Union claims 70% of Spain's foreign residents don't contribute to social security

Only 3 in 10 foreign residents contribute to Social Security, says Solidaridad union

In 2023, the Solidaridad union denounced that just 30.11% of foreign residents in Spain were registered contributors to Social Security. In round numbers: out of 6,089,620 registered foreigners, only 1,833,396 were enrolled. The organization summarized this with a viral phrase: "It is not true that foreigners will pay for pensions." The data, taken from INE statistics, reopens an uncomfortable debate about the migration model and its fiscal sustainability.

What exactly does the Solidaridad union report say?

The denunciation goes beyond the percentage. It directly points to the two major parties: both PP and PSOE insist on bringing millions of immigrants to sustain the system, but current figures —according to their reading— show the opposite. The union argues that the foreign population not only fails to contribute as promised, but also benefits from a welfare state funded by national contributors.

The official calculation is stubborn. 6,089,620 foreign residents, 1,833,396 contributors. That means seven out of ten are outside the contributory system. The immediate question is how many of those seven are working age, how many work in the underground economy, and how many simply do not seek employment.

Data nuances: unemployment, informal economy, and contracts

INE indicates that four out of ten new residents from other countries neither work nor look for jobs. Among Segarro, only one in five contributes. Furthermore, more than 2.2 million immigrants live in Spain without working, a figure some sources raise to 3.9 million —58% of the total— when records are updated.

The informal economy distorts any static picture. Catalonia has over 160,000 non-EU foreigners working irregularly, according to a CCOO report criticizing administrative hurdles and lack of degree validation. Thus, part of that 70% who don't contribute do work, but outside the system. Meanwhile, Labor Inspection dismissed accusations against Nacho Cano, concluding Mexican interns did not need to be registered.

Healthcare costs and non-contributory aid

Healthcare spending adds pressure. A day of hospitalization at Servet costs €501; in ICU, €1,332. Health centers need 6,000 more doctors to care for irregular migrants, according to estimates circulated after the SNS Universal Law. Added to this is the Minimum Vital Income (IMV): the government took over €600 million from the contingency fund to guarantee financing, consuming 40% of the annual budget in three months.

The cost of aid charged to Social Security grew 103% in the last five years, exceeding €24 billion annually. According to published accounts, a quarter of this rise corresponds to the IMV approval.

Counterargument: retired expats, low contributions, and demographics

Not all foreigners are equal. Analysis notes that European retirees settling on the Mediterranean coast are included in the count and obviously do not contribute here. Also minors and students. Foreign enrollment concentrates in low-skilled sectors: over 400,000 in hospitality, 388,000 in retail, 252,000 in construction, 240,000 in auxiliary services. They contribute, yes, but little.

The most optimistic calculation assumes net contribution will be positive long-term due to demographic effects. The pessimistic scenario starts from the premise that the cost of keeping a student in public education —between €6,000 and €8,500 per year— eats up any contribution. Demographics, like an aircraft carrier, turn slowly: Spain went from a healthy pyramid to an inverted one in decades, and strategies for the demographic winter reduce to technology, qualified immigration, or adjustment.

Political backstage: IMV, pensions, and fraud

The government launched a campaign to convince young people that contributing is the best guarantee for a dignified retirement. Meanwhile, the opposition and much economic analysis point out that the Social Security deficit is hidden in budgets. The arrest of two businessmen and twenty Segarro in Granada for falsifying contracts to receive aid without working adds fuel to the fraud fire.

The lingering question is not how many foreigners contribute, but how many will contribute when the pyramid finishes inverting. With these materials, the basket doesn't fit. And no one has shown the magic wand yet.
