No, you cannot claim mortgage interest or property taxes on your home office as a deduction on your Canadian tax return, even if you use a dedicated room for work. The CRA treats your home as a personal residence, not a business asset. Mortgage interest and property taxes are considered personal expenses tied to your primary dwelling and are not tax deductible under any home office claim method. However, other home office expenses like utilities, rent (if you rent your home), and maintenance costs may be deductible depending on how you calculate your claim. The CRA maintains strict boundaries between personal housing costs and business expenses. Here's why these two major costs fall on the personal side: Mortgage interest: Your mortgage is a debt obligation on your principal residence. Even though part of your home is used for work, the mortgage secures the entire property, not just your office space. Personal use of your home (sleeping, cooking, entertaining family) means the CRA does not allow you to deduct any portion of mortgage interest. Property taxes: These are levied on the entire property by your municipality.
No. The CRA does not allow any deduction for mortgage interest on your principal residence, regardless of home office use. Your entire mortgage is considered a personal expense tied to your primary dwelling.
No. Property taxes are levied on the entire property and are classified as personal, non-deductible expenses. You cannot claim a percentage of them based on your office space, even under the detailed expense method.
Yes, a proportional amount of your home insurance premium can be claimed under the detailed expense method. Calculate your home office's percentage of total square footage and apply it to your annual insurance cost.
It depends on your situation. The simplified method is easier and requires no receipts, but if your actual home office expenses exceed $2 per square foot, the detailed method will give you a larger deduction. Compare both calculations to see which works better for you.
Yes. Self-employed individuals can claim home office expenses more easily, while salaried employees need written employer confirmation that they work from home by employer direction and pay unreimbursed expenses themselves.
