Corporation tax — handled, planned, never a surprise.
CT computations, CT600 filing, and the planning conversations that happen before windows close.
Most clients meet their corporation tax bill the same day it's due. We discuss it monthly through the Portfolio Reporting Pack — so by year end, the bill is forecastable, payable, and never unexpected.

Corporation tax — handled, planned, never a surprise — common questions.
When is corporation tax due?
For most UK limited companies, corporation tax is due 9 months and 1 day after the end of the accounting period. The CT600 return must be filed within 12 months of year end. Larger companies (taxable profits over £1.5m) pay quarterly instalments.
What is the corporation tax rate?
From April 2023, the UK corporation tax rate is 25% for companies with profits over £250,000, with a small profits rate of 19% for profits under £50,000 and marginal relief between those bands. Rates can change in Budget announcements — we apply current rates for your specific period.
Can you claim R&D tax credits for me?
Yes — for qualifying R&D activity. We identify R&D potential annually, prepare the technical narrative and cost computation, and submit the claim with the CT600. HMRC has tightened its R&D scrutiny significantly; we only claim where the activity genuinely qualifies and the evidence is robust.
How is my salary and dividend mix optimised?
Annually, we review your director's salary (typically set at the NI primary threshold), dividend extraction within basic-rate band, and whether pension contributions could reduce your company's CT liability. Reviewed in writing at the Annual Compliance Review.
What if I'm a sole director with payment on account due?
If your CT bill exceeds £10,000 and you haven't paid it before, HMRC may put you on quarterly instalments going forward. We forecast this and prepare the cash position so it doesn't trigger a working-capital crisis.
