What should I do if the verification of my data has failed?

If you receive the message "... Error!", there are one or more errors in your data. In this case, Lohnsteuer kompakt will provide you with information about which data caused issues.

Simply click on the relevant link and enter any missing data or correct the incorrect entries. In some cases, multiple entries you have made will be checked for plausibility. In this case, the input fields may be on different pages. Usually, the error description will indicate where the fields to be checked are located.

Then check the data again. Once all errors have been corrected, you can submit your tax return to the tax office via ELSTER.
