Register a US company from Vietnam, without leaving home.
Formation, EIN without an SSN, and US bank-account guidance — the whole US setup run remotely by a CPA firm, so a manufacturer or Amazon seller can reach US marketplaces and hold revenue in dollars instead of routing everything through onshore currency controls.
For a Vietnamese manufacturer or seller, a US company is the step from making the product to owning the US sale.
Vietnam has become one of the world's manufacturing hubs, and a growing number of factories and OEM suppliers no longer want to stop at the factory gate. Selling directly on Amazon US — under your own brand, capturing the retail margin rather than the wholesale one — needs a US-facing entity, an EIN, and US banking behind a professional seller account. That manufacturing-to-marketplace arc is the reason most Vietnamese founders reach us.
Currency is the other half. Receiving and holding USD onshore in Vietnam runs into the State Bank of Vietnam's foreign-exchange rules, so keeping your marketplace revenue in a US account you control removes friction and gives you timing over when funds come home. The work is to build that US presence correctly — a real entity, a consistent identity, and a filing calendar that stays handled — so the access you set it up for doesn't come with a compliance surprise later.
The full US setup, from Vietnam
The same spine we run for every international founder, adapted to how Vietnamese manufacturers and Amazon sellers operate.
Entity & state choice
A single-member LLC is the usual fit for an FBA or D2C brand; a Delaware C-Corp is for founders raising US capital. We match the state — commonly Wyoming, Delaware, or Florida — to how you'll operate. Weighing the options? Our US company cost calculator compares filing and annual costs.
EIN without an SSN
Without a US Social Security Number, the IRS online tool is closed to you, so the EIN goes through Form SS-4 by fax — roughly 10 to 14 days or more as of 2026. We prepare and submit it and track it to issuance; here's how getting an EIN without an SSN actually works.
US bank account, remotely
Options such as Payoneer, Wise, Mercury, and Relay are well used by Vietnamese sellers to open US business banking without flying over. We prepare your documentation so the application meets the bank's checks — more on opening a US business bank account as a non-resident. The bank makes the final call.
Vietnam–US treaty not in force
The US and Vietnam signed an income tax treaty in 2015, but it was never ratified by the US Senate and is not in effect. There's no treaty rate to fall back on, so your US position turns on whether your income is effectively connected to a US trade or business. We base your setup on that reality, not on a treaty that hasn't taken effect.
Form 5472 & annual duties
A foreign-owned single-member LLC must file Form 5472 with a pro-forma 1120 every year, even with no activity — the form that carries a $25,000 penalty if missed. We set the calendar and file on time, alongside your state annual report.
Marketplace KYC consistency
Amazon and other marketplaces verify that your entity name, EIN, address, and banking match across every record. We keep those details consistent from day one so verification doesn't stall your seller account.
What tends to matter for founders in Vietnam
A few realities specific to setting up from Vietnam, so there are no surprises.
From factory to your own US brand
Moving from OEM production to selling under your own label on Amazon changes what the US side carries — brand ownership, marketplace standing, and a clean entity behind it. We set the US company up so it can hold your brand and grow into Brand Registry rather than looking like a pass-through.
Working around onshore USD controls
Holding and receiving dollars inside Vietnam runs into State Bank of Vietnam foreign-exchange rules. Keeping revenue in a US account you control sidesteps that at collection and lets you decide when to remit home — Vietnamese reporting on foreign income still applies, and we coordinate on it.
Register truthfully as a foreign owner
The common trap is claiming a US operational address you can't back with a utility bill. For Vietnamese sellers it's cleaner to register truthfully as a foreign-resident owner — we set the entity and records up that way so Amazon's checks don't rebound on you later.
Effectively-connected-income analysis
With no treaty in force, whether US income tax is owed rests entirely on whether your income is effectively connected to a US trade or business. That analysis carries extra weight for Vietnamese founders because there's no treaty to soften it, so we do it deliberately rather than guessing.
Questions from founders in Vietnam
General information to help you plan. Your specifics may differ — that's what the first conversation is for.
Is there a Vietnam–US tax treaty?
The United States and Vietnam signed an income tax treaty in 2015, but it has never been ratified by the US Senate and is not in force. As of 2026 there are no treaty benefits to rely on, so your US position turns on whether your income is effectively connected to a US trade or business. We base your setup on the rules that actually apply rather than on a treaty that hasn't taken effect.
Do I need to visit the US to register the company from Vietnam?
No. Founders in Vietnam can form and run a US company entirely from home. Formation needs your passport, not travel or a US visa. We file everything remotely and coordinate the steps that touch a US institution, such as the bank application.
Can I keep my Amazon earnings in dollars outside Vietnam's currency controls?
A US company with a US bank account lets your marketplace and processor payouts land and stay in dollars in the United States, rather than being routed onshore and converted under Vietnam's foreign-exchange rules at each settlement. You decide when to bring funds into Vietnam, which is a big part of why manufacturers and sellers set one up. Vietnamese reporting on foreign income and remittances still applies, and we coordinate on that.
How does Amazon verification work from Vietnam?
Amazon verifies that your entity name, EIN, address, banking, and tax interview all match, and that you register truthfully as a foreign-resident owner rather than claiming a US operational address you can't document. Vietnamese factories and sellers moving to a US entity often trip on inconsistent records; we set yours up consistently from the start so verification is a formality, not a weeks-long stall.
