CT600 accountant and Company Tax Return filing

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

A CT600 is more than a form

The Company Tax Return is supported by statutory accounts and a tax computation. We reconcile those documents before filing so the reported profit, adjustments, reliefs and tax position form one coherent submission.

What to send first

A concise opening pack lets us assess both feasibility and timing.

Company name, number and accounting period
HMRC notice and CT600 deadline
Final or draft statutory accounts
Trial balance and supporting schedules
Prior CT600 and tax computation
Corporation Tax payments and HMRC correspondence

When the deadline is close or has passed

We separate the filing obligation, payment position and any penalty correspondence. Where the file is complete and acceptance checks can be finished, suitable work can enter the priority queue.

Accounts not finished?

We can scope the statutory accounts and CT600 together. If the underlying records need clean-up, we explain that dependency before promising a filing timetable.

QUESTIONS

Before you enquire.

Can you file only the CT600?+

Potentially, if reliable final accounts and the supporting tax information are available. We still review the accounts-to-tax reconciliation before accepting the filing.

Can you prepare an overdue CT600?+

Yes. We first identify every outstanding period, related accounts, payments and HMRC notices, then agree the recovery scope.

Is Corporation Tax due on the same date as the CT600?+

Often not. Payment is generally due before the Company Tax Return, so both dates and any interest position should be checked separately.
