Tax return cannot be submitted and filed through TurboTax without either an ITIN or SSN. To apply for an ITIN, you will need to submit a Form W-7, Application for IRS Individual Taxpayer Identification Number. Please follow this link to the IRS website to obtain a form.

Once you have received your ITIN, you can come back and complete your tax return in TurboTax.
