Japan Income Tax Bracket Calculator
Enter taxable income after deductions—not gross salary—to see the ordinary national income-tax bracket and quick-table estimate. The result keeps national tax separate from resident tax.
2026 ordinary national income-tax estimate for general taxable income only. It does not calculate salary income from gross pay, deductions, tax credits, resident tax, separately taxed income, nonresident withholding, or the high-income minimum-tax rule. Final filing calculations and rounding can differ.

How this estimate works
- The entered taxable income is rounded down below 1,000 yen before applying the National Tax Agency quick table.
- The ordinary national rate table uses seven marginal brackets from 5% through 45%, with the official quick-table deduction for each bracket.
- The estimate adds reconstruction special income tax at 2.1% of the simplified base income-tax amount and shows it separately.

Frequently asked questions
Should I enter gross salary?
No. Enter taxable income after applicable deductions. Use the Japan salary or income-tax calculator first if you only know gross pay.
Does the marginal rate apply to all taxable income?
No. Japan's ordinary income tax is progressive; the quick-table deduction reproduces the lower bracket treatment.
