Different tax codes on payslip and self assessment
Hi, I have the same tax code (1718L) on my payslip, P60 and Personal tax account. However when I complete self assessment, the calculation reverts to the tax code (1257L) leading to additional 000s in tax charges. I thought this was a mistake when it first occurred last year while completing 2022/23 return, but it has repeated when trying to do return for 2023/24. Can someone explain and direct me on what to do please? Thank you
