Unrelated Business Income Tax Returns, 2003:
Financial Highlights and Special Analyses of Exempt-Organization Reporting Quality (PDF)

Article by Margaret Riley, SOI

Nonprofit charitable and other types of tax-exempt organizations reported $8.4 billion of gross income from activities that were considered unrelated to their philanthropic missions for Tax Year 2003 (Filing Years 2004 and 2005). Engaging in these types of activities is permissible, but income produced from them is subject to Federal taxation and must be reported on Form 990-T, Exempt Organization Business Income Tax Return. The 36,064 Forms 990-T filed to report "unrelated business income" (UBI) for 2003 slightly exceeded the number filed for each of Tax Years 2001 and 2002, but remained below the number filed for any tax year between 1995 and 2000.
