Best US LLC Formation Services for Non-US Founders (2026)

doola is the service most explicitly built for non-US founders — everything from the onboarding copy to the support team is designed around international entrepreneurs who've never touched a US tax form. You pick LLC or C-Corp, choose a state (Wyoming and Delaware are the most common), and doola handles formation, EIN (including for founders without an SSN), registered agent, and an operating agreement in a single flow. The EIN fetch is the big one: doola has an established workflow for IRS Form SS-4 fax filings that typically returns an EIN in 2–4 weeks, compared to the 2–3 months you'd wait filing solo.

What sets doola apart for this audience is the Total Compliance tier. Instead of paying a formation service plus a US CPA plus a bookkeeping tool separately, doola bundles bookkeeping (doola Books), annual state report filings, and US federal + state tax filings — including the dreaded Form 5472 + pro-forma 1120 that foreign-owned single-member LLCs must file yearly. For a solo SaaS founder in Europe or Asia billing $5–50k MRR through Stripe, this is the closest thing to an outsourced US finance department.

The dashboard is clean, support is genuinely responsive over email and chat, and they're used to dealing with founders in non-standard timezones and banking situations. Pair it with Mercury or Relay for banking and you have a functional US business you can operate from anywhere.

Firstbase.io sits squarely in the 'funded startup' lane. It was originally built for YC-style international founders forming Delaware C-Corps, and it still shows — the defaults, documents, and integrations all assume you're either already raising or plan to within 12 months. Formation includes Delaware C-Corp or Wyoming LLC, EIN fetch (SSN or no SSN), a registered agent, and standard startup paperwork like 83(b) elections, stock purchase agreements, and a SAFE-ready cap table.

For a non-US founder on the venture track, this matters enormously. Investors expect Delaware C-Corp with clean documentation. If you form a Wyoming LLC through a budget service and then try to convert two years later when you raise a seed round, you're looking at legal bills that dwarf what you'd have paid Firstbase upfront. Firstbase ships with the 'correct' structure out of the box, plus integrations with Mercury, Brex, Carta, Deel, and Stripe that shortcut the usual 'why won't this US platform accept my non-US ID?' friction.

The tradeoff is cost and scope. Firstbase is more expensive than Bizee or ZenBusiness, and unlike doola it doesn't include bookkeeping or tax filings in the base plan — you'll still need a CPA or a bookkeeping add-on for your annual Form 5472 and corporate tax return.

Stripe Atlas is the spiritual godfather of this category — the service that first made 'form a Delaware C-Corp from anywhere in the world' feel routine. If you're already a Stripe customer (and most non-US SaaS founders are), Atlas plugs straight into your Stripe dashboard: you get a Delaware C-Corp, EIN, US bank account introduction, and tax-ID support in one pass, with Stripe itself vouching for you to downstream partners.

For a non-US founder whose primary pain point is 'I need a US entity so Stripe will actually pay me out in my country,' Atlas is almost frictionless. The documents are AngelList/YC-style standard, the 83(b) election is handled, and the package now includes a year of free Mercury. Stripe's brand recognition also smooths things that would otherwise be annoying — when a US vendor asks for proof of incorporation, 'Stripe Atlas' answers the question instantly.

Where Atlas falls short for this audience: it's C-Corp-first (LLC is now offered but less emphasized), and there's no ongoing compliance wrapper. Once Atlas delivers your docs, you're on your own for state annual reports, franchise tax, Form 5472, and bookkeeping. If you're a hands-off solo founder, that's a lot to keep track of. If you're building a real company with a co-founder and eventual accountant, Atlas's clean foundation is worth the lighter ongoing support.

Northwest Registered Agent is the privacy specialist of this list. Their 'Privacy By Default' policy means they use their own US address on every public filing they can legally do so on — which is a bigger deal than it sounds when you're a non-US founder who doesn't want a random Wyoming public records database exposing a home address in another country.

For a non-US founder, Northwest shines in two scenarios. First, if you're forming a Wyoming LLC purely for asset protection and you want maximum anonymity in public filings, nobody does it better. Second, if you plan to DIY the EIN and tax filings with your own accountant, Northwest gives you a clean, reliable registered agent in any state ($125/year, which is actually included in the first year's formation fee) without bundling expensive add-ons you don't need.

The limitation: Northwest is not as aggressively international-focused as doola or Firstbase. They'll file your formation, act as registered agent, and help with EIN for an additional fee, but there's no integrated banking partner, no Form 5472 service, and no dashboard-driven ongoing compliance. You're expected to know what you need and ask for it — which is fine for a second-time founder, frustrating for a first-timer.

ZenBusiness occupies the 'friendly middle' of the LLC formation market: more polished than the $0 filers, less expensive than doola or Firstbase, and with a dashboard and support experience that doesn't assume you've formed a company before. For a non-US founder on a tight budget who wants an actual human to answer the phone if something goes sideways, ZenBusiness is a credible option.

The Pro and Premium plans include an EIN fetch, operating agreement, and annual worry-free compliance — which covers the state annual report filing that trips up a lot of first-year LLC owners. They also have an in-house Money Pro product that connects to a US business bank account, invoicing, and simple bookkeeping, though this is more US-SMB-flavored than the doola/Firstbase non-resident flows.

The caveats are real. ZenBusiness is built primarily for US-based small business owners — mechanics, consultants, Etsy sellers — and the non-US founder path works but isn't a first-class citizen. Expect to do more education of the support team about non-resident EIN requirements and banking, and don't expect the platform to handle Form 5472 for you. If your situation is standard (Wyoming LLC, no employees, simple SaaS or freelance income), ZenBusiness will serve you well. If it's complex, move up the list to doola.

Bizee (formerly Incfile) is the budget option — and unlike a lot of 'free' formation services, the $0 + state fee package is genuinely usable. You get LLC formation, one year of registered agent service, and filing of your articles of organization included. For a non-US founder who just needs a legal US entity to sign a contract, invoice a US client, or open a Stripe account, and who is comfortable managing taxes themselves, Bizee is the cheapest credible way to get there.

Where it makes sense for this audience: you're a freelancer or indie developer who wants a Wyoming LLC as a pass-through entity, you already have an accountant in your home country who can handle Form 5472 + pro-forma 1120, and you're banking with Wise Business or Mercury where non-resident onboarding is well-trodden. Bizee won't slow you down with features you don't need.

The real-world caveats: registered agent is free for year one but $119/year after, EIN is a paid add-on ($70), and there's no integrated compliance or tax service. If you forget to file your Wyoming annual report, there's no safety net. Bizee is a tool for founders who know exactly what they're doing and want to pay for only the filings themselves — not a shepherd through the process like doola or ZenBusiness.
