UK Tax Questions? Ask a UK Tax Advisor for answers ASAP
Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to assist with your question.
You appeal simply by writing a letter to the tax office who sent you the Self Assessment Penalty communication. If you received a form requiring you to self assess then you must complete the SA100 and all necessary additional return forms and send to HMRC in the envelope provided. Most people, however, do not ever have to self assess and if HMRC have not required you so to do then you are only required to complete the process if you are in receipt of income which has not been taxed at source.
If you have a late payment then HMRC should have sent you a statement showing the amount owing and why. If this has not happened you should explain to the office which issued the letter the fact that you are not aware of any outstanding tax. HMRC have already publicly toned down their penalty regime so a well constructed letter should resolve the problem.
I do hope that I have been able to show you a way forward in this matter.
