Do forgive me for boring you with cases on how you may be able to avoid having to settle tax penalties (see http://www.breakinglaw.co.uk/search/label/tax%20penalties for the sort of agony I have put you through).
And here's the latest case with my abject apologies. In Lennon v Commissioners for Her Majesty's Revenue & Customs  UKFTT 0220 (TC) the taxpayer had been penalised for failing to put in tax return on time. He was subject to PAYE but his employer had under collected £321 for one tax year and HMR&C decided it wanted a return from the taxpayer. On the taxpayer's appeal against penalties for the lateness of that return, the Tax Tribunal judge ruled that-
- There can't be a valid penalty unless there has previously been a valid notice from HMR&C to the taxpayer to put in a return.
- A tax tribunal has jurisdiction on an appeal of this kind to look into the validity of the HMR&C notice.
- A notice can be given for the purpose of establishing the tax which the taxpayer has to pay for a given tax year.
- In this case, the notice had not been given for that purpose as HMR&C was fully aware of how much tax had to be paid. It was just the uncollected £321.
- Because the purpose of requiring the return was invalid, the notice requiring it was invalid and the penalty based on non-compliance with the notice was invalid.
Please forgive me.
