When code qualifies for SR&ED

Software development qualifies for SR&ED when it involves systematic investigation of technological uncertainty. The key is the investigation, not the result. Code that was built through experimentation, failed approaches, and iterative refinement is eligible.

  • Investigating a performance problem that required understanding runtime behavior beyond documentation
  • Developing a novel algorithm because existing approaches couldn't meet your specific requirements
  • Resolving a fundamental conflict between technical requirements where no standard solution existed
  • Building a platform that required solving interoperability problems that standard tools couldn't address
  • Systematic investigation of ML model behavior for a domain without established benchmarks

When code doesn't qualify

Routine software development does not qualify for SR&ED. The distinction between investigation and implementation is the key eligibility criterion.

  • CRUD applications using documented frameworks and APIs
  • Standard integrations where the third party provides documentation and SDKs
  • UI/UX work without underlying technical uncertainty
  • Applying a well-documented technique your team simply hadn't used before
  • Configuration tuning within documented parameter ranges

Novel-to-your-team is not the standard. If the approach was documented in a paper, available in a maintained library, or covered by vendor support, it doesn't matter that your team hadn't done it before.
