Overview
Corporation Tax (CT600)
Corporation tax filing requires more than entering a profit figure. This service supports CT600 preparation with cleaner records, tax computations, allowable expense review and filing-ready documentation.
Corporation Tax CT600 services for UK limited companies needing tax computations, records review, HMRC filing support and compliance clarity.
Primary outcome
Clear computation trail, reviewed records and filing-ready CT600 support.
Problem fit
Where this service earns its keep
CT600 preparation becomes fragile when final accounts, supporting schedules and tax-sensitive transactions are incomplete or when nobody owns the questions that bridge accounting profit to the tax computation.
Friction
Year-end records are not ready for tax review
Open reconciliations, missing schedules and unresolved accounting entries can delay the computation and make material tax adjustments harder to support.
Friction
Accounting and tax treatments are conflated
A cost recorded in the accounts does not automatically determine its Corporation Tax treatment, so unsupported assumptions can enter the return if adjustments are not reviewed.
Friction
Relief claims lack an evidence owner
Potential allowances or reliefs may be discussed without a complete factual record, an accountable company contact or clarity about whether specialist advice is required.
Friction
The filing and payment timetable is unclear
Directors can miss decision points when accounts finalisation, return approval, submission responsibilities and payment planning are treated as one undifferentiated deadline.
Friction
Questions surface too close to submission
Late access to prior returns, company changes or supporting evidence leaves limited time for the company to resolve queries and approve the final position.
What you gain
A clearer computation trail and filing decision
The service organises the records, adjustments, material assumptions and company approvals needed for the agreed Corporation Tax work, while keeping specialist matters and unresolved positions visible.
Outcome
A defined records request
The company receives a focused list of final accounts, supporting schedules, prior-return information and transaction evidence needed for the agreed period.
Outcome
Adjustments linked to supporting evidence
Material movements from accounting profit to the tax computation are documented against the records and assumptions available for review.
Outcome
Uncertain positions raised before approval
Missing support, unusual transactions and matters requiring specialist advice are identified for a company decision instead of being buried in the final calculation.
Outcome
Responsibilities separated across the timetable
Accounts readiness, query resolution, return approval, any agreed submission activity and payment responsibility are made visible as distinct steps.
Outcome
A reusable period filing pack
The agreed computation, supporting schedules, approvals and submission evidence are organised so the company can retrieve the basis of the filing later.

Best fit
This is a strong fit when
UK limited companies preparing their Corporation Tax position after the annual accounts are finalised.
Owner-managed businesses that want material tax adjustments and assumptions documented for director review.
Companies coordinating bookkeeping, accounts preparation and CT600 responsibilities across different providers.
Directors able to supply complete records, answer queries and approve the return within the agreed timetable.
Not the right fit
Pause before booking when
Companies asking for submission before final accounts and supporting records are sufficiently complete.
Requests to hide transactions or include a relief or adjustment without adequate factual support.
Complex international, group, restructuring or specialist-claim matters assumed to be included without separate scoping.
Directors unwilling to review and authorise the company's tax position.
How it works
How the CT600 position is prepared and reviewed
The route starts with final accounting information, follows the material tax adjustments and ends with documented company approval and the submission responsibility named in the written scope.
Step 1
Confirm the company and period evidence
We review the final accounts, supporting schedules, prior-return context, company details and known transactions that may affect the agreed Corporation Tax work.
Step 2
Prepare the computation and resolve queries
Accounting profit is reconciled to the draft tax position, material adjustments are documented and missing support or specialist questions are returned to the company.
Step 3
Complete approval and the agreed filing step
The company reviews the computation and material assumptions, authorises the return where applicable and receives the agreed filing pack and payment-timetable information.
Pricing
CT600 support scoped by records, complexity and readiness.
Pricing depends on account quality, transaction complexity, adjustments required and the level of tax preparation support needed.
From £450 + VAT
Straightforward CT600 work starts from this level. Complex accounts, adjustments, director loans, losses, groups or late records are quoted after review.
What is included
Straightforward corporation tax return support where records are clean and ready.
Scoped separately
Accounts preparation, complex tax adjustments, late records, groups, R&D, losses and advisory are scoped separately.
Questions
CT600 preparation, submission and specialist boundaries
The answers below clarify what the company must provide, how filing responsibility is confirmed and why reliefs, groups, overseas activity and enquiries may require separate expertise.
Will you prepare the CT600, submit it, or both?
The written scope states whether the engagement covers preparation only or also an authorised submission step. Submission cannot proceed until the required accounts, computation, company approval and agent arrangements are in place.
What records are needed to prepare the Corporation Tax computation?
The starting point normally includes final accounts, supporting schedules, prior-return information, company details and evidence for material transactions or adjustments. The precise request depends on the company and accounting period.
Will you identify every relief the company can claim?
Potential reliefs can be considered where relevant facts and evidence are available, but eligibility is not assumed. Specialist relief work may need separate advice and a separately agreed scope.
Can the service cover group companies or overseas activity?
Those matters must be identified during scoping. The entities, residence, transactions and technical questions determine whether the work can be included or requires specialist tax support.
Does the filing fee include handling a later HMRC enquiry?
No enquiry support is assumed. If correspondence or an enquiry arises, the facts, authority, records and expertise required are reviewed before any separate work is agreed.
