Business Expenses

General Deductibility

All reasonable expenses incurred to earn business income are deductible for tax purposes, with specific restrictions based on expense type.

Meals & Entertainment

  • A maximum of 50% of meal and entertainment costs can be claimed.
  • Includes dining with clients or business-related entertainment directly tied to earning income.

Automobile Expenses

  • Deductible costs: fuel, maintenance, repairs, insurance, and licensing fees.
  • Depreciation (or lease payments) can be claimed within prescribed limits.
  • Only the business-use portion is deductible, calculated as business kilometers driven divided by total kilometers.
  • Note: Commuting between home and business premises is not deductible.
  • Maintain detailed mileage logs to support claims.

Home Office Expenses

  • Deductible if your home is your principal business location or a dedicated space for business and client meetings.
  • Eligible expenses: mortgage interest, rent, property taxes, insurance, utilities, repairs, and maintenance.
  • Deduction is based on the proportion of business space relative to total home space.
  • Special rules apply in Québec.
  • Claiming depreciation (CCA) on the business portion may impact your principal-residence exemption when selling.
  • The total home office expense deduction cannot exceed business income but can be carried forward.

Conventions

  • Up to two business-related conventions can be claimed annually.
  • Must be held at a location relevant to your business or professional field.
  • Meals and entertainment at conventions are subject to the 50% deductibility limit.

Capital Assets (Depreciation/CCA)

  • Tangible and intangible assets used in your business can be depreciated via Capital Cost Allowance (CCA).
  • Examples: vehicles, equipment, furniture, intellectual property.
  • CCA follows a declining-balance method with deduction rates based on asset class.
  • Only assets “available for use” in the business during the tax year are eligible.
