Choosing whether to buy vs lease vs finance a car for business in Canada is one of the most consequential tax decisions a business owner makes. Each path triggers different CRA rules for deductions, capital cost allowance, interest caps, and GST/HST recovery. This guide compares all three options side by side — with a worked $55,000 vehicle example — so you can pick the structure that saves the most tax over five years.
How CRA Treats Each Option
The Income Tax Act draws a hard line between ownership and leasing. When you buy or finance, the vehicle is a capital asset and you recover its cost through CCA. When you lease, the payments are an operating expense capped by CRA limits. Here is the core distinction:
Buy (cash): You own the vehicle outright. Claim CCA each year on the capital cost. No interest deduction applies because there is no loan. GST/HST is paid in full at purchase and recovered as an Input Tax Credit on your next return.
Finance (loan): You also own the vehicle and claim CCA identically to a cash purchase. In addition, loan interest is deductible up to $350 per month. GST/HST is paid at purchase and the ITC is claimed upfront.
Lease: You never own the vehicle. Monthly lease payments are deductible up to $1,100 per month (before tax). No CCA is claimed. GST/HST is charged on each lease payment and recovered as an ITC each reporting period.
All three methods require you to apply your business-use percentage to every deduction. That percentage must be supported by a CRA-compliant mileage log — Tripbook automates this with GPS tracking.
2026 CRA Deduction Limits at a Glance
Before running the numbers, here are the key limits for vehicles acquired on or after January 1, 2026:
| Rule | 2026 Limit |
|---|---|
| Class 10.1 CCA ceiling (non-EV passenger vehicle) | $39,000 + tax |
| Class 10 CCA rate | 30% declining balance |
| Class 10.1 CCA rate | 30% declining balance (separate class per vehicle) |
| Class 54 ZEV ceiling | $61,000 + tax |
| Class 54 enhanced first-year rate (2026–2027) | ~25% (30% x 5/6 multiplier) |
| Maximum deductible lease payment | $1,100/month before tax |
| Maximum deductible loan interest | $350/month ($11.67/day) |
| Half-year rule (Year 1 CCA) | 50% of normal CCA in acquisition year |
Class 10 covers passenger vehicles costing $39,000 or less. Class 10.1 applies when the cost exceeds $39,000 — the capital cost is capped at $39,000 for CCA purposes regardless of the actual price. Class 54 applies to zero-emission vehicles with a higher $61,000 ceiling.
$55,000 Vehicle: 5-Year Comparison
Let us compare a $55,000 vehicle (before tax) under all three methods over five years, assuming 80% business use. For the financed option, assume a 6.5% loan rate over 60 months.
Buy (Cash) — Class 10.1
Because the vehicle costs more than $39,000, it enters Class 10.1 with a capped capital cost of $39,000.
| Year | UCC Start | CCA (30%) | Business Deduction (80%) |
|---|---|---|---|
| 1 | $39,000 | $5,850 (half-year) | $4,680 |
| 2 | $33,150 | $9,945 | $7,956 |
| 3 | $23,205 | $6,962 | $5,569 |
| 4 | $16,244 | $4,873 | $3,898 |
| 5 | $11,370 | $3,411 | $2,729 |
| Total | $31,041 | $24,832 |
No interest deduction. GST/HST ITC claimed in Year 1 on the full purchase price.
Finance (Loan) — Class 10.1 + Interest
Same CCA as cash, plus deductible interest capped at $350/month:
| Year | CCA Deduction (80%) | Interest Deduction (80%) | Total (80%) |
|---|---|---|---|
| 1 | $4,680 | $3,360 | $8,040 |
| 2 | $7,956 | $3,360 | $11,316 |
| 3 | $5,569 | $3,360 | $8,929 |
| 4 | $3,898 | $3,360 | $7,258 |
| 5 | $2,729 | $3,360 | $6,089 |
| Total | $24,832 | $16,800 | $41,632 |
Interest deduction: $350 x 12 = $4,200/year x 80% = $3,360/year. Over five years that adds $16,800 in deductions beyond what cash purchase provides.
Lease — $950/month
For a $55,000 vehicle, a typical 60-month lease runs approximately $950/month (under the $1,100 cap):
| Year | Lease Payments | Business Deduction (80%) |
|---|---|---|
| 1 | $11,400 | $9,120 |
| 2 | $11,400 | $9,120 |
| 3 | $11,400 | $9,120 |
| 4 | $11,400 | $9,120 |
| 5 | $11,400 | $9,120 |
| Total | $57,000 | $45,600 |
The lease produces the highest total deduction — $45,600 versus $41,632 for financing and $24,832 for cash. However, you own nothing at term end and have paid $57,000 in total lease costs for a $55,000 vehicle.
GST/HST Recovery Timing
The timing of GST/HST recovery can affect your cash flow in Year 1:
Buy or finance: You pay GST/HST on the full $55,000 at the dealership. At a combined 13% HST (Ontario), that is $7,150 paid upfront. You claim the business-use portion ($7,150 x 80% = $5,720) as an ITC on your next GST/HST return. This creates a large upfront cash outflow but a significant ITC recovery in the first reporting period.
Lease: GST/HST is paid on each monthly lease payment. At $950/month, the HST portion is $123.50/month. You claim 80% ($98.80) as an ITC each period. The recovery is smaller per period but perfectly matched to cash outflows — better for businesses managing tight cash flow.
For GST/HST-registered businesses with 90% or greater commercial use, the full ITC can be claimed without proration. See our guide on GST/HST input tax credits for vehicles for the complete rules.
Zero-Emission Vehicles Change the Math
If the $55,000 vehicle is a zero-emission vehicle, buying or financing becomes significantly more attractive. The vehicle enters Class 54 with the full $55,000 capital cost (under the $61,000 ceiling), and the enhanced first-year CCA applies.
For vehicles available for use in 2026, the first-year multiplier is 5/6, making the effective first-year rate approximately 25%:
Year 1 ZEV CCA: $55,000 x 25% = $13,750 x 80% = $11,000
Compare that to the lease deduction of $9,120 in Year 1. Over the full five years, the ZEV purchase produces substantially higher total CCA because the full $55,000 enters the pool rather than being capped at $39,000.
When you factor in the federal iZEV rebate (up to $5,000) available on eligible purchases, the ownership path for electric vehicles delivers both higher deductions and a lower net cost. Note that vehicles receiving the iZEV rebate cannot be placed in Class 54 — they are reclassified to Class 10.1 instead, so you need to model both scenarios with your accountant.

Which Option Wins for Your Business?
There is no universal answer. The best choice depends on vehicle cost, business-use percentage, cash position, and whether you want to own the vehicle long term.
| Factor | Cash Purchase | Financed | Lease |
|---|---|---|---|
| CCA deduction | Yes (30% DB) | Yes (30% DB) | No |
| Interest deduction | No | Yes (max $350/mo) | No |
| Lease deduction | No | No | Yes (max $1,100/mo) |
| 5-year deduction ($55K, 80%) | $24,832 | $41,632 | $45,600 |
| GST/HST recovery | Upfront lump sum | Upfront lump sum | Spread monthly |
| Residual value at end | You keep vehicle | You keep vehicle | Return vehicle |
| Best for | High capital, low-cost vehicles | Standard business vehicles | Cash preservation, flexibility |
Choose cash when the vehicle costs under $39,000 (full cost enters CCA pool) and you have the capital available.
Choose financing when you want to preserve cash, build equity in the vehicle, and take advantage of both CCA and interest deductions.
Choose leasing when cash flow flexibility matters most, you prefer to drive a newer vehicle every few years, or the vehicle cost significantly exceeds the Class 10.1 cap.
Whichever path you choose, the business-use percentage is the multiplier that determines how much of every deduction you actually claim. The difference between 70% and 85% business use on a financed vehicle is over $6,200 in lost deductions over five years.
