I'm struggling with the above as it is longer than 12 months.
I have downloaded the pdf to do the ct600, I have filed accounts with companies house separately.
I having problems it isn't giving me this period as an option, it gives me 09/11/2010-08/11/2011, then 11/11/2011-05/04/2012, this misses out a few days, don't know what to do, would you call hmrc and ask why it's not showing the correct periods.
Also if I have already done accounts with companies house do i still need to attach to this pdf (ct600 and calcs)?,
Previously, I've used ftax and vt accounts, but had probs with that, thought hmrc would be a big more straight forward.
yes I have found the period from the website and it's missing 2 days, will check with hmrc why this is, as I am a agent so they should be helpful this time lol
