Business Expense Checklist for Canadian Corporations
Every dollar of legitimate expense you record lowers your taxable income — and every dollar you forget is tax you did not need to pay. This business expenses Canada corporation checklist walks through the deductions Canadian corporations and owner-managers claim most often, the ones with special rules (meals, vehicles, home office), and the records the CRA expects. Use it to review your books before year-end so nothing deductible is left on the table.
The rule behind every deduction
To be deductible, an expense generally must be incurred to earn business income, be reasonable in the circumstances, and be supported by a record. Personal costs are not deductible, and some business costs (like meals or a vehicle used partly for personal trips) are only partly deductible. Get those distinctions right and the checklist does the rest.
Fully deductible operating expenses
These are the everyday costs of running the company. When they are ordinary, reasonable, and documented, they are generally 100% deductible. Clean bookkeeping is what makes claiming them painless at year-end.
Expenses with special rules
Some of the most common business expenses Canada corporation owners claim are only partly deductible or follow their own formula. Getting these right protects the deduction if the CRA ever asks.
| Expense | Deductible portion | Key rule |
|---|---|---|
| Business meals & entertainment | Generally 50% | Must have a business purpose; keep who/what/why on the receipt. |
| Motor vehicle | Business-use % | Deduct based on business kilometres over total kilometres; keep a mileage log. |
| Home office (owner) | Business-use % of the home | Available where the space is the principal place of business or used regularly to meet clients. |
| Capital assets (equipment, vehicles) | Over time via CCA | Claimed as capital cost allowance by class, not fully in year one. |
| Gifts & promotional items | Varies | Promotional items differ from entertainment; treatment depends on the item. |
Owner-manager and startup costs to remember
Vehicle log
Track business versus personal kilometres. Without a log, the CRA can reduce your claim to what it thinks is reasonable.
Home office share
Measure the workspace as a percentage of your home and apply it to utilities, insurance, and maintenance.
Startup & incorporation costs
Certain incorporation and startup expenses are deductible or eligible for capital treatment — capture them early.
Owner reimbursements
Business costs paid personally should be reimbursed and recorded, so the corporation gets the deduction cleanly.
Training & dues
Professional development, licences, and membership dues related to the business are typically deductible.
Bad debts
Amounts previously included in income that become uncollectible may be written off as a deduction.
