Every year, the Department of Finance Canada updates the automobile deduction limits that cap how much businesses and individuals can claim for vehicle expenses. On January 14, 2026, Finance Canada confirmed the automobile deduction limits 2026 Canada figures — and while some ceilings went up, several stayed flat. Here is every limit you need, how each one works in practice, and what changed from 2025.
Complete 2025 vs 2026 Limits Comparison
Before diving into details, here is the full picture. Every automobile deduction limit for 2026, compared against 2025:
| Category | 2025 | 2026 | Change |
|---|---|---|---|
| CCA ceiling — Class 10.1 (passenger vehicles) | $38,000 | $39,000 | +$1,000 |
| CCA ceiling — Class 54 (zero-emission vehicles) | $61,000 | $61,000 | No change |
| Monthly lease deduction cap | $1,100 | $1,100 | No change |
| Monthly interest deduction cap | $350 | $350 | No change |
| Per-km allowance — first 5,000 km (provinces) | $0.72 | $0.73 | +$0.01 |
| Per-km allowance — additional km (provinces) | $0.66 | $0.67 | +$0.01 |
| Per-km allowance — first 5,000 km (territories) | $0.76 | $0.77 | +$0.01 |
| Per-km allowance — additional km (territories) | $0.70 | $0.71 | +$0.01 |
| Operating cost benefit rate (general) | $0.34 | $0.34 | No change |
| Operating cost benefit rate (auto sales/leasing) | $0.31 | $0.31 | No change |
All CCA and lease limits are before applicable GST/HST. The per-km allowance rates apply to tax-exempt allowances paid by employers to employees using personal vehicles for business.
CCA Cost Ceilings: Class 10.1 and Class 54
When you purchase a vehicle for business, the Income Tax Act limits the capital cost you can use for CCA calculations. For 2026, there are two key thresholds.
Class 10.1 — Passenger vehicles above $39,000. The CCA ceiling increased from $38,000 (2025) to $39,000 before tax for vehicles acquired on or after January 1, 2026. If your vehicle costs more than this amount, only $39,000 enters the CCA pool. The CCA rate remains 30%.
Example: You buy a pickup truck for $58,000. Because the cost exceeds $39,000, the vehicle goes into Class 10.1. Your CCA base is $39,000. First-year CCA with the half-year rule: $39,000 × 30% × 50% = $5,850. You lose the ability to depreciate $19,000 of the purchase price.
Class 54 — Zero-emission vehicles. The CCA ceiling stays at $61,000 before tax for 2026. The CCA rate is 55%, giving ZEVs a significant first-year advantage.
Example: You buy an electric vehicle for $65,000. The CCA base is capped at $61,000. First-year CCA: $61,000 × 55% × 50% = $16,775. Compare that to $5,850 for a gas vehicle at the same price — a difference of $10,925 in year-one write-offs. For more on how Class 54 works, see capital cost allowance vehicle Canada.
Class 10 — Vehicles under $39,000. No CCA ceiling applies. The full purchase price enters the undepreciated capital cost pool at a 30% CCA rate.
Lease and Interest Deduction Caps
Two limits govern financed vehicles: the lease cap and the interest cap. Both are unchanged for 2026.
Lease deduction cap: $1,100 per month (before GST/HST). This limit applies to the base lease payment only — not to operating costs like fuel, insurance, or maintenance. If your lease payment is $950/month, the full amount qualifies. If your lease is $1,400/month, only $1,100 is potentially deductible before applying your business-use percentage.
Example: A self-employed consultant leases a vehicle at $1,300/month with 75% business use. Deductible lease cost = $1,100 (capped) × 75% = $825/month, or $9,900/year on line 9281 of the T2125. The $200/month excess is permanently non-deductible. For a deeper comparison of leasing versus buying, see lease vs buy car business Canada.
Interest deduction cap: $350 per month ($11.67/day). This applies to the interest portion of auto loan payments only — principal repayments are never deductible.
Example: You finance a $45,000 vehicle at 6.5% over 5 years. Monthly interest in year one averages roughly $220. Since $220 is under the $350 cap, you can deduct the full amount (times business-use %). If rates were higher and your monthly interest hit $420, only $350 would qualify.
Per-Kilometre Allowance Rates for 2026
The tax-exempt mileage allowance rates — the amounts employers can reimburse employees without triggering a taxable benefit — increased by one cent across the board for 2026.
Provinces:
- First 5,000 km: $0.73/km (up from $0.72)
- Each additional km: $0.67/km (up from $0.66)
Territories (Yukon, NWT, Nunavut):
- First 5,000 km: $0.77/km (up from $0.76)
- Each additional km: $0.71/km (up from $0.70)
Example: An employee in Ontario drives 18,000 business kilometres in 2026. Their maximum tax-free allowance: (5,000 × $0.73) + (13,000 × $0.67) = $3,650 + $8,710 = $12,360. If the employer pays more than this, the excess becomes taxable income on the T4. If the employer pays less, the employee can claim the shortfall as an expense on their tax return. For the full breakdown of how CRA mileage rates work, see CRA mileage rate 2026.
Tripbook automatically calculates your annual business kilometres and generates a CRA-compliant mileage log that supports these allowance claims.
Operating Cost Benefit and Standby Charge
Employees who drive an employer-provided vehicle for personal use face two taxable benefit calculations.
Operating cost benefit: $0.34 per personal kilometre for 2026 (unchanged from 2025). This rate applies to the general employee population. For employees principally engaged in selling or leasing automobiles, the rate is $0.31/km.
Example: An employee drives a company car 5,000 personal kilometres in 2026. The operating cost benefit added to their T4: 5,000 × $0.34 = $1,700 in additional taxable income.
Standby charge: 2% per month of the vehicle’s original cost (or two-thirds of the monthly lease cost for leased vehicles). For a $48,000 company vehicle available all year: $48,000 × 2% × 12 = $11,520 added to the T4.
The reduced standby charge is available when the vehicle is driven more than 50% for business and personal use stays under 20,004 km/year. The reduction uses the formula: (personal km ÷ 20,004) × full standby charge. This makes accurate mileage tracking essential — the difference between a full and reduced standby charge can easily exceed $5,000 per year.

How to Apply These Limits on Your Tax Return
The automobile deduction limits 2026 Canada do not work in isolation. Here is how they combine for a typical self-employed taxpayer.
Scenario: You are self-employed, bought a $52,000 vehicle in January 2026, and drove 24,000 km total — 18,000 for business (75% business use).
- CCA: Vehicle exceeds $39,000 → Class 10.1. Base = $39,000. Year 1 CCA = $39,000 × 30% × 50% = $5,850 × 75% = $4,388 deductible
- Interest: Loan interest averages $290/month (under $350 cap). Annual = $3,480 × 75% = $2,610 deductible
- Operating costs: Fuel $5,200 + insurance $2,400 + maintenance $1,600 = $9,200 × 75% = $6,900 deductible
- Total vehicle deduction: $4,388 + $2,610 + $6,900 = $13,898 flowing to T2125
Every calculation depends on the business-use percentage, and that percentage depends on an accurate mileage log. Without one, the CRA can deny the entire deduction — not just reduce it.
Tripbook tracks every trip with GPS precision and calculates your business-use percentage automatically. No spreadsheets, no guesswork — just a CRA-ready log when you need it. Download Tripbook and make sure every kilometre counts toward your 2026 deductions.
