Enter the business kilometres you have driven this year to see the tax-free allowance at the CRA reasonable per-kilometre rates: a higher rate on the first 5,000 km, a lower one on every kilometre after, and 4¢ more per kilometre in Yukon, the Northwest Territories and Nunavut. Rates are current for the 2025 tax year.
Your kilometres
How it works. CRA publishes two per-kilometre rates each year: one for the first 5,000 business kilometres and a lower one for every kilometre after that. Driving in the three territories earns an extra 4¢ on both bands. The calculator multiplies your kilometres through the two tiers and adds the bands together — that total is the most an employer can pay per kilometre without the allowance becoming taxable income.

These are the 2025 tax year CRA reasonable automobile allowance limits. A kilometre log — date, destination, purpose and distance for each trip — is what defends the claim if CRA ever asks; without one, even a correctly-rated allowance is hard to support.

When the per-kilometre allowance applies
The per-kilometre rates are CRA’s definition of a reasonable automobile allowance. An employer who reimburses an employee for business driving at or below these rates, based solely on actual business kilometres, pays a tax-free allowance — nothing lands on the T4. Pay a flat monthly car allowance instead, or a per-kilometre rate above the limits, and the whole amount becomes taxable employment income. The two-tier structure rewards the first 5,000 kilometres at 72¢ and everything after at 66¢, and driving in Yukon, the Northwest Territories or Nunavut adds 4¢ to both bands.
If you are self-employed, this rate is not your deduction. You claim the actual costs of running the vehicle — fuel, insurance, maintenance, licence, capital cost allowance — prorated by the business share of total kilometres driven. Either way, the kilometre log is the foundation: good bookkeeping keeps it alongside the receipts so the claim survives review.
What this calculator does not cover
It does not compare the allowance to the actual-expense method, which can produce a larger claim for expensive-to-run vehicles — that comparison needs your real operating costs. Parking fees and toll charges incurred on business trips are also outside the per-kilometre rate and are claimable separately with receipts.

| Band | Provinces | Territories |
|---|---|---|
| First 5,000 km | $0.72 | $0.76 |
| Over 5,000 km | $0.66 | $0.70 |
