Ways to get in touch with HMRC

HMRC online services and the digital assistant

For Self Assessment, Income Tax, VAT, National Insurance, Child Benefit, Corporation Tax, employer queries and online technical problems, HMRC's contact pages start with its digital assistant. If the digital assistant cannot help, you can ask to transfer to an HMRC adviser if one is available.

Many things do not need a call at all. Your personal tax account, business tax account or the official HMRC app let you check your tax code and employment details, see an estimate of your tax, and manage a Child Benefit claim. If you have already contacted HMRC, you can check when you can expect a reply. If HMRC needs to tell you anything confidential, it replies by phone or post.

X (Twitter)

You can ask HMRC general questions on X by starting your post with @HMRCcustomers. HMRC cannot discuss individual cases there, so do not include personal details. The account answers Monday to Friday, 8am to 8pm, and Saturday, 8am to 4pm.

Webchat

HMRC's webchat is reached through the digital assistant on each contact page, with transfer to an adviser when one is available. There is also a webchat for HMRC's extra support team, for people whose health or circumstances make contacting HMRC difficult (GOV.UK extra support).

Which helpline to call

Self Assessment

Call 0300 200 3310 about your Self Assessment returns, payments, replacements or notices, and about signing up for or using Making Tax Digital for Income Tax. If you use Making Tax Digital software, contact your software provider for technical support, not HMRC (GOV.UK).

For help making a payment, the payment enquiries line is 0300 200 3401. You cannot pay your bill on that number, and you will need your UTR (GOV.UK). Our guide on how to find your UTR shows where it is.

For problems logging in, submitting your return online or error messages, call Self Assessment online technical support on 0300 200 3600, with your UTR to hand (GOV.UK).

PAYE and Income Tax

Call 0300 200 3300 about your tax code, tax overpayments and underpayments, a P800 tax calculation, Marriage Allowance, tax on savings interest, general ISA questions, proof of your UK tax status, or paying the High Income Child Benefit Charge through your wages or pension. Have your National Insurance number with you (GOV.UK).

VAT

Call 0300 200 3700 only if you cannot find the answer in HMRC's online VAT guidance or services. You cannot pay or agree time to pay on this number. Have your postcode and VAT registration number ready if you have one (GOV.UK).

National Insurance

Call 0300 200 3500 about Class 1, 2 and 3 National Insurance, including gaps in your record, credits, refunds, statements and National Insurance abroad. HMRC will not give you your National Insurance number over the phone; it is posted to you and can take up to 10 working days, or you can see it in your personal tax account or the HMRC app. Class 4 National Insurance queries go to 0300 200 3310 (GOV.UK).

Employers

Call 0300 200 3200 for employer help. HMRC can only give general advice if you do not have your Accounts Office reference or PAYE reference number. The employer fax number is 03000 523 030 (GOV.UK).

Corporation Tax

Call 0300 200 3410 for general Corporation Tax enquiries. You will need your company's 10-digit UTR, which advisers cannot give you over the phone. If you have just paid electronically, allow 3 working days for the payment to reach HMRC before calling (GOV.UK).

Child Benefit

Call 0300 200 3100 if the HMRC app does not answer your Child Benefit question. You will need your National Insurance number, and HMRC can only discuss a claim with you or someone you have authorised (GOV.UK).

Tax credits

Tax credits ended on 5 April 2025 and no more payments will be made. For a general enquiry about past tax credits, or to complain about HMRC's tax credits service, call 0300 322 9129, Monday to Friday, 8am to 5pm (GOV.UK).

Technical support

Call 0300 200 3600 for technical problems with HMRC online services, or if your health, disability or circumstances make online services hard to use. Do not use it for tax questions, and VAT online services problems have their own helpline (GOV.UK).

Before you call

  • Several helplines, including Income Tax, VAT, Child Benefit and National Insurance, use speech recognition, so you will be asked why you are calling.
  • Helplines may ask security questions. Make sure your details and address are up to date in your personal or business tax account first, or you could fail telephone security.
  • Have the right reference ready: your National Insurance number for Income Tax, National Insurance and Child Benefit, your UTR for Self Assessment payments and Corporation Tax, and your VAT registration number and postcode for VAT.
  • HMRC says the VAT and Corporation Tax lines are less busy between 8:30am and 11am.
  • If you started a new job and think your tax code is wrong, HMRC asks you to wait 35 days for your new income details to reach it before contacting it.

Getting an accountant to deal with HMRC

You can authorise an accountant or tax adviser to deal with HMRC for you. Once authorised, they can handle your tax affairs, such as submitting your Self Assessment return, and HMRC sends your Self Assessment correspondence to them, except tax bills and refunds. You can also authorise a friend, relative or voluntary organisation to talk to HMRC and help with forms (GOV.UK).

If you only need short-term help with Self Assessment, you can call HMRC with the person helping you in the room, and HMRC will confirm their identity and check you are happy for them to represent you.
