In America
every non-profit organization must make its tax files public.
There's a from, the IRS From 990, that they have to make available to show where their money goes. I'd make it a rule that before my radio, TV or website promoted a charity, I'd examine the IRS From 990 first.
Every charity, including those that are well known and highly thought of, such as Make-A-Wish Foundation.
should undergo the same examination. After you have looked the form over, give the charity a call and check your data. Clerical errors do seep through. The IRS Form 990 will include a phone number on the front page. Usually all of these charities have these forms from the previous year available on their websites.
