Calculation basis and official references

Reviewed on:

Formula basis

For each candidate, floor withholding at 10.21% through JPY 1 million and 20.42% above it; bisection plus a whole-yen neighborhood scan finds the minimum candidate meeting the target.

Calculation method

This calculator searches for the smallest whole-yen fee that produces at least the requested net payment after Japan’s standard fee withholding and consumption tax.

Exclusions and checks required

  • The recipient is fixed as an individual under the standard fee method; judicial deductions and corporate recipients cannot be selected.
  • Because withholding is floored to yen, the result can differ by a few yen from a continuous algebraic gross-up.
