The pre-filled tax return is a service provided by the German tax authorities. Certain data which is provided by third parties (health insurance companies, employers etc.) to tax authorities can be automatically entered into a citizen's tax return if the citizen gives the necessary authorization.
OOP aspect
The German tax authorities re-use the data provided to them from other relevant parties (insurance companies, employers etc.). Therefore taxpayers do not have to re-enter data but can simply check the data provided through the pre-filled tax return.
Short summary
The pre-filled tax return is a service provided by the German tax authorities. If citizens choose to file their tax returns digitally, they have the option to use the pre-filled tax return. Certain data which is provided by third parties (health insurance companies, employers etc.) to tax authorities can be automatically entered into a citizen's tax return if the citizen gives the necessary authorization. Citizens can then complete the tax return and submit it digitally.
Currently, the following data can be automatically retrieved by citizens:
- personal information (name, religious affiliation, address, bank information)
- information from the employment tax statement
- information on wage replacement benefits (e.g. unemployment assistance and social welfare)
- information on retirement benefits
- information on basic health insurance and statutory nursing care insurance dues
- information on pension plan dues

Insurance companies and employers have to submit the data to the tax authorities by February 28th of the respective year in order for the data to be used in the tax return.
Therefore, citizens do not have to manually re-enter the same data; tax authorities re-use data other agencies have already shared with them. This service provides several benefits to citizens:
- less mistakes due to no manual data entry
- saves time
- more transparency (citizens can see and check what data tax authorities receive from insurance companies and employers)
- reduces the administrative burden for citizens overall
