From 1 June 2021, foreigners who do not have a PESEL number can apply for it for tax filing purposes at their local gmina office. Thanks to the new regulations, more foreign nationals will be able to access the “Twój e-PIT” service (learn more about it here: Your e-PIT) and fill in their tax return via the e-Deklaracje application, meaning they will also be able to claim tax reliefs, deductions and tax refunds. However, it is worth noting that from now on, documents with wrong identification numbers (including strings of numbers such as 1111111111) will no longer be accepted by the Tax Office. Those taxpayers who used NIP instead of PESEL as their identification number are required to obtain a PESEL number within 30 days.

Note that foreigners who register their residence address in Poland (temporary or permanent) are automatically granted a PESEL number. Learn more about Registered residence address in Poland.
