More than 4 million Canadians now work from home at least part-time, and many homeowners have the unique advantage of deducting a portion of their housing costs through the CRA’s home office deduction. Whether you are an employee working remotely or self-employed running a business from home, a properly set up office saves money on taxes and improves your productivity.

Calculating Your Deduction (Detailed Method)
Step 1: Determine the Percentage
| Method | Calculation |
|---|---|
| Square footage | Office sq ft ÷ total home sq ft |
| Number of rooms | 1 ÷ total number of rooms (if rooms are roughly equal size) |
Example: 150 sq ft office in a 1,500 sq ft home = 10%
Step 2: Calculate Eligible Expenses
| Expense | Annual Amount | Business % (10%) | Deduction |
|---|---|---|---|
| Electricity | $2,400 | 10% | $240 |
| Gas/heating | $1,800 | 10% | $180 |
| Water | $600 | 10% | $60 |
| Internet | $1,200 | 50% (work use portion) | $600 |
| Home insurance | $2,000 | 10% | $200 |
| Maintenance (general) | $1,000 | 10% | $100 |
| Total (employee) | — | — | $1,380 |
| Mortgage interest (self-employed only) | $18,000 | 10% | $1,800 |
| Property taxes (self-employed only) | $4,500 | 10% | $450 |
| Total (self-employed) | — | — | $3,630 |
At a 30% marginal tax rate, the employee saves ~$414 in taxes and the self-employed person saves ~$1,089.

| Chair height | Feet flat on floor; thighs parallel to ground |
| Desk height | Elbows at 90° when typing |
| Keyboard position | Wrists straight, not angled up |
| Lighting | Natural light from the side (not behind the screen); supplement with desk lamp |
| Room temperature | 20–22°C for optimal focus |
Internet Requirements
| Activity | Minimum Speed (Download) | Recommended |
|---|---|---|
| Video calls (1 person) | 5 Mbps | 10+ Mbps |
| Video calls (group) | 10 Mbps | 25+ Mbps |

Home Office and Your Mortgage
| Connection | Details |
|---|---|
| Does not affect mortgage qualification | Lenders do not penalize you for having a home office |
| Does not affect principal residence exemption | As long as you avoid claiming CCA (depreciation) |
| Self-employed income from home | Lenders consider it for qualification using a 2-year average |
| Mortgage interest deduction (self-employed) | The home office portion of mortgage interest is deductible |
| Property value | A well-designed home office adds appeal in the post-pandemic market |
Common Mistakes to Avoid
| Mistake | Why It Is a Problem | Solution |
|---|---|---|
| Claiming CCA on your home | Triggers recapture on sale; can disqualify principal residence exemption | Claim operating expenses only — skip CCA |
| Overclaiming the percentage | CRA audits look for unreasonable workspace percentages | Measure accurately; be conservative |
| Not getting T2200 from employer | Deduction is denied without the form | Request from employer early in the tax year |
| Missing the flat rate as better option | Sometimes $500 flat is more than your detailed calculation | Calculate both; file the higher one |
| Claiming personal internet fully | Must reasonably apportion between personal and work | 40%–60% work use is typical for a full-time WFH employee |
