Reward table

We will inform you of the compensation for supporting your subsidy application, depending on the amount of the subsidy, as follows:
Calculation is based on a step-wise formula (excess progressive).

SubsidyRemuneration amount (tax included)
Less than 500 millionSubsidy amount x 14% ~
501 million to less than 1,000 millionSubsidy amount x 8% ~
1,001 million to less than 3,000 millionSubsidy amount x 4% ~
3,001 or moreSubsidy amount x 1%~

【One case】
In the case of a subsidy of 1,000 million yen

  • 500 million yen x 14% = 70 yen
  • 500 million yen x 8% = 40 yen

70 + 40 = 1,100,000 yen (tax included)
