Checking VAT Numbers within SAP®

As of January 1st, 2010, companies are required by law to check the VAT number of any business partner within the European Union. Neglecting this requirement might lead to drastic consequences in regard to your taxes.

A confirmation process via the Federal General Tax Office allows you to check foreign VAT-numbers. The Office informs you about the current validity of VAT-numbers of affected member states and if company name, place, ZIP code and street name are equal to those found in the EU registry of member states – including the legal form of companies contained in the trade register.
