Filing tax returns via the old entrepreneurs’ portal

Because entrepreneurs not registered with the Netherlands Chamber of Commerce (KVK) could not apply for eHerkenning, they were able to continue to use the old portal. Since 29 January 2024, eHerkenning has also been available for companies and organisations without KVK number. That is why we will permanently close the old portal for entrepreneurs on 1 July 2024.

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. For some taxes, you do this online and for others offline. If you are filing a tax return offline, download the form, complete it, sign it and submit it.

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.
