Calculation of the payable tax credit for accounting periods spanning 1 April 2023. 

Corporation tax is assessed and charged by reference to accounting periods. Company profits arising in an accounting period are apportioned between the financial years (FY) in which the accounting period falls. S8(5) CTA09 requires that the profits of an accounting period must be apportioned between financial years by reference to the number of days in the period. 

Relief on qualifying expenditure may only be calculated at the rate which applied for the FY in which the expenditure was incurred. Where, for example, expenditure which was taken to the balance sheet in one accounting period and then amortised or impaired to the profit & loss account in a later accounting period is the subject of a claim, relief may only be claimed at the rate which applied when the expenditure was incurred. 

The folowing example assumes that all qualifying expenditure was incurred and taken to the profit & loss account in the same accounting period. 

Step 1 

Identify qualifying R&D expenditure, on the basis of when it was incurred, between FY 2022 and FY2023 

Apply the relevant rate of relief (130% or 86%) to the qualifying expenditure to calculate: - 

• the relief which the company may claim and 

• the sum of relief and qualifying expenditureÌýÌý

for FYs 2022 & 2023. 

Step 2 

The tax profit/loss for the whole accounting period is calculated, deducting the relief calculated above. 

Step 3 

 Where the company has made a loss for the accounting period this should be apportioned by reference to the number of days in each financial year. 

Step 4 

Calculate the surrenderable loss and payable tax credit for FY 2022 using the rate of 14.5% 

Step 5 

Calculate the surrenderable loss and payable tax credit for FY 2023 using the rate of 10%ÌýÌý

For the accounting period ended 31 December 2023 Company A incurred the following qualifying expenditure: 

• FY 2022 (1/1/2023 to 31/3/2023) £25,000
