Double Dipping? How to Stack SR&ED with Grants, IRAP & Provincial R&D Incentives

Sophie Tremblay
PhD — Technical Narrative Lead (SR&ED)

Introduction

Many businesses treat SR&ED as standalone. The smarter path is to layer it with grants, IRAP contributions, and provincial credits. But stacking comes with traps: double counting, repayment clauses, and audit scrutiny. Done right, though, you can turbocharge your R&D funding.

Grant vs Credit: Key Differences

Feature Grant / Contribution SR&ED Credit
Timing Upfront / mid-project Post-filing, refund or tax reduction
Documentation Deliverables, milestones Experiments, narrative, logs
Eligible costs Often restricted labour / materials Labour, materials, overheads, (and capital under new proposals)
Risk Some repayable, audit risk from provider CRA audit risk, but more stable if documented

Clean Stacking Principles

  1. Separate cost pools: Don’t claim the same labour or expenditure twice
  2. Attribution by experiment: Map incremental tasks funded by grant vs tasks claimed in SR&ED
  3. Narrative clarity: Clearly label which portion is grant-funded vs credit-claimed
  4. Respect program restrictions: Some grants block overlap or have exclusivity clauses
  5. Record tracking / audit trail: Separate project codes, logs, subaccounts

Example Scenario

A company receives an IRAP grant covering 50% of prototyping labour. They reserve the other 50% of labour and material costs for SR&ED. Then they layer a provincial R&D credit on top of the net base. The narrative clearly delineates funded vs claimed work streams, and logs separate each task’s time and cost.

Pitfalls to Avoid

  • Overclaiming subcontractor work if partially grant-funded
  • Vague narratives that conceal overlap
  • Poor internal cost attribution systems leading to audit adjustments
  • Grant terms that penalize overlapping claims

Implementation Tips

  • Use project codes / cost centers for funded vs creditable work
  • Maintain experiment logs annotated by funding source
  • Reconcile cost schedules with grant claims pre-submission
  • Use internal review checkpoints to spot overlap early

Net Benefit & ROI

Stacked funding can significantly increase your effective subsidy rate. Rather than relying on SR&ED alone, you may combine upfront grants for high-risk phases with SR&ED for mid/late experimentation, and provincial credits for final eligible work.

How GovMoney Can Help

We host a Funding Stack Workshop, assist with carve-out design, simulate net funding scenarios across SR&ED, IRAP, and provincial incentives, and build tracking systems that survive audits.
