As an ANBI, Stichting Improve 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.
