Can You File US Taxes Without a Social Security Number?

Can I file US taxes without an SSN?

Yes. Anyone required or choosing to file a US federal tax return can do so using an Individual Taxpayer Identification Number (ITIN) instead of a Social Security number.

Immigration status has no bearing on whether you can file; the tax system and immigration enforcement are, by design, separate systems. Not sure which number applies to you? Our ITIN vs SSN guide breaks down the difference.

Why people file taxes without SSN

There are two practical reasons people without a Social Security number choose to file US taxes:

• Getting money back. If taxes were withheld from your pay, which happens even if you’re paid with an ITIN or under someone else’s number, filing is the only way to get that money refunded to you.

• Building a documented history. Some immigration attorneys have pointed to consistent tax filing as one factor that can matter in certain future immigration proceedings. This is not a guarantee of any outcome, and whether it’s relevant depends entirely on individual circumstances.

How to file taxes without an SSN

Filing without an SSN mostly comes down to one extra step: applying for your ITIN at the same time you file your taxes for the first time.

1. Fill out Form W-7

This is the IRS’s application for an ITIN. You’ll attach it directly to your federal tax return. You don’t need to file it separately or in advance.

We cover the ITIN application process in our How to Get an ITIN Number: Step by Step guide.

2. Gather your ID documents

A valid passport is usually enough on its own, since it proves both your identity and your foreign status. Without one, you’ll need to submit two documents instead (like a national ID card plus a birth certificate).

3. Choose how to submit everything

You’ve got three options:

• Mail it in. Send your W-7, tax return, and original ID documents (or certified copies from the issuing agency) to the IRS’s ITIN Operations address. The downside: your original documents are out of your hands for weeks.

• Use a Certified Acceptance Agent (CAA). A CAA can verify your documents in person and forward copies to the IRS, so you’re not mailing your passport anywhere. Many tax preparers and community organizations offer this.

• Visit an IRS Taxpayer Assistance Center. Some TACs handle ITIN document verification by appointment, which lets you keep your originals.

4. Wait for processing

Once submitted, expect 7 to 11 weeks most of the year, or longer (up to 16 weeks) during tax season or if you’re applying from abroad.

5. File with your ITIN going forward

Once it’s issued, that number is yours to use on every future return. There’s no need to reapply each year, as long as you use it at least once every three years.
