Massively Wrong Self Assessment CalculationHi, First I have been trying to reach HMRC by phone for the past 2 hours to no avail. I have filed a nil self-assessment for the years 2021/2022 with the calculation showing that I have nothing to pay. I have not traded at all in this year so everything is essentially 0. Now the calculation came back and it shows that I have 2772 £ to pay while at the same time saying I have nothing to pay. Can somebody help? It is near impossible to resolve this right now.
