What is an A1 certificate?
An A1 certificate (certificate of coverage) shows that your employee will stay insured in the Netherlands if they are going to work outside the Netherlands temporarily.
It is important that your employee has an A1 certificate. Without it, they will probably not be able to work in the other country.
An A1 certificate will stop being valid if:
- your employee starts working in the Netherlands again
- the company in the other country (to which your employee was posted) sends the employee to work in a different company
