Stichting het Sikkelcelfonds is registered in the Netherlands. Stichting het Sikkelcelfonds has ANBI (Algemeen Nut Beogende Instelling) status, so donations are tax-deductible. You can deduct gifts that exceed 1% of your threshold income (minimum 60 euros). Periodic gifts (committed for 5+ years) are fully deductible without threshold.

Stichting het Sikkelcelfonds is a Dutch foundation (stichting) - the most common legal form for charities and public-benefit organisations in the Netherlands. A stichting has no members, is governed by a board, and is established by notarial deed for a specific purpose. It is the only Dutch legal form that can hold ANBI (public-benefit) status without member oversight. There are about 250,000 stichtingen on file at the Dutch Chamber of Commerce (KvK), of which roughly 50,000 hold ANBI status with the Belastingdienst. It is registered with the Kamer van Koophandel (KvK), the Dutch Chamber of Commerce, with RSIN 857747873.

You can verify Stichting het Sikkelcelfonds's legal status in three ways. First, look up the RSIN directly on the Belastingdienst ANBI register: https://www.belastingdienst.nl/wps/wcm/connect/nl/aftrek-en-kortingen/content/anbi-status-controleren and enter 857747873. The result page confirms whether the organisation currently holds ANBI status - a prerequisite for tax-deductible donations in the Netherlands. Second, search the Kamer van Koophandel public registry at https://www.kvk.nl/zoeken/ - the KvK record shows the legal form (Stichting / Vereniging / Coöperatie), registered address, board composition (where disclosed), and the date of incorporation. Third, every ANBI is legally required by the publicatieplicht to publish on its own website: the policy plan, financial statements, an overview of activities, board composition, and remuneration policy. A working ANBI page with current financials is the strongest signal of legitimacy beyond the registry. If all three sources agree on name, address and ANBI status, the organisation is legitimate.

You can donate to Stichting het Sikkelcelfonds directly through its donation page (http://www.hetsikkelcelfonds.nl/doneren). Dutch charities typically accept iDEAL (the standard Dutch online-banking payment method), Tikkie payment requests, Bancontact for cross-border donors, SEPA bank transfer to the organisation's IBAN (account numbers starting with NL), and online payment processors (Mollie, Stripe). Many larger Dutch charities use platforms like Geef.nl, GeefSamen, Kentaa, and Pifworld for online fundraising. International donors can give via SEPA (the Netherlands is in the eurozone, so intra-EU transfers are cheap), PayPal, or GlobalGiving. For donations to count as a 'periodieke gift' - fully tax-deductible without a threshold - a written agreement (overeenkomst periodieke gift) committing for at least five years is required. Always confirm the recipient's RSIN and ANBI status before sending funds intended for the tax deduction.

Stichting het Sikkelcelfonds carries the CBF-Erkend Goed Doel label - the Dutch quality seal awarded by the Centraal Bureau Fondsenwerving (CBF). To qualify, a charity passes a three-yearly independent audit covering governance (separation of board, oversight, and management), financial transparency (audited annual accounts, clear expense breakdown), effective use of donations, responsible fundraising practices, and a working complaints procedure. You can read the public 'CBF-paspoort' for Stichting het Sikkelcelfonds here: https://cbf.nl/organisaties/7438. The passport shows the most recent audit outcome and the headline financial ratios.

As an ANBI, Stichting het Sikkelcelfonds is legally required to publish the following information on its own website, free of charge and without a login (the 'publicatieplicht' obligation under Uitvoeringsregeling AWR 1994 art. 1a): the policy plan, an overview of the past year's activities, the financial statements (balance sheet, profit-and-loss, explanatory notes), board composition with names, and the remuneration policy for directors and key staff. Larger ANBIs (turnover above €50,000) must also publish a fuller financial report using the Belastingdienst's standard ANBI publication form. If you cannot find these documents on the organisation's website, that is a red flag worth raising with the board before donating.
