---學校發工資時總是先把聯邦稅，州稅和市稅都先扣去了。因為扣得還略多一些，
---我每次報稅總能拿回一些。
you need to keed receipts for all deduction item.

you should file tax annually. If you filed for every 3 yrs. you will need to pay original tax, interest, plus some putative money
----我不知道是我出了問題還是IRS出了問題。
not sure if you filed yourself or some professional. if hire professional (I means with licence) for you, and you tell them all truth. Then the professional will take full responsibility
