What is SR&ED?
Canada's largest tax incentive program providing up to 65% tax credits for research and development activities.
Scientific Research & Experimental Development (SR&ED) is work that must be a systematic investigation or search carried out in a field of science or technology by means of experiment or analysis to achieve one of two purposes:

The "HOW" Test
Work must involve systematic investigation:
- Systematic investigation or search (not just systematic approach)
- Conducted through experimentation or analysis
- In a recognized field of science or technology
- Hypothesis formation and testing methodology
