Canadian employees who work from home may deduct home office expenses from employment income under certain conditions. The deduction is available only if the employer requires the work-from-home arrangement, and the workspace is used more than 50% of the time for work or exclusively for meeting clients. The CRA eliminated the temporary flat-rate method after the 2022 tax year — for 2023 and onward, employees must use the detailed method with Form T2200 from their employer.
Quick Answer
For 2025, an employee who works from home and uses a 200 sq ft home office in a 1,200 sq ft home (16.7% of total space) with total housing costs of $28,800/year ($2,400/month rent) can deduct 16.7% x $28,800 = $4,810 from employment income — reducing taxes by approximately $2,000 at a 43% marginal rate.
Eligible Expenses for Employees
Employees can deduct home office expenses proportional to workspace use. Eligible expenses depend on whether the employee is a salaried employee or a commission employee:
Salaried employees (most employees): Rent, electricity, heat, water, internet access fees, cleaning materials, and minor repairs (not capital improvements). Cannot deduct mortgage interest, property taxes, or home insurance.
Commission employees: All of the above, plus mortgage interest, property taxes, and home insurance proportional to the workspace.
How the Deduction Is Calculated
Step 1 — Workspace percentage: Square footage of the workspace divided by total home square footage. Or, for rooms used exclusively as offices, count the rooms.
Step 2 — Work time percentage: If the space is not used exclusively for work, multiply by the percentage of time it is used for work (e.g., 8 hours/day, 5 days/week = 24/168 hours = 23.8% of the week).
Step 3 — Apply to eligible expenses: Multiply workspace percentage x work time percentage x total eligible annual expenses.
Step 4 — Apply employment use limit: The deduction cannot exceed employment income from the employer who required the work-from-home arrangement.
Form T2200
The employer must complete Form T2200 (Declaration of Conditions of Employment) certifying that the employee was required to work from home and was required to pay home office expenses. The employee keeps the T2200 — it does not need to be filed with the T1 but must be available if CRA requests it.
Self-Employed Home Office
Self-employed individuals (sole proprietors, freelancers) claim home office expenses as business expenses on Form T2125 (Statement of Business Activities). The rules differ from the employee deduction: mortgage interest and capital cost allowance (CCA) on the home’s business portion may be claimed, subject to CCA rules. The business-use portion must be the principal place of business or exclusively used for meeting clients.

Employee home office expenses are governed by ITA section 8(1)(i) and 8(13). The T2200 requirement is set under ITA s.8(10). The flat-rate method was a temporary CRA administrative policy (2020-2022) not enshrined in the ITA.

Frequently asked questions
- Can I claim home office expenses as an employee in Canada?
- Yes, if your employer required you to work from home and complete Form T2200. For 2023 and onward, the detailed method applies — you calculate actual eligible expenses proportional to workspace use. The temporary flat-rate method (introduced for COVID-19) was eliminated after the 2022 tax year.
What is Form T2200?
Form T2200 (Declaration of Conditions of Employment) is completed by your employer and certifies that you were required to work from home and incur home office expenses. You keep the form — do not send it with your T1. If CRA audits your home office claim, you must produce the T2200. Ensure your employer completes it before the tax filing deadline.
What expenses can a salaried employee deduct for home office?
Salaried employees can deduct: rent, electricity, heat, water, internet access fees, cleaning materials, and minor maintenance costs (not capital improvements) — all proportional to workspace use. Salaried employees cannot deduct mortgage interest, property taxes, or home insurance. Commission employees can also deduct these additional costs.
How do I calculate the workspace percentage for home office?
Workspace % = area of home office (sq ft) / total area of home (sq ft). If your home office is 150 sq ft in a 1,000 sq ft home, the workspace is 15%. If the space is not exclusively used for work (e.g., a dining room used as an office part-time), also multiply by the time percentage used for work.
Can I deduct internet at home for work?
Yes. Internet access fees are explicitly listed as an eligible home office expense for employees under CRA's updated guidance for the 2023+ tax years. Claim the workspace percentage of your annual internet bill. If internet is used for both work and personal purposes, claim only the work-use proportion.
What is the limit on the home office deduction?
The home office deduction cannot exceed your employment income from the employer who required the arrangement. You cannot create or increase a loss from employment using home office expenses. Any excess can be carried forward to the following tax year if the same employment conditions continue.
Can self-employed people claim home office expenses?
Yes. Self-employed individuals claim home office expenses on Form T2125 (Statement of Business Activities). The deduction is more generous than for employees — you may claim mortgage interest and, depending on ownership situation, capital cost allowance on the business-use portion of the home. The workspace must be the principal place of business or exclusively used for client meetings.
Can I deduct rent for a home office?
Yes. Rent is an eligible expense for employee home office deductions. Claim the workspace percentage of annual rent paid. For a $2,000/month rental with a 15% workspace, the eligible rent portion is $2,000 x 12 x 15% = $3,600 per year.
Does my employer have to agree to the T2200?
Your employer must complete the T2200 in good faith — it certifies conditions of employment that actually applied. If your employer genuinely required you to work from home (and did not reimburse home office expenses), they should sign the T2200. Employers cannot be compelled to sign if the conditions were optional or if they fully reimbursed your expenses.
What happened to the $2/day flat-rate home office deduction?
The temporary flat-rate method ($2/day, maximum $500 for 2022) was a CRA administrative accommodation during COVID-19. It was available for 2020, 2021, and 2022 tax years only. Starting with the 2023 tax year, all employees must use the detailed method with a completed T2200 from their employer.
