For a US ITIN application, the IRS generally does not accept a passport copy certified by a notary, including an Australian notary. It wants your original passport, a copy certified by the agency that issued it, or verification by an IRS-authorised acceptance agent. Check the current IRS instructions before you send anything.
An Individual Taxpayer Identification Number is issued by the US Internal Revenue Service to people who have a US tax filing or reporting requirement but are not eligible for a US Social Security number. Australians commonly need one to claim a reduced treaty rate on US income, to file a US tax return, to be included as a spouse or dependent on a US return, or to deal with US rental property, royalties, gambling winnings or certain investments.
The application is made on Form W-7, usually attached to a US tax return or accompanied by evidence of why the ITIN is needed. The IRS must be satisfied of your identity and your foreign status, and a passport is the one document that proves both. That is where the certified copy question comes in. Our guide to US documents from Australia covers other US paperwork.
The IRS sets its own identity rules for Form W-7, and for many years its instructions have said that copies of identity documents must be certified by the agency that issued the original, and that notarised copies are not acceptable. The reason is practical: the IRS cannot verify notaries in every country, but it can rely on the issuing government's certification, or on its own authorised acceptance agents.
That means a copy certified by an Australian notary, however carefully made, is likely to be rejected, and the application delayed. This is one of the few situations where a notary is genuinely the wrong answer for a document going overseas. Rules can change, so read the IRS's current Form W-7 instructions rather than relying on older advice, including advice that says a notarised copy will do.
There are generally three routes, each with trade-offs.
Some applicants can also apply in person at IRS offices or through other IRS-approved channels, but those are generally in the United States. Check the current options in the IRS's W-7 guidance.
| Route | Keeps your passport with you? | Watch out for |
|---|---|---|
| Original passport by mail | No, for the processing time | Travel plans and postal risk |
| Copy certified by the Australian Passport Office | Yes | Whether and how it offers this service |
| Certifying Acceptance Agent | Yes | Finding one who serves your location |
| Copy certified by an Australian notary | Yes | Generally not accepted for Form W-7 |
| Copy certified by a JP | Yes | Not accepted for Form W-7 |
A Certifying Acceptance Agent, or CAA, is a person or organisation, often an accounting or tax firm, that has an agreement with the IRS to help people apply for ITINs. A CAA can review your identity documents, verify them, and send certified copies to the IRS, so you keep your original passport. CAAs usually charge for the service, and many also prepare the tax return that goes with the application.
The IRS publishes a directory of acceptance agents, including some outside the United States. If there is no CAA near you in Australia, some may be able to act for you by other means that the IRS permits; ask them. A CAA's certification is different from a notary's: it is recognised by the IRS for this specific purpose because of the CAA's agreement with the IRS.
Generally not for the passport copy itself, because the IRS's own rules decide what it accepts, and an apostille would not turn a notarised copy into an acceptable one. The United States and Australia are both Apostille Convention parties, and apostilles are used for many other US purposes, such as documents for US courts, some state agencies and some companies. For the ITIN, follow the W-7 instructions rather than adding steps the IRS does not ask for.
If you do not use a passport, the IRS generally requires a combination of other identity documents, one of which must show a photograph and another your foreign status, subject to the same rules on certified copies. Supporting documents explaining why you need an ITIN, such as a letter from a US payer or a completed tax return, usually go with the application. Dependents may need additional documents. Read the current instructions for your situation, because the rules for dependents and for particular exceptions are detailed.
A notary is still useful for many US documents, just not for the W-7 passport copy. US banks, brokers, estates, courts and state agencies often ask for signatures to be notarised, or for documents to be notarised and apostilled. A US transfer agent may want a Medallion signature guarantee, which a notary cannot provide. Our guides to the Medallion signature guarantee and sending Australian documents to the USA cover those.
The most common is sending a notarised or JP-certified passport copy, which leads to a rejection letter weeks later and a fresh application. Others include a name on Form W-7 that does not match the passport exactly, a missing or unclear reason for needing the ITIN, a missing tax return where one is required, and an expired passport. Each of these delays the application, and meanwhile a US payer may keep withholding tax at the full rate.
Before sending, read the instructions once more against your application, and if you use a Certifying Acceptance Agent, ask them to check the whole package, not just the passport. It is also worth keeping a record of when and how you sent everything, in case you need to follow up with the IRS about a delay.
Here is an illustration, not a real case. Grace lives in Hobart and earns royalties from a US publisher, which withholds tax at the full rate until she provides a US tax number. She needs an ITIN.
A friend suggests a notarised copy of her passport, but Grace reads the Form W-7 instructions and sees that notarised copies are not accepted. Because she has an overseas trip planned and cannot send her passport away, she contacts a Certifying Acceptance Agent listed by the IRS, who verifies her passport, certifies a copy and submits the application with the royalty letter. She keeps her passport throughout.
For a US ITIN, the IRS generally does not accept passport copies certified by a notary, Australian or otherwise. Send your original passport, a copy certified by the agency that issued it, or use an IRS Certifying Acceptance Agent. An apostille does not change that. Read the current Form W-7 instructions first, and keep notaries for the many other US documents where they are the right answer.

Generally not in a way the IRS accepts. The IRS's Form W-7 identity rules have long excluded notarised copies. Use your original passport, a copy certified by the issuing agency, or a Certifying Acceptance Agent. Check the current W-7 instructions.

The Australian Passport Office, part of DFAT. Ask it directly whether and how it provides certified copies of a passport for an ITIN application, because the IRS generally accepts copies certified by the issuing agency.
Yes, and the IRS returns original documents after processing. But you will be without your passport for some time and there is postal risk. If you need to travel, a Certifying Acceptance Agent or issuing agency copy is safer.
Generally no. The IRS's own rules decide which copies it accepts, and an apostille does not change a notarised copy into an issuing agency copy. Follow the Form W-7 instructions rather than adding steps.
No. A JP-certified copy is not accepted for Form W-7, and JP certifications are generally not accepted by overseas bodies. Use one of the routes the IRS accepts.

Yes. Many US banks, brokers, estates, courts and state agencies want signatures notarised, sometimes with an apostille. A notary is just not the right route for the Form W-7 passport copy.
