If you're putting the final touches to your tax return ahead of next week's deadline, you'll need to be on your guard against scammers impersonating HM Revenue and Customs (HMRC).
The tax office is regularly targeted by fraudsters sending out dodgy emails, texts and letters, and making scam calls to unsuspecting taxpayers.
In the year to November 2023, HMRC received more than 200,000 reports of scams from members of the public, up 9% year-on-year.
Read on for the lowdown on the latest tactics used by scammers impersonating HMRC.
Our emails will alert you to scams doing the rounds, and provide practical advice to keep you one step ahead of fraudsters.

In 2023, HMRC worked with Ofcom to remove 324 phone numbers that were being used for tax office impersonation scams.
Dodgy calls commonly come from withheld numbers or mobile numbers, and contain an 'urgent' pre-recorded message for the recipient.
One example involves an automated message stating: ‘An important letter was sent to you from HM Revenue and Customs that requires immediate attention, please press 1'.
We've also received reports of calls stating the recipient has underpaid tax, is subject to legal action, or that an important document has been returned to HMRC.
If you receive a scam call, don't press anything and hang up. If you do follow the automated prompt, you'll be put through to a scammer who will request your personal and financial details.
Scammers are also sending out dodgy emails claiming you need to log into your tax account or are due a tax refund.
Most recently, we've seen examples of scam emails around P800s, an annual tax calculation that HMRC sends via post. These emails come from the fake address noreply@hmc.co.uk – note the missing 'r' in HMRC.
The emails contain an attachment to download a document. If you do so, a virus may be installed on your device.
Delete the email and follow the steps outlined below to report it.
HMRC says a third of reports of 'suspicious contact' it received in the year to November 2023 related to messages about bogus tax rebates.
Fake HMRC texts have long been in circulation. One recent example states the recipient has 'an outstanding tax refund' and includes a link to 'follow instructions to claim your money'.
This link leads to a phishing website that will request your personal and financial information.
HMRC told Which? that anyone who receives an unexpected message claiming to be from the tax office shouldn't respond immediately.
Fraudsters often try to rush victims into action, so it advices that recipients take their time to check if the message is a scam. HMRC provides advice on common types of scam.
You can help protect others by reporting scam attempts.
If you've lost money to a scam, contact your bank immediately and report the scam to Action Fraud. Call the police on 101 if you’re in Scotland.
