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.

Hi
You would claim the personal pension relief if your pension contributions were taken from your net pay and you are a higher rate tax payer. On the online Self Assessment form in the tailor your tax return section you would answer yes to the question- Did you make contributions towards a personal pension or retirement annuity? This will open the section to declare the pension contribution made to receive the tax relief.

Not HMRC....n.b. the amount in your code is not the tax relief you claim. That is an estimate HMRC have given based on previous information. IF you are entitled to claim tax releif on pension contirbution you would enter the amount of the contribution in the tax year (which is often different than the coded figure) in whichever section is relevant by reference as to whether your pension contributions are within a company scheme (and whether before or after tax) and/or whether external to the company and SIPP etc.
