US LLC for SaaS Founders Outside the US

If you are building a SaaS product from Europe and want Stripe, US customers, and a structure investors recognise, a US LLC is usually the fastest route in. Here is how it actually works, and what to file once it exists.

Why SaaS founders outside the US reach for an LLC

Most European SaaS founders do not need a US LLC to write code or land their first customers. They need one for the plumbing around the business: a Stripe account that does not get flagged, a US bank account for payouts, a US business address and phone number that make enterprise buyers comfortable, and a legal entity that a US investor or accelerator can actually put money into. An LLC solves all of this for a fraction of the cost and admin of a full US relocation.

Stripe in particular is the trigger for a lot of these formations. Stripe works in many European countries directly, but a US LLC with a US bank account often unlocks better platform stability, easier access to Stripe Billing and Tax features built around US business norms, and a cleaner story if you ever sell into the US market where buyers expect a US-based vendor.

LLC or C-corp, does it matter for SaaS?

For a bootstrapped or early-revenue SaaS business, a Delaware or Wyoming LLC is normally the right call. It is cheap to run, taxed on a pass-through basis by default, and gives you a real US legal entity without corporate double taxation. The catch is that most US venture capital funds cannot invest in an LLC, because their fund structures need a corporation to issue preferred stock. If you are planning to raise a priced round from US VCs, you will likely convert to a Delaware C-corp later, and many founders do exactly that: start as an LLC, convert once a term sheet is real. Starting as an LLC does not burn this bridge, it just delays the more expensive corporate structure until you actually need it.

What you need in place

• A registered LLC in a US state, with a registered agent there
• An EIN (Employer Identification Number) from the IRS, this is your business tax ID
• A US business bank account, and ideally a US business card for tools, ads, and hosting
• A US mailing address for banking and Stripe verification
• An ITIN for yourself if you plan to file a personal US tax return or a bank specifically requires it, though this is not needed to form the LLC or get an EIN

None of this requires a US visa or a US Social Security Number. An ITIN is issued to people who are not eligible for an SSN and need a US taxpayer number for filing purposes, it has nothing to do with immigration status. An EIN for a foreign-owned LLC is obtained through Form SS-4, and non-residents apply by fax or mail rather than the online portal, since the online EIN application is reserved for applicants with an SSN or ITIN.

Choosing a state

Wyoming is the default choice for most non-US SaaS founders who are not raising US venture money soon. It has no state income tax on LLC income, low annual fees, and a straightforward annual report. Delaware is worth the slightly higher cost if you already know you are heading toward VC funding, since investors and their lawyers are most familiar with Delaware corporate law and it makes a future C-corp conversion smoother. Neither state requires you to live there or visit.

Getting from zero to a working stack

The realistic order of operations looks like this: form the LLC and get your certificate, apply for the EIN, open the business bank account once the EIN is issued, then connect Stripe using the EIN, business address, and bank details. Mercury, Wise Business, and Relay all accept applications from non-resident founders remotely, and Stripe onboarding is generally smoother once you have a real US bank account behind the LLC rather than only a virtual card provider. EIN processing by fax for non-residents typically takes a few weeks, so this is the step that sets the pace for everything else.

The compliance side nobody mentions upfront

A foreign-owned single-member LLC is a disregarded entity for tax purposes, which sounds like it means nothing to report. It does not. The IRS requires you to file Form 5472 alongside a pro-forma Form 1120 every year, even if the LLC had zero revenue or was dormant. This is an information return, it reports transactions between the LLC and its foreign owner rather than calculating tax owed on its own, but skipping it carries a penalty of $25,000 for a first violation. If your SaaS genuinely has no US trade or business (common when your customers, servers, and team are outside the US and Stripe simply routes payments through the LLC), you may owe little or no US federal income tax, but the 5472 and 1120 filing obligation exists regardless of profit. You will also owe your state's annual report and franchise fee to keep the LLC in good standing.

Where founders usually get stuck

The common failure points are not legal complexity, they are logistics: EIN applications rejected for a badly filled SS-4, bank applications stuck because the LLC formation documents do not match what the bank expects, or 5472 deadlines missed because nobody flagged them a year later when the founder is deep in product work. This is the gap Founders Credit is built to close. We handle the LLC formation, EIN application, ITIN if you need one, and get you into a US bank account and business card, then keep you on track for the annual filings so a missed deadline never turns into a five figure penalty.

Investor readiness, beyond the entity

If you are fundraising or expect to soon, investors will look past the entity type to the basics: is the cap table clean, is the LLC agreement (or future stockholders' agreement) unambiguous about ownership, are the 5472 filings up to date, and is there a US bank account showing real business activity rather than a shell. Getting these right from day one, even at pre-revenue stage, makes a future Delaware C-corp conversion during a raise a paperwork exercise rather than a scramble.
