Tax Methodology
Hook
Every number on this site's tax, wealth, and pension pages comes from a formula you can trace back to a source. Here are the formulas, the sources, and the assumptions.
Key Numbers
- 2025–26 ATO bracket table reproduced verbatim
- Binary-search gross↔net solver, 60 iterations, converges ±$0.01
- Wealth reality ceiling = career_gross − est_tax − $80k/yr living expenses
- PCSS pension approximation = final_salary × min(0.75, 0.5 + 0.025 × (years − 8))
Context
The master methodology document linked from every analytical page. Documents the tax engine, the politician wealth computation, the parliamentary pension projection, every assumption, and what the model deliberately does not capture.
Takeaway
The dashboard's numbers are not predictions. They are transparent calculations against public data — invitations to investigate, not findings.
