IRA Charitable Rollovers

If you are a US taxpayer aged 70.5 or older and have an Individual Retirement Account (IRA), you are eligible to make a gift via an IRA Charitable Rollover, also known as a Qualified Charitable Distribution (QCD). In order to benefit from the tax advantages of satisfying all or some of your required minimum distribution through an IRA Charitable Rollover, the gift must be issued directly from your IRA custodian.

The Wikimedia Foundation directs all IRA gifts to the Wikimedia Endowment, where they are invested to ensure the long-term future of Wikipedia and other Wikimedia projects. For more information, contact legacy@wikimedia.org.


Charitable Gift Annuities

For US donors who are 55 or older, a charitable gift annuity (CGA) can provide you and/or your loved ones with an income for life or for a specific number of years. In addition to an immediate income tax deduction, you will enjoy the satisfaction of knowing your gift will help Wikimedia endure for generations to come. Gift annuities with Wikimedia are offered through the National Gift Annuity Foundation. Contact legacy@wikimedia.org to learn more.

Once realized, your gift will be added to the Wikimedia Endowment, where your legacy will live on by providing support to Wikimedia projects in perpetuity.

Legacy gifts are exempt from U.S. federal estate taxes. Make a legacy gift online at no cost using FreeWill (in the U.S.) or by including the following sample language in your will:
