How Self-Employed Canadians Deduct Tesla Expenses on Form T2125
If you're self-employed, you deduct only the business-use percentage of your Tesla's costs — electricity, insurance, maintenance, lease and capital cost allowance — on Form T2125. That percentage comes from a logbook of business kilometres versus total kilometres. Electricity is treated as your fuel cost, and a Tesla can qualify for the enhanced zero-emission-vehicle CCA (Class 54, $61,000 cost limit), but neither changes the need for a logbook.
What Tesla costs can you deduct, and how much?
Self-employed individuals and partners report vehicle costs on Form T2125, Statement of Business or Professional Activities. You can deduct fuel — for a Tesla, that's electricity — plus insurance, maintenance and repairs, licence and registration, interest or lease costs, and capital cost allowance. But you deduct only the business-use proportion of each; the personal portion is disallowed. So everything hinges on your business-use percentage, which is business kilometres divided by total kilometres for the year. Get the percentage wrong and every line of your vehicle expenses is wrong with it.
How is a Tesla's electricity and CCA treated?
Electricity used to charge your Tesla stands in for gasoline as your fuel cost, so the business share of your home and public charging is deductible. Keep records that let you attribute charging to the vehicle. A Tesla is a zero-emission vehicle, so it can qualify for the enhanced first-year capital cost allowance under Class 54, subject to a $61,000 cost limit (before taxes) on the amount you can depreciate. The enhanced CCA is a genuine EV advantage, but it doesn't loosen the record-keeping rule: you still apply your logbook-based business-use percentage to the CCA you claim.
Why is the logbook the load-bearing document?
The CRA states the best evidence of business use is an accurate logbook maintained for the whole year, recording date, destination, purpose and kilometres for each business trip, plus start and end odometer readings. You can use the full-logbook method or, after a representative 12-month base year, the simplified three-month sample method — provided your business use stays within 10 percentage points of the base-year period. On audit, a reconstructed or estimated log is routinely rejected and your vehicle claims can be cut. Keep the logbook and supporting receipts for six years from the end of the tax year.
Company car or self-employed vehicle — which rules apply?
These T2125 rules are for a vehicle you own or lease and use in your own business. They're distinct from the employer-provided-car regime, where personal use is a taxable benefit (standby charge plus operating benefit) on your T4. If you're an owner-manager, be clear about which regime your vehicle falls under, because the calculations and the >50% business-use tests differ. Either way, the underlying evidence is the same: a clean, contemporaneous kilometre log.
FAQ
Can I deduct the electricity to charge my Tesla?+
Yes — for a self-employed vehicle, electricity is your fuel cost, and the business-use percentage of your charging is deductible on T2125. Keep records that tie the charging to the vehicle.
What CCA class does a Tesla fall under?+
A Tesla can qualify for the enhanced zero-emission-vehicle capital cost allowance in Class 54, with a $61,000 cost limit on the depreciable amount. You still apply your business-use percentage to the claim.
What if I don't have a logbook?+
The CRA can disallow the personal portion and, without adequate records, reduce or deny your vehicle deductions on audit. The burden of proof is on you.
On a T2125, your Tesla deduction is only as strong as your business-use percentage — and that comes straight from your logbook. Join the Odoproof waitlist to capture every business kilometre automatically and claim what you're owed.
