The Internal Revenue Service has developed an online database of 400,000 nonprofits that have lost their tax-exempt status for failing to file tax returns.Previously, the IRS released information about groups that had lost their tax-exempt status only by state, which made it difficult to find groups by other criteria. The new Exempt Organizations Select Check is updated monthly and is on the same Web page as the agency’s main database of all nonprofits that can accept tax-deductible donations.
