I completed a self assessment for year 21/22 and owed a few thousand in underpaid tax. This was to be recovered through reduction in personal allowance in tax year 23/24. However my pay has increased since and I will now not have a personal allowance in the current tax year due to earnings so not sure how this will be recovered. My question is when completing the 22/23 assessment for the questions related to underpaid tax how do I answer. The number pulled through from HMRC is £0.00 to both questions?
