» Quick Answer
- A car allowance paid by a Canadian employer is tax-free only when it meets three CRA conditions: it is based solely on kilometres driven for business, the per-kilometre rate is reasonable, and no separate reimbursement is paid for the same vehicle use.
- For 2026, the CRA considers 73 cents per kilometre reasonable for the first 5,000 business kilometres in a year and 67 cents per kilometre after that, with an extra 4 cents in Yukon, the Northwest Territories and Nunavut.
- Flat monthly car allowances almost always fail the first condition and are treated as fully taxable employment income – included in Box 14 of the T4, separately identified in Box 40, and subject to income tax, CPP and EI withholding.
- If your allowance is taxable, ask your employer for a signed Form T2200 so you can deduct your actual motor vehicle expenses on your T1 return.
» Why Your Car Allowance Landed on Your T4
It is late February. Your T4 slip arrives, and Box 14 is higher than the salary you thought you earned. The $500-a-month car allowance you treated as a perk has been rolled straight into your employment income, tax was withheld on it, and you are wondering whether payroll made a mistake.
It is probably not a mistake. The Canada Revenue Agency (CRA) draws a sharp line between a car allowance that qualifies as tax-free and one that does not, and small structural differences change the outcome entirely. This article explains where that line sits in 2026, what it means for your paycheque or your payroll, and what to do if the allowance you receive, or pay, ended up on the wrong side of it.

Which section you need depends on your role. Employees receiving an allowance should start with how the CRA decides taxability and how the T4 is reported. Employers and HR contacts should focus on the 2026 rates and the common mistakes. Owner-managers paying themselves through a corporation should read both paths.
The rules covered here apply to allowances and reimbursements paid to employees who use their own vehicle. They do not cover an employer-provided vehicle, which follows separate standby-charge and operating-benefit rules.

» How the CRA Decides If Your Car Allowance Is Taxable
The CRA treats a car allowance as tax-free only when three conditions are met at the same time: the allowance is based solely on kilometres driven for business, the per-kilometre rate is reasonable, and the employee is not separately reimbursed for the same vehicle use. Miss any one, and the entire allowance is treated as taxable employment income under paragraph 6(1)(b) of the Income Tax Act.
The first condition is the one most employers stumble on. An allowance is based solely on kilometres only when the payment moves up and down with actual business driving. A flat $500 a month, or any figure calculated on anything other than a documented kilometre count, generally fails this test even if the number was derived from estimated annual mileage.
The second condition is about the rate. The CRA publishes a reasonable per-kilometre rate each year (covered in the next section). Rates materially above the published figure make the excess, or in some cases the whole allowance, taxable. Rates set unreasonably low can also fail because they no longer reflect the true cost of driving.
The third condition prevents double-dipping. An employer cannot pay a per-kilometre allowance and also reimburse the employee for fuel, insurance or maintenance for the same driving. A fuel card issued on top of a per-kilometre allowance is the classic trigger, and the CRA typically treats both payments as taxable when this happens.
» The 2026 CRA Per-Kilometre Rates: What Counts as Reasonable
For 2026, the CRA considers 73 cents per kilometre reasonable for the first 5,000 business kilometres driven in the calendar year, and 67 cents per kilometre for every kilometre after that. Employees driving in Yukon, the Northwest Territories or Nunavut can add 4 cents per kilometre to both tiers, giving 77 cents and 71 cents respectively.
These figures are set annually by the Department of Finance Canada and published under section 7306 of the Income Tax Regulations. The 2026 rates are one cent per kilometre higher than 2025 in every tier, continuing a slow upward drift tied to vehicle operating costs.
The practical read for a Canadian employer is straightforward: pay a per-kilometre allowance at or below these rates, tie it to a written kilometre log, and keep the allowance separate from any receipt-based reimbursement, and the payment is generally tax-free to the employee and fully deductible for the business. Our 2026 payroll guide for Canadian employers walks through the withholding mechanics that apply when a payment does not qualify.
» Car Allowance vs. Mileage Reimbursement vs. Employer-Provided Vehicle
Three arrangements look similar on paper but are taxed very differently. A per-kilometre allowance at or below the CRA rate is generally tax-free. A reimbursement of actual costs against receipts is also tax-free when it covers business use only. An employer-provided vehicle is taxable through the separate standby-charge and operating-benefit rules.
A per-kilometre allowance is the cleanest option. The employee submits a log, the employer pays the log times the rate, and nothing appears on the T4 if the three conditions above are met. A flat monthly allowance is the most common trap: the payment is fixed regardless of driving, which fails condition one, and the full amount is taxable.
An actual-cost reimbursement works differently. The employee pays for fuel, insurance and repairs, then submits receipts and a business-kilometre record. The employer refunds the business-use share. This is generally tax-free but requires strong document controls, which our note on preventing employee expense fraud addresses.
An employer-provided vehicle is a different animal. Personal use of a car the employer owns or leases triggers a standby charge (a percentage of the vehicle cost) and, when the employer covers operating costs, an operating expense benefit. These amounts land in Box 34 of the T4, not Box 40, and follow their own rules outside this article.
| Arrangement | Tax-Free by Default? | T4 Reporting | Log Required? | Can Employee Claim Actual Expenses on T1? |
|---|---|---|---|---|
| Per-km allowance at CRA rate | Yes (if 3 conditions met) | Not reported on T4 | Yes – kilometre log | No – already tax-free |
| Flat monthly car allowance | No | Box 14 + Box 40 | Not required for allowance; needed for T1 recovery | Yes – with signed Form T2200 |
| Reimbursement of actual costs (receipts) | Yes (business use only) | Not reported on T4 | Yes – log plus receipts | No – already reimbursed |
| Employer-provided vehicle | No – standby & operating benefit | Box 34 (separate rules) | Yes – personal-use km | N/A – not employee-owned |
» What Happens on Your T4: Box 14, Box 40 and Withholdings
When a car allowance is taxable, the employer reports it two ways on the T4 slip. The full amount is included in Box 14 (employment income), and the same amount is separately identified in Box 40 (other taxable allowances and benefits). Income tax, Canada Pension Plan contributions and Employment Insurance premiums are withheld as they would be on regular salary.
A tax-free reasonable allowance, by contrast, does not appear on the T4 at all. It is paid outside the payroll withholding stream, often on a separate expense cheque, and is neither reported nor subject to source deductions. The employer keeps kilometre logs on file for at least six years in case of CRA review.
Employees who see a large Box 40 amount should not panic. It means the allowance was treated as taxable, but does not automatically mean the allowance was structured incorrectly, and it does not close the door on recovering the tax through the T1 deduction path covered below.
» Step-by-Step: How to Check If Your Allowance Is Being Handled Correctly
The five steps below apply equally to an employee auditing a pay stub and an employer auditing a policy. Work through them in order.
- 1Confirm the structureRead the employment contract or vehicle policy. Is the payment based on kilometres, or a fixed monthly amount? A fixed amount is generally taxable.
- 2Compare the rateIf per-kilometre, check the rate against the 2026 CRA figures (73 cents / 67 cents). Rates above make the excess taxable; well below can also fail the reasonableness test.
- 3Rule out double paymentConfirm there is no fuel card, gas reimbursement or insurance top-up for the same driving. If both exist, both payments are usually taxable.
- 4Read the T4Compare Box 14 against expected salary. Any gap is often explained by Box 40. If a tax-free allowance is showing up in Box 40, ask payroll why.
- 5Request Form T2200If the allowance is genuinely taxable, ask for a signed T2200. Our CRA audit business checklist covers the wider documentation an accountant reviews.
» Common Mistakes Employers and Employees Make
Six mistakes come up repeatedly when Ontario employers set a vehicle policy or employees read their T4. Any one can convert an intended tax-free benefit into taxable income for the employee and a payroll reassessment for the employer.
- ›Paying a flat monthly allowance and treating it as tax-free. A fixed payment fails the CRA’s first condition because it is not based on actual kilometres driven, and the full amount is taxable no matter how the budget was calculated.
- ›Adding a fuel card or gas reimbursement on top of a per-kilometre allowance. The CRA treats the two payments as double coverage, and both can end up taxable.
- ›Skipping the kilometre log. Without a written log the CRA cannot verify the allowance was based on business driving, and the payment is often reassessed as a taxable benefit.
- ›Rolling parking, tolls or ferry charges into the per-kilometre rate. These costs sit outside the reasonable rate and should be reimbursed separately against receipts.
- ›Paying above the CRA rate without treating the excess as taxable. Employers can pay more than the published cents per kilometre, but the excess must be reported and withheld on as employment income.
- ›Owner-managers paying themselves a personal-use vehicle allowance without proper documentation. This is a common trigger in small-business payroll audits, covered in our review of common CRA audit mistakes small businesses make.
» What to Do If Your Allowance Is Taxable: Form T2200 and T1 Recovery
If your car allowance is taxable, you can recover most of the tax by claiming your actual motor vehicle expenses on your T1 return. Ask the employer for a signed Form T2200, Declaration of Conditions of Employment, keep a kilometre log for the year, and hold on to receipts for fuel, insurance, repairs, licence fees, and lease or capital cost allowance on the vehicle itself.
The rule to remember is that you cannot double-dip. Expenses already reimbursed tax-free cannot be deducted again on the T1. The deduction path is designed for employees whose allowance was taxable, not those whose allowance was already tax-free. Our companion article on figuring out home-office and other employment deductions covers the T2200-linked deductions that follow the same logic.
