Hi all - I am just trying to submit my CT600. I usually do this through the HMRC online portal with no issues. However, this time as I have received more than £1,000 in non trading income (this is from the CRJS furlough income) it is saying that I have to submit using a software supplier, and furthermore my accounts need to be iXBRL format. I don't have my accounts in this format as I use spreadsheets to record my P&L and Balance Sheet (I do my own accounts). Does anyone have any advice please as suppliers to use / how to convert to iXBRL please ? much appreciated.
