KSeF is a state system for the exchange of electronic invoices. The ZAW-FA form is submitted to assign, change, or revoke permissions for working within KSeF. Below are brief instructions on how to fill it out correctly.

ZAW-FA — Instructions on Granting Rights to Use KSeF for Companies

1
To fill out the electronic version, you must download the form using this link and open the downloaded file in a browser window.
If it is not possible to fill out the form electronically, you can download, print, and fill it out manually following the sample.

In Field 1 of the ZAW-FA form, you must enter the NIP of the submitting entity (company).

In Section A (points 5-6), specify the appropriate Tax Office (Urząd Skarbowy) and the purpose of submitting the form.

2
In Section B.1, you must enter the taxpayer's identification data (company).

In Section B.2, you must enter the taxpayer's contact details. In Field 10, it is mandatory to provide an e-mail address, as information regarding the granting or revocation of KSeF usage rights will be sent to it.

3
In Section C.1, you must enter the identification data of the authorized board member to use KSeF.
Fields 16-18 should only be filled out if the individual does not have a PESEL number.

In Section C.2, provide the phone number and e-mail address of the person authorized to use KSeF.

Field 20, regarding the e-mail address, is mandatory, as the authorized person will receive a notification of the KSeF usage rights being granted to this address.

4
In Section E, enter the first name, last name, and position (e.g., PREZES ZARZĄDU / CZŁONEK ZARZĄDU) of the persons authorized to represent the taxpayer submitting this form.

If the company's Articles of Association require joint signatures from several individuals, all such individuals must sign in Section E. If each authorized representative has the right to act independently, the signature of one authorized person is sufficient. When there are more than six signatories, additional ZAW-FA forms should be used.

Congratulations, all the data in the form has been filled out!


Now, all that remains is to sign the form with a Profil Zaufany and send it using e-Doręczenia. The form must be sent not from the company's account, but from the personal account of the individual for whom this notification is being submitted. You can find the e-Doręczenia address for your Tax Office in the search engine.

In the case of manual filling, the form can also be scanned and signed with a Profil Zaufany. If the form is both filled and signed physically, it must be sent by mail or submitted in person at the Tax Office (Urząd Skarbowy).

In e-Doręczenia, when filling out the fields in the message, you must specify:
Temat wiadomości – ZAW-FA
Treść wiadomości – Zawiadomienie o nadaniu uprawnień do korzystania z Krajowego Systemu E-Faktur
After filling in all the fields and adding the completed ZAW-FA form as an attachment, select Wyślij and send the message.

The sent message will appear in the Moja skrzynka → Wysłane section.

Once you receive the confirmation of registration in KSeF via e-mail, you can proceed to managing permissions for processing invoices and synchronizing KSeF with Saldeo.
