Need some help please I have just sat FTX paper and have a query.Pages 127 & 128 of our course text list filing dates for Corporation tax as 23rd of the month. This was the date that I learned and went to my exam with however now people are telling me that this is incorrect as it should be 21st of the month. What is the correct date? There is no mention of 21st in any area of my Corporation Tax Course Text for June exams???? Help
