Complemento Solidário Para Idosos Climbs to 239,771 Beneficiaries in March 2026 — 11% Year-on-Year Growth as the Reference Value Marches Toward €870 by 2029

The Gabinete de Estratégia e Planeamento (GEP) at the Ministério do Trabalho, Solidariedade e Segurança Social published its monthly read on Portugal's headline anti-poverty transfer for older residents on Friday: 239,771 people drew the Complemento Solidário para Idosos (CSI) in March 2026, up 1,921 on February (+0.8%) and up 23,769 on March 2025 (+11.0%). The average payment hit €217.43, a 7.1% rise on the same month a year earlier.

The CSI is the means-tested top-up that supplements lower-income retirees' total resources to a published reference value. Beneficiaries must be 66 years and three months old or older (the current statutory retirement age), legally resident in Portugal, and have annual resources below the threshold. The supplement is paid 12 times a year — there is no holiday or Christmas double month — and is non-cumulative with most other social-action subsidies.

Why the cohort keeps growing

Two policy changes are doing the heavy lifting behind the 11% year-on-year jump in beneficiaries. The first is the multi-year ramp of the reference value itself. Lei n.º 28/2024 set out a glide path that lifted the threshold to €670 per month for 2026 and writes in further annual increases targeting €870 by 2029, a level designed to track the at-risk-of-poverty line for one-person households. Each notch up the ladder pulls a fresh band of low-income retirees into eligibility.

The second change, in effect since 2024, removed adult children's income from the family-resources calculation used to test eligibility. Under the previous rules, an applicant's children's earnings counted toward the household total, which excluded thousands of older parents whose grown-up children earned modestly above the cap. Stripping that variable out widened the gate sharply — and is the cleanest explanation for why beneficiary numbers have run well ahead of demographic ageing in the last two years.

Who actually receives the supplement

GEP's March cut shows the CSI cohort is overwhelmingly female. 156,089 of the 239,771 beneficiaries — 65.1% — are women, a structural skew that reflects three things: women's longer life expectancy, lower lifetime contributory pensions tied to interrupted careers and the gender pay gap, and the higher prevalence of widowhood in the over-66 bracket. The 7.1% year-on-year rise in the average payment is largely the mechanical pass-through of the higher reference value — when the ceiling moves, top-ups for everyone below it scale with it.

For perspective, March's 239,771 beneficiaries compare with roughly 217,000 in March 2025 and a low of about 165,000 in 2018. The programme has now climbed for eight consecutive years, with the steepest acceleration in the period since the 2024 eligibility-rules reform.

What it means for foreign residents and family members

The CSI is open to foreign residents on the same terms as Portuguese nationals, provided they meet the residency, age and resources tests. For older expats living on modest pensions converted from sterling, dollars or other currencies, the supplement can be a meaningful floor — particularly relevant where exchange-rate moves have eroded the buying power of a fixed home-country pension. Applications go through Segurança Social Direta or any Loja de Cidadão; documentary requirements include proof of resources from all sources, which for expats means home-country pension statements translated and certified.

For adult expat children of Portuguese parents, the 2024 income-test reform is the structurally important point: a parent who was previously rejected because the children's salaries pushed the household over the cap may now qualify. Re-applications are worth running through if circumstances changed in the past two years.

The fiscal frame

At an average payment of €217.43 across 239,771 beneficiaries paid 12 times a year, the annualised CSI envelope is in the order of €625 million. That is small relative to the contributory pension bill, but the trajectory matters: the reference-value ramp to €870 by 2029, combined with continued cohort growth, will pull the programme's annual cost above €1 billion before the decade is out — a structural addition to the social-security budget that the next Programa de Estabilidade will have to bake in.

The next monthly print is due in early June and will show whether April's payment cycle continues the +0.8% month-on-month run or whether the new fiscal-year recalibrations smooth the curve.
