Ah yes, Canada. I'm also in Ontario (near Ottawa). I'm not a tax expert but this is based on my own experience with microstock income for about 5 years.

I'm not aware of any income limitations for home office. I certainly use that deduction (I have a small home studio as well). As has been mentioned already, you're not an employee but are getting paid royalties. Since you are in Canada, you're probably receiving a T5 from IS. I've reported here in the past limitations in the tax software (Turbotax and Quicktax before it) related to t5 royalties. The software adds the income to your regular salary by default. If this is your issue, send me a site mail and I'll describe what I do to fix the problem.

Regards,

John
