All my income is T5 dividend income from my incorporated company. When they ask me "did you work in 2014" do I say no? I have no T4 income

If you have a T5 to enter, in the Profile section, answer Yes to the question: did you have income from investments such as interest earned on investments, the sale of stocks or stock options, the sale of real property, income from rental property or other related investment expenses?

Then, select the T5 checkbox.
