My friend submitted his 18/19 tax return on 31st May 2020. 4 months late
At the time he submitted return there was a late penalty fee of £100 and nothing else.
He had settled the bill along with tax liability and thought that was that. However HMRC have recently written to him (last 2 weeks) and added additional late payment fees and interest charges. I've told him that as the returns were late they had the right to charge but his bone of contention is that they should have added these charges at the time he submitted his return.
He is planning to appeal. I guess my question to you guys is, in your experience, does he have a prayer?
