Title 26 › Subtitle F — Procedure and Administration › CHAPTER 78 — DISCOVERY OF LIABILITY AND ENFORCEMENT OF TITLE › Subchapter A — Examination and Inspection › § 7602
The IRS can examine books, papers, records, and other data. It can summon people who are liable for tax, their officers or employees, or anyone who holds their records to bring those items and give sworn testimony. The IRS can do this to check a return, make a return if none was filed, figure out who owes tax (including transferees or fiduciaries), collect taxes, or investigate offenses tied to tax laws. The IRS must have a reasonable indication before using financial‑status or economic‑reality methods to look for unreported income. The IRS must tell a taxpayer before it contacts other people about that taxpayer’s tax liability. The notice must name a contact period of no more than 1 year and generally be given at least 45 days before the period starts. The IRS will give a record of whom it contacted during that period, and will provide it on request. Exceptions apply if the taxpayer agreed, if notice would jeopardize collection or cause reprisal, or if a criminal investigation is pending. If the Justice Department has been asked to investigate or prosecute a person, the IRS may not issue or try to enforce a summons for that person while that referral is in effect; the referral ends when the Attorney General says prosecution won’t happen, a grand jury action is stopped, there is a final court outcome, or a related disclosure request is resolved. The IRS may only share records obtained here with outside experts who are helping the IRS, and only IRS staff or the Office of Chief Counsel may question witnesses under oath on the IRS’s behalf.
