Overview of Child Tax Credit

Child Tax Credit is a UK welfare benefit that is awarded by HMRC to claimants who are responsible for children who are aged 16 or under, or are under 20 in full-time education or training. Crucially, you don’t have to be working to claim Child Tax Credit and the amount any one person can receive will depend on how many children they are responsible for.  

UK-wide General Enquiries – 0345 300 3900

You should phone the HMRC on their Child Tax Credit general enquiries number 0345 300 3900 to ask for assistance before making a claim for the UK benefit. For instance, callers may wish for assistance when ordering an application form online or request the relevant papers be sent directly to their home address. However, you may first wish to discuss your eligibility for the benefit with a HMRC representative before asking for help with any questions on the application form. It should be noted that you will need your national insurance number on hand in order to complete your application for the benefit. Claimants have the option of managing their Child Tax Credits online or when speaking to an advisor, and should choose the latter if they are having difficulty logging into their internet account. You can renew a successful benefit claim over the phone or even inform the HMRC about any changes to your circumstances that may affect your eligibility for the benefit. If you have already submitted Child Tax Credits claim then you may wish to use this number to monitor the process of your application before asking how much and when you’ll be paid.
