Both Japan and Australia sit in Asia & Pacific, but their tax structures take different paths. On a $90,000 gross, the effective tax burden in Australia is roughly 3.9% higher than in Japan — driven by differences in Shakai vs Medicare, bracket structure, and personal allowance.
Same nominal gross applied to both tax systems. Currencies aren't FX-converted — compare structures, not purchasing power.
Japan combines a seven-band national income tax with a flat 10% local inhabitant tax and roughly 15% social insurance (health, pension, employment). The system is automatically deducted via the year-end adjustment (nenmatsu chōsei), so most employees never file a return.
Australia has a tax-free threshold of A$18,200 and four progressive brackets. The 2% Medicare Levy funds public healthcare; high earners without private cover pay an additional Medicare Levy Surcharge. Superannuation (currently 11.5%) is paid by the employer on top of gross salary, so it doesn't reduce take-home pay.
