I am an over-the-phone interpreter and my employment requires me to work from home. I was issued with a T4 for employment income but since I work from home, i want to claim part of my home expenses. Should I claim my home expenses on T2125E Statement of Business or Professional Activities? In my case, do I report $0 income on T2125 form since I report it under Employment Income already?
No. These home office expenses are employment expenses since you are employed, not self-employed. To claim employment expenses, you are required to have a completed/signed Form T2200 from your employer stating that your home office is a requirement for your job.
