A rebate can be claimed through your end of year tax return if you incur medical expenses over $2,000 during the one financial year. Anyone can claim the tax offset: there is no upper limit on the amount you can claim, however it is now income tested. The rebate is currently 20 cents for every dollar over the $2000 threshold.
Because this is a rebate rather than a tax deduction, you can claim this even if you do not pay tax. It is claimed at question T9 on your tax return. As always, be sure to check with your accountant or financial advisor. Further details can be found by click here
