You are able to contribute to super if you are under the age of 75, even if you are not working. Make sure you check the contribution caps and limits that apply to everyone.
If you intend to claim a tax deduction for contributions you make and you are aged 67-74, the Government applies a ‘Work test’ which means you need to be in gainful (paid) work for at least 40 hours in a period of no more than 30 consecutive days in the financial year you make your superannuation contributions.
You generally cannot contribute further money to super once you reach age 75, although the Government’s Downsizer Contribution scheme may be available to you if you sell your house. Information about contributing to super, including eligibility for the Downsizer Contribution scheme, is available at the Australian Taxation Office (ATO) website ato.gov.au
