As IRS does not allow e-filing without a SSN or ITIN on the tax return, you will have to submit your tax return by mail.
-In the program, as you enter the information, leave the SSN space blank
-After you complete entering all the required information, print out returns and required forms. Enter “NRA” in the space for Spouse's identifying number. ( NRA stands for Nonresident Alien) Do not leave the space blank.
-Submit all the forms and required documents to IRS based on the instructions on your print-out.
