Canadian employees who work from home can deduct eligible home office expenses against employment income, reducing their taxable income and tax bill. For the 2026 tax year, there are two methods: the flat rate method ($2/day, up to $400, no receipts or employer signature needed) and the detailed method using Form T777 (requires Form T2200 signed by your employer and actual receipts). Self-employed individuals use the detailed method without T2200. The deduction is claimed at Line 22900 on your T1 return.
Quick answer: If you worked from home in 2026 under an employer requirement, you likely qualify. The flat rate method is simpler but capped at $400. If your actual home costs are higher, the detailed T777 method with your employer’s T2200 signature will produce a larger deduction. Self-employed workers are not capped.
Two Methods for Employees
| Method | Maximum Deduction | T2200 Required? | Receipts Required? |
|---|---|---|---|
| Flat rate ($2/day) | $400 (200 days × $2) | No | No |
| Detailed (Form T777) | Based on actual costs | Yes | Yes |
The flat rate method is useful for employees with low actual home office costs or those whose employer will not sign a T2200. The detailed method is almost always better if your actual costs exceed $400 for the year.
Flat Rate Method: Who Qualifies
To use the flat rate method for 2026, you must:
- Have worked from home more than 50% of the time for at least 4 consecutive weeks (due to employer requirement or pandemic protocols)
- Use the workspace to perform your employment duties (not just for occasional work)
How to claim: Simply enter the number of days worked from home (maximum 200) multiplied by $2 on Line 22900 of your T1 return. No supporting documentation is submitted, though the CRA may request records.
Example: Jennifer worked from home 180 days in 2026. Flat rate claim: 180 × $2 = $360
Detailed Method (T777 + T2200): Step-by-Step
Step 1: Get T2200 Signed
Ask your employer (HR or payroll) to complete and sign Form T2200. This confirms:
- You were required to maintain a home office
- You were not reimbursed for home office costs
- The nature of your employment required you to work from home
Step 2: Calculate Your Work-Space Percentage
The eligible portion of home expenses is based on the workspace as a percentage of your home’s total area:
- Dedicated workspace: (workspace area ÷ total home area) × 100
- Example: 150 sq ft home office in a 1,200 sq ft home = 12.5%
If you use the workspace for personal activities as well, you must further limit the claim to reflect actual business use time.
Step 3: Identify Eligible Expenses
| Expense Type | Salaried Employees | Commissioned Employees |
|---|---|---|
| Heat | Yes | Yes |
| Electricity | Yes | Yes |
| Water | Yes | Yes |
| Internet access fees | Yes | Yes |
| Rent (if renting) | Yes | Yes |
| Cleaning materials | Yes | Yes |
| Property taxes | No | Yes |
| Home insurance | No | Yes |
| Mortgage interest | No | No |
| Principal repayments | No | No |
| Capital cost allowance | No | No |
Step 4: Calculate the Deduction
Worked example — Salaried employee:
Marcus earns $75,000 and works 100% from home in a 10% workspace (200 sq ft / 2,000 sq ft home).
Annual eligible home expenses:
- Rent: $24,000/year
- Heat + electricity: $2,400/year
- Internet: $1,200/year
- Cleaning supplies: $300/year
- Total: $27,900
Workspace percentage: 10%
Home office deduction: $27,900 × 10% = $2,790
This deduction reduces Marcus’s employment income from $75,000 to $72,210, saving approximately $690 in federal tax (at a 24.7% marginal rate) plus provincial tax savings.
Important Limits
- The deduction cannot exceed your employment income for the year — it cannot create an employment loss
- Excess amounts carry forward to future years (continued employment in the same conditions)
Self-Employed Home Office Deduction
Self-employed individuals (sole proprietors, freelancers, incorporated professionals) claim home office expenses differently:
- No T2200 required — you self-certify through your books and records
- Claim on Form T2125 (Statement of Business or Professional Activities)
- Same list of eligible expenses, same proportional calculation
- Mortgage interest IS deductible for self-employed (unlike employees)
- Capital Cost Allowance on the home is technically permitted but creates capital gains exposure on sale — rarely advisable
Self-employed owners should consult a tax professional before claiming CCA on their principal residence, as it partially removes the principal residence exemption.
Record Keeping
Keep these records for 6 years from your filing date:
- T2200 (keep on file — not submitted with return)
- Receipts for all claimed expenses
- Floor plan or measurements confirming workspace dimensions
- Records showing number of days worked from home
Interaction with Provincial Tax Credits
British Columbia, Ontario, and other provinces calculate provincial income tax on your net income — so a federal home office deduction also reduces provincial income tax. The combined federal and provincial tax saving is approximately 25–50% of the deduction depending on your province and income level.

The home office deduction is one of the most valuable and commonly overlooked deductions for remote workers. If you paid more than $400 in eligible home costs in 2026, get a T2200 from your employer and file the detailed T777 method — it can save several hundred to over a thousand dollars annually.
