Source notes and FAQ
Which official data does the draft use?
The formulas follow National Tax Agency references for 2026 salary income, basic deduction, income-tax rate brackets, and the reconstruction surtax. Resident tax uses the common 10% standard-rate assumption, with editable local settings.
Why is social insurance a percentage input?
Health insurance varies by prefecture, insurer, age, and standard remuneration grade. A user-editable percentage keeps the calculator useful without pretending every employee has the same payroll deduction.
Will this match my monthly payslip exactly?
No. Monthly withholding, bonuses, year-end adjustment, dependents, commute reimbursements, and municipality rules can all change the result.
