Important information regarding use of this online portal

You are responsible for the availability and performance of your own systems. Issues with these systems do not void your responsibility to submit your tax returns and/or information on time. Therefore do not wait with submitting information with the competent authority until the last moment.

The competent authority is responsible for their systems and optimum availability thereof. In the unlikely event of a persistent interruption of service which made it impossible to submit your tax return (on paper at the Tax Office) in a timely manner, an appropriate solution will be proposed for that specific situation.

If you no longer have your username, password or neither of these, you still need to submit your tax returns and/or information within the applicable deadlines. In these cases always contact the competent authority as soon as possible. If this leads to non-compliance with the deadlines, you risk consequences.

The tax returns or information is submitted when the information is actually received by the competent authority and/or it’s systems. If submitted correctly, you can find the date of submittal on the proof of receipt (document and e-mail) and in the online tax return case/file.

Make sure that the tax matters related responsibilities are well embedded and assigned within your company. Decide who should be able to log into the secure area that is the online portal. You will receive only one username and password. In case of FATCA information exchange this should be the Responsible Officer as registered with the IRS.

Is the portal secure?

Security is one of the most important aspects of online portals. Several security measures have been taken to ensure that the system is secured. Access is secured and guarantees the confidentiality of your data. The web pages for online reporting use the HTTPS protocol. This stands for HyperText Transfer Protocol Secure and can be recognized by the first letters of the web address. The data you send will be encrypted, making it impossible for outsiders to view these data.

Nonetheless, additional security measures are recommended at all times. The tax authorities have taken measures to secure the online portal and the transfer of data. You can also secure your own ICT environment by installing firewalls, virus scanners and anti-spyware applications.
