R&D Tax Credits Accountant in Birmingham: Rates & How to Claim

Quick Answer

An R&D tax credits accountant in Birmingham identifies qualifying research and development activity, calculates your claim under HMRC’s merged R&D scheme, and prepares the mandatory Additional Information Form alongside your Corporation Tax return. Since April 2024, most companies claim under a single merged scheme worth roughly 15–16.2p of tax benefit per £1 of qualifying spend, while loss-making, R&D-intensive SMEs can claim under the more generous ERIS scheme, worth around 27p per £1.

Why Trust This Guide?

This guide is written and reviewed by a CIMA-qualified accountant with 15+ years of UK practice experience, based on HMRC’s current merged R&D scheme and ERIS rules for accounting periods beginning on or after 1 April 2024.

Key Takeaways

• The old SME and RDEC schemes merged into a single scheme for accounting periods starting on or after 1 April 2024
• The merged scheme gives a 20% taxable credit – a net benefit of roughly 15p per £1 spent at the 25% Corporation Tax rate, or around 16.2p per £1 for loss-making companies
• Loss-making SMEs with R&D spend of at least 30% of total costs can claim under ERIS instead, worth roughly 27p per £1
• An Additional Information Form is mandatory for every claim, submitted before or alongside your Corporation Tax return
• Claims must be made within two years of the end of the relevant accounting period

Key Terms Explained

• Merged Scheme: The single R&D tax relief scheme that replaced the separate SME and RDEC schemes for accounting periods starting on or after 1 April 2024.
• ERIS (Enhanced R&D Intensive Support): A more generous scheme for loss-making SMEs whose qualifying R&D spend is at least 30% of total costs.
• Additional Information Form: A mandatory HMRC online form describing your R&D projects and costs, required before or alongside your Corporation Tax return.
• Qualifying Expenditure: Costs HMRC accepts as R&D spend – mainly staff time, subcontractors, software, and consumables used directly on the project.

Who Can Claim R&D Tax Credits?

Any UK limited company subject to Corporation Tax can potentially claim, provided it has undertaken a project that sought an advance in science or technology by resolving scientific or technological uncertainty. This is a broader definition than most business owners expect – it isn’t limited to labs and life sciences. We regularly see valid claims from software companies solving genuinely difficult technical problems, manufacturers improving processes, and product businesses developing new formulations or materials, provided the work goes beyond routine application of existing techniques.

Accountant Insight: The most common reason a claim gets rejected or reduced isn’t ineligibility – it’s poor documentation. HMRC wants to see the technical uncertainty and the work done to resolve it described clearly, not just a list of costs.

R&D Activity in Birmingham: What We See

Birmingham’s manufacturing and engineering base, concentrated around the Jewellery Quarter and the wider West Midlands, produces some of the most straightforward R&D claims we see – process improvements and material development that clearly meet HMRC’s definition, but are rarely flagged as R&D by the businesses doing the work.

The Merged R&D Scheme: Rates for 2026/27

For accounting periods beginning on or after 1 April 2024, most companies – both SMEs and larger businesses – claim under a single merged scheme, structured like the old RDEC scheme. You receive a taxable credit worth 20% of qualifying R&D expenditure, which is included as taxable income and then either reduces your Corporation Tax bill or is paid out (net of tax) if you’re loss-making.

Scenario	Credit Rate	Approx. Net Benefit per £1 Spent
Profitable company, 25% CT rate	20% taxable credit	~15p
Profitable company, 19% CT rate (small profits)	20% taxable credit	~16.2p
Loss-making company (standard merged scheme)	20% taxable credit	~16.2p
Loss-making, R&D-intensive SME (ERIS)	86% additional deduction + 14.5% credit	~27p

Enhanced R&D Intensive Support (ERIS)

If your company is loss-making, qualifies as an SME (broadly, fewer than 500 employees and under £100m turnover or £86m gross assets), and your qualifying R&D expenditure represents at least 30% of your total costs, you’re eligible for ERIS instead of the standard merged scheme. ERIS gives an 86% additional deduction on qualifying costs plus a payable cash credit of 14.5% on the resulting surrenderable loss – an effective benefit of around 27p per £1 of qualifying spend, paid in cash even though the company hasn’t yet turned a profit.

What Counts as Qualifying R&D Expenditure?

Qualifying costs typically include staff costs for those directly working on the R&D project (including a proportion of time for mixed roles), certain subcontractor and externally provided worker costs, software licences used directly in the R&D, consumable items used up in the project, and some utility costs apportioned to R&D activity. It does not generally include capital expenditure, rent, or the cost of producing and selling the finished product once development is complete.

What an R&D Tax Credits Accountant Actually Does

An R&D tax credits accountant works with you (and often your technical team) to identify which projects and costs genuinely qualify, quantify the qualifying expenditure accurately, prepare the technical narrative HMRC requires in the Additional Information Form, and submit the claim alongside your Corporation Tax return – while making sure the claim is defensible if HMRC opens an enquiry, which has become more common as compliance checks have increased.

A Worked Example

A software company based in Birmingham spends £120,000 in a year on two developers working substantially on a genuinely novel technical problem, plus £15,000 of cloud infrastructure and software costs directly tied to the project. Qualifying expenditure comes to roughly £135,000. Under the standard merged scheme at a 16.2p net benefit (loss-making), that’s a cash benefit of around £21,870. If the same company qualified for ERIS instead because R&D made up over 30% of its total costs, the benefit at ~27p per £1 would be closer to £36,450 – a substantial difference that makes it worth checking eligibility for both routes rather than assuming the standard scheme applies.

Areas We Serve Across Birmingham

We work with clients across all Birmingham postcode districts (B1–B99) and the wider region, entirely online. In practice, that includes professional services clients around the Colmore Business District, manufacturing and trade businesses in the Jewellery Quarter, a growing tech and creative scene around Digbeth, and construction subcontractors and landlords across the wider West Midlands. Everything is handled digitally, so there’s no need to visit an office to get started.

The Additional Information Form & Claim Process

Since August 2023, every R&D claim must be supported by an Additional Information Form submitted through HMRC’s online service before or alongside the Corporation Tax return. It requires a description of the qualifying projects, the scientific or technological uncertainties addressed, and a breakdown of qualifying costs by category. Claims without this form are rejected outright, regardless of merit, so this step can’t be skipped or left as an afterthought.

How Much Does It Cost?

R&D tax credit claim preparation is usually charged either as a fixed fee based on the complexity of the claim, or as a percentage of the benefit secured – commonly somewhere in the 10–20% range for percentage-based pricing, though this varies with claim size and complexity. Ask upfront how the fee is structured and get it in writing before work begins, since claim sizes and structures vary considerably between businesses.

Should You Use an R&D Specialist? (Decision Framework)

If your claim is small and straightforward – a single clear project, well-documented costs – your regular accountant may be able to handle it. As claims grow in size or technical complexity, or if you’ve never claimed before and aren’t sure whether your work qualifies, a specialist becomes worthwhile: the difference between a well-argued technical narrative and a vague one can be the difference between a claim sailing through and one triggering an HMRC enquiry.

DIY vs Professional Accountant

	DIY Claim	R&D Specialist
Cost	No fee, but higher risk of errors	Fixed fee or % of benefit, typically 10–20%
Technical narrative quality	Often too vague for HMRC’s expectations	Written to HMRC’s expected standard
Eligibility for ERIS	Easy to miss if unfamiliar with the rules	Checked and applied where eligible
Enquiry risk	Higher, especially for first-time claims	Lower – claims prepared defensively

What Crossing the 30% R&D Intensity Threshold Is Actually Worth

ERIS eligibility is a hard cutoff – your qualifying R&D spend must be at least 30% of total company costs. Below that line, you’re on the standard merged scheme; cross it, and the cash benefit on the same spend jumps by roughly 10.8p per £1. Here’s what that threshold is worth in cash terms at different company sizes:

For a loss-making, R&D-heavy business sitting just under the 30% intensity line, this table matters. It’s worth checking two things:

• Whether borderline costs could be reclassified as qualifying R&D spend
• Whether timing spend within the accounting period could tip you over the threshold

As the table shows, the cash difference is rarely trivial.

Common Mistakes People Make

• Assuming R&D relief only applies to labs and scientific research, missing genuinely qualifying software or process development work
• Submitting vague technical narratives that don’t clearly explain the uncertainty being resolved
• Forgetting the mandatory Additional Information Form, resulting in an automatically rejected claim
• Not checking eligibility for ERIS, potentially leaving a significantly larger benefit unclaimed
• Including ineligible costs such as capital expenditure or routine, non-technical work, which weakens the credibility of the whole claim

Frequently Asked Questions

What is the R&D tax credit rate for 2026/27?

Most companies claim under the merged scheme, worth a 20% taxable credit – a net benefit of roughly 15–16.2p per £1 of qualifying spend depending on profitability. Loss-making, R&D-intensive SMEs can claim under ERIS instead, worth around 27p per £1.

What is the difference between the merged scheme and ERIS?

The merged scheme applies to most companies and gives a 20% taxable credit. ERIS is only available to loss-making SMEs where R&D spend is at least 30% of total costs, and gives a larger effective benefit of around 27p per £1.

Does my software company qualify for R&D tax credits?

It can, if the work involves resolving a genuine technological uncertainty rather than routine application of known techniques. Many software businesses qualify without realising it.

What is the Additional Information Form?

It’s a mandatory HMRC form describing your qualifying R&D projects and costs, which must be submitted before or alongside your Corporation Tax return for every claim.

How far back can I claim R&D tax credits?

Claims must be made within two years of the end of the relevant accounting period, so you can typically claim for your current and previous accounting period, but not further back.

Can a loss-making company claim R&D tax credits?

Yes. Loss-making companies can receive a payable cash credit under either the standard merged scheme or, if eligible, the more generous ERIS scheme.

What costs qualify for R&D tax relief?

Staff costs for those working directly on the project, some subcontractor and externally provided worker costs, software, consumables, and a proportion of relevant utility costs typically qualify.

Can an R&D tax credits accountant in Birmingham help remotely?

Yes. Claim preparation is handled digitally – reviewing your technical work and costs, and submitting everything online – regardless of where your business is based.

Does HMRC check R&D claims?

Yes, compliance checks on R&D claims have increased significantly in recent years, which makes clear, well-documented technical narratives more important than ever.

How is the R&D tax credit accountant’s fee usually charged?

Either as a fixed fee for preparing the claim, or as a percentage of the benefit secured, commonly in the region of 10–20% depending on complexity.

Final Thoughts

This guide is part of our full accountant in Birmingham overview, covering all the services Birmingham businesses typically need.

R&D tax credits remain one of the most under-claimed reliefs available to UK companies, largely because the definition of qualifying work is broader than most people assume. If your business has genuinely pushed past a technical or scientific uncertainty in the last two accounting periods, it’s worth getting the claim properly assessed rather than assuming it doesn’t apply.
