- For
- Japanese part-time workers, students, and dependents
- Worth noticing
- It distinguishes annual tax income from the forward-looking income estimate used for health-insurance dependency, and treats commuting allowance differently for those checks.
Field notes
The form asks users to count wages by the date they were paid, not the month they worked, and explains that distinction in its FAQ. It treats tax thresholds as based on January–December wages while health-insurance dependency is assessed using expected future income. The page also notes that commuting allowance can count toward the insurance assessment even when it is excluded from the tax calculation.
