If, for example, expenses are incurred for the first time, it may be necessary to submit receipts for processing the tax return. In such cases, the tax office will request the receipts.
The obligation to keep receipts applies from the income tax return for the year 2017.
