ITIN for Amazon FBA Sellers: Complete 2025–2026 Guide
Non-resident Amazon FBA sellers need an ITIN to file U.S. taxes, claim treaty benefits, and stop the 30% default withholding. This guide covers when you need one and how to get it without mailing your
Plenty of non-U.S. sellers set up their Amazon account, get an EIN for their LLC, and assume they're done with U.S. tax IDs. Then the first payout arrives — and Amazon has withheld 30%.
That's the moment most international sellers discover they need an ITIN.
This guide explains the exact situations where an ITIN is required, where an EIN alone is sufficient, and the fastest way to get sorted without disrupting your business.
The EIN/ITIN confusion that costs sellers money
Amazon sellers commonly confuse two different U.S. tax IDs:
EIN (Employer Identification Number) — identifies your business. Your LLC needs one. You can get it as a non-resident by filing Form SS-4 by fax, and it's available to any foreign-owned business without an SSN or ITIN.
ITIN (Individual Taxpayer Identification Number) — identifies you personally for U.S. tax purposes. Required when you — as an individual — have a U.S. tax filing obligation.
Your LLC needs the EIN. You personally may need the ITIN. They're not interchangeable.
When you actually need an ITIN as an Amazon seller
Situation 1: You file Form 1040-NR
If your U.S. LLC generates income effectively connected with a U.S. trade or business, you're required to file Form 1040-NR — the non-resident tax return. This form requires a personal TIN. Since non-residents can't get an SSN, the ITIN is the only option.
Situation 2: You want to claim a tax treaty benefit
The default withholding rate on U.S.-source income for non-residents is 30%. If your home country has a tax treaty with the U.S., you can claim a reduced rate — but only if you have an ITIN to put on Form W-8BEN. Without it, Amazon defaults to 30% regardless of any treaty.
Situation 3: Your account triggers a 1099-K
Starting with the 2024 tax year, the 1099-K reporting threshold dropped significantly. If your account generates a 1099-K and you need to respond to the IRS, an ITIN is required.
When you might be fine with just an EIN:
If your LLC sells on Amazon, has an EIN, and your only U.S. tax obligation is the business return (Form 5472 for foreign-owned single-member LLCs), and you're not filing a personal 1040-NR, you may not need an ITIN yet. The operative word is "yet" — most active sellers eventually reach a point where a personal return becomes necessary.
The 30% withholding problem, explained plainly
Here's what actually happens when you don't have an ITIN and no tax documentation on file with Amazon:
Amazon is required by law to withhold taxes on U.S.-source income payments to non-residents. Without proper tax forms from you, the default rate is 30%. That's not Amazon being difficult — it's the IRS requirement.
The way to stop it: submit Form W-8BEN to Amazon, with your ITIN included, claiming whatever treaty rate applies to your country. Amazon then adjusts the withholding rate going forward.
The taxes already withheld before you had an ITIN? You recover them by filing Form 1040-NR for that tax year — which, again, requires an ITIN. There's no other path to that refund.
What the ITIN application actually involves
You file Form W-7 with the IRS. In most cases, you attach your U.S. tax return (Form 1040-NR) to the W-7 — they're submitted together. The IRS reviews both, issues the ITIN, and processes the return.
Three submission methods exist:
- Mail your original passport to the IRS in Austin, TX — passport unavailable for 7–11 weeks, international mail unreliable
- Visit a U.S. IRS Taxpayer Assistance Center in person — only available inside the U.S.
- Use a Certified Acceptance Agent (CAA) — the CAA verifies your passport remotely, keeps the passport with you, handles the paperwork and mailing
For anyone outside the U.S., option 3 is the only practical choice.
Processing times right now (May 2026)
The IRS is processing Form W-7 applications within 11 weeks of receipt as of May 2026. During the 2025 federal shutdown (October–November 2025), timelines extended significantly — some applications sat for 4–5 months. That backlog has been worked through.
Outside tax season (May–December): typically 7 weeks. During tax season (January 15–April 30): 9–11 weeks.
Plan around this. If you're starting to sell and want your ITIN before your first full tax year closes, apply early.
ITIN vs. EIN: a plain-language summary for Amazon sellers
| What you need it for | Which number |
|---|---|
| Amazon seller account (business entity) | EIN |
| W-8BEN (treaty rate claim, personal) | ITIN |
| Form 1040-NR (personal tax return) | ITIN |
| Form 5472 (foreign-owned LLC annual filing) | EIN (for the LLC) + ITIN (for the owner's return, if applicable) |
Many sellers operating through a U.S. LLC need both: the EIN for the LLC's tax filings and bank account, and the ITIN for their personal 1040-NR.
The mistake we see most often
Sellers apply for an ITIN after their first full year of sales — after taxes have already been over-withheld, after penalties have started accruing for late 1040-NR filings. The ITIN application itself is straightforward; the problem is that most sellers don't realize they need one until something goes wrong.
If you're launching a U.S.-based Amazon business as a non-resident, apply for the ITIN at the same time you form the LLC and get the EIN. The applications are independent — you don't need one to apply for the other.
Frequently Asked Questions
Does Amazon require an ITIN to create a seller account? Not at account creation. But they will require tax documentation once your account reaches certain thresholds, and 30% withholding applies without proper tax forms.
I already have an EIN for my LLC. Do I still need an ITIN? The EIN is for your LLC. If you personally need to file a U.S. tax return (Form 1040-NR), you need an ITIN in addition to the EIN.
Can I apply for an ITIN without visiting the U.S.? Yes. An IRS Certified Acceptance Agent (CAA) verifies your passport remotely via video call. You never mail your passport or visit the U.S.
My ITIN is from several years ago — is it still valid? ITINs not used on a U.S. federal tax return in 2022, 2023, or 2024 expired December 31, 2025. Check yours and renew before filing if needed.
How much does ITIN service cost? ITINSERVICES charges $160 (Standard) or $170 (Priority). Both include full W-7 preparation and CAA passport verification. The IRS itself charges nothing.
ITINSERVICES is an IRS-listed Certified Acceptance Agent. We've handled ITIN applications for Amazon sellers from over 50 countries. The process is fully remote — no passport mailing, no U.S. visit.
