Why Was My ABN Application Refused? The Reasons, and the Fix (2026)

An ABN application is refused for one of two reasons: the Registrar wasn’t satisfied you’re entitled to an ABN, or wasn’t satisfied your identity was established. Every refusal letter comes back to one of those two tests, and which one failed decides the fix.

That matters, because the two fixes are very different. An identity refusal — documents that arrived late, or weren’t certified properly — usually just needs a clean new application. An entitlement refusal needs evidence, and you have 60 days to object if you think the decision is wrong.

A refusal is also more expensive than it looks. It doesn’t pause anything: your sales keep counting towards the A$75,000 GST threshold, and without an ABN you can’t take up standard GST registration — the only way to claim back the 10% import GST on your stock, which is over A$10,000 on every A$100,000 you land.

What the refusal was about	Typical cause	Usual fix
Identity not established	Documents not received and processed in time; certification defects; no reference number on the documents	Reapply with a complete, correctly certified set
Entitlement not established	No enterprise yet, or no evidence of one; activity statement too thin; hobby or employee work	Object within 60 days with evidence — or reapply once the evidence exists
Not eligible as applied	Still registered for simplified GST (a limited registration entity)	Revoke the simplified registration first, then apply

1. Why was my ABN application refused?

Because the Registrar wasn’t satisfied that you’re entitled to an ABN — or likely to be by the start date you gave — or wasn’t satisfied that your identity was established. Those are the tests in section 10 of the ABN Act, and the refusal letter must tell you which reason applied.

Section 10 says the Registrar must register you if you’ve applied, and the Registrar is satisfied that:

• you are entitled to an ABN, or are likely to be entitled by the date specified in your application; and
• your identity has been established (and, where the form asks for them, your associates’ identities too); and
• you aren’t already registered.

If any one of those isn’t met, the application is refused. Section 13 then requires written notice of the refusal and the reasons for it.

In practice, the ABR says you’ll get a refusal number straight away, and a letter within 14 days confirming the refusal, the reasons and your options, including your review rights. Read the reason on that letter before doing anything else — it tells you which test failed.

A reference number is not a refusal. It means the ABR is checking your details or needs more information. It aims to review those applications within 20 business days and will contact you if it needs something.

2. The reasons ABN applications get refused

Most refusals come down to missing evidence rather than a business that doesn’t qualify: no sign the enterprise has started, an activity description too thin to assess, or identity documents that didn’t arrive — or didn’t pass — in time.

Entitlement reasons

• Nothing has started yet. You can apply before trading, but the ABR expects “commencement activities” — a website or social media account for the business, business cards, licences or insurance, premises, equipment or stock, quotes issued, advice from an accountant, a finance application. You don’t need all of them. You’re expected to have done at least some and to be able to prove it.
• It looks like a hobby. The ABR looks for commercial scale, an intention to make a profit, repeat and systematic activity, records, and the way others in the same industry operate.
• It’s employment. You’re not entitled to an ABN for work you do as an employee, even if the employer calls it contracting.
• The start date doesn’t fit the facts. Entitlement is tested at the date you put on the application. A date well ahead of any real activity is hard to support.

Identity reasons — the ones that catch overseas applicants

• The documents didn’t arrive and get processed within 43 days. Without a TFN, a non-resident proves identity with certified documents posted to the ATO in Albury. The ATO’s rule is that if it doesn’t receive and process them within 43 days, the application is refused — not paused.
• The certification was wrong. Only certain people can certify documents for an applicant outside Australia, and they have to record specific details. A defect means the documents don’t count. (We set out exactly what’s required in our guide to certified identity documents for a non-resident ABN.)
• The documents couldn’t be matched. The ABR tells applicants to record the application’s reference number and send it with the cover sheet. Without it, it says, you may need to lodge a new application.

Overseas-seller reasons worth checking

• The statement of business activities was vague — or said the wrong thing. Non-residents without a TFN must describe their business activities in Australia, and the ABR asks you to say if those only involve making purchases in Australia. “I sell online” tells the Registrar nothing. “We sell our own-brand goods to Australian customers through Amazon.com.au, fulfilled from a Sydney warehouse” tells it what the supplies are.
• You’re already on simplified GST. A business registered under simplified GST is a limited registration entity, and section 8(3) says a limited registration entity is not entitled to an ABN. The ABR’s instruction is to revoke the simplified registration before it can process an ABN and full GST registration.

3. Who is not entitled to an ABN?

Anyone who isn’t carrying on an enterprise in Australia and isn’t making supplies connected with Australia in the course of an enterprise — which covers employees, hobbyists and people with no business activity — plus anyone registered as a limited registration entity.

Section 8 gives two separate ways in. You’re entitled if:

1. you’re carrying on an enterprise in Australia; or
2. in the course of carrying on an enterprise — anywhere — you make supplies connected with Australia.

Companies registered under the Corporations Act are entitled automatically.

That second door is the one most overseas sellers walk through. A seller based overseas, with stock in an Australian warehouse or selling goods into Australia, doesn’t need to be running a business in Australia; making sales connected with Australia is enough on its own.

So the people who aren’t entitled are, broadly:

• Employees, for their employment income — an employer shouldn’t ask you to get an ABN as a condition of employment.
• Hobbyists and anyone whose activity isn’t an enterprise.
• People with no business activity yet and nothing to show they’ve started.
• Limited registration entities — businesses on simplified GST registration.

And some people are entitled but may not need one — the ABR notes that renting out a residential property doesn’t generally create GST or PAYG withholding obligations.

Getting an ABN you’re not entitled to isn’t a shortcut. The ABR says you may face prosecution if you apply for an ABN, register for GST and claim GST refunds when you’re not entitled, and it runs entitlement reviews — including when you reapply after a refusal.

4. ABN application rejected — what now?

Object within 60 days if the decision is wrong on the facts you gave; reapply if the cause was something you can now fix. Either way, fix the actual reason on the letter first.

Objecting. A refusal is a reviewable ABN decision under section 21, so you can object under the same process used for ATO decisions. The ABR’s guidance:

• You have 60 days from receiving the decision to lodge the objection.
• Contact the ABR first — some issues are resolved without a formal objection.
• Give a clear statement of the decision you’re objecting to and why.
• Include evidence you’re carrying on, or starting, a business. The ABR’s examples: two recent tax invoices you’ve issued (to different customers where possible), two recent quotes, invoices for materials or equipment you’ve bought, a business contract, a commercial lease, or an application for business finance.
• If you’re unhappy with the objection decision, you can go to the Administrative Review Tribunal or the Federal Court.

Reapplying. If the refusal was about identity — documents late, certification defective, no reference number — a clean new application with a complete set is usually quicker than arguing the old one. Two things to know: reapplying after a refusal is one of the ABR’s own triggers for an entitlement review, so have your evidence ready; and if you’re on simplified GST, revoke that registration first.

If nothing has happened at all. Under section 13, if the Registrar hasn’t decided your application within 28 days, you can give written notice that you want it treated as refused — which lets you object. The 28 days doesn’t count any time the Registrar is waiting on information it asked you for.

Meanwhile, the GST clock keeps running. A refusal doesn’t stop your sales counting towards the A$75,000 threshold, and if you cross it you may need to register within 21 days. Every month without an ABN is also a month of import GST you can’t claim back under standard registration.

What to do next

Start with the letter. Find the reason, and decide which of the two tests failed:

• Identity — rebuild the document set properly, with the reference number and cover sheet, and reapply.
• Entitlement — gather evidence the enterprise exists or has started, rewrite the activity statement so it says what you actually sell and to whom, and either object within 60 days or reapply.
• Simplified GST — revoke it, then apply for the ABN and standard GST registration together.

All of this can be done yourself. Applying and reapplying on abr.gov.au is free, and so is lodging an objection.

Where a registered tax agent earns their fee is making sure the next application is the last one. That means reading the refusal for what actually failed, writing a statement of activities that matches how the Registrar tests entitlement — and, for an overseas seller, puts you through the right door — and assembling an evidence set that survives an entitlement review. Each refused attempt costs another round of certified documents, international post and weeks of waiting, while the GST threshold keeps counting. Getting it right first time is worth more than any objection.

If you’ve had a refusal letter and aren’t sure which test failed, send it to us. The reason line usually tells us within a few minutes whether this is a paperwork fix or an evidence problem.
