Once your Shopify or Amazon revenue gets real, the question arrives on schedule: "should I form a US company?" It touches payment approval rates, marketplace trust and liability — so it cannot be ignored forever. Here is the structure, the process and the honest cost.
The short answer first: a US LLC is a card you play after overseas revenue is proven — not a prerequisite for starting. You can sell on Shopify and Amazon as a foreign business. But there are real reasons many cross-border sellers eventually form one.
What a US LLC actually solves
- Payment infrastructure. A US entity plus a US bank account unlocks the full domestic rails — Stripe, better card approval rates, cleaner payout logistics.
- Marketplace trust. A US-entity seller account tends to face less friction with category approvals, disputes and payouts.
- Contracts and credibility. US wholesalers, 3PLs and partners move faster with a domestic counterparty.
- Limited liability. Business risk sits with the LLC, not your personal assets.
And what it does not solve: taxes do not disappear. If you are a foreign tax resident, your home country's rules still reach the LLC's income, and US filing obligations get added. An LLC is infrastructure, not a tax trick.
Delaware vs Wyoming
| Delaware | Wyoming |
|---|
| Reputation | The standard; investor-friendly | The pragmatic pick |
| Annual cost | Higher (franchise tax) | Lower |
| Privacy | Moderate | Strong |
| Fits | Fundraising plans | Solo ecommerce operations |
For a pure ecommerce operation with no fundraising plans, Wyoming's lower carrying cost usually wins. Note that sales tax follows your customers' states (nexus), not your state of formation — you cannot pick a state to escape it.

- 1. Registered agent / formation service. Stripe Atlas, Firstbase, doola and similar handle formation, address, EIN and banking in one flow — the common route for non-residents.
- 2. Formation. Company name and member details filed with the state; typically days.
- 3. EIN. The IRS tax ID that banking, Stripe and Amazon all require. Available to non-residents without an SSN; a service avoids the slow fax-and-mail route.
- 4. US banking. Fintech banks like Mercury or Relay onboard non-resident LLCs remotely. This unlocks Stripe.
- 5. Discipline. An operating agreement, and strict separation of company and personal money — mixing funds can pierce the liability shield.
Realistic costs and the traps
- Setup: a few hundred dollars with a service.
- Carrying: registered agent subscription + state annual report/tax + accounting. Budget roughly a thousand dollars a year as a floor.
- Filing: a foreign-owned single-member LLC must file with the IRS (Form 5472 attached to a pro-forma 1120) even with zero revenue — and the penalty for missing it is steep. A US CPA is not optional.
The two most common disasters: forgetting the annual state filing (penalties, administrative dissolution) and forgetting home-country reporting of foreign entities and accounts. Brief both a US CPA and your home-country accountant before forming. This article explains structure; execution needs professionals.
FAQ
Q. Can everything really be done remotely?
Yes — formation, EIN and bank account are all remote-friendly now. That is precisely what the one-stop services sell.
Q. Should I keep my home-country business entity?
Usually yes. Domestic sales, sourcing and costs run through the home entity; the LLC handles overseas payments and platforms. Transactions between the two entities raise transfer-pricing questions — design that with an accountant.
Q. When is the right time?
A practical bar: overseas revenue holding at a meaningful monthly level for a few months, plus a concrete payment or platform constraint that the LLC would remove. Before that, a Korean-entity Shopify setup is enough.
🧷 Key takeaways
- An LLC is payment/platform/liability infrastructure, not a tax hack — and it is a post-validation move.
- Wyoming for lean operations, Delaware if fundraising; sales tax follows customers either way.
- Remote path: service → formation → EIN → fintech bank → Stripe.
- The real cost is annual filings — a missed Form 5472 is an expensive mistake.
