R&D tax credits can support your innovation, but the process can seem technical and hard to fit around daily work when you are focused on customers and cashflow.

Claiming R&D tax credits can feel like a big task when you already have customers to serve while you closely watch cashflow. The scheme offers valuable support for innovation, yet the process can look technical and strict, so it can be difficult to fit around normal work.
Many businesses delay a claim because they feel unsure about where to start and the level of detail HMRC expects on the corporation tax return. A simple structure helps you turn unstructured details about qualifying projects into a complete claim that you can file with confidence.
Tax rules for R&D are written with strict definitions. This helps HMRC protect the scheme, but it also means the language can feel technical and difficult to apply to your own projects. Small finance teams and owner-managers often do not have spare time to read detailed manuals or cross check every example against their own records.
The claim process also involves several moving parts. It is necessary to identify qualifying projects and gather relevant costs. After that, they must connect people and activities to those projects and explain the technical detail in a way HMRC expects. This work requires input from finance, senior leaders and the technical staff who understand what actually took place.
Consultants who specialise in R&D handle these steps every day, so they know how to turn complex rules into practical actions. Business owners who want to stay in control but avoid a trial and error approach can work with an experienced team, which makes the whole process more manageable.
HMRC wants to see that your company carried out work that meets the definition of research and development for tax purposes when you claim R&D tax credits. The projects must seek a scientific or technological advancement and involve uncertainties that a competent professional could not easily resolve at the outset. The claim also needs to show how the work developed, starting with the original idea, how it developed throughout the trial-and-error stages and ending in a practical solution or in some instances, failure to achieve the solution.
A strong claim sets this out in a structured way. The narrative identifies the business context and describes the technical challenge, also explaining the attempts you made to overcome it. The claim then links eligible costs, such as staff time and consumables, to the relevant activities.
Accuracy matters because HMRC may ask questions about your submission. Clear records reduce follow-up queries and support faster processing of valid claims.
The first practical step when considering a claim for R&D tax credits is to work out which projects were undertaken in the claim period. This means looking back across the financial year and spotting the work that required technical problem solving or experimentation with new methods.
A project list can help, with each entry noting the name of each candidate project, the main technical objective and the people who led the work. Budget codes or internal job numbers can also be linked to this list so that finance data aligns with the technical picture. As you do this, you build a view of where R&D activity sits inside the wider business.
Teams that set up this project list once tend to find future claims much easier. The same structure can carry forward into the next period, so you are not starting from a blank page every year when you plan to claim R&D tax credits.
Once you know which projects belong in scope, you can start to collate costs that relate to the work you plan include in your claim.
Typical areas to review include:
You should then estimate the proportion of each cost that relates to qualifying work, making concise notes that explain your reasoning.
HMRC asks every claimant to provide the same core information. Perfect timesheets for every hour are not required. What matters is that you use a sensible and consistent methodology, supported by enough evidence to show how you calculated the percentages used in your R&D tax credit claim.
Financial data is only one element of a robust claim for R&D tax credits. HMRC also expects a technical explanation that clearly evidences why the work meets their definition of R&D. It should make sense not only to a technical reader and a tax inspector, but also a lay reader so they are able to understand why the project involved genuine technical uncertainty and real learning.
Good records do not need to be complex. Many companies use simple project briefs and design notes, supported by concise summaries of test results. Brief interviews with project leads can fill any gaps and ensure the written report reflects the reality of what happened every day.
Each project narrative identifies the scientific or technological advance and the uncertainties you faced during the period. It also summarises the outcome at the end. This report sits alongside the numbers and helps HMRC understand why you decided to claim R&D tax credits.
Once the costs and technical explanations are complete, you can prepare the claim. This involves filling in the relevant sections of your corporation tax return, attaching the technical report and submitting schedules that show how you calculated the R&D figures.
The figures must match across the return, and the narrative should support and align with the totals you provide. If the descriptions and numbers do not match, HMRC may ask for more information, which can delay the claim.
Specialist advisers often work with clients and their accountants at this stage. They review the calculations, check the project descriptions and make sure each entry appears in the right place. You remain in control of the final numbers, while avoiding the pressure of managing every detail on your own.
Anyone who wants to understand how this structure could work for the next year-end can contact Easy R&D for an initial review and outline plan. A short conversation can confirm where your projects fit the scheme and how much time you could save by passing the claim process to a specialist team.
The time taken to process a claim can vary. HMRC publishes target response times and aims to work within them, yet workloads and queries can affect the length of time it takes to finalise individual cases. The only things within your control are the quality of detail you submit and the speed of any replies you provide if HMRC asks questions.
A well-prepared claim stands a better chance of moving through the system without problems. Consistent figures, clear project descriptions and a solid methodology for allocating costs all help HMRC assess the claim more quickly. Any extra checks HMRC makes are easier to navigate with these elements in place.
Support from a specialist adviser includes guidance on what to expect after you press submit. They can help you respond to questions and explain timelines, so you stay informed. As a result, you understand how your decision to claim R&D tax credits fits into your wider cash flow planning and future development work.
The rules for R&D evolve over time and HMRC continues to refine the way it reviews claims. Keeping abreast of these updates can be hard if R&D is only one small part of your annual workload. A specialist partner can focus on the detail while your internal team concentrates on running projects and managing customers.
Specialist firms invest time in understanding current guidance and the practical effects of changes to the scheme, including real enquiry trends. They use this knowledge to structure claims effectively and to gather the right evidence. Clients benefit from this experience each time they claim R&D tax credits without needing to develop the same level of expertise within their own teams.
Working with a consultant does not take your responsibilities away. Instead, it helps you meet them more confidently. You remain responsible for deciding which projects to include and which costs are appropriate, and any benefit that comes back to the business stays fully under your control.
R&D tax incentives exist to reward innovation, yet the claim process often feels complex for businesses that try to handle it alone. Companies that recognise that pattern in their own organisation do not need to keep putting off this work or guess their way through the rules.
Easy R&D can walk you through the steps. Support covers project planning for your claim and cost gathering, then continues through submission and HMRC follow up. We focus on making each claim as accurate and timely as possible so your organisation can focus on its core work. Ready to claim R&D tax credits?
