Scammers pretending to be from the HMRC threaten potential victims with lawsuits, with warrants for their arrest or demands for outstanding tax to be paid.

Which? has obtained two recordings of the automated scam phone calls. Watch the video so you know what they sound like so you don’t get caught out.

HMRC phone scam: warrant for arrest

In one of the scam telephone messages, an automated male voice warns there’s a warrant for your arrest because there’s a legal case to be filed in your name.

It says because you’ve now been notified, you then have to call the HMRC on a number provided.

The voice signs off with: ‘Don’t ignore.’

HMRC phone scam: officer Sarah Wilson

The other scam voicemail is an automated female voice purporting to be Officer Sarah Wilson from HM Revenue & Customs.

She urges you or your solicitor to call her back on a provided number. The message threatens that if you or your solicitor doesn’t call them back, ‘then get ready to face the legal consequences’.

This is another tactic to make you act quickly – this time to pressure you into responding out of fear of severe consequences.

Threatening language

Both the scam calls are threatening and pressure you into acting quickly - this is a common sign of a scam as it’s designed to stop you from thinking through your actions.

Being contacted out of the blue

Often being contacted out of the blue is a sign something could be a scam - but sometimes legitimate companies will need to do this.

So it’s always a good idea to try verify the identity of the caller. You can do this by getting them to answer questions only the company would know - like your tax reference number.

If you feel uncomfortable or you’re sure it’s a scam, hang up.

Asked to share personal details

If you’re asked to share personal details over the phone and you couldn’t verify their identity, hang up.

You should then research the organisation’s number independently.

You can do this by looking up the HMRC’s call centre numbers on or by using the number on a trusted piece of correspondence – such as a letter you’ve been sent.

Call them back on that number.
