Fake HMRC Tax Debt Arrest Warrant Threat Scam
Criminals impersonate HMRC enforcement officers by phone or letter, claiming an arrest warrant has been issued for unpaid tax debt and that the recipient must pay an immediate settlement to prevent police attendance at their address. HMRC does not issue arrest warrants for civil tax debt and does not demand emergency telephone payments.

Last reviewed: 8 June 2026
HMRC does pursue unpaid tax through debt collection and, in extreme cases of criminal tax evasion, through the courts. Fraudsters exploit awareness of this to create threatening calls that blend real HMRC terminology — Self Assessment, compliance officers, HMRC Enforcement and Insolvency Service — with entirely false threats of imminent arrest.
Callers posing as HMRC enforcement officers state that a Magistrates' Court warrant has been obtained because the recipient has ignored repeated notices for a tax debt, and that police and bailiffs will attend the recipient's address within hours unless an immediate payment is made. The psychological pressure is intense, particularly for people with legitimate concerns about their tax position.
HMRC's tax debt collection process involves a clear series of written notices, a right to appeal, and options to arrange payment plans. Criminal prosecution for tax fraud is a separate, lengthy legal process. HMRC does not make surprise arrest-threat calls demanding same-day payment to avoid immediate arrest.
How this scam works on the HMRC brand
The call opens: 'This is HMRC Compliance and Enforcement. We have been instructed to inform you that an arrest warrant has been issued in respect of unpaid Self Assessment tax of £4,800. Officers will attend your address at [time] today unless a settlement is received. Press 1 to arrange payment.' Pressing 1 connects to a scammer demanding bank transfer or gift cards.
A letter variant is printed on convincing HMRC-styled headed paper and includes a fake Magistrates' Court seal, a case reference number, and a phone number to call for a 'settlement'. The number connects to the fraudster.
Some callers add that the victim must not hang up and must not seek legal advice until the payment is received, a classic pressure tactic used in arrest-warrant scams across government impersonation campaigns.

Frequently asked questions
Can HMRC issue an arrest warrant for unpaid tax?
Criminal prosecution for serious tax fraud is possible, but it follows a long and documented legal process. HMRC does not issue arrest warrants for civil tax debt, and a surprise phone call claiming police are arriving within hours is a scam.
What is the real HMRC debt recovery process?
HMRC sends reminder letters, then formal demands, then may refer the debt to a bailiff or debt-collection agency. Throughout this process you have the right to appeal, arrange a payment plan, or seek independent advice. Nothing happens without written notice.
I am genuinely worried I owe HMRC money. What should I do?
Log in to your Government Gateway account at gov.uk/hmrc or call HMRC at 0300 200 3300. Do not call any number from a suspicious phone call. Citizens Advice and tax charities such as TaxAid (taxaid.org.uk) can provide free guidance.
