What the Japan calculator includes
Calculation notes
- National taxable income is estimated from gross salary after the salary income deduction and basic deduction.
- Residence tax is estimated at 10% plus a small per-capita levy; municipality-specific differences are not modeled.
- Social insurance is estimated as a flat percentage because premiums vary by prefecture, age, and insurance program.
