ITIN Application & Renewal Assistance

What is an ITIN and why does it matter?

An Individual Taxpayer Identification Number (ITIN) is a tax processing number the IRS issues to people who must file or be included on a U.S. tax return but are not eligible for a Social Security number. It is for tax reporting: it does not change immigration status or authorize work, and it is not an Employer Identification Number (EIN) for a business.

Applying means completing Form W-7 and sending supporting documents to the IRS, which decides each application. The application is generally submitted with a federal tax return, with some exceptions the IRS lists, and the IRS publishes which identity and foreign-status documents it accepts and how original or certified documents are to be submitted — these details can change. OG helps you prepare Form W-7, reviews your documents with you at our Paterson, NJ office or by appointment in the Spring, TX area, and explains how the application is submitted. We cannot promise approval or a timeline. If a tax return is part of your filing, see our tax preparation service.

What our CAA status means: OG Multiservices LLC is an IRS-authorized Certifying Acceptance Agent (CAA). A CAA can review certain original identity and foreign-status documents and certify copies for the IRS, so those originals do not always have to be mailed with the application. This applies only to the documents and applicants the IRS allows — for example, for dependents a CAA can certify only passports and birth certificates — and other documents must still be sent to the IRS. Being a CAA does not make OG part of the IRS: the IRS alone decides each application, and it publishes its list of Acceptance Agents on its website. Preparing Form W-7 and certifying documents are separate steps, and we explain which of them apply to you before anything is sent.

Frequently asked questions

Do I need to mail my passport to the IRS?
Not always. As an IRS-authorized Certifying Acceptance Agent, OG can review an original passport and certify a copy for the application, so the original passport does not always have to be mailed to the IRS. What applies depends on the applicant and the document — for dependents a CAA can certify only passports and birth certificates, and other documents still go to the IRS — and the IRS decides each application. We go over your documents with you before anything is sent.
How long does it take to get an ITIN?
Processing time is set by the IRS and varies, so we cannot promise a timeline. We tell you what the IRS currently publishes once we review your application.
Can I apply for an ITIN without filing a tax return?
In most cases an ITIN application must be submitted together with a tax return, though there are some exceptions. We'll help confirm what applies to you.
What is the difference between an ITIN, a Social Security number and an EIN?
A Social Security number is issued by the Social Security Administration. An ITIN is a tax processing number issued by the IRS to people who need one for a tax return but are not eligible for a Social Security number. An EIN identifies a business. They are not interchangeable, and an ITIN does not change immigration status.
Which documents are needed for an ITIN application?
The IRS lists the accepted identity and foreign-status documents in the Form W-7 instructions, and the list can change. A valid passport is commonly used because it can serve as both. We review the documents you have and tell you what looks missing before the application is prepared.
Is OG an IRS Certifying Acceptance Agent?
Yes. OG Multiservices LLC is an IRS-authorized Certifying Acceptance Agent (CAA), and the IRS's public list of Acceptance Agents for New Jersey includes OG. A CAA can review certain original documents and certify copies for an ITIN application, within the limits the IRS sets. OG is not the IRS or a government agency, does not issue ITINs and cannot guarantee approval.
