Accelerating $10 billion of income tax cuts for up to 12 million Australians is an option being considered by the Morrison government, as it looks to sharpen the Coalition’s pitch to aspirational voters after months of chaos and disunity.

The tax cuts, worth up to $1350 or $25 a week for median to high income earners, would wedge Labor into matching or bettering the government’s proposal earlier than expected in a move that would affect 94 per cent of taxpayers.

Labor has so far opposed stage two of the government’s 10-year plan on the basis that they were planned so far in advance that they were in the "never-never" and mostly benefited median to higher income earners.

The opposition can afford to match the tax cuts, which were not due to begin until 2022, due to its sizeable $200 billion pre-election war chest bolstered by proposed savings on negative gearing and dividend imputation.
