UK Research & Development (R&D) Tax Relief

HMRC has dramatically tightened R&D claim standards. We help innovative UK companies identify qualifying projects and structure 100% compliant technical submissions to unlock cash repayments.

Navigating the UK R&D Tax Landscape

Following recent legislative reforms, claims for accounting periods beginning on or after 1 April 2024 operate under the Merged RDEC scheme, alongside the Enhanced R&D Intensive Support (ERIS) regime for loss-making, research-heavy SMEs.

The Standard Regime

Merged RDEC Scheme

Provides a 20% taxable expenditure credit on qualifying spend, delivering a net Corporation Tax reduction of up to 15% (after 25% CT).

Loss-Making SMEs

Enhanced R&D Intensive (ERIS)

For companies where qualifying R&D spend represents at least 30% of total expenditure. Unlocks a payable cash tax credit of up to 26.97%.

What Qualifies as R&D for Tax Purposes?

Under DSIT guidelines, your project must seek an advance in overall science or technology by overcoming technological uncertainties that could not be readily resolved by a competent professional.

Staffing & Subcontractor Costs: Gross salaries, employer Class 1 NICs, and pension contributions for engineers, developers, and scientists directly engaged in R&D.
Cloud Computing & Data Licenses: Software subscriptions, cloud hosting (AWS, GCP, Azure), data sets, and machine learning infrastructure used in R&D trials.
Consumables & Prototypes: Raw materials, power, laboratory supplies, and prototype fabrication directly consumed during testing.

Mandatory AIF Compliance & Inquiry Defense

All claims must now be submitted with a digital Additional Information Form (AIF) prior to the CT600 return. HMRC automatically rejects submissions lacking a valid AIF reference.

We draft rigorous, evidence-backed technical narratives authored in collaboration with your technical leads, ensuring that project boundaries, baseline assessments, and uncertainties are defended under HMRC manual guidelines.
