Tax Calculator
Enter your annual taxable income in yen to see a quick estimate based on the current Japanese national income tax brackets. It is straight-faced, fast, and a little too pleased with clean tables.
How To Use It
This calculator uses the NTA quick table for national income tax, then adds the reconstruction surtax. It intentionally stays simple: local inhabitant tax, detailed deductions, and deeply personal receipt stories are outside this card.
Assumption
Refund forecast assumes your employer slightly over-withheld during the year, which is the gentlest possible version of tax season.
Use your rough taxable income after deductions, not gross salary. The official quick table rounds down to the nearest ¥1,000 first.

A deliberately pleasant forecast based on a modest withholding cushion. Real payroll withholding can differ, because reality remains committed to detail.

Calculation
For the current bracket, multiply the rounded taxable income by the marginal rate and subtract the bracket deduction. Then add 2.1% reconstruction surtax on top.
The NTA quick table floors taxable income to the nearest ¥1,000 before applying the rate.
