Tax file number and Australian business number information for savings accounts and investments

Introduction

This guide explains when people and organisations with savings accounts and investments need to quote their tax file number (TFN) or Australian business number (ABN). Quoting TFNs or ABNs helps ensure every person and organisation pays the correct amount of tax on interest, dividends and unit trust distributions they receive.

Special exemptions apply for some pensioners, most children under 16 years of age and certain non-profit organisations. If you are in one of these categories, refer to the appropriate section of this guide as well as reading the general sections.

For more information about TFNs, including how to get one, see Tax file number essentials. For more information about ABNs, including who is entitled to one and how to apply, see ABN essentials.
