For employers sending staff abroad, compliance is more than paperwork—it’s about avoiding costly fines and protecting workers. In the EU, the A1 Certificate is the document that ensures you only pay social security contributions in the home country, not twice.
Failure to comply with A1 rules can result in penalties for both employers and workers. Here’s what every business needs to know.
What Is the A1 Certificate?
The A1 Certificate confirms which country’s social security system applies when a worker is temporarily assigned abroad within the EU/EEA or Switzerland.
It’s mandatory for posted workers, whether the assignment lasts a few weeks or up to 12 months (extendable to 18).
Why Non-Compliance Leads to Fines
- Double contributions if no A1 is presented
- Legal penalties from host country authorities
- Project delays if workers are stopped during inspections
- Risk to workers’ benefits like healthcare and pensions
Employer Responsibilities
- Apply before departure – workers must carry the A1 from day one.
- Provide accurate details – contracts, duration, and role must be correct.
- Renew on time – extensions require fresh approval.
- Keep a copy accessible – authorities can request it during checks.
Where to Apply
In Portugal, the A1 is issued by Segurança Social.
