Dear HMRC, I am not looking for specific or tailored advice, but because there is a piece of information on the Income Tax Self Assessment website that is not clear, I hope HMRC can help explain it. The following is just an example. I have completed the tax return for 2023/24, but have not yet submitted it. The calculation result of the tax return is that my tax payable for 2023/24 is £30,000, plus the first payment of 2024/25 is £15,000, and I should pay £45,000 before 31 Jan 2025. However, I have already paid the first payment of 2023/24, which is £10,000, and the second payment is also £10,000. I want to know,if I submit the return, will the tax payable automatically be reduced by the first and second payments? Many thanks.
