Internal Revenue Service officials say groups who are required to file Form 990 and fail to do so are at risk of losing their tax exemption. Do not include Social Security numbers or other personally identifiable information on the form, as it can lead to identity theft. The IRS and most organizations are required by law to make most parts of their completed forms available to the public, including schedules and attachments.
Forms 990, 990-EZ and 990-PF are all marked “open to public inspection” in the top right hand corner of the first page. IRS officials say e-filing the forms lowers the risk of including unnecessary personal information.
