Supply your tax file number
Supply your tax file number
Recording your tax file number (TFN) with your super fund is important.
If your fund does not have your TFN on file, it will need to tax any employer contributions above $1,000 per year at the top marginal rate, plus Medicare levy (currently 46.5%). Accounts that begin after 1 July 2007 will have all contributions taxed at the top marginal rate, plus medicare levy (currently 46.5%). In addition, your fund will not be able to accept personal (after-tax) contributions from you if they do not have your TFN.
