Throughout the year 2023-2024 my tax code was adjusted to pay the tax owed from the year 2021-2022. The amount has already been settled through deductions made from all my paychecks as this debt was included in my new tax code for 2023-2024. However, when filing the return the amount in question is added to the total amount payable this year, as if it were still outstanding. If I submit this result to HMRC, what will happen? Will you require me to make that payment, or will it be adjusted and deducted? How can I ensure that there will be no double counting for the outstanding tax? Thank you.
