How this task was evaluated
Results are ordered by this task's published score. API runs use one prompt and one completion; agent runs use a coding harness with tools and iteration. Inspect the execution method when comparing results.
Objective scores use the benchmark's execution checks. Judge scores use a vision panel's fixed rubric; the published score leaves out a model's own family. Missing values are labelled rather than treated as zero.
Read the brief
This is a benchmarking hypothetical, not tax advice. The figure is as at FY2025-26. For an Australian resident individual in the 2025-26 financial year, state in dollars the taxable income above which the top marginal income tax rate of 45 per cent begins to apply. Give the dollar threshold at which the top bracket starts (the Medicare levy is separate and is not part of this figure). Name the controlling authority that sets the resident individual income tax rates.
