An excavator, a pickup truck and a set of shop tools all count as capital equipment, but the Income Tax Regulations don't treat them as one category. Which class a specific purchase falls into decides how quickly its cost can actually be written down.
Key takeaways
Deciding to buy a piece of equipment is a cash and utilization question, covered separately. What happens to that purchase on the tax return afterward is a different question, and it starts with a classification the Income Tax Regulations make for the taxpayer, not a choice the taxpayer gets to make itself.
Equipment that doesn't fit a more specific class defaults to Class 8, at a 20% declining-balance rate. Construction equipment usually doesn't stay in the default category, because the regulations carve out more specific classes that apply first. Class 10 names construction directly: “contractor's movable equipment, including portable camp buildings, acquired for use in a construction business or for lease to another taxpayer for use in that other taxpayer's construction business” — a category built for exactly this industry, at a faster 30% rate. A narrower category again, Class 38, picks up power-operated excavating and earthmoving equipment specifically: “property not included in Class 22 but that would otherwise be included in that class if that class were read without reference to” Class 22's own acquisition-date restrictions — in substance, the same “power-operated movable equipment designed for the purpose of excavating, moving, placing or compacting earth, rock, concrete or asphalt” Class 22 was built for, now written down at 30% as well. Shop machinery used specifically for manufacturing or processing — a pre-fab or modular component shop, for instance — can fall under Class 43 instead, also at 30%, rather than either construction-specific class.
The rates themselves come from a separate section of the regulations, not Schedule II's class descriptions: Class 8 at 20%, Class 10 at 30%, Class 38 at 30% and Class 43 at 30%. Getting the class wrong isn't just a paperwork error — a bulldozer mistakenly filed under the generic 20% default, instead of the 30% class it actually belongs in, is written off measurably slower than it should be, understating the deduction in every early year the equipment is owned.
Whichever class applies, the deduction in the year of purchase is restricted. The regulation's own formula for the allowable deduction subtracts half of net additions to the class before applying the class rate — in practice, only half the equipment's cost is available to generate a deduction in the first year, with the remainder available at the full rate starting the following year. A company modelling the tax effect of a purchase in its acquisition year, using the full rate on the full cost, is overstating that year's deduction.
A worked example
An excavator purchased for $185,000.00 falls into Class 38, at 30%. In the year of purchase, the half-year rule applies to half the cost: $185,000.00 × 0.5 = $92,500.00 is the base the 30% rate is applied against for that year. Year one's CCA deduction is $92,500.00 × 0.30 = $27,750.00, leaving an undepreciated capital cost of $157,250.00 ($185,000.00 − $27,750.00) going into year two.
Year two applies the full 30% rate to the remaining balance, with no further half-year restriction on this addition: $157,250.00 × 0.30 = $47,175.00, leaving $110,075.00 ($157,250.00 − $47,175.00) carried forward. The deduction keeps declining on the same shrinking balance every year the equipment stays in service, never reaching zero on its own — which is why what happens at disposal, not just during ownership, is part of the same calculation.
CCA is also tracked by class as a whole, not machine by machine. A second excavator bought the following year, also Class 38, is added to the same declining balance as the first — there's one undepreciated capital cost figure per class, not a separate schedule for every individual asset. That pooling is what makes recapture and terminal loss class-level questions too: selling one machine out of a class that still holds other equipment behaves differently from selling the last piece of equipment the class contains, because the balance the sale proceeds are measured against is the whole class's, not that one machine's original cost.
Disposal closes the loop in one of two directions, and which one applies depends on what's happened to the rest of the class. Sell the equipment for more than its remaining undepreciated capital cost, and the excess is added back to income as recapture — the Act's own wording: where the amounts credited to the class “exceed the total of the amounts” otherwise determined, “the excess shall be included in computing the taxpayer's income of the year.” The CCA claimed in earlier years, in other words, gets clawed back to the extent the equipment turned out to be worth more than its written-down value.
The reverse situation is a terminal loss: if the taxpayer no longer owns any property in that class at year end and a balance remains after the disposal, that remaining balance is deductible in full. The Act permits the deduction “notwithstanding” the general capital-expenditure restriction, precisely because the class has been emptied and there's nothing left to write down gradually. Whether a piece of equipment is worth owning in the first place already accounts for financing and utilization — the tax treatment on the way out is the last piece of that same lifecycle calculation.
Typically Class 38, at a 30% declining-balance rate, which covers power-operated equipment for excavating, moving, placing or compacting earth, rock, concrete or asphalt. Other construction equipment, including portable camp buildings, generally falls under Class 10, also at 30%; equipment that doesn't fit either named category defaults to Class 8 at 20%.
No. The half-year rule restricts the deduction in the year of acquisition to the class rate applied against only half the net addition to the class. The remaining half becomes available at the full rate starting the following year.
If the sale proceeds exceed the equipment's remaining undepreciated capital cost, the excess is added back to income as recapture. If the taxpayer no longer owns any property in that class and a balance remains after the sale, that balance is instead deductible in full as a terminal loss. Which one applies depends on the sale price and on whether other property remains in the same class.
