Can HMRC threaten me with immediate arrest for unpaid tax the first time they contact me?
No. HMRC does not threaten arrest on a first contact, and certainly not by phone. Immediate arrest threats for tax debt are a hallmark of impersonation scams.

Explanation
HM Revenue and Customs follows a defined compliance and enforcement process. It issues formal written assessments, provides time to respond or appeal, and offers payment plans before any enforcement action is taken. Criminal prosecution for tax matters is reserved for deliberate fraud cases and follows a lengthy formal investigation — not a sudden phone call.
Scammers impersonating HMRC are active year-round and intensify around self-assessment deadlines. They call, text, or email claiming you owe an immediate tax debt and that you will be arrested, have a county court judgment registered, or have your assets seized if you do not pay within hours. The urgency prevents you from verifying the claim through official channels.
HMRC will never demand payment by vouchers, gift cards, cryptocurrency, or bank transfer to a personal account. It will never threaten criminal prosecution on a first contact call. It will always be willing to give you the official helpline number so you can call back and verify. Any caller who refuses to allow you to verify the call is not from HMRC.
If you receive such a communication and are unsure whether you have a tax liability, log into your HMRC Personal Tax Account at gov.uk or call the official HMRC helpline.

Frequently asked questions
How does HMRC actually contact people about tax debts?
HMRC uses letters, your Personal Tax Account, and sometimes phone calls — but phone calls come after written contact and you always have the right to verify the debt and arrange payment without threat of immediate arrest.
I received a letter, not a call — could that still be a scam?
Fraudulent HMRC letters do exist. Check the address, reference number, and contact details against those on the official gov.uk website. Genuine HMRC letters will direct you to your Personal Tax Account, not to a third-party payment service.
