What is the HMRC phone number?

HMRC helplines at a glance

HMRC (HM Revenue and Customs) runs a separate helpline for each service. Ringing the right one saves time.

These lines are open Monday to Friday, 8am to 6pm, and closed on bank holidays. Class 4 National Insurance questions go to the Self Assessment line.

Tax credits ended on 5 April 2025. The tax credits line (0300 322 9129) is still open for general questions, Monday to Friday, 8am to 5pm.

What a call costs

Numbers starting 0300 cost up to 16p a minute from a landline and 3p to 65p a minute from a mobile. Your phone package may include them, so check with your provider.

Before you call

• Have your National Insurance number ready.
• Make sure your contact details in your online account are up to date. HMRC may ask security questions.
• For VAT, HMRC says lines are less busy between 8:30am and 11am.

If you cannot use a phone

• Relay UK: if you cannot hear or speak on the phone, dial 18001 then the HMRC number. For example, 18001 then 0300 200 3300 for Income Tax.
• Textphone for National Insurance: 0300 200 3519.
• Extra support: HMRC can give extra help if a health condition or your circumstances make contact difficult.

Other ways to contact HMRC

You can often sort things out without waiting on the phone:

• Digital assistant (webchat): answers questions on PAYE, tax codes, refunds, Self Assessment, VAT and more. It can pass you to a human adviser.
• Your personal tax account or the HMRC app: check your tax code, National Insurance record and Child Benefit payments.
• Post: for Income Tax and Self Assessment, write to HM Revenue and Customs, BX9 1AS. Child Benefit post goes to Child Benefit Office, PO Box 1, Newcastle upon Tyne, NE88 1AA.
• X (Twitter): @HMRCcustomers. Do not post personal details.

Watch out for fake calls

HMRC will never leave a voicemail threatening legal action, and it will never threaten arrest. If a call feels wrong, hang up and ring the number on this page yourself.
