Gifts of Appreciated Securities

Gifts of appreciated stock are a popular alternative to cash gifts since they can offer significant tax advantages. Donors residing in the U.S., for example, may receive an income tax deduction up to the full market value of the securities and can also avoid capital gains tax on the appreciation. In essence, you save twice—on income tax and capital gains tax. If you have any questions about the tax implications of a stock gift to AAAS, be sure to consult your tax advisor.

How to Make a Gift of Securities to AAAS

If your broker or bank holds your certificates of stock:

Inform your broker that you wish to make a gift of stock to AAAS. The broker will want to know the name of the stock and number of shares you are contributing.

After notifying your broker of your desire to transfer stock to AAAS, please contact the Office of Philanthropy and Strategic Partnerships and let us know:

  • Your broker's name and telephone number,
  • the name of the stock and number of shares you wish to contribute,
  • the date of the planned transfer, and
  • what program you would like your gift to support.

We will provide transfer instructions directly to your broker. A gift receipt will be sent to you reflecting the average value of the stock on the date of transfer.

Please remember, DO NOT sell the stock! This could jeopardize your ability to receive the full tax benefit of your gift.

If you hold the certificates of stock yourself:

Contact Rita Elmore at or by phone at (202) 326-7025 for AAAS's stock transfer information or for more details on how to make the transfer.
