In the past a correct VAT-ID-No was only a conventional prerequisite for intracommunity supplies. In practice businesses often checked and verified the VAT-Id.No. only once when the client data base is recorded for the for the first time. Due to the changes as of January 2020 the tax exemption of intracommunity supplies is in that cases highly at risk. If a wrong VAT-ID-No is detected only after years high VAT payments and penalties may occur. A regular check of VAT-ID-No of business partner is therefore of utmost importance. 

Our solution: our Value Added Tax Identification Number Information System (V.I.S.) To avoid that minor mistakes become extremely expensive, V.I.S. verifies VAT-ID-No. and helps to correct invalid address data. Furthermore, V.I.S. supports based on the data base of the German Federal Office for Tax (BZSt) and the European MIAS   to keep your customer base data actual regarding your VAT-ID.No. and correspondingly helps with a frictionless tax planning and handling. With the new repository function the received data files of the BZSt can be stored and kept as proof for the tax exemption of your intracommunity supplies.

Questions and answers

Which companies are particularly affected?
  • All companies with deliveries within the EU and from 2010, that render cross-border (EU) services
  • Companies with an extensive customer base
  • Companies with a constantly changing customer base

Each entrepreneur is required to verify the correctness of the VAT ID number in compliance with due diligence of a prudent business person. Especially due to the mounting corporate insolvencies, there is a risk of a 19 percent margin loss. In practice, the VAT ID number and the corresponding address data are currently usually entered individually and manually on the website of the Federal Central Tax Office (BZSt). Therfore, address errors oftentimes lead to insufficient query results. Manual amandments of the costumer base lead to an excessive work effort. Tax departments are frequently not able to assess the latent VAT risk.
