Research and Development (R&D) tax credits are a UK government incentive designed to encourage companies to invest in innovation. From April 2024, a merged R&D relief scheme applies to most companies, replacing the previous separate SME scheme and RDEC (Research and Development Expenditure Credit) for large companies. Under the merged scheme, companies receive an above-line credit of 20% on qualifying R&D expenditure — meaning the credit reduces the tax liability and, if it exceeds the tax due, can be repaid in cash (subject to conditions). For loss-making R&D-intensive SMEs (those where qualifying R&D expenditure is at least 30% of their total expenditure), an enhanced rate of 27% applies. Qualifying expenditure includes staff costs directly engaged in R&D, consumables and software used in R&D, subcontractor costs (capped at 65% of the amount paid), and certain externally provided workers. The Patent Box regime — separate from R&D tax credits — allows profits from qualifying patented intellectual property to be taxed at 10% rather than the standard corporation tax rate. HMRC introduced a pre-notification requirement from April 2023, meaning companies claiming R&D relief for the first time (or after a gap) must notify HMRC within 6 months of the end of the accounting period.
R&D credit (merged scheme) = qualifying R&D expenditure × 20%; R&D-intensive SME rate = qualifying expenditure × 27%; Net tax saving = credit × (1 - corporation tax rate)
- 1Identify qualifying R&D projects — these must seek to achieve an advance in science or technology and involve the resolution of scientific or technological uncertainty
- 2Calculate qualifying R&D expenditure: staff costs (salary, employer NI, pension) for R&D employees; software and consumables used in R&D; subcontractor costs (capped at 65% of payment); externally provided workers
- 3Apply the 20% RDEC credit rate to total qualifying expenditure under the merged scheme (or 27% if the company is an R&D-intensive loss-making SME)
- 4The credit is an 'above-the-line' credit — it is credited to the profit and loss account and then offset against the corporation tax liability
- 5If the credit exceeds the corporation tax liability, the net amount (after a notional 25% corporation tax deduction) can be refunded in cash
- 6Pre-notify HMRC using the online service within 6 months of the accounting period end if this is a first-time or renewed claim
- 7Include the R&D claim on the CT600 corporation tax return and submit an Additional Information Form (AIF) with supporting documentation
£200,000 × 20% = £40,000 credit. Tax before credit: £300,000 × 25% = £75,000. Tax after credit: £75,000 - £40,000 = £35,000.
The £40,000 above-line credit directly reduces the corporation tax bill from £75,000 to £35,000, saving the company £40,000.
27% × £500,000 = £135,000 credit. Cash refund = £135,000 × (1 - 25%) = £101,250 if no tax to offset.
An R&D-intensive loss-making SME where R&D spend is over 30% of total costs qualifies for the enhanced 27% rate. The net cash refund is the credit less a notional 25% corporation tax withholding.
Patent Box and R&D credits are separate regimes that can be used together for innovation-led companies.
Companies can simultaneously claim R&D credits on development costs and Patent Box relief on the resulting IP profits, combining two powerful tax incentives.
£100,000 × 65% = £65,000 cap on subcontractor inclusion. Combined: £80,000 + £65,000 = £145,000 × 20% = £29,000.
Under the merged scheme, payments to unconnected subcontractors are included at 65% of the amount paid. Connected party subcontractors are limited to relevant expenditure.

What qualifies as R&D for tax purposes?
R&D must seek an advance in overall knowledge or capability in science or technology (not just the company's own knowledge), and must involve the resolution of scientific or technological uncertainty. Routine analysis, software development with no technical uncertainty, and commercially-driven projects without innovation typically do not qualify. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can all companies claim R&D tax credits?
Any UK company subject to corporation tax can potentially claim R&D relief. Companies must be undertaking qualifying R&D activities and have the relevant costs. As of April 2024, the merged scheme applies to all companies regardless of size. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the HMRC pre-notification requirement?
From April 2023, companies that have never claimed before (or have not claimed in the previous 3 years) must notify HMRC within 6 months of the end of the accounting period that they intend to claim R&D relief. Failure to do so means the claim will be rejected. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
How long does it take HMRC to process R&D claims?
Under the new merged scheme with the Additional Information Form, HMRC aims to process claims within 28 days if all information is complete. Complex or large claims may take longer. Delays occur when HMRC requires additional evidence. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is the Additional Information Form (AIF)?
The AIF must be submitted to HMRC before or at the same time as the CT600 containing an R&D claim. It requires a description of the qualifying projects, the main areas of uncertainty resolved, and the expenditure breakdown by category. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can I claim for R&D on products that will be sold?
Yes. R&D does not need to be purely academic — it can be commercially motivated. What matters is that the activity resolves genuine technological uncertainty and seeks an advance in science or technology, not just a technical solution for the company's own business problem. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
What is Patent Box and how does it relate to R&D?
Patent Box is a separate regime allowing profits from qualifying patented inventions to be taxed at 10%. R&D tax credits incentivise the R&D spend; Patent Box incentivises the commercialisation of the resulting intellectual property. Both regimes can be used together. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can I amend a prior year return to claim R&D credits I missed?
Yes. You can amend a corporation tax return up to 2 years after the end of the accounting period to include an R&D claim. This allows companies that did not initially claim to recover credits retrospectively for up to two prior years. This is particularly important in the context of uk r and d tax credit calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise uk r and d tax credit computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Pro Tip
Document R&D activities throughout the year in real time — project logs, technical decision records, and time-tracking data. Retrospective reconstruction is much harder to defend during HMRC compliance checks and may result in claims being reduced or rejected.
Did you know?
The UK R&D tax credit scheme has existed in some form since 2000 and has helped hundreds of thousands of companies innovate. By 2023, HMRC was processing over £7 billion in R&D tax relief per year — making it one of the most generous corporate innovation incentives in the world, though tightening rules are reducing the most aggressive claims.
