Corporation Tax accountant and CT600 filing

UK-wide remote service · London office · Chartered accountant led

What is a CT600?

A CT600 is the company tax return submitted to HMRC. It is supported by the statutory accounts and tax computation, so unresolved accounting information can affect the return.

What we review

The tax work begins with the accounts and the transactions that may need a different tax treatment.

Accounting profit and tax adjustments
Capital allowances and fixed assets
Director loans, interest and related parties
Losses and available claims
Tax already paid and payment references
Prior-period returns and HMRC correspondence

Accounts also outstanding?

We can scope the statutory accounts and CT600 together so the figures reconcile and both filing obligations are addressed.

QUESTIONS

Before you enquire.

Are Corporation Tax payment and CT600 filing deadlines the same?+

Not necessarily. The payment date and return filing date can differ, so we check both dates for the accounting period.

Can you file a CT600 urgently?+

Potentially, if the accounts and supporting tax information are complete and the engagement can be accepted in time.

Can you deal with HMRC for us?+

We can arrange the appropriate authorisation and deal with agreed Corporation Tax matters within the engagement scope.
