How to Properly Claim Your Home Office on Your Taxes
If you work from home, you might be able to deduct some of your home expenses — but only if you meet the CRA’s rules.
✅ The workspace must be:
- Where you principally (more than 50% of the time) perform your work, OR
- Used on a regular and continuous basis for meeting customers or clients.
✅ Eligible expenses may include:
- Heat, electricity, light bulbs, minor repairs, cleaning supplies
- A reasonable portion of rent (if you rent your home)
- For sole proprietors or commission employees: a reasonable part of property taxes, home insurance, and mortgage interest (rules vary)
🚫 What you can’t claim:
- If you’re a regular employee: no mortgage interest, capital cost allowance, or the rental value of a workspace if you own your home.
- Supplies do not include phone line service charges, special clothing, or tools.
🔢 How to calculate:
1️⃣ Figure out the % of your home’s floor space that your office takes up.
2️⃣ Figure out what % of time you use it for work vs personal use.
3️⃣ Multiply to get the portion you can claim.
Example: If your office is 10% of your home and used 60% for work — claim 6% of eligible expenses.
💡 Tip: You can’t claim more than your annual income from that work, and these expenses can’t create or increase a loss. If you can’t use them all in one year, you may carry them forward (for employees, only if it’s the same employer).
Need help figuring this out? We’re here to help you get it right and stay CRA-compliant.
