An A1/certificate of coverage is a form stating the country in which a worker is covered by social insurance. This certificate is valid in the countries of the European Economic Area (EEA) and countries with which the Netherlands has a social security agreement.
- you are an employer or intermediary based outside of the Netherlands who intends to have an employee work for you temporarily in the Netherlands
- you work on assignment in the Netherlands as a self-employed professional, while remaining based in your own country
you or your employee usually remains covered by your own country’s social insurance system. In that case, you will not have to pay social insurance contributions in the Netherlands. However, you will require an A1/certificate of coverage.
A1/certificate of coverage validity and how to apply
In many countries, a labour inspectorate checks whether you or your employee has a valid A1/certificate of coverage. You apply to your own country's social insurance institution for an A1/certificate of coverage. Check this page for more information on Health Insurance and other Social Security matters when moving within the EU.
Social insurance when working permanently in the Netherlands
If you or your employee permanently takes up work in the Netherlands, you will no longer be covered by your own country's social security system. You will then pay social insurance contributions in the Netherlands. Different rules and regulations apply if you or your employee work/works in more than one EU Member State. For more information, please contact the Dutch Social Insurance Bank (Sociale Verzekeringsbank, SVB) or the social insurance organisation in your country.
This same applies, of course, when you or your employee works temporarily outisde the Netherlands, but remains based in this country. Then you need to apply for an A1/certificate of coverage from the Sociale Verzekeringsbank (SVB).
E101 versus A1 certificate of coverage
Until 2010, the E101 form was used in the Netherlands to indicate the country in which a worker is covered by social insurance. However, since then the E101 form has been replaced by the A1 form, which is used throughout the EU Member States.
