HMRC’s R&D advance assurance pilot: a guide for startups

Starting a business is never straightforward, and investing in innovation often adds to the uncertainty. The R&D tax credit scheme can help reduce some of that risk by rewarding startups for investing in R&D. But recently, the scheme has become complex and harder to navigate. To address these concerns, HMRC has launched a limited pilot of a new targeted advance assurance service to give startups more clarity before submitting a claim.

An existing full claim advance assurance scheme has been available since 2015, but take-up has been low. Many found that the eligibility criteria were too restrictive, with only first-time small company claimants able to apply. Many others have faced increased scrutiny from HMRC, which has caused some claims to become stuck in prolonged enquiries. Consequently, some startups that should be claiming are not because they lack confidence about when the business will receive the cash back. The targeted pilot is HMRC’s attempt to address this confidence gap and provide better certainty about when you will receive support from your claim.

How the pilot works

The targeted advance assurance pilot allows any SME planning to make an R&D tax relief claim to approach HMRC ahead of submission and seek assurance on four specific issues:

1. Whether the project meets the definition of R&D for tax purposes
2. Whether their overseas expenditure qualifies
3. Which party is entitled to claim relief on contracted-out expenditure
4. Whether the business qualifies for exemption from the PAYE/NICs cap

These four issues were selected in direct response to consultation feedback, which identified them as among the most common sources of uncertainty and dispute for businesses making R&D claims. Rather than seeking HMRC’s assurance on their entire claim, startups can now ask targeted questions and receive an answer with a quick response time (40 days). Assurance, if granted, means HMRC commits not to open a compliance check on that specific aspect of the claim, provided the facts presented in the application accurately reflect the activities carried out.

What this means for startups

The targeted pilot represents a real and tangible improvement. The most significant of the four issues that startups face is testing whether a project meets the definition of R&D for tax purposes. This is the question that underlies most R&D enquiries. If a business can obtain HMRC’s view on whether a project qualifies before it submits its claim, it can plan with greater confidence, reduce the risk of a costly dispute, and make better-informed decisions about future cashflows.

The quality of an application therefore matters enormously. Assurance covers only what you tell HMRC, and it is conditional on the facts matching the final claim. A poorly prepared application that does not accurately describe the qualifying activity, or a rushed speculative application, may end up failing assurance and will likely lead to any subsequent claim be flagged for review by HMRC.

Where the pilot falls short

The pilot is a step forward, but there are limitations that are worth understanding clearly.

Any submission only covers four issues, and businesses seeking certainty on any other common issues will not find support from the pilot. Assurance is provided on a project-by-project basis, not at the full claim level. A business that obtains assurance that its project meets the definition of R&D can still face a compliance check on the costs it has included, the way it has calculated the credit, or whether it has correctly applied the rules. Equally, if one project has been tested, HMRC could still ask questions about other projects included within the claim. The targeted nature of the pilot, which is its strength, is also its constraint.

The pilot has been set up as a test, not a permanent service. If the scheme is successful, it will very likely be available in the same form in future years, or if the pilot highlights limitations it might be extended or broadened to meet demand. Startups should keep a close eye on HMRC updates over the coming year to plan for future claims.

What business owners should be aware of

If you are considering using the targeted pilot, there are several practical points worth working through before you submit.

Identify the right issue. The pilot covers four specific questions; you can only seek assurance on two of them per submission and only make two submission per accounting period. Therefore, consider carefully which aspect of your claim carries the greatest uncertainty or risk and focus your application there. Using the pilot on a settled point adds no value and may delay engagement with the issue that matters most.

Do not treat assurance as a substitute for a well-prepared claim. The pilot reduces the risk of a challenge on the assured issue; it does not remove the need to prepare the claim accurately and completely. Both are necessary.

Poker strategy for startups

For businesses making their first R&D tax relief claim with a turnover below £2 million, the existing advance assurance scheme remains available and may be a better option in some circumstances. Unlike the targeted pilot, the existing scheme offers protection across the whole claim rather than a single issue. For a first-time claimant with a relatively straightforward claim and limited appetite for any compliance risk, that broader coverage may be more valuable than focused assurance on one specific point.

HMRC has made clear that both assurance offerings will run in parallel during the pilot period, so it is likely that it expects to see an increase in full assurance applications as startups become more familiar with what support is available.

HMRC’s role in supporting innovation

The targeted pilot reflects something important: HMRC is listening to businesses. Feedback indicated that the existing assurance offer was too narrow to fulfil its purpose, and the willingness to respond to feedback is welcome.

But what is on offer is still a pilot covering a narrow slice of issues. It has explicitly been framed as a test and is not yet the structural solution that many startup businesses were requesting. Investing in innovation requires confidence, particularly confidence that support such as R&D tax credits will be paid out in a reasonable time. Many businesses are still making R&D investment decisions without that confidence, so hopefully pilot will help ease these concerns and ensure that the UK remains a great place to build your startup.

The pilot is a good beginning. Whether it becomes something more useful depends on what HMRC does with what it learns.
