How Much Does an ABN Cost? Nothing — Here's What Does (2026)

An ABN costs nothing. The Australian Business Register charges no fee to apply, no fee to review your application, no fee to reapply if it is refused, and there is no renewal — an ABN never expires on a fee cycle. That is true for residents and non-residents alike. GST registration and a tax file number are free as well. Everything people actually pay for sits next to the ABN, not inside it.

That matters because “how much does an ABN cost” is usually the wrong question, asked at the right moment. The seller asking it is about to spend money — on a website that charges for a free form, on a company a forum told them they needed, or on a second application after a first one was refused. This article lists what is free, what is genuinely chargeable from 1 July 2026, and what a non-resident’s application really costs, which is measured in paperwork and weeks rather than dollars.

	The cost of an ABN in one line
The ABN	A$0 to apply, review, reapply, update, cancel. No renewal fee, ever — ABR
GST registration	No government fee — ATO
A TFN	“It is free to apply” — ATO
A business name (ASIC)	A$47 for one year, A$108 for three, from 1 July 2026 — only if you trade under a name that isn’t your own
An Australian company (ASIC)	A$636 to register, A$342 annual review, plus a resident director — only if you choose that structure
A registered foreign company (ASIC)	Published at the same A$636 — only where the Corporations Act requires it, which an ABN does not
The non-resident “fee”	None. The outlay is certified, translated identity documents, a courier, and a 43-day clock
What a refusal costs	Weeks, not dollars — reapplying is still free

The ABR, ATO and business.gov.au pages quoted were read on 12 October 2026; ASIC fees are the 1 July 2026 figures published by business.gov.au and are indexed to CPI each July. Whether you need an ABN at all depends on your facts.)

1. How much does an ABN cost in Australia?

Nothing. The Australian Business Register’s own line is that “it’s free to register for an ABN through the Australian Government’s Australian Business Register”, and the free part does not stop at the application. There is no charge to update your details, no charge to cancel, no charge to reapply after a refusal, and — the one that surprises people who are used to annual company filings — no renewal fee. An ABN is a registration, not a licence. It does not lapse because a payment was missed, and nobody will ever send you an invoice to keep it.

The two registrations that usually travel with an ABN are free too. Registering for GST carries no government fee; the only cost GST brings is the obligation to lodge activity statements once you are in. A tax file number, if your structure needs one, is free: the ATO’s application page says so in four words. So the full set an overseas seller typically needs — ABN, GST, sometimes a TFN — carries a government price of zero.

What you do pay with is time. If the ABR can identify you and your answers raise no questions, the number is issued immediately. If the application goes to review, the ABR aims to complete it within 20 business days and may contact you for more information; either way a letter follows within 14 days with the ABN or the reason for a refusal. For a non-resident, that review is the norm rather than the exception, and section 3 explains why.

2. Is registering for an ABN free — then why do some websites charge?

Yes, it is free — and people pay anyway, for two very different reasons. One is a look-alike website that charges for the government’s free form. The other is a registered tax agent who charges for advice and for getting the application right the first time. They are not the same purchase.

The look-alikes are easy to describe. Search for “register ABN” and the results include sites with official-sounding names, a form that mirrors the ABR’s, and a fee — typically tens of dollars, sometimes considerably more — for submitting what you could submit yourself for nothing. Some are simply resellers of a free service; the ATO has also warned about scam sites that take the fee and deliver nothing. The test is the address bar: every Australian Government site ends in .gov.au. The ABR is abr.gov.au, and the Business Registration Service that bundles ABN, GST and business-name registration is on business.gov.au. If the site you are on does not end that way, you are paying somebody to type.

A registered tax agent is a different proposition, and it is worth being precise about what the fee buys, because “free at the ABR” and “worth paying for” are both true. The ABR issues an ABN to an entity that is entitled to one. For a seller outside Australia, entitlement is not obvious: the ABR tests whether you are carrying on an enterprise, and — for most overseas sellers — whether your supplies are connected with Australia, which is the limb that stock in an Australian warehouse or sales to Australian customers normally satisfies. Get the answers wrong, or describe your business in a way that trips a review question, and the application is refused — free to resubmit, but every resubmission restarts the clock on your identity documents and delays the GST registration that usually needs to follow. Our article on why ABN applications are refused walks through the reasons; an agent’s fee is the price of not needing to read it.

3. Is there an ABN fee for non-residents?

No. The ABR charges non-residents exactly what it charges everyone: nothing. There is no non-resident surcharge, no paper-application fee, and no fee for the manual review your application will almost certainly go through. What a non-resident application costs is paperwork, and the paperwork has prices attached that the ABR does not set.

Because the ABR cannot verify an overseas applicant against Australian records, you prove who you are with documents. For an individual that means two forms of identity; for a company, documents for the company and for the people behind it. Each copy must be certified — outside Australia, by a notary public, by Australian consular staff, or by way of an apostille — and anything not in English needs a translation from an approved service, itself certified. The notary sets the notary’s fee; the translator sets the translator’s. Then the originals of those certified copies have to reach the ATO physically, so budget for a courier. The exact document set is in our guide to the certified identity documents, exactly, and the timeline — including the rule that the evidence must be received and processed within 43 days of the application — is in how a non-resident gets an ABN.

That 43-day clock is where the real cost of a non-resident application lives. Miss it, or send a certification the ATO won’t accept, and the application is refused. Reapplying is free. But the notary, the translator and the courier are paid again, your Australian stock sits uncleared or your marketplace account sits unverified while you do it, and the GST registration you need behind the ABN waits too. A refusal costs weeks; the “fee” for a non-resident ABN is still A$0.

4. What does cost money around an ABN — and when do you actually need to pay it?

Only ASIC charges, and only for things that are optional for most overseas sellers: a business name, an Australian company, or registration as a foreign company. From 1 July 2026 the figures are A$47 or A$108 for a business name, A$636 to register a company plus A$342 a year, and — published at the same A$636 — registration of a foreign company. Each has a trigger. If the trigger isn’t there, neither is the fee.

ASIC fee (from 1 July 2026)	Amount	When it actually applies
Business name — one year	A$47 (was A$45)	You trade in Australia under a name other than your own, or your company’s own, name
Business name — three years	A$108 (was A$104)	Same trigger; per name, not per business
Register an Australian company	A$636 (was A$611)	You choose to incorporate here — the ABN never requires it
Proprietary company annual review	A$342 (was A$329)	Every year that company exists, plus an Australian resident director
Register a foreign company (ARBN)	A$636 per published fee tables — confirm on asic.gov.au	Only where your company carries on business in Australia in the Corporations Act sense; not a condition of an ABN

Three set-ups, counting government fees only:

• A UK Ltd selling its own brand through a marketplace, under the company’s own name. ABN A$0, GST registration A$0, no business name needed because the company trades as itself. Government fees: A$0. The outlay is the notary’s fee for the director’s passport, a courier, and the time to do it once.
• A sole trader in Guangzhou selling under a brand name through her own Australian-facing store. ABN A$0, GST A$0. If she uses the brand as her trading name in Australia and chooses to register it, a business name at A$47 for a year or A$108 for three. Plus notarised and translated identity documents.
• The forum answer: “you need an Australian company”. A$636 to register, A$342 every year, an Australian resident director to find and pay, a separate company tax return — and no improvement whatsoever to the ABN or GST position, which a foreign company holds in its own name. Our article on ABN registration for foreign companies sets out the three routes; the subsidiary is the expensive one, and it is rarely the right one.

The pattern is the same each time. The ABN is free, the registrations that matter for selling here are free, and the fees that exist attach to structures you may not need. If you are unsure which of the four Australian numbers your business actually requires, ABN, ACN, ARBN, TFN answers it in a page — usually, it’s just one.

Where it’s worth getting help

If you are an individual or a company applying in your own name, with documents in English or a notary who routinely does apostilles, the whole thing is free and you can do it yourself at abr.gov.au. Many sellers do.

The judgment calls — and the places a free process turns into a slow one — are these:

• Do you qualify at all? The ABR tests enterprise and the connection with Australia; the wrong description of a marketplace or 3PL arrangement is the most common reason an overseas application is refused.
• Is the certification one the ATO accepts? Notary, consular, or apostille — and the translation from an approved service. A certified screenshot, or a translation by the wrong person, restarts everything.
• Will the evidence land inside 43 days? International post, a notary’s turnaround and the ATO’s own processing all count against the same clock.
• Do you need a business name or a company — or has someone sold you one? The fee is small; the annual obligations behind a company are not.
• What follows the ABN? GST registration may be required once your connected sales reach A$75,000, and for most overseas sellers it is the registration that was the point.

That’s the difference between doing it and doing it right the first time: the seller who paid nothing to the ABR and spent nine weeks on two attempts, against the one who paid nothing to the ABR and was registered on the first.

If you’d like that looked at properly, our initial assessment form scopes it in about twelve questions — how you sell, where your stock sits, what documents you can get certified — without needing a meeting. When you’re ready, you can start your ABN & GST application online in about ten minutes: scoping questions only, no documents and no payment at the application stage.

FY 2026–27. General information, not tax advice for your circumstances. The ABR, ATO and business.gov.au statements quoted were read on 12 October 2026. ASIC fees are the published 1 July 2026 figures and are indexed each July; the registered-foreign-company fee is taken from published fee tables and should be confirmed on asic.gov.au. Whether you are entitled to an ABN, and whether the A$75,000 GST registration threshold applies to you, depends on your facts.
