EU Social Security Coordination Reform

EU social security coordination is changing

After nearly a decade of negotiations, the EU Council and European Parliament reached a provisional agreement on 22 April 2026 to revise Regulations 883/2004 and 987/2009 — the core framework governing social security coordination across Europe.

‍

This is not simply a technical update. It is a targeted modernisation of rules that no longer fit today’s reality of short-term postings, multi-state work and large cross-border commuter populations. The direction of travel is clear: more legal certainty, tighter administration and stronger enforceability.

‍

Why this reform matters now

For employers, the practical significance lies less in theory than in process. The revised framework puts more emphasis on prior notification, standardised documentation, data exchange between institutions and clearer allocation of financial responsibility between states. In other words, cross-border social security is moving away from flexible interpretation and towards a more structured compliance model.

‍

What is changing — and why it matters

Five areas stand out for employers with mobile workforces.

‍

1. Posted workers and A1 certificates

The A1 certificate is the attestation confirming which country’s social security system applies in a cross-border working situation. Under the revised proposal, prior notification becomes the norm. If the certificate cannot be issued immediately, the institution must issue an acknowledgement of receipt as proof that the notification requirement has been met.

‍

The proposal also reinforces the home-state link. For recruited employees, a minimum period of 3 months prior affiliation is required before the posting begins. The revised text further clarifies that, outside business trips, very short activities of no more than three consecutive working days may be exempt from the prior-notification rule — but not in the construction sector. Construction is treated separately because the proposal associates it with a higher concentration of postings, more frequent fraud and abuse risks, and a higher incidence of accidents.

‍

2. Unemployment benefits

Unemployment is the most politically and financially significant part of the reform. The proposal seeks to create a stronger link between the labour market that received the worker’s contributions and the state that pays the benefit. For wholly unemployed cross-border workers, the competent state will be the state of last activity if the worker completed an uninterrupted period of at least 22 weeks there during the last activity. If that threshold is not met, the residence state remains relevant under the revised derogation.

‍

The proposal also harmonises aggregation rules, introduces a one-month uninterrupted period requirement for certain claims, and allows Member States to extend the export of unemployment benefits beyond six months up to the end of entitlement.

‍

3. Long-term care benefits

Long-term care is one of the clearest legal clarifications in the package. The proposal defines long-term care benefits as benefits in cash or in kind intended to address the care needs of a person who requires considerable assistance with essential daily activities over an extended period. Until now, these benefits were not expressly included in the Regulation and were generally coordinated by analogy with sickness benefits, which created uncertainty.

‍

The revised text brings long-term care explicitly into scope, adds a dedicated framework and introduces rules for overlapping benefits in cash and in kind. It also provides for a list of qualifying long-term care benefits to be drawn up at EU level. The practical result is greater predictability for both institutions and claimants.

‍

4. Family benefits

The family-benefit changes are more technical, but still important. The proposal distinguishes between family benefits intended primarily to replace income during child-raising periods and those intended to cover general family expenses. The revised text introduces a dedicated Article 68b and a new Annex XIII. Under this structure, income-replacement child-raising benefits are treated as individual rights of the parent subject to the competent legislation. Certain Member States may also elect, if listed in the Annex, to award those benefits in full regardless of the amount payable elsewhere.

‍

5. Digitalisation and anti-fraud measures

The revised proposal places clear emphasis on digital administration and stronger enforcement. It requires Member States to make requests for the determination of applicable legislation accessible fully online, including automatic acknowledgements of receipt where the final output is not immediate.

‍

On anti-fraud, the text creates a clearer legal basis for authorities to exchange and compare data in order to detect fraud, error and inconsistencies, subject to data-protection safeguards. The overall message is straightforward: enforcement will become more systematic, faster and more evidence-based.

‍

Switzerland — the most exposed non-EU country

Switzerland is particularly exposed because of its large cross-border workforce and its integration into the EU coordination framework through the EU–Switzerland arrangements. The changes to unemployment, A1 administration and cross-border verification are therefore especially relevant. For Swiss employers, the proposal is not only a regulatory development to monitor — it is a shift that may affect cost, process design and workforce planning.

‍

What employers should do now

The prudent approach is to prepare before the final text enters into force. Employers should review the structure of their cross-border population, reassess A1 and posting procedures, identify where unemployment exposure may sit under the revised rules, and build these changes into mobility decisions planned from late 2026 onwards. This reform does not require immediate structural redesign, but it does require earlier assessment and tighter process control.

‍

Final thought

The regulation still requires formal adoption. But from a compliance perspective, the message is already clear. The revised framework is designed to make cross-border social security more transparent, more digital and more enforceable. Employers who prepare now will be in a stronger position to manage the transition; those who wait may find that the operational consequences arrive before the legal debate has fully settled.
