Is that IRS or tax-office voicemail a scam?

Last reviewed 17 May 2026 · Published by Is This A Scam? (a FortifiedWall service)

If you got a voicemail or robocall claiming to be the IRS — demanding you verify your tax filing, settle a debt, or call back urgently — it is a scam. The real IRS does not cold-call people to threaten them. Here is how to tell, and what to do instead.

What it looks like

A recorded or live voicemail from an unknown number. A caller, often using an official-sounding but fabricated name, says they are from a tax office, a “tax filing mediation” unit, or the IRS. They tell you your filing is under review or your account has a problem, and you must call back “today” — usually at a number different from the one that called you.

If you call back, the script escalates: a supposed debt, a threat of arrest or a frozen account, and a demand for payment by gift card, wire transfer, or cryptocurrency.

Why it works

It pairs authority with fear. Most people do not know exactly how the IRS contacts them, so a confident official voice plus a deadline is enough to start a panic. Once you are afraid, the scammer controls the pace and pushes you to pay before you can check anything.

Red flags to watch for

  • An unsolicited call or voicemail — the IRS first contacts you by physical mail.
  • The callback number is different from the number that called you.
  • Threats of arrest, deportation, lawsuits, or a frozen account.
  • Pressure to act “today” or “before the review closes.”
  • Any demand to pay with gift cards, wire transfer, or cryptocurrency. No real agency does this.

What to do

  1. Do not call back — not the number on caller ID, and not the callback number left in the message.
  2. Do not give any personal or payment information.
  3. Block both numbers and report the call to the FTC at reportfraud.ftc.gov.
  4. If you have a genuine tax question, contact the IRS yourself through irs.gov, using only the contact options published there.
  5. Not sure? Email a screenshot of the voicemail transcript, or the recording, to [email protected] for a verdict.

A real example

Verdict: SCAM

A user sent a screenshot of a voicemail. The caller used a fabricated name, claimed to represent a “tax filing mediation” office, asked the recipient to verify their filing status under time pressure, and left a callback number that differed from the line that had actually called.

No such office exists. The IRS handles US tax matters and does not cold-call people about account reviews. A callback number that differs from the calling number is a classic tactic to route victims to a scam call center. The urgency — “before the review cycle concludes,” “call back today” — was designed to force a decision before verification. Calling back would have led to a demand for gift cards, a wire transfer, or cryptocurrency.
