If you are working from home, you may be able to deduct some expenses relating to your home. Your Work-Space-In Home is where you primarily do your work, meaning greater than 50% of the time. This space should be used to earn employment income on a regular and continuous basis for meeting clients or customers.
If you meet the criteria, then you may be able to deduct a percentage of your expenses, including electricity, heating, maintenance, and cable/internet. If you are a commissioned employee, you may also be able to deduct home insurance and property tax.
What you cannot deduct is mortgage interest and depreciation (or CCA) on your home. Also, you cannot deduct food and veterinary bills for your dog, even if he/she is considered to be part of your security system.
To be able to claim the work-in-space-home deduction, you will need to ask your employer for a completed and signed T2200 – Declarations of Conditions of Employment.
