Expense Optimization for Consultants: What You Can (and Cannot) Deduct
A complete guide to tax deductions for independent consultants in Canada - home office, travel, and meal expenses.
Consultants don’t have heavy machinery or retail inventory - their tax optimization is almost entirely about capturing the right expenses, in the right categories, with the right documentation. In the eyes of the CRA, a "missing receipt" isn’t an expense; it’s a personal draw.
The 2026 Deduction Checklist
| Category | Deductible? | 2026 Strategy / Notes |

| Home office (BUH) | Yes - pro-rated | Must be your principal place of business |
| Mortgage interest | Yes - pro-rated | Principal is NOT deductible; interest only |
| Utilities & Internet | Yes - pro-rated | 100% deduction for a dedicated business line |

| Subcontractors | Yes | Must collect HST IDs if they bill >$30k |
Home Office: The Workhorse Deduction
To qualify for Business-Use-of-Home (BUH) expenses, the space must be your principal place of business OR used exclusively for earning income and used on a regular/continuous basis for meeting clients.
Numerical Example: The 15% Calculation Imagine you use a 300 sq. ft. room in your 2,000 sq. ft. home as a dedicated office. Your "Business Use Percentage" is 15%.
- Mortgage Interest: $24,000
- Property Taxes: $6,000
- Utilities/Insurance: $5,000
- Total Annual Costs: $35,000
- Tax Deduction: $35,000 × 15% = $5,250
Meals: The "Rule of Three"
50% of meals is deductible only when there’s a documented business purpose. The CRA is aggressive here. You must have:
- 01The Itemized Receipt: Not just the debit terminal slip. The CRA wants to see if you bought alcohol (often questioned) or if it was a family-sized meal.
- 02The Who: The name of the client or prospect.
- 03The Why: What was the project or opportunity discussed?
Vehicle Expenses: KM vs. Actual
You have two choices for tracking vehicle costs. Most consultants choose "Actual Expenses" pro-rated by mileage.
| Metric | Required Documentation |
|---|---|
| The Logbook | Date, destination, purpose, and KM for every business trip. |
| The Expenses | Fuel, repairs, insurance, lease payments/CCA, and parking. |
Example: If you drive 20,000km total and 5,000km was for clients, you deduct 25% of all car-related costs.
