Corporation Tax made simple
Every limited company must calculate its taxable profit, file a Company Tax Return (CT600) and pay any Corporation Tax due on time. We prepare your tax computation alongside your annual accounts, claim the allowances and reliefs your company is entitled to, and file the return with HMRC.
We also look ahead. Before your year end we review your expected profit so you know roughly what will be due and when — and whether there are legitimate steps, such as timing capital investment or pension contributions, that could reduce the bill.
What's included
- Corporation Tax computation
- CT600 Company Tax Return filed with HMRC
- Capital allowances, including Annual Investment Allowance
- Review of reliefs such as R&D where relevant
- Corporation Tax payment reminders and estimates
- Handling HMRC correspondence and enquiries
Who it's for
Limited companies of all sizes, contractors' personal service companies and property investment companies. We regularly help contractors & freelancers, small businesses & limited companies.

Corporation Tax FAQs
When is Corporation Tax due?
For most small companies, Corporation Tax must be paid 9 months and 1 day after the end of the accounting period. The CT600 return is due 12 months after the period end.
Is Corporation Tax the same as filing accounts at Companies House?
No. Annual accounts go to Companies House, while the Company Tax Return and tax payment go to HMRC. They're separate obligations with different deadlines, though we prepare them together.
Can I reduce my company's Corporation Tax?
Legitimately, yes — by claiming all allowable expenses and capital allowances, considering employer pension contributions and timing investment sensibly. We'll review the options before your year end.
