Can a company limited by guarantee claim R&D tax relief?

Yes. A company limited by guarantee is a company for corporation tax purposes and can claim on the same terms as any other, provided it is carrying on a trade and is not a charity or one of the other bodies excluded by name. Having no share capital, having members rather than shareholders, and having an asset lock are all irrelevant to the relief.

Can a company limited by guarantee claim R&D relief?

Why the structure does not matter

The legislation asks whether you are a company within the charge to corporation tax. “Company” for this purpose means any body corporate or unincorporated association. It does not mean a company limited by shares, and nothing in the R&D rules asks about share capital, distributable profits, or who owns the company.

So a company limited by guarantee, a community interest company limited by guarantee or by shares, an industrial and provident society, or a co-operative can all be claimants. What each of them still has to do is meet the ordinary conditions: carry on a trade, spend money on a qualifying project, and have that spending deductible against the trade.

What does stop these companies claiming

Charitable status. Charities are excluded from R&D tax relief by name. A company limited by guarantee that is a registered charity, or that is a charity for tax purposes without being registered, cannot claim. This is the exclusion that catches most non-profit claimants, and it applies however the company is structured underneath.

The distinction to hold onto: a community interest company is not a charity. It has an asset lock and a community purpose, but it is a taxable trading company and it can claim. A great many CICs are told otherwise by accountants who see “non-profit” and stop reading.

No trade. A guarantee company that exists to hold assets, administer membership or receive grants, without carrying on a trade, fails the trade condition for the merged scheme in the same way any other company would. Many membership and industry bodies are in this position: they may be doing genuine development work, and there is no trade for the expenditure to be deductible against.

Nothing to relieve it against. A company with no corporation tax liability and no trading loss to surrender may find the relief has nowhere to go. Under the merged scheme the credit is taxable income and works through a set of steps that can end in a payment, so this is less often fatal than it used to be — but it needs checking rather than assuming.

Grant funding. Non-profit structures are disproportionately grant-funded, and grants raise a separate set of questions about subsidised and contracted-out expenditure that can remove most of a claim. The structure is not the problem; the funding usually is.

Charitable trading subsidiaries

A charity’s wholly-owned trading subsidiary is a separate company and is not itself a charity, so the exclusion does not reach it. It can claim on its own development spending if it meets the ordinary conditions.

The difficulty is not eligibility but funding. Where the charity pays for or directs the work the subsidiary carries out, whether that expenditure is contracted out to the subsidiary or subsidised decides whether there is a claim left. Establish the funding flows before scoping the claim.

Worked example

Illustrative. A community interest company limited by guarantee develops assistive technology hardware. It sells devices to local authorities and to individuals, and it receives an innovation grant covering part of the development cost. It is not a charity. It has 14 staff and makes a small trading loss.

Question	Answer
Is it a company within the charge to corporation tax?	Yes — a CIC is a body corporate and pays corporation tax on its trading profits
Is it an ineligible company?	No — it is not a charity, a higher education institution, a scientific research organisation or a health service body
Is it carrying on a trade?	Yes — it sells devices
Is the development spending deductible against that trade?	Yes, so far as it is revenue expenditure
Is there a claim?	Yes, on the unsubsidised part of the expenditure

The grant is where the work is. It does not disqualify the company and, for accounting periods beginning on or after 1 April 2024, it does not move it into a different scheme either — but the treatment of grant-funded expenditure has to be worked through cost by cost.

Where claims go wrong

Being told a non-profit cannot claim. The commonest failure here is not a rejected claim but a claim never made. If the company is not a charity, start from the assumption that it can claim.
Treating a CIC as a charity. They are different things with different tax consequences, and the R&D exclusion applies only to one of them.
Assuming a charity’s subsidiary is barred. It is not. The obstacle is the funding analysis, and that is worth doing properly rather than declining at the door.
Ignoring the trade condition in a membership body. A guarantee company with subscription income and no trade has a real problem that no amount of good technical narrative fixes.
Leaving the grant analysis to the end. In grant-funded non-profits the grant usually determines the size of the claim. Do it first, so nobody spends three weeks costing a claim that is mostly subsidised.
