Ladies and Gentlemen, due to numerous telephone calls, we would like to inform you that since yesterday, i.e. November 29, 2022 (Tuesday), there is a system failure on the part of the Ministry of Finance. The problem was reported to the Ministry of Finance's e-mail contact box yesterday. Unfortunately, there is nothing we can do except be patient. As soon as the List of VAT Payers starts returning correct answers, our API will also send them correctly to your systems.
The problem was officially confirmed today on the Ministry of Finance websites: https://www.podatki.gov.pl/komunikaty-techniczne/problemy-techniczne-z-wykazem-podatnikow-vat-301122/
