CT600 – Company Tax Return

A company tax return must be submitted using HMRC’s Company Tax Return Form (CT600) or another approved method.

HMRC’s guidance titled ‘The Company Tax Return guide’, has recently been updated and explains:

  • how to complete the Company Tax Return form (CT600); and
  • what other information you need to include in your return.

The information for boxes 630 and 631 has been updated to include what figure to enter if there is no previous accounting period. In addition, the listed conditions on the energy technology list website for designated environmentally friendly machinery and plant has been updated. Information has also been added to the small profit rate or marginal relief entitlement to support completion of the tax return.

The submission must include the company’s self-assessment return alongside details of any trade and other losses such as capital losses. The accounts must be submitted using the iXBRL data standard. A Company Tax Return is not just form CT600. It also includes any supplementary pages, the company’s accounts and tax computations.

The statutory filing date to submit a company tax return is usually the later of 12 months after the end of the accounting period or 3 months after receiving a notice to deliver from HMRC. If a company delivers its Company Tax Return late it may be subject to a penalty.
