If you are a US resident for tax purposes, you can file jointly with your nonresident spouse. However, without your spouse's SSN or ITIN, you would not be able to e-file. You basically are going to file your 2018 taxes and apply for the ITIN together. Here is how you do it:
- In the program, leave the SSN space blank
- After completing the return, print out the forms. Write APPLIED in the spouse's SSN space.
- As TurboTax does not support the Form W-7, fill out the forms by following W-7 and attach other required documentation
- Submit all forms and documents to the IRS Austin location in Texas. (see Form W-7 instructions)
