Refer to these Schwab Charitable guidelines to help ensure your contributions are received and processed by December 31 (the IRS deadline for inclusion in your year-end tax return).
*The type of securities and how quickly the securities are transferred by the financial institution currently holding the investments may impact Schwab Charitable’s ability to receive contributions by year end.
† December 31, 2016, occurs on a Saturday. Although U.S. post offices are typically open on Saturdays, hours may be restricted. Please plan accordingly.
