Child Benefit: Rates, Backdating and the High Income Charge
Child Benefit is £27.05 a week for your eldest or only child and £17.90 for each other child. Claims can be backdated up to 3 months, so claim promptly. If your income is over the threshold, the High Income Child Benefit Charge may apply, but it is still worth claiming because you get National Insurance credits while your child is under 12.
