Data boxes being made available to business persons by law also means that a person who has access to this data box must make form submissions electronically, with regard to submissions that relate to an activity that he or she is at least partially involved in as a business person. For example, this applies to filing a personal income tax return for income relating to his or her business activities. Electronic filing can be done via the data box as well as via the “MOJE daně” portal.
If a natural person has a data box set up as both a non-business and a business person, it is entirely up to him or her to choose which data box to use.
The deadline for electronic filing of personal income tax returns for 2022 tax year is May 2, 2023, unless they are filed by a representative.
