Reporting Burden	Moderate (technical report required)	High (detailed project reports, audits)

R&D Tax Credits: How They Work

R&D tax credits reward companies for innovation expenditure through the tax system. You claim relief on qualifying costs retrospectively, receiving either corporation tax reduction or cash payment.

What Qualifies as R&D?

Work must seek to achieve an advance in science or technology by resolving scientific or technological uncertainty. This is broader than many businesses realise. Qualifying projects include: developing new products/processes/services, improving existing ones significantly, or using science/technology in new ways.

Examples that qualify:

• Developing software with novel algorithms or architectures
• Creating new materials or chemical processes
• Engineering products with performance improvements requiring technical problem-solving
• Adapting technologies to new applications where outcomes are uncertain

Examples that don't qualify:

• Routine upgrades or updates using established methods
• Market research or consumer testing
• Work in arts, humanities, or social sciences (unless solving technical problems)
• Cosmetic changes without technical innovation

How Much Can You Claim?

Two schemes exist depending on company size and profit status:

SME Scheme (most companies under 500 employees)

You can claim additional deduction of 86% on qualifying R&D expenditure. For profitable companies, this typically means 19.25% of R&D costs back as corporation tax reduction. Loss-making companies can claim 10% as cash payment.

Example: £100,000 R&D expenditure

Profitable SME: ~£19,250 benefit

Loss-making SME: £10,000 cash payment

RDEC Scheme (larger companies or grant-funded R&D)

Research and Development Expenditure Credit provides 20% of qualifying expenditure before tax. After corporation tax, this nets approximately 15% benefit.

Example: £100,000 R&D expenditure

Net benefit: ~£15,000

The Claiming Process

1.
Identify qualifying projects: Review your R&D activities over the accounting period. Most companies find they have more qualifying work than initially thought.
2.
Calculate qualifying expenditure: Include staff costs (salaries, NICs, pensions for R&D staff), subcontractor costs, consumables, and software used directly in R&D.
3.
Prepare technical report: Document the scientific/technological uncertainties, work undertaken to resolve them, and why existing knowledge was insufficient. This is critical—poor reports get rejected.
4.
Submit with corporation tax return: Claims must be made within two years of accounting period end. HMRC reviews and either accepts, queries, or challenges the claim.

Reality check: 73% of first-time claimants use specialist R&D tax advisors. While not legally required, specialists typically increase claim values by 20-40% through identifying qualifying activities companies miss and structuring claims optimally.

Innovation Grants: How They Work

Innovation grants fund specific future projects through competitive application processes. Unlike tax credits (retrospective reward for work done), grants provide upfront funding for proposed innovations.

• Job creation potential
• Sector development impact

Value for Money

• Realistic budget and timeline
• Appropriate grant level requested
• Justified costs
• Additionality (wouldn't happen without grant)

Which Should You Choose? Decision Framework

The optimal strategy often involves using both schemes strategically. Here's how to decide for specific situations:

Scenario 1: Ongoing Innovation Activity

Your company regularly works on new products, processes, or improvements. Innovation is part of normal operations rather than distinct one-off projects.

→ Prioritise R&D Tax Credits

•Claim retrospectively on work you're doing anyway
•No need to define project boundaries or predict outcomes
•High success rate if work genuinely qualifies
•Funds can be used for any business purpose including more R&D

Scenario 2: Ambitious Defined Project Beyond Current Capacity

You've identified a significant innovation opportunity but lack resources to pursue it. Project requires hiring additional staff, expensive equipment, or partnering with universities/specialists.

→ Prioritise Innovation Grants

•Upfront funding enables projects you couldn't otherwise afford
•Covers 50-70% of costs, making ambitious projects financially viable
•External validation valuable for attracting other investment
•Access to wider Innovate UK support network and connections

Note: If you win innovation grant, switch to RDEC scheme for R&D tax credits on that project (can't claim SME scheme on grant-funded work).

Scenario 3: Established Company with Resources

You can fund innovation internally but want to maximise financial return and de-risk investment in larger projects.

→ Use Both Strategically

•Claim R&D tax credits on all qualifying innovation work
•Apply for innovation grants for 2-3 highest-potential projects annually
•Use grant success (or application process feedback) to validate project direction
•Pursue grant-funded projects more aggressively given reduced financial risk

Scenario 4: Early-Stage Company, Limited Track Record

You're a startup or young company with innovative product but limited historical R&D expenditure to claim tax credits on.

→ Prioritise Innovation Grants (but claim tax credits too)

•Grants provide meaningful funding even with no tax history
•Loss-making SMEs can still claim R&D tax credits as cash payments (10% of expenditure)
•Grant success strengthens credibility with investors and customers
•Claim tax credits on grant match-funding and non-grant-funded R&D

Frequently Asked Questions

Can I claim both R&D tax credits and innovation grants on the same project?

Yes, but with limitations. Grant-funded work must be claimed under RDEC scheme (not SME scheme), which provides lower benefit (~15% vs ~19.25%). You can still claim SME scheme on the match-funding portion you contribute. Many companies use grants for one project whilst claiming SME tax credits on other R&D activities.

Which provides better financial return?

Innovation grants typically provide larger absolute amounts (£25k-£2m vs average £35k R&D tax credit claim). However, R&D tax credits have much higher success rates (92% vs 18-25%). Expected value calculation: £35,000 tax credit with 92% probability = £32,200 expected value. £150,000 grant with 20% probability = £30,000 expected value. But this is oversimplified—grants fund work you might not otherwise undertake, while tax credits reward work you're doing anyway.

Which is easier to get?

R&D tax credits are significantly easier if your work genuinely qualifies. Innovation grants require excellent applications competing against many others. One study found average application success on first attempt: R&D tax credits 78%, innovation grants 12%. However, "easier" doesn't mean "better"—they serve different purposes.

How much do specialist advisors cost for each?

R&D tax credit advisors typically charge 15-25% of claim value (often no win/no fee). On £50k claim, expect £7,500-12,500 fees. Innovation grant consultants charge £5,000-15,000 for substantial applications or 8-12% of grant value if successful. Some companies develop internal capability after using specialists for first claims/applications.

What if my R&D tax credit claim is challenged by HMRC?

HMRC challenges approximately 15-20% of claims, usually requesting additional information rather than outright rejection. Common issues: insufficient technical detail in reports, misunderstood qualifying rules, poor cost apportionment. Having specialist advisors significantly reduces challenge risk and improves resolution outcomes when challenges occur. Most challenges are resolved successfully with additional documentation.

The Optimal Strategy: Using Both

Most innovative companies benefit from pursuing both R&D tax credits and innovation grants strategically rather than choosing one exclusively. R&D tax credits provide reliable, modest funding for ongoing innovation work with minimal bureaucracy. Innovation grants fund ambitious projects that might not otherwise happen.

Suggested approach: Claim R&D tax credits annually on all qualifying work (should be routine part of your finance process). Separately, identify 1-3 highest-impact potential projects annually where grant funding would enable significantly more ambitious execution. Apply for relevant innovation grants for these specific projects.

This approach provides steady reliable funding from tax credits (supporting ongoing innovation capability) plus occasional larger injections from successful grants (enabling transformational projects). Companies following this model report 37% higher innovation outputs than those using single funding routes.

Remember: Neither scheme should dictate your innovation strategy. Innovate because market opportunities exist and your capabilities allow exploitation. Use tax credits and grants to accelerate and de-risk innovation, not as primary motivation for R&D activities.
