IRS Scam Call? How to Spot Fake IRS, HMRC, CRA and ATO Calls

An IRS scam call follows a script that barely changes: you owe back taxes, a warrant is about to be issued, and the only way to stop it is to pay right now. The same playbook is used against taxpayers in the UK with HMRC, in Canada with the CRA and in Australia with the ATO. The good news is that all four agencies publish clear rules about how they contact people, and those rules make most scam calls easy to spot.

Why tax office scams work

Tax is complicated, the penalties are real, and very few people are certain their affairs are perfect. Scammers exploit that uncertainty with three ingredients:

• Fear — threats of arrest, deportation, frozen bank accounts or a cancelled tax number.
• Urgency — the problem must be fixed on this call, before you can think or ask anyone.
• An odd payment route — gift cards, cryptocurrency, wire transfers, payment apps or bank transfers to an account that is not the agency's.

Scammers often spoof caller ID so the call appears to come from a real government number, and robocalls frequently open with a recorded message telling you to press 1 or call back urgently. A matching caller ID proves nothing.

How to spot an IRS scam call

The IRS generally makes first contact by letter through the US Postal Service. It may call or visit later, usually after you have already received correspondence about the issue, and it does text or email people who have chosen those channels for specific services. According to the IRS, it will not:

• Demand immediate payment by gift card, prepaid debit card, wire transfer or cryptocurrency.
• Threaten to have you arrested by local police or other law enforcement for not paying.
• Demand payment without giving you the chance to question or appeal the amount.
• Ask for credit or debit card numbers over the phone on an unexpected call.

One wrinkle: the IRS does pass some overdue accounts to a small number of private collection agencies. When that happens, the IRS sends you a letter first, the agency follows with its own letter, and any payment still goes to the US Treasury, never to the agency. To check whether you owe anything, log in to your IRS online account by typing IRS.gov into your browser, or call the IRS on the number listed there.

Report IRS impersonation calls to the Treasury Inspector General for Tax Administration (TIGTA) through its website, and to the FTC at ReportFraud.ftc.gov. Forward suspicious emails claiming to be from the IRS to phishing@irs.gov.

HMRC scam calls in the UK

HMRC does phone people, so a call is not automatically fake. What gives scammers away is the content. HMRC says it will not threaten you with arrest or prison, demand payment by gift card, voucher or cryptocurrency, or ask you to pay into a personal bank account. Common scripts include an unpaid tax bill with a court case starting today, a suspended National Insurance number, and a tax refund that needs your bank details.

Where to report HMRC scams

• Phone calls — use the Report a suspicious HMRC phone call form on GOV.UK.
• Texts — forward them to 60599. You will be charged your network's standard rate.
• Emails — forward them to phishing@hmrc.gov.uk, then delete them.
• Messaging apps — take a screenshot and email it to phishing@hmrc.gov.uk.

To check a genuine tax position, sign in to your HMRC online account or the HMRC app, reached by typing the address yourself, or call HMRC using the number on GOV.UK.

CRA scam calls in Canada

The Canada Revenue Agency does call taxpayers, and its employees are expected to give their name and a phone number when they do. The CRA says it will never:

• Demand immediate payment by Interac e-Transfer, cryptocurrency, prepaid credit cards or gift cards.
• Threaten arrest, deportation or police involvement, or use aggressive language.
• Send refunds or payments by text message, or text you a link to claim one.
• Ask for personal or financial information by text or email.

If a caller says they are from the CRA, hang up and check your account in My Account, or call the CRA on a number from canada.ca. Report scam attempts to the Canadian Anti-Fraud Centre online or on 1-888-495-8501.

ATO scam calls in Australia

The Australian Taxation Office warns that scammers use calls, texts and emails, sometimes with pre-recorded messages threatening arrest. The ATO says it will not send you an unsolicited SMS containing a hyperlink, ask for your tax file number, bank details or myGov login by email or text, or demand payment by gift card, cryptocurrency or a direct transfer to a personal account. Genuine ATO emails come from addresses ending in ato.gov.au, and many messages are delivered to your myGov inbox rather than by text or email.

If you are unsure whether a contact is genuine, do not reply. Call the ATO's dedicated scam line on 1800 008 540 to verify or report it, and report the scam to Scamwatch as well. If you have shared personal details, contact your bank and IDCARE, Australia's free identity and cyber support service.

Texts and emails: the other half of tax scams

Calls are only one channel. Around tax deadlines and refund season, all four agencies warn about texts and emails offering a refund or warning of a penalty, with a link to a fake sign-in page. The page collects your government login, bank details or card number, and sometimes a one-time code that lets the scammer into your real account. The rule is the same as for calls: never use the link. Type the agency's address yourself, or open its official app, and look for the message in your secure account inbox.

Scammers also pose as tax advisers or refund agents on social media, offering to speed up a refund for a fee or to fix a problem with your account. A genuine adviser will not ask for your agency login password, and the tax office will never contact you through a direct message on a social network.

Common tax scam scripts

• The warrant call: you owe back taxes and officers are on their way unless you pay now.
• The refund text: you are owed a refund and need to click a link to claim it.
• The suspended number: your Social Security, National Insurance or Social Insurance Number has been linked to crime and will be cancelled.
• The wrong return: there was a mistake on your return and you must pay a penalty before the end of the day.
• The fake audit: an investigator needs to confirm your identity, starting with your date of birth and tax number.

What to do if you get a tax scam call

1. 1Hang up. Do not press any keys and do not call back the number they give you.
2. 2Check your position yourself through the agency's official website or app, reached by typing the address, not by following a link.
3. 3If you are curious about the number that called, a free lookup on WhoCallsMe can show where it is registered and whether others have reported it. Remember that a government number on your screen may have been spoofed.
4. 4Report the call to the channels listed above for your country.
5. 5If you paid or shared details, contact your bank immediately and change any passwords you gave out.

Gift card payments in particular can be very hard to recover, so speed matters. Contact the gift card company straight away with the card numbers and receipts; some retailers can freeze funds that have not yet been spent.

The one rule that covers all four agencies

No tax authority will make you pay on the spot, by an unusual method, under threat of arrest. If a call has any one of those features, it is not the IRS, HMRC, the CRA or the ATO, however convincing the caller sounds and whatever the caller ID says.
