EN The second pillar attracts most of the attention when planning a move to Spain. AHV, by contrast, is often seen as something already settled: a Swiss pension, paid for life, with no particular complications. That idea is not wrong — but it is incomplete, and it overlooks two points that can have a real impact on the amount ultimately received.
The AHV pension continues to be paid abroad — but not all related benefits
The AHV old-age pension itself can be paid abroad: living in Spain does not deprive a Swiss retiree of their basic pension, which continues to be paid as normal.
What changes, however, are certain benefits that may accompany AHV. Supplementary benefits, the helplessness allowance and the AHV assistance contribution are not paid to people residing abroad. A retiree who relies on one of these benefits in addition to their pension must therefore take into account, before leaving Switzerland, that these payments will stop when they move to Spain.
The risk of contribution gaps
To receive a full AHV pension, a complete contribution period must have been completed between 1 January following the 20th birthday and the end of the year preceding the reference age. This contribution period depends in particular on the year of birth and, during the transitional phase of the AHV 21 reform, may still differ for some women. In the long term, the full contribution period is 44 years.
Each missing contribution year generally results in a reduction of at least 1/44 of the pension, or around 2.3%. This is not a purely symbolic reduction: even a few contribution gaps can permanently turn an otherwise full pension into a partial pension.
The key question therefore becomes: what happens to contributions after moving to Spain, particularly for someone who leaves Switzerland before reaching the reference age?
Voluntary AHV/IV insurance does not apply when moving to Spain
This is one of the most frequently misunderstood points — and one that clearly distinguishes a move to Spain from a move to a country outside Europe.
Swiss nationals who leave Switzerland and settle outside the European Union and EFTA may, under certain conditions, join the voluntary AHV/IV scheme. This allows them to continue paying contributions from abroad and thereby avoid contribution gaps.
This option is not available when moving to Spain. Because Spain is a member of the European Union, the coordination rules between Switzerland and the EU apply instead of voluntary AHV/IV insurance. In practical terms, someone who moves to Spain cannot simply continue paying voluntary contributions into the Swiss AHV from their new country of residence. Their social security coverage then depends on their individual situation and on the system applicable in their country of residence or employment.
This is a fundamental difference compared with destinations outside the EU/EFTA and one reason why the timing of a move should not be based solely on property or tax considerations: it can also have a direct impact on the future AHV pension.
Why the timing of the move matters as much as the destination
Three concrete situations illustrate why this issue should be considered in advance:
- leaving Switzerland several years before the reference age without gainful employment may end coverage under the Swiss AHV system and create gaps in the Swiss contribution record;
- moving at retirement, once the reference age has been reached, generally has no impact on the contribution period already acquired;
- a career already affected by interruptions, for example due to education, career breaks or self-employment, makes each additional missing contribution year proportionally more significant.
The difference in the final pension amount can therefore be significant depending on the situation — without there being one single rule that applies to everyone.
Common mistakes
- assuming that the AHV pension and all related benefits can be paid abroad in the same way;
- overlooking the fact that leaving Switzerland before the reference age may create a contribution gap;
- believing that voluntary AHV/IV insurance can fill that gap once living in Spain;
- treating AHV as secondary to the second pillar, even though both are part of the same relocation timeline.
The Switzerland → Spain strategic audit to integrate AHV into the relocation timeline
At Immo Matas Suisse, the Switzerland → Spain strategic audit helps place AHV alongside the second pillar, tax residence and assets, rather than treating it as an isolated issue.
The aim is not to replace a compensation office or individual pension advice, but to identify before departure whether the planned timeline creates exposure — such as contribution gaps or the loss of supplementary benefits — that should be checked before a final decision is made.

Frequently asked questions
Is the AHV pension still paid to a Swiss retiree living in Spain?
Yes. The AHV old-age pension continues to be paid abroad. Supplementary benefits, the helplessness allowance and the AHV assistance contribution, however, are not paid to people residing outside Switzerland.
Can leaving Switzerland before the reference age reduce the AHV pension?
Yes. A missing contribution year generally leads to a reduction of at least 1/44, or around 2.3%, depending on the applicable contribution period and pension scale.
Can you join voluntary AHV/IV insurance when moving to Spain?
No. Voluntary AHV/IV insurance is intended, under certain conditions, for people living outside Switzerland, the European Union and EFTA. A move to Spain falls under the coordination rules between Switzerland and the European Union.
Do you need to wait until the reference age before moving to Spain without affecting AHV?
Not necessarily. However, a move before the reference age should be assessed on a case-by-case basis, taking into account the contribution record already completed and any potential employment activity in Spain.
