From South Korea · Asia-Pacific
Stripe doesn't take Korean businesses, so founders in South Korea form US companies to take card payments, sell to US customers and raise from US investors. Mercury opens accounts for founders living there.
Mercury opens accounts remotely for founders living in South Korea. The banks, in detail.

01What changes because you live here
The tax treaty, whether Stripe will take you, which banks will open an account, and the time difference. Each was checked against its source in September 2026.
The tax treaty
In force
The United States and South Korea have an income tax treaty in force. It can lower the US tax withheld on dividends, interest and royalties paid to you, if you claim it on a W-8BEN with your Korean tax number, and it settles which country taxes what when both could.
Stripe
Not available locally
Stripe doesn't take businesses registered in South Korea. A US LLC with an EIN and a US bank account is a US business, so it can apply for a US Stripe account, and that's often the main reason founders in South Korea form one.
Banking
Mercury available
Mercury opens accounts remotely for US companies whose founders live in South Korea. It asks for the EIN, the formation documents, your passport, a real business address and a description of the company's existing or planned US operations. Relay asks a non-US owner for a US address, an ITIN or Social Security Number and a US operating presence, so it rarely suits a founder living in South Korea.
The time difference
UTC+9
New York is 13 hours behind South Korea in summer. Everything we do is in writing, through your dashboard and email, and we reply within one business day, so the time difference rarely slows anything down.
Checked in September 2026 against the IRS list of tax treaties, Stripe's country page, and Mercury's and Relay's published country lists. If something here has changed, email us and we'll correct it the same day.
02What South Korea expects
South Korea taxes its residents on income from anywhere in the world. Whether the LLC's profit counts as yours as it's earned, or only when you take it out, depends on how South Korea treats a US LLC, and that's a question for a local tax adviser.
What founders here build
04What it costs
Charged once, in US dollars, with the Wyoming state fee passed on at cost. Where you live changes which bank we introduce you to, not the price.
Extras are optional, and the order form asks about each one with its price. Filing yours ahead of our next batch costs $75, and we email you before anything renews. Delaware, and every extra with its price, are on the pricing page.
05Questions
If yours is not here, email us at [email protected] before you order.
Yes. The United States doesn't require an LLC's owners to be US citizens or residents. You'll need a registered agent in the state, which every plan includes, and your passport for the bank. The filing is the same wherever you live. What changes is the tax treaty, the payment processors and the banks, which this page covers.
No. The filing, the EIN, the operating agreement, the bank application and the payment processors are all handled online. You don't need a visa or a trip.
The United States and South Korea have an income tax treaty in force. It can lower the US tax withheld on dividends, interest and royalties paid to you, if you claim it on a W-8BEN with your Korean tax number, and it settles which country taxes what when both could.
You can apply. A US LLC with an EIN and a US bank account is a US business, and Stripe reviews it on its US terms. Approval isn't automatic: Stripe looks at the business, its website and the person behind it, and it can say no. Honest, consistent details and a real website give you the best chance.
