Tax file numbers and super contributions

Additional income tax

Members do not have to provide you with their TFN. However, if they don't, you must pay additional income tax on those contributions that form part of the fund's assessable income.

The contributions that are taxed in this way include:

contributions made by an employer on behalf of a member, including salary sacrifice contributions
any part of a transfer from a foreign super fund that is assessable income of the fund.

Applying extra tax

Complying fund

If your member has not quoted their TFN by the end of your income year and their account was opened:

before 1 July 2007 - then the assessable contributions will be taxed an extra 31.5% when those contributions reach or exceed $1,000 in an income year (the extra tax is on all assessable contributions made in that income year, including the first $1,000)
on or after 1 July 2007 - then all the assessable contributions made during the income year will be taxed an extra 31.5%.

The extra tax on these assessable contributions is in addition to the standard 15% rate of tax you pay on your taxable income.

Non-complying fund

Non-complying funds must pay an additional 1.5% tax on assessable contributions if a member has not provided their TFN.
