I am a permanent resident and married with non-resident wife (F1 student, not eligible to apply SSN) in 2017. I think we need to apply ITIN along with my tax application (married joint) and i think we need to attach her passport for this application. But she changed last name to my last name through our marriage, but her passport name has not been changed yet, and this name changing process will take long time and could miss mid April. What is the best way for this situation?
Should I submit tax return and apply ITIN with her maiden name? or do we need to have an updated passport then apply for ITIN for this tax return process?
First, you need to apply for an extension to file your tax return. When the extension is approved, understand that does NOT extend your deadline to pay any 2017 tax liability that may be due. It only extends your time to file the return until Oct, 2018.
Next, get the passport updated, then apply for the ITIN. With the tax filing extension, you should have plenty of time if you don't waste the time and get on this now.
