Portal Mandatory Disclosure / DAC6
Welcome to the DAC6 data portal of The Netherlands Tax and Customs Administration.
You can access the portal by logging in using eHerkenning (level 3 or higher) or your username and password.
If eHerkenning is not available to you and you do not have a username and password yet, use the registration form to register for an account.
If you are self-employed (ZZP'er) and encounter the following error while logging in using eHerkenning: 'Belastingdienst vereist gegevens van uw organisatie die niet bij ons zijn geregistreerd', please register for an account through the registration form. We are working on making login through eHerkenning on the DAC6 data portal possible in the future.
