Internationale Gustav Mahler Gesellschaft is a international organization based in 1040 VIENNA, Netherlands. Registration: 828246142. Internationale Gustav Mahler Gesellschaft is classified as an international organization registered in Netherlands. The organization was founded in 1920.
Internationale Gustav Mahler Gesellschaft is registered in the Netherlands. Internationale Gustav Mahler Gesellschaft 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.
You can verify Internationale Gustav Mahler Gesellschaft'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 828246142. 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.
Contact Internationale Gustav Mahler Gesellschaft directly for current donation methods. 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.
As an ANBI, Internationale Gustav Mahler Gesellschaft 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.
