Make a regular tax-friendly donation for a minimum period of 5 years. You can arrange this directly with us, without the intervention of a notary. The periodic donation is fully deductible, which means that the tax authorities will soon be ‘paying back’ 42 or 52 percent of the donation. An example: you used to donate € 100 per year, if you increase this amount to € 200, you can, depending on the applicable income tax rate, receive back € 104 per year. So you donate more to Biblionef without paying more yourself!
