    R&D tax credit accountants

    R&D tax credit claims that hold up to HMRC scrutiny, on a fixed fee

    Chartered accountants find the qualifying technical work, calculate the credit, prepare the HMRC forms and support the claim through any enquiry. The fee is fixed and never a percentage of the claim.

    Definition of the work

    A claim connects technical uncertainty to qualifying expenditure

    Qualifying work is not limited to laboratories. It arises where a project seeks an advance in science or technology and a competent professional cannot readily resolve the uncertainty involved.

    We test the activities, trace the related costs and prepare a specific narrative that can stand up to HMRC scrutiny. We then file the claim notification where it is needed and submit the additional information form before the Company Tax Return.

    Current estimate

    An estimate from the figures you entered, for accounting periods beginning on or after 1 April 2024. The credit depends on which costs qualify and on your wider tax position. It is confirmed only by a prepared claim.

    We turn this estimate into a claim HMRC can check. We test the projects, confirm the qualifying costs and submit the forms in the right order. For a fixed fee, request a quote. If you only needed the number, you have it.

    The rules since April 2024

    Two schemes and two filings that decide whether a claim stands

    Merged scheme: a 20% expenditure credit

    For accounting periods beginning on or after 1 April 2024 most companies claim under the merged scheme. The credit is 20% of qualifying R&D expenditure. It is taxable as trading income, so the benefit kept after Corporation Tax is lower than the headline credit.

    ERIS: extra support for loss-making, R&D-intensive SMEs

    A loss-making SME whose relevant R&D expenditure is at least 30% of its total expenditure can claim enhanced R&D intensive support instead. It deducts an extra 86% of its qualifying costs and can surrender the loss for a payable credit worth up to 14.5% of the surrenderable loss. A company that met the condition in its last 12-month accounting period and made a valid SME or ERIS claim for it can still claim.

    Claim notification: tell HMRC first

    A company claiming for the first time, or one that has not claimed in the previous three years, must send a claim notification within six months of the end of the period of account. Without it the claim is invalid.

    Additional information form: before the return

    Every new claim needs an additional information form describing the projects and the qualifying costs. It must reach HMRC before or on the same day as the Company Tax Return. If the return arrives first the claim is rejected.

    Questions

    R&D tax credit questions, answered

    What counts as R&D for tax purposes?

    A project counts when it seeks an advance in overall knowledge or capability in a field of science or technology, not just in your own company's knowledge. The qualifying activities are those that directly contribute to resolving a scientific or technological uncertainty: one that a competent professional working in the field cannot readily resolve. Work in the arts, humanities and social sciences, including economics, does not qualify.

    How is an R&D claim calculated?

    We identify the qualifying costs of each R&D project. These include staff, externally provided workers, contractors, consumables, software, data licences and cloud computing. Under the merged scheme the credit is 20% of that qualifying expenditure and is taxable as trading income. Contracted R&D carried out abroad generally cannot be claimed.

    What is the additional information form?

    Every new R&D claim needs an additional information form. It sets out the baseline knowledge, the advance sought, the uncertainties and how the work set out to resolve them for each project, along with the qualifying costs. It must be submitted before or on the same day as the Company Tax Return. If the return reaches HMRC first the claim is rejected, so we submit the form first.

    Do I need to tell HMRC before I claim?

    Yes, if the company is claiming for the first time or has not claimed within the previous three years. The claim notification must reach HMRC within six months of the end of the period of account the claim covers. If it is missed the claim is invalid. The rule applies to accounting periods beginning on or after 1 April 2023.

    Should I claim under the merged scheme or ERIS?

    For accounting periods beginning on or after 1 April 2024 most companies claim the merged scheme credit of 20% of qualifying costs. ERIS is for loss-making SMEs whose relevant R&D expenditure is at least 30% of total expenditure. It gives an extra 86% deduction and a payable credit worth up to 14.5% of the surrenderable loss. A company that falls below 30% can still claim ERIS if it met the condition in its last 12-month accounting period and made a valid SME or ERIS claim for that period. We test which applies before the claim is prepared.

    What does an R&D claim cost?

    A fixed fee based on qualifying spend, from £1,500, agreed before any work starts. The fee is never a percentage of the claim, so what we charge does not rise with the size of your credit.
