凡是中文报道，几乎都有错误。（怎么融入本地社会？ 🤭）
事实上，如果你只申请那$400，是既不需要T2200S, 更不需要 T2200，当然也无需雇主签字。
这个中文报道给出的CRA链接是这样写的：
You do not have to（你不需要做以下事情）: calculate the size of your work space, keep supporting documents or get Form T2200 completed and signed by your employer.
在什么情况才需要它们？是当你想提供细节获得更多时
T2200S：
For employees who worked from home in 2020 due to COVID-19 and wish to use the detailed method to deduct home office expenses (work space in the home and supplies).
T2200：
For employees who worked from home in 2020 due to COVID-19 and wish to deduct home office expenses (work space in the home and supplies) and also wish to claim other employment deductions; as well as for employees who are normally required to work from home.
