Worried you’re missing part of your refund? Remember, the low and middle income tax offset isn’t a refund on its own – it’s used to offset (or reduce) the amount of tax you pay. The offset amount you may be entitled to is automatically applied and could range between $255-$1080, depending on things like your taxable income and how much tax you’ve paid.
Salary sacrifice is an arrangement with your employer to forgo part of your salary or wages in return for your employer providing benefits of a similar value. The sacrificed component of your total salary package is not counted as assessable income for tax purposes, however it will be taxed in your super fund at 15% (which can be less depending on your current marginal tax rate).
It's a good idea to talk to your current superannuation fund to see if they offer contribution splitting - they should be able to help you with the process, but both you and your spouse will need to be members of the same superannuation fund.
There are many financial considerations to think about here, and in some circumstances it might be better to claim the spouse contributions tax offset using 'after-tax' money (i.e. what you receive in your pay) or even to claim a personal super contributions deduction (if eligible) and then split these contributions. You may benefit from contacting your fund, registered tax professional or a financial adviser depending on how complex your personal financial affairs are.
