I attempted to change my cost of sales (via the P&L) for April 2015 and was prevented because I had already made a tax return. So I deleted the payments for P30 and VAT3 in question. This however did not result in allowing me to adjust my Cost of Sales and also I don’t seem to be able to find the P30 and VAT3 in question to remark them as paid. I did this before making retrospective changes and the unpaid taxes appeared on the home page in red but not this time for some reason…
Have I made a complete nuts of this? Also any idea how I change my Cost of Sales figure for April?
