Is there any further actions I need to take other than clicking Yes on the T4 form for the $400 working from home deduction?

You would also need to go to the Employment Expenses to answer some questions regarding eligibility and how many days you worked from home.

FYI: The $400 is the maximum amount of the deduction that you can get, but you may get less depending on how many days you worked from home. It’s $2 per day, up to $400 if you worked 200 or more days from home.
