Donations to charities that are public in nature can be tax-deductible to the extent of 60 percent of the
donor's earnings. The corporate limits are generally 10 percent. Public charities also have to have a
governing board comprised of non-related, independent people.Private foundations are usually
regarded as non-profit entities that aid public charities through grants, but that's not the case in all

as 30 percent their income. The management of private foundations could be more closely controlled

foundation. These foundations usually run programs that are similar to those of foundations that are
