Obtain tax authority credentials

Complete these steps to obtain your Polish tax registration before configuring Sovos.

If you don't already have a Numer Identyfikacji Podatkowej (NIP) (10-digit Polish tax identification number), register your business with the Polish tax authority (Urzad Skarbowy). Tax registration with the Polish tax authority gives you a NIP, which is your unique tax identification number that you need for all Krajowy System e-Faktur (KSeF) operations.

Go to the Polish tax authority portal at https://www.podatki.gov.pl/.
Complete the business registration process with your local tax office (Urząd Skarbowy).
Receive your NIP (10-digit tax identification number).
Verify your NIP format is exactly 10 digits with no separators, hyphens, or spaces.
