When is Corporation Tax due?
For most companies, nine months and one day after the end of the accounting period. The CT600 return itself is due twelve months after the period end, so payment is usually due before the return.
Corporation Tax
Corporation Tax, calculated correctly and planned for.
We take care of your Corporation Tax calculations and returns, making sure your business meets HMRC requirements while identifying legitimate opportunities to improve tax efficiency. We also help you plan ahead for upcoming tax liabilities, so there are fewer surprises and you have a clearer idea of what your business needs to set aside.
- Calculated correctly. The computation agrees with your accounts, not a version of them.
- Known in advance. An estimate during the year so the money is set aside, not found.
- Filed and defended. CT600 submitted, HMRC letters handled for you.

In practice
Fewer surprises at the year end.
Corporation Tax is charged on your company's profits, but the taxable figure is rarely the same as the profit in your accounts. Allowable expenses, capital allowances and reliefs all change the position.
We prepare the computation alongside your annual accounts, so the two agree and the return reflects what the business actually did.
- Corporation Tax computations prepared and the CT600 filed with HMRC.
- Capital allowances reviewed, including full expensing and the annual investment allowance.
- Allowable and disallowable expenditure identified and documented.
- Losses, reliefs and prior-year adjustments applied where they are available.
Planning
Know what is due, and when, before it lands.
Corporation Tax is usually payable nine months and one day after the end of the accounting period, which can arrive quickly if nobody has been keeping an eye on it.
We give you an estimate during the year rather than after it, so the money can be set aside instead of found.
- An indication of the likely bill before the year end, not after.
- Payment dates set out clearly, including quarterly instalments if you reach that threshold.
- Timing of purchases, salary and dividends considered in the round.
- HMRC correspondence handled on your behalf.

Frequently asked questions
Corporation Tax questions we hear most.
What is the current Corporation Tax rate?
The rate depends on your level of profits, with a small profits rate, a main rate and marginal relief in between. We apply the correct rate for your company and show the effect in the computation.
Can I reduce my Corporation Tax bill?
There are legitimate ways to improve efficiency, including capital allowances, pension contributions and how you take income from the company. We look at these as part of your year, not as an afterthought.
