Everything about claiming home office expenses on your tax return

The temporary flat rate method let you claim $2 per day for each day you worked from home, up to a maximum of $500 (250 days). It applied to the 2020, 2021 and 2022 tax years only — it cannot be claimed for 2023 or later years, including 2026. It is shown here for comparison; for a 2026 claim you must use the detailed method.
Form T2200 (Declaration of Conditions of Employment) is a form your employer must sign to certify that you were required to work from home and pay your own expenses. It is required for the detailed method but not for the flat rate method. Self-employed individuals do not need a T2200 — they claim home office expenses directly on Form T2125.
Eligible expenses include rent (not mortgage principal), utilities (electricity, heat, water), home insurance, maintenance and minor repairs, internet (work portion), and property taxes. Mortgage interest is not deductible for employees but may be for self-employed individuals. You claim a proportional amount based on the workspace size relative to your entire home.
Divide the area of your dedicated workspace by the total area of your home. For example, if your office is 200 sq ft and your home is 1,000 sq ft, the percentage is 20%. If your workspace is used for both work and personal purposes, you may need to prorate further based on hours used for work.
Yes, commission employees can claim additional expenses beyond what salaried employees can, including property taxes and home insurance premiums. They must have a signed Form T2200 from their employer confirming they are required to pay their own expenses and work from home.
No. The flat rate method was a temporary measure during COVID-19 and applied to the 2020-2022 tax years only. For 2023 and later years, including 2026, you must use the detailed method, supported by Form T2200 from your employer (or Form T2125 if self-employed).
Yes, self-employed individuals can claim home office expenses on Form T2125 (Statement of Business or Professional Activities). They can claim a wider range of expenses including mortgage interest (but not principal), property taxes, home insurance, utilities, maintenance, and internet. The workspace must be the principal place of business or used exclusively for earning income.
Under the temporary flat rate method (2020-2022 tax years only), the maximum deduction was $500 — $2 per day for up to 250 working days. Even if you worked from home for more than 250 days, the deduction was capped at $500. No supporting documentation was required beyond recording the number of days.

CRA-Aligned: For the 2026 tax year only the detailed method can be claimed; it requires supporting documentation. The $2/day flat rate (max $500) applied to the 2020-2022 tax years only. Consult a tax professional for personalised advice.
