Questions
How do self-employed people claim car expenses in Canada?
Add up the year’s vehicle costs, then multiply by business kilometres ÷ total kilometres. Business parking and tolls are claimed in full. Report it on form T2125.
Do I need a mileage log?
Yes. CRA expects a logbook with date, destination, purpose and kilometres for each business trip. After one full year, a 3-month sample year can be used if your use is similar.
Is driving to my office a business trip?
No. Going from home to your regular place of business is personal. Trips to clients, suppliers or a market are business.
Can I use the per-kilometre rate instead?
The CRA per-km rates are for allowances an employer pays. Self-employed people claim the business part of actual costs, as this calculator does.
