Simple Assessment 2022/2023 & Self Assessment 2023/2024

I have requested a self assessment due to tax payable on Interest for last tax year 23/24. Have now been advised that my simple assessment charge for 22/23 has now been cancelled. I have yet to submit my tax return for this year but do not understand why my tax for 22/23 is now being looked at. I am up to date with my tax for 22/23 and nothing is owed. Is the simple assessment cancelled as i am now doing a self assessment instead, if so why go back to previous tax year? Any advice is welcome.

Hi,

It could be that, when you registered for Self Assessment, you registered to file for 2022 to 2023 as well. To allow us to review this for you please contact our Self Assessment team.
