I'm posting here as it's seems virtually impossible to get through to HMRC and I can't find the information I need online.
In the tax year 2020/21, I received child benefit for youngest DC for 6 months before he left higher education. As I earn over £50k (I'm PAYE), I have to complete a self assessment form online. I did this in November last year and it came back saying I owe over £1k in tax. How can this be right when I only received just over £500 in hold benefit?
I've tried to speak to HMRC but each time have had to hand up after being on hold for over half an hour and their online chat never seems to be working. All I can find on the website is information about how to pay, but nothing about how to query the calculation.
Does anyone have any experience of this or know who I can speak to? Thank you.
