Upload your autónomo registration
You can attach the PDF of the registration. If the file is not recognized, it is not thrown away: it stays saved and you complete the data. The app does not register you with the Tax Agency.
Which files you can upload
The registration (the DUE), the deed, the CIF card, or modelo 036 or 037. These are documents you already have. The app does not request them from the Tax Agency for you.
- Registration or DUE, as a PDF.
- Deed.
- CIF card.
- Modelo 036 or 037.
If the file is not recognized
It is saved anyway. You complete the name, the tax ID, and the rest on the record. Uploading the PDF is not the census registration: that step is done with the Tax Agency, outside the app.
Common questions
Does Factura Fácil register me as an autónomo?
No. It stores the document you were already issued. Registration with the Tax Agency is not done from the app.
What if the PDF cannot be read?
The file is kept and you complete the data yourself. Recognition does not have to succeed for the document to be saved.
