The European Union has entered into force a regulation revising social security coordination rules for workers and businesses moving across member-state borders. Most of the revised rules apply from 1 November 2028, and businesses posting staff across the EU should plan for new notification and affiliation requirements.
Why it matters
The revision aims to make social security coordination clearer, fairer and easier to enforce across the EU. It followed a provisional agreement among co-legislators earlier in 2026 and formal adoption by both the European Parliament and the Council of the EU.
The regulation covers roughly 16 million mobile EU citizens and sets concrete thresholds for posting workers, including a 3-month affiliation minimum, a 24-month posting cap and a 2-month break before re-posting. Short-term postings of up to three days are exempt from notification in all sectors except construction.
The players
European Parliament
The directly elected legislative body of the European Union, which co-adopts EU regulations alongside member-state governments.
Council of the European Union
The EU body representing member-state governments that co-adopts legislation with Parliament and coordinates national policy.
The details
Under the revised rules, a worker must be affiliated to their home-country social security system for at least three months before being posted to another EU country. After 24 months of posting, a break of at least two months is required before another posting can begin. Postings must generally be notified in advance, though business trips are excluded and very short postings of up to three days are exempt outside construction. The regulation also introduces a new definition of fraud in social security coordination and strengthens information exchange between national authorities.
Timeline
7 July 2026: European Parliament formally adopts the regulation.
28 September 2026: Council of the EU formally adopts the regulation.
5 November 2026: Regulation enters into force.
1 November 2028: Most revised rules begin to apply after a two-year adaptation period.
Market Landscape
The revision updates the EU social security coordination framework that has governed cross-border worker mobility, adding tighter posting and fraud rules. It also extends the coordination regime to Iceland, Liechtenstein, Norway and Switzerland, which are covered by the same rules.
Businesses that post staff across EU borders should review affiliation timelines, posting durations and advance-notification procedures before the rules take effect. Human resources and finance teams should map which assignments could fall under the new break and notification requirements.
The takeaway
Businesses with cross-border postings should begin mapping their current assignments against the new three-month affiliation, 24-month cap and two-month break rules well before 1 November 2028. Consult qualified employment counsel to confirm how the notification exemptions apply to specific assignments.
What happens next
Most of the revised rules begin to apply on 1 November 2028, after the two-year adaptation period.
