What Stacking Actually Adds Up To

Example one: a natural health product manufacturer in Quebec

Reformulation work, one fiscal year

Twelve employees, four of them on development. Private Canadian corporation, December year end.

The company spent the year stabilizing an active ingredient that kept degrading before its shelf-life target. Four staff worked on it part-time, an external laboratory ran analytical testing, and several trial batches were consumed. They also received an NRC IRAP contribution toward the salaries, hired a co-op student, and bought a bench-scale mixer.

The spending	Amount
Salaries on development work	$300,000
Arm's-length Canadian testing laboratory	$50,000
Materials consumed in trial batches	$20,000
New development equipment	$60,000

What arrives, and in what order	Amount
NRC IRAP contribution toward technical salariesNon-repayable, agreed before the work began	$75,000
Student placement subsidy50% of the student's wages, capped	$5,000
Quebec C3i on the new equipment15% in Montreal, refundable, on cost above the $12,500 threshold	$7,125
Quebec CRIC30% of salaries and half the laboratory contract, after deducting the assistance received and the per-employee exclusion threshold	$59,700
Federal SR&ED at 35%On salaries plus 55% proxy overhead plus 80% of the contract plus materials, reduced by the assistance received and by the Quebec credit	$134,855
Total recovered in the year	$281,680

What coordination was worth. Had the company skipped IRAP and the student subsidy and claimed only its credits, it would have recovered about $245,000, because a smaller assistance deduction leaves a larger credit base. Taking the $80,000 of grants therefore added roughly $37,000 net, not $80,000. That is the number nobody quotes, and it is still the right decision: cash arriving during the year is worth more than a credit arriving after filing, and the grants are what made the extra testing affordable in the first place.

Example two: a software company in Ontario

Rebuilding a data pipeline that would not scale

Nine employees. Private Canadian corporation, no grant funding taken.

The team hit a performance ceiling that standard architectures could not clear, and spent most of the year designing and testing alternatives, several of which failed. No grant was applied for; the only external money is a student subsidy. This is the plainest case in the system, and it shows what a well-prepared claim alone is worth.

The claim base	Amount
Salaries on eligible development	$500,000
Proxy overhead at 55% of salariesNo receipts required	$275,000
Arm's-length Canadian contractors at 80% of $100,000	$80,000
Expenditure base	$855,000
Less the student wage subsidy received	($5,000)

What arrives	Amount
Ontario Innovation Tax Credit at 8%Refundable, on up to $3 million of expenditure	$68,000
Ontario Research and Development Tax Credit at 3.5%Non-refundable: it reduces Ontario tax payable rather than paying cash	$29,750
Federal SR&ED at 35%On the base after the subsidy and the Ontario credits are deducted	$263,288
Student placement subsidy	$5,000
Total recovered in the year	$366,038

Read the refundable line carefully. Roughly $336,000 of this is cash regardless of whether the company is profitable. The Ontario 3.5% credit is not; it waits for tax payable. Any advisor quoting you a single combined percentage without separating refundable from non-refundable is quoting a number you may not receive this year.

Example three: a manufacturer buying equipment in Ontario

A production line that would not hold tolerance

Forty employees. Capital investment plus process development plus operator training.

The company bought a new line, and getting it to hold tolerance on its own material turned into months of systematic trials. Three operators were trained by an external provider. Three different programs apply here, to three different costs, and none of them reduces the others.

What arrives	Amount
Ontario Made Manufacturing Investment Tax Credit15% refundable on $1.2 million of eligible machinery and building costs	$180,000
Ontario workforce training grantUp to $10,000 per trainee, with the employer covering about one sixth of the cost at this size	$30,000
Ontario credits on the process development work8% refundable plus 3.5% non-refundable on a $272,500 base of salaries, proxy, and materials	$31,338
Federal SR&ED at 35% on the process developmentOn the same base, after the two Ontario credits are deducted	$84,407
Total recovered in the year	$325,744

The equipment credit and the research credit do not collide. The manufacturing credit is claimed on the capital cost of the line; the research credit is claimed on the labour and materials spent making it work. Companies routinely claim the first and never think to claim the second, or claim the second and miss the first because nobody asked what they bought.

The rules that decide the total

Every one of these examples turns on four rules. They are not complicated, but each of them costs real money when it is discovered after the fact rather than planned for.

One. Government assistance reduces the research credit base, project by project. A grant received for one project cannot reduce another project's expenditures. This is why a grant is worth taking and also why it is worth timing: the reduction bites when the assistance is received, is receivable, or can reasonably be expected.

Two. Two federal wage subsidies cannot fund the same salary. A student placement subsidy and a federal research award cannot both sit on the same person for the same period, though two different people on two different programs is perfectly fine. Undisclosed overlap is the single most common cause of a clawback.

Three. One capital credit per asset. An asset attracts one clean economy or manufacturing credit, not several, though a project made up of different property types can attract more than one. In Quebec, the research credit and the investment credit cannot both be claimed on the same property.

Four. The provincial credit reduces the federal base. Combined recovery is never the sum of the headline rates, and the province you operate in changes the answer by ten cents on the dollar or more. It belongs in the plan from the first conversation.

A fifth rule is not about stacking at all, but it ends more claims than the other four combined: the research credit must be filed within eighteen months of the fiscal year end, with no extensions.

What this means for your own numbers

Model the combination before you apply for anything. The order in which grants and credits are claimed changes the total, and once a grant is received the arithmetic is fixed.
Separate cash from tax relief. Refundable credits arrive whether or not you are profitable. Non-refundable credits wait. A funding plan that ignores the difference is a cash-flow problem in disguise.
Ask what you bought, not only what you built. Equipment credits and research credits sit on different costs, and most companies find one and miss the other.
Do not let a grant application delay a filing. The eighteen-month clock does not pause for anything.

The figures above are illustrations built from published program rates, not quotes. Your own total depends on your province, your corporate structure, how much of your work genuinely qualifies, and what assistance you have already received. Working that out is the first conversation.

What would your own stack come to?

Bring us a year of spending and we will model it: which programs apply, in what order, and what lands as cash rather than tax relief. If the answer is that there is nothing worth pursuing, you will hear that first.
