ITIN Support for US Tax Filing
An Individual Taxpayer Identification Number (ITIN) is required by non-US persons — including foreign spouses of US citizens and non-resident alien LLC owners — who need to file US tax returns or be included on a joint return. Obtaining an ITIN requires filing Form W-7 with original identity documents or certified copies, and must be coordinated carefully with the tax return. We handle ITIN applications alongside your filing.

Frequently asked questions about ITIN Support for US Tax Filing
What is an ITIN and who needs one?
An Individual Taxpayer Identification Number is a 9-digit number issued by the IRS to individuals who need to file US taxes but aren't eligible for a Social Security Number. It's required for non-US persons included on a joint return, non-resident LLC owners, and others with US filing obligations but no SSN.
Can I file my tax return before I have an ITIN?
You can file your return with the ITIN application simultaneously. The return is typically held while the ITIN application is processed, then processed once the ITIN is issued. Alternatively, you can file an extension while awaiting the ITIN.
How long does it take to get an ITIN?
Typically 7–11 weeks when mailing the application to the IRS directly. Using a Certifying Acceptance Agent (CAA) like Nomadic.Tax can allow certified copies of documents to be submitted, avoiding the need to mail original passports.
