报税的时候，参考了微微在美国写的 “美国报税的简单介绍和报税的几种方式”

应该先报美国的税，包括联邦税和州税（如果你所在的州要交税的话）。用雇主给你的W-2。你应该有SSN或ITIN号码吧？美国报税的截止日期是4月15日。你也许可以把已经扣除的税拿回来一部分或全部。

然后你再报加拿大的税。你需要用到T2209和T2036，这样你可以把在美国交的各种税的总合折算成Foreign Tax Credit（参照你的W-2），用来减少加拿大的税率。

T2209 - Federal Foreign Tax Credits
T2036 - Provincial or Territorial Foreign Tax Credit
