Starting a Business in the US: LLC vs. Sole Prop vs. Corporation
You don't need US citizenship or even a green card to own a US business — but some visa holders can't actively work in it.
In short: Almost anyone — regardless of citizenship or even immigration status — can own a US business. The three basic structures are sole proprietorship, limited liability company (LLC), and corporation. What actually matters for visa holders isn't ownership, but active work in the business, which can require separate work authorization.
The three basic legal structures
Per the IRS, the most common business forms are: sole proprietorship, partnership, corporation, and the LLC, which is governed by each state's own statute.
- Sole proprietorship: The simplest form — usually no separate formal registration beyond a trade name if needed — but there's no separation between your personal assets and business debts. Your liability is unlimited.
- LLC: Legally separates your personal assets from the company's obligations. For tax purposes it can be treated as a sole proprietorship, partnership, or corporation, depending on the election you make when registering with the IRS.
- Corporation: More administratively complex, and can face double taxation (at the company level, then again on dividends to shareholders for a C-corp), but it's the better fit if you plan to raise significant investment later.
Quick comparison of the three structures
| Criterion | Sole proprietorship | LLC | Corporation |
|---|---|---|---|
| Protection from personal debt | None | Full legal separation | Full legal separation |
| Administrative complexity | Lowest | Medium | Highest |
| Default taxation | Flows to personal return | Pass-through to personal return unless you elect otherwise | Usually double taxation for a C-corp |
| Best fit for | Simple, low-risk solo activity | Most small and mid-sized businesses | Those planning to raise significant investment or issue stock |
Practical setup steps
- Choose the right structure. Based on your business size, expected liability, and future plans.
- Register in the state where you actually operate. It's usually simplest to register in the same state where you actually do business, not another state for "lower taxes" unless you understand the cost of dual registration.
- Get an EIN. Free from irs.gov, and required to open a bank account, hire employees, and file your tax returns. See our EIN guide for full details.
- Open a dedicated business bank account. Separating personal and business accounts is legally and tax-wise necessary — see our bank account guide.
- Get the necessary licenses. Use the official SBA tool to find which licenses your specific activity and location require.
- Set up bookkeeping from day one. Makes filing your tax return much easier, especially if you plan to work with an accountant later.
Immigration status limits: ownership isn't work
Important: Work-visa holders (like H-1B) or student-visa holders (F-1) can generally own a business only as a "passive investor" — no day-to-day management, operational decisions, or compensation for their own labor in it. Actually performing work (signing contracts, managing employees, delivering services) can be treated as unauthorized employment affecting your status. This is a general rule, not legal advice — consult an immigration attorney before taking any practical step if you're on a non-green-card visa.
Green card holders don't face this limit; they can own and actively work in their business freely, like any US citizen.
Annual obligations after registering: it doesn't stop at step one
Forming a company isn't a one-time event. Most states require filing an annual report or paying a franchise tax to keep your business in "good standing" with the Secretary of State; fees and deadlines vary completely by state, so check your own state's Secretary of State website and put the renewal date on your calendar right after formation. Neglecting this can lead to administrative dissolution without much warning, which costs you the legal protection you formed the company for in the first place.
If your business hires employees, you'll also need to register for state unemployment insurance separately from your federal EIN, and possibly a sales tax permit if you sell tangible goods. These are additional obligations unrelated to the LLC registration itself, but legally necessary once your business grows.
Taxes: a point many overlook
In a single-member LLC, the company is by default treated for tax purposes as a "disregarded entity," so its profits flow into your personal return without a separate company filing, unless you elect to be taxed as a corporation. This simplifies things at first, but it also means company profits are taxed as personal income whether or not you actually withdraw them. See our US taxes guide for the full picture before you start.
Choosing your business name and checking availability
Before registering, verify your proposed business name is available in your state's registry (usually through the Secretary of State's website), and that it doesn't conflict with a federally registered trademark via the USPTO's free database. If you want to operate under a name different from your LLC's official registered name (for example, an LLC registered under your personal name but trading under your brand), you'll need to register a "doing business as" (DBA) name with your state or county — a separate step from the LLC registration itself.
Worked example: how tax works for a single-member LLC
Say your business earns $60,000 in net profit for the year, and you're the sole owner of an LLC that hasn't elected to be taxed as a corporation. The company itself doesn't pay a separate federal income tax; instead, that full $60,000 flows onto your personal tax return (Form 1040 with Schedule C), subject to ordinary federal income tax plus self-employment tax, which covers your share of Social Security and Medicare as a self-employed person. This means you may need to make estimated quarterly tax payments instead of waiting for annual filing season, to avoid an IRS underpayment penalty.
When do you actually need a lawyer or accountant?
You can register a simple LLC yourself without a lawyer in most states, but consult a small-business attorney if you have multiple partners (to draft a clear operating agreement that prevents future disputes), or if your business is in a regulated sector requiring complex licensing. An accountant is worth bringing in from roughly your first year for anything beyond simple solo work, especially to understand estimated quarterly taxes and to evaluate whether later electing S-corp tax treatment would save you money.
Practical notes for Arab founders and newer residents
You don't need a Social Security number to form an LLC or even to get an EIN; you can submit Form SS-4 to the IRS by fax or mail as a foreign national without an SSN. This is especially useful if you're running a business from abroad or just arrived and haven't gotten your number yet. If you don't have a permanent US address, registered agent services exist in every state to receive official mail on your behalf for an annual fee — this is legally required in most states regardless of your immigration status.
If you're planning a business that's meant to be Sharia-compliant (avoiding interest-based financing, or ensuring your product is halal), that doesn't change the legal registration process itself; your business structure (LLC or otherwise) is entirely separate from how you finance the business or what you sell. What actually matters is choosing a bank or finance institution offering compliant options if you need them later to fund your company's growth.
Common mistakes
- Mixing personal and business accounts. Weakens the legal protection an LLC provides and complicates your tax filing.
- Actively working in the business on a visa that doesn't allow it. Can put your entire immigration status at risk.
- Ignoring local licenses. Some activities (food, healthcare, construction) need special licenses before you can legally start.
- Not understanding the tax difference between an LLC and a corporation. A wrong call here can cost thousands of extra dollars a year.
What's next
Start by getting your free EIN directly from the IRS, then open a business bank account separate from your personal one, and review our US taxes guide to understand your annual obligations before your business's first tax season.
Frequently asked questions
Can an H-1B or F-1 visa holder start an LLC?
Yes, they can own one, but only as a passive investor — no day-to-day management, active work, or compensation for labor in the company — otherwise it can be treated as unauthorized employment affecting their status. Consult an immigration attorney before taking any practical step.
Do I need a Social Security number to start a business?
No. You can get an EIN (business tax ID) without an SSN by submitting Form SS-4 by fax or mail, and you can use a registered agent service if you don't have a permanent US address.
What's the practical difference between an LLC and a corporation?
An LLC is administratively simpler and its taxes usually pass through to the owner's personal return. A corporation (especially a C-corp) can face double taxation at the company and shareholder level, but it suits plans to raise significant investment or eventually issue stock.
Is a sole proprietorship easier than an LLC?
Yes procedurally — there's usually no separate formal registration beyond a trade name if needed — but it doesn't separate your personal assets from business debts, meaning unlimited personal liability, unlike an LLC.
Which state should I register my business in?
Most commonly, the state where you actually operate — it's simpler tax- and admin-wise. Some register in states like Delaware for specific legal reasons, but that usually also requires 'foreign qualification' registration in your actual home state, adding cost.
Do I need a special license for my business?
It depends on your activity, state, and city. Use the official SBA tool to find out which licenses apply to your location and business type.
