I want to file jointly with my spouse who lives in Chile. He doesn't have an ITIN/or SSN.
(a few subquestions being asked):
1)When I file my taxes jointly and send them off, I also have to attach a separate page to the W-7 which includes their compensation they've made while working in Chile correct? Is there a particular format they have to use to document this? Or what is the format in which they have to present this as? Also,. since they have't been given a ITIN number yet (the request form is obviosly attached) do we just leave that section blank then?
2) Since they are obviosly not in the country, can I fill out and sign the W-7 on their behalf?
3) If I choose to get an extension to do this, how will my employer know how much money to take out of my paychecks since I am being given a 6 month extension to tell them? Will they take the money out as if I filed single, and then I will be re-imbursed in the future once we have officially filed jointly?
