Who this service is for

This service is for clients who need a preliminary review of an ATO decision, assessment or amendment to determine whether an objection may be available and supportable.

What this page is not intended to cover (1)

Objection review

A supportable objection generally requires review of the ATO decision, relevant time limits, evidence and applicable tax law.

Evidence and reasons

The objection position should be clearly reasoned and supported by relevant documents.

Documents we usually need

The exact records required depend on the facts, but commonly include ATO prefill information, prior-year notices, income statements, rental property records, foreign income records, CGT purchase and sale documents, and ATO correspondence where relevant.

How our engagement process works

We begin with an online enquiry and preliminary scoping review. If the matter is within scope, we confirm the proposed work, fixed fee where appropriate, onboarding steps and engagement terms before work commences.

Important limitations

We do not guarantee any particular ATO outcome, refund, amendment result, objection decision, penalty remission or residency conclusion. The final position depends on the facts, evidence and applicable Australian tax law.
