£96,000 back for solving problems no one had solved.
How a software company's platform rebuild qualified as R&D and produced a six-figure expenditure credit.
- £480,000
- Qualifying R&D expenditure
- £96,000
- Expenditure credit (20%)
- c. £72,000
- Net after Corporation Tax
The engagement
The company spent the year rebuilding its platform's core: a real-time processing engine that had to handle a tenfold increase in throughput without a tenfold increase in infrastructure cost. No published pattern fitted. The team prototyped, discarded and re-architected their way to a solution. To their accountants it looked like payroll.
Our approach
- Scoping call with the CTO to map the year's projects
- Short structured interviews with lead engineers
- Payroll, cloud and subcontractor costs apportioned to qualifying work
- Technical report and Additional Information Form delivered for the CT600
The result
- Staff costs (qualifying proportion)
- £372,000
- Qualifying subcontracted development
- £62,000
- Cloud computing & data costs
- £46,000
- Total qualifying R&D expenditure
- £480,000
How the credit is calculated
£480,000 × 20% = £96,000
Above the line, visible to the board and investors, and payable in cash where it exceeds the tax bill.

The work was already done and already paid for. The claim just made sure the company recognised it as R&D.
