Should I Buy the Equipment Before Year-End? The CCA Timing Rules That Actually Decide It (2026)

If you are weighing whether to buy equipment before year end, the CCA rules in Canada decide the answer, and they do not decide it the way most people assume. The question is not whether you can get an invoice dated December 31. It is whether the asset is available for use, how much of a first-year claim the half-year rule leaves you, and — the part almost nobody runs — what the resulting deduction is actually worth in dollars against an 11.2% tax rate.

The short version: a capital cost allowance claim is a timing benefit, not a discount on the purchase price. Insight Accounting CPA writes this one plainly because the arithmetic is unflattering and the arithmetic is the point. A deduction at 11.2% returns about eleven cents on the dollar, and accelerating it by a year is worth the time value of those eleven cents — which is rarely a reason to buy something you did not otherwise need.

Does the purchase even qualify this year?

This is the step readers skip, and it is the gate. Subsection 13(26) of the Income Tax Act provides that no amount is included in the undepreciated capital cost of a class before the time the property is considered to have become available for use. An asset bought on December 28 and still crated in the loading bay in January is generally not available for use, and no CCA is claimable for that year — whatever the invoice says.

The timing tests are in subsections 13(27) and 13(28). For property other than a building, 13(27) treats the asset as available for use at the earliest of a set of moments, which include the time it is first used to earn income, and the time it has been delivered and is capable of being used to produce a commercially saleable product or perform a commercially saleable service. There is also a rolling-year rule that deems the property available for use at the start of a later taxation year even if none of the other tests has been met.

Buildings have their own test in 13(28), keyed to the point at which all or substantially all of the building is first used for the purpose for which it was acquired, or construction is complete. A renovation, alteration or addition to a building is treated as a separate building for this purpose.

Two practical consequences for a December purchase:

• Delivery plus capability is usually the operative test for machinery and equipment. Equipment that arrives and could be run, had you needed to run it, is in a much stronger position than equipment still in transit.
• Installation and commissioning matter. A machine that cannot be operated until a contractor completes an electrical tie-in in February is not capable of producing a commercially saleable product in December. If the deduction is the reason for the purchase, the install schedule is part of the decision, not an afterthought.

How much of a first-year claim do I actually get?

Assuming the asset is available for use, the next constraint is the half-year rule in subsection 1100(2) of the Income Tax Regulations. “Half the normal rate” is the usual plain-English shorthand, and it is close enough for planning, but the mechanics are worth understanding because they change the answer in two situations.

What the regulation actually does is adjust the undepreciated capital cost of the class by a formula that subtracts half of a quantity defined as additions in the year minus dispositions in the year. Two things follow:

• It operates on net additions. If you add a $50,000 machine and dispose of $20,000 of assets from the same class in the same year, the half-year restriction applies to the $30,000 net figure, not the $50,000.
• Property qualifying for an enhanced first-year allowance is carved out of that quantity entirely. Where an enhanced first-year regime applies, the half-year restriction does not bite in the ordinary way. This is the single most common error in secondary summaries of this area — applying the half-year haircut to property that is not subject to it, or the reverse.

The ordinary class rates matter too, because they set the ceiling. CRA’s own classes of depreciable property page gives Class 8 a rate of 20%, Class 10 and Class 10.1 a rate of 30%, and Class 50 a rate of 55%. Class 53 carries a 50% rate but is limited to eligible machinery and equipment acquired after 2015 and before 2026 — so for a purchase made in 2026 it is closed, and the correct class has to be determined on the facts rather than assumed.

One figure we will not publish: CRA’s classes page sets out the Class 10.1 capital cost ceiling for a passenger vehicle acquired in 2025 at $38,000 before tax, with earlier years listed back to $30,000, but it publishes no 2026 ceiling at the time of writing. If you are buying a passenger vehicle before this year-end, the ceiling is a number to confirm with your CPA against the current source, not one to take from an article.

Which enhanced first-year rules are actually in force right now?

This is where a December 2026 purchase decision gets genuinely awkward, and where stating the enactment stage of each rule is not pedantry but the whole job. Three regimes are in play and they are at three different stages.

1. The original Accelerated Investment Incentive is closed to new purchases. The defining provision in Regulation 1104(4) describes accelerated investment incentive property as property acquired after November 20, 2018 and before 2025. A 2026 purchase cannot be AIIP.

2. A successor regime for property acquired after 2024 appears in the consolidated regulations. Regulation 1104(4.01) defines reaccelerated investment incentive property as property acquired after 2024 that becomes available for use before 2034, and Regulation 1100(2) provides an enhanced first-year factor for such property that is available for use before 2030, declining thereafter. The consolidation we read was current to September 21, 2026 and the provisions carried no not-in-force marking.

   But note a real discrepancy, because it affects what you should rely on. CRA’s own classes-of-depreciable-property page, last modified August 31, 2026, still refers to the reaccelerated investment incentive as a proposed change. The consolidated regulation and the administrative guidance do not currently agree. We are therefore describing this regime qualitatively and declining to publish a phase-down percentage schedule — the stage and the numbers both need confirming against the source on the day you file, not on the day you read this.

3. The Productivity Mega Deduction is a draft proposal, not law. The 100% first-year write-off announced for property acquired on or after September 15, 2026 sits in draft legislative proposals released that day. It has not been enacted and has not received Royal Assent. Insight Accounting CPA covers it in detail, including the acquisition-date test and the exclusions, in our analysis of what Ontario owner-managers must check before signing the next equipment purchase order. Do not plan a purchase on the assumption it will pass in the form announced.

The honest summary is that the first-year claim on a machine bought in December 2026 depends on which of these regimes ultimately applies to it, and that at least one of them is not yet law. That uncertainty is an argument for documenting the available-for-use date carefully — which costs nothing and preserves every option — and against treating any particular headline percentage as bankable.

What is the deduction actually worth in dollars?

Here is the arithmetic that should drive the decision, and it is the section most content on this subject leaves out. Take an Ontario Canadian-controlled private corporation with active business income comfortably inside the $500,000 business limit, buying a $60,000 Class 8 machine. The combined federal and Ontario small-business rate is 11.2% — 9% federal plus Ontario’s 2.2%, in force for days in a taxation year after June 30, 2026 under Bill 97, which received Royal Assent and is now S.O. 2026 c. 2.

First-year treatment	First-year CCA	Tax deferred at 11.2%
Ordinary half-year rule (20% rate, halved)	$6,000	$672
Full 20% with no half-year restriction	$12,000	$1,344
Hypothetical 100% first-year write-off	$60,000	$6,720

Now the part that matters. None of those figures is a saving. They are deferrals. Over the life of the asset you will deduct the whole $60,000 capital cost either way, so the total tax relief is $6,720 under every scenario in that table. What the first-year rules change is when you get it. The real economic value of accelerating the claim is the time value of money on the amount brought forward — for the first row against the third, the use of roughly $6,000 of tax a year or two earlier than you otherwise would have had it.

Against a $60,000 cash outlay, and an operating line priced off prime, that is a modest benefit. It is a genuine benefit, and on a large capital programme it is worth real money. It is not a reason to buy a machine you do not need, and any supplier telling you the purchase is “paid for by the tax saving” is describing a transaction that does not exist.

When is the answer clearly no?

Five situations where accelerating a purchase into this year is the wrong call:

• The cash cost exceeds the benefit. If financing the purchase costs more in interest than the deferral is worth, the deduction is not doing the work you think it is.
• You are already below the business limit and in a low-rate position. A deduction is worth the rate it offsets. At 11.2% it is worth comparatively little, and in a year where income is modest it may be worth more later.
• It is a loss year. A CCA claim that creates or deepens a non-capital loss does nothing for you this year, and CCA is a discretionary deduction — you may claim less than the maximum, or nothing, and preserve the undepreciated capital cost for a year when it offsets income at a higher rate. Claiming CCA into a loss is a common and avoidable error.
• It is a short taxation year. Regulation 1100(3) limits most CCA deductions to the proportion that the number of days in the taxation year bears to 365. A corporation with a stub year gets a correspondingly smaller claim, and the proration is on top of any first-year restriction.
• It is a passenger vehicle. Class 10.1 caps the capital cost you may add, and anything above the ceiling is simply not deductible through CCA at all. A $90,000 car does not produce a $90,000 capital cost. This is the single most common disappointment in year-end asset purchases.

There is also a disposal consequence worth knowing before you buy. When you later sell the asset, proceeds reduce the undepreciated capital cost of the class, and if that drives the balance negative you have recapture brought into income. If you dispose of the last asset in a class for less than its remaining undepreciated capital cost you may have a terminal loss. Neither changes the buy decision often, but both mean a year-end purchase has a tail.

What should I document?

Four things, and they take about ten minutes if you do them at the time and half a day if you reconstruct them in March:

1. The invoice, showing the vendor, the date and the pre-tax capital cost separately from GST/HST.
2. The in-service date, with something contemporaneous behind it — a delivery note, a commissioning sign-off, a photograph, a first production record. This is the evidence for the available-for-use test and it is the item almost always missing.
3. The class determination, with a one-line note on why. “Class 8, general shop equipment, not computer hardware” is enough, and it is what lets someone else reproduce your conclusion in two years.
4. The capital asset register entry, so the asset exists in your books rather than only in the bank statement. This is item eight of our year-end bookkeeping cleanup checklist.

If a year-end purchase is one of several timing decisions you are weighing, the other common one is accruing a bonus to an owner-manager — see our note on the bonus-accrual timing rule. The broader filing context sits in our guide to the T2 corporate tax return for 2026, and the rate change behind the 11.2% figure is covered in our note on Ontario’s 2.2% small business tax rate.

Frequently asked questions

If I buy on December 30, can I claim CCA for this year?

Only if the asset is available for use by your year-end. Subsection 13(26) of the Income Tax Act denies any addition to the undepreciated capital cost before that point, and the invoice date is not the test. For equipment, the usual operative test is delivery plus the capability of being used to produce a commercially saleable product or perform a commercially saleable service.

What is the half-year rule in plain terms?

In the first year you generally get half the normal claim on your net additions to a class. Mechanically, Regulation 1100(2) subtracts half of the amount by which additions exceed dispositions for the class. Property qualifying for an enhanced first-year allowance is excluded from that restriction.

Is a work truck treated the same as a machine?

Not necessarily. Passenger vehicles fall into Class 10.1 and are subject to a capped capital cost — any excess over the ceiling is not deductible through CCA at all. Whether a given truck is a passenger vehicle for this purpose depends on its design and use, so it needs to be determined on the facts rather than assumed.

Does buying equipment reduce my tax by the full purchase price?

No. A capital purchase gives you a deduction, not a credit, and the deduction is spread over years under the CCA rules. At the 11.2% combined Ontario small-business rate, $60,000 of eventual deductions is worth about $6,720 of tax relief in total — roughly eleven cents on the dollar, and spread over time rather than received at once.

What happens if I sell it later?

Proceeds reduce the undepreciated capital cost of the class. If the class balance goes negative, the shortfall is brought back into income as recapture. If you dispose of the last asset in a class for less than the remaining undepreciated capital cost, you may have a terminal loss. Both are reasons to keep the asset register accurate.
