Australia: what to claim, what to file, in what order
Income year 1 July 2025 to 30 June 2026 (2025-26). Everything on this page is specific to Australia, so nothing here is a general rule that quietly does not apply to you.

Figures as published by the Australian Taxation Office for 2025-26. Medicare levy surcharge and study loan repayments are not modelled.
Moves that cut this year's bill
These are the Australia moves you can make yourself, with no adviser and no structure to set up. They only count if the money moves before 30 June.
Salary sacrifice into super
Pay goes into super before tax, where it is taxed at 15% instead of your rate.
Saves the gap between your marginal rate and 15%, so up to 32 cents in the dollar.
Cost: Nothing to set up and nothing yearly.
Sione, 45, nurse in Brisbane, Queensland, on $120,000
Sacrifices $15,000 into super. His employer already puts in about $13,800, so he stays under the $30,000 cap.
$5,550 less income tax and Medicare at 37%, while the fund pays $2,250 at 15%. Net saving about $3,300, and $12,750 lands in his super.
Rule behind it: Concessional cap 30,000 for 2025-26, contributions taxed at 15%
Use unused super caps from earlier years
If you did not use your full super cap in the last five years, you can use the leftover in a big income year.
Can take a large one off bite out of a bonus or a capital gain.
Cost: Nothing to set up and nothing yearly.
Nadia, 52, Perth, sells an investment unit for a $180,000 gain
The 50% discount leaves $90,000 taxable on top of her $95,000 salary. She has $62,000 of unused caps from four earlier years and contributes it all.
About $23,000 less tax at her 39% rate for the year, against $9,300 of contributions tax inside the fund. Roughly $13,700 kept, in one move.
Rule behind it: Carry forward concessional contributions, five year window
