Hello, I found out my son was awarded DLA and I've just moved to Universal credit, So I had to ask Child Tax Credit to backdate. When asking his award she said are you claiming carers Allowance for him. Which I replied I was already receiving carers allowance for my older son in 2022. Which I told them aboutin 2022. Did i have to tell them each tax year? Because I had an Annual review that was automatically renewed. Does that mean I owe Child Tax Credit money?
