How to apply for an A1/certificate of coverage
Applying for an A1/certificate of coverage online
The quickest way to obtain an A1/certificate of coverage is by using TWinternet. Compared to the paper form, you do not have to fill in as many details, and you will normally hear from us within a week. You can also track your application or extend a secondment period online.
It is also easy for a representative, e.g. your tax consultant, to submit an application online.
If your company does not yet have an account for online applications, you can apply for one. A few days after you have chosen a username, you will receive a letter from us containing your password. Keep your login details safe.
If you are a director and major shareholder (DGA), or if you work for your own private limited company (BV)
If you are a director and major shareholder (DGA), or if you work for your own private limited company (BV), we will treat you as self-employed.
If you have forgotten your password
If you forget your password or username, you must apply for a new account. You will have to choose a new username.
If you need an A1/certificate of coverage urgently
If your employee cannot start working because he or she does not yet have an A1/certificate of coverage
In most countries, inspectorates will accept a copy of the application for an A1/certificate of coverage. If an employee is denied access to a work site or a client will not pay an employee because he or she does not yet have an A1/certificate of coverage, contact us by telephone. We will then see whether your application can be processed with priority.
Will your employee be working in Australia, Egypt, Macedonia or New-Zealand?
If your employee will be working in one of the above countries, you must submit the application within 3 months of your employee's departure from the Netherlands.
Working in Belgium or Sweden temporarily
If your employee is going to work in Belgium temporarily, you have to report this to the Belgian authorities before the employment starts. You can do so using the "mandatory Limosa declaration" on the Limosa website.
Since 1 July 2013, Sweden has had a similar notification system. (This only applies for postings of 5 days or longer).
Employers based outside the Netherlands
Online applications are not possible for companies based outside the Netherlands. In this case, you can download an application form (PDF, 1.1 Mb) and send it in by post.
