Get your ITIN with Form W-7 and CAA certification

without mailing your original passport to the IRS

We review your circumstances, prepare the documents and follow the application with the IRS. A team that advises you and handles the work with you.

Your personal tax number, prepared for what you need

An ITIN identifies people who need a US federal tax number but neither have nor qualify for an SSN. We review the tax purpose and supporting return or exception before preparing Form W-7.

If you own an LLC, we distinguish the company's EIN from your personal identification. We also examine requests from banks, brokers or payers so you understand where an ITIN belongs and which documents each application needs.

Exentax coordinates CAA verification without sending your original passport to the IRS. You receive preparation, follow-up and guidance on using the number when the assignment letter arrives.

Questions about your ITIN application

How long does the IRS take to issue the ITIN?

The IRS determines the final timeline, which can vary with workload, tax purpose and application review. Exentax prepares the records, coordinates passport authentication with the CAA where applicable and follows the application through the process.

Do I need to travel to the United States to get it?

You do not need to visit an IRS office. Exentax organizes CAA verification without mailing your original passport there and explains the identity checks required.

Can you help with Chase and Bank of America?

Yes. We prepare the application and LLC documents with you, establish who needs to sign and plan the branch requirements. Chase accepts ITINs in certain circumstances; for Bank of America, we first confirm residence, business operations and the appropriate application route.

Can I use my ITIN to activate Square?

Square US accepts an SSN or ITIN to identify the applicant and requires a US home mailing address. Exentax checks your eligibility and coordinates your personal details with the LLC's EIN and documents.

Can you help me apply for cards and access credit?

Yes. We assess suitable cards and financing, distinguish personal from business credit and help prepare the application. The ITIN provides identification; the lender also reviews residence, income and credit history when deciding approval and the credit limit.

Does the ITIN improve an existing LLC structure?

Yes, where the owner needs personal tax identification for a return or a particular procedure. We establish the purpose and coordinate the ITIN with the LLC's EIN and documents, keeping personal and company numbers separate.
