Hello,
I have some questions about the required compliance documents, specifically the proof of tax identification number (NIP number). Do I need to submit this document to start working if I'm not obligated to pay taxes in my country (Poland) yet because I'm only 23 years old (it's not obligatory until 26 years old)? Also, if it is necessary, what kind of document should I submit? In our country, individual employees don't have NIP numbers (it's only for business activities), but we have a PESEL number that can be found, for example, on identity cards.
Thank you in advance for the answer
