Tax identification documents and calculator for ITIN and EIN applications

Tax ID - ITIN & EIN

Prepare your tax ID application with guidance on eligibility, documents, and submission.

Not sure which tax ID you need? The right application depends on whether you are filing as an individual or registering a business. We review your situation before preparing the request.

An ITIN (Individual Taxpayer Identification Number) is for people who need a US tax ID and are not eligible for a Social Security Number. An EIN (Employer Identification Number) identifies a business for federal tax purposes. They serve different needs and are not interchangeable.

Ana Claudia reviews the application details and required documents with you, then coordinates preparation and submission. You can discuss the process in English, Portuguese, or Spanish, including when you are applying from abroad.

An ITIN identifies an individual for US tax purposes when they are not eligible for a Social Security Number. An EIN identifies a business. We confirm which application fits your situation.

Yes. Applicants outside the US can apply for an EIN. The submission method depends on the business and responsible party's details. We review the applicable route and required information.

The application uses Form W-7, proof of identity and foreign status, and usually a federal tax return unless an exception applies. The IRS has specific rules for originals and copies certified by the issuing agency. We confirm the list for your case.

Banks commonly request an EIN along with company registration and ownership documents. Requirements and account approval depend on the institution, so confirm its checklist before applying.
