I need to complete a self assessment tax return for 2023/24. At the start of that financial year I was still an employee and was made redundant and received a PILON payment that meant I paid a significant amount of tax at the time as it took me into the highest tax threshold. After 4 weeks, I applied for a refund of some tax and confirmed that I would not be returning to employment within the same financial year, which I did not. I started working as a private hire taxi driver in Sept 2023. I have all my income and expenses accounted for with detailed mileage logs so I can apportion the relevant parts of my expenses accordingly (fuel and maintenance etc). I am unsure as to how to deal with the tax refund from my employment PAYE if anything. It doesn't exist in my PAYE tax summary at all. The amount of tax shown in that section is the same as on my P45 from when that employment ended. But I had a refund over just over £4000. Surely that should be visible in my tax summary for the year or be adjusted in the figure showing the tax I paid?
