Working from home has become a permanent reality for millions of Canadians, and the CRA allows eligible workers to claim a deduction for home office expenses on their personal tax return. Whether you are an employee who works remotely or a self-employed individual running a business from home, understanding how to properly claim these expenses can result in meaningful tax savings. At BOMCAS Canada, our Professional Tax Accountants help clients across Edmonton and all of Canada maximize their home office deductions while staying fully compliant with CRA rules.
Who Can Claim Home Office Expenses?
Both employees and self-employed individuals can claim home office expenses, but the rules differ significantly between the two groups. The key requirement for employees is that their employer must certify that they were required to work from home as a condition of employment.
For employees, you can claim home office expenses if:
- You were required by your employer to work from home under a written agreement or as a condition of employment
- You worked from home more than 50% of the time for at least four consecutive weeks in the year, OR you used the home office space exclusively for work and regularly met clients or customers there
- Your employer has provided you with a completed and signed T2200 (Declaration of Conditions of Employment)
For self-employed individuals, you can claim home office expenses if you use part of your home regularly and exclusively (or primarily) for business purposes.
Home Office Expenses for Employees
Employees claiming home office expenses must use the detailed method for the 2023 and later tax years. The temporary flat rate method ($2 per day, up to $500) was a COVID-era measure that was discontinued after the 2022 tax year.
Under the detailed method, you calculate the actual percentage of your home that is used for work and apply that percentage to your eligible home expenses. You must keep all receipts and have a completed T2200 from your employer.
Employees can deduct the following expenses under the detailed method:
- Rent (if you rent your home)
- Electricity, heat, water, and home internet
- Maintenance and minor repairs
- Office supplies used for work
- Monthly fees for a basic cell phone plan (the portion used for work)
Employees generally cannot deduct mortgage interest, property taxes, home insurance, or capital cost allowance on their principal residence.
Home Office Expenses for Self-Employed
Self-employed individuals have more flexibility when claiming home office expenses. You can claim a broader range of expenses, and you do not need a T2200. Instead, you report home office expenses on Form T2125 (Statement of Business or Professional Activities).
Self-employed individuals can deduct:
- Rent or mortgage interest
- Property taxes
- Home insurance
- Electricity, heat, water, and internet
- Maintenance and repairs
- Capital cost allowance (CCA) on the business-use portion of your home (use with caution — this can affect your principal residence exemption)
The home office must be your principal place of business or used exclusively for meeting clients, customers, or patients on a regular and continuous basis.

How to Calculate Your Home Office Deduction
The home office deduction is calculated by determining the percentage of your home used for work and applying that percentage to your total eligible expenses. The most common method is to divide the area of your home office by the total area of your home.
For example, if your home office is 150 square feet and your total home is 1,500 square feet, your work-use percentage is 10%. If your total eligible home expenses for the year are $24,000, your home office deduction would be $2,400.
If you use the same space for both personal and work purposes (such as a dining room table), you must further reduce the deduction to reflect only the time the space is used for work. The CRA expects the calculation to be reasonable and well-documented.
The T2200 Form Explained
The T2200 (Declaration of Conditions of Employment) is a form completed and signed by your employer that certifies you were required to work from home as a condition of your employment. Without a signed T2200, employees cannot claim home office expenses using the detailed method.
Key points about the T2200:
- Your employer must sign the T2200 — you cannot sign it yourself
- You do not submit the T2200 with your tax return, but you must keep it in case the CRA requests it
- The T2200 must accurately reflect your employment conditions for the year
- If your employer refuses to sign a T2200, you cannot claim home office expenses as an employee
Common Mistakes to Avoid
Our tax accountants at BOMCAS Canada frequently see the following mistakes when clients claim home office expenses:
- Claiming the entire home: Only the area used exclusively for work qualifies. You cannot claim your entire home as a home office.
- Missing the T2200: Employees who claim home office expenses without a signed T2200 will have their claim denied by the CRA.
- Claiming capital improvements: Renovations and capital improvements are not deductible as home office expenses. Only current expenses (repairs and maintenance) qualify.
- Exceeding employment income: Employees cannot use home office expenses to create or increase a loss from employment. The deduction is limited to your employment income from that employer.
- No receipts: Always keep receipts for all home expenses claimed. The CRA may request documentation during a review or audit.

How the CRA Audits Home Office Claims
The CRA pays close attention to home office deductions, particularly for employees and self-employed individuals claiming large amounts. During an audit, the CRA will typically request documentation including floor plans or measurements of your home and office space, utility bills, mortgage statements or lease agreements, and records showing the office is used exclusively (or primarily) for earning income. The CRA may also ask for a description of your work activities and why working from home was required.
To protect yourself in the event of an audit, maintain a dedicated workspace that is clearly defined and used only for work. Keep all receipts and bills for home expenses for at least six years. Take photos of your home office setup. Ensure your employer has completed Form T2200 or T2200S if you are claiming as an employee, and keep a copy on file.
Home Office Expenses for Incorporated Business Owners
If you operate your business through a corporation, the rules for home office expenses are different. Your corporation can pay you a reasonable rent for the use of your home office under a written lease agreement. This rent is deductible to the corporation as a business expense. However, the rent you receive is taxable income to you personally, and you must report it on your personal tax return.
Alternatively, the corporation can reimburse you directly for the home office expenses you incur on its behalf. This reimbursement is not taxable to you as long as it is reasonable and supported by receipts. The corporation deducts the reimbursement as a business expense. This approach is often simpler than charging rent and avoids the need to track rental income on your personal return.
