Yes, You Can Start a Business

No federal law prevents an undocumented immigrant from owning a business or forming an LLC. Business formation is handled at the state level — and no state requires proof of immigration status to file for an LLC or register a business name.

Millions of ITIN holders run legitimate businesses across the U.S. — as freelancers, contractors, food vendors, cleaners, drivers, construction workers, and more. Formalizing that work as an LLC provides legal protection, better access to banking, and a professional structure for contracts and clients.

ITIN → EIN: the key step

Your ITIN is your personal tax ID. Once you form a business, you'll also need an EIN — your business's tax ID. You use your ITIN to apply for the EIN. After that, the EIN is what you give to banks, clients, and the IRS for all business purposes.


Sole Proprietor vs. LLC — Which to Choose

StructureSetupLiability ProtectionBest For
Sole ProprietorshipNone required — you just start workingNone — personal assets at riskVery small, low-risk work (freelancing, cleaning, etc.)
LLC (Single-Member)File Articles of Organization with the state (~$50–$500 fee)Yes — separates personal and business liabilityMost small businesses; anyone with clients or contracts
LLC (Multi-Member)Same as above, plus an Operating AgreementYesBusinesses with multiple co-owners

For most ITIN holders starting a business, a single-member LLC is the right choice. It costs $50–$500 to form (varies by state), protects your personal assets from business debts, and is taxed the same way as a sole proprietorship — all business income flows through to your personal tax return filed with your ITIN.


Complete Step-by-Step Guide


Getting an EIN Without an SSN

The EIN application process is the most common point of confusion for ITIN business owners. The IRS's online EIN tool requires an SSN — but you can get an EIN by applying by mail or fax using Form SS-4.

On Form SS-4:

Mail to the IRS address listed in the Form SS-4 instructions for your state. Faxing to the IRS is faster — look up the correct fax number for your state in the SS-4 instructions. There is no fee for an EIN.

⚠️ One EIN per responsible party

The IRS limits each responsible party to one EIN per day and generally one per business. Do not apply for multiple EINs — you only need one per LLC. If you form a second business, you can apply for a second EIN at that time.


Business Banking With an ITIN

Once you have an EIN, opening a business bank account is straightforward at banks that serve immigrant communities. Bring:

Credit unions — especially those with a Juntos Avanzamos designation — and community banks are typically the most accommodating for ITIN business banking. Some online banks also accept EIN + ITIN for business accounts.


Frequently Asked Questions

Can an undocumented immigrant start a business or LLC? +
Yes. No federal law prevents undocumented immigrants from owning a business or forming an LLC. States do not verify immigration status during business registration. You can form a sole proprietorship or LLC, get an EIN from the IRS using your ITIN, and operate a legal business.
What is an EIN and do I need one? +
An EIN is your business's federal tax ID number. You need it to open a business bank account, file business taxes, and accept payments professionally. ITIN holders get an EIN by mailing or faxing Form SS-4 to the IRS with their ITIN as the responsible party's ID. It's free and the IRS does not check immigration status.
Can I open a business bank account with an ITIN? +
Yes, with an EIN. Once you have your EIN and LLC formation documents, most credit unions and community banks will open a business account using EIN + ITIN + passport. Juntos Avanzamos credit unions and ITIN-friendly banks are your best starting points.
Does owning a business affect my immigration status? +
Owning a business does not by itself affect your immigration status. Most ITIN owners operate as sole proprietors or LLC members — self-employment, not employment — and report income on their personal tax return with their ITIN. Consult an immigration attorney if you have concerns specific to your situation.
