Everything about claiming home office expenses on your tax return

The flat rate method (temporary — check CRA for current availability) allows you to claim $2 per day for each day you worked from home, up to a maximum of $500 (250 days). You do not need to track detailed expenses or calculate workspace percentage. No receipts are needed, and you do not need a signed Form T2200 from your employer.
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.
The flat rate method was originally introduced as a temporary measure during COVID-19. CRA has extended it for some years. Check the CRA website for the latest information on whether it is available for the 2025 tax year. If it is not available, you will need to use the detailed method with Form T2200.
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.
The maximum deduction is $500, which is $2 per day for a maximum of 250 working days. You can claim any number of days up to 250. Even if you worked from home for more than 250 days, the deduction is capped at $500. No supporting documentation is required beyond recording the number of days.

CRA-Aligned: Calculations use the CRA flat rate of $2/day (max $500) for the 2025 tax year. The detailed method requires supporting documentation. Consult a tax professional for personalised advice.
