Request additional top-ups to your pension (INSS)

What to have ready

1. Cl@ve PIN/Permanente or certificado digital/DNIe to enter Tu Seguridad Social.
2. Número de expediente of your pension and your Número de la Seguridad Social.
3. IBAN where you get paid.
4. Income details (IRPF, interest, rents, payslips if you combine work and pension).
5. Libro de familia or birth certificates if you apply for the brecha de género complemento.
6. Certificado de empadronamiento (for residence in Spain) and documents for any other pensions you get.

Documentation

• DNI o NIE of the holder (and of spouse/partner if it affects income limits).
• Resolución o justificante of your INSS pension (shows the expediente number).
• IBAN and bank certificate if requested.
• Certificado de empadronamiento up to date (essential for complemento a mínimos).
• Income declaration: IRPF, bank certificates of interest, rental contracts and receipts, payslips if you work.
• Libro de familia/certificados de nacimiento for the complemento de brecha de género.
• Resolutions of other pensions (Clases Pasivas, abroad) with amounts.

Step by step

1. Access Tu Seguridad Social: go to https://tu.seg-social.gob.es/ with Cl@ve or certificado and open “Pensiones y prestaciones” > "Gestionar mi pensión".
2. Choose the procedure: look for "Solicitar complemento" or "Comunicar variación de datos". If it doesn’t appear, use the mailbox "Presentar solicitud/otros escritos" inside Tu Seguridad Social (this works to request top-ups and attach everything).
3. Fill and attach: state which complemento you want (mínimos, brecha de género or other), explain why (income, children, family changes) and attach clear PDFs of the documents.
4. Sign and register: validate with Cl@ve PIN/Permanente or certificado, send and save the receipt with CSV/registration number.
5. Track status and correct: in "Mis gestiones" you’ll see if they request anything. If there’s a requerimiento, upload the missing items from the same section and sign again. Resolution usually arrives in 1–4 semanas.

Tricks to save time

1. Combine PDFs: put related docs in a single file (income, empadronamiento, family). Fewer uploads, less hassle.
2. Recent empadronamiento: if it’s older than 3 months they may reject it.
3. Bank interest: ask the bank for the certificado fiscal anual; avoids problems with screenshots.
4. Keep the CSV from the registry: if something is lost, with the CSV the INSS finds your application in seconds.
5. No Cl@ve? Get it in 10 minutes via video or at an office. It’s faster than waiting weeks for a face-to-face appointment.

Common mistakes that can derail your application

1. Not proving residence: without up-to-date empadronamiento the complemento a mínimos won’t pass.
2. Omitting “small” income (€50 interest or a one-off rent): it counts. If it shows up later you’ll face a repayment with interest.
3. Uploading blurry photos of Libro de familia or resolutions: the system accepts them but INSS will require clearer copies and you lose weeks.
4. Not answering a requerimiento: if they ask for more papers and you ignore it, they archive the case and you start from zero.
5. Living abroad and asking for mínimos: it simply doesn’t proceed; they’ll deny it or withdraw it if you already had it.
