If someone asks you for an autónomo registration proof duplicate, they want a fresh PDF that proves two things: that you registered as self-employed with Social Security (RETA, the self-employed Social Security regime) and that you registered with the Tax Agency (AEAT, Spain’s tax agency). The fastest combo is the RETA accreditation from TGSS (the Social Security treasury) and the AEAT census certificate. Both are free and downloadable online with Cl@ve (government login), a digital certificate, DNIe (electronic national ID), or, for TGSS, SMS. This guide shows the exact clicks to get them and what to send in common cases.
Quick Q&A
Is it free? Yes, both proofs are free to download online.
How long does it take? Online is usually instant. If AEAT queues your request, their formal max is 20 working days.
I do not have Cl@ve or a digital certificate. What can I do? Register for Cl@ve online or in person, or use TGSS by SMS if your phone is on file.
Do I also need my 036 or 037 form? Many banks and clients accept the census certificate instead. If they ask for the literal form, you can download your filed 036/037 too (Modelo 036/037 is the business census form you filed to register).
Is vida laboral enough? Vida laboral (your work history report) proves work history, not your tax census. Send it only as a complement, not as a replacement.
Autónomo registration proof duplicate - what counts and where to get it
The two standard PDFs most requesters want are the RETA accreditation and the AEAT census certificate.
They show your self-employed start date, activity, tax status, and ID data. They are accepted by banks, clients, marketplaces, and public programs. Keep both together in one folder.
Fees and timing.
Downloads are free. Issuance is immediate online in almost all cases.
RETA proof from TGSS Importass: download your accreditation
What it is.
The acreditación de alta en trabajo autónomo is TGSS’s official proof that you registered in RETA. It includes your start date and identifiers.
How to download it in Importass.
- Enter Importass (the TGSS online portal).
- Go to "vida laboral e informes".
- Open "acreditación de alta/baja o modificaciones en trabajo autónomo".
- Click "consultar documentos".
Login methods.
Use Cl@ve, digital certificate, DNIe, or SMS if your mobile is registered with TGSS. If SMS fails, add or update your number in Importass first, then retry.
AEAT proof: get your Certificado de situación censal
What it is.
The certificado de situación censal shows your NIF, tax address, IAE activity (IAE is the list of business activity codes), start date, VAT position, and special regimes. Most banks and clients ask for this one.
How to request it online.
- Go to the AEAT site and open "certificados".
- Choose "censales" then "certificado de situación censal".
- Identify with Cl@ve, digital certificate, or DNIe.
- Submit and download the PDF. Issuance is normally instant. If AEAT defers it, their formal max is 20 working days.
Tip: Keep this PDF with your TGSS accreditation. Send both to avoid back-and-forth.
Official reference.
AEAT’s certificate service page explains what the document includes and the valid login methods.
Need the literal 036/037 you filed? download your exact copy
What requesters mean by "copy of 036/037".
They want the exact PDF you filed when you registered, changed data, or deregistered.
How to retrieve it.
- Open the Modelo 036/037 area.
- Go to "consulta de declaraciones presentadas".
- Identify yourself and download the submitted PDF for the date you need.
Practical tip.
Many requesters accept the census certificate instead of the literal form. If the request is strict, send both the census certificate and the 036/037 copy.
Bottom line
To produce an autónomo registration proof duplicate that works everywhere, download two PDFs: the TGSS RETA accreditation from Importass and the AEAT census certificate from the AEAT site. Add the exact 036/037 you filed only when someone insists on the literal form, and include vida laboral as a complement when asked. All of these are free and, in most cases, instant online. Keep them together so you can send the correct autónomo registration proof duplicate any time
