What happens without a valid A1 form?
Inspection risk
Employees can be stopped from working. Employers face fines, penalties, and delays.
Double contributions
You may be required to pay social security in two countries. The A1 is the only safeguard.
Rework and delays
Incorrect applications get rejected, causing delays and added scrutiny.
Requirements for an A1 form
To secure an A1 form, you typically need to show:
- Proof of home country social security coverage
- Evidence of employment (contract and payroll)
- Assignment details (location, duration, work scope)
- Confirmation the employee remains under the home employer
- Any country-specific documents (e.g. translations or forms)
We confirm the exact requirements during your initial consultation.

Speak to our team to understand whether an A1 is needed, what is required, and how to get it in place.
Book a call
Yes, in most cases. The requirement applies to any work activity in another European country, including single-day visits, client meetings, and conferences. Duration is not the trigger; work activity is. If the employee is performing work while physically present in the host country, you should have an A1 in place. We confirm the specific position for your situation during the call.
It can. If an employee is working remotely from another European country – including informally, such as working while visiting family – this can trigger the A1 requirement. The test is whether work is being performed in the host country, not where the employer is based or where the contract is governed. We assess your specific situation during the call.
The most useful things to have ready are: the home country of employment and social security registration, the host country or countries, the dates and expected duration, the nature of the work activities, and the employment status. You do not need everything at the start; we work through the details with you.
Timelines vary by issuing country. Some home-country authorities process applications within a few working days; others take several weeks. We give you a realistic timeline for your specific situation during the assessment. As a general rule, it is worth starting the process well before the employee travels.
Yes. We support businesses managing A1 requirements across multiple host countries and can handle volume where regular cross-border travel is part of the business. The Centuro platform gives you visibility across your full cross-border population so you can track what is in place and what needs renewal.
Local labour inspectors in many EU countries actively check for A1 documentation, particularly in construction, logistics, and professional services. Without an A1, the employer can face fines, retroactive social security claims from the host country, and mandatory compliance remediation. We do not provide legal advice on enforcement outcomes, but we can help you get compliant before that situation arises.
No. This service is for businesses and employers. If you are an individual looking to manage your own A1 application independently, this is not the right service for you.
Your legal team handles the advice; we handle the execution. We manage the requirements checklist, document preparation, submission, authority correspondence, and recordkeeping, freeing your team to focus on decisions rather than administration. We also provide platform visibility across your full cross-border population, which most law firms do not offer.
