The accounting treatment of R&D tax credits changed character with the merged scheme, and the change is not cosmetic. The old SME relief worked as an extra deduction in the tax computation and appeared, if anywhere, in the tax line. An expenditure credit is taxable income recognised in operating profit, which means the same underlying claim can now improve a company's reported operating result rather than only its tax charge.
The two mechanisms produce two treatments
Under the SME scheme a company deducts an extra 86% of its qualifying costs from trading profit for tax purposes, on top of the normal 100%, making a total 186% deduction. That is a tax computation adjustment: nothing appears in the accounts except a lower tax charge, or a payable credit worth up to 14.5% of the surrenderable loss where the intensity condition is met. An expenditure credit works differently: it is a credit recognised as income, itself taxable, and shown above the tax line.
When to recognise it
The ordinary answer is in the period the qualifying expenditure was incurred, on the basis that the entitlement arises from the spending rather than from the claim being accepted. That requires the company to be reasonably certain of the amount, which in practice means the claim has been prepared or is being prepared on a basis the company can support. A company that recognises a credit and then has the claim reduced on enquiry restates, which is one more reason for the underlying analysis to be conservative.
The presentation question
Where the credit is taxable income, showing it in operating profit changes reported margins and can change covenant calculations, bonus schemes and valuation multiples that key off EBITDA. That is a real consequence of a tax decision and it belongs in the conversation with whoever prepares the accounts before the first claim rather than after it. This site does not advise on the presentation; the point here is that it is a decision rather than a mechanical entry.
Questions people ask about accounting for r&d tax credit
Where does an R&D tax credit appear in the accounts?
An expenditure credit is recognised as taxable income above the tax line, affecting operating profit. The older SME enhanced deduction was a tax computation adjustment and appeared only in the tax charge.
When should the credit be recognised?
Ordinarily in the period the qualifying expenditure was incurred, provided the company is reasonably certain of the amount, rather than when HMRC accepts the claim.
Is the credit itself taxable?
An expenditure credit is taxable income. The enhanced deduction under the SME scheme was not income at all; it reduced taxable profit directly.
