Stripe does not require an ITIN from a non-US owner of a US company. Its support article on tax ID requirements for US companies says a business representative who is a US individual lists an SSN, or an ITIN without one, and that a representative who is not a US individual and has neither provides a local non-US tax ID with documentation confirming they are not a US taxpayer; at $500,000 of lifetime payment volume Stripe asks every listed owner for the last four digits of their SSN or ITIN (support.stripe.com, read September 14, 2026). For a non-US store owner the number's job is elsewhere: the US bank account the payouts land in, the cards that fund inventory and advertising, and any US return in the owner's name.
Does Stripe require an ITIN?
No. Stripe's support article on tax ID requirements for US companies, read September 14, 2026, sets out three cases. A business representative who is a US individual lists a Social Security number. A US individual without an SSN lists an ITIN. A representative who is not a US individual and has neither provides a local non-US tax ID and documentation confirming they are not a US taxpayer. The same article says representatives give the last four digits of their SSN or ITIN at onboarding and that, at $500,000 of lifetime payment volume, every listed owner confirms those digits; Stripe's required verification information page carries the full table. For a non-US founder running a US company, the passport and the home-country tax number do the identification at Stripe; the ITIN is accepted, not required.
That requirements page also lists the business's tax ID number, the EIN for a US company, and an external account for payouts, which pause without one. That external account is where the ITIN enters the picture.
What about Shopify Payments?
Shopify Payments' terms of service, read September 14, 2026, make you identify the Designated Country you operate the business from and confirm that you are either a legal resident of that country or a business entity duly established and, where necessary, registered to conduct business there. The terms also say the payment processor runs its own know-your-customer and anti-money-laundering checks, and that payouts go to the bank account you designate in your Shopify admin. The help-centre page that lists the personal information Shopify asks for at setup refused every automated read we attempted that day, so we quote nothing from it; read it when you enable payments. The store owner who is not American arrives at the same two questions as at Stripe: how are you identified, and where does the money land.
Where the ITIN actually matters for a store owner
| Need | ITIN needed? | Why |
|---|---|---|
| Opening the Stripe account for a US company | No | A non-US representative without an SSN or ITIN provides a local tax ID and documentation (Stripe support, September 2026). |
| The US bank account the payouts land in | Yes, in practice | A national bank identifies a non-US owner by passport and taxpayer number and opens in person. |
| US credit cards for inventory and ads | Yes | Issuers file the owner's history under the number; without it there is no file. |
| The owner's US return, if one is required | Yes | The W-7 is filed with it. Whether a return is required is your adviser's question. |
| Form 5472 for a foreign-owned single-member LLC | SSN or ITIN, if any | The instructions ask for the owner's US identifying number. |
| Receiving payouts at a fintech | No | Mercury lists formation documents, the EIN and a passport as its requirements. |
The bank behind the processor
Every processor moves money to a bank account, and the account decides how the business feels. A fintech account opens online on the company's EIN and a passport, which is why most non-US stores start there. It also has no branch, no banker and statements that other institutions discount. Our client who runs an e-commerce brand from Latvia, with a US warehouse to pay, put it in five words: no one trusts a Mercury bank statement. That founder's base today is Bank of America, Chase and Capital One, opened in person, on an ITIN.
A store on Shopify or Stripe lives on advertising and inventory paid before the sale. Cards that give something back on that spend, at 0 percent for the first year, and a banker who knows the business exist on the other side of the branch door. The number that opens it is the same one that identifies you to the IRS.
Chargebacks, holds and why a real account matters
Processors hold funds. The video below explains why Stripe or PayPal can hold a founder's money for up to 180 days, what triggers it, and why a real US bank account behind the processor changes the odds. The short version: the more of your financial life a US bank can see, the less any single platform's decision can stop you.
How a store owner gets the ITIN
Form W-7 with a valid passport, filed with the return that needs the number or under one of the five exceptions in the instructions; the IRS allows 7 weeks, 9 to 11 in the January 15 to April 30 peak or from abroad, and charges nothing. Through a Certifying Acceptance Agent the passport is verified in a live video session and certified, so it never travels. Our fee is $399, refundable until we file. Then the company's documents, the accounts in Miami, the cards. The order guide shows the sequence.
