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