These forms can be tough to navigate as an employee. Helping them understand their T2200 or T2200S eligibility (and ensuring they're aware their forms may not be accepted by CRA) is one way you can help them get through their own tax process confidently.

T2200 Form

A T2200 form can be shared with employees as a PDF that can be printed and completed manually, or as a fillable/saveable PDF, which can be completed electronically.
Here’s the link to both versions.

Note: If an employee was already working from home, and wants to claim their 2020 work-from-home expenses (that aren’t a result of working from home due to the COVID-19 pandemic), they still need to complete the T2200 form.

T2200S Form (New for 2020)

If an employee worked from home in 2020 as a result of the COVID-19 pandemic, and they wish to claim their work-from-homes expenses in excess of the $400 maximum available through the temporary flat method, they’re required to obtain a T2200S form from their employer to confirm they were required to work from home.

In Québec

For employees in Québec, the T2200 equivalent form is called TP-64.3-V, General Employment Conditions. It is also available in PDF and fillable PDF formats.
Here's the link to both versions.
