User name and password (entrepreneurs)
All entrepreneurs will have received a user name and password. These grant you access to the secured section of the Tax and Customs Administration's Internet site. You can surf to the site to view the status of your tax returns and/or statements and file digital tax returns. You also receive login data when you file tax returns using tax return or administrative software or via a tax service provider.
You will have received a letter with your user name and a letter with your password for each of your BSN/RSIN/sofi numbers. You use these to log in to the secured section of the Tax and Customs Administration's Internet site.
Have you mislaid your user name and password?
If you have not logged in before and you have mislaid your user name, password or both then contact the Tax Information Line.
If you have logged in earlier and you have mislaid your user name, password or both then you can submit a new application for them via Inloggen voor ondernemers (Entrepreneur login window - only available in Dutch), provided that you have previously stated an e-mail address for this purpose. The Tax and Customs Administration will then send an e-mail with your password or user name to you within 24 hours. When you have forgotten both then you will receive a new password and a new user name in 2 separate e-mails.
When you have not stated an e-mail address then you will need to call the Tax Information Line. The Tax and Customs Administration will then send you your login data by post within 10 working days.
Consequently, you will have to wait longer before you receive your login data.
This can cause problems when the last date for filing a tax return is drawing near.
Is your account blocked?
If so, call the the Tax Information Line. You will receive new login data by post within 10 working days. This will give you access again to the secured section, containing your overview of declarations and returns.
