IRAP is the largest source of direct R&D funding for Canadian small and medium businesses, and the least predictable to apply for. It is also government assistance, which means every dollar you receive reduces your SR&ED claim. Most guides skip that part.

Almost every Canadian company that does real R&D eventually hears the same two words in the same sentence: SR&ED and IRAP. They are usually described as complementary, and they are. What is rarely explained is that they are also connected, and not in your favour. An IRAP contribution is government assistance, and government assistance reduces a SR&ED claim dollar for dollar.
That does not make IRAP a bad idea. In almost every case it is still worth taking. But the decision looks different once you can see both numbers at once, and the sequencing of the two is a decision, not an accident.
NRC does not publish a maximum contribution, a cost-share percentage, or an intake deadline. Any guide quoting exact percentages is describing observed practice, not published policy. That distinction matters when you are budgeting.
IRAP is a non-repayable contribution toward the cost of a technical project, delivered through an assigned Industrial Technology Advisor. You spend the money first, then claim it back monthly against receipts.
Three things it is not, each of which sends applications to the wrong place:
That last one catches people. IRAP funds work going forward from approval. Costs incurred before the agreement is in place are generally not claimable, which means the instinct to start the work and sort out the funding later is the most expensive instinct in the process.
There is no application form. You cannot submit a proposal on your own initiative, and no amount of proposal-writing skill substitutes for the step that precedes it.
The process starts with a phone call. If you clear the initial screen, you are referred to an Industrial Technology Advisor, who meets you, forms a view of your business, and decides whether to invite a proposal. The invitation is the real gate. Everything after it is documentation.
End to end, from first call to first reimbursement, several months is normal. Companies that need money this quarter are usually looking at the wrong instrument.
Refusals are less common than stalls. The patterns repeat:
This is the section that matters if you are claiming both, and it is the one most commonly handled badly, because it sits between the grant advisor and the tax preparer and neither of them owns it.
Government assistance reduces qualified SR&ED expenditures dollar for dollar. An IRAP contribution is government assistance. So the same salary cannot be fully funded by IRAP and fully claimed for SR&ED: the claim is reduced by what you received.
Here is what it costs, on a straightforward set of numbers. A CCPC with $500,000 of eligible salary, claiming under the proxy method, receives a $150,000 IRAP contribution toward that same work.
| Without IRAP | With a $150,000 contribution | |
|---|---|---|
| Eligible salary | $500,000 | $500,000 |
| Proxy overhead at 55% | $275,000 | $275,000 |
| Pool before assistance | $775,000 | $775,000 |
| Less government assistance | — | −$150,000 |
| Qualified expenditures | $775,000 | $625,000 |
| Federal credit at 35% | $271,250 | $218,750 |
The federal credit falls by $52,500. So the $150,000 contribution is worth about $97,500 net at the federal level, before the provincial credit is counted, and the provincial credit is generally reduced by the same assistance. Call it somewhere near sixty-five cents on the dollar rather than a hundred.
Which is still a good trade. Ninety-seven thousand dollars you did not have is ninety-seven thousand dollars. The point is not that IRAP is bad. The point is that anyone presenting IRAP as free money on top of a full SR&ED claim has either not done the arithmetic or is not telling you.
Three practical rules, in order of how much money they move:
It is worth pursuing if you are incorporated and profit-oriented, under 500 employees, have a defined technical project with real uncertainty, can fund the work while waiting for reimbursement, and can describe who buys the result.
It is probably the wrong instrument if you need money this quarter, if the work has already been done, if the project is really an equipment purchase, or if you are pre-revenue with no commercial path described. In those cases the regional development agencies, the provincial programmes, or SR&ED on its own are usually the better route, and there is no penalty for asking which before you spend three months on the wrong one.
If you have an IRAP contribution in place, or are about to apply for one, the interaction with your SR&ED claim is worth half an hour before the budget is fixed. That is when the decisions are still available.
