I have a client that has lengthened their accounting date from 31 Aug to 31 December. My understanding is that from a Conpanies House perspective my filing date will be pushed out by 4 months but my question is what happens from HMRC perspective? Is the filing date for Corporation Tax 12 months after 31 Aug or 31 Dec? Is it a case that once HMRC are notified it will be 31 Dec? I understand that 2 returns will be required for 12 months and 4 months but it is not clear to me when both returns fall due. TIA

31 Dec for both CT600s but the tax is due 9 months and 1 day after each accounting period.
I suppose you will have to write to them if you haven't filed the tax returns by 1 June and the system has not updated from the change at Companies House. You will need the system to update so your client can use the correct payment reference otherwise the payments won't be allocated correctly.
Why would there be penalties? You mean if you didn't do anything and they were expecting the tax return on 31 Aug? No I wouldn't recommend that, not least because they would repay the tax.
To be fair, they will send out reminders and penalty notices based on the old year end if you don't tell them.
They're rebuttable, but you'll get pestered.
