Kakutei Shinkoku | Final Income Tax Return in Japan

If you are a resident in Japan, working as a registered* self-employed operator or a freelancer, you are to receive a set of documents sent from Japanese national tax office in late January. The document is for Final Income Tax Return, to report the amount of income tax due on total net income earned between January 1 and December 31 each year, and the filing process is called Kakutei-Shinkoku 確定申告 which is to be done between 16 of February and 15 of March. 

If you are a company employee and your income is only salary paid from the company you are work for, you don’t need to do Kakutei Shinkkoku as income tax is withheld from your monthly salary and your employer is supposed to make year-end adjustments for you. Therefore, the documents for Kakutei-Shinkoku are basically not sent to company employees. 

* Self-employed individuals must file a notification when they start their business in Japan and the notification is called “Kaigyo Todoke 開業届” in Japanese.
