If you use a vehicle for business in Canada, capital cost allowance (CCA) is how you deduct its cost over time on your tax return. Rather than writing off the entire purchase price in one year, the CRA requires you to depreciate the vehicle using the declining-balance method across a specific CCA class. Understanding the rules for capital cost allowance vehicle Canada claims can save you thousands of dollars and keep you audit-ready.
How Capital Cost Allowance Works for Vehicles
CCA uses the declining-balance method. Each year, you apply your class’s CCA rate to the remaining undepreciated capital cost (UCC) of the vehicle. Because the deduction is a percentage of a shrinking balance, the dollar amount you claim decreases every year but never fully reaches zero.
The CRA assigns every business vehicle to one of three classes: Class 10, Class 10.1, or Class 54. Your class determines the CCA rate, whether a cost ceiling applies, and how the half-year rule works. After calculating the raw CCA amount, you multiply it by your business-use percentage to arrive at the actual deduction on your return.
Tripbook makes it easy to calculate that business-use percentage by automatically logging every trip and separating personal from business kilometres throughout the year.
Class 10 vs. Class 10.1 vs. Class 54
The table below summarizes the key differences between the three vehicle CCA classes for 2026:
Class 10 covers motor vehicles such as pickup trucks, vans, and passenger vehicles that cost $39,000 or less (before tax). The CCA rate is 30% on a declining balance with no cost ceiling. Multiple Class 10 vehicles are pooled into a single class, so additions and dispositions affect one shared UCC balance.
Class 10.1 applies to passenger vehicles costing more than $39,000 before tax. The CCA rate is still 30%, but the depreciable amount is capped at $39,000 regardless of what you actually paid. Each Class 10.1 vehicle is placed in its own separate class — you cannot pool them. On disposal, there is no terminal loss and no recapture, which simplifies the tax treatment but eliminates any extra deduction if the car depreciates faster than the CCA schedule.
Class 54 is reserved for zero-emission vehicles (ZEVs) — battery-electric, hydrogen fuel-cell, and qualifying plug-in hybrid vehicles. The base CCA rate is 30%, but an enhanced first-year deduction applies. For vehicles that become available for use in 2026 or 2027, the enhanced rate effectively gives you a 55% write-off in year one. The cost ceiling is $61,000 before tax, and the half-year rule does not apply to this class.
The Half-Year Rule and Accelerated Investment Incentive
In the year you acquire a Class 10 or Class 10.1 vehicle, the half-year rule limits your CCA claim to half the normal rate. It does not matter whether you bought the vehicle in January or December — you can only deduct 15% (half of 30%) of the eligible capital cost in year one.
However, the Accelerated Investment Incentive (AII) — reintroduced under Bill C-15 as the Reaccelerated Investment Incentive — suspends the half-year rule for eligible property acquired after 2024 and available for use before 2030. If your vehicle qualifies as AII property, you apply the full 30% CCA rate in the first year instead of the reduced 15%.
For Class 54 ZEVs, the half-year rule never applies. Instead, you receive the enhanced first-year allowance directly. For 2026 acquisitions, that means a first-year deduction of roughly 55% of the eligible capital cost — a significant acceleration compared to Class 10 or 10.1.
Whether you use the half-year rule or the AII, your CCA deduction is always multiplied by your business-use percentage. Use Tripbook to maintain a CRA-compliant mileage log that substantiates that ratio.
Five-Year CCA Depreciation Example
Below is a side-by-side depreciation schedule showing how UCC and annual CCA deductions evolve over five years for a $50,000 passenger vehicle (Class 10.1, capped at $39,000) versus a $65,000 electric vehicle (Class 54, capped at $61,000). The Class 10.1 example uses the standard half-year rule; the Class 54 example uses the 2026 enhanced first-year rate.
Class 10.1 — $39,000 depreciable cost (30% rate, half-year rule):
| Year | Opening UCC | CCA | Closing UCC |
|---|---|---|---|
| 1 | $39,000 | $5,850 | $33,150 |
| 2 | $33,150 | $9,945 | $23,205 |
| 3 | $23,205 | $6,962 | $16,243 |
| 4 | $16,243 | $4,873 | $11,370 |
| 5 | $11,370 | $3,411 | $7,959 |
Total CCA claimed over five years: $31,041 of the $39,000 cap.
Class 54 — $61,000 depreciable cost (55% enhanced year 1, then 30%):
| Year | Opening UCC | CCA | Closing UCC |
|---|---|---|---|
| 1 | $61,000 | $33,550 | $27,450 |
| 2 | $27,450 | $8,235 | $19,215 |
| 3 | $19,215 | $5,764 | $13,451 |
| 4 | $13,451 | $4,035 | $9,415 |
| 5 | $9,415 | $2,825 | $6,591 |
Total CCA claimed over five years: $54,409 of the $61,000 cap.
The Class 54 vehicle recovers nearly 89% of its depreciable cost within five years, compared to roughly 80% for Class 10.1. The massive year-one deduction is the primary driver of this advantage.
Terminal Loss, Recapture, and Disposal Rules
When you sell or trade in a business vehicle, the tax consequences depend on the class:
Class 10: Your vehicle is part of a pooled class. When you dispose of it, you subtract the lower of the original cost or the sale proceeds from the UCC pool. If the pool balance goes negative, the negative amount is recaptured CCA and added to your business income. If the pool reaches zero with no remaining assets, any positive UCC balance is a terminal loss you can deduct.
Class 10.1: Each vehicle sits in its own class, and special rules apply. In the year you sell a Class 10.1 vehicle, you may claim half the normal CCA on the opening UCC balance. After that, the class is closed with no terminal loss and no recapture. This simplifies your tax filing but means you cannot recover the remaining UCC if the vehicle depreciated faster than the CCA rate.
Class 54: Disposal follows standard pooling rules similar to Class 10. Terminal losses and recapture can both apply depending on the UCC balance and proceeds of disposition.
Tracking CCA Records With Tripbook
The CRA expects you to maintain detailed records for every vehicle you claim CCA on, including the purchase price, date of acquisition, annual UCC balances, CCA amounts claimed, and disposal details. For the business-use percentage, you need a contemporaneous mileage log that separates business and personal driving.
Download Tripbook to automate your mileage tracking and generate CRA-ready reports. Your trip data feeds directly into the business-use percentage that scales every CCA deduction on your return.
