For employers with drivers in both Canada and the United States, mileage reimbursement can look similar on the surface.
Employees use personal vehicles for business, track their mileage, and receive reimbursement from their employer.
The tax rules behind those payments are different.
In the U.S., employers may use the IRS standard mileage rate, a Fixed and Variable Rate (FAVR) program, or other reimbursement arrangements that meet applicable IRS requirements.
In Canada, the Canada Revenue Agency (CRA) has its own rules for determining when a per-kilometre vehicle allowance can be treated as non-taxable.
For organizations managing drivers on both sides of the border, the goal is to build a consistent vehicle program while applying the correct tax rules in each country.
Canada vs. U.S. Mileage Reimbursement at a Glance
The biggest difference is the framework each country uses.
In the U.S., the IRS publishes an optional standard mileage rate. For July 1 through December 31, 2026, the business rate is 76 cents per mile, following a midyear increase from 72.5 cents for the first half of 2026.
The rate can be used for certain business mileage allowances and deductible vehicle costs.
Canada uses kilometres rather than miles and has its own rules for reasonable automobile allowances. For 2026, the CRA-prescribed per-kilometre rates are:
Those numbers should not be compared directly as though one country reimburses more generously. They use different currencies, different units of distance, and different tax frameworks.
How Mileage Reimbursement Works in the U.S.
The IRS standard mileage rate is an optional rate employers may use to determine the amount of certain business mileage allowances that can be treated as substantiated for federal tax purposes.
For 2026, the business rates are:
- 72.5 cents per mile: January 1 through June 30
- 76 cents per mile: July 1 through December 31
The IRS increased the rate midway through 2026 in response to recent increases in fuel prices.
Employers can also reimburse at a different rate. The tax treatment of those payments depends on how the reimbursement arrangement is structured and substantiated.
Under an IRS accountable plan, expenses must have a business connection, employees must adequately account for them within a reasonable period, and employees must return excess reimbursements within a reasonable period.
Reimbursements that meet accountable-plan requirements generally are not treated as wages.
Accurate mileage records therefore remain important. Employees should substantiate details such as business mileage, dates, destinations, and business purpose.
How Mileage Reimbursement Works in Canada
Canada approaches vehicle allowances differently.
The CRA generally considers a per-kilometre automobile allowance reasonable when it is based only on the number of business kilometres driven and the per-kilometre rate itself is reasonable.
When those conditions are met and the allowance otherwise satisfies CRA requirements, it may generally be treated as non-taxable to the employee.
For 2026, the CRA-prescribed per-kilometre rates are:
- Provinces: $0.73/km for the first 5,000 business kilometres and $0.67/km after that
- Territories: $0.77/km for the first 5,000 business kilometres and $0.71/km after that
The prescribed rate is an important benchmark, but CRA guidance also recognizes that a higher or lower rate can sometimes be reasonable depending on the employee’s circumstances.
Factors such as vehicle type, driving conditions, and unusually high local fuel costs may be relevant.
That nuance matters. An allowance that differs from the prescribed rate is not automatically taxable.
The CRA considers whether the allowance is reasonable based on the circumstances and whether the other applicable requirements are satisfied.
IRS vs. CRA Mileage Rates: What’s the Difference?
Both tax authorities provide mileage-related guidance, but employers should treat them as separate systems.
The IRS standard mileage rate is expressed in U.S. dollars per mile and provides an optional method for determining certain business mileage allowances and vehicle expenses.
The CRA prescribed allowance rate is expressed in Canadian dollars per kilometre and helps employers determine whether an automobile allowance for an employee’s use of a personal vehicle can be considered reasonable for Canadian tax purposes.
There is another set of CRA rates that can cause confusion.
The CRA also publishes province- and territory-specific kilometric rates under its Directive on Travel.
Those rates apply to CRA employees and others travelling under that government travel directive.
They are not the general prescribed allowance rates private-sector employers should automatically apply to employees.
For a company operating across North America, one universal cents-per-mile or cents-per-kilometre policy is unlikely to fit both tax systems well.
Where Does FAVR Fit?
U.S. employers also have access to Fixed and Variable Rate (FAVR) reimbursement.
FAVR separates vehicle expenses into two categories: fixed and variable costs.
Fixed costs can include depreciation or lease payments, insurance, registration, and similar ownership expenses. Variable costs include expenses such as fuel, maintenance, oil, and tires.
Instead of applying one national cents-per-mile rate to every employee, a FAVR program can account for factors such as an employee’s location and business mileage.
FAVR programs are subject to specific IRS requirements around driver participation, annual business mileage, vehicle cost, insurance, and other program criteria.
Employers using FAVR should make sure the program is designed and administered according to those requirements.
When the applicable FAVR rules are satisfied, reimbursements can receive favorable tax treatment under the U.S. framework.
Canada does not use the U.S. FAVR tax framework.
Employers with Canadian employees therefore need to design those employees’ vehicle payments around Canadian tax requirements rather than simply extending a U.S. FAVR program across the border.
Do Employers Have to Reimburse Mileage in Canada and the U.S.?
Tax treatment and an employer’s legal obligation to reimburse are separate questions.
At the U.S. federal level, IRS rules primarily determine the tax treatment of mileage reimbursements.
They do not create a universal requirement for every private employer to reimburse employees at the IRS standard mileage rate.
State law can add reimbursement obligations.
Employers with drivers in states such as California, Illinois, and Massachusetts should review the requirements that apply where their employees work.
Canada also has its own employment standards, provincial rules, contracts, and collective agreements that may affect employer obligations.
The CRA guidance discussed here primarily addresses tax treatment rather than creating one nationwide rule requiring every employer to pay the prescribed per-kilometre rate.
For cross-border employers, reimbursement policies should therefore be reviewed from both a tax and employment-law perspective.
What Should a Cross-Border Mileage Reimbursement Program Include?
A North American vehicle program needs enough consistency to be manageable while still accommodating the rules that apply in each country.
Employers should clearly define:
- who is eligible for reimbursement
- how business travel is treated
- how mileage is recorded
- which reimbursement method applies to each driver population
- how payments are reviewed and approved
- what insurance and driver requirements apply
- how state or provincial requirements are handled
Documentation is especially important.
Both U.S. and Canadian tax frameworks place significant weight on substantiating business use of a personal vehicle.
A centralized mileage tracking process can help employers maintain consistent records while applying different reimbursement rules to U.S. and Canadian employees.
One Workforce Doesn’t Require One Reimbursement Method
For organizations with drivers throughout North America, consistency doesn’t have to mean paying every employee according to the same formula.
An employer might use FAVR for an eligible group of U.S. employees who drive regularly for work, Cents-Per-Mile for occasional U.S. drivers, and a CRA-aligned per-kilometre allowance for employees in Canada.
This type of mixed reimbursement strategy allows employers to establish common principles around mileage tracking, documentation, insurance, and administration while using reimbursement methods that fit each driver population and jurisdiction.
The important part is making those differences intentional and clearly documented.
