Labor is accusing the Coalition of leaving a $12.5 billion “black hole” in its income tax costings following Tuesday’s federal budget. Multiple outlets report that the dispute centres on the figures used to project tax outcomes, with Labor arguing the Coalition’s calculations fail to account for a shortfall of $12.5 billion. The allegation has become a prominent political focus in the immediate aftermath of the budget, with both sides using the numbers to contest the budget’s overall fiscal impact.

The reports describe the controversy as part of a broader political battleground over costings and budget integrity. While Labor asserts there is a significant gap in the Coalition’s tax projections, the coverage indicates the issue is specifically tied to income tax costings rather than other parts of the budget. The dispute underscores how parties are publicly challenging the assumptions and estimates behind the budget’s forecasted revenues and costs.
