If the IRS flags your tax return, you'll likely receive a notice (like a CP05 or Identity Theft letter) delaying refunds, asking for verification of income, credits (like EITC/CTC), dependents, or your identity, and you must respond with documentation to resolve it, or risk denied refunds or audits, with serious penalties possible for intentional evasion, not simple mistakes.

What happens if you get flagged by the IRS?

The IRS will attempt to verify whatever information triggered the review. In the meantime, you won't be issued a refund if you're expecting one. If you owe taxes, you will still need to pay by the tax filing deadline to avoid a penalty.

How do you know if the IRS is investigating you?

You know the IRS might be investigating you through official mail (first contact), phone calls (often with automated messages to IRS.gov), or in-person visits, but signs of a criminal probe include contact with IRS Criminal Investigation (CI) agents, subpoenas to you or your bank, questions to your accountant/bank, unusual account activity (freezing/refusing transactions), or agents suddenly going silent after an audit. 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.
