Donatio Tax
Generate tax certificates for donations received by your nonprofit.
What Is Donatio Tax?
When a person makes a donation of at least 40 EUR to an approved nonprofit (ASBL), they can benefit from a 45% tax reduction on the amount donated. To claim this, the ASBL must provide them with a tax certificate (an official certificate). Donatio Tax helps you manage these donations and automatically generate compliant certificates.
Legal basis — Article 145/33 of the Income Tax Code (CIR 1992). The 45% tax reduction applies to donations of at least 40 EUR per calendar year made to approved institutions. The ASBL must be approved by the Federal Public Service Finance (SPF Finances) to issue certificates.

Record a Donation
- From Donatio Tax, click New Donation.
- Fill in:
- Donor name
- NISS (national register number) of the donor (required) — the Belgian national number, 11 digits, found on the back of the identity card. It is necessary for the certificate to be valid for tax purposes.
- Amount of the donation (minimum 40 EUR for tax deductibility)
- Date of the donation
- Payment method (bank transfer, cash, etc.)
- The donation is recorded and associated with the organization.
NISS Validation
The NISS (national register number, also known as Rijksregisternummer in Dutch) is automatically validated by the system:
- Format: 11 digits (XX.XX.XX-XXX.XX)
- Modulo 97 check: a mathematical calculation that verifies the number is correct (no typos)
- Compatibility: works with numbers of persons born before and after 2000
NISS required — Without a valid NISS from the donor, the tax certificate will not be accepted by the tax authorities. Always verify the number with the donor.
Generate a Certificate
- Select one or more donations.
- Click Generate Certificate.
- The PDF is created with all required legal mentions (name, NISS, amount, date, ASBL approval number).
- Download and send it to the donor before the tax filing deadline.
