Food and Drink Product Development: Reformulation Projects That Qualify for R&D Relief in the UK
A food or drink reformulation project qualifies for Research and Development (R&D) tax relief in the UK when it seeks an advance in food science or process technology by resolving a scientific or technological uncertainty that a competent professional in the field could not readily have resolved using existing public knowledge. Reducing sugar while holding texture and shelf life constant can qualify. Swapping one supplier's vanilla extract for another's, or tweaking a spice level, almost never does. For accounting periods falling in the 2026/27 tax year, the relevant relief runs through the merged R&D scheme or, for loss-making R&D-intensive SMEs, the Enhanced R&D Intensive Support (ERIS) scheme.
I have taken enough food and drink claims through enquiry to say plainly that this is one of the sectors HMRC scrutinises hardest, precisely because the boundary between genuine technical development and ordinary product development is narrower here than in, say, software or engineering. Getting the boundary right, and documenting it properly at the time rather than reconstructing it a year later, is what decides whether a claim survives a compliance check.
The Legal Test, Applied to Reformulation
The statutory definition of R&D for tax purposes has not changed in substance for some years, but HMRC's guidance on applying it was substantially reworked and now sits alongside the Department for Science, Innovation and Technology (DSIT) guidelines. The test has two parts, and both need to be satisfied by the specific project, not by the company's activities in general.
First, the project must seek an advance in science or technology, meaning an advance in the overall knowledge or capability in a field, not merely an advance in your own company's internal know-how. A reformulation that solves a problem your competitors solved years ago, using published or generally known methods, is not seeking an advance even if it is new to you.
Second, that advance must be sought by resolving scientific or technological uncertainty, defined as uncertainty a competent professional working in the field could not readily resolve using existing knowledge that is publicly available or reasonably deducible. HMRC's guidance on qualifying R&D activities is explicit that the uncertainty test is about whether the outcome is achievable using existing knowledge, not about whether the work is difficult, time-consuming, or commercially risky. A project that is expensive and fiddly but technically straightforward for a competent food technologist does not qualify simply because it took months and several failed batches.
This is where most food and drink claims either stand or fall. Commercial risk, market uncertainty, and consumer acceptance risk are not the same thing as technological uncertainty, and HMRC's caseworkers are alert to claims that describe the former while implying the latter.
Reformulation Projects That Genuinely Tend to Qualify
The following categories represent the reformulation work I see succeed most consistently, provided the underlying uncertainty is real and documented.
Sugar, salt, or fat reduction that must preserve structural or sensory function. Sugar in a baked product is not just sweetness; it affects browning, moisture retention, shelf life, and crumb structure. A project to cut sugar content by a defined percentage while holding those properties constant, where the mechanism by which sugar contributes to those properties is not fully predictable from existing formulation science, involves genuine technological uncertainty. A straightforward substitution using a known bulking agent at a rate the supplier's own technical data sheet recommends is a different matter, and rarely qualifies on its own.
Allergen removal or substitution that must preserve a functional role. Egg performs binding, aeration, and emulsification functions that are difficult to replace without altering texture. A project to remove egg from a product while maintaining a defined set of functional and sensory outcomes, where the replacement's behaviour at your specific formulation and process parameters is not predictable in advance, can qualify. Simply buying an off-the-shelf egg replacer and following the manufacturer's stated usage rate, with no further technical resolution required, generally does not.
Shelf-life extension involving genuine microbiological or physicochemical uncertainty. Work to extend shelf life through reformulation, modified atmosphere packaging interaction, or water activity manipulation, where the interaction between the formulation change and microbial or oxidative stability is not established, sits squarely within qualifying R&D. Extending shelf life by simply adding a permitted preservative at its standard usage level is routine formulation, not R&D.
Process scale-up where the formulation behaves differently at production volume. A recipe that performs correctly in a development kitchen or pilot plant does not always behave the same way at full production scale, where heat transfer, mixing shear, or fermentation kinetics change. Where scaling introduces a genuine technical uncertainty, rather than simply requiring recalibration of known parameters, the scale-up work itself can be a qualifying project distinct from the original recipe development.
Alternative protein and plant-based reformulation involving novel technical work. Replacing a dairy or meat component with a plant-based alternative frequently requires resolving texture, mouthfeel, and structural uncertainty that has no established solution, particularly where the substitute needs to replicate a specific functional property such as melt behaviour or fibrous structure. Where the work amounts to swapping in a commercially available, well-documented alternative at its recommended usage rate, the uncertainty threshold is harder to clear.
Fortification and bioavailability challenges. Adding a nutrient to a product while ensuring it remains stable, bioavailable, and does not interact adversely with other ingredients over the product's shelf life can involve real technological uncertainty, particularly with micronutrients sensitive to oxidation, light, or pH.
What Does Not Qualify, and Why HMRC Pushes Back on It
HMRC's caseworkers see a high volume of food and drink claims that describe ordinary new product development dressed up in R&D language, and the following patterns draw scrutiny.
Routine recipe adaptation, such as adjusting a recipe to remove animal-derived ingredients using established, published techniques, does not involve resolving a technological uncertainty even though it requires skill and iteration. Standard ratio adjustments, taste-driven reformulation with no technical constraint being solved, and aesthetic or branding-led changes to appearance, colour, or presentation fall outside the definition, because the uncertainty being resolved is one of consumer preference or commercial judgement rather than science or technology. Market research and consumer testing, however extensive, is not R&D activity in itself, though it can sometimes support or follow a genuinely qualifying technical project.
The distinction I find most useful in practice, and the one I put to clients directly, is this: if a competent food technologist with access to the published literature and standard industry technical data sheets could have told you the likely outcome before you started, the work is very unlikely to qualify, however much testing it actually took to confirm it. If nobody in the field could have told you with confidence whether your specific combination of constraints was achievable, and you had to find out through structured experimentation, that is a different position entirely.
This is also why the professional background of whoever leads the project matters in practice, not as a formal legal requirement but as evidence. A claim led and evidenced by a qualified food scientist or process engineer, who can articulate the specific technical parameters and why the outcome was uncertain, is considerably more defensible than one led by a chef whose documentation describes taste trials and customer feedback rather than technical hypotheses and measured results.
How the Relief Works for 2026/27
For accounting periods beginning on or after 1 April 2024, and continuing through the 2026/27 tax year, the separate SME and RDEC schemes that applied previously have been replaced by a single merged scheme, alongside ERIS for a specific subset of loss-making companies.
The merged scheme applies to most claimant companies, regardless of size, and provides an above-the-line expenditure credit of 20% of qualifying R&D costs. Because the credit is taxable, the net cash benefit works out at roughly 15% of qualifying expenditure for a company paying corporation tax at the 25% main rate, or a little higher for a company on the small profits rate. Full detail on calculating the credit, including how the PAYE and National Insurance contributions cap operates, is set out in HMRC's guidance on working out your Research and Development tax relief.
ERIS is available to loss-making SMEs where qualifying R&D expenditure represents at least 30% of total expenditure for the period. Eligible companies can claim a payable credit worth approximately 27p for every pound of qualifying spend, calculated through a 186% enhanced deduction converted to a cash credit at a 14.5% surrender rate. There is a one-year grace period: a company that met the 30% threshold and claimed under ERIS in one year but drops below it the following year can continue claiming ERIS for that one further year, which matters for food businesses whose R&D intensity can swing with a single large reformulation project finishing or a quieter product development year following it.
For a mid-sized company with fluctuating profitability, which describes a fair number of growing food and drink businesses, the choice between the two schemes in a loss-making year is not automatic, and modelling both is worthwhile before deciding which to claim under, since you cannot claim both for the same expenditure.
Contracted-Out R&D and Overseas Restrictions
Two changes that took effect for accounting periods beginning on or after 1 April 2024 are particularly relevant to food and drink businesses, because this sector relies heavily on external technical input, whether that is a contract food science laboratory, a university partnership, or a specialist reformulation consultancy.
Under the revised contracted-out rules, entitlement to claim generally follows the company that decided to undertake the R&D and bears the financial risk of it, rather than automatically following whichever company physically carried out the work. A food manufacturer that commissions a specialist laboratory to resolve a specific formulation uncertainty, defining the problem and bearing the commercial risk of failure, will usually be the company entitled to claim, with the laboratory unable to claim on the same expenditure. This reverses the position many claimants were used to under the old rules and needs checking carefully wherever a third party is doing technical work on your behalf, since getting it wrong on either side can mean nobody claims validly, or two parties both attempt to claim the same costs.
Relief for payments to overseas subcontractors and externally provided workers is now restricted to work carried out within the UK, with narrow exceptions where conditions necessary for the R&D, such as a specific geographical, environmental, or regulatory factor, are not present in the UK. A food business using an overseas contract research organisation for a reformulation project, perhaps because of specialist expertise concentrated elsewhere, needs to check whether those costs remain eligible before assuming they do.
Getting the Process Right
Since 1 April 2023, most companies claiming for the first time, or whose last claim was more than three years before the relevant claim notification period, must submit a claim notification form to HMRC within six months of the end of the period of account, before the claim itself is made. Missing this deadline invalidates the claim entirely, regardless of how strong the technical case is. Every claim, whatever the company's history, must also be supported by an Additional Information Form submitted before the Company Tax Return, setting out the qualifying projects, the uncertainties addressed, and the costs involved. HMRC's detailed manual, the Corporate Intangibles Research and Development Manual sets out how HMRC interprets the qualifying conditions in depth and is worth consulting directly where a project sits close to the boundary.
The practical habit worth building into a food and drink development function is contemporaneous technical documentation: a short note, written at the point the uncertainty was identified, stating what was not known, what was tried, and what the outcome was, whether the project succeeded or failed. Reconstructing this a year later from lab notebooks, batch records, and someone's memory is possible but considerably weaker as evidence than a record made at the time, and it is the single biggest difference I see between claims that pass through a compliance check smoothly and those that do not.
A Worked Example
A soft drinks manufacturer with a corporation tax accounting period matching the 2026/27 tax year undertakes a project to reduce sugar content in an existing product range by 30% while maintaining viscosity, mouthfeel, and a minimum 12-month shelf life without additional preservatives. The technical team, led by a qualified food scientist, cannot establish from existing published formulation science or supplier technical data whether the combination of a specific fibre-based bulking system and a natural sweetener blend will replicate the mouthfeel and prevent microbial spoilage at the target pH without further preservation, so they run a structured series of trial batches, stability testing, and accelerated shelf-life studies over several months.
Qualifying costs include the food scientist's salary time allocated to the project, consumables used in trial batches, a proportion of laboratory testing costs, and payments to a UK-based accredited testing facility for microbiological and stability analysis. If total qualifying expenditure across the accounting period comes to £180,000 and the company is profitable, claiming under the merged scheme produces an above-the-line credit of £36,000 (20% of £180,000), with a net cash benefit after corporation tax of roughly £27,000. If the same company were loss-making and met the 30% R&D intensity threshold for ERIS, the payable credit would be closer to £48,600 (approximately 27% of £180,000), reflecting the enhanced support available to R&D-intensive companies that are not yet profitable.
Scottish and Welsh Positions
Research and Development tax relief is a reserved matter of UK corporation tax, and the rates, thresholds, and qualifying conditions described above apply identically to companies in Scotland, Wales, England, and Northern Ireland, since corporation tax itself is not devolved. What can differ nationally is the availability of grant funding and innovation support that a food and drink business might combine with an R&D claim, such as funding routed through Scottish Enterprise or the Development Bank of Wales.
Under the merged scheme, receiving a grant or subsidy towards a project no longer restricts which relief you claim under or reduces the rate, which removes a complication that existed under the pre-April 2024 SME scheme, where subsidised R&D expenditure was pushed into the less generous RDEC treatment. It is still sensible to check the specific terms of any grant funding for conditions that affect intellectual property ownership or reporting obligations, since those can have practical consequences for a claim even though the tax mechanics themselves no longer penalise grant-funded projects.
FAQs
Does a project have to succeed to qualify for R&D tax relief?
No. A reformulation project that fails to achieve its target, for example a sugar reduction that ultimately proves technically unachievable at the desired level without unacceptable quality loss, can still qualify, provided the uncertainty was genuine and the work was structured to resolve it. Claims built around a documented failure, where the uncertainty and the attempted resolution are clearly recorded, are often easier to defend than claims describing an unusually smooth success.
Can taste and sensory testing ever form part of a qualifying claim?
Sensory testing can support a qualifying project where it is being used to measure whether a specific technical outcome, such as replicated mouthfeel after removing a functional ingredient, has been achieved. Sensory testing used purely to gauge consumer preference between finished recipe options, with no technical uncertainty being resolved, is not R&D activity in itself.
Do we need an in-house food scientist to make a valid claim, or can a chef lead the project?
There is no formal legal requirement for a specific qualification, but HMRC expects evidence from a competent professional who can explain the technical uncertainty and why it could not be readily resolved using existing knowledge. In practice, claims led by someone with a food science, process engineering, or equivalent technical background, and documented in those terms, are considerably stronger than claims led purely on culinary or sensory grounds.
Does packaging development count as part of a food and drink R&D claim?
Packaging science can qualify separately from or alongside product reformulation where it involves resolving genuine technical uncertainty, such as developing a barrier film or active packaging system that must meet specific, previously unachieved shelf-life or migration performance criteria. Purely cosmetic packaging redesign does not qualify.
We use an external laboratory for our reformulation trials. Who claims the relief, us or them?
Under the contracted-out R&D rules that apply for accounting periods beginning on or after 1 April 2024, entitlement generally follows whichever company decided to undertake the R&D and bears the commercial risk, which in most commissioning arrangements is the food or drink company rather than the laboratory carrying out the work. The specific contractual arrangement needs checking in each case, since the position can differ depending on who defines the project and bears the risk of failure.
Can we claim for reformulation work carried out by a contractor based outside the UK?
Generally no, since relief for overseas subcontractor and externally provided worker costs was restricted from April 2024 to work carried out within the UK, subject to narrow exceptions where a necessary condition for the work is not available in the UK. This is worth checking before commissioning overseas technical support for a reformulation project you intend to claim on.
What happens if HMRC does not agree that our reformulation project involved genuine technological uncertainty?
HMRC can open a compliance check and, if it concludes the uncertainty was not genuine or was readily resolvable using existing knowledge, can disallow the claim in whole or in part, potentially with penalties if the claim is found to have been made carelessly. Strong contemporaneous technical documentation, prepared at the time the uncertainty was identified rather than reconstructed afterwards, is the most effective protection against this outcome.
Is there a minimum spend needed before a food and drink reformulation project is worth claiming for?
There is no statutory minimum, though the administrative cost of preparing a robust technical narrative and Additional Information Form means very small projects are sometimes not worth claiming individually. It is often more efficient to group genuinely related qualifying activities within a wider development programme into a single, well-evidenced claim rather than pursuing numerous very small ones.
