What is a CT600 form?

Definition of a CT600 form

A CT600 form is part of a Company Tax Return. The form and other supporting documents constitute the Company Tax Return, which must be submitted to HMRC if a company receives a ‘Notice to Deliver a Company Tax Return’. Limited companies use the information in a CT600 form to calculate the Corporation Tax that they owe.

What’s the difference between a CT600 form and a Company Tax Return?

A completed CT600 form is only one part of a Company Tax Return, which also includes supplementary information such as the company’s accounts and tax computations. More information about completing a Company Tax Return can be found on the government’s website.
