“As you can see I paid my tax bill on the 18 January this year. I assumed that you wouldn’t have asked for a payment if the payment wasn’t finalised i.e. my tax assessment had been received by you and accepted. I enclose the proof of my payment. I finished the 100% submission once you pointed it out in your last letter.”
“I attempted to file my tax online on the18 January 2017 . On that date your website calculated that I owed£141.60 tax and allowed me to pay it directly there and then. After I was later informed that I no longer owed money I rang the self-assessment office to question this. The man I spoke to suggested that there may have been a change in the NI calculation system which may have accounted for the difference in figures. I assumed that my tax assessment had been completed when I paid my bill, as I assumed I wouldn’t have been asked to pay otherwise as the figure wouldn't have been finalised. I feel it unfair that HMRC have come to the conclusion that they can’t reduce my penalty, when you are part judging me on what your system calculated my tax liability after18/01/2017 and not on18/01/2017 when I paid it.”
