When a company is incorporated, its incorporation date will be on the day the company was applied to the
Companies House Register. If you want to extend your first year you can do so up to 18 months. However even if you
do not choose to extend your first year, unless your incorporation date was on the first day of the month, Companies house will set the
end date to 12 months + days to the end of the anniversary month.
For example if you incorporated on the 7th July 2018 , Companies House will move your end date to the 31st July 2019. This will then become your Accounting Reference Date (ARD).
This raises a reporting anomaly. HMRC require a Corporation Tax return (CT600) after the end of the accounting period. But as a CT600 can only report up to a maximum of 12 months, you will need to file two CT600's. Companies House however only require a single set of abbreviated Accounts that cover the whole (extended) period.
In the above example year you will would need to create a (HMRC) IXBRL Company Accounts filing for 7th July 2018 to the 31-July 2019 and a CT600 for the 7th July 2018 to the 6th July 2019 and a second CT600 for the 7th July 2019 to the 31st July 2019. You will need to attach the accounts that cover the extended period with either or both CT600 Filings.
Confused? The Steps below hopefully guide you through this situation.
Note: HMRC require full Accounts which includes a Profit and Loss Statement where Companies House only require the statutory declaration and the Balance Sheet.
You can either create the first CT600 and accounts using the QuickStart dialog which after selecting your company, Accounting period start date and company size (Micro or Small) - or alternatively create 2 CT600 filings and IXBRL accounts separately.
In both cases you should end up with 3 Filings in your blotter which will hopefully look like the below:
In this example the accounting year has been extended to cover the period 1st of June 2018 to 31st of December 2019. (19 months)
Note that the first CT600 accounting period starts on the 1st June 2018 and ends on the 31st May 2019 (12 months). The second CT600 starts on the 1st June 2019 and ends on the 31 December 2019 (7 months).
The IXBRL accounts can cover the entire extended accounting period (in our example 1st of June 2019 to 31st of December 2019.) - which makes the filing slightly easier.
The primary question here is normally "what to enter for turnover in CT600 when
accounting year is more than 12 months"?
It's up to you to decide how your attribute your turnover and income across the 2 periods - however generally your records / accounting system should be able to provide what income and expenditure you had for each.
When you are completing the CT600, in the declaration section you will need to allocate the IXBRL accounts that you have created. Note that Box 80 is set to YES; Box 85 is set to NO, and; Box 90 is set to Not applicable. With box 91A being set to the IXBRL Company Accounts. Note: if you have supplied your own IXBRL accounts you can select to upload them in the dropdown menu in box 91A.
Note: Although in this example we had the longer period (the 12 month period) first, it actually makes no difference and therefore you could have the shorter period for the first CT600.
Once you have completed your returns and completed the above you will now be able to submit, you can submit in any order, normally though the CT600 return with the accounts attached is sent first - as if you get rejection errors it better to deal with those first. Once you have submitted both (and hopefully accepted), you will receive emails from EasyDigitalFiling with your IRMark (digital hash) and later (possibly 4-12 hours) an email from HMRC.
When I first wrote this article, we did not submit to Companies House, but due to popular demand we built out to the Companies House interface and you can now also create a Companies House Submission which will fillet (remove the Profit and Loss statement) from your HMRC IXBRL accounts, and add the Companies House IXBRL Taxonomy (yes - Companies House have different IXBRL Tags to HMRC). You can then file with a click direct to Companies House. For Micro Limited Companies you can do this through the Companies House web site for free, but as you will have already made the accounts up on the platform for HMRC, we hope that being able to do this automatically will save you time, ensure accuracy and consistency with what is filed with HMRC, and have all your Accounts filings in one place.
All done - at this stage you will feel like a master. The pressure is off, for another year anyway!
We added to our QuickStart some fuzzy logic to try and work out if your first year has been extended by Companies House,
so if you have used QuickStart it should create the above 3 Filings for you (and a Companies House Filing if you selected
that option also). We did so after a number of people contacted us to say that they had been fined for not filing
the second return, as they had not set there accounting end date correctly.
In some instances you may be able to ask HMRC to start your reporting period after your incorporation date so that you still align with your ARD, but only have to submit a single CT600 (this may have been if you started Trading later after incorporation). Its always worth checking with HMRC. If they do allow you to report for a shorter period, just delete the second CT600 and adjust dates accordingly.
