General Information

You have various options to submit your applications and reports electronically via the Internet to the Federal Central Tax Office (BZSt). Electronic data communication requires a registration at the BOP for the authenticated transmission of the forms or for mass data (ELMA5).

Please note that in addition to the registration at the BOP, an application for the activation of the ELMA5 procedure of the BZSt is required for the authenticated transmission of your mass data.

My BOP

The online portal of the BZSt enables you to file your national tax data (e.g. church tax on capital gains, control procedure applications for exemption, insurance and fire protection tax, etc.) and international tax data (e.g. mini one-stop shop, input tax refund, recapitulative statement, etc.) completely paperless. All you need for this is a BZSt number to start the registration in BOP.
The use of the BOP is only possible after registration with an electronic certificate: To the registration
