If you run a business and lease a vehicle, the CRA's 85% lease limit rule is one of the most important tax provisions to understand.
Understanding the CRA Lease Cap Rule
The CRA lease cap rule limits the amount you can deduct for a leased vehicle when the monthly lease payment exceeds a certain threshold. This is governed by Section 248(1) of the Income Tax Act and clarified in CRA Interpretation Note IT-521.
The rule exists to prevent business owners from using expensive luxury vehicle leases to generate large tax deductions, while ensuring that the taxable benefit rules remain consistent between leased and owned vehicles.
The 85% Limit — How It Works
Under the 85% rule, if you lease a vehicle and use it partly for personal purposes, you can deduct up to 85% of the total lease payments (plus operating costs) as business expenses — but only if the lease contract would otherwise allow a deduction for 100% of the payment.
In practical terms:
- If you use the vehicle 100% for business: You can potentially deduct the full lease payment, subject to the lease cap amount
- If you use the vehicle 85% for business: You deduct 85% of the lease payments
- If the vehicle is used 100% personally: No deduction at all
The business-use percentage must be supported by a detailed logbook maintained throughout the year.
The Lease Cap Amount — When It Applies
The lease cap rule applies when the monthly lease payment would otherwise result in a deduction that exceeds what would be available under the Capital Cost Allowance (CCA) system for an owned vehicle. The CRA calculates a monthly lease cap based on:
- The original manufacturer's suggested retail price (MSRP) of the vehicle
- The financing rate implicit in the lease
- The prescribed rate set by the CRA annually
For 2026, the CRA prescribes a specific cap amount. If your monthly lease payment exceeds this cap, the excess portion cannot be deducted even if you use the vehicle 100% for business.
Capital Cost Allowance (CCA) for Owned Vehicles
If you purchase a vehicle for business use instead of leasing it, you claim Capital Cost Allowance (CCA). For most passenger vehicles, this falls under Class 10.1, which uses a 30% declining balance depreciation method.
CRA Vehicle Deduction — Leased vs. Owned (2026)
| Method | Deduction | Business Use % | CRA Form |
|---|---|---|---|
| Leased vehicle | Up to 85% of lease + expenses | Business use % | T2200 required |
| Owned vehicle (Class 10.1) | 30% declining balance CCA | Business use % | T2125 / Form 4569 |
| Operating costs (leased) | Gas, insurance, maintenance | Business use % | T2200 required |
| Operating costs (owned) | Actual costs | Business use % | T2125 |
The T2200 Form — Employment Conditions Certificate
For employees claiming vehicle expenses, the CRA requires a T2200 (Conditions of Employment) form to be completed by the employer. This form confirms that the employee was required to:
- Work away from the employer's place of business, OR
- Pay for expenses without reimbursement under a taxable benefit arrangement
For self-employed individuals, the T2200 is not required — but you must maintain records demonstrating that the vehicle was used for business purposes and the percentage of business use.
Employer-Provided Vehicles — Standby Benefit
When an employer provides a vehicle to an employee, a taxable standby benefit is calculated. The employee reports this benefit on their T4. The standby benefit is typically calculated using one of two methods:
- Standby benefit percentage: A percentage of the original cost of the vehicle, multiplied by days of personal use
- Kilometre-based method: A fixed rate per personal kilometre driven
Key point: If an employee uses a company vehicle 100% for business and never for personal purposes, the standby benefit is $0.
GST/HST and the Lease Deduction
The GST/HST paid on lease payments is treated as follows:
- For personal-use lease vehicles: GST/HST is not deductible
- For business-use vehicles: GST/HST on the business portion may be recoverable through Input Tax Credits (ITCs)
- Businesses registered for GST/HST should claim ITCs on the business-use portion of all vehicle expenses, including lease payments
Record-Keeping Requirements for Vehicle Deductions
Both the CRA and provincial tax authorities require thorough record-keeping for vehicle deductions:
- Logbook: A contemporaneous log of business vs. personal trips, including dates, kilometres, and purpose
- Receipts: All vehicle-related expense receipts
- Lease agreement: Copy of the vehicle lease contract
- T2200: For employees, the completed employer form
- Supporting documents: Registration, insurance, maintenance records
Records should be kept for a minimum of 6 years in case of CRA audit.
Frequently Asked Questions
What is the CRA lease cap for 2026?
The CRA lease cap amount is recalculated annually based on prescribed rates and vehicle MSRP. For 2026, check the CRA Interpretation Note IT-521 or consult a tax professional for the current monthly cap amount. The cap applies to the portion of the lease payment attributable to the vehicle's value above the prescribed limit.
Can I claim both Section 179 (US) and the Canadian lease deduction?
These are different country's tax systems. Section 179 is a US tax provision that does not apply in Canada. Canadian businesses use Capital Cost Allowance (CCA) for owned vehicles and are subject to the Section 248 lease cap rules for leased vehicles. Consult a Canadian tax professional for your specific situation.
Can sole proprietors claim vehicle lease deductions?
Yes — sole proprietors can claim vehicle lease deductions subject to the 85% limit and business-use percentage. Sole proprietors use Form T2125 (Business Activities) to report business income and expenses, including vehicle costs. No T2200 is required for sole proprietors.
What if my business use of a leased vehicle drops below 50%?
If your business use drops below 50%, you may lose eligibility for certain deductions. For employees, vehicle deductions are only available if more than 50% of employment duties involve the use of a motor vehicle. For business owners, a logbook demonstrating the business-use percentage is essential for any audit.
Is the lease cap rule the same for GST purposes?
For GST/HST Input Tax Credit purposes, the lease cap applies to the total deductible lease amount. Only the GST/HST attributable to the deductible portion of the lease can be claimed as an ITC. This prevents business owners from claiming full GST credits on a vehicle that is partially personal use.
Conclusion
The CRA's 85% lease limit rule under Section 248 and IT-521 is a critical constraint for any Canadian business owner or employee claiming vehicle lease deductions. Understanding how this cap interacts with your monthly lease payment, your business-use percentage, and the GST/HST treatment of the lease can mean the difference between a valid, beneficial deduction and an audit-triggering overclaim.
