By: Siobhan Owers, George Koureas

As a ‘No Deal’ Brexit remains a distinct possibility, companies need to understand the potential implications, especially with regard to short and long term mobility of their employees. An area of major significance which is often not sufficiently headlined is the significant impact a hard Brexit may have on the salary cost and the social security cost of the employees travelling to and from the UK, for both employer and the individual.

In principle, a worker is subject to social security contributions in the country in which they work. An important exception to this is in the case of a ‘posting’, i.e. when a worker carries out duties on a temporary basis in another country, in the interest of his/her employer, and when the worker is not replacing another ‘posted’ worker to the same entity. In such a case, a worker could maintain social security coverage in their Home country for a limited period of time, without becoming liable for additional social security costs in their Host country.

These exceptions are laid down in international social security agreements, such as the EU Regulations on the coordination of social security systems, which currently apply to all EU and EEA member states (including the UK) and Switzerland. As of Brexit day, in case of ‘No Deal’, the EU Regulations, allowing the ‘posting’ exception, would cease to apply to the UK. Therefore, the risk of an employee going between the UK and the EU becoming liable to social security in both the EU and the UK is very real.

 ‘Old’ Bilateral Social Security Agreements

In principle, one solution to the social security challenges post ‘No Deal’ Brexit could be reviving the existing ‘old’ social security agreements that the UK concluded with a number of  EU  member states in the past. The legal validity of their revival is a legal question, which is still being debated in many countries. However, even if such agreements were deemed still valid, consideration must be given as to whether they can be easily adapted to reflect the dynamics and characteristics of the modern day mobile workforce.

Domestic Social Security Legislation

In the absence of any ‘old’ bilateral social security agreements, and unless new ones are made, the UK will be treated as a non-EU country from a social security perspective by the EU member states. This means that the social security implications in a cross border work situation would need to be addressed by looking at both the domestic legislation of the sending country as well as the domestic legislation of the receiving country.

For example, a UK worker ‘posted’ to  France for a temporary period of time could become liable to French high-cost social security contributions, in addition to having continuing liability in the UK. Moreover, depending on the individual circumstances of the actual cross-border employment set-up, the posted worker may also not reach minimum social contributions to qualify for future pension benefits in the UK or France. In most jurisdictions, the social security contributions paid into the system during a period of work cannot be refunded at the moment of departure from the country at the end of the posting period.

Next Steps

With informed advance planning, companies can put strategies in place to avoid a ‘No Deal’ or hard Brexit becoming an overwhelming experience. A solid strategy can also help to manage the impact and expectations of their workers in relation to social security and protect salaries (and salary costs) from being impacted by a change in social security costs.

To minimize the significant cost impact of a ‘No Deal’ or hard Brexit on the social security cost of a mobile workforce, and the potential need to compensate for the loss of social security entitlements (e.g. pension rights, protection of access to medical care), companies need to assess the implications, plan in advance and inform internal stakeholders appropriately:

  • Assess: Conduct an in-depth internal analysis of the posting status quo to understand potential negative social security implications such as double liability costs could be mitigated by adjusting the contractual arrangements and assignment structures.
  • Plan: Prepare hypothetical cost projections reflecting the most frequently occurring cross-border traveller profiles and patterns.
  • Inform: Continuous communication with internal stakeholders, line managers, HR, global mobility, finance, and frequent business travellers is critical in creating awareness around the impact of Brexit on social security and to budget for increased costs, stricter compliance and increased reporting.
Fragomen can help your company through the integration of our contingency ‘No Deal’ Brexit planning initiatives in the area of both Immigration and Social Security.
