Request additional supplements to your pension (Gestión 16, INSS)

What you need to have ready

1. Cl@ve, certificado digital or DNIe that works. If Cl@ve won’t sign, use Cl@ve Firma.
2. Pension file number from the INSS (it appears on the recognition letter or in your notifications).
3. Scanned documents in PDF: DNI, libro de familia/certificates of children if you’re applying for brecha de género, padrón colectivo if you claim cónyuge a cargo, IRPF and income certificates, and your IBAN.
4. A browser that doesn’t mess you about. The Sede works better in Chrome/Edge. Attachments have size limits; compress PDFs if needed.

Documentation

• Identity: DNI/NIE of the pensioner (and of the spouse if you claim mínimos with cónyuge a cargo).
• Family link: libro de familia or birth/adoption certificates (brecha de género).
• Cohabitation: padrón colectivo recent if you claim cónyuge a cargo.
• Incomes: last declaración de la renta and current certificates (bank, rents, payslips, foreign pensions, etc.).
• Foreign pensions: annual certificate with amount and currency.
• Bank account: document with IBAN in your name.

Step by step

1. Gather and name your PDFs: make each file obvious. Avoid blurry photos.
2. Go to the Sede del INSS: https://sede.seg-social.gob.es with Cl@ve/certificate. If it’s for brecha de género, look under Ciudadanos > Pensiones and use that service.
3. If you don’t see the clear button (or it’s complemento a mínimos), use the Registro Electrónico Común (REC): https://rec.redsara.es. Organism: Instituto Nacional de la Seguridad Social (INSS), destination: Dirección Provincial of your province.
4. In the subject put "Solicitud de complemento a la pensión (mínimos / brecha de género)". In the body give your DNI, pension file number, type of pension and since when you receive it. List the attachments.
5. Attach all PDFs. If there are many, upload them as separate annexes. Better one PDF per document.
6. Sign and register with Cl@ve Firma or certificate. Save the receipt (PDF with asiento number) like it’s important.
7. Check DEHú: https://dehu.redsara.es and your email. If they ask for a subsanación, reply through the same expediente in the REC uploading what’s missing.
8. When the resolution arrives, check the cuantía and the date of effects. If it doesn’t add up, file a recurso within 30 working days via the REC, arguing with law and evidence.

Time-saving tricks

• If you apply for mínimos with cónyuge a cargo, attach padrón colectivo and marriage/civil partnership certificate from the start. Without them they will request it.
• For incomes, upload IRPF and also current certificates (bank, rents). The INSS wants the current year, not just the previous one.
• Got a foreign pension? Ask your foreign body for an annual statement. If it’s in another language, include a translation (better sworn if numbers are unclear).
• Scan in black & white at 150–200 dpi to reduce size and avoid the portal blocking you.

Common mistakes that can mess your application

1. Uploading only last year’s tax return: they also ask for current year income. Without it they stop the file.
2. Not proving cohabitation with a dependent spouse: without a padrón colectivo, near-certain denial.
3. Mixing up supplements: the brecha de género one doesn’t stack with the old motherhood supplement. If you switch, they may recalculate.
4. Not reporting income changes: they’ll catch you in the annual review and demand reintegro with interest.
5. Signing without saving the receipt: then you can’t prove when you submitted. Always download the PDF de registro.
