感谢baibaitu的回答。我刚才又仔细阅读和填写了schedule 6,像路过繁华家里的情况,一方是全年居民,另一方不是的,就只能当作没有eligible spouse的情形填了,“If you were married or living in a common-law relationship but did not have an eligible spouse or an eligible dependant, complete this schedule using the instructions as if you had neither an eligible spouse nor an eligible dependant.” 那么填这个schedule 6的时候,配偶的收入就不用填,只填一人的收入,如果adjusted net income超过$17,478,就领不到WITB了,如果路过繁华一人的收入介于$3000和$17,478之间,还是会有WITB的。
