NEW IN 2024

May 2024

A new regulation concerning tax certificates was passed at the end of 2023. Associations must henceforth provide the National register Number (NN) of all donors who want and are entitled to a tax certificate to the tax authorities*. (PFS Finance Obligation –Article 323/3 CIR92).

The government is thereby intent on ascertaining the identity of donors so as to guarantee that tax benefits are applied in a transparent and correct manner. This data item has thus become mandatory for issuing tax certificates.

The same rules apply for legal entities and companies concerning tax deductions for donations made as of January 2024. The company number (Crossroads Bank for Enterprises [central business register]) must be provided instead of the NN.

Please note that:

Tax certificates for couples are preferably issued to one and in the name of one of the partners, with his or her NN (the deductible amount will be included automatically in the joint tax return).
Most foreign nationals who reside and pay taxes in Belgium have a valid BIS NN [a Social Security Identification Number] for tax form 281.71. Donors concerned can find their BIS number on their Belgian identity card, payslips, tax assessment notice, pension file, etc.

If no donor personal data are known or if a donor wishes to remain anonymous, the tax certificate cannot be issued...

We understand that confidentiality is important, and you can rest assured that your data will be processed securely in accordance with data protection legislation currently in force.

If you are affected, you are kindly requested to send us your NN (indicating your full surname, forename, and postal address) to the following address: This email address is being protected from spambots. You need JavaScript enabled to view it. or via the online hereunder :

Thank you in advance for your cooperation.
