Registration for developers
The ELSTER-DTK is made available free of charge to all interested software manufacturers of tax application software, financial or payroll accounting software. For this purpose, registration is initially required. There is no entitlement to the granting of an account. In addition, the tax authorities reserve the right to delete accounts that have already been granted.
You will receive your personal user data (username and password) by e-mail within a few days after registration.
