How do I object to a tax assessment in Australia?

If you disagree with an ATO or State Revenue Office assessment, you can lodge an objection — but there are strict time limits, so act promptly.

Tax

If you disagree with a tax assessment — from the ATO (income tax, GST) or the State Revenue Office (land tax, duty) — you can usually lodge a formal objection. But strict time limits apply, so don’t delay.

Lodging an objection

An objection sets out why the assessment is wrong and the facts and law you rely on. Getting the grounds right the first time matters.

If the objection is refused

You may be able to seek external review — for example at a tribunal or court — again within strict deadlines.

Pay or defer?

Objecting doesn’t always pause the debt. We can advise on payment arrangements or deferral while your objection is decided.

How we help

We prepare objections, meet the deadlines, and pursue review where needed. Book a consult as soon as you get an assessment you disagree with.

Common questions

Good to know

Is there a deadline to object to an assessment?

Yes — strict time limits apply to lodging an objection with the ATO or State Revenue Office, so act promptly.

Do I still have to pay while I object?

Objecting doesn’t always pause the debt. We can advise on a payment arrangement or deferral while it’s decided.
