HMRC VAT Enquiries Number: Official Phone Lines, Opening Hours and Exact Call Charges
The HMRC VAT enquiries number is the phone line 0300 200 3700 that HM Revenue & Customs (HMRC) runs for general VAT questions. It is open Monday to Friday, 8 AM to 6 PM, and closed on bank holidays, according to the GOV.UK page updated 15 July 2026 and checked on 29 September 2026.
Key Takeaways
- The HMRC VAT enquiries number is a 0300 number, so calls are not freephone: GOV.UK gives up to 10p a minute from landlines and 3p to 40p from mobiles.
- Three adjacent numbers do different jobs: 0300 200 3700 for general VAT questions, 0300 200 3701 for VAT online services, and 0300 200 3600 for other HMRC online services.
- The VAT enquiries line cannot take payments or agree time to pay.
HMRC VAT enquiries number: 0300 200 3700 and what the line covers
The HMRC VAT enquiries line handles general VAT questions (such as querying which medical conditions qualify for VAT relief), reports of changes to a business, and Making Tax Digital for VAT, the rules requiring digital VAT records and returns.
It also takes questions about the Fulfilment House Due Diligence Scheme, HMRC’s registration scheme for fulfilment businesses. The same VAT phone line opening hours apply on every working day.

Relay UK is the text-based phone service for callers who cannot hear or speak on the phone. HMRC asks callers to phone only when the online VAT guidance has not answered the question.
Sign-in problems belong on a different line, and the routing table further down sets out which number handles what.
HMRC VAT contact number 0800 or 0300? What does the call cost
The VAT enquiries line uses a 0300 number, which is charged at standard network rates rather than being a freephone line. The GOV.UK VAT enquiries page lists no 0800 number for general VAT questions.
GOV.UK’s call-charges table gives these approximate rates:
- 0800 and 0808: Freephone, free from landlines and mobiles.
- 030, including 0300: Up to 10p a minute from landlines, 3p to 40p from mobiles.
- 0345: Up to 16p a minute from landlines, 3p to 65p from mobiles.
The HMRC VAT contact number therefore costs money unless a phone package includes 03 calls. Phone providers set the actual price, and GOV.UK labels every figure as approximate.
Check the tariff with your phone provider before a long call.
Some third-party guides mix up the 0300, 0345 and 0800 prefixes or give no rate at all. The GOV.UK VAT enquiries page and call-charges table settle both points.
Best time to call: HMRC VAT contact number opening times
HMRC says its VAT phone lines are less busy between 8:30 AM and 11 AM, Monday to Friday. The lines open at 8 AM, close at 6 PM and stay shut on bank holidays.
The GOV.UK VAT page publishes no average wait time, so claims about a busiest date or a best weekday carry no official source. HMRC’s quieter window is the only timing guidance on that page.
If the window does not fit the working day, the non-phone routes covered further down avoid the phone queue.
Before you call: what to have ready and what happens when the line connects
Have the postcode and VAT registration number to hand, because the line asks for both.
- Find your postcode and VAT registration number. (If you are calling to query a supplier’s invoice, you may first need to run a VAT number check by company name).
- Check the address and details in your business tax account, the online HMRC account for a business’s tax affairs. You can log in to your business tax account via the GOV.UK sign-in page. Out-of-date details can fail telephone security.
- Decide in one sentence why you are calling, ready to say aloud.
- Check whether the VAT online account or digital assistant can answer the question first.
- Note the date, time and adviser’s name, and ask for a reference at the end of the call.
The line uses speech recognition software, which asks the caller to say why they are calling before an adviser joins. It may also ask security questions. Problems signing in to VAT online services go to the VAT online services helpline, not this line.
If speech recognition or the phone is difficult
HMRC offers extra support to callers whose health or circumstances make contact difficult, and Relay UK works for those who cannot hear or speak on the phone. GOV.UK’s “Get help from HMRC if you need extra support” page explains the options.
Which VAT number for which problem: 3700, 3701 and other VAT lines
Three adjacent 0300 numbers do different jobs, and each GOV.UK page names the problems that belong on the others.
| Problem | Number | Not for |
|---|---|---|
| General VAT questions, business changes, Making Tax Digital for VAT | 0300 200 3700 | Paying or agreeing time to pay |
| Help using or registering for VAT online services | 0300 200 3701 | Identity-verification problems or tax queries |
| Technical help with other HMRC online services | 0300 200 3600 | VAT online services problems |
| Ordering VAT paying-in slips | 03000 519 206 | Urgent payments |
| VAT claims from businesses based overseas | 0300 322 9279 | Businesses based in the UK |
| Paying late or agreeing time to pay | GOV.UK "Payment problems: enquiries" page | The VAT enquiries line |
The paying-in slips line closes earlier, at 4 PM Monday to Thursday and 3:30 PM on Friday, and slips can take up to six weeks to arrive. The overseas repayments line runs from 8:30 AM to 4 PM, Monday to Friday.
HMRC VAT online services helpdesk number: 0300 200 3701
The VAT online services helpdesk covers help using or registering for VAT online services (if you are unsure whether you need to register, check if your turnover exceeds the current VAT threshold).
It opens Monday to Friday, 8 AM to 6 PM, closes on bank holidays and is quieter between 8:30 AM and 11 AM. The textphone route is 18001 0300 200 3701.
HMRC VAT payment contact number: what the enquiries line cannot do
HMRC states that callers cannot pay, or agree time to pay, on the VAT enquiries line. Time to pay is an arrangement to settle a tax bill late or in instalments. GOV.UK’s guidance on what to do if you cannot pay your tax bill on time explains the route.
Common mistakes on these lines:
- Calling the enquiries line to pay a bill or agree a payment plan.
- Calling 0300 200 3600 about a VAT online problem, or 0300 200 3701 about a tax query.
- Phoning when the online guidance already answers the question.
- Calling without a postcode and VAT registration number to hand.
Other ways to contact HMRC about VAT without calling
- Ask HMRC’s digital assistant, the online chat tool, a VAT question. If it cannot help, ask to be transferred to an adviser, if one is available.
- Sign in to your VAT online account to view payments and outstanding liabilities, submit or view returns and change registration details.
- Businesses that supply to charities can use an online enquiry form. Sign-in is required.
- Check when to expect a reply on GOV.UK’s “Check when you can expect a reply from HMRC” page after writing or asking online.
- Write to BT VAT, HM Revenue and Customs, BX9 1WR, United Kingdom for general questions or letters with attachments. Replies may take longer than 15 working days.
If HMRC needs to reply with confidential details, it contacts the business by phone or post.
How to find the genuine HMRC VAT number and avoid fake calls
The genuine HMRC VAT contact number is the one printed on the GOV.UK VAT enquiries page. Copy it from there, not from a search advert or a third-party listing, and end any unexpected call claiming to be from HMRC.
Call back using the number published on GOV.UK.
GOV.UK publishes a list of genuine HMRC contacts to help decide whether a call, text, email or letter could be a scam.
HMRC never sends a text about a tax rebate or asks for personal or payment details by text. HMRC emails about rebates or requests for such details come only from an address ending hmrc.gov.uk.
Suspicious texts go to 60599 at the network rate, suspicious emails to phishing@hmrc.gov.uk, and suspicious calls through the GOV.UK “Report a suspicious HMRC phone call” online service.
Anyone who has already replied with personal details should email HMRC’s security team at the same address.
Conclusion
For general VAT questions, call 0300 200 3700 between 8:30 AM and 11 AM with the postcode and VAT registration number ready. Use 0300 200 3701 for VAT online services problems and GOV.UK for payment help.
Copy every number from GOV.UK, and recheck the HMRC VAT enquiries number there before dialling if details may have changed.
FAQs
Is the HMRC VAT enquiries number free to call?
No. The HMRC VAT enquiries number, 0300 200 3700, is a 030 number, not an 0800 freephone line. GOV.UK puts 030 calls at up to 10p a minute from landlines and 3p to 40p from mobiles, though a phone package may include them.
Who answers when you call the HMRC VAT line?
Speech recognition software answers first and asks why the caller is phoning. An HMRC adviser then handles the query and may ask security questions, so business tax account details need to be up to date beforehand.
How long does HMRC take to respond to a VAT enquiry?
GOV.UK gives no fixed response time for calls and no average wait figure. Written VAT enquiries may take longer than 15 working days. HMRC says the lines are less busy between 8:30 AM and 11 AM.
Is there a different HMRC VAT number for London or for calling from abroad?
No regional number is listed. GOV.UK gives one UK number, 0300 200 3700, and +44 2920 501 261 for calls from outside the UK.
Can the VAT enquiries line take a payment or set up a payment plan?
No. HMRC states that payments and time-to-pay arrangements cannot be made on the VAT enquiries line. GOV.UK lists a separate “Payment problems: enquiries” contact page, plus guidance on paying tax in instalments.
Contact details reflect GOV.UK pages checked on 29 September 2026, and HMRC can change numbers, hours and call charges at short notice. Readers should confirm current details on GOV.UK before calling.
