Both the 1040NR and 1040NR-EZ forms ask for a social security number or an ITIN. Can I file a tax return if I don’t have a tax ID?
No. A U.S. tax identification number is needed in order for you to file a tax return. All F-1 and J-1 visa holders and J-2 dependents who are employed in the U.S. should have a social security number. If you are not eligible for a social security number, you must obtain an Individual Taxpayer Identification Number (ITIN) from the IRS. To apply for an ITIN it is necessary to complete a Form W-7.
