The IRS (www.irs.gov) notifies taxpayers of an audit exclusively through mail, never by phone, email, or social media. You will receive a letter—such as Letter 566 or 566D—outlining the issues, required documents, and a deadline to respond. Check your online IRS account (https://www.irs.gov/payments/online-account-for-individuals-frequently-asked-questions) for official notices.

Key indicators are official IRS letters, contact from CI special agents, third-party inquiries, and formal summonses for records, signaling serious scrutiny beyond a simple audit.
