Yes - De Vierklaver is on the FOD Financiën (SPF Finances) official list of approved tax-deductible institutions under article 145³³ CIR/WIB. As a Belgian taxpayer, you can claim a 45% tax reduction on annual donations of at least 40 euros to this organisation. The organisation must issue a fiscal certificate (fiscale attest / attestation fiscale) for donations of 40 euros or more - keep it for your tax return. The ministerial recognition is re-published yearly and GiveRadar synchronises against the official PDF weekly.
De Vierklaver is a Belgian non-profit association (VZW in Dutch / ASBL in French) - the country's standard legal form for civic, cultural, charitable and sports associations. A VZW/ASBL is a separate legal entity governed by a general assembly and a board of directors, regulated by the Code of Companies and Associations (CSA / WVV). VZW/ASBL is the dominant legal form for Belgian charities, civic associations, cultural and sports groups: there are roughly 145,000 of them on file at the Crossroads Bank for Enterprises (KBO). It is registered with the Crossroads Bank for Enterprises (Kruispuntbank van Ondernemingen / Banque-Carrefour des Entreprises), with KBO number 0436.015.889.
You can verify De Vierklaver's legal status in three ways. First, look up the KBO record directly: https://kbopub.economie.fgov.be/kbopub/zoeknummerform.html and enter 0436.015.889 (or 0436015889). The result page shows the official name, legal form, address, status, and registration date. Second, look up the most recent annual accounts at the National Bank of Belgium Central Balance Sheet Office (https://consult.cbso.nbb.be/consult-enterprise) using the same KBO number - Belgian non-profits above the small-association threshold (around €312,000 in revenue, or any with paid staff) are legally required to file there each year. Third, every legal-form change, board appointment, statute amendment, dissolution and registration appears as a public notice in the Moniteur belge / Belgisch Staatsblad (https://www.ejustice.just.fgov.be) - searchable by KBO number. If those three sources agree on name, address and current legal form, the organisation is legitimate.
You can donate to De Vierklaver directly through its donation page (https://de-vierklaver.be/home/over-ons/steun-ons/). Belgian charities typically accept domestic transfers via Bancontact, SEPA bank transfer, and online payment processors (Mollie, Stripe). A large share of larger Belgian charities channel donations through the King Baudouin Foundation (KBS-FRB / kbs-frb.be), which administers project funds and issues the fiscal certificate on behalf of the recipient charity. International donors can give by SEPA transfer (Belgium is in the eurozone, so intra-EU transfers are inexpensive), PayPal, or fundraising platforms common in Belgium such as iRaiser, HelloAsso, Donorbox, and GoFundMe. Always confirm the recipient's IBAN and KBO/enterprise number before sending funds, and ask the organisation to send the fiscal certificate (fiscale attest / attestation fiscale) for donations of 40 euros or more if you intend to claim the 45% tax reduction.
