What supporting documentation do I need to keep?In order to support your SR&ED claim, it is important to maintain evidence that substantiates the SR&ED work performed and expenditures incurred. The CRA stresses the importance of current and accurate documentation to support all aspects of the research project.
If your SR&ED claim is selected for review, you will be asked during the review process to provide this evidence. Generally, the best evidence is that which was generated as the SR&ED was being carried out.
Examples of technical and financial supporting evidence that should be kept:
- Proof of salary paid/payroll records
- Material receipts/invoices
- Project planning documents
- Documents on design of experiments
- Experimentation plan
- Design documents and technical drawings
- Project records, laboratory notebooks
- Design, system architecture and source code (software development)
- Records of trial runs
- Project progress reports
- Minutes of project meetings
- Test protocols, data, results, analysis and conclusions
- Final project report or professional publications
- Photographs, videos
- Prototypes, samples
- Scrap, scrap records
- Contracts, lease agreements
- Records of resources allocated to the project, time sheets, activity records, etc.
- Purchase invoices and proof of payment
- Accounting records
Note: This list is not comprehensive; you should keep any documentation that you feel will support your claim.
