For many innovative SMEs in the UK, R&D tax credits are an important funding source. The landscape has seen significant change, with new schemes and increased oversight shaping R&D tax credit claims. Understanding and keeping up with these changing rules is more important than ever.
Despite new R&D tax credit restrictions, these incentives remain highly beneficial. The UK government plans to invest £20.4 billion for R&D investment in 2025-26, showing strong support for innovation.
It is important to understand the new R&D SME scheme and meet the stricter compliance standards. Careful preparation and robust documentation are essential. This guide will help your SME unlock the full potential of these generous reliefs.
What Qualifies as R&D Tax Credit?
To claim R&D tax credits successfully, SMEs must first get an understanding of what activities are truly qualified as R&D for tax purposes.
The goal is not just simple improvement but to make a genuine scientific or technological progress by solving a specific problem.
Important elements
Advance in science or technology: The project must improve knowledge or capability. This improvement must be within a recognised scientific or technological field.
Technical uncertainty: There must be genuine uncertainty present. This uncertainty cannot be readily resolved by existing knowledge.
Systematic investigation: The work must follow a structured approach. This approach must focus on resolving the uncertainty identified.
Common misunderstandings
Simply making something “better” doesn’t automatically qualify for R&D tax credit. The advance must be within science or technology, not business processes.
Industry-specific improvements may not constitute scientific advances. The baseline is the current “state-of-the-art” in relevant fields.

The New Scheme Structure
For accounting periods starting on or after April 1, 2024, SME R&D tax relief rules have changed. The old schemes have been brought together into one main approach.
Companies that spend a large share of their resources on R&D may still qualify for extra support.
1. Merged R&D Scheme (RDEC)
Applicable: All companies from accounting periods beginning April 1, 2024
| Feature | Details |
|---|---|
| Credit Rate | 20% on qualifying R&D expenditure |
| Net Cash Benefit | Approximately 16.2% after tax |
| Credit Type | Above-the-line credit (appears in profit & loss) |
| Refundability | Refundable as cash regardless of tax position |
Major Changes:
Contracted-out R&D: Significant restrictions on claiming for work contracted to/from other parties. Enhanced documentation requirements apply to all contracted work.
Overseas R&D: Generally no longer qualifies for relief claims. Limited exceptions exist for specific circumstances only.
Enhanced Documentation: Increased emphasis on supporting evidence throughout the claim process. Contemporary records become essential for all activities.
2. R&D Intensive Scheme (IRIS)
The Enhanced R&D Intensive Support (ERIS) scheme, often referred to as IRIS, provides crucial support for SMEs that are highly innovative.
Eligibility: SMEs spending 30% from 2024 of total expenditure on R&D.
Benefits: Enhanced relief rates compared to merged scheme available. Continuation of SME-style enhanced deductions for qualifying companies.
Surrenderable losses for cash credits remain available. This provides significant cash flow benefits for loss-making companies.
Limitations: Complex qualification criteria affect many potential claimants. Difficulty exists for companies with overseas operations.
Aggregates total group expenditure including linked enterprises. Requires UK R&D expenditure as numerator versus global expenditure.
3. Pre-notification Requirements
Critical New Obligation: Companies must notify HMRC before making R&D claims. This represents a fundamental change in claiming procedures.
Timeline: Within 6 months of accounting period end for all new claimants.
Exemptions: Companies with claims in the last 3 years may be exempt. However, claims made via amended returns may not count.
March year-end companies are particularly affected by these changes. Failure to pre-notify results in automatic claim rejection.

Compliance and Scrutiny Environment
The rules around SME R&D tax credits have clearly changed. HMRC is now more cautious and less hands-on, carrying out more compliance checks and using random selection in its review process.
Businesses need to be well-prepared, with strong documentation to support their claims.
The New Reality
20% of R&D claims are now subject to compliance checks. HMRC has adopted a more sceptical, less collaborative approach.
Volume-based compliance strategy includes some random selection elements. Enhanced focus on “competent professional” requirements affects all claims.
Key Compliance Focus Areas
1. Competent Professional Requirements
Technical leader with relevant qualifications and experience required. Ability to distinguish between R&D and routine development essential.
Must understand current state-of-the-art in relevant field clearly. Increasing emphasis on documenting their competence throughout projects.
2. Record Keeping Excellence
Contemporary documentation of R&D activities becomes mandatory. Clear identification of advances sought and uncertainties faced required.
Detailed cost tracking and allocation systems essential. Project-by-project documentation of technical challenges must be maintained.
3. Qualifying Expenditure Documentation
Robust systems for identifying and tracking R&D costs required. Clear allocation methodologies must be documented thoroughly.
Supporting evidence for all claimed expenditure is essential. Compliance with territorial restrictions affects all overseas activities.

| Cost Type | Qualifying Criteria |
|---|---|

Developing innovative user interfaces with technical complexity qualifies. Routine bug fixes or minor updates don’t qualify.
Standard business process improvements aren’t eligible for relief. Activities without technical uncertainty don’t qualify.
Small Business R&D Tax Credits: Special Considerations
Small and Medium-sized Enterprises (SMEs) have their own set of rules when it comes to R&D tax credits especially with the new Enhanced R&D Intensive Support (ERIS). Understanding how it works can help SMEs make the most out of what is available.
SME Definition and Thresholds
Small and medium enterprises must meet specific criteria. Fewer than 500 staff and turnover under €100m qualify.
Balance sheet total under €86m also qualifies businesses. These thresholds determine which relief scheme applies.
Enhanced Rates for SMEs
R&D intensive SMEs receive enhanced relief rates. 30% of total expenditure on R&D triggers higher rates.
This provides significant advantages over standard schemes. Cash flow benefits particularly help growing businesses.
Startup Considerations
Pre-revenue companies can claim significant cash refunds. Credits are available regardless of tax position.
Loss-making companies receive direct cash payments. This makes R&D relief valuable for innovative startups.
Common R&D Tax Credit Mistakes SMEs Make
SMEs often make mistakes with R&D tax credits that can risk their claims or trigger HMRC checks. Avoiding these is key to getting approved.
Documentation Failures
Many companies fail to maintain adequate contemporary records. This creates significant compliance check vulnerabilities.
Inadequate technical documentation remains the primary rejection reason. Companies must clearly articulate advances sought.
Misunderstanding Qualifying Activities
Simply improving business processes doesn’t qualify automatically. The advance must be within science or technology.
Industry-specific improvements may not constitute scientific advances. The baseline is current “state-of-the-art” standards.
Cost Allocation Errors
Poor cost allocation evidence frequently triggers compliance issues. Companies must demonstrate clear methodologies.
Robust systems for tracking costs are essential. All claimed expenditure requires supporting evidence.
Overseas R&D Claims
Generally no longer qualifies from April 2024. Limited exceptions exist for specific circumstances only.
Companies with overseas operations must review restrictions carefully. Territorial planning becomes essential for claims.
What are the HMRC guidelines on R&D?
HMRC has become more active in reviewing R&D tax claims, and SMEs need to be ready. Knowing what HMRC looks for and how to respond when questioned can make all the difference in protecting your incentive and reputation.
If Selected for Review
Initial Response Strategy: Don’t panic as many checks resolve successfully. Gather all supporting documentation immediately.
Involve your competent professional early in the process. Consider specialist advisor support for complex cases.
Key Success Factors: Provide comprehensive, well-organised evidence to HMRC. Clearly articulate scientific or technological advances.
Document uncertainties and resolution approaches taken. Demonstrate systematic investigation methodology throughout.
Escalation Options

Mistakes to avoid
Inadequate technical documentation triggers immediate concerns. Unclear competent professional identification causes problems.
Poor cost allocation evidence frequently leads to rejections. Routine development claimed as R&D fails scrutiny.
Overseas costs without valid exemptions are rejected. These represent the most common compliance failures.
