Excerpt:
Donations to the Council on American-Islamic Relations (CAIR) no longer are tax deductible after the organization was among 275,000 tax-exempt organizations purged earlier this month by the Internal Revenue Service.
The groups failed to file required annual reports, known as form 990s, detailing their revenues and expenses, for three consecutive years. CAIR had been a non-profit on its own, but in 2007, the IRS approved a separate tax-exempt CAIR Foundation. The foundation never filed any subsequent reports. Both the foundation and CAIR national are on the purge list.
CAIR has 30 state chapters throughout the country, many of which have their own non-profit designations which remain active.
