Quick answer

The $2 per day flat rate method is gone; it only applied to 2020 through 2022. For 2023 and later, employees claim home office costs using the detailed method with a Form T2200 signed by their employer, deducting the workspace percentage of eligible costs. Self-employed people use the business-use-of-home rules, which allow a wider range of costs including mortgage interest.

Are home office expenses tax deductible in Canada?

Yes, but how you claim depends on whether you are an employee or self-employed, and the temporary pandemic shortcut no longer exists. Employees must use the detailed method and hold a Form T2200 signed by their employer confirming they were required to work from home. The deduction is the workspace percentage of eligible costs.

What counts as eligible differs by status. Salaried employees can claim a share of utilities, maintenance, and rent, but not mortgage interest, property tax, home insurance, or capital cost allowance. Commission employees can add property tax and home insurance. Self-employed people, under the business-use-of-home rules, can claim the widest range, including mortgage interest. See the wider Canadian expense rules for context.

How much can you claim?

Your claim is the workspace percentage of eligible costs. The percentage is your work space area divided by the total finished area of the home, adjusted for hours of use if it is a common area.

Capital cost allowanceNoYes (optional)

Worked example. An employee uses a 10 square metre room in a 100 square metre home, a 10% workspace. With $4,000 of utilities and $18,000 of rent for the year, she claims 10%, which is $2,200. She cannot add mortgage interest or property tax. A self-employed person in the same home could also claim 10% of mortgage interest and property tax, but only up to the point of not creating a loss, with the rest carried forward.

Record-keeping requirements

Keep your utility, rent, and maintenance bills, your workspace and total-area measurements, and, for employees, the signed Form T2200. The self-employed keep mortgage, property tax, and insurance statements as well. Records must be kept for six years. GST/HST registrants keep the documentation needed to claim input tax credits on the business portion.

How to claim, step by step

  1. Employees: get a Form T2200 signed by your employer for the year.
  2. Measure your work space area and the total finished area of your home.
  3. Work out your workspace percentage, adjusting for hours if it is a common area.
  4. Apply that percentage to your eligible costs for your status.
  5. Self-employed: remember the deduction cannot create a loss, but the excess carries forward.
  6. Keep all bills, measurements, and the T2200 for six years.

Common mistakes

  • Using the $2 per day flat rate, which no longer exists after 2022.
  • Claiming home office expenses as an employee without a signed T2200.
  • A salaried employee claiming mortgage interest or property tax, which are not allowed.
  • Self-employed filers using the deduction to create a business loss instead of carrying it forward.
  • Overstating the workspace percentage or forgetting the hours adjustment for a common area.

Software that helps

A home office claim is only as good as the bills and measurements behind the percentage.

  • QuickBooks tracks home office costs against the business for self-employed filers.
  • ExpenseFlow captures your utility, internet, and maintenance bills, codes each with the correct GST/HST treatment, and syncs them to Xero or QuickBooks, so the records behind a home office claim sit in one place.
  • Wealthsimple Tax walks employees through the detailed method at filing time.

Questions, answered

Common questions

Is the temporary flat rate method still available in Canada?

No. The $2 per day temporary flat rate method applied only to the 2020, 2021, and 2022 tax years. For 2023 and later, employees must use the detailed method and have a Form T2200, Declaration of Conditions of Employment, signed by their employer.

What is Form T2200 and do I need it?

Form T2200 is a declaration your employer signs confirming you were required to work from home and to pay for your own workspace costs. Employees claiming home office expenses for 2023 onward need a signed T2200. You keep it on file rather than filing it with your return.

How do I calculate my workspace percentage?

Divide the area of your work space by the total finished area of your home. If you use a common area such as a dining table, you also adjust for the hours per week it is used for work, so the claim reflects both the space and the time it is used for employment.

Can an employee claim mortgage interest or property tax?

Salaried employees cannot claim mortgage interest, property tax, home insurance, or capital cost allowance. They can claim a share of utilities, maintenance, and rent. Commission employees can additionally claim property tax and home insurance, but still not mortgage interest.

What can self-employed people claim for a home office?

Self-employed people use the business-use-of-home rules and can claim a share of utilities, maintenance, rent, property tax, home insurance, and mortgage interest. The deduction cannot create or increase a business loss, but any unused amount carries forward to a future year.
