Dormant accounts:

When there is a long accounting period where the company is dormant for a portion of the accounting period you will need to follow the process for a long accounting period, and remove the apportionment option (see instructions below), so that you can manually allocate the figures to the correct period.

The system will always create the CT600 return for a 12-month period first, followed by the remaining shorter period.

Where the dormant period is the initial few months (less than a year) edit the accounting periods in the client/case details tab and within the tax return manually enter the values in the adjustments to trade profit tab to force this to be the second return for the non-dormant period.

Make sure that you have deselected the ‘apportionment‘ option before creating the second return (see below for instructions).

Click + New Tax Return from within the Tax Returns tab and type in the dates for the earlier part of the period. Do not include the accounts with this return, but remember to select from the drop-down list on the company information screen within the data input tab, ‘Not included – submitted with accompanying return’ or ‘Not included – company dormant.

The dormant period will only be linked by the date for the return and the fact that you have selected ‘submitting more than 1 return‘ for both returns on the Company information data sheet within the data input tab.

To remove the Apportionment option

When you remove the option for apportionment in the trading profits section, the link between the two returns will be removed and the costs will need to be entered manually.

To deselect the option, select the Trading profits data sheet, under the Trade summary tab, click Change

You should see the full amount for the period charged to this 12-month portion of the return.
