UK / ANNUAL ACCOUNTS & CORPORATION TAX

Annual Accounts and Corporation Tax Support for UK Companies

Bring together the accounts and tax workings your limited company needs at year-end. TaxSpex can prepare year-end accounts, Corporation Tax computations and a CT600 for review, with supporting schedules and queries agreed as part of the work. Companies House accounts and the HMRC Company Tax Return are separate filings, with different requirements and deadlines.

What the year-end service can include

  • Year-end accounts preparation from the company’s financial records
  • Corporation Tax computations and CT600 preparation
  • Supporting schedules and review queries
  • Filing support where the service is agreed and the relevant access and authorisation requirements are met

We confirm the entity, accounting period, records available and filing responsibilities before work begins.

Who this service is for

This service is intended for UK limited companies preparing for their financial year-end and Corporation Tax obligations. If the company has incomplete bookkeeping, unusual transactions, overseas activity, group relationships, historic errors or a change in its circumstances, tell us before we quote. Those matters may change the work required and must be assessed individually.

How the work proceeds

  1. 1
    Confirm the period and records

    We agree the accounting period, records available, expected deliverables, review process and any filing support.

  2. 2
    Prepare accounts and tax workings

    We prepare the agreed accounts, computations, CT600 and supporting schedules, then raise review queries where information is missing or needs clarification.

  3. 3
    Review and approve

    The directors review and approve the accounts and tax return. Filing support is provided only where agreed and authorised. Directors remain responsible for company records, approvals and submissions.

Filing responsibilities and deadlines

Companies House annual accounts and the HMRC Company Tax Return are separate filings. For many private companies, Companies House accounts are due nine months after the financial year end; Corporation Tax is generally payable nine months and one day after the end of the accounting period; and a Company Tax Return is generally due 12 months after the end of that period. First accounts, shortened periods and other circumstances can change the timetable. Confirm your company’s dates with HMRC and Companies House.

TaxSpex does not provide audit or assurance under this service. A statutory audit, where required, is outside scope.
