Filing tax returns via the old entrepreneurs’ portal
If it is not possible for you to log in to Mijn Belastingdienst Zakelijk (new business portal), then you may continue to use the old entrepreneurs’ portal. This portal will cease to exist when it is possible for all entrepreneurs to use Mijn Belastingdienst Zakelijk.
On 'Inloggen voor ondernemers' (only available in Dutch) you can read which tax matters you can currently manage in Mijn Belastingdienst Zakelijk, and which you can still manage in the old portal.

When you are logged in
When you are logged in to Mijn Belastingdienst Zakelijk, you will find an overview of your tax returns. It shows which returns you still need to file or have already filed. Subsequently, you can file your tax return. Depending on the tax, you do so online or offline. In the latter case, you download the form, fill it in and send it in properly signed.
Please note!
For security reasons, the portal will be locked automatically if you have not entered any data for more than 30 minutes. You will then have to log in once again.
Signing your tax return
If you file your tax return online, you sign your tax return using your user name and password.
If you file a tax return offline, you will sign your tax return by hand.
Return messages
When you file a digital tax return via the old entrepreneurs’ portal or manage other tax matters in this portal, you will receive a return message from us.
