International secondment - Applying for an A1/(E)101 certificate

Employers

Using TWinternet, you can apply for an A1/(E)101 certificate quickly and easily online. Compared to the paper form, there are far fewer details to fill in, and you will normally hear from us within a week. You can also track your application online.

Your representative, e.g. your tax consultant, will also be able to submit an application online.

If your company does not yet have an account for online applications, or if you have forgotten your password or username, you can apply to us for an account or a new account. We will then send you a letter with a password and username the following work day. Keep your login details safe and secure.

Authorization

If you, as an employer, have appointed a representative, you and your representative can both use your user name and password. In that case, we will not need a separate authorization.

However, if your representative also acts on behalf of your employee, we will need a signed authorization from your employee. You should send in the authorization by post, stating your employee's Burgerservicenummer (BSN). Also state that the authorization is provided in connection with an application for an A1/(E)101 certificate.
We advise you to send in the autorization one week before sending in your application for an A1/(E)101 certificate. This will enable us to process your application quickly.

NB: you need to send in an authorization with every new application.

Different procedure for employees living outside the Netherlands

If your employee does not live in the Netherlands, and will be working in two or more EU Member States (including the Netherlands), you need to apply to the competent authority in the employee's country of residence for a certificate stating that there are no objections to your employee being covered by Dutch social insurance. You can then apply to us for an A1/(E)101 certificate within two months, using a paper form and enclosing the statement by the non-Dutch competent authority.

Download, print and send the form in by post

Self-employed persons and companies based outside the Netherlands cannot use the online application procedure. Instead, you can download the applicaton form using one of the links below, and send in the form by post. The form is in PDF format. To read a PDF file, you need the program Acrobat Reader.

Online applications do not get special priority.
