Home office expenses: Here's how you could save on taxes if you worked remotely this year

Did you provide phone or virtual care to your patients last year? You may be entitled to some additional tax savings for working from home.

Your employment status will determine what expenses you can deduct and how you go about it:

  • If you’re an employee: If you worked from home in 2022, you may be able to deduct home-office expenses using one of two approaches, one of which is a simplified method created in response to the pandemic.
  • If you’re self-employed: Anyone who is self-employed and uses their home as their place of business has always been allowed to deduct home office expenses, as a portion of their home maintenance expenses. This deduction is not new for 2022.
  • If you have staff who worked from home: Your staff can also choose to use either the simplified or the detailed method.

If you’re an employee

If you work at a community health clinic or a health service organization, in academia or a ministry of health, as a hospitalist, or are otherwise considered an employee, and you have been required or have had the choice to work from home, you may be able to deduct employment expenses from your taxable income.

Historically, you would have needed a Form T2200, completed and signed by your employer. For 2022, because of the number of Canadians who continue to work from home due to the pandemic, the Canada Revenue Agency (CRA) extended the simplified rules for deducting home office expenses, offering a flat-rate deduction.

Flat-rate method

This temporary simplified method does not require a Form T2200 from your employer. An employee who worked from home more than 50% of the time over at least four consecutive weeks can deduct $2 for each day worked from home (not limited to the four-week period), up to a maximum of $500. You do not need to provide receipts for expenses incurred.

Detailed method

To make a claim based on the actual home office expenses you paid, you will still need a signed Form T2200 — or T2200S, a simplified version created for the pandemic.

On the T2200 or T2200S, your employer validates the terms of your employment, confirming, among other things, that you use a portion of your home for work. Generally, this means that you need to have used your home office space more than 50% of the time for at least four consecutive weeks in 2022.

You will need your employer to provide you with a copy of the T2200 or T2200s.

You will then  be able to claim employment expenses on your tax return using either Form T777 (Statement of Employment Expenses) or T777S, the simplified pandemic-specific version.

Calculation of work-space-in-the-home expenses:

Expenses you can claim include a portion of your:

  • electricity, heat and water bills, or the utilities portion of your condo fees
  • office supplies (not equipment)
  • rent
  • home internet service
  • maintenance expenses, but only if they were solely for your workspace. For example, if you painted your entire house, you can’t deduct any of that. But if you just painted your workspace, you can deduct all or most of that. Other eligible expenses include making minor repairs, purchasing household cleaning supplies and light bulbs

Note that as an employee, you can deduct rent, but you cannot deduct mortgage interest, property tax, insurance or any capital costs (i.e., equipment).

A common way to determine the pro-rated portion of your expenses is to estimate the area of your workspace as a percentage of the total finished area of your home.

Say you’re renting a 1,000-square-foot condo and your home office takes up 150 square feet, or 15%. Your annual expenses for utilities, internet, rent, and so forth are $30,000. Since your home office is 15% of the total space, you can deduct 15% of the expenses — or $4,500 — from your employment income. Depending on your tax bracket, this could save you up to 50% of that amount — or $2,250 — in taxes.

15% of expenses


If you don’t have a dedicated workspace — if, for example, you work on your dining room table —you can only deduct expenses for the time the room was used as a home office. If you only use the dining room table for work 50% of the time, you can only deduct 50% of the expenses for the space.

If you’re self-employed (but unincorporated)

If you’re self-employed, you can deduct business-use-of-home expenses to the extent that they’ve been incurred to earn business income.

Use Form T2125 (Statement of Business or Professional Activities) to report all revenues and expenses related to your professional activities. You can deduct a portion of the following under business-use-of-home expenses:

  • heat, electricity
  • insurance
  • maintenance
  • mortgage interest
  • property tax
  • other expenses (you need to specify)

To calculate how much to deduct, add up all your home office expenses and pro-rate them. A reasonable method is to figure out the proportion of the total finished square footage of your home that you use for business and use that same proportion of your total home office expenses.

If you use part of your home for both your business and personal living, calculate how many hours in the day you use the rooms for your business, and then divide that amount by 24 hours to determine the portion related to the household.

Note that unlike an employee, you can deduct the business portion of your mortgage interest, property tax and insurance.

If you’re incorporated

If you’re incorporated, you can do one of two things:

  1. The corporation can pay you rent for using your space, and the corporation deducts the rent as part of its overhead expenses. If you are personally charging rent to the company, this would be taxable income to you personally. However, you would then be able to deduct rental expenses to offset the rental income.
  2. If you pay yourself a salary, you can deduct your home office expenses as an employee on your personal tax return using Form T777 (Statement of Employment Expenses) or T777S (the simplified pandemic version) if you meet the eligibility requirements.

It is probably better to charge rent to the corporation since the business itself could deduct more expenses (e.g., property taxes, insurance, etc.). There are also fewer restrictions on eligibility compared with deducting home office expenses as an employee.

 If you have staff who worked remotely: 

If you have employees who worked from home they can choose to use either the simplified or the detailed method. You’ll need to provide each employee who chooses the detailed method with a Form T2200 or T2200S so they can deduct their employment expenses.

Keep track of your expenses

Please note that the flat rate method for employees is a temporary measure that has been extended for 2023. Be sure to keep track of any expenses that you incur while working remotely this year in case the CRA wants to see them.

Your accountant can help you claim these expenses. If you have any questions about financial planning, contact your MD Advisor*.
