Australian tax numbers, worked out properly
Almost every Australian tax rule changed on 1 July 2026. Stamp duty thresholds moved, the second tax bracket fell to 15%, and the HECS threshold jumped again. These calculators use the new numbers, with the source shown for every one.

Three changes worth knowing about
The ACT abolished stamp duty for first home buyers
From 1 July 2026, eligible first home buyers in the ACT pay nothing, with no price cap and no income test. It is the first place in Australia to go that far. See the ACT rules.
Tasmania's exemption quietly ended
Tasmania's full exemption for homes up to $750,000 finished on 30 June 2026 and was not extended. First home buyers there now pay the same duty as everyone else, and a lot of pages online have not caught up. See the Tasmanian rules.
WA lifted its thresholds by $100,000
The full exemption moved from $500,000 to $600,000, and the concession ceiling from $700,000 to $800,000, across the whole state. See the WA rules.
