An IRS investigation is typically signaled by official correspondence (audit letters), direct contact from a Special Agent, or third parties (banks/accountants) reporting inquiries about your finances. Key indicators include unannounced visits, frozen assets, receiving a summons for records, or an auditor suddenly going silent, which may signal a shift from civil to criminal review.
