What is an ITIN?
Your gateway to the US financial system.
If you own a US LLC, earn US income, claim a tax-treaty benefit or are named on a US return — and you don’t have an SSN — an ITIN is how you stay compliant. Here’s what it unlocks:
Open US bank & payment accounts
Required by many US banks and processors to open accounts as a non-resident.
File your US tax returns
Mandatory if you earn US-source income, run a US LLC or own US property.
Get paid by US platforms
Amazon, Stripe and PayPal require a US tax ID for non-US sellers to receive payouts.
Who needs an ITIN
If any of these sound like you,
you likely need one.

Non-resident US business owners
You own a US LLC or corporation and need a tax ID to file, claim refunds or open accounts.
Filing US taxes as a non-resident
You need to file a US tax return as a non-resident — an ITIN is required before you can file.
Tax-treaty benefit claims
You're claiming reduced withholding under a tax treaty and need an ITIN to do it.
Spouses & dependents
You're named on a US tax return as a spouse or dependent without an SSN.
Marketplace & platform sellers
You sell on Amazon, Etsy or similar and a platform requires a US tax ID for payouts.
US-source payments & refunds
You've had US tax withheld and need an ITIN to file and reclaim what you're owed.

Frequently Asked Questions
How long does it take to get an ITIN?
Normally, it takes about 8 to 12 weeks to receive your ITIN. However, processing times can vary depending on IRS workload and the time of year (tax season often takes longer).
Do I have to send my original passport to the IRS?
No. As a Certified Acceptance Agent we verify and certify your identity documents directly, so you keep your original passport instead of mailing it overseas to the IRS.
I just need a US company too — can you do both?
Absolutely. Many clients bundle ITIN with our company setup & EIN service so everything is handled together — at a discount.
Can you get ITINs for my spouse and dependents?
Yes. We handle applications for owners, spouses and dependents, and can bundle several together at a family rate.
