In our previous discussion, we covered the UK’s R&D Tax Relief scheme, the eligibility criteria for businesses to claim, the changes to claim calculations and compliance rules introduced in April 2024, and what qualifies as eligible R&D activity, including the reasons why many founders choose to self-exclude.
Now, let’s explore how businesses like yours can maximise the value of their claims, identify eligible expenses, and take practical steps to adapt to HMRC’s compliance requirements.
How can businesses maximise their claim value and identify all eligible expenses?
Maximising an R&D tax claim starts with one discipline: keeping good records throughout the year, not attempting to reconstruct them at filing time.
Strong claims are built on evidence:
- Project notes
- Timesheets or other effort recording system
- Technical discussions records
- Prototype logs
- Failed tests
- Clear documentation of who worked on what and when
The businesses that consistently secure the strongest returns are those that treat record-keeping as an ongoing process, not an annual scramble.
Understanding what costs can be included is equally important, because claims are frequently undervalued simply due to missed qualifying expenses. Eligible costs can include:
- Staff time
- Subcontractors
- Software licenses
- Consumables
- Certain externally provided worker costs
- Clinical trials
Of these, staff time is typically the largest component, though not always, and should never be estimated loosely. A well-evidenced breakdown of how much time each team member spent on qualifying activity can materially increase the final value of a claim if not the compliant nature of the tax relief claim.
Working with an R&D specialist rather than a generalist accountant has also become increasingly important with the various changes in the R&D schemes and HMRC scrutiny intensifying.
A specialist will rely on the facts of each project to assist the company in narrating qualifying activities to HMRC in line with the DSIT Guidance and aid the company in identifying costs that a non-specialist would routinely miss. The difference in claim value and robustness can be substantial.
The best claims are not simply compliant, through being carefully documented, but are prepared with both the with the final claim submission in mind from the very start but with the intellectual property development, protection and exploitation in mind This is possible for both forward-thinking businesses with systems already in place to capture the R&D details and companies in need of a retrospective assessment of their R&D.
What practical steps should businesses take to adapt to HMRC’s tougher compliance regime?
HMRC’s direction is clear: more scrutiny, tighter compliance, and a higher bar for what constitutes an acceptable claim. But for businesses that prepare properly, this shift is an advantage, not a barrier.
The companies best placed in future claim cycles will be those that have already embedded R&D evidence into their everyday operations, not those scrambling to piece together a narrative at year-end.
The practical steps are straightforward. Map your qualifying projects now. Identify the staff involved, document the technical uncertainties as they arise, and review your internal processes before year-end to close any gaps in cost capture or project records. Most companies already have existing processes to bolt on this tweak.
The direction is stricter, but it is not less rewarding. Businesses that plan ahead, document sufficiently, and understand the rules will be best positioned to claim confidently, compliantly, and with maximum value.
What is the most important takeaway for claiming successfully?
If there is one takeaway from everything above, it is that the opportunity is real, but it rewards those who prepare. So, we highly advise starting to track R&D activity throughout the year, not just at filing time; review which costs may qualify; do not self-exclude; document everything and most importantly, work with a specialist like InnoFund to avoid claiming incorrectly and to submit more compliant claim to HMRC.
During these tough economic times, leave no money on the table!
