What Is a NIP Number and Why Do You Need It in Poland?
If you're planning to live or work in Poland, you've probably come across terms like PESEL and NIP. While the PESEL is a personal identification number, the NIP is all about taxes and financial matters. In this blog, we'll break down what a NIP number is, who needs it, how to get it, and why it matters if you're a foreigner in Poland.
What Is a NIP Number?
NIP stands for "Numer Identyfikacji Podatkowej," which translates to Tax Identification Number. It is issued by the Polish tax authorities and is used to identify individuals and entities in all matters related to taxation.
A NIP number is composed of 10 digits and is required for:
-
Filing taxes
-
Running a business
-
Issuing invoices
-
Communicating with tax offices
-
Legal or financial transactions involving Polish institutions
Who Needs a NIP Number?
Not everyone in Poland needs a NIP number. Here's a quick breakdown:
You need a NIP number if you are:
-
A self-employed person (freelancer or business owner)
-
A foreigner working without a PESEL number
-
An employee working for a company that requires it for payroll/tax reasons
-
Registering a company in Poland
-
Required to submit tax declarations independently
You usually do NOT need a NIP if:
-
You are a foreign worker with a valid PESEL number
-
Your employer handles all tax declarations on your behalf
Note: Since 2011, individuals with a PESEL number no longer need a NIP for most personal income tax filings.
Why Is the NIP Number Important?
The NIP number is essential for:
-
Paying personal income tax (if self-employed or required by contract)
-
Registering as a VAT taxpayer
-
Operating a business legally in Poland
-
Receiving payments from Polish companies
-
Signing financial documents
-
Keeping your tax records clear and trackable
Without a NIP (or PESEL), it's almost impossible to carry out official financial activities.
How to Apply for a NIP Number in Poland
To apply for a NIP number, follow these steps:
-
Fill out the NIP-7 form – This is the standard application for individuals not conducting business.
-
Provide necessary documents:
-
Passport or national ID
-
Visa or residence permit
-
Proof of address in Poland
-
Work contract or employment confirmation (if applicable)
-
-
Submit your application to the local tax office (Urząd Skarbowy) in person or via post.
Processing time is typically 1–2 weeks, and the NIP number will be sent to your registered address.
