If you work from home — whether you\’re self-employed, a contractor, or an employee with a signed T2200 — you may be able to deduct a portion of your household costs. Here\’s how it works.
Who Qualifies
Self-employed individuals can claim home office expenses if they use the space regularly and exclusively for business. Employees need a completed T2200 form from their employer.
What You Can Claim
- A percentage of rent or mortgage interest
- Utilities (heat, electricity, water)
- Home internet (business-use portion)
- Maintenance and minor repairs to the workspace
How to Calculate the Percentage
The most common method is dividing your workspace\’s square footage by your home\’s total square footage. If your office is used part-time, you\’ll also need to prorate by hours used.
Getting this calculation right matters — overclaiming is a common audit trigger. Our team can walk through your specific setup during a consultation.
