The IRS notifies you of an audit only by mail, never by phone or email, sending a letter detailing the tax year, reason for examination, required documents, and instructions for mail or in-person review (office or field audit). This official letter will come via U.S. Postal Service, often requiring a signature, and provides contact info for the assigned agent. Always check that the notice includes an agent's name, phone number, and IRS ID, and be wary of scams demanding immediate payment, as the IRS won't threaten arrest or demand gift cards.
