  • Using tax code in Self assessment

    Hello Admin, I'm in the process of completing my 2023/24 self-assessment but confused as to how my tax code factors into the tax calculation. My final tax code notice has tax code of 1933L (i.e. higher than the default 1257L). The 1933L code has been used by my employer for PAYE, The amount of tax paid through PAYE appears to be correct as per a 1933L code. The PAYE notice has following details: ------------------- Your tax-free amount Personal Allowance £12570 Personal Pension Relief £6762 Total £19332 Total tax-free amount £19332 Tax code 1933L -------------------------- As others have noted (e.g. https://community.hmrc.gov.uk/customerforums/sa/1923338f-6555-ed11-97b2-00155d9c9a65), the self-assessment tax calculation is based on the default 1257L. Can you please advise whether I need to claim "Personal Pension Relief" of "£6762" in self-assessment? If so, which field/section do I need to use to claim it? Thank you for your help.
