07年在国内有存款，请问是否要申报

本人06年12月拿绿卡，07年在国内有存款，08年存款全部汇到美国买房子，当时没有申报个概念，现在看新闻，税局要在8月前申报加罚款，不知道如何是好！

没必要吧，你现在要报的是2010年的税，也就是说2010年你的帐号所赚的利息。

you may need to file 1040X for all the years you receive interest payments before you closed the account.  I think you can get some foreign tax creadit back for the taxes you paid in China on those interests.  so your back tax may not be a lot, especially you didn't make much at the time).  I think you should consult an accountant to make it right.
