A charitable organization is a type of non-profit organization (NPO). It differs from other types of NPOs in that it centers on philanthropic goals as well as social well-being (e.g. charitable, educational, religious, or other activities serving the public interest or common good).

If you exclude Gavi, then the list is dominated by major health charities, such as Research UK and MacMillan; global development groups Save the Children, Oxfam and the British Red Cross; and animal charities such as the RSPCA and the RSPB. Humans, birds and animals gather together in the top 10.

You may deduct charitable contributions of money or property made to qualified organizations if you itemize your deductions. Generally, you may deduct up to 50 percent of your adjusted gross income, but 20 percent and 30 percent limitations apply in some cases.
