Compliance Checks: A compliance check may include review of the following items: Whether an organization is adhering to recordkeeping and information reporting requirements Whether an organization's activities are consistent with its stated tax-exempt purpose A compliance check is a review of information and forms that IRS requires organizations to file or maintain - for example, Forms 990, 990-T, 940, 941, W-2, 1099, or W-4. The check is a tool to help educate organizations about their reporting requirements and to increase voluntary compliance. See Publication 4386 PDF, Compliance Checks--Examination, Audit or Compliance Check? Please note: A compliance check is not an examination/audit; it does not directly relate to determining a tax liability for any particular period. Compliance Check Questionnaires: Compliance check questionnaires are a variation of compliance checks. The IRS mails compliance check questionnaires (or letters directing recipients how to complete the questionnaires on-line) to particular types of tax-exempt organizations to learn more about these types of organizations. When the IRS receives responses, it generally reviews them to determine whether and how those organizations are complying with applicable tax-exempt law and then decides what, if any, further action is appropriate to be taken.
