I paid off 2021-22 tax by Dec 22. My last payment made in December has since disappeared from my tax overview payments , following an amendment to my tax . Also HMRC owed me about £5000 and told me I was paid up to July 23 and had £1400 in credit towards Jan 24. But in July 2023 , something changed on my account and i had a fine and interest added for late payment of 2021-22 tax which I had paid off early.
I then noticed the £5900 that was paid in Dec 23 is missing from my tax overview payments , but is on my payments made, in a separate page in my account . So, I then was told I owed tax for July when it was previously paid off. I paid £3000 but it still says that I owe money for July , plus £20k for Jan 24 , which is far too much. No one will help and I know I do not owe the tax they say I do. I have sacked my accountant as she will not help, as she said lots of people have the same problem.
HMRC phone lines are down and I need help.
I have submitted an appeal form for the £100 fine in Jan 24 and hope they will look at my case and payments properly. Any advice would be appreciated!
