Comprehensive List of Deductible Expenses
A technical breakdown of eligible costs for Canadian remote workers and self-employed professionals. Understand what constitutes a valid business expense under current CRA regulations.
Regulatory Framework for Home Office Costs
The Canada Revenue Agency (CRA) permits the deduction of specific expenses related to the maintenance and operation of a workspace within a primary residence. To qualify, the space must be the individual's principal place of business or used exclusively for earning income and meeting clients on a regular basis. It is critical to differentiate between "salaried employees" and "commission-based employees," as the latter have a broader scope of eligible deductions.
All claims must be supported by a completed T2200 form (Declaration of Conditions of Employment) signed by the employer. For self-employed individuals, these expenses are reported via Form T2125. Proper categorization is essential to avoid audits; expenses must be prorated based on the area of the workspace relative to the total finished area of the home. For more details on who qualifies, consult our Home Office Eligibility Requirements.
The following sections provide a granular look at the specific line items that can be included in your tax return. Failure to provide accurate documentation, such as receipts and utility bills, can lead to the denial of claims during a standard review process.
Section 01
Utilities and Operational Costs
Water and Sewage
Municipal water service fees and sewage disposal costs are eligible for proration based on the square footage of the office.
View Requirements →Home Internet
The "reasonable" portion of your monthly internet service fee used for work purposes. Note that connection fees are generally not deductible.
View Requirements →Maintenance and Repair Costs
Maintenance expenses refer to the costs of keeping your home in good repair. If a repair is performed specifically on the room used for the office, 100% of that cost may be deductible. However, if the repair benefits the entire house (e.g., furnace repair or roof maintenance), the cost must be prorated.
- Minor Repairs: Fixing a window, repairing a leak, or replacing light fixtures in the office area.
- Cleaning Supplies: Pro-rated cost of cleaning products used for the maintenance of the workspace.
- Excluded Items: Capital expenses such as replacing a furnace or a roof are generally not deductible as current expenses.
Office Supplies & Consumables
Stationery, ink cartridges, and other consumable items used directly for employment purposes are fully deductible. Unlike utilities, these do not require square-footage proration if they are used exclusively for work. Keep detailed records of all purchases throughout the fiscal year.
100% Deductible for Supplies
0% Deductible for Furniture
Rent vs. Mortgage: Critical Differences
One of the most common points of confusion involves housing payments. If you rent your home, you can deduct the portion of your rent that relates to your workspace. However, if you own your home, the rules are significantly more restrictive for salaried employees.
| Expense Type | Salaried Employee | Commission Employee |
|---|---|---|
| Monthly Rent | Yes (Pro-rated) | Yes (Pro-rated) |
| Mortgage Interest | No | No |
| Property Taxes | No | Yes (Pro-rated) |
| Home Insurance | No | Yes (Pro-rated) |
*Note: Mortgage principal payments are never deductible. For a detailed breakdown of how to calculate these values, visit our Home Office Calculation Guide.
