ABN Application Status: How Long It Takes and How to Check (2026)

When you submit an ABN application, one of three things appears on screen: an 11-digit ABN (you are done), a reference number (the ABR is checking details or wants more information), or a refusal number (a letter with reasons follows within 14 days). If you get a reference number, the ABR aims to review the application within 20 business days and, once it approves it, sends a confirmation letter within 14 days. There is no status-tracker page: you check by searching ABN Lookup, which refreshes from the register every hour, or by phoning the ABR with your reference number. Non-residents without an Australian tax file number should expect the reference number, not the ABN, because the ABR cannot identify them from the form, and their certified identity documents must be received and processed within 43 days of submission.

The number matters more than it looks. Without an ABN you cannot register for GST, so import GST credits on stock already on the water wait; and an Australian business customer that pays you without an ABN on the invoice may have to withhold 47% of the payment. A lost reference number costs a fresh application and a duplicate the ABR has to untangle by hand. Below: what each result means, the real timeline, how to check, and the non-resident path with a worked example.

What appears on screen	What it means	What happens next	How long
11-digit ABN	Application successful; details added to the register	Save the confirmation; register for GST the same day	Immediate
Reference number	The ABR needs to check details or wants more information	Review; the ABR contacts you if it needs more; a letter confirms the ABN	The ABR aims for 20 business days; letter within 14 days after approval
Refusal number	Application unsuccessful	A letter within 14 days with reasons, options and review rights	14 days for the letter; 60 days to object

(General information for FY 2026–27, not tax advice for your circumstances. Read on 12 October 2026 from the Australian Business Register’s “Applying for an ABN” and “ABN for businesses outside Australia” pages, business.gov.au’s “Register for an ABN”, the ABN Lookup FAQs and the ATO’s “Copies of identity documents for applicants outside Australia”. Contact details are from the ABR’s “Contact the ABR” page. The 43-day and 20-business-day settings are the ABR’s; confirm them on the live pages before you rely on them.)

1. What is the status of my ABN application the moment I submit it?

One of three results, shown on screen the moment the online form is submitted. The ABR’s own words: “If your application is successful: you’ll receive your 11-digit ABN immediately.” If instead “you receive a reference number it may mean we need to check some details in your application or more information is needed.” And “if your application is unsuccessful, you’ll receive a refusal number.” business.gov.au puts the same three outcomes in one line: “If you give all the information needed, you’ll find out about your ABN as soon as you’ve completed your online application.”

What decides which of the three you get is mostly identification. The ABR says: “Your application will be processed faster if we can identify you from the information you provide, such as your tax file number.” An applicant the ABR can match against existing records, with a clear enterprise description, tends to see the ABN on screen. An applicant it cannot match, or whose answers raise an entitlement question, gets the reference number and goes to review. You can also start an application without all the information and save it, but then “the issuing of your ABN is likely to be delayed.”

Two things to do in the first minute, whatever the result:

• Save the confirmation. With an ABN: “you should print or save the confirmation of your ABN and ABN details.” You can “immediately apply for other business registrations, such as GST.”
• Record the reference number. The ABR, on its page for businesses outside Australia: “When you submit your application, record the reference number you receive. You’ll need it when sending documents or contacting us. If you lose your reference number, you will need to lodge a new application. This will delay the approval as it creates a duplicate application which requires manual intervention.”

A refusal number is not the end of the road, but it is a different article: the reasons the Registrar refuses, and whether to object or reapply, are in why was my ABN application refused.

2. How long does an ABN take?

Minutes if the ABR can identify you and has nothing to check. Otherwise the ABR says: “We aim to review your application within 20 business days and will contact you if we need further information.” After a successful review, “we will send you a letter within 14 days to confirm your ABN.” business.gov.au: “Reviews can take 20 business days and the ATO may contact you for more information.” The ABN Lookup FAQ describes the same path in calendar terms: if information is omitted or cannot be verified, the application “will be processed manually and can take up to 28 days.”

Twenty business days is four calendar weeks, and the clock is an aim, not a guarantee. Three things stretch it:

1. Time waiting on you. If the ABR asks for information, the review pauses until it arrives. The ABN Act’s own 28-day rule makes the point: the time the Registrar spends waiting for information it has requested is disregarded.
2. Identity documents. For a non-resident without a TFN, the review cannot finish until certified documents have been received and processed. Section 4 covers that path.
3. The letter. Even after approval, the confirmation letter is “within 14 days”, by post, to the postal address on the application. The ABN itself is usually visible on ABN Lookup before the letter lands.

There is also a lever most applicants never use. Under section 13 of the ABN Act, if the Registrar has not decided your application within 28 days of receiving it (not counting time waiting on you), you may give written notice that you want it treated as refused. That sounds like a loss, but it is what unlocks the objection process, and in a long stall it is sometimes the fastest route to a decision. Use it with care: a clean reapplication is often quicker than an objection.

What the wait costs is the reason to manage it. An Australian business paying you for goods or services “may have to withhold tax from their payment to you at the rate of 47%” if no ABN is quoted, in the ATO’s words; the mechanics are in no-ABN withholding. And GST registration, which is what turns the import GST on your first consignment into a credit, cannot start until the ABN exists.

3. How do I check the status of an ABN application?

Three ways, and only one of them is online. Search ABN Lookup for your entity name: the ABR says “you can check ABN Lookup at any time to see if the ABN has been successfully processed.” Phone the ABR with your reference number: 13 92 26 in Australia, +61 2 6216 1111 from outside Australia, 8:00 am to 6:00 pm Monday to Friday, Australian time. Or wait for the letter, which arrives within 14 days of the decision either way. There is no “track my application” page on abr.gov.au; every official page sends you to the same instruction, “to check the progress of your application please contact the ABR.”

Each route has a limit worth knowing:

• ABN Lookup shows issued ABNs only. “ABN Lookup receives updates from the Australian Business Register (ABR) every hour”, but “only when an ABN has been issued by the ABR will the public details about the ABN be available on ABN Lookup.” It never shows “pending” or “under review”. If your name is not there, the application is still open or has been refused; Lookup cannot tell you which, and its FAQ says so: “As ABN Lookup does not have access to registration details please contact the ABR for all enquiries regarding the progress of your application.”
• The phone line needs the reference number and your identity. The ABR warns that “when you phone, you may be asked for some details to prove your identity,” and that “high call volumes may result in long wait times.” From Europe or the Americas, 8:00 am Australian eastern time is the previous evening, so plan the call. The ATO’s non-resident cover sheet also says, for the document path: “You don’t need to contact us, we will send correspondence to you at the postal address provided when we have finalised your application.”
• Online services for business is not a tracker. It is the ATO’s portal for entities that already hold an ABN. A first-time applicant has nothing to log in with, so it does not show an ABN application’s progress.

A practical rhythm: search ABN Lookup once a week; if 20 business days pass from the date your documents would have been processed and nothing has appeared, phone with the reference number.

4. How long does an ABN take for a non-resident?

Longer, and mostly for reasons inside your control. Without an Australian TFN the ABR cannot identify you from the form, so a non-resident should expect a reference number rather than an ABN on screen; the application then waits for certified identity documents, and the ABR’s rule is that “you must complete the checklist within 43 days of your online application being submitted.” The ATO’s version of the same clock: “If we don’t receive and process your supporting documents within 43 days, your application will be refused.” The 20-business-day review runs after the documents are in. The ABR publishes no separate service standard for non-residents; in our experience the end-to-end time is set by how fast the documents move, not by the ABR.

The checklist on the ABR’s “ABN for businesses outside Australia” page has four steps: a brief statement of your business activities in Australia; proof-of-identity documents (two certified documents for an individual, one of them primary; the certificate of incorporation and director identity for a company); the non-resident cover sheet carrying your reference number; and mailing all of it to the Non-resident Registrations Team. The mailing address on that page changed in 2026, with a separate courier address in Melbourne; copy it from the live page the day you send, not from an older guide. What the documents must look like, who may certify them, and the apostille route are in the certified identity documents, exactly, and the full application is in how to get an ABN as a non-resident.

Where the days go, in the ABR’s and ATO’s own words:

Delay	Source wording
No TFN on the application	“Providing a TFN isn’t required by law but not providing it may result in delays”
Certification that doesn’t meet the rules	“Delays in processing occur where documents you provide to us don’t meet our certification requirements”
Details that don’t match the application	“The application will be delayed, or in some instances, refused”
No cover sheet	“It can cause delays in processing your application, including cancellation of the application”
Lost reference number	A new application, “a duplicate application which requires manual intervention”
International post	The clock is received and processed, not postmarked; the ATO says to send documents “as soon as possible after you submit”
A prior simplified GST registration	It “will need to be revoked before we can process an ABN and full GST registration”

Elena runs a Spanish company and is shipping its first pallet to a Melbourne 3PL. She qualifies for an ABN because she will make supplies connected with Australia; the entitlement is not the hard part. The timeline is illustrative, because neither the ABR nor the ATO publishes per-step times.

Day	Elena prepares first, then lodges	Elena lodges first, then prepares
Before day 0	Certificate of incorporation and passport certified by a notary; sworn English translation; cover sheet half-filled	Nothing
Day 0	Submits online; reference number on screen; writes it on the cover sheet	Submits online; reference number on screen
Days 1–5	Couriers the set to the courier address; delivered day 5	Books the notary; appointment day 9
Days 6–20	Documents received and processed (say, day 12); review window opens	Translation back day 16; posted by standard international mail day 17
Days 21–40	ABN issued inside the 20-business-day aim; appears on ABN Lookup; letter follows within 14 days	Envelope arrives day 31; processed day 38, five days inside the 43
Day 43	Already registered for GST	Any slip past here: refused; new application; the whole clock again
Outcome	About six weeks, outer	About ten weeks if nothing slips; sixteen or more after one refusal

Same company, same documents, same entitlement. The difference is sequence. Elena’s import GST on that first pallet becomes a credit only once she is GST-registered, which needs the ABN, so the four extra weeks on the right-hand path are four weeks of cash she has paid at the border and cannot yet claim back.

Where it’s worth getting help

The free path works: apply at abr.gov.au, write down the reference number before you close the browser, send the documents the same week by courier, search ABN Lookup weekly, and phone 13 92 26 with the reference number once 20 business days have passed. Most sole-trader applicants with a TFN never need any of this because the ABN appears on screen.

The judgment calls are these:

• Sequence. Whether to lodge now or to assemble and quality-check the certified set first. The 43 days start at submission, and the notary, the translator and the post all sit inside them.
• Certification wording. A notarial certificate that doesn’t state the certifier’s details the ATO lists, or a translation without the service’s accreditation, restarts the clock in the worst way: at day 43.
• The stall. At day 30 with nothing on ABN Lookup, whether to phone, wait, or give section 13 notice, depends on what the ABR has actually asked for.
• Refusal versus reapply. A refusal number for identity is usually a reapplication; one for entitlement is usually an objection with evidence, and the 60 days run from the letter.

That’s the difference between doing it and doing it right the first time: the seller who had the ABN, the GST registration and the import credit lined up before the pallet cleared, versus the one who found out on day 44 that the documents had been received but not processed.

If you’d like that looked at properly, our initial assessment form scopes it in about twelve questions, without needing a meeting, and our ABN application service handles the document set, the cover sheet and the follow-up with the ABR for you.
