Corporation Tax

Scenario

You might get the following error message when you try to file CT600.
Error message
The period to which this Return's accounts applies does not coincide with the affected From/To dates of the referenced accounts taxonomy

Causes

This error message can have any one of the following causes:
  • The FRS 102 template used for the client is out of date.
  • The report you are using is not one of the default reports.
  • The default report you're using has been amended.
  • The version of Corporation Tax you have installed is not the most recent version.
  • The taxonomy set for your client's accounts in Corporation Tax is not the most recent taxonomy.
We recommend that you try the following 5 solutions in order, until you've resolved the error.

Solution 1: Check you're using the up-to-date FRS 102 template for the client in Accounts Production Advanced

  1. Sign into Accounts Production Advanced with administrator rights.
  2. Select
    Tools
    , then
    Content download
    .
  3. Check if there are templates available to install.
    1. If there are no templates to install, go to Solution 2.
    2. If a
      UK FRS 102
       template is available, install this template.
    3. If after installing the
      UK FRS 102
       template, there are other templates available, you can also install these.
    4. When you've finished installing templates, close the window.
  4. Open the client in Accounts Production Advanced, where the CT600 failed to file.
  5. On the pink message bar at the top of the screen, select
    Update
     to update the client to the new template.
  6. Run the accounts.
  7. Export the iXBRL accounts report.

Solution 2: Check that you're using a default report

  1. Open the client in Accounts Production Advanced (or Accounts Production if you're using that application).
  2. Select the
    Reports
     tab.
  3. Check if you are using one of the following default reports for the client's accounts:
    • FRS 102 Consolidated Financial Statements
    • FRS 102 Dormant Financial Statements
    • FRS 102 Financial Statements
    • FRS 102 Section 1A - Abridged Financial Statements
    • FRS 102 Section 1A - Small Entities
  4. If you're not using one of the default reports, then you'll need to take the following steps:
    1. Open the report that you're trying to file.
    2. Right-click the top folder in the report structure and select
      Properties
      from the context menu.
    3. Select the
      XML Source
       tab.
    4. Replace the existing XML code with the XML code in our replacement XML text file.

      Report template is syntactically correct'
       is shown. 
    6. Select
      OK
       to save and update the report.
    7. Export the accounts, then file them.

Solution 3: Check if the default report you're using has been amended

  2. Select the
    Report structure
     tab.
  3. Right-click the top folder and, if
    Revert to template
     is shown in black not grey text, select it to revert the folder to the default position and update the taxonomy.

    2. Select the
      Template entities
       tab.
    3. Open the template.
    4. Select the
      Report structure
       tab.
    5. Right-click the top folder and, if
      Revert to template
       is shown in black not grey text, select it to revert the folder to the default position and update the taxonomy.
  5. If you needed to revert the template at template level, then you'll also need to take the following steps to republish the template:
    1. Select
      Financial Period Templates
      , then
      Publish current period as a template
      .
    2. Select
