My wife earned 140,000JPY in January 2025, and her total income from January to december 2025 was 1,540,000 JPY. Since her income exceeds the annual dependent threshold (1,300,000 JPY), when would her dependent status be terminated?
• Would the termination date be the first day of the month following the month her income exceeded the threshold?
• How is the termination date determined if her annual income exceeds the limit cumulatively?
• In practice, when do insurers (e.g., Japan Health Insurance Association or company health insurance unions) process the removal of a dependent?
I would greatly appreciate any practical experience or guidance regarding this.
