An objection is a formal challenge—not simply a complaint. It should identify the decision, state the grounds fully, connect them to evidence and specify the outcome sought.
Not every ATO communication uses the same pathway. We start with the notice and its review rights.

Read the guideFrequently asked questions
What is an ATO objection?
It is the formal process for asking the ATO to reconsider certain assessments and reviewable decisions.
How long do I have to object?
The time limit depends on the decision. Check the notice and current ATO guidance for that decision.
Can I lodge a late objection?
A late objection can include a written extension request, but an extension is not automatic.
Does an objection pause payment or interest?
Not automatically. The liability and interest can continue while the objection is considered.
What happens after the decision?
The objection decision generally explains further independent review or appeal rights and deadlines.
