R&D tax in practice: structure, support & opportunity

The R&D tax landscape has changed significantly over the past year.

As firms navigate the merged scheme, overseas restrictions and new administrative requirements, attention increasingly turns toward how R&D claims are delivered in practice.

Strong technical expertise remains essential. What has become equally important is the structure surrounding how that expertise is applied, ensuring claims are consistent, well-documented and able to withstand scrutiny.​​

Despite the increased complexity, R&D tax relief remains an important area of support for innovative companies, and a valuable advisory service for firms that can deliver it well.

In response, many firms are placing greater emphasis on how R&D claims are prepared in practice…

The changed landscape…

These changes are reflected across several key areas of the R&D tax scheme.

The following highlights where the most notable updates have occurred, and how they affect the preparation of claims in practice:

The merged scheme

The introduction of the merged RDEC scheme has brought together elements of the previous SME and RDEC regimes, changing how claims are calculated and presented. While this has simplified certain structural differences between schemes, it has also introduced new considerations around eligibility intensity and transitional claims, particularly for companies with accounting periods spanning the change.

Overseas restrictions

Under the merged scheme, restrictions on overseas expenditure now apply to subcontracted R&D and externally provided workers, with only limited exemptions. While the rules are clearly defined in legislation, applying them in practice often requires careful assessment of where activities are carried out, and how costs are structured and evidenced.

Subcontracting rules

Changes to subcontracting rules have shifted the focus toward understanding who initiated the R&D, and whether R&D was anticipated at the outset of a contract. This has introduced a more nuanced approach to determining which entity can claim, requiring clear documentation and consistent application across different client scenarios.

Reporting requirements

The introduction of the Additional Information Form (AIF) has increased the level of detail required when submitting R&D claims. Firms are now expected to provide more granular information on projects, costs and methodologies, reinforcing the need for structured information gathering and clear documentation throughout the claim preparation process.

Claim notification

Pre-notification requirements through the Claim Notification Form (CNF) have introduced an additional step in the claims process for certain companies. Missing a notification deadline can prevent a claim from being made, placing greater emphasis on identifying potential R&D activity early and maintaining appropriate internal processes.

Taken together, these changes increase the operational expectations placed on firms preparing claims.

Why structure and support matter now more than ever

Navigating the transition period

Firms preparing R&D claims are currently operating across multiple regimes.

Operating confidently across these frameworks requires more than technical understanding – it requires processes that support consistent and well-documented decision-making.
