Deal with long accounting periods

The computations and tax return will show the amounts apportioned on an amounts time basis, but the Capital Allowance figures will still be entered for the accounting period and not the period of accounts.

Where the accounts are for longer than a 12 month period, you need to submit two CT600 returns.

1. Go to Clients > Client List and find the required client.

2. From the Corporate tax returns widget on the client dashboard, select the required return. The Status tab for the return is show by default.

3. On the Check & File tab, select Accounts approved. These are fully amendable until submission to Companies House, even after approving the accounts.

4. Select Attach.

5. Select Create Tax Return. The return information is auto-populated with the dates for the first 12 months of the accounting period.

6. Select Update amounts to tax return, or Skip to ignore this process.

7. In the tax area, select the Data input tab, then select the Company information section.

8. Select Making more than one return now? then select Save changes.

9. Select the Trading profits section. The full accounting period is displayed with amounts apportioned for the period. Complete the Capital Allowances and other details as required.

Now you have completed the return covering the first 12 months of the accounting period, follow these steps again, creating another return covering the remaining time period.
