More than 1,400 nonprofit organizations and charities in Idaho have lost their tax-exempt status after they failed to file annual reports with the IRS. The Post-Register reports that about 18 percent of the state's 8,000 nonprofits and charities have lost their status. Karen Connelly, an IRS spokeswoman for Idaho, says the organizations lost the designation automatically last month after failing to file annual reports for three consecutive years.  She says many of them are defunct organizations that didn't tell the agency they were closing.  But others on the list are still operating, such as the Idaho Falls Advertising Federation.  Federation president Lisa Fischbach says her organization has re-filed its paperwork with the IRS and it has retained its status as a tax-exempt agency.
