Where can I find my registration documents in self-service?

Last updated: February 24, 2026

If you need to download your self-employment registration documents, you can do so directly from your platform. Access your profile, click on your name in the bottom left corner, and go to business settings.

Once inside, click on "Documents" and there you will find your DUE (Documento Único Electrónico), which is the document used to register you with both the Tax Agency and Social Security.

If you require Form 036, you can request it by sending an email to ayuda@xolo.io and our team will upload it to the same "Documents" section.

If you need your Social Security proof of registration, you can download it directly from the Social Security website. In this FAQ, we explain step by step how to do so.

You will also find other documents related to your activity, such as form 036 for changes of address or other models submitted.
