Higher Rate Pension Relief on historic Self Assessment Returns

Hi there I am a higher rate payer and have submitted self assessments for Tax Years 18/19 through to 21/22. I only recently became aware that I was entitled to higher rate relief on my workplace pension contributions. I was able to claim this relief on my 21/22 self assessment, but am time barred from amending previous returns on the online portal. Please can anyone advise how I am able to claim this relief for tax years 18/19, 19/20 and 20/21? Thanks Rhys

Hi Dafydd,

You are now too late to claim for 2018/19 as this would need to be been claimed by 05/04/23.
For 19/20 and 20/21 you will need to write in with details of the payments made and state that you are claiming overpayment relief. ensure the letter is signed.
This should be sent to
HMRC,
PAYE & Self Assessment

Thank you.
