For a non-US founder, the LLC wins in almost every case. A sole proprietorship needs no registration and costs nothing to start, but it gives you no liability protection, no separate business identity, and almost no way to get a US EIN, open Stripe, or hold a US business bank account without a Social Security Number. An LLC costs $100 plus the state fee to form, and in return you get limited liability, a free EIN from the IRS on Form SS-4, access to Stripe and US business banking, and a structure that clients and partners actually trust. The only founders who should stay sole proprietors are those testing an idea with zero revenue and zero risk.
The rest of this guide explains exactly why the math is so one-sided for foreign founders, compares both structures side by side, and lays out the steps to take next.

Why this decision is different for foreign founders
For a US citizen, “sole proprietorship” means starting work tomorrow with no paperwork. The IRS and the SBA both describe it as the simplest business structure: no separate entity, no state filing, and income reported on the owner’s personal tax return. For a US resident doing low-risk freelance work, that simplicity can be a reasonable choice.
For a non-US founder, that simplicity is mostly an illusion. Every practical benefit of a US business presence depends on things a foreign sole proprietor cannot get: a Social Security Number, a US address, and a legal identity separate from your personal one. Stripe’s US onboarding asks for an EIN or SSN. Banks ask for formation documents. Clients hesitate before wiring thousands of dollars to a personal name in another country. The sole proprietorship’s main selling point, that it requires nothing, becomes its main weakness: it gives you nothing to show.
An LLC fixes this with a single state filing. It creates a legal entity independent of you, able to hold its own EIN, bank account, and contracts, while remaining one of the cheapest structures in the world to set up. If you are still fuzzy on the basics, start with our plain-English explainer on what an LLC is and how it works before reading on.
LLC vs sole proprietorship: the comparison table
| Factor | Single-member LLC | Sole proprietorship |
|---|---|---|
| Legal entity | Separate legal person; owner liability is limited to the investment in the business | You ARE the business; no legal separation |
| Personal liability | Generally limited: business debts and lawsuits stay with the LLC | Unlimited: creditors can reach your personal savings and assets |
| Formation cost | State fee (roughly $50 to $400 by state, as of October 2026) plus any service fee | $0; nothing to file |
| EIN | Yes: free from the IRS; foreign founders apply on Form SS-4 by fax or mail | Practically no: the IRS online application requires an SSN or ITIN, which most foreign founders lack |
| Stripe and payments | Works: a US LLC with an EIN can activate Stripe, PayPal Business, and similar tools | Very difficult: processors typically require an SSN or a US business entity |
| US business bank account | Yes: fintech banks accept LLCs with an EIN | Nearly impossible without an SSN and US residency |
| Taxes | Single-member LLC defaults to “disregarded entity”: profits pass through to the owner. Foreign-owned LLCs must file Form 5472 plus a pro-forma Form 1120 yearly | Pass-through too, but with no entity, all income lands on your personal return and cross-border reporting gets messy |
| Annual compliance | Annual report or franchise tax in most states (Delaware’s LLC tax is $400 from 2026) | None |
| Credibility | High: invoices, contracts, and transfers carry a company name | Low: clients pay a personal name abroad, raising trust and compliance questions |
| Best for | Foreign founders who want to actually run a US business | Testing an idea with no revenue, no clients, and no legal exposure |
Liability: the biggest difference
Liability protection is the reason the LLC exists, and the strongest argument for a foreign founder. In a sole proprietorship, there is no wall between you and the business. If a client sues over a missed deadline, a supplier claims nonpayment, or a product causes harm, the claim is against you personally. Defending a US lawsuit from another country is expensive, slow, and weighted toward the side with local representation.
An LLC draws a legal line: debts, contracts, and lawsuits belong to the company, and your personal savings and assets are generally off limits as long as you keep the LLC’s finances separate from your own. That separation is doing real work: you need a dedicated bank account, clean books, and an operating agreement. Forming the LLC is the start of the protection, not the whole of it.
One caveat: an LLC does not protect you from your own wrongdoing. If you commit fraud or sign a personal guarantee, the entity will not shield you. It protects you from the ordinary risks of running a business: disputes, debts, and claims against the company.
Stripe, payments, and banking
This is where the sole proprietorship route breaks down completely for most foreign founders. Accepting payments from US and international customers is usually the whole point of forming a US presence, and payment infrastructure is built around entities, not individuals.
Stripe’s US activation requires a US business structure with an EIN (or an SSN for individuals). A foreign founder without an SSN cannot complete individual verification, so a sole proprietorship leaves Stripe effectively out of reach. With a single-member LLC and an EIN, you can activate Stripe, PayPal Business, and most other processors. Our walkthrough on how to use Stripe with a US LLC as a non-resident covers the exact documents Stripe asks for.
Banking tells the same story. Fintech banks that serve foreign founders, such as Mercury, require formation documents and an EIN, which means an LLC or other registered entity. A sole proprietorship has no formation documents at all, and without an SSN there is no personal identity to open a business account against. Some founders route money through personal Wise accounts, but that mixes personal and business funds, looks unprofessional, and complicates your tax reporting.
Taxes: what each structure actually costs you
Both structures are pass-through for US federal tax, which surprises some founders: neither an LLC nor a sole proprietorship pays federal income tax at the entity level by default. A single-member LLC is a “disregarded entity,” meaning the IRS treats it as inseparable from its owner, and profits flow to the owner’s tax return. A sole proprietorship reports the same way, on Schedule C.
For a foreign founder, the LLC still wins on taxes for three practical reasons.
First, it gives you a clean container: income, expenses, and deductions live inside one entity with one EIN, which makes bookkeeping and cross-border reporting far simpler than tracing business activity through personal accounts.
Second, it is the structure cross-border accountants actually work with. Where you are tax-resident, whether your income is effectively connected with a US trade or business, and how your home country treats a US disregarded entity all shape what you owe.
Third, one compliance obligation you must know about: a single-member LLC that is 100 percent foreign-owned must file Form 5472 with a pro-forma Form 1120 every year by April 15, reporting transactions between the LLC and its owner. The IRS penalty for missing it is $25,000 per year. It is an informational return, not a tax bill, and our dedicated Form 5472 guide for single-member LLCs walks through it line by line.
The honest trade-off: an LLC adds annual compliance a sole proprietorship skips, mainly the state annual report or franchise tax and Form 5472. Budget for it, calendar the deadlines, and the cost is small relative to what the structure unlocks.
Credibility and contracts
Money follows trust, and an entity is a trust signal. “Acme Labs LLC, Wyoming, EIN on file” on an invoice tells a client three things: this business is registered with a US state, it has a tax identity, and it can be looked up in a public registry. A personal name with a foreign bank account tells the client none of that, and enterprise clients and marketplaces increasingly run vendor compliance checks that a sole proprietor cannot pass.
Contracts are cleaner too: an LLC signs in its own name and owns its intellectual property. If you later add a co-founder or sell the business, transferring membership interests is a standard process. A sole proprietorship cannot be transferred, because there is nothing separate from you to transfer.
Real costs: DIY vs using a formation service
The price gap between the two structures is smaller than most founders expect. A sole proprietorship costs $0. An LLC costs the state filing fee, which varies: New Mexico charges $50 with no annual report, Wyoming charges $100, and Delaware’s annual LLC tax is $400 from tax year 2026 (raised from $300 by Delaware House Bill 400). Figures are as of October 2026; always verify the current fee on the Secretary of State website before filing.
You can file yourself, but as a foreign founder you also need a registered agent with a physical address in the formation state, which you cannot provide yourself. That is where a formation service pays for itself. Registered Agents Inc charges $100 plus the state fee for the full bundle: the state filing, a domain name, a website, and one year of free registered agent service. Their standalone registered agent service is $200 per year, and standalone domains start at $4.95 per year. Add-on tools for a website, phone, and email run $5 per month each, so check current pricing on any add-ons before ordering.
What to do next: 6 steps
If you have decided the LLC is right, here is the exact sequence. Foreign founders can complete nearly all of it remotely.
Step 1: Choose your state
Wyoming, New Mexico, and Delaware are the most popular picks for non-US founders: low fees, no state income tax on pass-through income, and founder-friendly rules. Delaware’s $400 annual LLC tax from 2026 makes it pricier than Wyoming or New Mexico for a simple online business.
Step 2: Form the LLC and appoint a registered agent
File Articles of Organization with the Secretary of State and name a registered agent with a street address in that state. Or let Registered Agents Inc handle the filing for $100 plus the state fee, which includes the first year of registered agent service.
Step 3: Get your EIN from the IRS
The EIN is free. Without an SSN or ITIN, you cannot use the IRS online application; instead, complete Form SS-4 and fax or mail it to the IRS. Expect about 4 to 6 weeks. Our guide on how to get an EIN as a foreigner has the fax number, the exact form fields, and what to do if the IRS sends questions back.
Step 4: Open a business bank account
With your approved Articles of Organization and EIN, apply to a fintech bank that serves foreign founders. Keep a personal bank statement and your passport ready; most applications are fully online.
Step 5: Activate Stripe and start selling
Connect your EIN, bank account, and formation documents to Stripe or PayPal Business. Use the LLC’s legal name consistently across Stripe, your bank, and your contracts.
Step 6: Calendar your compliance
Mark two recurring obligations from day one: your state’s annual report or franchise tax, and Form 5472 with the pro-forma Form 1120 every April 15. Missing either one is the most common and most expensive mistake foreign LLC owners make.
FAQ
Can a foreigner be a sole proprietor in the US?
Technically yes: US law does not require citizenship to do business as a sole proprietor. Practically, it is a dead end for most foreign founders. Without an SSN you cannot get an EIN online, which blocks Stripe, PayPal Business, and US business bank accounts. You also have unlimited personal liability. An LLC solves all three problems with one filing.
Is an LLC worth it if I have no revenue yet?
Usually yes, if you plan to charge clients or accept payments within the next few months. The LLC costs $100 plus the state fee once, and it gives you the EIN, Stripe access, and liability protection you will need anyway. Staying a sole proprietor only makes sense while you are purely testing an idea with no customers, no contracts, and no money moving.
Does a single-member LLC pay US taxes?
By default, no tax at the entity level: a single-member LLC is a disregarded entity and profits pass through to the owner. But “pass-through” does not mean “tax-free.” Whether you owe US tax depends on whether the income is effectively connected with a US trade or business and on your country of residence. Foreign-owned single-member LLCs must also file Form 5472 annually. Talk to a cross-border accountant before assuming you owe nothing.
What is Form 5472 and does it apply to me?
Form 5472 is an IRS information return that reports transactions between a foreign-owned US entity and its foreign owner. If you are a non-US person who owns 100 percent of a single-member LLC, it applies to you. It is filed with a pro-forma Form 1120 by April 15 each year, and the penalty for not filing is $25,000 per year. It is informational, not a tax payment.
Can I get an EIN without an SSN as a sole proprietor?
Only with difficulty. The IRS online EIN application requires an SSN or ITIN for the responsible party. Without either, you can apply by fax or mail on Form SS-4, or apply for an ITIN first, which adds months. An LLC does not change the IRS rules, but it gives you a proper business entity to attach the EIN to, which is what banks and payment processors expect to see.
LLC vs sole proprietorship: which is better for freelancers abroad?
For freelancers with international clients, the LLC is better in nearly every case. It separates your personal assets from client disputes, lets you invoice under a company name, and unlocks Stripe and US business banking. A sole proprietorship saves you the formation fee but leaves you personally liable and locked out of the payment infrastructure most freelancers depend on.

Conclusion
A sole proprietorship is free and instant, but for a non-US founder it is free in the way a rowboat is free for crossing an ocean. It offers no liability protection, no EIN path that works in practice, no Stripe, no US business bank account, and no credibility with clients. An LLC costs $100 plus the state fee and delivers all of it: a separate legal entity, limited liability, a free EIN, payment processing, banking, and a name clients trust. The annual compliance, a state report and Form 5472, is real but manageable.
If you are ready to set yours up, form your LLC with Registered Agents Inc for $100 plus the state fee, including the state filing, a domain name, a website, and one year of free registered agent service. Check current pricing before ordering, get your EIN on Form SS-4 as soon as the LLC is approved, and calendar your Form 5472 deadline from day one.
