To access this screen select Reports, Electronic Tax Return.
Select the Corporation Tax accounting period to which the return relates.
Select Live or Test. Where test is selected this will be indicated on the Transmit Internet Return screen.
The default setting will be new. In order to submit an amended CT600, change the radio button to the correct field.
Accounts must be attached unless the user has indicated otherwise and given a reason on the Data Entry - Summary screen.
Due to changes in legislation the program will expect iXBRL Accounts and iXBRL computations to be attached when generating an electronic tax return. If the accounts need to be attached in PDF format, you must tick the option "Accounts attached in PDF format" in the 'Data Entry - Summary' screen to indicate that the accounts need to be attached in PDF format.
A PDF copy of the accounts can be submitted with the return instead of iXBRL accounts in any of the following circumstances;
The return is filed before 01/04/2011.
The return is for a corporation tax accounting period ending before 01/04/2010.
The return for a corporation tax accounting period ending on or after 01/04/2010, but is filed before 01/04/2011.
The company is exempt from iXBRL filing.
Use one of the following radio options to locate the accounts:
Automatically select iXBRL HMRC Copy from IRIS AP - allows IRIS Accounts Production users to attach the HMRC copy of the finalised iXBRL accounts produced within IRIS Accounts Production. IRIS Business Tax will automatically select the HMRC copy of the iXBRL accounts generated within IRIS Accounts Production for users with a relevant licence for the product. To generate a HMRC copy of the iXBRL reports, select the 'Reports - iXBRL' option within IRIS Accounts Production.
Select from Communication Tracking - allows Practice Management users to attach accounts stored within IRIS Communication Tracking.
Select external File - allows the user to click the magnifying glass and browse to find and select an existing iXBRL or PDF document to be attached for the client.
Please note that for CT600 returns submitted on or after the 01/04/2011 for accounting periods ending on or after the 01/04/2010, the accounts must be filed online in iXBRL format.
iXBRL or PDF computations should be attached to the CT600 unless the user has indicated otherwise and given a reason on the Data Entry - Summary screen. There are four options available:
Not included - select this option if computations are not attached.
Automatically select from Communication Tracking - use this option to select iXBRL or PDF documents to be attached to the Electronic Tax Return which have previously been saved within IRIS Communication Tracking.
Generated - if this option is chosen the iXBRL or PDF computation will be generated at run time. The computation will appear on the screen before the CT600 is displayed to give the user the opportunity to check the computation is as required.
Select External File - allows the user to click the magnifying glass and browse to find and select an existing iXBRL or PDF for the client.
Please note that when attaching an iXBRL tax computations for a long Corporation Tax Account Period (CTAP), due to cross checking of the iXBRL document the CT600 the accounting period that the computation relates to must match that shown on the CT600.
In the situation where there is a long CTAP IRIS Business Tax assumes that the computation will be attached to the 1st CTAP submitted. When dealing with a long CTAP there are several options available to attach the computation:
Use the Generate now option to generate the iXBRL computation for the relevant CTAP shown at the top of the screen OR
Use the Automatically select from Communication Tracking option and ensure that when filing for the 2nd CTAP the setting Data Entry / Summary / Computation has not been ticked for the 2nd CTAP period and the reason set to Submitted with accompanying return. OR
When using external software to generate the iXBRL tax computation users are required to ensure the relevant period that the computation relates to has been correctly set in that iXBRL computation produced.
Please note that for CT600 returns submitted on or after the 01/04/2011 for accounting periods ending on or after the 01/04/2010, the computation must be filed online in iXBRL format.
A number of optional attachments can be submitted with the return. Select External PDF to locate an existing PDF for the client or Communication Tracking to attach PDF's which have previously been saved within the communications tracking section.
Please note that where the period of account is longer than 12 months the HMRC will require a company tax return, including a CT600 for each accounting period. No accounting period for tax purposes can exceed 12 months. The first CT600 submitted should have the accounts and computations attached. For any subsequent CT600 covering part of that same period of account the field on page 1 ‘if no accounts say why not’ should be completed with: ‘See CT600 for the period DD/MM/YYYY’.
