Corporation Tax managed with accuracy and commercial awareness.

Corporation Tax compliance, CT600 preparation and practical planning for UK companies that want clarity over liabilities, deadlines and available reliefs.

UK-focused advice Named point of contact Clear deadlines and responsibilities Support that scales with you

Overview

Compliance completed properly, with tax considered throughout the year

Corporation Tax should not be treated as a once-a-year filing exercise. Business decisions, financing, remuneration, capital expenditure, losses and group arrangements can all affect the final position.

CBM Accounting combines annual compliance with forward-looking advice. We prepare the tax computation and Company Tax Return, reconcile the result to the statutory accounts, explain the liability and identify relevant planning points before deadlines become urgent.

Frequently asked questions

Questions clients often ask

Every situation is different. These answers provide a practical starting point, and we confirm the position after reviewing the facts.

Ask our team a question
What is included in a Company Tax Return?

A Company Tax Return normally includes the CT600, relevant supplementary pages, statutory accounts, tax computations and supporting information required for the company circumstances. We coordinate the return with the final accounts.

Can you estimate Corporation Tax before the year end?

Yes. A forecast can be prepared from management accounts, expected adjustments and planned transactions. It remains an estimate until the final accounts and complete tax information are available.

Will you identify tax reliefs automatically?

We consider reliefs relevant to the information and activities made known to us. Some claims require specialist technical work and detailed evidence, which we scope separately before proceeding.

Can you amend a previously filed return?

Where the statutory amendment window remains open, we can review the original return, prepare the correction and explain any tax, interest or disclosure consequences.

Do you deal with HMRC queries after filing?

Routine correspondence can be handled under the agreed engagement. Formal enquiries or investigations are assessed separately because the work and risk can vary significantly.
