ATO Certificate of Residency or a Notary?

Usually the ATO, not a notary. When a foreign tax authority, bank or fund asks for proof that you are an Australian tax resident, for example to apply a tax treaty rate, it generally wants a certificate of residency issued by the Australian Taxation Office. A notary cannot certify your tax residency.

Key takeaways

• Proof of Australian tax residency comes from the ATO, usually as a certificate of residency. A notary cannot issue it.
• It is commonly used to claim tax treaty benefits, such as reduced withholding tax on foreign dividends, interest, royalties or pensions.
• Some foreign authorities have their own residency forms; whether the ATO will complete one is the ATO's decision.
• If the foreign body wants the ATO certificate authenticated, DFAT can generally apostille ATO documents directly, without a notary.
• A notary is useful for certified copies of the certificate, or for declarations on foreign forms that must be witnessed.

What is an ATO certificate of residency?

A certificate of residency is a document from the Australian Taxation Office confirming that a person or entity is a resident of Australia for tax purposes, usually for a stated period. Foreign tax authorities and payers use it to decide whether to apply the reduced rates or exemptions available under a tax treaty between Australia and their country, rather than their standard rate for non-residents.

Individuals, companies, trusts and super funds can all need one, for example to receive foreign dividends, interest or royalties at a treaty rate, to claim a foreign pension without double taxation, or to satisfy a foreign bank's tax forms. The ATO decides whether you qualify and what the certificate says. Applications are usually made directly to the ATO, often with help from a registered tax agent, and the ATO's own website explains the current process and forms.

Why can't a notary do this?

Tax residency is a legal status determined under Australian tax law, and only the ATO can confirm it officially. A notary can witness your signature on a declaration saying you believe you are an Australian resident, or certify a copy of a document, but neither of those is evidence of residency that a foreign tax authority will rely on. The foreign body wants the Australian government's confirmation, not your own statement witnessed by a lawyer.

Paying a notary to notarise a self-declaration of residency, when the foreign body wanted an ATO certificate, is a common and avoidable mistake. Read the foreign body's instructions carefully: phrases like "certificate issued by your tax authority" or "certified by the competent authority of your country of residence" mean the ATO.

What about a foreign country's own residency form?

Some foreign tax authorities have their own form for claiming treaty benefits, with a section to be completed or stamped by the tax authority of your country of residence. If you receive one, the question is whether the ATO will complete that section, or will instead issue its own certificate for you to attach. That is the ATO's decision, and its practice can differ by country and form.

Before sending a foreign form to the ATO, read the ATO's current guidance, and ask the foreign body whether it will accept a separate ATO certificate if the ATO does not sign its form. Many foreign bodies accept either. If the foreign form also has a part that you must sign in front of a witness, that part may be where a notary helps.

What the foreign body asks for	Who provides it	Notary needed?
"Certificate of residence from your tax authority"	The ATO	No
Its own form, stamped by the tax authority	The ATO, if it agrees, or its own certificate	Usually no
The ATO certificate, apostilled	The ATO, then DFAT	Usually no
A certified copy of the ATO certificate	A notary certifies the copy	Yes, for the copy
A signed declaration on its form, witnessed	You, before the witness the form names	Sometimes
Proof of address or identity	Your documents, certified as asked	Sometimes

Does the ATO certificate need an apostille?

Only if the foreign body asks for one. Many foreign tax authorities and payers accept the ATO certificate as it is, because it is a government document they deal with regularly. Some, however, want it authenticated. DFAT's list of documents it can legalise includes government commercial documents such as those issued by the ATO, so DFAT can generally apostille or authenticate an ATO certificate directly, without a notary.

For countries in the Hague Apostille Convention, that is an apostille; for others, DFAT authentication followed by legalisation at the country's embassy. Check the destination's position on the HCCH status table and DFAT's current requirements on Smartraveller, particularly if the ATO issued the certificate electronically, since DFAT handles only a limited range of electronic documents. Our guide to which documents can be apostilled explains more.

When does a notary help?

A notary is useful at the edges of the process. If the foreign body wants a certified copy of the ATO certificate rather than the original, a notary can certify the copy, and DFAT can then apostille the notary's signature if required. If a foreign form includes a declaration you must sign before a witness, such as a statement about your circumstances or a pension life declaration, a notary can witness it. And if a foreign bank or fund wants certified copies of your passport and proof of address alongside the ATO certificate, a notary can provide those for overseas use.

What a notary cannot do is make a statement about your tax status that the ATO has not made. Our guides to foreign pension documents and overseas bank accounts cover the common forms that do need witnessing.

What if you are not sure you are an Australian tax resident?

Tax residency can be complicated for people who have recently moved to or from Australia, spend time in several countries, or have ties in more than one place. The ATO applies its own tests, and a foreign country may also consider you resident under its rules. Treaties often include tie-breaker rules for people resident in both. This is a question for a registered tax agent or tax adviser, not a notary, and it is worth resolving before you ask the ATO for a certificate or claim treaty benefits abroad.

How long is a certificate of residency good for?

A certificate usually confirms residency for a stated period, such as an income year, and a foreign body may want a certificate covering the exact period in which the income was paid. Some want a new certificate every year, or for each payment period. Check what period the foreign body needs before you apply, so the ATO can issue a certificate that matches it, and plan ahead for recurring income so that each year's certificate is ready in time for the foreign deadline.

If the foreign body refunds tax withheld in earlier years, it may accept certificates covering those past periods, provided you were resident then. Ask both the foreign body and your tax agent how far back a claim can go, because limits apply in many countries, and a missed deadline can mean the extra tax withheld is not recoverable.

How do you prepare?

1. Read the foreign body's request and note whether it wants an ATO certificate, its own form, an apostille or copies.
2. Apply to the ATO, directly or through your tax agent, for a certificate covering the right period.
3. Ask DFAT for an apostille or authentication only if the foreign body asks for one.
4. Use a notary only for certified copies or witnessed declarations the foreign body requests.
5. Keep copies of everything you send, and note the period each certificate covers.

What does this look like in practice?

Here is an illustration, not a real case. Hiro lives in Brisbane and receives dividends from a company in Europe. The paying bank withholds tax at the full non-resident rate and says he can claim the treaty rate with a certificate of residence from his tax authority.

He first asks a notary to notarise a declaration that he lives in Australia, but the notary explains that the bank wants the ATO's certificate. Hiro's tax agent applies to the ATO, which issues a certificate of residency for the relevant year. The bank's instructions also ask for it to be apostilled, so he sends it to DFAT, which adds the apostille without any notary step.

In short

Proof of Australian tax residency for a foreign tax authority, bank or fund usually means an ATO certificate of residency, not a notarised declaration. A notary cannot certify your tax residency. If the foreign body wants the ATO certificate authenticated, DFAT can generally apostille it directly. A notary helps only with certified copies or declarations the foreign body separately asks to be witnessed.
