R&D Tax Credit Eligibility

Updated November 2025

If your company does research and development work, you might be missing out on R&D tax credits—which can reduce your Corporation Tax bill or give you cash credits worth thousands of pounds. R&D tax credits allow companies to reduce their Corporation Tax bill or receive cash credits for qualifying research and development expenditure (gov.uk R&D tax relief). SME R&D relief allows small and medium-sized companies to claim 86% enhancement on qualifying R&D costs, or 186% total deduction (100% costs + 86% enhancement). RDEC (Research and Development Expenditure Credit) provides a taxable credit worth 20% of qualifying R&D expenditure for large companies and some SMEs.

Here's what you need to know:

  • R&D tax credits reduce Corporation Tax or provide cash credits — Companies can claim relief worth 14.7%–27% of qualifying R&D costs depending on scheme
  • Qualifying R&D must seek a technological advance — Through resolving scientific or technological uncertainty, not just routine work
  • SMEs get enhanced relief — Small and medium companies can claim higher rates of relief (up to 186% deduction)
  • Claims must be submitted within 2 years — Of the end of the accounting period in which R&D expenditure was incurred

The problem is most companies don't realize their work qualifies for R&D tax credits. They think R&D is only for scientists in labs, don't understand what qualifies, or don't know how to claim. That causes problems—missing out on thousands in tax relief, paying more Corporation Tax than necessary, and not claiming what you're entitled to.

We handle R&D tax credit eligibility assessment for companies doing research and development: R&D eligibility assessment (assessing whether your company's activities qualify as R&D for tax purposes), qualifying costs identification (identifying all qualifying R&D costs including staff, subcontractors, materials, and software), R&D claim preparation (preparing R&D tax credit claims with supporting documentation and technical reports), scheme selection (determining which R&D scheme applies—SME relief, RDEC, or merged scheme), claim submission (submitting R&D claims to HMRC with Corporation Tax returns), and HMRC enquiry support (supporting you during HMRC R&D enquiries if they arise). Whether you're a tech company in Medway developing new software, a manufacturing company in Maidstone improving processes, or a company in Canterbury doing innovative work, we'll handle your R&D tax credit eligibility that works. No missed claims, no overpaid tax—just proper R&D tax credit claims that save you money.

How it works

Step-by-step process for R&D tax credit eligibility assessment:

  1. Discovery call — We chat about your R&D situation: what type of company you are (SME or large), what R&D work you do, what problems you're solving, what costs you incur on R&D, whether you've claimed R&D before, and what you want to achieve.
  2. R&D eligibility assessment — We assess whether your activities qualify:
    • Project review — Review your R&D projects to understand what scientific or technological advances you're seeking
    • Qualifying criteria check — Check whether projects meet R&D qualifying criteria (advance in science/technology, resolving uncertainty)
    • Work activity analysis — Analyze which parts of projects qualify as R&D (vs routine or commercial work)
    • Industry assessment — Assess whether your industry and activities typically qualify for R&D relief
    • Eligibility conclusion — Determine whether your company's activities qualify for R&D tax credits
    R&D eligibility assessment identifies whether you can claim R&D tax credits.
  3. Qualifying costs identification — We identify all qualifying R&D costs:
    • Staff costs — Identify staff time spent on qualifying R&D (salaries, NI, pensions, expenses)
    • Subcontractor costs — Identify R&D work outsourced to subcontractors or freelancers
    • Materials and consumables — Identify materials, heat, light, power used in R&D
    • Software costs — Identify software licenses, data, and cloud costs used for R&D
    • Clinical trial costs — Identify payments to clinical trial subjects (if applicable)
    • Cost apportionment — Apportion costs between qualifying R&D and non-qualifying work
    Qualifying costs identification ensures you claim for all eligible costs.
  4. Scheme selection — We determine which R&D scheme applies:
    • Company size assessment — Determine whether you're SME (fewer than 500 employees, turnover less than €100m or balance sheet less than €86m) or large company
    • Accounting period check — Check when your accounting period starts (affects which schemes are available)
    • Scheme eligibility — Determine which scheme applies (SME relief, RDEC, merged scheme, ERIS)
    • Relief rate calculation — Calculate relief rates available under applicable scheme
    • Scheme recommendation — Recommend best scheme for your circumstances
    Scheme selection ensures you claim under the correct scheme and get maximum relief.
  5. R&D claim preparation — We prepare your R&D claim:
    • Technical report — Prepare technical report explaining R&D activities and how they qualify
    • Cost calculation — Calculate total qualifying R&D costs and enhancement/credit amounts
    • Supporting documentation — Compile supporting documentation (invoices, payroll records, project documentation)
    • Claim forms — Complete R&D claim forms for Corporation Tax return
    • Documentation package — Prepare comprehensive documentation package for HMRC
    R&D claim preparation ensures your claim is properly documented and submitted correctly.
  6. Claim submission — We submit your R&D claim:
    • Corporation Tax return — Include R&D claim in your Corporation Tax return (CT600)
    • Claim submission — Submit claim to HMRC with supporting documentation
    • Deadline compliance — Ensure claim submitted within 2-year deadline from end of accounting period
    • Submission confirmation — Confirm receipt of claim by HMRC
    • Processing tracking — Track claim processing and payment (if applicable)
    Claim submission ensures your R&D claim is filed correctly and on time.
  7. HMRC enquiry support — We support you during enquiries:
    • Enquiry handling — Handle HMRC R&D enquiries and requests for information
    • Additional documentation — Provide additional documentation if HMRC requests it
    • Technical explanations — Provide technical explanations of R&D activities if needed

Why R&D tax credit eligibility assessment costs what it does:

  • R&D eligibility assessment requires understanding technical projects and applying HMRC R&D criteria correctly
  • Qualifying costs identification requires detailed analysis of company costs and apportionment between R&D and non-R&D
  • Technical report preparation requires writing detailed technical explanations of R&D activities
  • Claim preparation requires compiling comprehensive documentation and completing claim forms correctly
  • Scheme selection requires understanding different R&D schemes and determining which applies
  • HMRC enquiry support requires responding to detailed technical questions about R&D activities

Timeline: R&D eligibility assessment typically takes 2-3 weeks from when we receive project information and documentation. R&D claim preparation takes 4-8 weeks depending on complexity and number of projects. Claims are submitted with Corporation Tax returns (due 12 months after company year-end, or earlier if filing early). HMRC typically processes R&D claims within 28-35 days for straightforward claims, longer for complex claims.

Payment: R&D eligibility assessment fees are usually charged upfront. R&D claim preparation fees are typically charged 50% upfront and 50% on submission, or in installments. Some providers charge percentage of claim value (we charge fixed fees). We'll discuss payment options when we understand your needs.

No hidden fees. R&D tax credit eligibility assessment price includes assessment, costs identification, scheme selection, claim preparation, and submission. HMRC enquiry support is separate if needed. We don't charge percentage of claim value—fixed fees only.

FAQs

R&D Tax Credit Eligibility - Frequently Asked Questions

Common questions about R&D tax credits, eligibility, and claim preparation

R&D tax credits are government tax reliefs that allow companies to reduce their Corporation Tax bill or receive cash credits for qualifying research and development expenditure. Companies doing R&D can claim relief worth 14.7%–27% of qualifying R&D costs depending on which scheme applies (SME relief, RDEC, merged scheme, ERIS). The relief reduces Corporation Tax liability or provides cash credits for loss-making companies. R&D tax credits are designed to incentivize UK companies to invest in innovation and research and development.
You're eligible for R&D tax credits if: your company is subject to UK Corporation Tax (limited company, PLC, etc.), you do qualifying R&D activities (seeking advance in science or technology, resolving scientific or technological uncertainty), you incur qualifying R&D costs (staff, subcontractors, materials, software, etc.), and your accounting period is within claim deadline (2 years from end of period). The key is whether your work qualifies as R&D—it doesn't need to be successful, just genuine R&D seeking a technological advance. We can assess whether your activities qualify for R&D tax credits.
To claim R&D tax credits, you need to: assess whether your activities qualify as R&D for tax purposes, identify all qualifying R&D costs (staff, subcontractors, materials, software), determine which R&D scheme applies (SME relief, RDEC, merged scheme), prepare technical report explaining your R&D activities, complete R&D claim forms in your Corporation Tax return, submit claim to HMRC within 2-year deadline, and provide supporting documentation if requested. Claims are submitted with your Corporation Tax return. We can help you prepare and submit R&D tax credit claims correctly.
Qualifying R&D for tax credits must: seek an advance in a field of science or technology (developing something new or appreciably improving something), resolve scientific or technological uncertainty (uncertainty that competent professionals can't readily resolve), involve systematic investigation (methodical research and development), and be in field of science or technology (not arts, humanities, or social sciences). R&D doesn't need to be successful to qualify—failed projects can still qualify. The key is seeking a technological advance through resolving uncertainty, not just routine work or commercial activities. We can assess whether your work qualifies.
How much you can claim depends on which R&D scheme applies and your qualifying costs. For accounting periods from April 2024: merged scheme provides ~14.7%–16.2% relief, ERIS provides 12.5%–27% for qualifying SMEs. For periods before April 2024: SME relief provides up to 186% deduction or cash credits, RDEC provides ~15% credit. The amount depends on your qualifying R&D costs (staff, subcontractors, materials, software). For example, £100,000 qualifying costs could generate £14,700–£27,000 in relief depending on scheme. Average SME claims are around £81,000, average large company claims are around £291,000. We can help calculate potential claim value for your company.
SME R&D relief is the R&D tax credit scheme for small and medium-sized enterprises (fewer than 500 employees, turnover less than €100m or balance sheet less than €86m). For accounting periods before April 2024, SME relief provides up to 186% deduction (100% costs + 86% enhancement) or cash credits for loss-making companies. From April 2024, SMEs use the merged scheme (unless eligible for ERIS). SME relief is more generous than large company schemes, providing higher rates of relief. However, eligibility criteria are strict—you must be a genuine SME and not have received certain state aid. We can help determine whether you qualify for SME relief.
