Yes. If you have a specific charity on the TCA's list of grantees, you may specify your donation of cash or stallion seasons be earmarked for that charity, or charities, and they will receive the proceeds, less 20% for "all other TCA Grantees". This ensures against a small group of popular non-profits gaining control of 100% of the available money for grants.
According to the most recent TCA IRS Form 990, posted on this website, over 96 cents of every dollar raised is donated directly to the annually accredited charities.
If the charity you are thinking of is not on the TCA list of grantees, that organization, as long as it has a 501 (c) 3 non-profit status and fulfills the TCA Mission found on the Home Page, may submit an application for a grant which will be reviewed by the TCA Board of Directors.
Another designation option is "Sector Designations". TCA's Mission on the Home Page outlines the Five sectors of charities we grant to and by designating your sector preference, you can be assured your donation dollars will be directed toward your specific affinity.
