At times, at least in the media, there appears to be a love/hate relationship between "some" nonprofits and the IRS. Well, the IRS has the aim to improve it's side of the equation with newly proposed regulations that will help clarify the eligibility of the ever controversial social welfare organizations for 501(c)4 status.

Meanwhile, nonprofit staff and possibly their boards might be interested in being regularly updates with what's going-on at the IRS regarding nonprofits. There's a no-cost e-newsletter to subscribe to at this address. And, for all the basics about being nonprofit, try this link.
I would proposed that the IRS does go out of its way to support citizen's desire to pursue nonprofit interests. Information is a great starting point.
