Last year i submtitted a Pension Scheme Return to HMRC in respect of my boss' SSAS pension scheme for the year 2017/2018 and I have realised recently that I made a mistake. The return is informational only but we still had to sign a declaration that the information is correct and prosecution is a possibility in the event of any false statements. I filed the return online and there is a facility to go in and amend it. My question is, can I amend the error without any risk of penalty? Thanks
