How to benefit from the reverse charge procedure

Checking the VAT ID with Uniserv

More and more companies are outsourcing their logistics to other European countries and supplying their German customers from there. When the supplier and the recipient are in different countries, but are liable to pay VAT within the European Union, then the so-called reverse charge procedure can be applied. This procedure simplifies the treatment of VAT by transferring the reporting obligation from the supplier to the recipient. However, the prerequisite for VAT-exempt supplies under the reverse charge procedure is that the recipient is actually a VAT-liable company and the supplied item was purchased for the company. The supplier must perform the due diligence and show that the facts were checked properly.

In order to benefit from the VAT-exempt supply under the reverse charge procedure, you must therefore prove that the recipient is actually a VAT-registered company. The prerequisites for this are the correct company address and the valid VAT ID. The Uniserv Company Check supports you in securing & checking this data:


Verification and, if necessary, correction of the company name as well as the registered office, enrichment of the entry in the commercial register and plausibility check of the VAT ID for German companies.

Enrichment of missing data: Company name and entry in the commercial register.

Access to various types of registers, such as commercial register A or B, partnership register, association register or cooperative register.
