So I joined a new company in tax year 2022-23. I was given a sign on bonus. We mutually terminated ways in January 2023. It was agreed I was pay them back several thousand pounds. They would then claim back the tax on this they paid, rather than me paying back total with tax. I’m trying to find out where on my self assessment for 2022-23 I would enter this information, to reflect I earned less than my p45 states. Many thanks for your help.
