Claiming Higher Rate Pension Relief for previous tax years

Hi, Looking to claim higher rate pension relief on past 4 years pension contributions. For the years in question I have previously submitted a Tax Return, will claiming relief (via writing in to HMRC) cause a penalty to be issued due to the original return being incorrect or submitted late? Thanks.

Hi, Does anyone happen to know the answer to this question? Any help much appreciated, thanks.

No. An innocent oversight which means you've paid too much tax isn't a target for HMRC!

Hi Bobbin Along,
No, if the original tax return was filed by the due date there will not be a late filing penalty.
There will not be a penalty for the amendment. 
Thank you.
