To file your taxes without your wife's Social Security Number (SSN), follow these steps:
- File by Mail: You cannot e-file without your spouse's SSN. You will need to file a paper return by mail.
- Include a Cover Letter: Attach a cover letter to your tax return explaining why your spouse's SSN is missing.
TurboTax Instructions
- Prepare Your Return: Complete your tax return in TurboTax as usual.
- Print Your Return: Ignore any SSN error messages and print your return.
