ITIN & CAA Compliance
If you already have an ITIN, or you're about to apply for one, you probably didn't think much about how your agent handled your passport. This article is about exactly that: what an IRS Certifying Acceptance Agent is required to do, which shortcuts genuinely break the rules, and what is at stake if yours took one. The document rules are stricter than most applicants realize, and the consequences are narrower and more specific than they look.
Quick Answer

A Certifying Acceptance Agent is a person or firm that has signed a formal agreement with the IRS to help people apply for ITINs. The role is narrow and specific: review your Form W-7, examine your identity documents, interview you, and certify to the IRS that the documents are genuine.
That certification takes a specific form: the CAA completes a Form W-7 (COA), Certificate of Accuracy, and attaches it to every W-7 they submit. In the IRS's own words, the COA verifies that they reviewed the original documentation, or certified copies from the agency that issued them. Most of what follows in this article turns on that one requirement.
Three requirements set the baseline:
IRS source: irs.gov/individuals/itin-acceptance-agent-program
Both of these turn up in ITIN work. Neither is a gray area, and neither is about which country you're in.
You send a phone photo of your passport. Nobody asks for the original. Nobody asks you to obtain a certified copy from the issuing agency. No original document is ever in anyone's hands. A Certificate of Accuracy gets signed anyway.
That last part is what makes it a problem rather than just sloppiness. The COA states that the agent reviewed original documentation or an issuing-agency certified copy. If no such document ever existed in the agent's possession, the certification isn't accurate — and certifying it is the agent's own act, not yours.
What is not the problem
You can mail your original documents to the CAA (never internationally to the IRS), have them hold the originals during a video interview, and get them back afterward. That meets the requirement. A video interview is expressly permitted, and sending originals to your agent is routine practice.
What matters is whether an original was ever verified. Doing it remotely is fine; skipping it is not.
The second shortcut sits upstream of the documents: manufacturing a U.S. tax purpose that doesn't exist. An ITIN is issued because someone needs a taxpayer ID for a federal tax reason. Where there's no such reason, an agent looking for a sale can invent one — a return that doesn't reflect real income, or dependents the filer isn't entitled to claim.
The fraud patterns that turn up in ITIN work include:
This is the shortcut that can reach you. The document shortcut is your agent's compliance failure; a fabricated tax purpose, or an entitlement you never had, goes to whether you should have received the ITIN in the first place. That distinction shapes the next two sections.
Not sure your reason was ever valid? Eligibility is a separate topic, and we've written it up in detail — who can actually apply for an ITIN
The Acceptance Agent program has published requirements, compliance reviews, and a termination clause. Here is what each one involves.
What's documented:
That last point is the important one: accepting an application you know contains false material information is, by itself, grounds for termination. The agent doesn't need to be prosecuted for the agreement to end.
One requirement tightened on June 1, 2026
Since June 1, 2026, a CAA submitting Form W-7 for a client claiming Exception 1(a) Partnership must include a copy of the portion of the partnership or LLC agreement that displays the partnership's name and EIN, along with the applicant's name and signature. It is a narrow requirement, but it is already in force.
Two things can go wrong, and they are not equally likely. Here they are, in order.
This is the realistic downside, and it's mundane: the Form W-7 is rejected or suspended, the ITIN doesn't issue, the return attached to it is delayed, and you pay someone to put the package together again. The IRS notice for an ITIN application rejection is the CP567.
There's a timing consequence attached. A return filed without a valid taxpayer ID can't be processed normally, so any refund or credit waits until the ID issue is sorted out. That delay, measured in months and re-filing, is usually the real cost of a bad agent.

The IRS can revoke an ITIN it determines was obtained fraudulently.
That turns on the application itself: whether you were entitled to the ITIN, and whether the identity behind it was genuine.
If you're a real person who genuinely can't get an SSN, and you had a genuine U.S. federal tax purpose, the substance of your application was sound. How your agent handled your documents is a compliance problem for your agent. If you aren't sure the substance was sound, that's the part worth having reviewed.
You don't need to be a tax professional to run this check. You only need to remember what happened.
Signs it was handled properly:
Signs worth a second look:
Landing in the right-hand column isn't proof of fraud, and it isn't cause for panic. As the risk tiers above explain, the realistic exposure for most people is a failed application, not a lost ITIN. It is reason enough to have the filing looked at by someone who wasn't involved in it.
If you're physically in the United States, usually not. The IRS lets you apply for free at a Taxpayer Assistance Center: bring your Form W-7, your return if one is required, and your original documents, and the IRS authenticates most supporting documents and returns them at the end of the appointment. No mailing, no third-party fee. Only some centers offer ITIN services, so use the IRS's own list below, and call 844-545-5640 to book — it can take several weeks to get an appointment. Two caveats: the IRS can't authenticate school or medical records for dependents this way, and this route only exists if you can physically get to a center. A CAA is the answer when you're a foreign nonresident outside the U.S. and the alternative is putting your passport in the international post — the IRS's own comparison is that a CAA works in the U.S. or abroad, but fees may vary.

If you're choosing an agent now, seven questions will tell you most of what you need to know. None of them require any tax knowledge.
1. Find them on the IRS list
The IRS publishes its Acceptance Agents by country. Look up the name before you send anything. If a firm claims to be a CAA and isn't on that list, stop there — this is the one check you can do in two minutes, on the IRS's own site, without trusting anybody.
2. Ask what happens to your original document
A compliant answer describes possession: you come in person, or your originals come to the agent and go back to you. An answer where no original or issuing-agency certified copy ever reaches anyone is the shortcut described above — and "just upload a scan, that's all we need" is exactly what it sounds like.
3. Ask about the interview
In person or by video are both fine; the IRS permits video conferencing for the interview. "We don't really do interviews" is not fine. The interview is a requirement, not a formality some agents skip.
4. Ask about the Certificate of Accuracy
A real CAA knows instantly what a Form W-7 (COA) is and will confirm they attach one to every W-7 they submit. Hesitation here is disqualifying — it's the single form that defines the job.
5. Ask them what your U.S. tax purpose is
Then listen for whether they're willing to tell you that you don't have one. An agent who will talk you out of an application you don't need is worth more than one who never has. If the purpose seems to be getting invented on the call to fit you, that's the second shortcut happening in real time.
6. Ask whether you'll still have to mail your passport to the IRS
Mailing your original documents to the IRS ITIN Operation is a legitimate route the IRS publishes, and the IRS says it returns supporting documents within 60 days — if you're applying without an agent, it's a real option. So if an agent's process still ends with your passport in the international post to a U.S. government office, ask what you're paying them for. If you're overseas, avoiding that is the main reason to use a CAA.

7. Ask where their numbers come from
If an agent quotes you a specific penalty or back-tax figure your last agent has supposedly exposed you to, ask which IRS authority says so. How they answer tells you most of what you need to know about them.
Measured steps, in order. None of this requires assuming the worst.
Pick whichever one describes you. If none of them do, you probably don't need us.

You're here about U.S. tax filing generally
ITINs are one piece of a bigger picture. If your question is really about returns, treaty positions, or a filing obligation you're not sure about, start here.
Contact Copper River TaxWe're not going to promise you an approval, a timeline, or that the IRS moves faster for us. Nobody can honestly promise those things, and an agent who does is telling you something useful about themselves. What we will do is tell you if you don't have a valid U.S. tax purpose — in which case there's nothing here for you to buy.
Almost certainly not on that basis alone. Revocation is about whether the ITIN should have been issued to you at all — whether you were entitled to it, and whether the identity behind the application was genuine. That's a different question from whether your agent followed the document-handling rules. If you're a real person with a real U.S. tax purpose who can't get an SSN, your agent's shortcut is their compliance problem. The realistic risk to you is an application that fails, not an existing ITIN being pulled.
That can be perfectly compliant. The rule is that the CAA has the original documents — or certified copies from the issuing agency — in their possession during the interview, and the IRS permits the interview to be conducted by video conference. Originals sent to your agent and returned to you is a normal process, and it's very different from mailing your passport internationally to the IRS. What isn't compliant is nobody ever having an original or an issuing-agency certified copy at all.
We couldn't find evidence of a current enforcement wave, so we're not going to claim there is one. What is documented: the IRS conducts compliance reviews of CAAs — both physical and correspondence — CAAs must cooperate with IRS, TIGTA, and GAO requests for information, and the IRS can terminate an agent's agreement for material non-compliance or for accepting an application knowing material information on it is false. One documentation requirement also tightened on June 1, 2026 for Exception 1(a) Partnership applicants.
The IRS publishes its Acceptance Agents by country, and your agent's name should appear on the list for the country they operate in. You should be able to verify any agent this way — including us — without taking anybody's word for it. If a firm isn't on the list, that's the end of the inquiry.
This is the most common outcome of a badly prepared application, and it's fixable. The CP567 is the IRS's ITIN application rejection notice — read what it actually says, work out whether the problem was the identity documents, the tax purpose, or the attached return, and then re-file a properly documented package. A rejection isn't a permanent bar. The cost is usually time and re-work: while there's no valid taxpayer ID, any refund or credit on the attached return waits.
