How important is it to have created and retained supporting evidence and documentation to support the claims?
Claims that are submitted with little or poor supporting documentation run the risk of being substantially reduced or even disallowed completely.
Since 2012 CRA’s program review and administration policies have undergone a substantial change. There is now a much greater requirement for the claimant to be able to demonstrate that work on the project was undertaken as part of a “systematic investigation or search”.
The ability to capture (and provide) contemporaneous documents cannot be overstated.
It is important that the Scientific/Technological Objectives, Knowledge/Technology base, Advancements and Uncertainties be documented as soon as possible to show when you identified that there were significant issues that required you to undertake the SR&ED efforts. This helps to establish the starting dates and explain why any existing solution/knowledge was unsuitable/insufficient for your specific needs. Records should also be kept of research, plans, work, testing and analysis, hypotheses/designs/components/approach changes as the project progresses to demonstrate that your efforts were undertaken in a systematic, planned manner.
