Opposition Leader Angus Taylor has unveiled a proposal to automatically index Australia's income tax thresholds to inflation, arguing the change would prevent workers from paying more tax as wages rise. Coalition modelling suggests the average worker would be about $1,000 a year better off after four years and more than $2,000 a year better off by 2035–36 compared with Labor's current tax settings. The policy is estimated to cost $22.5 billion over the first four years, while critics including Treasurer Jim Chalmers say the plan could increase budget deficits unless matched by substantial spending cuts.
