Fake HMRC Calls in 2026: What They Sound Like Now

Naomi Patel 3 min read

If you live in the UK and you’ve answered an unknown call this year, there’s a fair chance it was an HMRC scammer. The “tax arrest” call has been the single most-reported scam on GhostCallers for three of the last five years. What’s changed in 2026 is the quality — and that has implications for the people most likely to be caught out.

The classic script (still in circulation)

The original version, which most readers will recognise, is a robotic voice:

“This is HMRC. There is a warrant for your arrest in connection with a tax fraud. Press one to speak to your case officer, or stay on the line.”

If you stayed on the line — or pressed 1 — you’d be transferred to a person with a script. They’d demand payment in gift vouchers or bank transfer to a “safe account”, and they’d threaten arrest, deportation or a court summons if you put down the phone.

The reason this scam works isn’t because the script is convincing. It works because of urgency and surprise. People aren’t expecting it, and they panic.

What’s changed in 2026

Two things have changed materially:

The voices are better. Modern AI text-to-speech is essentially indistinguishable from a real call-centre operator. Scammers can now generate calm, slightly weary, vaguely Mancunian voices that sound like real civil servants. The “press one to speak to a case officer” prompt is gone — they want to keep you on the line.

They use texts as priming. A growing number of reports describe a text arriving before the call. It might say “HMRC: notice 2025/19 will be sent to your registered address” — innocuous, but enough to make the follow-up call seem credible.

How HMRC actually contacts you

HMRC will:

  • Write to you by post.
  • Send a generic text message (never asking for personal details).
  • Email you with a clear “do not reply” address from a verified gov.uk domain.

HMRC will never:

  • Phone you and demand immediate payment.
  • Threaten arrest or deportation over the phone.
  • Ask you to pay in vouchers, cryptocurrency, or by bank transfer to a personal account.
  • Ask you to confirm your full National Insurance number.

If you’re unsure whether a contact from “HMRC” is real, hang up and call HMRC back on 0300 200 3300 (the public helpline, listed at gov.uk).

What to do if you’ve received the call

  1. Hang up. You don’t need to be polite, and you don’t need to threaten them. Just put the phone down.
  2. Don’t return the number from a missed-call list, even out of curiosity.
  3. Forward any related text message to 7726 — it’s free and the message goes straight to the National Cyber Security Centre.
  4. Add the number to GhostCallers. Even short reports help — “robotic HMRC voice, hung up” is enough.
  5. If you parted with money, call your bank using the number on the back of your card, then report to Action Fraud at 0300 123 2040.

And if it caught a relative?

The most common pattern we see is an adult child contacting us after a parent or grandparent has been targeted. The single most effective thing you can do is have the conversation in advance — before they get the call. Tell them, in plain language, that HMRC will never phone them. Tell them they can always hang up on anyone claiming to be HMRC, and that they should never feel impolite for doing so.

It’s a small conversation. It’s also the cheapest fraud-prevention tool any family has.
