Definition of R&D for tax purposes

tiemadmin • 1 May 2025

When claiming tax relief or capital allowances on R&D, it’s crucial to ensure activities meet strict statutory definitions. Understanding Section 437 ITA and DTI guidelines is key to securing legitimate tax benefits and avoiding costly mistakes.

An activity is generally considered as R&D if it meets two key criteria:

  1. It is recognised as R&D under standard accounting practice; and
  2. It satisfies the specific conditions set out in the Department of Trade and Industry (DTI) guidelines.

In addition, the definition of R&D for Capital Allowances purposes includes oil and gas exploration and appraisal activities. These are defined as operations conducted with the objective of:

  • Searching for petroleum within a defined area; or
  • ascertaining the characteristics, extent, or reserves of a petroleum-bearing area in order to assess the commercial viability of extraction.

The legislation also allows for the definition of R&D to be further clarified or restricted by secondary regulations made under ITA/S1006. These regulations may either designate certain activities as qualifying R&D or exclude specific activities from being treated as such.

For the purposes of Research and Development Allowances (RDA), any activity defined as R&D under ITA/S1006 regulations must be treated accordingly. Conversely, if an activity is specifically excluded by regulation, it must not be considered R&D for RDA claims.
