那就用turbotax把税表打出来,填好W7表,寄出?可不可以efile,然后分开寄出w7? 多谢 答案; Because you are filing your tax return as an attachment to your ITIN application, you should not mail your return to the address listed in the Form 1040, 1040A or 1040EZ instructions. Instead, send your return, Form W-7 and proof of identity documents to: Internal Revenue Service Austin Service Center ITIN Operation P.O. Box 149342 Austin, TX 78714-9342
