European Parliament backs new EU social security coordination rules: what changes for employers posting staff across borders
The European Parliament held its final plenary vote in Strasbourg on the 7th of July, 2026, backing a revised regulation on the coordination of EU social security systems, a reform under negotiation since the European Commission first proposed it in 2016. Parliament’s Employment and Social Affairs Committee had already endorsed the political agreement with the Council on the 22nd of April, 2026. The Council still needs to give formal sign-off, and the consolidated legal text was not yet published at the time of writing, but the substance is settled. The changes affect an estimated 16 million Europeans working cross-border, and matter directly to any employer posting staff to or from Denmark or managing employees across more than one member state.
Posted workers: tighter conditions on Article 12
Article 12, which lets an employer keep a posted worker on their home country’s social security system for up to 24 months, is staying, but the conditions around it are tightening. A worker must now have been affiliated to social security in the sending country for at least three months before the posting starts, up from one month today. Early readings of the agreed text also point to a longer gap before a worker who completes a full 24-month posting can be sent again, also up from one month; the exact figure needs confirming once the consolidated text is published. Both changes target the letterbox company practice of posting staff abroad with minimal genuine attachment to the home system, then rotating them to keep the arrangement running.
The regulation also introduces mandatory prior notification: the sending state’s authority must be told in advance of a posting. Tied to this, the A1 certificate itself must be in place before the worker departs, not applied for once the posting has already started, which has often happened in practice under the current rules. Business trips and activities of up to three consecutive days in a 30-day period are exempt, except in construction, which the rapporteur excluded from that exemption because of its fraud exposure.
The A1 certificate must be in place before departure
The A1 certificate itself must now be in place before the worker departs. Under the current rules, it is common practice to apply for an A1 after a posting has already started; the revised text closes that gap by tying the certificate directly to the new notification deadline.
Article 13: clearer rules for working in two or more member states
For employees working across more than one member state, the reform sets out the specific factors for determining an employer’s “registered office or place of business”, the anchor point for which country’s social security legislation applies: where essential decisions are taken, where turnover is generated, and where general meetings are held. This closes the loophole of pointing to a nominal registered address with little real activity behind it.
Unemployment benefits also change
The same anti-abuse logic runs through the rest of the reform. Unemployment benefit responsibility now follows the state where someone last worked for at least one uninterrupted month, which determines where a departing cross-border employee claims benefit, and jobseekers can take their benefit with them for six months while looking for work in another member state. The reform also restructures the coordination of family and long-term care benefits, changes with limited direct impact on employers.
What this means for employers
None of this applies immediately: the Council still has to adopt the text formally, and a regulation of this scope typically carries a transition period. But the direction is fixed. Review any posting arrangement that rotates staff to keep working under Article 12 against the tightened affiliation and re-posting rules, build in earlier prior notification (especially in construction, where the short-trip exemption does not apply), and check that your documented “place of business” would hold up under Article 13’s new criteria.
The requirement to have the A1 certificate in place before departure is the one to plan around now. An incorrect or late A1 certificate creates dual social security liability, backdated contributions, and disputes with two authorities at once, and that risk only grows once “before departure” is the rule rather than a best-effort guideline. We handle A1 certificate applications and cross-border social security coordination for employers with staff moving to, from, or through Denmark, and we are tracking the Council’s formal adoption as the file progresses.
Book a meeting to review how the revised Article 12 and Article 13 conditions apply to your current postings.
