How much does an ABN cost? $99, flat and tax deductible.

One flat fee, with nothing added at the end. What the $99 covers, what the optional registrations cost, and which costs are not the ABN at all.

An ABN application lodged by ABN Assist is a flat $99 including GST, tax deductible, with nothing taken until the last step of the form. That covers registered-tax-agent review before lodgement, same-day lodgement and phone support on 1800 546 526. GST and PAYG registration can go in the same application for $27.50 each. An ABN carries no renewal or annual fee, so once it issues there is nothing further to pay.

Costs that are NOT the ABN

  • Business name: registering a trading name with ASIC costs extra (per 1 or 3 year term), only needed if you trade under something other than your own name
  • Company registration: an ACN/company setup is a different beast entirely. See ABN vs ACN
  • “ABN renewal” letters: there is no such fee. Letters demanding renewal payments are a known scam, bin them

Common questions

What does an ABN cost with ABN Assist?

A flat $99 including GST, tax deductible, with nothing taken until the last step of the form. That covers registered tax agent review before lodgement, same-day lodgement and phone support on 1800 546 526. GST and PAYG registration can be added for $27.50 each.

What am I paying for?

For the review and the safety net: a registered tax agent checks your application against the common rejection traps before lodgement, bundles your GST/PAYG registrations, and picks up the phone when the ATO queries something. With us that’s a flat $99 including GST, and it’s tax deductible.

Are there ongoing fees for an ABN?

No. An ABN has no renewal or annual fee. (A registered business name is separate. ASIC charges for those per 1 or 3 year term.) Beware of invoice-style letters demanding “ABN renewal” fees; they’re a well-known scam.

Is the $99 fee tax deductible?

Yes, fees paid to a registered tax agent for managing your tax affairs are generally deductible, so the real after-tax cost is lower.

Does the price include GST registration?

Yes. GST and PAYG registration can be added to our $99 ABN application for $27.50 each ($55 for both), one round of paperwork instead of two, and required registrations for many rideshare and higher-turnover businesses.
