I have residence certificates from the consulate, is this also allowed?

Unfortunately, these are not the residence certificates we require. The residence certificates must be requested from the tax authorities in the country where you are fiscally resident. You can request the certificate after January 1, 2025, for all countries from which you receive income.

This is necessary because the residence certificate is not only required for the country of your fiscal residence but also for each other country from which you receive income. This may be important for determining your tax obligations in different countries.
