Spain’s Ministry of Inclusion, Social Security, and Migration has recently issued a significant new regulation, allowing specific groups to have their past internship or research training periods credited as part of their work history by back-paying social security contributions. This move is seen as a crucial social justice measure, designed to rectify historical system deficiencies and safeguard the long-term welfare of workers.
Core of the New Regulation: Retroactively Credit Work History, Secure the Future
Signed by Elma Saiz, the Minister of Inclusion, Social Security, and Migration, the ministerial order’s core is the establishment of a special agreement mechanism. By signing this agreement with the General Social Security Treasury (TGSS), eligible applicants can pay the social security contributions they missed during their internships. This policy allows for the recovery of up to five years (1,825 days) of contribution records, which will directly impact the calculation of the applicant’s future pension, permanent disability benefits, and survivor allowances.
Who is Eligible? A Detailed Look at the Three Beneficiary Groups
According to the decree, this back-payment policy is primarily aimed at the following three groups:
- Unpaid Interns: Students who completed unpaid internships or academic placements in university, vocational training, higher arts, or sports education programs before January 1, 2024.
- Doctoral Researchers: University graduates who participated in doctoral research training programs before February 4, 2006.
- Certain Paid Interns: Individuals who participated in paid internships before November 1, 2011, but were not included in the social security system at the time.
Applicants must provide official documentation to prove the authenticity, specific start and end dates, and duration of their internship or training experience.
Back-Payment Costs and Payment Methods

The cost of the back-payment is not arbitrary. The calculation is based on the minimum contribution base for contribution group 7 of the General Social Security System for 2024. A reduction coefficient of 0.77 is then applied to this base to ease the financial burden on applicants.
Regarding payment methods, once the TGSS determines the total amount, two options are available: applicants can either pay the full amount in a single lump sum or opt for installment payments. The maximum term for installment payments is equal to the number of months being claimed, offering applicants financial flexibility.
Policy Significance: Correcting Inequity and Benefiting Thousands of Workers
Minister Saiz emphasized that this measure aims to correct past inequalities caused by an incomplete system, ensuring that the rights of the younger generation are not compromised by their internship experiences as they enter the labor market. By allowing internship periods to be counted as valid social security contribution years, tens of thousands of workers will be able to significantly improve their future social security coverage, giving their early career efforts the recognition and reward they deserve.
