Who this service is for

This service is for clients who need to review whether a prior Australian tax return should be amended because income, deductions, residency, rental property, CGT or foreign income information may have been incomplete or incorrect.

What this page is not intended to cover (1)

When amendments may be required

Amendments may be required where a prior return omitted income, claimed an unsupported deduction, used an incorrect residency treatment or did not correctly report CGT or rental property information.

Supporting evidence

An amendment position should be supported by appropriate records and a clear explanation of the correction.

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.
