Identifying information to sign your tax return

Identifying information to sign your tax return

If you do not have a qualified electronic signature, you can still submit your tax return electronically. You only need 4 pieces of information, 3 of which you could probably provide at any time.

The 4 identifiers to file your annual tax return

  1. Last name
  2. First name
  3. PESEL (or NIP in some cases)
  4. The amount of income shown on your previous year's tax declaration.

Spelling of name

Your surname and first name must always be spelt in the same way as in the population register. 
Alert
If your name contains letters á, é, í, ő, ú, ô, î, č, ţ, etc. with diacritical marks, these must also be entered correctly in the civil registry database, as they appear in your identity document.
In the case of a two-part surname, both must be used.
Any middle name or additional first names do not count as identification data. They do not need to be indicated.

Amount of income declared on your tax return for the previous year

Please look for this on your previous year's declaration!
