Business Tax

Corporation tax planning that goes beyond the annual computation — from R&D relief and capital allowances to profit extraction and group structures.

The service

Compliance is the floor. Planning is the ceiling.

Every limited company client gets a review of the previous 12 months before we finalise the CT600 — not just to spot missed reliefs, but to shape decisions in the year ahead. Salary and dividend mix, timing of capital purchases, use of the annual investment allowance, R&D eligibility: the return is where we close the year, but the value we add lives in the conversations before it.

  • Corporation tax returns (CT600)
  • R&D tax relief claims
  • Capital allowances & annual investment allowance
  • Director remuneration planning
  • Group and holding company structures
  • Enterprise Investment Scheme (EIS) & SEIS advance assurance
  • Employment-related securities returns (ERS)

R&D tax relief — done properly

Engineer working on prototype

The R&D relief regime has tightened significantly since 2023. We only prepare claims we would be comfortable defending in an HMRC enquiry — which means detailed technical narratives, a documented cost analysis, and a genuine assessment of whether the work meets the BEIS definition of R&D.

If you have been approached by a "no-win no-fee" R&D boutique, we would encourage you to get a second opinion before signing. Overstated claims are the single biggest driver of HMRC enquiries our clients face.

  • Free eligibility review
  • Technical narrative drafted in-house
  • Additional Information Form & CT600L filed for you
  • Fixed fee — no percentage of the claim
FAQ

Common questions

What is the current corporation tax rate?

For accounting periods ending after 1 April 2023, the main rate is 25% with a small profits rate of 19% for profits under £50,000 and marginal relief between £50,000 and £250,000. We model the effective rate against your forecast profits at each year-end review.

Should I take salary or dividends?

For most owner-managers we recommend a salary up to the NIC secondary threshold, with the balance as dividends. The optimum mix depends on your other income, pension contributions and whether the company qualifies for the Employment Allowance — we run the numbers as part of every annual review.

Do you handle CT61 & loan-to-participator (s.455) charges?

Yes. Director's loan account monitoring is part of every limited company engagement, and s.455 charges are computed as part of the CT600 workflow.
