Have a Tax Question? Ask a Tax Expert
Hi, my name is Mark. I would be happy to help you with your questions. You would need to apply for an ITIN number for your wife. You could put "Applied For" as her number but this would likely create more trouble in the processing of the return.
Ok I did not realize that your Wife had a Social security number. You would use her Social Security number on the 1040X. Even though the number was issues in 2016. The Social Security number would be used to keep track of her tax information.
