What this estimate assumes

Tax year 2026. The bracket tables below were verified against each country's own tax authority on 25 August 2026. They are still a simplified illustration — read the scope before using any number.

  • China — annual comprehensive-income schedule with the standard 60,000 basic deduction (unchanged since 2019). Social insurance and special deductions are whatever you enter.
  • Japan — national income tax only, plus the 2.1% reconstruction surtax; all seven bands including the 45% top rate. Local inhabitant tax is not included. Basic deduction 580,000 yen; the temporary higher deductions for lower incomes (2025-2026 only) are not applied.
  • United States — federal only, single filer, tax-year-2026 brackets with the 16,100 standard deduction. No state tax, no FICA, no credits.

Verify against the official tax authority: State Taxation Administration (China) National Tax Agency (Japan) Internal Revenue Service (United States)
