  • Self Assessment - Less payments for this year

    I need help with completing my Self Assessment. When I checked the calculation for the 2023-2024 tax year, I noticed that the total amount due wasn't reduced to account for the advance payments I made, as required by last year's Self Assessment (2022-2023). For example, the first payment due by 31 January 2024 and the second payment made by 31 July 2024. I have a record in my account showing that my tax for the 2023-2024 tax year should have been reduced by these payments. I haven't submitted my tax return for 2023-2024 yet, and I'm wondering when these advance payments will be reflected in my calculation
