Working with Accountants: A Structured Approach to Tax Relief
Quick Answer
Lexmore works alongside accountancy firms to support clients with R&D Tax Relief, Patent Box and Embedded Capital Allowances, providing specialist input where required.
Introduction
For most UK businesses, the relationship with their accountant sits at the centre of financial decision-making.
Accountants provide ongoing support across compliance, reporting and tax planning. However, certain areas of tax relief, particularly those involving technical or sector-specific knowledge, can require additional specialist input.
Working alongside a specialist adviser through our accountancy partnership programme can help ensure that opportunities are identified and claims are prepared in a structured and compliant way, without disrupting the existing client relationship.
1. Where Specialist Input Adds Value
Some areas of tax relief require a level of technical detail that sits outside the scope of standard compliance work.
This is particularly relevant for:
These areas involve:
- Interpretation of technical activity
- Detailed cost analysis
- Sector-specific understanding
- Increasingly strict HMRC requirements
In practice, this means that even where opportunities exist, they may not always be fully explored without dedicated focus.
2. R&D Tax Relief: A Technical Area
R&D Tax Relief requires more than a financial calculation.
A compliant claim must include:
- A clear technical narrative
- Identification of scientific or technological uncertainty
- A structured breakdown of qualifying costs
- Supporting evidence
HMRC guidance: Corporation Tax: Research and Development (R&D) Relief.
With the introduction of:
- The Additional Information Form
- Advance notification requirements
- Increased enquiry rates
the level of detail required has increased significantly — we cover the full picture in our explanation of the merged R&D scheme.
3. Patent Box: Often Overlooked
Patent Box is frequently underutilised, particularly among SMEs.
It requires:
- Identification of qualifying intellectual property
- Accurate tracking of income derived from that IP
- A structured calculation of qualifying profits
HMRC guidance: Corporation Tax: the Patent Box.
In many cases, businesses carrying out R&D may already be on the path to eligibility but have not yet structured their approach accordingly. Our Patent Box overview explains how the relief works in practice.
4. Embedded Capital Allowances: Hidden Within Property
Embedded Capital Allowances are often overlooked because qualifying assets are not always visible within standard financial records.
These include fixtures and fittings within commercial property such as:
- Electrical systems
- Heating and air conditioning
- Water systems
- Integral features
Where a property has been acquired or refurbished, a detailed review can identify qualifying expenditure that has not previously been claimed.
5. A Collaborative Approach
The most effective approach is collaborative.
Rather than replacing the role of the accountant, a specialist adviser can:
- Work alongside existing advisers
- Provide technical input where required
- Support the preparation of claims
- Ensure compliance with HMRC expectations
This allows the accountant to remain at the centre of the client relationship while ensuring that more complex areas are handled appropriately.
6. Maintaining Client Relationships
For many accountancy firms, the priority is maintaining long-term client relationships.
A structured partnership approach should therefore:
- Be transparent
- Protect the accountant’s position
- Avoid unnecessary complexity
- Ensure clear communication throughout
The aim is to support the client without disrupting existing arrangements — the principles we set out in Your Tax Relief Partners.
7. Compliance and Risk Management
With increased HMRC scrutiny, the quality of claims is more important than ever.
A collaborative approach can help ensure that:
- Claims are properly evidenced
- Technical narratives are robust
- Financial calculations are accurate
- Risk of enquiry is reduced
This benefits both the client and the advising accountant.
8. What This Means in Practice
For accountancy firms and their clients, this approach allows:
- Identification of opportunities that may otherwise be missed
- Access to specialist expertise where required
- Improved quality and consistency of claims
- Reduced compliance risk
It also allows firms to support clients across a broader range of tax reliefs without needing to build internal resource in every area.
