How to verify the signature on an electronic tax certificate or order

If you receive a tax certificate or order electronically, the document will bear a qualified electronic signature of a tax office employee. As explained by podatki.gov.pl, this signature confirms the authenticity of the document and has the same legal force as a handwritten signature.

Step-by-step verification

If you want to check the signature, follow the steps described in the source:

1. Prepare the signed file — the document you want to check, for example a PDF or XML file.
2. Go to the signature verification page at https://puesc.gov.pl/wer/.
3. Click “Dodaj plik” (“Add file”) and select the document bearing the electronic signature.
4. Click “Weryfikuj podpis” (“Verify signature”).
5. Wait for the result.

To check another document, repeat the same steps.

What information to read from the result

According to the instructions on podatki.gov.pl, the system will show:

• whether the signature is valid,
• who signed the document,
• the date the signature was applied.

Do not treat a valid signature as confirmation that the certificate has favourable contents, that there are no tax arrears, or that a bank or foreign authority will accept the document. Keep signature verification separate from assessing the document’s contents.

Optional organizational note

For your own convenience, you can note down the result, the signatory identified in it and the date the signature was applied. This is an organizational recommendation, not a legal obligation.

This guide describes only the process set out in the source — it does not guarantee a particular result or the availability of the verification service.
