When you form a group with a charitable purpose, you apply for 501(c)(3) status; if granted, your organization is exempt from tax, and it can attract tax-deductible gifts. However, the IRS will assume that your organization is a private foundation, as defined by 509(a), unless you can prove otherwise. In other words, your organization will be covered by both 501(c)(3) and 509(a). If you can prove that 509(a) doesn't cover you, your organization will be deemed a public charity. The advantage to proving that 509(a) doesn't apply is that donors will be able to make larger gifts without coming up against deductibility limits. In general, we say that gifts are tax-deductible, but actually there are limits on how much of your income you can deduct in any one year. Gifts to private foundations allow donors to deduct a smaller percentage of their income than gifts to public charities. The difference between a private foundation and a public charity -- and remember, both are 501(c)(3) -- is that a public charity can demonstrate that it receives the bulk of its funds from a variety of sources, whereas a private foundation receives most of its funding from limited private sources or a single source. So, for example, if your institution gets 95% of its funds from its endowment, it's a private foundation; but if it has a mix of earned income, gifts, public funding, and endowment, you can bet that it "escapes" 509(a) classification. With respect to lobbying, public charities are allowed to express their opinion because they are operating in the public interest, and so we assume that what they have to say will be an important to the public debate. So they are allowed to lobby with the understanding that they can't devote much effort to it. Private foundations, on the other hand, are under a ban. Clear as mud, no doubt.
