What is the Automatic Exchange of Information (AEOI)?

AEOI is the exchange of financial account information between Tax Authorities in relevant countries. The law requires this information to be collected by Financial Institutions around the world for reporting to Tax Authorities.

AEOI is made up of two information sharing frameworks:

Under the AEOI, all Financial Institutions (including ANZ) must identify accounts held by customers who are foreign tax residents or entities connected to foreign tax residents. Financial Institutions must report these to the relevant Tax Authority who will then automatically exchange the account information with the relevant foreign Tax Authority(ies).

Governments (in countries committed to the AEOI) have enacted domestic laws to require Financial Institutions to collect and report this information and have entered into international agreements to exchange the information with other Governments.

What does this mean for customers?

This means customers will be asked questions about their Tax Residency when they open a financial account with a Financial Institution (and in some other scenarios).

Existing Individual/Entity Customers:

If you have an existing account, ANZ may contact you to confirm your country(ies) of tax residence and request additional information, forms and/or documents. This is to establish whether you have accounts that need to be reported under the FATCA or CRS laws. We may also contact you if information indicates that you could be a foreign tax resident.

New Individual Customers:

If you open a new account, the laws in certain countries may require ANZ to ask you to provide various information such as your country(ies) of tax residence(s), tax identification number(s),  providing certifications, forms and/or documentation.

If you are a foreign tax resident, you need to provide your taxpayer identification number (TIN) or equivalent number used to identify you to the Tax Authority in the foreign country. If you don’t provide a TIN, you will be asked to provide a reason for not doing so.

New Entity Customers: (such as companies, trusts, partnerships, associations etc.)

If you  open a new account on behalf of a legal entity or arrangement (such as a trust or partnership), the laws in certain countries may require ANZ to ask you to provide various  information, certifications, forms and/or documents (within certain timeframes) about:

These requirements ensure all Financial Institutions comply with their obligations under the FATCA and CRS laws and guidance.

What do I need to do?

It is important that you respond if ANZ contacts you requesting information. If you don’t respond, the law may require ANZ  to treat you as if you are a tax resident in a foreign country and report you to the relevant tax authority(ies) (even though you may not be tax resident in a foreign country).  If you intend to open a new account and do not provide the relevant details, ANZ may not be allowed (by law) to open the account for you.

You should respond truthfully and seek advice from an independent tax agent or advisor where required when you state your tax residence(s) or provide other information to ANZ. Penalties may apply (under local and other laws) if you provide false or misleading information.

What happens with my account information?

If you are a foreign tax resident (under the AEOI laws), your identity details, account balance and other information will be provided to the relevant Tax Authority(ies). The Tax Authority(ies) also receives your information if you have not responded to requests for further information as a result of being identified as a possible foreign tax resident. The Tax Authority then exchanges the information with the Tax Authority in the country(ies) of your tax residence(s).

All information reported under these laws is handled in the strictest confidence by the Tax Authorities and is protected by national laws, administrative practices, and binding international treaties. This is the same way that all taxpayer information is generally handled.


This information is to help you understand your obligations under the AEOI laws. It does not constitute any form of advice, has not taken into account your personal circumstances and is general in nature. If you have questions about your tax residence status, you should contact your relevant tax authority (in your country of residence), as applicable, or seek advice from an independent tax agent or advisor to ensure your personal circumstances are taken into account.
