Applying for an A1/(E)101 certificate online

Employers

Using TWinternet, you can apply for an A1/E101 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, can also 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 send you a letter with your login details the following work day. Please bear in mind that the letter may take 3 to 7 days to reach you. Keep your login details in a safe place.

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.

Employers based outside the Netherlands and self-employed persons

Online applications are not possible for companies based outside the Netherlands or self-employed persons.
In these cases, you can download an application form using one of the links below and send it in by post. The form is a PDF file, so you will need Acrobat Reader to open it.
