Construction Vehicle Expenses: What Contractors Can Actually Deduct
How vehicle costs are deducted by Ontario construction companies, passenger vehicle versus work vehicle, the 2026 CCA ceilings and lease and interest caps, business-use percentage and logbooks, per-kilometre allowances and standby charges. Written by a licensed Canadian CPA who works with contractors.
A construction company deducts vehicle costs at its business-use percentage, but how much it may claim depends first on whether the vehicle is a passenger vehicle or a work vehicle. Passenger vehicles are capped: $39,000 of capital cost, $1,100 a month of lease payments and $350 a month of loan interest for 2026. A pickup used primarily to carry goods and equipment can fall outside those caps entirely. Every cap is applied before your business-use percentage, not after, and every claim rests on a logbook.
Where the Deduction Is Won or Lost
Vehicles are one of the largest costs a construction business carries, and one of the most commonly misclaimed. A contractor running three trucks between sites, suppliers and the yard has a genuine and substantial deduction. But the rules that govern it are unforgiving in the detail, and the exposure sits in two places.
The first is classification. The capital cost allowance you may claim on a passenger vehicle is capped, as are lease payments and loan interest. A pickup used primarily to transport goods or equipment in the course of business may sit outside the passenger vehicle definition entirely and escape all three caps. The second is records. A business-use percentage without a logbook behind it is an assertion, and the CRA treats it as one. Get both right and the deduction is materially larger. Get either wrong and it is reduced or denied years later with interest.

The 2026 CRA Vehicle Deduction Limits
The Department of Finance announced the 2026 limits on January 14, 2026, effective for the year beginning January 1, 2026. Only two figures moved.
| Limit | 2026 | 2025 | Applies To |
|---|---|---|---|
| Class 10.1 CCA ceiling | $39,000 | $38,000 | Passenger vehicles acquired on or after January 1, 2026, before tax |
| Class 54 CCA ceiling | $61,000 | $61,000 | Zero-emission passenger vehicles, new and used, before tax |
| Deductible lease cost | $1,100 | $1,100 | Per month before tax, new leases from January 1, 2026 |
| Deductible loan interest | $350 | $350 | Per month, new loans from January 1, 2026 |
| Allowance, first 5,000 km | 73 cents | 72 cents | Per kilometre, tax-exempt allowance limit, provinces |
| Allowance, additional km | 67 cents | 66 cents | Per kilometre, tax-exempt allowance limit, provinces |
| Operating benefit rate | 34 cents | 34 cents | Per kilometre, personal portion of employer-paid expenses |
Every cap is applied before your business-use percentage, not after. A $1,400 monthly lease on a truck used 70% for business gives a deduction based on $1,100, not $1,400. These limits are reviewed annually and change. Please confirm the current figures before relying on them for a purchase or a filing.
Passenger Vehicle or Work Vehicle: The Classification That Decides Everything
This is the single most important question on the page, because it determines whether the caps apply at all. A passenger vehicle is designed primarily to carry people and their luggage. A pickup used primarily to transport goods, tools or equipment in the course of business can fall outside that definition, and with it, outside the ceiling, the lease cap and the interest cap.
| Factor | Passenger Vehicle | Work Vehicle |
|---|---|---|
| CCA ceiling | Capped at the Class 10.1 ceiling | No ceiling, Class 10 pool |
| Lease cap | Applies | Does not apply |
| Interest cap | Applies | Does not apply |
| Class treatment | Class 10.1, each vehicle separate | Class 10, pooled together |
| Typical example | Sedan, SUV, crew-cab used mainly to move people | Pickup used primarily to carry goods, tools and equipment |
| What decides it | Design, seating capacity and actual use | Design, seating capacity and actual use |
This is a question of fact, decided vehicle by vehicle. Calling a truck a work vehicle does not make it one, and the CRA will look at how it is actually used. A fleet is rarely uniform, so each vehicle should be assessed at acquisition rather than years later under review.
Worked Example: A $52,000 Truck
The same truck, the same 75% business use, treated two ways. Figures use the 2026 limits and are illustrative.
| Step | As a Passenger Vehicle | As a Work Vehicle |
|---|---|---|
| Purchase price, before tax | $52,000 | $52,000 |
| Capital cost recognised | $39,000 (capped) | $52,000 (no cap) |
| Amount excluded from CCA | $13,000 | $0 |
| Class | Class 10.1, separate class | Class 10, pooled |
| Loan interest, actual $520/month | $350/month deductible | $520/month deductible |
| Interest lost to the cap, per year | $2,040 | $0 |
| Business-use percentage applied | 75%, after the caps | 75%, no caps |
| Recapture on later sale | No recapture on Class 10.1 | Recapture possible from the pool |
The classification is worth $13,000 of capital cost and $2,040 of interest a year on this one truck. Across a fleet the difference compounds. These figures are illustrative and depend on your facts. Please have your vehicles assessed properly rather than assuming.
Business Use, and the Record That Proves It
Your business-use percentage is business kilometres over total kilometres, and both numbers must be recorded. Driving between sites, to suppliers and to the yard is business use. Driving from home to a regular place of work is generally personal commuting, even in a work truck. Everything after hours and at weekends is personal.
- Record every business trip. Date, destination, purpose and kilometres driven. An app is fine, provided it is complete and kept as you go.
- Take odometer readings at year end. The start and end readings give you total kilometres, which is half the calculation.
- Calculate, do not estimate. Business kilometres divided by total kilometres gives the percentage every expense is then multiplied by.
- Keep it. The logbook is the first thing the CRA asks for, and reconstructing one after the fact is far harder than maintaining it.
Claiming 100% business use on a vehicle that goes home each night is the fastest way to attract a review. It is rarely plausible, and without a logbook it cannot be defended. A realistic percentage properly supported is worth more than an optimistic one that gets denied.
Allowances, Standby Charges and the Worker Side
Where a worker uses their own truck, a per-kilometre allowance at the prescribed rate is tax-free to them and deductible to you, but only if it is based solely on business kilometres driven, the rate is reasonable, and no other allowance is paid for the same vehicle. A flat monthly car allowance fails those conditions and is generally taxable.
Where the corporation owns the truck and it is available to the driver for personal use, a standby charge arises, calculated on the cost or lease of the vehicle and the availability, along with a separate operating cost benefit. Both are taxable to the driver and both are frequently missed on owner-driven trucks. Please see our construction payroll services.
HST, Job Costing and the Rest of the Fleet
Input tax credits on a passenger vehicle are restricted by reference to the capital cost ceiling and your business-use percentage, so the HST treatment does not simply follow the income tax claim. Trailers, excavators, skid steers and similar equipment are not passenger vehicles at all: they fall into their own capital cost allowance classes with no caps. Fines are never deductible, and capital improvements are added to the vehicle's cost rather than expensed in the year.
Finally, fuel and running costs sitting in a single overhead account distort your job costing. Drive-heavy jobs look more profitable than they are until the vehicle cost is allocated to them. Please see our construction bookkeeping.
Where contractors get vehicle expenses wrong: claiming 100% business use on a truck that obviously goes home each night, keeping no logbook at all, missing the passenger vehicle caps entirely, expensing a vehicle that should be capitalised, ignoring the standby charge on a corporate truck, and paying a flat monthly car allowance without reporting the benefit.
Case Study: General Contractor, Ontario
A contractor was treating four pickups as passenger vehicles and capping the capital cost allowance on all of them, while claiming 100% business use on a truck that went home every night with no logbook behind it. We assessed how each vehicle was actually used, established that three were used primarily to transport tools, materials and equipment and reclassified them out of the passenger vehicle rules, which lifted the ceiling on those trucks. We then rebuilt the driving record from job schedules and site addresses, established a defensible business-use percentage on the fourth, and allocated fuel and running costs to the jobs that caused them. The result was a materially larger deduction on the qualifying trucks and a claim that would survive a review rather than collapse under one. The figures here are illustrative of the work we do, not a specific client file.
