Common questions

Why does GiveWell collect donations on behalf of its recommended charities? For two main reasons: (1) It allows us to track our own impact on donations and (2) it gives us a chance to ask you if you'd like to receive updates on GiveWell's research.

Does GiveWell charge fees on donations to its recommended charities? No, GiveWell collects no fees from donations to its recommended charities. 100% of your donation (after credit charge fees) will be used to support the charity or charities of your choice.

Will my donation be tax-deductible? GiveWell (a.k.a. The Clear Fund) is a federally-recognized tax-exempt 501(c)(3) organization. We are able to make grants for the support of our recommended charities, and U.S. donors are able to take tax deductions for donations to GiveWell to the extent permitted by US tax laws.
