Florida is one of the most popular states in the country for foreign-owned businesses. Naples draws Latin American investors buying into real estate LLCs. Fort Lauderdale hosts international logistics companies, yacht brokers, and import-export operations with owners who have never set foot in a Social Security office. The business directories of both cities are packed with companies whose registered agents are the only people in the building with a U.S. ID.
That creates a practical problem fast: U.S. banks want a tax identification number. The IRS wants to know who you are. And the two systems — one for individuals, one for entities — operate on completely different tracks. Getting them confused costs time, money, and sometimes the business itself. Here is a clear-eyed breakdown of what each number does, who needs what, and how non-resident owners actually get a bank account open.
1. Understand What an ITIN Actually Is (and Isn’t)
An Individual Taxpayer Identification Number (ITIN) is a nine-digit number issued by the IRS specifically for people who have a U.S. tax filing obligation but are not eligible for a Social Security Number. It always starts with the digit 9 — for example, 9XX-XX-XXXX. It is not a work permit, not a green card path, and not proof of legal immigration status. It is purely a tax processing tool.
Foreign nationals who own a share of a U.S. LLC or corporation and receive income or distributions from it typically need an ITIN to file Form 1040-NR (the non-resident alien income tax return) or to be listed on partnership returns. Without one, the IRS has no way to match withholding payments to an individual. You apply using IRS Form W-7, and you need original identity documents — usually a passport — or certified copies. Processing currently takes seven to eleven weeks during peak season, so apply before you need it, not the week your accountant calls.
2. The EIN Is for Your Business, Not for You
An Employer Identification Number is the business equivalent of a Social Security Number. Every LLC, corporation, or partnership that operates in the United States needs one — for filing taxes, opening a business bank account, hiring employees, and in many cases just getting a merchant processing account. The good news: a non-resident alien can get an EIN for their U.S. entity even without an ITIN. These are parallel systems, not sequential ones.
The fastest route for non-residents is to call the IRS Business & Specialty Tax Line at 1-800-829-4933 and request an EIN by phone. You’ll need your company’s legal name, the state of formation, the entity type, and the name and taxpayer ID of the “responsible party” — which, for a foreign owner, may be their ITIN if they have one, or their foreign tax identification number. If you cannot call from outside the U.S., you can fax Form SS-4 to the IRS at the number listed on the form; expect a four-to-five business day turnaround. Online EIN applications are available only to applicants with a U.S. SSN or ITIN, so foreign owners often get stuck there — skip the online tool entirely.
3. Why Banks Ask for Both (and What They’re Really Checking)
When a Fort Lauderdale LLC walks into a bank branch to open a business account, the bank is running two separate compliance checks. The first is entity-level: they want the EIN, the articles of organization, and often an operating agreement showing who controls the company. The second is individual-level: under FinCEN’s Customer Due Diligence rules, banks are required to identify any individual who owns 25% or more of the entity and any single person who controls the business. For non-resident owners, that means presenting a passport and, in many cases, providing an ITIN or a foreign tax ID.
A common mistake is assuming the EIN alone is enough to open an account. It isn’t. The bank is not just verifying the business exists — it is satisfying Bank Secrecy Act obligations around beneficial ownership. Foreign nationals who don’t yet have an ITIN should be prepared to show a valid passport, a foreign tax ID number from their home country, and proof of address (a utility bill or bank statement from abroad is usually acceptable). Some banks, particularly larger regional ones in South Florida with international banking divisions, have specific non-resident programs that streamline this process considerably.
4. Choosing the Right Bank Is Half the Battle
Not all U.S. banks are equally equipped — or willing — to onboard non-resident business owners. The major national banks like Chase, Bank of America, and Wells Fargo technically allow non-resident accounts, but branch-level staff often lack training in the process and may incorrectly tell you it’s impossible. The branches in Miami, Fort Lauderdale, and Naples that serve international clientele regularly are a different story: they have compliance officers who handle these accounts weekly.
A better starting point for many foreign owners is a community bank or credit union with a documented international banking program, or one of the fintech-based business banking platforms that have emerged specifically for this gap. Mercury, Relay, and similar platforms have onboarded non-resident LLCs with EINs and foreign passports, though their own policies shift frequently — always verify current requirements directly. For companies with significant transaction volume, HSBC’s U.S. international banking division and Citibank’s global banking units are genuinely set up for this use case. The right institution saves weeks of frustration; the wrong one just sends you in circles.
5. The ITIN Application Process Has Real Traps
Applying for an ITIN sounds simple — fill out Form W-7, attach your passport, mail it in. In practice, the IRS rejects a significant percentage of first-time applications for avoidable reasons. The most common: the applicant fails to include a completed U.S. tax return with the application. The ITIN is not issued in a vacuum; it must be tied to a tax filing purpose. For a new business owner who hasn’t yet filed a U.S. return, this creates a chicken-and-egg problem.
There are two legitimate workarounds. First, certain exceptions allow an ITIN application without a tax return — Exception 1 covers third-party withholding situations, and Exception 4 covers mortgage interest scenarios, for instance. Second, you can use a Certified Acceptance Agent (CAA), which is a person or organization authorized by the IRS to verify identity documents and submit W-7 applications. CAAs are especially useful for foreign applicants who cannot mail their original passport to the IRS and wait weeks without it. Many tax attorneys and CPAs in the Naples and Fort Lauderdale business communities are designated CAAs — it’s worth asking before you hire anyone to help with this process. The IRS maintains a searchable directory of certified acceptance agents by state and country.
6. Timing Everything Correctly Matters More Than Most Guides Admit
The practical sequence for a non-resident forming a Florida business looks like this: form the entity first (Florida’s Division of Corporations processes most filings within a few business days), then apply for the EIN immediately after, then open the bank account using the EIN and passport while the ITIN application is pending. Most banks will accept a pending ITIN status as long as the application has been submitted and the applicant can show documentation. Waiting to get the ITIN before doing anything else is the single most common mistake foreign owners make — it delays business operations by two to three months for no good reason.
Tax year timing also matters. If you form a company in November and your ITIN isn’t issued until March, you may have a filing gap that requires an extension. File Form 4868 for an automatic six-month extension if needed, and make sure your accountant knows the ITIN application date so the return can be linked properly once the number arrives.
Foreign ownership of U.S. companies is not a loophole or a workaround — it’s a normal feature of American commerce, especially in Florida. The bureaucratic friction around ITINs, EINs, and non-resident banking is real, but it’s navigable with the right sequence, the right bank, and a tax professional who has actually done this before rather than one who’s figuring it out alongside you. Get those three things right and the paperwork becomes background noise instead of a barrier.
