About Bonham and Brook
Bonham and Brook is a fast-growing advisory firm specialising in optimising tax relief solutions for businesses. We’re building our UK team in London, and while our services are specialist, our reputation comes from high performance, strong values and a culture that backs our people to succeed.
The Role
We're looking for an experienced, ATT-qualified Senior Financial Consultant to join our R&D tax consultancy team.
You'll take ownership of R&D tax engagements, working directly with clients to analyse financial information, identify qualifying expenditure and prepare accurate, well-supported claims.
We're particularly interested in someone who combines hands-on R&D tax experience with practical corporation tax knowledge, including preparing CT600 returns and understanding how R&D relief is reflected in corporation tax computations.
Key Responsibilities
R&D financial analysis: Review trial balances, general ledgers, payroll and other financial records to identify and substantiate qualifying R&D expenditure.
Claim preparation: Prepare and review R&D cost calculations, financial assessments and supporting working papers.
Corporation tax: Prepare or review relevant corporation tax computations and CT600 returns, ensuring R&D claims are correctly reflected.
Client advisory: Lead financial discussions, challenge assumptions and provide clear, practical advice on R&D expenditure and tax treatment.
Engagement ownership: Manage a portfolio of R&D claims, coordinate with Technical Consultants and drive work through to filing.
Quality and development: Maintain high standards of accuracy and compliance, support junior colleagues and contribute to improving our delivery processes.
Qualifications and Experience
We are seeking a technical professional who possesses:
An ATT qualification.
Proven experience preparing UK R&D tax relief claims.
Practical experience preparing CT600 corporation tax returns and supporting tax computations.
Strong Excel skills and confidence analysing detailed financial information.
A sound understanding of UK corporation tax and R&D tax relief legislation.
Confidence managing client relationships and multiple engagements.
Strong analytical judgement, organisation and attention to detail.
CTA qualification or progress towards CTA would be advantageous, as would experience reviewing the work of junior consultants.
Why Join Us?
You'll have the opportunity to take ownership of client engagements, work with a varied portfolio of businesses and help shape how our R&D consultancy develops.
We're looking for someone who combines technical competence with commercial judgement, takes responsibility for delivering high-quality work and wants to contribute to a growing consultancy team.
