If you are a self employ person you are able to contribute to your superfund as a concessional contribution to claim a tax deduction from your individual tax return. if you are an employee whose employer is required to contribute to superannuation are not eligible to claim a tax deduction. Instead the government may make a co-contribution to their fund. To be eligible for the co-contribution your assessable income (including reportable fringe benefits) should be no more than $61,920 for the 2010 income year. You must also be less than 71 years of age at the end of the income year. For the 2010 income year the government will contribute a maximum of $1 for each $1 that you contribute to superannuation with a cap of $1000 per year.
Your employer contributions (including contributions made under salary sacrifice arrangement) are called concessional contributions. The cap limit is for concessional contributions is $50,000. This cap applies until 30 June 2012 for people 50 years old or over. If you were 50 years old or over, the annual cap for the 2007-08 and 2008-09 financial years was $100,000. If you are 50 years old or over, the annual cap for the 2009-10, 2010-11 and 2011-12 financial years is $50,000. If you have more than one fund, all concessional contributions made to all your funds are added together and count towards the cap. This cap is not indexed. If annual contributions exceed the applicable cap amount, the excess will be taxed at the highest marginal rate, plus medicare levy.
Please note; The government has announced changes that, will permanently increase the concessional contributions cap to $50,000 for individuals who have total super balances below $500,000 and are 50 years old or over. These changes have not been passed by the parliment
