Check a Polish company's VAT status in the Ministry of Finance taxpayer register (the 'white list', biała lista KAS) and, optionally, whether a given bank account number is registered to that company. USE THIS before paying an invoice: in Poland, paying over PLN 15,000 to an account outside the white list has tax consequences. Returns VAT status and account-match result. Live query to the official KAS register. Read-only.
