About the HMRC

Her Majesty’s Revenue and Customs (HMRC), formerly known as the Inland Revenue, is the main tax office of the United Kingdom government and is responsible for collecting income and national insurance contributions from UK citizens. HMRC also oversees the distributions of tax-related welfare schemes such as working tax credits and child benefit.


HMRC General Enquiries – 0300 200 3300

You should phone the HMRC on their national UK general enquiries contact number 0300 200 3300 to discuss an issue with your income tax payments or to clarify which tax bracket you fall under. Alternatively, you can call this number to ask for a rebate if you are entitled to refund following an overpayment of council tax. You should use this number to discuss which tax bracket you fall under, particularly if you are submitting a return form under the self-assessment system. Alternatively, you may prefer to ask how to register an online HMRC account so you can log into to manage your income tax manually. You can also contact Her Majesty’s Revenue and Customs customer services for support regarding PAYE for employers or working tax credits but may be directed to a specialist enquiries helpline to do so.


National Insurance Enquiries – 0300 200 3500

You can also contact the HMRC national insurance telephone number 0300 200 3500 if you need to order a replacement card or to receive a statement of your annual payments. However, if you have unpaid on your national insurance contributions then your state pension entitlement may be affected. Self-employed workers should therefore ensure that they are paying towards their national insurance bill on top of their income tax when completing their self assessment tax form.


When to Call

The HMRC runs 03 contact numbers meaning that any calls to the customer service or national insurance team will be charged the same standard per-minute rate as any other local call made from a UK mobile or landline. You will be able to contact the HMRC during their opening hours of 8am-8pm Monday-Friday and 8am-4pm on Saturdays.
