Request a Convenio Especial with the Seguridad Social

What you need to have to hand

1. Cl@ve, certificado digital o DNIe. Without one of these you can't do it online.
2. Vida laboral and, if possible, informe de bases. They help you pick a base and avoid getting it rejected.
3. Proof of cessation (dismissal letter, end of contract, baja en RETA, ERE…). If it's a special case, bring the resolution that proves it.
4. IBAN to set up the direct debit. They charge you monthly.
5. A clear idea of the base you want and the effective date.

Documentation

• DNI/NIE valid.
• Vida laboral and informe de bases (from Import@ss).
• Document proving cessation or the applicable resolution (ERE, relocation, return…).
• IBAN for the direct debit.
• If you go to an office: Modelo TA.0040 Solicitud de Convenio Especial.

Step by step

1. Go to importass.seg-social.es and identify yourself with Cl@ve/certificado/DNIe.
2. In the search box, type “Convenio especial” and choose the service. Select the type that fits your situation.
3. Fill in: contribution base (watch limits according to your previous bases), effective date and bank account.
4. Attach the supporting documents: vida laboral/bases and the cessation document or the resolution that applies.
5. Review the calculation of the fee the system shows. If it looks right, sign and download the receipt.
6. Keep an eye on Import@ss and the DEHú for any request to correct documentation. Fix it within the deadline or the process will fail.
7. When the resolution arrives, check base and date. From then, the monthly direct debit applies. Keep the receipts.

Tips that save time

• Get the vida laboral and bases before you start; it avoids guesswork about the base.
• If you're unsure what type applies, read the info sheet in Import@ss first and prepare the resolution from SEPE/INSS/company that proves it.
• If the system won't let you pick that base, don't keep forcing it: it's because of TGSS limits. Pick the next allowed option and request a change later in the window.
• Turn on notifications in the DEHú so you don't miss a request to correct documents.

Common mistakes that can derail the process

• Applying late expecting retroactive effect. It usually isn't. You lose months of contributions.
• Not paying three months in a row: termination and you may have to start over (if they let you).
• Choosing a base that doesn't apply because of your previous bases or age: they'll stop it or request changes.
• Uploading blurry or incomplete documents: you'll get a request and delays.
• Going to an office without an appointment or without the TA.0040: wasted trip.
