Whether you are self-employed, a salaried employee, or a commissioned salesperson working remotely, you may be able to deduct home office expenses on your Canadian tax return. The rules differ depending on your employment type.
Last updated: April 2026
Who Can Claim Home Office Expenses?
To claim work-from-home expenses in Canada, you must meet one of these conditions:
- Your home is where you mainly (more than 50% of the time) do your work, OR
- You use the space exclusively for work and use it on a regular and continuous basis for meeting clients, customers, or other people related to your work
The deduction is based on the percentage of your home used for work. If your office is 200 sq ft in a 2,000 sq ft home, your claim is 10% of eligible expenses.
Flat Rate Method vs. Detailed Method
CRA offers two methods for employees:
Temporary Flat Rate Method
Note: The temporary flat rate method ($2/day, up to $500) was available for 2020-2022 tax years only. It is no longer available starting with the 2023 tax year. You must use the detailed method going forward.
Detailed Method (Current Method)
Under the detailed method, you calculate the actual expenses related to your home office. This requires a completed T2200 (Declaration of Conditions of Employment) signed by your employer.
What Can You Deduct? (By Employment Type)
| Expense | Salaried Employee | Commissioned Employee | Self-Employed |
| Rent | Yes | Yes | Yes |
| Electricity | Yes | Yes | Yes |
| Heat | Yes | Yes | Yes |
| Water | Yes | Yes | Yes |
| Internet (work portion) | Yes | Yes | Yes |
| Maintenance & repairs | Yes | Yes | Yes |
| Office supplies | Yes | Yes | Yes |
| Property taxes | No | Yes | Yes |
| Home insurance | No | Yes | Yes |
| Mortgage interest | No | No | Yes |
| Capital Cost Allowance | No | No | Yes (use caution) |
CCA warning for self-employed: Claiming Capital Cost Allowance on your home can trigger a taxable capital gain when you sell, even on your principal residence. Most accountants advise against claiming CCA for this reason.
How to Calculate Your Home Office Deduction
Step 1: Determine Your Work-Use Percentage
Divide your office space by total home square footage. If you use the space part-time, prorate further.
Example: 150 sq ft office / 1,500 sq ft home = 10%
Step 2: Total Up Eligible Expenses
| Expense | Annual Amount |
|———|————–|
| Rent | $18,000 |
| Electricity | $1,800 |
| Heat | $1,200 |
| Internet | $960 |
| Home insurance | $1,440 |
| Total | $23,400 |
Step 3: Apply Your Percentage
$23,400 x 10% = $2,340 home office deduction
Important Rules to Know
You Cannot Create a Loss
Home office expenses for employees cannot exceed your employment income. For self-employed individuals, home office expenses cannot create or increase a business loss. However, unused amounts can be carried forward to the next year.
Employer Reimbursements
If your employer reimburses you for home office expenses, you cannot also claim those same expenses as a deduction. The T2200 form will indicate whether your employer provides any reimbursement.
Keep Your Records
Maintain all receipts and invoices for at least six years. CRA can audit your claim and will require documentation.
Frequently Asked Questions
Can I claim home office expenses working from home in Canada?
Yes, if your home is where you mainly do your work (more than 50%) or you use a dedicated space exclusively and regularly for meeting clients. Employees need a T2200 form from their employer. Self-employed individuals report directly on their T2125.
What is the maximum home office deduction in Canada?
There is no fixed dollar cap. Your deduction is based on the actual percentage of your home used for work multiplied by eligible expenses. The only limit is that the deduction cannot exceed your related income (you cannot create a loss).
Do I need a T2200 to claim home office expenses?
Employees need a T2200 signed by their employer. Self-employed individuals do not need a T2200 since they report home office expenses on their T2125 business income form.
