For Social Security, the amount of the retirement pension depends on both the contribution bases and the total of quoted years. That is, the more years we have, the greater the corresponding percentage of the regulatory base, so any additional contribution will always be welcome. In this sense, although since January 1, 2024, all students who carry out training practices, whether paid or not, are registered in Social Security and quoting, who would have carried out the practices prior to that date did not have that possibility. For them, the General Social Security Treasury has enabled a special agreement that allows recovering up to five years of contribution, regulated in the ISM/386/2024 order.
To understand it better and first hand, Alfonso Muñoz Cuenca, the Social Security official specialized in benefits and pensions, explained in his YouTube channel how this measure works. “Many of you have asked me if it is worth signing this agreement taking into account the economic expense that it supposes. The first thing is to know how much it will cost and how it can be paid.”

Up to five years of recoverable contribution
The regulations establish that periods of practices carried out before January 1, 2024 (if they were unpaid) or before November 1, 2011 (if they were remunerated) may be computed. The maximum that can be recovered is 1,825 days, equivalent to five years.
Of course, only the time really invested in practices is recognized: “If we have been a year, we can recover a year of price; if there were two, two years, and so on up to five,” Muñoz points out.
How much does it cost and how it pays
The cost is not calculated with the minimum base of 2025, but with the minimum contribution base that was in force in the year in which the practices were carried out. The type of contingency for common contingencies is applied to that base and, subsequently, a reducing coefficient of 0.77, which decreases the final amount. “It is advisable to go to the Treasury with the certificate of the practices to tell us in our specific case how much it will cost,” Alfonso explains in a easily and easily.
Regarding the payment of the fees, these can be made at a single payment the month following the signing of the agreement or fractioning the payments. “If we are going to recover a year, it can be paid in 24 monthly payments, and with a maximum of 84, that is, seven years,” Muñoz explains.
Deadline for signing the agreement
The application can be submitted until December 31, 2028. This allows each person to decide when it is more economically convenient. “It is not necessary to do it now, you can wait for a better situation,” says the official.
The petition is processed before the General Treasury of Social Security, providing the certification of the practices issued by the University, Educational Center or company in which they were carried out.
Is it worth signing this agreement?
The answer, according to Muñoz, is prudent: “No one can assure you that these quotes serve you tomorrow, but you should take into account some data.”
First, for the retirement pension they are asked to have at least 15 years quoted and to be 100% of the pension it is necessary to have 36 and 6 months quoted. On the other hand, the retirement age will reach 67 years in 2027, although if we are 38 and 6 months quoted we can retire at 65.
In the case of wanting to retire in advance, it is necessary to know that a minimum of 33 years quoted for the involuntary or 35 years quoted voluntary is necessary and to access the permanent disability, a minimum of contribution is also required, between 5 and 15 years, depending on the age of the worker.
In conclusion, “the more years of contribution we have, the greater the protection we will have and more options to collect a retirement before and of greater amount,” Muñoz summarizes.
