If your accounts cover a period of over 12 months, you'll need to complete the CT600 for two periods, as follows:

  1. Prepare the accounts for the full period and generate an XBRL version.
  2. Apportion the profit/loss into a 12-month period and the remaining days – using days meets the HMRC guidelines.
  3. Create the first (12-month) period return in TaxCalc (see instructions below).
  4. Create the second (short) period return in TaxCalc (see instructions below).

  6. Click on Create.
  7. Go to Accounts and Computations.
  8. Under I am attaching Accounts..., tick Relating to a different period.
