Learn how Canada’s Accelerated Investment Incentive works, the phase-out rules, and how leasing vs buying affects deductions before 2030.
If you’re buying (or leasing) equipment in Canada, the AII is one of the biggest “timing levers” you can pull to accelerate tax deductions—without changing what you ultimately deduct over the asset’s life.
Here’s the plain-English promise of this guide: by the end, you’ll know (1) whether your next equipment purchase qualifies, (2) how much extra first-year CCA you can claim under the current rules (and what’s being proposed), and (3) how to structure leasing-first so you don’t accidentally lose the tax benefit you’re expecting.
Not tax advice. The AII rules are technical, and the right move depends on your year-end, your taxable income, and how the equipment is actually used. Use this as a planning guide, then confirm with your accountant.
Key point: The AII is a set of rules that can increase your first-year CCA deduction for most depreciable capital assets—meaning you may deduct more upfront and less later.
The CRA explains the core mechanic like this:
Also important: the CRA is explicit that the AII doesn’t increase your total lifetime CCA—it just shifts deductions earlier. (Canada)
Key point: The AII is not “free money,” but it can materially improve after-tax cash flow in the year you place equipment into service.
That matters when you’re trying to balance:
If you’re already thinking leasing-first, start here for a practical baseline on how equipment leases are commonly structured in Canada: equipment leasing in Canada (ultimate guide) (https://www.mehmigroup.com/blogs/equipment-leasing-canada).
Key point: You only claim the enhanced first-year allowance in the first tax year the asset becomes “available for use.” If it arrives late, sits uninstalled, or isn’t ready, your deduction can shift into a later year (and potentially a worse AII multiplier). (Canada)
This is where businesses get surprised. They “bought it in December” but it’s not commissioned until February—so the intended deduction lands in the next fiscal year.
Practical timing checklist (planning, not legal):
If timing matters, structure the deal so delivery/installation dates are clear (especially on leases) and keep your paperwork clean.
Key point: Under the CRA’s current published rules, eligible property must be acquired after Nov 20, 2018 and become available for use before 2028, with a phase-out for property available for use after 2023. (Canada)
Separately, the federal government’s 2024 Fall Economic Statement (FES) proposes to fully re-instate the AII for a period and then phase it out later—creating the “before 2030” planning horizon many advisors are now watching. (Budget Canada)
Source for the “current vs proposed” timeline: the 2024 FES Supplementary Information and CRA’s “What’s new for corporations” page describing the proposal. (Budget Canada)
Key point: For assets normally hit by the half-year rule, AII is effectively “more than removing the half-year rule.” It can increase the base used for first-year CCA.
A simplified way to think about it (common case: declining-balance classes subject to half-year rule):
First-year CCA ≈ CCA rate × (cost ÷ 2)
First-year CCA ≈ CCA rate × (1.5 × cost)
That’s why CRA says it’s “in essence” 3× the normal first-year amount for half-year-rule property. (Canada)
CRA states the enhanced first-year allowance is reduced to 2× the normal first-year amount for half-year-rule property available for use during 2024–2027. (Canada)
If you want to sanity-check the class rates and how CCA generally works, see this explainer: CCA classes in Canada (with calculator) (https://www.mehmigroup.com/blogs/cca-classes-canada-explained-calculator).
Key point: Usually, the party that owns the asset claims CCA (and therefore AII). If you’re a lessee under a typical lease, you generally deduct lease payments, not CCA.
The CRA’s guidance on leasing costs is straightforward: you can generally deduct lease payments incurred in the year for property used in your business. (Canada)
So what does that mean in practice?
If you’re comparing structures, these will help:
Chasing the “biggest first-year deduction” can be a trap if it forces you into the wrong balance sheet decision.
For many growing operators, the best outcome is:
A slightly “less optimal” tax outcome can be worth it if the lease prevents a cash crunch.
If you’re pressure-testing offers, this is a helpful baseline: equipment lease rates in Canada (what drives pricing) (https://www.mehmigroup.com/blogs/equipment-lease-rates-canada).
Key point: Lenders don’t approve deals because of CCA. They approve deals because your file clears risk—especially cash flow resilience.
A classic credit framework is the 5Cs: character, capacity, capital, collateral, and conditions.
Here’s how the AII and “maximize deductions” thinking intersects with underwriting:
If you want a practical way to estimate the payment side while you plan the tax side, use an all-in view: equipment financing cost calculator (Canada) (https://www.mehmigroup.com/blogs/equipment-financing-cost-calculator-canada).
Key point: You don’t need perfect tax modeling to make a good decision—you need directional clarity.
Example: 30% class rate (illustrative).
Then translate deduction to cash impact:
That’s it. Enough to decide whether timing and structure are worth the effort.
Key point: Most “lost AII” stories are really timing + documentation stories.
You only claim the enhanced allowance in the year it becomes available for use. (Canada)
The CRA outlines restrictions and examples showing situations where property can be non-eligible (for example, certain non–arm’s length transactions). (Canada)
A December delivery is not the same thing for:
Lease payments have GST/HST implications and ITCs are handled differently than “buying equipment.” If you’re leasing equipment, read this before you assume anything: GST/HST on equipment leases (Canada) (https://www.mehmigroup.com/blogs/gst-hst-on-equipment-leases-canada).
Key point: Leasing can win on tax simplicity and cash flow stability, even if you could have claimed AII by purchasing.
Typical leasing-first situations:
If you’re sitting on equipment you already own and want to free up cash without losing operational use, sale-leaseback can be the middle path:
Key point: The “best” plan usually combines tax timing with a structure that underwriters can fund cleanly.
Business: Canadian B2B services firm (fast-growing), expanding into a larger facility and upgrading IT + warehouse equipment.
Problem: They wanted the biggest possible deduction, but buying outright would drain cash and weaken their balance sheet right before a busy season.
What they considered:
What they did (leasing-first hybrid):
Outcome (why it worked):
This is the kind of structure Mehmi typically favors: keep cash available, match payments to use, and avoid turning tax planning into a balance sheet mistake.
Key point: Your plan should be built around (1) asset timing, (2) structure (lease vs buy), and (3) proof for both CRA and lenders.
List:
Use a simple rule:
This is where the AII is won or lost. (Canada)
If you’re applying for leasing, you’ll move faster if you already understand what approvals typically require. (If you operate in the GTA, this checklist is a practical benchmark even if you’re elsewhere): Toronto equipment lease approval checklist (https://www.mehmigroup.com/blogs/toronto-equipment-lease-approval-checklist-2025).
If you’re planning a major equipment refresh and want to sanity-check structure + timing (lease vs buy, delivery sequencing, and what underwriters will actually approve), Mehmi can review the deal and help you choose a path that protects cash flow while staying tax-smart.
No. CRA notes the AII does not change the total you can deduct over the asset’s life—it accelerates the first-year deduction and reduces later-year CCA. (Canada)
In most cases, the key trigger is the first tax year the asset becomes available for use—that’s when the enhanced first-year allowance can be claimed. (Canada)
The 2024 Fall Economic Statement proposes reinstating the AII for qualifying property acquired on or after Jan 1, 2025 and available for use before 2030, with a phase-out afterward. CRA summarizes this as proposed changes. (Budget Canada)
Usually, no—because you generally don’t claim CCA on leased equipment. Instead, you typically deduct lease payments for business-use property (subject to specific rules in special cases). (Canada)
With leases, GST/HST is typically charged on periodic payments and ITCs are claimed based on your GST/HST registration and use. Purchases concentrate GST/HST upfront (subject to your ITC eligibility). For a practical overview: https://www.mehmigroup.com/blogs/gst-hst-on-equipment-leases-canada
Lenders care about risk first—capacity and liquidity, not your CCA schedule. A common framework is the 5Cs (character, capacity, capital, collateral, conditions).
