Break for fundraising organisations: tolerance period national number extended

Break for fundraising organisations: tolerance period national number extended

Latest update: this article was supplemented with recent state of play based on the webinar "Government action and fundraising" by the non-profit organisation Ethical Fundraising and Fundraisers Belgium on 12 September 2025.

Good news for the fundraising sector!

The government has decided to extend the tolerance period for collecting the national register number (NN, national number) for tax certificates. Thanks to the joint efforts of the industry as well as the Impact Coalition comes some extra breathing space now to adjust your operation to the new obligations.

What does this mean concretely for your organisation?

In April 2025, FPS Finance officially confirmed that the donation tolerance period will be extended until the end of 2025 (with submission via Belcotax in 2026). This means that the absence of the national register number is not a reason to block a chit: Belcotax will only issue a warning in this case. Only when a manifestly wrong rijksregisternummer is submitted, Belcotax will actually block the submission.

Donors retain their right to tax relief even if their NN is missing. In this case, the amount is not automatically pre-filled on their tax return and they have to add it themselves based on the tax certificate.

What is best to do now?

While this extension is welcome, we recommend not to fall silent. Keep up the active work of collecting the national register numbers of your donors. The extra time will give you a chance to do so in a thoughtful and careful manner.

So continue your ongoing actions, keep communicating with your donors, and build a future-proof administration step by step.

Why is the tolerance period good news?

This decision means less pressure and more time to optimise your internal processes. So you can work towards correct and complete registration of donor data in a calm, professional manner. And ultimately, this will ensure efficient handling of your tax certificates, with less stress and more confidence with your team and your donors.
