Completing the computations template – Introduction
The computations template will let you enter information about your profit and loss account and trading account and will automatically fill in most of the CT600 (short) return form for you.
The 'Computations Introduction' page explains who can and can't use the HMRC computations template and tells you where to find further information if you need it.
If you don't use the computations template then you must attach your computations in iXBRL (inline XBRL) or PDF format.
