While almost all nonprofits have Web sites, few are using the reach of the Internet to adequately disclose information about their organizations, according to a new report from GuideStar mentioned in Philanthropy Journal.

According to “The State of Nonprofit Transparency, 2008: Voluntary Disclosure Practices,” more than nine in 10 nonprofits have a Web site, and almost half post their annual reports, but only 13 percent post their audited financial statements and only three percent post their IRS letters of determination, both of which GuideStar recommends making available online.

In addition, nonprofits should keep their Web sites current, include brief biographies for staff and board members and post annual reports. JVA Consulting always counsels clients to be as transparent as possible.
