For years, the advice on year-end equipment purchases was simple: buy before December 31 and claim a partial first-year deduction. This year, the proposed Productivity Mega Deduction could change that calculation. If enacted as announced, it would let businesses write off the full cost of most new depreciable property in the year it becomes available for use.
That is a significant shift, and it affects how, when and whether you should time a purchase in the next two months. The rules are still proposals, however, and the details matter. Here is what business owners should understand before committing capital.
How equipment is normally deducted
Under the capital cost allowance (CCA) system, a business does not deduct the cost of machinery or equipment all at once. Each asset goes into a prescribed class, and a fixed percentage of the remaining balance is deductible each year on a declining-balance basis. The Department of Finance describes the system the same way: a portion of the cost is deductible each year, at a rate set by the asset’s class.
The result is that a large purchase can take many years to recover for tax purposes. That is why year-end timing has traditionally mattered. A deduction is only available once the property is available for use, so an asset that is not in service by your fiscal year-end generally produces no deduction in that year.
What has changed: from Super-Deduction to Mega Deduction
Budget 2025 introduced the Productivity Super-Deduction, which gives immediate expensing to about 15 per cent of investment in capital assets. It covers items such as manufacturing and processing machinery, clean energy equipment, zero-emission vehicles, data network infrastructure and computers.
On September 15, 2026, the federal government announced the Productivity Mega Deduction at the Canada Investment Summit. It would make immediate expensing permanent and extend it to a much wider range of assets. The government estimates that about two-thirds of investment in capital assets would qualify. Its stated goal is to cut Canada’s marginal effective tax rate on new investment from 13.0 per cent to 6.4 per cent.
Two points deserve emphasis:
- It applies to property acquired on or after September 15, 2026. Purchases already made this fall may qualify.
- It is proposed, not enacted. Draft legislation was released alongside the announcement, but the measure is not yet law. Budget 2026 is scheduled for November 5 and may add detail.
What may qualify, and what may not
In general, the proposal covers capital property subject to the CCA rules that is acquired on or after September 15, 2026. Examples cited by commentators include software, computer equipment and patents. Several categories are carved out, and used property is restricted.
| Category | Proposed treatment |
|---|---|
| Most new machinery, equipment, software and computers | Eligible for 100% deduction in the year available for use |
| Buildings in Classes 1 and 3 | Excluded (manufacturing and processing buildings keep the Super-Deduction) |
| Franchises, licences and goodwill (Classes 14 and 14.1) | Excluded |
| Certain vehicles (Classes 10 and 10.1) | Limited; generally must be assembled in Canada and never used before |
| Used property | Eligible only if neither you nor a non-arm’s-length person owned it before, and it was not acquired on a tax-deferred rollover |
| Anything excluded | Still eligible for the enhanced first-year deduction under the Accelerated Investment Incentive |
Owner-managers should also note a limit for individuals and partnerships with individual members. For them, the deduction cannot create or increase a business loss, so it is limited to income from the business or property where the asset is used.
Timing: “available for use” matters more than the invoice date
The Mega Deduction does not turn a purchase order into a deduction. Immediate expensing allows a full write-off in the year the asset becomes available for use. In general, that means delivered, installed where necessary, and ready to operate, though the tax rules contain specific tests and a time limit that can apply regardless of use.
That has a practical consequence for year-end planning. Under the traditional rules, an asset that slipped into January cost you part of a first-year deduction. Under immediate expensing, it can defer the entire deduction by a year. Before December 31, owners should confirm:
- the equipment will be delivered and operational, not simply ordered or invoiced;
- the purchase date is on or after September 15, 2026;
- your own fiscal year-end, since a business without a December 31 year-end has a different deadline; and
- whether the asset is new, or used in a way that could fail the arm’s-length and rollover conditions.
A bigger deduction is not always a better outcome
Immediate expensing sets the maximum deduction you can claim. It does not require you to claim it, because CCA is discretionary. That flexibility is where planning adds value.
- Do you have income to absorb it? If the deduction exceeds your taxable income, it creates a non-capital loss. Corporations can generally carry those losses back three years and forward twenty, but a loss is not the same as a refund this year.
- Are you using low-rate room? Corporations that qualify for the small business deduction pay a lower rate on their first dollars of active business income. Deducting too much can leave that low-rate room unused. Sometimes the better plan is to claim less now.
- What will your rate look like later? A deduction is worth more in a year of higher income than in a year of lower income.
- Does the purchase make business sense? A tax deferral never justifies buying equipment you do not need. The asset must earn its keep first.
- Do provincial rules follow the federal ones? Confirm how your province treats the measure before you finalize a projection.
Common mistakes to avoid
We see the same errors whenever a new incentive is announced:
- Treating an announcement as law. Until the legislation is enacted, a projection that relies on the Mega Deduction carries risk. Build a fallback using the existing Accelerated Investment Incentive.
- Assuming every asset qualifies. Buildings, franchises, licences and many passenger vehicles are treated differently or excluded.
- Overlooking used equipment. Second-hand assets can fail the prior-ownership and rollover tests, especially in purchases from related parties.
- Buying for the deduction alone. The tax saving is a deferral, not a gain, and it should not drive an unneeded purchase.
- Ignoring the sale of assets later. Fully expensed property has no remaining tax cost, so a future sale can trigger recapture of the deduction.
Year-end checklist
- List planned equipment, software and technology purchases for the next 12 months.
- Confirm each asset’s CCA class and whether it is new or used.
- Confirm delivery and in-service dates against your year-end.
- Project taxable income with and without the full deduction.
- Review the November 5 federal budget for changes to the proposal.
Plan before December 31
Immediate expensing could be one of the most valuable business tax changes in years, but its value depends on what you buy, when it is ready for use, and how much income you have to offset. Reviewing your purchases now leaves time to adjust before year-end.
