Tax inquiries and examinations of churches Congress has imposed special limitations, found in section 7611 of the Internal Revenue Code PDF, on how and when the IRS may conduct civil tax inquiries and examinations of churches. The IRS may begin a church tax inquiry only if an appropriate high-level Treasury official reasonably believes, on the basis of facts and circumstances recorded in writing, that an organization claiming to be a church or convention or association of churches may not qualify for exemption, may be carrying on an unrelated trade or business (within the meaning of IRC § 513), may otherwise be engaged in taxable activities or may have entered into an IRC § 4958 excess benefit transaction with a disqualified person.
