Fraudsters are targeting unsuspecting people with fake demands and attempts to pressure them into sharing their personal details.

So HMRC is reminding anyone who needs to file their self-assessment before the 31 January deadline to be vigilant.

What tactics are scammers using?

Fraudsters often contact people via:

  • email
    text message
    phone call

Their messages may claim you owe tax, are due a refund, or face penalties - all designed to make you panic and act without thinking.

What red flags should I watch out for?

There are many signs that a phone call, email or text message might not be what they seem.

For instance, it could be a scam if it:

  • rushes you
  • is threatening
  • is unexpected
  • asks for personal information like bank details
  • tells you to transfer money
  • offers a refund, tax rebate or grant

But HMRC has stressed that it will never:

  • leave voicemails threatening legal action or arrest
  • ask for personal of financial information via text or email
  • contact you via email, text or phone to let you know about a refund or ask you to claim one

What can I do to protect myself?

To reduce your chances of falling victim to a scam, the HMRC recommends:

  • using strong, unique passwords for your accounts
  • stopping and thinking before giving away personal information or money
  • not responding to unexpected calls, texts or emails
  • not clicking on links or downloading attachments from unknown sources
  • not blindly trusting the caller ID, as this can be spoofed

How can I report a potential scam?

If you believe you’ve been contacted by fraudsters:

  • forward emails to [email protected]
  • report tax scam phone calls to HMRC on GOV.UK
  • forward suspicious text messages to 60599 

Full HMRC guidance on scams is available on GOV.UK, including a list of genuine HMRC contacts to help you decide if the message you’ve received is real.
