Notification about Change of Tax Number
Dear Partner,
We would like to inform you that Semmelweis University (registered office: 1085 Budapest, Üllői út. 26., institutional ID number: FI 62576) and some of its affiliated companies are scheduled to form a VAT group as of January 1, 2025. Under VAT regulations, on the invoices issued after January 1, 2025 to companies that are part of the VAT group, and for transactions with a completion date after January 1, 2025 both the VAT group tax number and the customer’s individual tax number must be indicated. Please note that upon the establishment of the VAT group, the 9th character of the individual tax numbers of participating companies will change to “4.”
If the invoice does not include both tax numbers or if the tax numbers are indicated incorrectly, we will not be able to accept the invoice.
Other than the tax number, there are no changes to any other details or contact information of Semmelweis University or the other companies belonging to the group. Invoice acceptance shall continue as before, with the only difference being the data required to be present on the invoices as stated above.
