CIRD84000 - R&D tax relief: categories of qualifying expenditure: externally provided workers

FA00/SCH20/PARA8A

Qualifying expenditure on externally provided workers may qualify for R&D tax relief where it is incurred on or after:


  • 27 September 2003 for the SME scheme, and
  • 9 April 2003 for the large company scheme.

Externally provided workers are defined at CIRD84100. This category of qualifying expenditure addresses the situation where a staff provider is contracted to supply external workers. This does not include the recruitment costs of staff provided by employment agencies, nor does it include the situation where the contract is for more than the provision of workers and amounts to subcontracting of a part of the R&D activity. Subcontracting is dealt with at CIRD84200. The expenditure must be for the provision of staff and not for other services. So it does not include payments to self employed consultants CIRD84100.

The legislation is based on the income tax rules for agency workers at Section 44 Income Tax (Earnings and Pensions) Act 2003 which require staffing providers to operate PAYE in relation to individual workers supplied to clients. The main difference is that the externally provided worker rules also apply where the worker is an employee of the staff provider.

Whether or not the worker is an employee of the staff provider, the legislation is based on a tripartite arrangement between the R&D claimant company, the staff provider and the individual worker. If another company is inserted between the staff provider and the worker, for example if the individual has a personal service company that contracts with the staff provider for the supply of his or her services to the R&D company, then the worker will not qualify as an externally provided worker.

The costs of recruitment of staff do not qualify.

The workers must be directly and actively engaged in the R&D, rather than being support staff such as those providing secretarial or administrative services. If the workers are only partly directly and actively engaged on R&D, then a just and reasonable apportionment of qualifying expenditure should be made.

Unconnected staff provider

If the staff provider is not connected to the company then 65% of the expenditure paid to the staff provider for the supply of externally provided workers is potentially eligible to be treated as qualifying expenditure.

The deduction when the company and the staff provider are connected is dealt with at CIRD84050.

The company may jointly elect with the staff provider to be treated as connected. Such an election is irrevocable and applies to all payments under the same contract or arrangement. The election must be made to HMRC in writing within two years from the end of the accounting period in which the contract or arrangement was entered into, (FA00/SCH20/PARA8D). There is no provision for extending this time limit.

FA02/SCH12/PARA17 (d) adopts the same definition of expenditure on externally provided workers for the large company scheme.
