ATO Amended Assessment Disputes
Disputing ATO Amended Assessments — Legal Guidance
An ATO amended assessment is a revised tax assessment issued by the Tax Office that changes the amount of tax you are required to pay. Amended assessments may arise from audits, data matching, or ATO reviews — and may include penalties and interest on top of the additional tax imposed.
If you have received an ATO amended assessment that you believe is incorrect or unjustified, legal guidance may help you understand your options, prepare a formal objection, and challenge the assessment through the appropriate dispute resolution process.
