Withholding Tax (Gensen Choshu) when Redeeming Diamonds

For residents of Japan, income tax and special reconstruction tax will be withheld at the time of diamond withdrawal.

Calculating the Withholding tax (Gensen Choshu)

If your withdrawal amount is 1,000,000 yen or less: 10.21% of the withdrawn amount. If the amount of withdrawal exceeds 1,000,000 yen: (Withdrawn amount - 1,000,000 yen) x 20.42% + 102,100 yen

Since the diamond is withdrawn in USD, it will be converted from USD to JPY on the date you applied for the withdrawal.

More details

Please refer to the "Message" of the PayPal transfer page for details of the JPY conversion, withholding tax, and payment amount. Please note that there is no withholding tax when diamonds are converted to coins.
