I probably can't dispute it but I just wanted to hear others experiences just in case!
HMRC have said that I have been overpaid by almost £2000. They adjusted my payments and next month I was due to get almost £400 less than last month. Called them and they have stopped this now so it will be recalculated but I feel frustrated because to me the award notice I had in September wasn't clear.
It asked me if the details they had for the year 2019-20 were correct which they were and to let them know if there were any changes. I hadn't changed jobs or anything and I'm on a salary don't do overtime or anything so as far as I was concerned I thought they would calculate the income based on my monthly salary which had remained the same. I earned more in 20-21 because I worked the full year whereas in 19-20 I worked 4 months only (started the job in November). I didn't realise that it was my job to let them know my predicted annual salary for the end of 2021.
I realise it does look stupid to think I was eligible for that much money but I was vaguely aware of a covid boost and just hadn't been on WTC for long so just not familiar with it and as I say just thought they all the information they needed.
I imagine this is just my mistake and there's nothing I can do but I just wanted to find out if anyone else had ever challenged their communications.
