An ITIN — Individual Taxpayer Identification Number — is a nine-digit tax processing number the IRS issues to people who need a US tax ID but aren’t eligible for a Social Security Number: non-resident freelancers with US clients, foreign LLC owners, spouses of US residents. It starts with the digit 9 (9XX-XX-XXXX) and lets you file a federal tax return, report US-source income, claim treaty benefits, and — depending on the institution — open US bank accounts.
This guide walks through exactly how to get an ITIN in 2026: who qualifies, the ITIN vs EIN vs SSN distinction, the Form W-7, required documents, realistic processing times, and renewal rules.
Disclaimer: This is general information, not tax advice. ITIN rules change, and your situation may have wrinkles this article can’t see. Confirm everything with the IRS or a qualified tax professional before you file.
What an ITIN is (and isn’t)
An ITIN is a nine-digit tax processing number issued by the IRS, always starting with the digit 9 (formats like 9XX-XX-XXXX). It exists for one purpose: to let people who aren’t eligible for an SSN comply with US tax law. You can use it to file a federal tax return, report US-source income, claim treaty benefits, and — depending on the institution — open US bank accounts or form an LLC.
What it is not: an ITIN doesn’t authorize work in the US, doesn’t unlock Social Security benefits, and isn’t valid ID for immigration. It’s a tax number, full stop.
Who needs an ITIN
You’re eligible for an ITIN if you have a US federal tax filing or reporting obligation and you aren’t eligible for an SSN. Form W-7 lists six application categories on line 6d:- Non-resident aliens filing a US tax return — freelancers and contractors with US clients, landlords with US rental income.
– US resident aliens (for tax purposes) filing a US return.
– Spouses or dependents of US citizens or residents, or of non-resident aliens holding a US visa.
– Non-resident aliens claiming a tax treaty benefit — if your country’s treaty with the US reduces your withholding.
– Foreign nationals with US-source income subject to withholding.
– Non-resident members of a US partnership, or foreign owners of a US LLC.
If you already have (or can get) an SSN, the IRS will reject your ITIN application. And if you’re forming a US entity rather than identifying yourself as a person, what you want is an EIN — here’s how to get one without an SSN.
ITIN vs EIN vs SSN: which one do you actually need?
People mix these three up constantly, so here’s the clean distinction:
| Number | For | Issued to |
|---|---|---|
| SSN | Employment, Social Security, taxes | US citizens and authorized workers only |
| ITIN | Tax filing/reporting for people ineligible for an SSN | Individuals (not entities) |
| EIN | Tax ID for businesses — hiring, business bank accounts, business tax returns | Business entities (LLC, corporation, partnership) |
Rule of thumb: if you need to file a personal return or get paid as an individual, it’s an ITIN. If your company needs an ID for the bank or the IRS, it’s an EIN. Foreign LLC owners often end up needing both — an EIN for the company and an ITIN for themselves.
The Form W-7 application, step by step
Form W-7 is a two-page form. It’s not complicated, but small errors cause most rejections and delays:1. Pick your reason (top of form). Check exactly one box (a–h). If multiple seem to fit, choose the most specific. Renewals also check the “Renew an existing ITIN” box.
2. Name (lines 1a/1b). Exactly as it appears on your identity documents; include your name at birth on 1b if it differs.
3. Address (lines 2–3). Line 2 is where the IRS sends correspondence and your ITIN letter. Line 3 is your foreign address; leave blank if your mailing address is already your foreign address.
4. Birth and identity (lines 4–5). Date of birth (MM/DD/YYYY) plus city and country of birth.
5. Identifying information (line 6). Where errors happen most: citizenship (6a), optional foreign tax ID (6b), visa details if applicable (6c), the document you’re submitting (6d — type, issuing country, ID number, expiration), US entry date for nonresidents (6e).
6. Sign and date. An unsigned W-7 goes straight into the rejection pile.

Which documents you need
The IRS accepts 13 types of identity and foreign status documents. The good news: a valid passport is the single document that proves both identity and foreign status — if you have one, that’s all you need. Without a passport, you’ll need at least two documents from the IRS list, such as a national ID card plus a birth certificate. A US driver’s license proves identity only — it can’t prove foreign status.
All documents must be originals or certified copies from the issuing agency — not photocopies. That’s the catch with the mail route: you’d be sending your actual passport to Austin, Texas.
The three ways to apply
1. By mail (free, but you mail your passport)
Mail the completed W-7, your tax return, and your original passport (or certified copy) to the IRS ITIN Operation in Austin, Texas:
Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342
It’s free. The IRS normally returns documents by mail within about 60 days.
2. Through a Certifying Acceptance Agent (free passport)
A Certifying Acceptance Agent (CAA) is a tax professional authorized by the IRS to verify your passport in person and submit a certificate of accuracy instead of the original. You keep your passport. Agents charge a fee — commonly $100 to $300 — on top of preparing any tax return. The IRS publishes a directory of acceptance agents by state.
3. In person at an IRS Taxpayer Assistance Center (free)
Some IRS offices verify passports in person by appointment — free, and you keep your passport. Appointments can take weeks to get, and only about a dozen TAC locations process ITINs. Call 1-844-545-5640 to schedule.
Beware “express ITIN” ads
Nobody can speed up the IRS. Anyone promising you an ITIN in days, or asking you to pay the IRS a fee, isn’t legitimate. The IRS charges $0 for W-7 processing — full stop.
How long ITIN processing takes in 2026
The IRS processes ITIN applications in roughly 6 to 11 weeks from the date it receives your W-7:
- Off-peak (May–December): typically 6 to 8 weeks.
- Peak tax season (mid-January through April): 9 to 11+ weeks.
- Applying from abroad: expect the longer end of the range.
The application method doesn’t change IRS processing time — everything goes through the same queue — but a complete, error-free application avoids correction notices that add 4 to 8 weeks.
When approved, you’ll receive a CP565 notice by mail with your new ITIN. If rejected, you’ll get a CP566 explaining why.
How to check your ITIN application status
Call the IRS ITIN helpline at 1-800-908-9982 (US) or 1-267-941-1000 (international). Have your name, mailing address, and date of birth ready. If 11 weeks pass with no response, call — don’t just keep waiting.
Renewal rules: the part most people miss
ITINs don’t last forever. Under the PATH Act of 2015:
- An ITIN expires if you don’t use it on a federal tax return at least once in three consecutive tax years. Skip three years of filing, and it’s dead.
- ITINs with middle digits 70 through 88 issued before 2013 already expired under the IRS’s rolling expiration schedule.
To renew, file a new Form W-7 with the renewal box checked. Unlike a new application, a renewal doesn’t require a tax return. Processing runs about 6 to 11 weeks. And no — there’s still no online option. W-7 is paper only: mail, CAA, or TAC.
Common mistakes that delay or kill applications
- Wrong reason code. Checking the wrong box on line 6d is one of the top rejection causes.
- Unsigned form. Always sign and date — an unsigned W-7 goes straight into the rejection pile.
- Photocopies instead of originals/certified copies. The IRS sends them back with a rejection.
- Applying when you qualify for an SSN. Automatic rejection.
- New applications generally must be attached to a federal tax return unless you qualify for an exception.
- Mailing to the wrong address. The ITIN Operation in Austin is not the regular 1040 address.
ITIN and banking
One of the most common reasons freelancers and founders apply for an ITIN is banking access — some US banks accept an ITIN where they’d otherwise require an SSN.

Frequently Asked Questions
Is it free to get an ITIN?
The IRS charges $0 to process Form W-7. Your only costs are postage (mail route) or a professional’s fee — typically $100 to $300 — if you use a Certifying Acceptance Agent. Anyone charging an “IRS fee” for an ITIN is not legitimate.
Can I apply for an ITIN online?
No. As of 2026 there’s no online ITIN application or renewal. You must file a paper Form W-7: by mail to Austin, Texas; through a Certifying Acceptance Agent; or in person at an IRS Taxpayer Assistance Center.
How long does it take to get an ITIN in 2026?
Roughly 6 to 11 weeks: 6 to 8 weeks off-peak (May–December), 9 to 11+ weeks during tax season (mid-January through April) or when applying from abroad. Correction notices for incomplete applications add 4 to 8 weeks, so file it right the first time.
What’s the difference between an ITIN and an EIN?
An ITIN is for individuals who can’t get an SSN — it goes on personal tax returns. An EIN is for business entities — LLCs, corporations, partnerships — for business tax filings, hiring, and business bank accounts. Foreign LLC owners often need both.
Does an ITIN expire?
Yes. An ITIN expires if it’s not used on a federal tax return at least once in three consecutive tax years. ITINs with middle digits 70–88 issued before 2013 also expired under the IRS rolling schedule. Renew with Form W-7 (renewal box checked) — no tax return required for renewals.### Can I open a US bank account with just an ITIN?
Some banks accept an ITIN in place of an SSN for personal accounts, and several fintech/virtual banks work with foreign founders — policies vary by institution, so confirm with the bank directly. See our guide to virtual banks for LLCs without SSN/ITIN for options.
