Every company in Poland has a VAT number (NIP), but this does not mean that it is registered as a VAT payer. Transactions with companies that are not registered as VAT payers may have many negative consequences for you, so we suggest you always check whether your customer or supplier is a VAT payer. Consider also, that company which is registered as VAT payer today, could be removed from the list of VAT payers in the future.
