What is Child Tax Credit?

Child Tax Credit is a benefit available in the UK to help with the cost of raising a child. It is a tax credit which can be offered on top of child benefit and can be paid to families whether they are in or out of work. The credit is integrated with working tax credit, which also provides assistance for childcare costs. You may be eligible to receive a Child Tax Credit for each child you are responsible for if they either are under 16, or under 20 and in approved education or training.

What can I get help with when I call the Child Tax Credit contact number?

Upon calling the Child Tax Credit contact number you can find out whether you are eligible for the benefit, how to claim the benefit and the amount that you could receive. You should also make a call to the contact number if you are already claiming the tax credit and need to update your personal details, such as in the event of a change of address or employment status. 

If you claim Child Tax Credit you will have to renew your claim each year - this can also be done over the phone.
