When do we use the PESEL number and when do we use the NIP number?

Pursuant to the Act on the principles of registration and identification of taxpayers and payers, the PESEL number is the identifier of persons which: 

  • are included in the PESEL register,
  • do not run a business,
  • are not registered VAT payers,
  • are not tax payers,
  • are not payers of social security and health insurance contributions.

In contacts with the tax office, the NIP number is used by taxpayers which:

  • are persons conducting business activity subject to entry in the CEIDG,
  • are persons who are not entrepreneurs (they are not subject to entry in CEIDG), but conduct business,
  • are persons who are not entrepreneurs (they are not subject to entry in the CEIDG), but are registered as a VAT payer or are subject to registration as a VAT payer,
  • do not run a business that is not covered by the PESEL register,
  • do not run a business as a tax payer,
  • do not run a business as a payer of social security and health insurance contributions.

Simply put – those  who work under a mandate contract or a contract of employment should apply for a PESEL number, which is a very important identifier in our country and serves to facilitate  identification not only for tax purposes. People who run a business in any form – will not open it without providing a tax identification number.  How to apply for a PESEL number, where to do it is explained in the next entry.
