Limited tax advantages are awarded for a single donation with a minimum of 1%, or at least 60 euro, and a maximum of 10% of your taxable income. Let us say your taxable income on a yearly basis is 35.000 euro. This means you will only be able to get a percentual refund for your donations if you donate no less than 350 euro and no more than 3500 euro a year. Please visit this page from website of the Dutch Tax Authorities for more information.
