Your status for research and development (R&D) tax credit purposes can change as your staff headcount, turnover, and gross assets fluctuate. This determines whether you fall into the SME R&D tax credit scheme or the research and development expenditure credit (RDEC) scheme.
What happens when my business crosses these thresholds?
Businesses are always evolving. Some SMEs will eventually outgrow these limits. Conversely, a large company may find itself falling below them: it may, for example, reduce the size of its workforce, or become independent from a group of companies.
Where these changes are organic in nature your company’s status should not change until the conditions are met for two consecutive years. This is known as the ‘year of grace’. It means that in the accounting period in which the thresholds are first crossed, you retain your existing status.
There is an exception to this rule: if an SME is acquired by a large company or group, then the year-of-grace provision is suspended. The SME becomes a large company in the accounting period of acquisition. This applies for the whole period, not just from the date of acquisition.
This is an especially important consideration in sectors with high merger and acquisition activity where there are likely to be multiple different scenarios. The facts of each case will determine whether the year of grace will apply.
What are the effects of changing status?
Changing status from an SME to a large company or vice-versa will change the overall R&D tax credit benefit you receive. The R&D tax credit rate differs between the SME R&D tax credit scheme and the RDEC scheme.
There are also other differences between the two schemes, including the types of expenditure you are allowed to include in your claim, as well as the mechanism for relief. However, for accounting periods beginning on or after 1 April 2024, companies of all sizes will claim under a merged scheme, with the exception of those loss-making SMEs eligible for Enhanced R&D Intensive Support (ERIS).
