You can object to an ATO decision, and it costs nothing to lodge. For a standard individual income tax assessment the window is generally two years from the date on the notice. For most other decisions it is 60 days.
When is an objection the right tool?
An objection challenges an ATO position you think is wrong on the law or on the facts. It is not the tool for correcting your own mistake, which is an amendment. Confusing the two wastes the deadline on the wrong process.
- An assessment showing tax owed that you believe is incorrect
- A deduction disallowed that you say is legitimate
- A penalty applied where you say it should not have been
- A residency status determined against you
- Income figures in the assessment that do not match your records
- A refund reduced or refused without explanation
The two that come up most often with working holiday makers are residency treatment and refunds assessed before late arriving exemption paperwork, particularly a Medicare Entitlement Statement that turned up after lodgement. Both often succeed when documented.
What deadline actually applies to you?
The deadline depends on the type of decision. For an individual income tax assessment the objection period is generally two years from the date of the notice of assessment.
For most other decisions, including many penalty and private ruling decisions, the period is 60 days. If that window has already closed, a late objection can still be lodged with a written explanation for the delay, at the ATO's discretion.
What makes an objection succeed?
Structure, not eloquence. The reviewer needs to find four things quickly, and an objection that buries them in narrative comes back with a request for clarification and loses months.
- Which decision is being challenged, by notice identifier and date
- Which specific items are disputed, named precisely rather than as a general disagreement
- What the correct treatment is, and the rule that supports it
- The evidence, attached rather than described
Disputing the whole assessment, rather than the residency determination or the deduction at a named item, is the difference between an objection that is decided and one that is bounced.
What does it cost?
Nothing to lodge. There is no ATO filing fee for an objection. Costs arise only if you engage someone to prepare it, or if the matter eventually escalates to the Administrative Appeals Tribunal, which has its own fee.
Where the disputed amount is a few hundred dollars, a free objection is worth lodging and a tribunal application usually is not.
What happens while the dispute runs?
Interest keeps accruing on any disputed amount through the General Interest Charge, and the ATO can continue collection action unless it agrees to pause it. That is the practical reason not to leave an objection sitting on a hostel desk for three months.
If the objection succeeds, interest and penalties on the disputed portion can be remitted. If it fails, the original amount is still owed plus the interest that accumulated while it was argued. A deferral of collection can be requested while the matter is under review, and it is usually granted where the objection is genuine.
What if the objection is disallowed?
The ATO issues one of three outcomes: allowed in full, allowed in part, or disallowed, generally within about 60 business days. If it is disallowed, the next step is independent review by the Administrative Appeals Tribunal, and beyond that the Federal Court.
For working holiday makers the tribunal is the realistic ceiling. Federal Court costs make no sense for an individual refund dispute, and most legitimate backpacker disputes end months earlier at a corrected assessment.
Can you do this after leaving Australia?
Yes. Nothing in the objection process requires you to be in the country. Documents are lodged and correspondence handled remotely, which is how objections proceed for people who went home in November and received the assessment in February.
The complication is not the objection, it is the correspondence reaching you. An ATO letter sent to a hostel address you left eight months ago is how a two year window quietly becomes an argument about why you responded late.
What decides whether you should object at all?
Two things. The first is whether the ATO is actually wrong. Sometimes it is not, and the honest answer is to accept the assessment rather than spend three months confirming it. Read the reasoning in the notice before reacting to the number.
The second is where the error came from. Most disputes we see trace back to how the original tax return was prepared: a residency item answered without thought, a Medicare position taken by default, a deduction claimed without the substantiation behind it. An objection is the expensive way to fix a decision that was made in ten seconds at lodgement.
