R&D or just BAU? A 10-minute self-check for your business
Not sure if your project qualifies for R&D tax relief? Our 10-minute self-check and mini worksheet help you spot the difference between BAU and genuine R&D.
For many businesses, distinguishing between business-as-usual (BAU) improvements and eligible Research & Development (R&D) can be tricky.
Getting it right matters: qualifying R&D can unlock valuable tax relief, but only if your work meets HMRC criteria.
This guide walks you through a quick, practical self-check you can complete in under 10 minutes to help identify qualifying projects and start capturing evidence efficiently.
Understanding R&D eligibility
R&D work typically involves:
- Baseline: What was already known or available before your project, and why it wasn’t enough.
- Technological/Scientific Uncertainty: Challenges that cannot be solved using routine methods.
- Sought Advance: Measurable improvements in capability, performance, reliability, or integration, not just cosmetic or commercial tweaks.
- Systematic Work: A planned, iterative programme of tests, prototypes, or analysis rather than ad hoc tinkering.
The 5-question self-check
Answer Yes/No to each. Treat “not sure” as No for now.
- Baseline: Can you demonstrate the starting point and its limitations?
- Uncertainty: Did your project involve technical or scientific challenges beyond standard practice?
- Advance: Were you aiming for measurable progress, not just minor improvements?
- Systematic Work: Did you follow a structured programme of testing and iteration?
- Traceability: Can you reasonably track time and costs to qualifying work?
Interpreting the results
- 4–5 Yes: Strong chance of qualifying R&D. Capture evidence now.
- 2–3 Yes: Grey area, tighten framing and start light evidence tracking.
- 0–1 Yes: Likely BAU, but keep notes; work may evolve into qualifying R&D.
Mini worksheet (one page)
Use a single page to organise:
- Project name & goal
- Baseline evidence & uncertainties
- Planned tests or iterations
- Success criteria & people involved (rough % time)
- Costs (staff, tools, prototypes)
- Date range & current status
Think of this as a signpost for your claim, not a detailed thesis.
Common grey areas
- Performance tuning vs R&D: Routine tweaks = BAU. Extending capabilities = potential R&D.
- Integration work: Standard integration = BAU. Novel interoperability = potential R&D.
- No failures? That’s fine. Uncertainty at the start and a systematic approach are what count.
Evidence that stands up
HMRC wants clarity on:
- The nature of the uncertainty
- How it was investigated
- The methods and measurements used
Proprietary details don’t need to be shared, just clear documentation of the process.
Quick 20-minute weekly routine
Capture evidence efficiently:
- Meeting note (5 min): Who did what and why it mattered
- Experiment log (10 min): Prototype/test → observation → next step
- Time snapshot (5 min): Approximate % of week spent on qualifying work
A small routine now saves major effort and reduces risk at year-end.
