Brexit: «Mind the Gap»
The United Kingdom’s exit from the EU (Brexit) was triggered by the British referendum on June 23, 2016. With the signing of the withdrawal agreement on January 31, 2020, the exit from the EU at the end of 2020 was sealed. The bilateral treaties between Switzerland and the EU are therefore no longer applicable to the United Kingdom as of January 1, 2021.
Impact on migration and social security laws
Brexit and Switzerland
Between 2016 and 2019, an average of 4,200 Britons have migrated to Switzerland each year. While compared to previous years, the number has decreased as the EU has become a more attractive immigration location due to its freedoms of services and establishment; UK nationals still form about 2.6% of the total number of immigrants to Switzerland per annum. In addition, in year 2019 around 3,800 people were posted from the UK to provide services in Switzerland.
Therefore, the Federal Council pursued the so-called «Mind the Gap» strategy, with which it contemplates avoiding gaps in the legislative framework and maintaining mutual rights and obligations. In the areas of migration and social security law, however, this is largely limited to preserving rights that have been created (up) until December 31, 2020. The rules of the game have, however, changed as of January 1, 2021.
Whereas British nationals were previously able to benefit from the free movement of persons, they are now subject to the general provisions of the Foreign Nationals and Integration Act (AIG). Exceptions relate, on the one hand, to the rights that have been acquired until December 31, 2020, as set out in the agreement between Switzerland and the UK and, on the other hand, to the provision of services for up to 90 days according to the agreement on cross-border mobility.
The following overview shows, in a simplified manner, the rules that are now applicable in the area of migration law:
Entry of UK nationals into Switzerland until December 31, 2020 = UK nationals with acquired rights (“grandfathering”):
- Continuation of the following (acquired) rights:
- Residence with gainful employment
- Residence without gainful employment
- Right to family reunification (however, limited until December 31, 2025)
- Cross-border activity
- Discontinuation of the rights if the prerequisites are no longer met (e.g. emigration, danger to public order).
UK nationals entering Switzerland from January 1, 2021 on = new UK nationals entering Switzerland:
- No visa requirement
- Gainful employment in Switzerland requires work permit under the same conditions as those applicable for other third-country nationals (according to AIG); special quota of 2,100 B permits and 1,400 L permits
- Provision of services for up to 90 days per calendar year: application of the notification procedure without review by the Swiss labour authorities; applies to companies based in the UK regardless of the nationality of the posted employees, provided they have been admitted to the regular UK labour market for at least twelve months
- Residence without gainful employment (e.g. relocation of wealthy individuals): rules according to AIG applicable
Coordination of social security systems
While the UK was a member state of the EU, the rules pursuant to Regulations (EC) No. 883/2004 and (EC) No. 987/2009 on the coordination of social security systems were applicable. However, these are no longer relevant in relation to the United Kingdom as of January 1, 2021. Apparently, Switzerland and the United Kingdom contemplate providing for new coordination rules. However, the corresponding agreement has not yet been finally negotiated. Until then, the current bilateral social security agreement between Switzerland and the UK will apply.
The following overview shows, in a simplified manner, the different rules with regard to the coordination of social security systems:
Cross-border situations related to the EU, the UK and Switzerland that had started (up) until December 31, 2020, create acquired rights:
- Group of persons for whom there will be no change regarding their social security coordination for as long as these persons are in a cross-border situation (i.e. as long as there is a connection to both states and, if applicable, additionally to an EU member state, due to nationality, activity or residence):
- UK nationals in a cross-border situation between Switzerland and the EU
- Swiss nationals in a cross-border situation with the UK and the EU
- EU nationals in a cross-border situation between Switzerland and the United Kingdom
- Other persons who are not (any longer) in a cross-border situation for as long as they have the right to work or reside in the other state (e.g. CH nationals who continue working in the UK after their secondment in the UK or who give up their employment in the UK but remain resident there)
- Applicable social security system:
- The same state continues to be responsible for social insurance, collects contributions and provides benefits without discrimination
- A1 certificates concerning cross-border situations that started before January 1, 2021 remain valid for the duration of the cross-border situation or the duration of the validity of the A1 certificate, respectively
Cross-border situations involving the EU, the UK and Switzerland starting from January 1, 2021:
- Posting of UK nationals or third-country nationals (i.e. non-EU/UK/CH) between Switzerland and the UK: application of the bilateral social security agreement of February 21, 1968
- Posting of UK nationals between Switzerland and the EU: Application of the bilateral social security agreements between Switzerland and the EU state concerned (if applicable)
- Cross-border situations outside of a posting: Application of the bilateral social security agreement of February 21, 1968 with regard to CH and UK nationals, but not with respect to other nationals
For companies wishing to employ British nationals, Brexit means that – unlike in the past – they will first have to go through the ordinary work permit application procedure. Even if the number of available permit quotas may be sufficient to cover demand in 2021, this means an additional administrative burden for HR departments and a longer planning period when relocating employees. Finally, this also leads to a certain degree of planning uncertainty, as there is no legal entitlement to the issuance of permits under this quota.
Since January 1, 2021, there is a patchwork quilt regarding several questions that have remained open with respect to the coordination of social security systems. It can only be assumed that, the social security authorities have not made an effort providing more clarity by publishing guidelines or the like in light of the probably impending conclusion of a new, comprehensive social security agreement between Switzerland and the UK which will presumably rely heavily on the existing EU rules. However, for the time being, this means considerable legal uncertainty, especially for HR departments. Hopefully the negotiating partners will succeed in quickly concluding a new, comprehensive social security agreement.
