What is INSS 6-065 — Voluntary IRPF withholding on a pension?

Form 6-065 is published by the Instituto Nacional de la Seguridad Social (INSS). A pensioner uses it to ask for a voluntary IRPF withholding rate on their Social Security pension, or to end one. The form says a voluntary rate must in any case be higher than the rate applied to your pension now. The current edition is 6-065 cas V.8 of 27 July 2023.

To end a voluntary rate you choose whether it ends for the next tax year, or for the current year if the voluntary rate started in an earlier year. The form explains that the new rate will then be the one that follows from your communication of personal and family situation, which is the basis for the withholding under the IRPF law.

FileIt explains every box in English, checks DNI and NIE letters, and prints your answers neatly onto the INSS's official PDF, including names with letters such as ł, ș or ü. The finished form is saved in your FileIt vault. FileIt never sends anything to the INSS.

How to fill out INSS 6-065 — Voluntary IRPF withholding on a pension, step by step

1 1. Datos del pensionista (the pensioner)

Your surnames, name and DNI, NIE or passport. The address and contact details only if they changed since your last communication.

2 Solicita: el tipo voluntario (ask for a voluntary rate)

Tick 'El tipo voluntario' and give the percentage to apply. It must be higher than the rate applied to your pension now.

3 Solicita: finalización (end the voluntary rate)

Or tick 'Finalización de aplicación de tipo voluntario' and choose from the next tax year, or from the current year if the voluntary rate started in an earlier year.

4 Declaro, consentimientos y firma (declaration, consents, signing)

You declare the data are true, and say whether the INSS may consult your data with other administrations and use your contact details for Social Security communications. Then the place, date and the INSS provincial office. Sign under 'Firma del interesado' unless you file online.

Common mistakes to avoid

  • Asking for a rate that is not higher than the one applied now. The form says a voluntary rate must be higher.
  • Ticking both boxes. Choose either a voluntary rate or its end.
  • Ending a voluntary rate for the current year when it started this year. The form allows that only if it started in an earlier year.
  • Refusing the data consult without being ready to send documents: the form says you then have 10 working days to provide what the INSS asks for.
