How to use your ITIN for US banking, credit cards and LLC payments
Put your ITIN to use for LLC banking, credit cards and payments. Exentax helps assess Chase, Bank of America and Square for your business and residence.
An LLC and an ITIN can give you more options to explore in the United States, from branch banking to credit cards and certain payment services. The practical question is which application needs which information, and which product fits the way you actually operate.
At Exentax, we help owners work through that decision. Our support includes traditional banks such as Chase and Bank of America, alongside payment processors and international banking arrangements. This guide focuses on the next step: you own an LLC, have an ITIN or are applying for one, and want to put it to a useful purpose.
Where an ITIN fits into a financial application
The IRS issues ITINs for federal tax purposes to individuals who need a taxpayer number and are not eligible for an SSN.
Some financial providers accept that number when identifying an applicant. That can make it possible to consider an application requiring a US identifier for the individual. Product eligibility, application channel and accepted residence still need to be checked: accepting ITINs is not the same as accepting every international applicant.
Start with the job you need the product to do. Are you looking for a card for recurring expenses, access to a bank branch, or a way to take customer payments? Each has a different application. A clear purpose is more useful than obtaining a number and expecting every financial service to become available at once.
Completing an application: your ITIN and your LLC's EIN
A business application contains information about both the company and the people behind it. Read the field label before entering a number. “Business tax ID”, “Applicant” and “Owner” refer to different parts of the application.
| Application field | What to check | Supporting record |
|---|---|---|
| Legal business name | The LLC's registered name, not just its trading brand | Formation document |
| EIN / Business tax ID | The business identifier requested | EIN confirmation |
| Applicant SSN / ITIN | That individual's identifier, where ITIN is accepted | ITIN assignment notice |
| Role and ownership | Who applies, who signs and their ownership percentage | Current company records |
Use this as a preparation guide, not a replacement for the provider's instructions. A tax form may have different rules from a commercial application. Follow the instructions for the particular form in front of you.
For a multi-member LLC, one owner's ITIN does not identify the other members. Establish who is applying, who has signing authority and, for credit where applicable, who would give a guarantee. If the online form only offers an SSN field, ask the provider which official application route supports ITINs. Do not substitute a different identifier simply to get past the field.
Keep the ITIN notice and use it in the right application
Keep your CP565 assignment notice with your personal records. The ITIN belongs to the individual: owning interests in two LLCs does not mean applying for a new ITIN for each company. Keep company identifiers separately; the IRS explains the EIN's role in identifying business entities.
Before sharing the number with a provider, check the legal name and digits against the notice. If you already have an application in progress, ask how to add the information to that reference. Keeping the correspondence together lets the reviewer see what has changed instead of reconstructing several separate applications.
Also distinguish providing the number from providing a copy of the notice. Not every application requests both. Use the secure channel specified by the institution and provide the documents it needs for that application. In a multi-member LLC, each participant supplies their own personal details when required.
Keep a simple record of the product, submission date, application reference and next expected response. “Documents received”, “account opened” and “credit approved” are different milestones. Knowing which stage you have reached makes follow-up more useful. Exentax can help you prepare the response and keep the next step clear.
Preparing for a Chase branch appointment
Chase's LLC account-opening guidance distinguishes member-managed and manager-managed companies, including who needs to attend. That matters when arranging a visit.
We start before the appointment: understand the structure, establish who can act for it, and check what the branch needs for the particular case. We also help explain how the account will be used. Receiving service revenue, paying suppliers and holding working capital are different requirements, even within the same business.
A useful preparation call should produce a clear document list, identify everyone who must attend and leave no ambiguity about the next step. If your LLC already has an operating account, Chase can be considered as an additional banking relationship. Assessing branch banking does not require treating every existing account as unsuitable.
Our guide to US banks for LLC owners covers the wider comparison. Here, the point is to use an ITIN in the right application, rather than treat it as a replacement for the bank's review.
Bank of America: confirm the route before applying
Bank of America's published LLC application requirements specify US-resident applicants. They do not describe a universal online route for overseas owners.
Exentax can still help you assess Bank of America. We first need to establish with the bank which route is available for your residence, ownership structure and business activity. Support means preparing and following through on an appropriate application, not assuming an appointment overrides product eligibility.
Before proceeding, identify the exact account, the application channel confirmed by the bank, and the personal documentation for each participant. An answer about a personal account should not be carried over to the LLC's account. Nor should approval for a deposit account be treated as approval for a credit card.
Credit cards with an ITIN: choose the application, not just the number
Chase's credit card application guide includes SSNs and ITINs among identifiers. This is general guidance, not approval for a specific card.
Begin with the expenses you want the card to cover. Advertising, travel, subscriptions and supplier purchases follow different schedules. Decide whether you need to finance a payment gap or simply organise expenses and pay the monthly balance in full. A headline limit or welcome offer should not make that decision for you.
Review the annual fee, applicable interest, statement and payment dates, currency charges, any personal guarantee and who owes the balance. A business card and an owner's personal card are not interchangeable. See our explanation of personal versus business credit in the US for the implications of that choice.
An ITIN also does not create a record of repayments by itself. If building credit is part of your plan, check how the relationship is recorded and which information the provider reports. Our guide to US financial history explains that distinction without confusing bank statements with credit reports.
Using an ITIN for Square's business onboarding
Square accepts an SSN or ITIN for personal verification and requires a US home mailing address. The business EIN is requested separately.
Having an LLC and an ITIN therefore starts the assessment; it does not complete the application. At Exentax, we review whether Square fits the business activity and the applicant's actual circumstances. A registered agent's address should not automatically be entered as the person's home address.
Keep this separate from choosing a credit card. Square concerns taking customer payments; a card concerns paying for, or financing, expenses. Both may support the same business, but they are different services with different applications. An ITIN should be obtained for its proper purpose, then used where the selected provider accepts it.
One LLC, two different applications
Imagine an LLC selling services and planning to organise USD 2,000 of monthly recurring expenses. Its owner already has an ITIN. The first objective is an expense card; the second is assessing Square for an in-person sales activity. This is a planning example, not a client result or an approval.
For the card, we would examine the applicant, ability to repay and product terms. For Square, we would examine the activity, business onboarding and published personal requirements. One application may progress while the other calls for a different solution.
The LLC retains a common legal identity, ownership structure and business purpose. The chosen tool changes. This approach lets several providers play useful roles without expecting a single account to cover banking, payments, credit and currency management equally well.
A practical application plan with Exentax
- Set the objective. Branch banking, a card, financing or customer payments: explain what your current arrangements are missing.
- Identify the person and the LLC. Establish residence, business activity, ownership, EIN and whether the ITIN is assigned or being obtained.
- Confirm the product and channel. Check the provider's applicable criteria before submitting the application.
- Review the application details. Align names, addresses, signatories and supporting records, and keep the application reference.
- Assess the response and terms. Answer further questions within that application. Review any offer's cost and usefulness before accepting it.
If you still need the number, our W-7 and CAA guide to obtaining an ITIN explains that process. If you already have one, we work from your existing position rather than starting again or requesting another number. For the records themselves, use our financial application preparation guide.
Questions about using an ITIN for LLC banking and credit
Can I apply for a credit card with an ITIN?
Yes, some issuers and products accept it. Confirm the particular product and assess residence, identity, ability to repay and application terms.
Can Exentax help with traditional banks?
Yes. We help assess Chase and Bank of America, prepare documentation and coordinate next steps. The bank determines eligibility and any required in-person checks.
Does my ITIN replace my LLC's EIN?
They identify different subjects. Follow each application field's instructions and distinguish the company's information from the applicant's personal details.
Does opening an account mean I will receive credit?
No. Deposit account opening and lending are separate decisions. Evaluate each product against its purpose and your financial circumstances.
Should I apply for several cards at once?
We recommend choosing products that address a genuine need and reviewing their terms first. Batch applications are not a substitute for a financing plan.
