The Effective Altruism Foundation helps Swiss taxpayers to get tax deductibility for donations to effective charities within a wide range of cause areas (many of which are recommended by Giving What We Can).
The money that can be claimed from a tax-deductible donation may enable you to be more generous than you initially thought.
We recommend that Giving What We Can members who are Swiss taxpayers donate via the Effective Altruism Foundation report their donations on their Pledge Dashboard so that they can claim a tax-deduction and still track their pledge fulfilment.
