US LLC for Vietnamese Founders: 2026 Stripe & Tax Guide

Vietnamese entrepreneurs run world-class digital agencies, game studios, and cross-border e-commerce brands. However, collecting international payments from US and European clients remains an obstacle. Stripe does not support Vietnamese business entities, and local merchant gateways charge exorbitant currency conversion fees that eat into thin margins.

A US LLC solves this bottleneck immediately. Operating through a US legal entity allows you to invoice corporate clients in USD, integrate official Stripe checkout on your websites, and hold funds in business checking accounts without forced conversion into VND. It also builds instant credibility with enterprise clients who hesitate to wire retainers to overseas domestic bank accounts.

Unlike forming a local entity with complex foreign investment certificates, a US LLC can be registered online within a few days. You retain complete ownership from Vietnam while operating under a respected international legal framework.

Most foreign founders default to Delaware because of its reputation among venture capital funds. If you do not plan to raise institutional equity from US venture capitalists in the next twelve months, Delaware is an unnecessary expense. Delaware charges an annual franchise tax of $300, and initial registered agent services typically run higher.

Wyoming is the standard choice for bootstrapped Vietnamese founders running service agencies, SaaS, or digital product shops. The Wyoming Secretary of State filing fee is $102, and the annual report fee is just $62 for assets under $300,000. Wyoming does not maintain a public registry of LLC members, which gives foreign founders built-in privacy.

New Mexico is another viable low-cost option with an initial fee of $50 and zero annual state franchise reports. However, some US merchant processors and payment providers scrutinize New Mexico entities more closely due to the complete lack of public records. For maximum compliance and banking approval rates, Wyoming remains the safest bet.

An Employer Identification Number (EIN) is your company's federal tax ID issued by the Internal Revenue Service. You cannot open a US business bank account or launch Stripe without it. Because you do not have a US Social Security Number or ITIN, you cannot use the IRS automated online portal.

Foreign founders must apply by submitting IRS Form SS-4 via international fax. On line 7b of the form, you write Foreign instead of an SSN. The IRS typically processes faxed applications within 20 to 30 business days, though seasonal backlogs can extend this timeline to six weeks.

Avoid hiring cheap filing agents who list their own staff as the responsible party on your SS-4. Fintech banks and payment gateways cross-reference your passport against IRS records. If the responsible party does not match the beneficial owner listed on your company documents, your banking applications will be rejected automatically.

Traditional US retail banks like Chase or Bank of America require physical presence inside a US branch to open an account. Non-resident founders must use fintech platforms like Mercury or Relay Financial, both of which support remote onboarding for Vietnamese citizens using valid international passports.

Underwriters at these platforms evaluate your business activity closely. To pass compliance, prepare a live business website on your own domain, matching company emails, clear descriptions of your digital services, and sample contracts or invoices. Generic landing pages or construction placeholders will trigger account denial.

You also need a commercial registered agent address or business address in the state of formation. Do not use cheap residential forwarding addresses that show up on residential databases. If you want a streamlined process without document errors, teams like Bastion Formations set up your entity, obtain your authentic EIN, and verify your paperwork for banking compliance.

Once your US bank account is funded, activating Stripe is straightforward if you input the right operational data. Register your Stripe account under your US company details, selecting United States as your business country. Enter your US business address, company EIN, and your US bank routing and account numbers.

When Stripe asks for identity verification for the business representative, choose Vietnam as the nationality and upload your Vietnamese passport. Do not buy fake SSNs or use synthetic US identities. Stripe explicitly allows foreign owners to represent a US business using their home country passport.

Always connect to your Stripe dashboard using your legitimate business network. While a secure dedicated IP is acceptable for remote work, using free or low-quality shared VPNs often flags anti-fraud algorithms, leading to manual reviews and rolling payout reserves.

A single-member US LLC owned by a non-resident is classified as a disregarded entity by default for US tax purposes. This means the entity pays no federal corporate income tax. Instead, tax liability passes directly to the foreign owner.

You only owe US federal income tax if your business generates Effectively Connected Income (ECI). ECI requires you to be Engaged in a Trade or Business in the United States (ETBUS). To be ETBUS, your company must have dependent agents or physical employees operating inside the US, or maintain a physical office, warehouse, or store on US soil.

If you write code, provide marketing services, or manage digital operations entirely from Vietnam without US personnel, your income is generally foreign-source income and not ETBUS. Under current IRS regulations, you owe 0% US federal income tax on those earnings. However, your profits remain subject to Vietnamese personal or corporate tax laws when remitted home.

Owing zero US tax does not mean you can ignore the IRS. Non-resident owners of single-member LLCs must file Form 5472 along with a pro forma Form 1120 every single year. This filing is purely informational, reporting reportable transactions such as capital contributions, loans, and owner withdrawals.

The deadline to submit these forms is April 15 of the following tax year. The penalty for failing to file on time or submitting inaccurate forms is $25,000 per violation. The IRS enforces this penalty aggressively against foreign owners.

Keep clean monthly records of every dollar entering and leaving your US account. Maintain separate business accounting and avoid mixing personal purchases with your business checking account to ensure your annual 5472 filing remains simple and audit-proof.
