Issues associated with making large donations via credit card

When donating via credit card, you will be charged standard credit card processing fees. This means that when a donor gives $10,000 by credit card, GiveWell receives about $9,785 (about $9,680 if using AMEX). In addition, your credit card company may flag the transaction and block it from going through. Generally, a call to the credit card company can resolve a blocked transaction.

Donors can avoid these issues by:

  • Mailing a check to GiveWell. GiveWell takes no fees when collecting donations. If you are interested in making a donation to GiveWell via check, please report your donation here. You can mail us a check at:

    1714 Franklin Street #100335

  • Donating via bank transfer to GiveWell. GiveWell takes no fees when collecting donations. If you are interested in making a donation to GiveWell via bank transfer, please follow the instructions here.

  • Give to top charities directly using one of the above methods. For many, but not all, of our top charities, you may donate via check or bank transfer or give securities directly to the charity. Please see considerations for each charity here. If you take this option, please use our donation report form to let us know about your gift; doing so helps GiveWell track our impact.

Donor requests to grant donations to our recommended charities are subject to our approval (more details on this here).

Other issues for larger donors to consider

Consider your tax rate

If you believe, for example, that your tax rate is likely to be higher next year than this year, you may wish to give at the very beginning of next year rather than the very end of this year. In addition to your marginal tax rate, you may want to consider whether you expect any tax policy changes that could affect charitable deductions, such as caps on how much you can deduct and, for U.S. taxpayers, the amount of the standard deduction.

As we have in the past, we will count donations made through January 31 towards our previous year's money moved.

Donor-advised funds

Donor-advised funds allow donors to make a charitable donation (and get a tax deduction) now, while deciding which charity to support later. The donation goes into a fund that is "advised" by the donor, and the donor may later recommend a grant from the fund to the charity of his/her choice.

Many large investment companies—Vanguard, Fidelity, Schwab—offer donor-advised funds.

Donor-advised funds charge fees on the assets held in the fund. These fees vary based on the amount of assets held and the investment option chosen by the donor. (For example, see Vanguard's page on fees.)

If you already have a donor-advised fund, you can follow the instructions here for making a gift to GiveWell in this way. If you'd like to set up a donor-advised fund, more information is available here.

GiveWell has a fund at Vanguard that donors can use if they do not wish to set up a fund on their own. (See this page for more information about contributing to this fund.)

Tax advantages of giving appreciated securities

Donating appreciated securities offers donors additional tax benefits. (For more information, see Fidelity's write-up on this topic.)

GiveWell maintains a brokerage account to allow us to accept donations of securities. If you are interested in making a donation of securities to GiveWell, please follow the instructions here.

Donor-advised funds may also be helpful in assisting donors in donating securities.
