Who this is for

This service is built for these situations

You have a U.S. tax return to file

Rental income, a K-1, a refund of tax withheld — and you can’t get a Social Security number.

You want to claim a tax treaty benefit

Some treaty claims need an ITIN, often under one of the exceptions to the tax-return rule.

You don’t want to post your passport abroad

Mailing originals to the IRS means weeks without your passport. A CAA certifies a copy instead.

Your spouse or children need ITINs too

Family members can be added for $99 each, with the documents each person needs.

A previous W-7 was rejected

A CP567 notice gives the reason. We fix the documents and file again correctly.

Your ITIN expired or is about to

Renewal uses the same Form W-7. We handle it with the return it needs.

Why this is hard alone

Getting an ITIN from outside the U.S. is full of small traps

The IRS rejects a large share of ITIN applications, and most rejections and long delays come from a handful of avoidable mistakes: the wrong documents, a missing tax return or exception proof, or originals lost in the mail.

Common pitfalls

What usually goes wrong when filing alone

  • Mailing your original passport to the IRS and waiting weeks for it to come back.
  • Picking the wrong W-7 reason box, or none, so the IRS can’t process the application.
  • Sending a W-7 without the tax return or exception documents it must come with.
  • Notarized copies — the IRS doesn’t accept them, and the application is rejected.
  • No one to follow up with once the IRS window has passed.

Our approach

How we prevent each of those problems

  • Our Certifying Acceptance Agent examines your original passport on a video call and certifies a copy.
  • The correct W-7 reason and exception chosen for your situation before anything is filed.
  • Tax return or exception documents checked and filed together with the W-7, as the IRS requires.
  • Tracked courier filing to the IRS ITIN Operation in Austin, Texas.
  • Status updates throughout, and follow-up with the IRS once its window has passed (Priority and Complete).
Our approach

What we actually do for you

  1. Eligibility check

    A short intake confirms you need an ITIN at all, which W-7 reason applies, and whether you file with a tax return or under an exception. If you don’t need an ITIN, we tell you.

  2. Preparation & CAA verification

    We prepare your W-7 for you to review and sign, examine your original passport live on a recorded video call (or in person), and certify a copy with a Certificate of Accuracy.

  3. Filing & tracking

    We file the complete application with the IRS by tracked courier, keep you updated through the IRS wait, and tell you as soon as your CP565 assignment notice arrives.

IRS-published details

Three ways a Form W-7 reaches the IRS

Every ITIN application needs the W-7, proof of identity and foreign status, and usually a tax return. These are the routes the IRS lists for getting your documents to it. You can use any of them yourself — the ITIN is free.

IRS ITIN application routes
Certifying Acceptance Agent (CAA)An IRS-authorized agent reviews your original passport (in person or on a video interview) and certifies a copyAnywhere in the worldOriginal passport is not mailed to the IRS
Mail to the IRSInternal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342Anywhere in the worldYou mail originals or copies certified by the issuing agency; originals are returned by mail
IRS Taxpayer Assistance CenterIn-person appointment at a designated IRS office (844-545-5640)Inside the U.S. onlyDocuments reviewed and returned at the appointment
  • Processing time. The IRS says to allow 7 weeks for an ITIN decision, or 9–11 weeks if you apply during peak season (January 15 – April 30) or from overseas. Nobody — no agent and no paid service — can make the IRS process an ITIN faster.
  • Certified copies only. Copies must be certified by the agency that issued the document. Notarized copies are not accepted.
  • A return, or an exception. Form W-7 must be attached to a valid federal income tax return unless you qualify for one of the exceptions listed in the W-7 instructions.

Why the route matters: Applications filed through a Certifying Acceptance Agent were rejected 12.3% of the time, against 27.3% when originals were mailed to the IRS and 18.4% through IRS offices (National Taxpayer Advocate, CY2023 to September 2024).

Realistic timeline

What to expect, week by week

Two clocks apply to every ITIN. Ours: we prepare and certify your application within 1–3 business days of receiving your documents and completing the video verification. The IRS’s: it says to allow 7 weeks, or 9–11 weeks from January 15 to April 30 or when you apply from abroad — and nobody can speed that up. We track your application through the IRS wait, follow up once the IRS window has passed, and tell you as soon as your ITIN is assigned.

  1. Day 1 · Intake

    You answer a few questions and upload your passport. We confirm the W-7 reason and the package that fits.

  2. Your chosen time · Video verification

    A short recorded call where our CAA examines your original passport and confirms your details.

  3. 1–3 business days · W-7 prepared

    We prepare the W-7 and certified copies, and you review and sign. This is our clock, not the IRS’s.

  4. On your approval · Filing

    The application, with your return or exception documents, goes to the IRS by tracked courier.

  5. IRS processing · 7 weeks (9–11 weeks from January 15 to April 30 or from abroad)

    Nobody — no agent and no paid service — can make the IRS process an ITIN faster. We track the application and follow up once the IRS window has passed.

  6. Assignment · CP565

    The IRS mails a CP565 notice with your ITIN. We let you know as soon as we hear.

Frequently asked questions

Common questions from non-U.S. applicants

If your question isn't here, contact us — we'll answer honestly, even if the answer is 'this isn't a fit for our service.'

What’s included in the service?

An eligibility check, Form W-7 preparation, verification of your original passport by our Certifying Acceptance Agent, a certified copy and Certificate of Accuracy, filing with the IRS by tracked courier, and status updates until your ITIN is assigned. Higher packages add IRS follow-up, notice handling and the tax return itself.

How much does it cost?

Three packages: ITIN Essential ($179) if you already have your return or exception documents, ITIN Priority ($249) with exception paperwork, IRS follow-up and notice handling, and ITIN Complete ($449) which adds the federal tax return the W-7 is attached to. Each extra spouse or dependent is $99. The IRS charges nothing for an ITIN.

How long until I get my ITIN?

Two clocks. Ours: we prepare and certify your application within 1–3 business days of receiving your documents and completing the video verification. The IRS’s: The IRS says to allow 7 weeks for an ITIN decision, or 9–11 weeks if you apply during peak season (January 15 – April 30) or from overseas. Nobody — no agent and no paid service — can make the IRS process an ITIN faster.

Do I have to send my original passport anywhere?

No. You don’t mail your original passport to the IRS. Our Certifying Acceptance Agent examines the original on a recorded video call (or in person) and certifies a copy, which is what goes to the IRS.

Do I need a U.S. tax return to apply?

Usually, yes. Form W-7 must be attached to a valid federal income tax return unless you qualify for one of the exceptions listed in the W-7 instructions. Exceptions 1–5 cover third-party withholding on passive income (including partnership income and bank interest), tax treaty benefits, mortgage interest reporting, dispositions of U.S. real property (FIRPTA), and TD 9363 reporting obligations. We check which applies to you before you pay for anything you don’t need.

Can you guarantee my ITIN?

No one can. The IRS decides every application. What we can do is file a complete, correctly documented application, and the Priority and Complete packages include one free resubmission if the IRS rejects it.

Will an ITIN let me work in the U.S.?

An ITIN does not authorize work in the U.S., does not change immigration status and does not by itself make you eligible for Social Security benefits.
