Underpaid tax included in PAYE coding (Page 2 of 2)

Hi, I'm currently trying to complete the Underpaid tax included in PAYE coding (Page 2 of 2) section. I have not been able to find my PAYE Coding Notice (P2) so am using the information available online. I have a notice of a change of tax code from 28 July 2023 which states we estimate you have underpaid [£X] tax this year. Is this figure used to complete the Underpaid tax included in PAYE coding (Page 2 of 2) section or should it be left as 0 on the basis this relates to the 2023/24 tax year? Many thanks in advance

Hi,

The code issued on 28 July 2023 will be for the current 2023 to 2024 tax year so the details would not be for your 2022 to 2023 Self Assessment tax return. If you are unable to view the 2022 to 2023 tax code online then you will need to contact our Self Assessment team to check the entries for the Self Assessment tax return.
