Agents review & lodge

A registered tax agent checks your application, fixes anything off, and lodges it direct to the ABR.

ABN in your inbox

98% issued within 12 business hours. Email confirmation first, ABR letter follows by post.

Why a tax agent? Applications with errors get stuck in manual review for up to 28 days. Ours get checked by a licensed agent before they're lodged, which is why almost all of them come back the same day.

Your ABN, on the official register

Every application we lodge goes direct to the Australian Business Register, the Commonwealth's official record of Australian businesses. Here's what that means for you.

The official record

Your ABN, business names and GST status all live on the ABR, one government record that banks, platforms and customers rely on.

Publicly verifiable

The moment your ABN issues, anyone can confirm it on ABN Lookup, which is exactly what makes your invoices trusted. Try it below.

Keep it current

ABR details must be updated within 28 days of a change, address, activity, trading name. Not sure yours are right? Call 1800 546 526, advice is free.

Check any ABN: free, live from the register

Entity name, ABN status and GST registration in seconds. Sceptical of us? Fair enough, look up our own ABN.

ABN registration questions

How much does ABN registration cost?

Our agent-lodged application is a flat $99 including GST, tax deductible, with GST and PAYG registration available as add-ons in the same application ($27.50 each). (Applying directly at the Australian Business Register is free; you’re paying for registered-tax-agent review, same-day lodgement and phone support.)

How long does it take to get my ABN?

Usually the same day, often within minutes, because agent review keeps applications out of the ATO’s 28-day manual review queue. The form itself takes about 5 minutes.

Do I need a TFN to register an ABN?

It’s strongly recommended: the TFN is how the ATO matches your identity, and applications without one almost always slow down. Have it handy when you apply.

Is ABN Assist a registered tax agent?

Yes. ABN Assist is operated by Australian Registration Office Pty Ltd, Registered Tax Agent 26076969, verifiable on the Tax Practitioners Board public register.

Do I need an ABN if I earn less than $75,000?

Yes, if you are carrying on a business. The $75,000 figure is the GST registration threshold, not an ABN threshold, and the two are separate. There is no minimum income before you need an ABN. What matters is whether you are running a business rather than pursuing a hobby.

Can I get an ABN for free?

Yes. Applying directly at the Australian Business Register costs nothing, and if you would rather do that, the ABR is the place to go. What our $99 buys is a registered tax agent reviewing the application before it is lodged, same-day lodgement, and someone to call if the ABR comes back with a question.

What do I need to have on hand to apply?

Your tax file number, your date of birth, your address, and a short description of what the business does. If you have traded under another name previously, have that ready too. Nothing needs to be uploaded or posted.

What happens if I invoice without an ABN?

The business paying you is required to withhold 47% of the payment and send it to the ATO. Limited exceptions apply, including where the payment is $75 or less excluding GST. You would claim the withheld amount back through your tax return, but you carry the shortfall until then.
