最近老搬家，有封信就miss了。刚注意到，是工作过的公司发给我的，关于退税的，说关于EITC（federal earned income tax credit）信是这么说的：

based on your annual earnings, you may be eligible to receive the earned income tax credit from the federal government. The earned imcome tax credit is a refundable federal imcome tax credit for low-income working incividuals and family. The earned income tax credit has no effect on certain welfare benefits. ............................Even if you do not owe federal taxes, you must file a tax return to receive the earned imcome tax credit. Be sure to fill out the earned imcome tax redit form in the federal imcome tax return booklet.

然后让我去IRS网站看IRS notice 797 或者W-5表格。。

我去看了，但是还是不明白是什么意思，急着上来问问jms，这是个什么东东，我似乎没填过W5表格，这个是不是会退给我钱呢？？？
