Self assessment, corporation tax, and CGT, the paperwork side handled.
Preparation support for SA100 self-assessment, Account/CT600 corporation tax, and capital gains returns — the data-gathering and drafting side, so your accountants focus on the advisory judgement calls.
Three return types, three different rhythms
Personal, company, and gains-related filings each have their own data and deadlines — tracked and prepared to the point your accountant just reviews and signs off.
SA100 self-assessment prep
Personal tax return data gathered and drafted ahead of the 31 January deadline, for directors, sole traders, and individuals with more complex income.
Account/CT600 corporation tax prep
Company tax return data prepared from the accounts, ready for your accountant's review before submission to HMRC.
CGT calculations and 60-day reporting
Gains on property and other assets calculated, with the 60-day UK property CGT return prepared and tracked against its own separate deadline.
Supporting schedules chased
Bank interest, dividend vouchers, P60s, and disposal records requested and chased from clients well ahead of deadline.
The judgement call stays with your accountant
Preparing a return and signing it off are two different skills — one is data-gathering and drafting, the other is professional judgement. We handle the first so your qualified staff spend their time on the second.
Three steps to a return ready for sign-off
Built around each return's own deadline, not a single one-size-fits-all timeline.
Data and documents chased
Supporting records requested from clients against a schedule that gives your accountant time to review before the deadline.
Return prepared
SA100, Account/CT600, or CGT calculations drafted in your existing software, ready for your accountant's sign-off.
Reviewed and filed
Your accountant reviews and approves, then the return is submitted and the outcome logged.
What is SA100 used for, and is it the same as a tax return?
SA100 is the main Self Assessment tax return form for individuals — it's what most people mean by "doing a tax return." It covers personal income, including from self-employment, property, and dividends.
Who needs to file a Account/CT600?
Every limited company registered with Companies House must file a Account/CT600 Company Tax Return with HMRC, reporting profits and calculating Corporation Tax due, even if the company made a loss.
What's the difference between SA100 and Account/CT600?
SA100 is filed by an individual for their personal tax position, while Account/CT600 is filed by a company for its own Corporation Tax — a director typically needs both filed separately, one for themselves and one for the company.
When do I need to report Capital Gains Tax in the UK?
Gains on UK residential property must be reported and paid within 60 days of completion. Other gains above the annual exempt amount are reported through Self Assessment, with tax normally due by 31 January after the tax year ends.
