CSI — complemento solidário para idosos (pension top-up for older people)

A top-up to a small pension for people who have reached normal pension age, have lived in Portugal for at least six years and have an income below a set threshold. It takes into account the person's own income and, for those who are married or have lived in a de facto union for more than two years, their spouse's or partner's income too. Children's income has not been counted since 1 June 2024 (Decree-Law 35/2024). The top-up was introduced by Decree-Law 232/2005.

Where you come across it. A pension below the subsistence threshold; help for elderly parents.
This top-up is NOT part of the prestação social única (PSU) and remains a separate payment: people moved onto the PSU from 31.12.2026 continue to receive it (Article 57 of Decree-Law 166/2026).
