A1 telework certificate transition period ends 30 June 2026

The transition period for A1 social security certificates issued under the cross-border telework framework expires on 30 June 2026. Employers with staff teleworking across EU borders need to file extension applications now to avoid gaps in social security coverage.

The framework, which now covers 23 signatory countries following Estonia’s accession in February 2026, allows employees to telework up to 49% of their time from their country of residence while remaining covered by their employer’s home-state social security system. Certificates issued during the 2023-2026 transition period were temporary, and those that have not been renewed will lapse at the end of June.

This is a critical compliance deadline for employers with cross-border remote workers. A lapsed A1 certificate could mean the employee falls under the social security system of their residence country, triggering double contributions or unexpected liabilities. HR teams and payroll providers should audit their cross-border telework arrangements and submit renewal applications well before the 30 June deadline.
