MTD Alert: How to Check If Your HMRC Letter and QR Code Are Genuine

Published Date: February 23, 2026

( Last Updated: September 22, 2026 )

HMRC is sending its final batches of MTD awareness letters right now and fraudsters know it. Every major HMRC campaign brings a spike in copycat letters, fake QR codes, and phishing attempts designed to catch people off guard.

If you have recently received an awareness letter about Making Tax Digital for Income Tax, here is how to make sure the one on your desk is the real thing.

Why It’s Important to Verify HMRC MTD Letters Now

The MTD awareness letters contain a QR code. This is intentional. HMRC uses QR codes in official correspondence to direct taxpayers quickly to relevant guidance. However, fraudsters are known to mimic HMRC letters closely, sometimes substituting genuine links or QR codes with ones that lead to fake websites designed to steal personal information or login credentials.

HMRC consistently ranks as one of the most impersonated organisations in the UK. Those who often receive multiple pieces of HMRC correspondence should treat any unexpected letter with a healthy degree of scrutiny before acting on it.

The GOV.UK Guidance: Verifying MTD Letters and QR Codes

The simplest way to verify any HMRC letter is to check it against HMRC's own list. HMRC publishes a page on GOV.UK that catalogues every letter and leaflet type that legitimately contains a QR code and the MTD for Income Tax customer awareness letter was added to that list.

According to that guidance, the QR code on the MTD awareness letter takes recipients to HMRC’s official step-by-step guide on Making Tax Digital for Income Tax for sole traders and landlords. That destination is hosted entirely on GOV.UK. It does not ask you to log in, does not request personal details, and does not link to any third-party websites.

What to Do When You Receive an MTD Letter

Before scanning any QR code or clicking any link, take a few simple steps to confirm the letter is genuine:

1

Look up the letter on GOV.UK

Search "Check if a QR code on a letter from HMRC is genuine." The MTD awareness letter is listed. If your letter isn't on that page, don't act on it. Instead contact HMRC directly.

2

Check where the QR code actually goes

Scan it first, then look at the URL before tapping through. It should start with gov.uk. Anything else, stop immediately.

3

Never log in via a QR code

Genuine HMRC QR codes link to information pages only. No real HMRC letter will ever ask you to sign into your Government Gateway this way.

4

Don't call numbers on a suspicious letter

If something feels off, find HMRC's number on GOV.UK independently and call that instead.

5

Report fakes to HMRC

Forward suspicious letters or photos of them to phishing@hmrc.gov.uk.

Key Reassurances for Landlords and Sole Traders

If you have already received an MTD awareness letter and acted on it in good faith, there is no need for alarm. The letters are genuine HMRC communications. Here is what you should know:

  • Receiving the letter does not mean you have been automatically enrolled in MTD. You must still register separately, either yourself or through your agent.
  • Not receiving a letter does not mean you are exempt from MTD. If your gross income from self-employment and/or property exceeded £50,000 in the 2024/25 tax year, you are required to comply from 6 April 2026 regardless.
  • Your accountant or agent will not have received a copy. HMRC does not send duplicates to agents, so it is worth forwarding or mentioning the letter to your accountant promptly.

The Bigger Picture: April 2026 Is Close

Once you are satisfied the letter is genuine, the next question is what to actually do about it. With April 2026 just weeks away, landlords and property investors with qualifying income exceeding the threshold need to move quickly from verification into preparation. That means choosing MTD-compatible software, registering with HMRC, and ensuring your record-keeping is set up for quarterly digital reporting.
