Submit reports about financial account data according to the Common Reporting Standard (CRS)

Financial institutions must report financial account information to the BZSt insofar as there is a reportable link to foreign countries.

The Common Reporting Standard (CRS) requires financial institutions (e.g. banks or insurance companies) to support the fight against tax evasion. To achieve this, financial institutions must determine in which country their customers are taxable. The Federal Central Tax Office (BZSt) supervises this procedure by, among other things, transmitting the data to the participating states.
More than 90 countries are now involved in the exchange process.
In particular, the following financial account information is exchanged:

  • Name
  • Address
  • State of residence
  • Tax identification number
  • Date of birth
  • Place of birth
  • Account
  • Name and identification number of the financial institution
  • Account balance
  • Interest / Dividends / Other income

Financial institutions must comply with certain due diligence requirements for identifying reportable financial accounts. This includes obtaining self-information. By obtaining self-disclosure, financial institutions want to determine the tax residence of their customers. Account holders must send the self-disclosure to their financial institution in a completed and signed form.
Financial institutions shall report annually in electronic form the accounts identified as reportable to the BZSt. An online form or a mass data interface is available for the transmission of the data. The transmission can also be carried out by a service provider.

Reporting accounts include accounts of:

Accounts of passive entities are accounts that are subject to reporting even if a controlling natural person is established in that country under the tax law of another participating state.

The self-information on tax residence is sent by a financial institution (e.g. banks or insurance companies).

  • Notifiable financial institutions must verify their financial account data in accordance with established criteria for the tax residence of account holders or dominant persons in a reporting State.
  • In particular, when an account is reopened, self-disclosure can be obtained.
  • In the case of existing accounts, the reporting obligation can also be established on the basis of circumstantial evidence. This can be, for example, a current postal or home address, a telephone number, or a currently valid power of attorney in favour of a person with an address in a reporting state.
  • The financial account data determined in accordance with the due diligence requirements must be transmitted annually in electronic form to the Federal Central Tax Office (BZSt).
  • Before the first transmission, a registration of the data transmitter (financial institution or contracted service provider) in the department CRS of the BZSt is necessary.
  • The messages are made via the BZSt-Online Portal (BOP) or the mass data interface (ELMA). This requires a certificate issued by the BZSt (BOP and ELMA) or a certificate issued by the Elster procedure (only possible for BOP). The exact route is described in manuals and videos on the BZSt website.
  • For each transmission, the notifying financial institution or service provider receives technical feedback on the status and result of the processing. Insofar as data has been rejected, the errors must be corrected and the data must be retransmitted.
