What We Handle
Corporation tax is more than filing a form. The CT600 must reflect the correct accounting treatment, the right capital allowances, any research and development credits, loss relief elections and — if applicable — the associated payment plan. Getting any of these wrong costs money.
Corporation Tax Returns (CT600)
We prepare and file your CT600 with HMRC, including all supplementary pages for losses, group relief, R&D credits, chargeable gains and controlled foreign companies where applicable. Your tax computation is prepared from your statutory accounts — not estimated.
Self-Assessment (Personal Tax)
Director dividends, salary, rental income, capital gains from share disposals — we prepare personal self-assessment returns for owner-directors so that your company and personal tax positions are coordinated and efficient.
Tax Planning
Before we file, we review your position. Are you claiming all available capital allowances? Have you utilised brought-forward losses? Is your salary/dividend mix optimal? These questions are not afterthoughts — they are part of the engagement.
HMRC Correspondence
If HMRC writes to you, we handle it. Enquiry notices, information requests, penalty appeals — all dealt with by a Chartered Accountant, not a call centre.
Key Deadlines You Cannot Miss
9 months after year-end
Corporation tax is due for payment. Interest accrues from this date if unpaid.
12 months after year-end
CT600 must be filed with HMRC. Automatic £100 penalty applies immediately after this date.
31 January each year
Self-assessment filing and payment deadline for owner-directors.
9 months & 1 day after year-end
Statutory accounts must be filed at Companies House for private companies.
Missing deadlines costs real money.
HMRC’s automatic late filing penalty is £100 rising to £200 after 3 months, then 10% of the unpaid tax after 6 months. On top of this, interest on unpaid tax currently runs at the Bank of England base rate plus 2.5%.
