🏠 How to Claim Home Office Expenses in Ontario for the 2025 Tax Year
Working from home continues to be a common practice for many professionals in Toronto and across Ontario. If you've used a portion of your home for work purposes, you may be eligible to claim home office expenses on your 2024 tax return (filed in 2025). Here's an updated guide tailored for Ontario residents.
✅ Eligibility Criteria
You can claim home office expenses if you meet one of the following conditions:
You worked from home more than 50% of the time for at least four consecutive weeks in the year due to your employment conditions.
You used your home workspace exclusively to earn employment income and regularly met clients, customers, or other people in the course of your employment duties.
For self-employed individuals, the workspace must be your principal place of business or used exclusively to earn business income and meet clients.
🧾 Eligible Expenses
Eligible expenses you can claim include:
Utilities (electricity, heat, water)
Home maintenance and minor repair costs
Rent (for tenants)
Property taxes
Home insurance
Mortgage interest (self-employed individuals only)
Internet access fees
Note: Salaried employees cannot claim mortgage interest or capital expenses.
📐 Calculating Your Claim
Determine the percentage of your home's total area used for work. For example, if your home office occupies 200 square feet of a 2,000-square-foot home, you can claim 10% of eligible expenses.
If the workspace is not used exclusively for work (e.g., a dining room), calculate the percentage of time it's used for work-related activities.
