Frequently asked questions
Can foreign companies registered for VAT in Germany use ELSTER?
Yes. Non-resident companies with a German VAT registration are required to use ELSTER to submit their VAT returns. They must register on the platform and can authorize a local tax representative to file on their behalf.
Do I need to register a new ELSTER account if I change my company’s legal structure?
Yes. If your business changes its legal structure (e.g. from sole proprietorship to GmbH), you must register a new ELSTER account for the new entity. The tax number changes, and each legal entity must have its own ELSTER certificate.
What types of VAT returns are filed through ELSTER?
Through ELSTER, businesses are required to submit several VAT-related filings, including the advance VAT return (Umsatzsteuervoranmeldung), the annual VAT return (Umsatzsteuerjahreserklärung), and the recapitulative statement for intra-EU supplies (Zusammenfassende Meldung), all of which must be submitted electronically.
How long does it take to receive an ELSTER certificate after registration?
The registration process for an ELSTER certificate can take approximately one week. After initiating the process online, an activation code is sent by mail, which may take several days to arrive.
Can I integrate ELSTER with my ERP or accounting software?
Yes, many ERP and accounting software solutions offer integration with ELSTER. For example, SAP provides an ELSTER integration add-on that enables automated transmission of VAT returns directly from the SAP system to the tax authorities. This integration can be done following SAP Standard or with a custom solution. Contact us to evaluate your needs.
What are the penalties for late VAT return submissions via ELSTER?
Late submissions may incur penalties of up to 10% of the assessed VAT amount, capped at €25,000. Additionally, late payments can attract interest charges of 1% per month of the outstanding VAT.
How mandatory ELSTER reporting will impact business in Germany
The integration with the ELSTER (Electronic Tax Declaration) system in Germany represents a fundamental requirement for all VAT-registered companies operating in the country. Businesses are required to submit recurring tax returns, including VAT advance notifications and annual tax statements, through this centralized electronic interface using specific security certificates. This means that ERP systems must be capable of extracting, validating, and transmitting precise financial data in the mandated XML format, ensuring that all communications with the Finanzamt are conducted in a fully automated and secure way.
At Code10, we support this transition through a combination of SAP Standard implementation and advance eCompliance integration delivered via our eCompliance Hub. We maximize SAP’s native functionalities wherever applicable and develop targeted enhancements when regulatory or technical requirements go beyond standards capabilities. Our approach ensures structured data extraction, certificate-based authentication, and secure transmission to the German fiscal portal, enabling organizations to meet German ELSTER obligations efficiently and with full technical reliability.
