R&D Tax Relief – FAQs

Qualifying R&D involves projects that seek an advance in science or technology (including pure mathematics) by resolving scientific or technological uncertainties that a competent professional cannot easily address. Examples include developing new software algorithms, improving manufacturing processes, or creating sustainable materials.

UK companies subject to Corporation Tax, including SMEs (fewer than 500 employees, turnover under €100m, or balance sheet under €86m) and large companies, can claim if they undertake qualifying R&D activities. Partnerships, sole traders, charities, and certain overseas entities are typically ineligible.

Eligible costs include staff salaries, employer’s NIC, pension contributions, reimbursed expenses, consumables (e.g., materials, heat, light, power), software, data, cloud computing (since April 2023), clinical trial volunteer payments, and certain subcontractor costs. Capital expenditure may qualify if classified as intangible assets.

Under the merged scheme, companies receive a 20% taxable credit (net benefit 15% at 25% corporation tax or 16.2% at 19% tax). R&D-intensive SMEs (≥30% R&D expenditure) under ERIS can claim a 186% super-deduction and 14.5% cash credit for losses, subject to the PAYE/NIC cap.

The merged scheme (from April 2024) offers a 20% taxable credit for all companies. ERIS is for loss-making SMEs with R&D expenditure ≥30% of total expenditure, providing a 186% super-deduction and 14.5% cash credit for surrendered losses, aimed at highly innovative SMEs.

A mandatory Additional Information Form (AIF) detailing up to 10 representative projects, uncertainties, advances, and costs is required, alongside a technical narrative. Supporting records (e.g., timesheets, invoices, test data, project plans) must be retained for potential HMRC enquiries.

HMRC typically processes claims within 40 days, but complex, first-time, or enquired claims may take longer, sometimes months, especially during peak periods (e.g., December, March).

Yes, certain subcontractor costs qualify, but overseas subcontractor costs are generally excluded unless the R&D cannot be conducted in the UK. Under the merged scheme, contracted-out R&D may qualify if it meets specific criteria, but SMEs subcontracted by large companies may be limited to the 20% credit.

Pre-notification is a mandatory requirement introduced by HMRC in August 2023 for UK companies claiming Research and Development (R&D) tax relief for the first time or after a three-year gap. Businesses must submit a Claim Notification Form (CNF) within six months of their accounting period’s end, detailing their intent to claim. This applies to claims under both the merged scheme and ERIS. Failure to pre-notify can invalidate claims.

Claims must be submitted within two years of the end of the accounting period in which R&D occurred (e.g., by December 31, 2026, for a period ending December 31, 2024).

Provide a robust technical narrative, accurate AIF, and detailed cost breakdowns. Retain comprehensive records (e.g., trial data, project logs). Engaging a reputable R&D tax advisor can ensure compliance and minimise risks of enquiries or penalties.

For loss-making companies, payable cash credits are capped at £20,000 plus 300% of PAYE and NIC liabilities. This limits the cash receivable, particularly for companies with low staff costs, affecting cash flow planning.

Yes, UK companies can claim R&D tax credits alongside grants, but restrictions apply to avoid double-funding. Costs covered by grants classified as subsidies cannot be claimed under R&D tax relief, potentially limiting SMEs to the merged scheme’s 20% taxable credit instead of the more generous ERIS. Non-subsidy grants allow full claims if costs are apportioned correctly. Clear documentation, including the mandatory Additional Information Form, is essential to comply with HMRC’s subsidy control rules and increased scrutiny.

Divide qualifying R&D expenditure by total company expenditure. If the ratio is ≥30%, loss-making SMEs qualify for ERIS. Track R&D costs (e.g., staff, materials) separately from non-R&D costs (e.g., marketing) to ensure accuracy.

Generally, no, unless the R&D cannot be conducted in the UK due to specific conditions (e.g., geological or environmental factors). HMRC requires justification, and overseas subcontractor costs are often excluded.

The AIF, mandatory since August 2023, details R&D projects, uncertainties, advances, and costs to ensure transparency and combat fraud. It must be submitted online before the Corporation Tax return to validate the claim.

For profitable companies, the 20% taxable credit (merged scheme) reduces tax liability, while ERIS’s 186% super-deduction lowers taxable profits. For loss-making companies, surrendered losses yield a cash credit (14.5% for ERIS), subject to the PAYE/NIC cap.

Yes, if the project sought to resolve scientific or technological uncertainties, even if unsuccessful. The focus is on the attempt to advance science or technology, not the outcome.

HMRC are now reviewing 1 in 5 claims. Should they discover issues with the claim, the claim could be reduced or rejected with possible repayment of credits with interest, penalties for errors or fraud, or broader tax audits. Responding to an enquiry requires significant time and resources to compile documentation, respond to HMRC queries, and potentially attend meetings.

Using a specialist is advisable, especially for complex or first-time claims, as they can identify qualifying activities, eligible costs and ensure compliance, reducing the risk of HMRC enquiries. Look for a specialist who will defend the claim on your behalf – and not charge extra for doing so if they prepared the claim in the first place.

HMRC’s Advance Assurance service is a voluntary process in the UK that allows first-time claimants of Research and Development (R&D) tax relief to seek pre-approval from HMRC to confirm that their proposed R&D activities and costs qualify for tax relief. Introduced to reduce uncertainty and the risk of future enquiries, it is particularly beneficial for small and medium-sized enterprises (SMEs) navigating the complexities of R&D tax credits.
