Fake tax demands are a growing scam. Scammers impersonate HMRC (or your local tax authority) and demand payment in cryptocurrency.
How the Scam Works
| Stage | What Happens |
|---|
| 1 | You receive an email, text, or voicemail |
| 2 | It claims to be from HMRC |
| 3 | It says you owe back taxes or face arrest |
| 4 | Payment is demanded in cryptocurrency (Bitcoin) |
| 5 | There’s a deadline — often just hours away |
Red Flags
| Red Flag | Why It’s Fake |
|---|
| Demands payment in crypto | HMRC doesn’t accept cryptocurrency |
| Threat of immediate arrest | HMRC doesn’t arrest by email |
| Short deadline (24 hours) | Artificial urgency |
| Poor grammar or spelling | Common in phishing |
| Generic greeting (“Dear customer”) | HMRC uses your full name |
| Suspicious sender address | hmrc-gov-uk@gmail.com (not .gov.uk) |
| Link to fake payment page | Looks like gov.uk but isn’t |
| Phone number to call back | Scammer on the other end |
| Method | HMRC Practice |
|---|
| Email | Only if you’ve agreed to email contact |
| Text | Only if you’ve opted in |
| Phone | They identify themselves with your UTR |
| Post | Official letters on HMRC headed paper |
| Crypto demand | Never — HMRC doesn’t accept crypto |
What HMRC Will Never Do
| Action | Never Happens |
|---|
| Demand crypto payment | Never |
| Threaten immediate arrest | Never |
| Ask for your seed phrase | Never |
| Ask for your wallet private key | Never |
| Call and ask for your PIN | Never |
| Send a link to “verify your identity” | Never by email/text |
The Crypto Tax Demand Email
| Element | Fake Email | Real HMRC Email |
|---|
| From address | hmrc-tax-refund@yahoo.com | @hmrc.gov.uk |
| Greeting | ”Dear taxpayer” | Your full name |
| Amount | Vague (“significant underpayment”) | Specific amount |
| Payment method | Bitcoin | Bank transfer or cheque |
| Deadline | ”Within 24 hours” | At least 30 days |
| Threat | ”Warrant for your arrest” | Late payment penalties |
What to Do If You Receive One
| Step | Action |
|---|
| 1 | Don’t click any links |
| 2 | Don’t reply or call any number |
| 3 | Don’t send any crypto |
| 4 | Forward the email to report@phishing.gov.uk |
| 5 | Report to Action Fraud |
| 6 | Delete the email |
Other Tax Authority Scams
| Country | Authority | How They Contact |
|---|
| UK | HMRC | Post / personal tax account |
| US | IRS | Post / official portal |
| Canada | CRA | Post / My Account |
| Australia | ATO | Post / myGov |
| Germany | Finanzamt | Post |
All use postal mail for official tax communications, not email demanding crypto.
Bottom Line
HMRC will never demand crypto payment, never threaten arrest by email, and never ask for your seed phrase. Fake tax demands use urgency and fear to make you act without thinking. If you receive a crypto tax demand, it’s a scam. Forward it to report@phishing.gov.uk and delete it. Real tax authorities give you weeks to respond, not hours — and they don’t accept Bitcoin.
