When taxes or foreign exchange rates change, we sometimes need to update prices on the App Store. Starting October 2019, the Japan Consumption Tax (JCT) will increase from 8% to 10%, resulting in a price increase for apps on the App Store and in-app purchases (excluding auto-renewable subscriptions) in Japan. Once the change goes into effect, the Pricing and Availability section of My Apps will be updated and your proceeds will be increased accordingly. You can change the price of your apps and in-app purchases (including auto-renewable subscriptions) at any time in App Store Connect. For subscriptions, you have the option to preserve prices for existing subscribers.
Note that Apple does not administer the collection and remittance of JCT applicable to sales to customers purchasing content on the App Store in Japan. You will continue to be responsible for the collection and remittance of such taxes to the appropriate tax authorities, as may be required by local law.
