Look, let’s be real. Nobody actually wants to call the tax office. It is usually a task born out of necessity, confusion, or a slightly terrifying brown envelope landing on your doormat. If you are searching for the HMRC phone number, you’re probably already halfway to a stress headache.
Tax is complicated. The UK system, managed by His Majesty’s Revenue and Customs (formerly Her Majesty’s Revenue and Customs, though many still use the old terminology out of habit), is a massive machine. It’s a beast. Dealing with it requires patience and, more importantly, the right digits to dial so you don't spend forty minutes listening to Vivaldi on loop only to realize you’re in the wrong department.
Which HMRC Phone Number Do You Actually Need?
There isn't just one "red phone" sitting on a desk in Whitehall. HMRC is siloed into specific departments. If you call the VAT line about your Personal Tax Account, they basically can't help you. It’s frustrating, but that’s the bureaucracy we live with.
For most people, the Income Tax helpline is the big one. This is where you go for PAYE queries, changing your tax code, or asking why your paycheck looks smaller than it did last month. The main number for this is 0300 200 3300. If you are calling from outside the UK, you’ll need +44 135 535 9022.
But wait.
Are you a business owner? If you’re dealing with Corporation Tax, that’s a different door. You’ll want 0300 200 3410. Self-assessment? That’s 0300 200 3310. See the pattern? They all start with 0300, which is great because it’s generally included in your mobile minutes, but the tail end changes depending on your specific brand of tax misery.
Timing is everything (honestly)
You might think calling at 8:00 AM sharp is the genius move. Everyone thinks that. Consequently, the lines are slammed immediately.
Usually, the "sweet spot" is mid-week. Tuesdays to Thursdays, specifically between 10:00 AM and 11:30 AM, or late afternoon around 3:30 PM. Avoid lunchtimes. Never, ever call on a Monday if you value your sanity. Mondays are when everyone realizes they forgot to deal with their tax over the weekend and they all dial in at once.
Also, keep in mind that HMRC has been pushing people toward their digital services. They’ve actually cut back on some phone staff to bolster the app and web chat. It’s a polarizing move. Some people find the app easier; others just want to talk to a human being who can explain why their "Underpayment" notice is five grand higher than expected.
The Scams Are Real: Don't Get Fooled
This is the part where I have to be a bit serious. Because the HMRC phone number is such a high-traffic search term, scammers have a field day.
You’ve probably seen the "number masking" trick. Your phone rings, and the caller ID says "HMRC." The person on the other end sounds official. They might even have a bit of a stern tone. They’ll tell you there is a warrant for your arrest or that you owe immediate money that must be paid via—and this is the giveaway—gift cards or a quick wire transfer.
HMRC will never, ever ask for payment in iTunes vouchers. They won’t threaten to send the police to your door in the next ten minutes. If you’re unsure, hang up. Go to the official GOV.UK website, find the number there, and call them back manually. Don't trust the "press 1 to speak to an agent" prompt from an unsolicited call. It's a trap.
Tax Credits and Child Benefit
If you’re trying to sort out family-related finances, the numbers shift again.
- Tax Credits: 0345 300 3900
- Child Benefit: 0300 200 3100
These lines are notoriously busy. If you’re calling about a new claim, have your National Insurance number tattooed on your brain (or at least written down). They won't even talk to you without it. It’s the skeleton key to your entire financial identity in the UK.
What to Have Ready Before You Dial
Nothing kills the mood faster than getting through to a real person after twenty minutes on hold and then realizing you don't have your P60.
You need a "Tax Kit" ready. At a minimum, have your National Insurance (NI) number. If you’re self-employed, have your Unique Taxpayer Reference (UTR). It’s that ten-digit number that appears on every piece of paper HMRC sends you.
I’d also suggest having your last three payslips or your most recent P60. Sometimes they ask security questions based on your income or your employer's name. If you fumble these, they might refuse to speak to you for security reasons. It’s a pain, but they're protecting your data.
Is the Web Chat Better?
Kinda.
HMRC’s "Digital Assistant" is basically a chatbot. It tries to answer basic questions by pointing you to help guides. If you get stuck, you can sometimes trigger a "talk to an advisor" option, which connects you to a human via text.
The benefit? You can multi-task. You can make a sandwich while you wait for the "Agent is typing..." notification. The downside? It’s harder to explain complex, nuanced problems over text than it is via a quick conversation. If your tax issue involves multiple years, complex relief claims, or overseas income, stick to the phone.
Dealing with the "Old" Name
You might still see people searching for Her Majesty's Revenue and Customs phone number. Since the passing of Queen Elizabeth II, the department officially became His Majesty's Revenue and Customs.

Does this change the phone number? No.
Does it change the branding? Mostly.
Does it change how they tax you? Sadly, not at all.
Whether you call it HMRC, the Inland Revenue (which is a very "old school" way to put it), or the Tax Office, the 0300 numbers remain the gold standard for contact.
Why You Might Be Stuck on Hold Forever
It’s easy to blame the person on the other end, but the reality is that HMRC is massively under-resourced for the volume of calls they get. In recent years, wait times have ballooned. During peak seasons—like the run-up to the January 31st Self-Assessment deadline—wait times can exceed an hour.
If you are calling in January, Godspeed. You are entering a war zone.
The department has been trying to pivot. They want you on the HMRC app. They want you using the Personal Tax Account. Honestly, for simple things like checking your tax code or updating your address, the app is actually decent. It saves you the hold music. But for "I think I’ve been overcharged by £2,000," the app isn't going to cut it. You need a human.
Actionable Steps for Your Next Call
Don't just dial and hope for the best.
First, verify the number on the official GOV.UK portal. Never trust a number from a random pop-up ad or a weirdly formatted "directory" site that charges you £5 a minute.
Second, check your "Personal Tax Account" online first. Many questions about tax codes or previous earnings are answered there with zero wait time.
Third, if you must call, write down the date and time you spoke to them and the name of the advisor. HMRC records calls, but having your own log is vital if you need to dispute something later.
Finally, if you’re a high-earner or have a complex business structure, consider whether calling HMRC is even the right move. Sometimes, you’re better off calling an accountant. They have "agent dedicated lines" that are sometimes (though not always) faster, and they speak the "tax language" that can resolve an issue in five minutes that might take you five hours to explain.
Get your papers in order. Charge your phone. Put it on speaker. And maybe have a biscuit ready. It's going to be a long one.

If you're calling from abroad, generally replace the '03' with '+44 1'. Check the specific department's international line as they vary slightly by region. Be aware that 03 numbers are charged at local rates, but calling from a mobile can be free if you have inclusive minutes. If you’re out of minutes, it’s going to cost you.
Next Steps:
- Check your most recent correspondence for a direct "case worker" number, as this bypasses the general switchboard.
- Log into the HMRC app to see if your query can be resolved via the "Check your Income Tax" tool.
- Ensure you have your 10-digit UTR or your National Insurance number physically in front of you before hitting the call button.
