How to Stack SR&ED Credits & Government Grants

Most founders treat funding programs like separate worlds, tax credits on one side and grants on the other. In reality, the smartest strategy is building a “funding stack.” Where each program supports a different part of your cost structure and timeline. When done correctly, you can reduce cash burn, extend runway, and still keep momentum on product development and hiring. The key is avoiding double-counting, keeping documentation clean, and planning early so your projects line up with application windows. For innovation-heavy companies, sr&ed tax credits canada often become the base layer of that stack because they reward eligible experimental work already happening inside the business.

1) Understand what stacking really means

Stacking doesn’t mean claiming the same expense twice. It means combining programs in a compliant way, so you’re funding different eligible activities or applying programs to different portions of the same project.

A simple way to think about it:

• Grants can help fund upfront project execution (cash-flow support)
  
  
• SR&ED can help recover a portion of eligible R&D costs after the fact
  
  
• Together, they can create a smoother funding runway
  
  

If your roadmap includes commercialisation and growth activities, pairing SR&ED with government funding for startups can be a strategic advantage, especially when you plan the sequence properly.

2) Build your “funding map” before you apply anywhere

Before you chase any program, create a funding map for the next 6–18 months. This prevents mismatched applications and makes it easier to prove eligibility later.

Your funding map should include:

• Project phases (research, build, test, deploy, scale)
  
  
• The cost categories for each phase (labour, contractors, tools, marketing)
  
  
• Which phase is experimental vs routine development
  
  
• Dates and milestones (important for grant timelines)
  
  

This map makes it much easier to pursue government grants for startups while still protecting your SR&ED file’s worth.

3) Separate expenses so you don’t trigger reductions

The most serious piling error is disorganised accounting. In case you are unable to demonstrate the way in which costs were funded clearly, there is a possibility of having your SR&ED claim cut down or scrutinised.

Best practices that keep you compliant:

• Track grant-funded expenses in separate accounts or cost centers
  
  
• Maintain clear allocation notes (who worked on what and why)
  
  
• Keep contractor scopes tied to specific deliverables
  
  
• Document when grant funding starts/ends and what it covers

The clarity can be used to safeguard sr&ed tax credits canada eligibility and minimizes the chances of claiming the same amount of expenses twice.

4) Time your stack so cash flow stays predictable

Grants are normally received earlier, but SR&ED is normally received later (after filing). This timing is used by a smart stack in order to normalize cash flow.

A common sequence:

• Apply for grants tied to early milestones (build/test/commercialize)
  
  
• Run ongoing documentation habits while the work happens
  
  
• File SR&ED after year-end with clear evidence and costing
  
  
• Reinvest returns into the next development cycle
  
  

For many teams, this approach turns government funding for startups into a repeatable growth system instead of a one-time win.

5) Use one documentation system for everything

Stacking is easier when you use one “source of truth” for project evidence. That means your claim file and your grant reporting should pull from the same project records.

Keep these consistent:

• Project summaries (what changed, what was tested, what worked)
  
  
• Time tracking with project codes
  
  
• Evidence logs (tests, benchmarks, commits, prototypes)
  
  
• Budget tracking aligned to milestones
  
  

This also makes future government grants for startups applications faster because your proof is already organized.

Conclusion

Stacking can be a powerful way to extend runway, but it only works when the rules are respected and the documentation is airtight.
