How it works
How progressive tax brackets work
Most income tax systems use 'progressive' brackets: only income within each bracket is taxed at that bracket's rate. Going into a higher bracket doesn't tax all your income at the higher rate — only the portion above the threshold.
Example: with US 2025 brackets, a single filer earning $80,000 pays 10% on the first $11,600, 12% on the next $35,550, and 22% on the remaining $32,850. Total tax ≈ $12,668 (15.84% effective). The 'marginal rate' (next-dollar rate) is 22%.
Effective vs marginal rate
Effective rate: total tax / total income. Reflects the average tax burden. Useful when comparing total tax burden between income levels or scenarios.
Marginal rate: the rate on the next dollar earned. Decision-relevant for whether to take overtime, accept a raise, or contribute to pre-tax retirement accounts (which save at the marginal rate).
Common confusion: getting a raise into a higher bracket doesn't lower your take-home from the previous level. It just means the new earnings are taxed at the higher marginal rate. There's no 'tax cliff' in standard progressive systems.
What this calculator doesn't include
Deductions: standard deduction (US: $14,600 single, $29,200 married for 2024), 給与所得控除 (Japan, scales with income), 基礎控除 (Japan, ¥480k typical). Subtract these from gross income before using this calculator.
Credits: child tax credit, EITC, etc. (US); 配偶者控除 / 扶養控除 (Japan). These reduce tax owed directly, not income.
State/local taxes: US state income tax (0-13%), city tax (some), Japan resident tax (~10% flat), Japan reconstruction surtax (2.1% of national income tax).
Self-employment tax: US SE tax adds 15.3%; Japan national pension and health insurance separately.
Frequently asked questions
›Where do these brackets come from?
Japan: national income tax brackets per 国税庁 (NTA). US: IRS published brackets for 2025/2026. We do not include state/prefecture/local taxes; consult those separately.
›Should I use gross or taxable income?
Taxable income (after deductions). For Japan: 給与収入 minus 給与所得控除 minus 各種所得控除. For US: AGI minus standard or itemized deduction minus QBI deduction.
›Is the Japan reconstruction surtax included?
No — that's an additional 2.1% of national income tax, on top of the bracket calculation. Apply it manually to the total.
›What about resident tax in Japan?
Resident tax (住民税, ~10% flat) is a separate tax administered by your prefecture and city. Not included in this calculator. For total tax burden, add ~10% of taxable income.
›Why is my effective rate lower than I expected?
Because lower income is taxed at lower bracket rates. Even in the 24% US bracket, only the income above $100,525 is taxed at 24%; the rest is taxed at 10%, 12%, and 22%.
›Does this work for capital gains?
Not directly — capital gains have separate rate schedules. US: 0%, 15%, or 20% depending on income. Japan: typically 20.315% flat for stocks. Use this calculator for ordinary income only.
›What's a 'marginal rate' decision useful for?
Knowing your marginal rate helps with: 401(k)/iDeCo contributions (save at marginal rate), Roth vs traditional decisions, deciding whether overtime is worth it after taxes, charitable deduction value.
›Does the data leave my browser?
No. Calculation runs locally; nothing is sent to a server.
