What are SR&ED Field of Science Codes?
SR&ED Field of Science Codes are specific classifications assigned to various areas of research and development activities. These codes serve to establish the type of research work that is being carried out, ensuring that it aligns with the criteria outlined by the Canada Revenue Agency (CRA) for SR&ED eligibility. In essence, they provide a framework within which researchers can classify their projects effectively.
The codes are utilized by companies to specify the scientific disciplines involved in their SR&ED claims. By associating their work with appropriate field codes, businesses can demonstrate that their projects qualify for funding and tax credits under the SR&ED program. This not only aids in securing financial support but also enhances the credibility of the research being conducted, as it is recognized within a formalized system.
