Hi, I started a started a new Job in May-June 2023 and this was considered a second job as my previous role hadn't fully ended yet. So I was given the Tax code ending in T. For the rest of the year I only had one job, so around 10 months I was taxed for the two jobs rather than the one. This is reflected in my info on my account so I know HMRC are aware and have got the right information. I am expecting my tax code to change for this next financial year but was wondering if I have overpaid or underpaid tax due to the change? TIA
