Kyokai Kenpo fiscal 2026 (Reiwa 8) dependent eligibility re-confirmation: submission deadline is December 11The check of whether family members still qualify as dependents on health insurance begins
To ensure proper insurance benefits, Kyokai Kenpo checks whether dependents still meet the requirements. From late October to mid-November 2026 (Reiwa 8), dependent status lists are mailed in turn to workplaces with applicable persons, and the submission deadline is Friday, December 11, 2026.
- 1. List arrivesMailed in turn from late October to mid-November (only to workplaces with applicable persons)
- 2. Check contentsCheck whether the listed dependents still meet the requirements
- 3. Documents neededIf anyone is being removed, prepare a dependent statement/change notification form
- 4. SubmitSubmit the list by Friday, December 11
Key points
- Targets are people likely to have duplicate health insurance eligibility, people likely living apart despite a relationship that requires living together, and people likely to have taxable income in 2025 (Reiwa 7) at or above the threshold (excluding those under 18 as of April 1, 2026 (Reiwa 8)).
- Kyokai Kenpo sends a dependent status list, a leaflet, a dependent statement/change notification form, a flyer promoting electronic applications, and a return envelope. Workplaces with no applicable persons do not receive the list.
- If anyone is being removed as a dependent, a dependent statement/change notification form is needed. Even if no one is being removed, the dependent status list must still be submitted.
- The page states that if a dependent (change) notification is not submitted, that dependent also becomes subject to the calculation of the contribution for early-stage elderly persons.
What to do in practice
- Check the dependent status list arriving from late October against actual circumstances (income, living together, other insurance) for each person.
- If anyone is to be removed as a dependent, prepare a dependent statement/change notification form and submit it with the list by December 11.
Once a year, Kyokai Kenpo checks whether people covered as dependents on a family member's health insurance still meet the conditions. Papers arrive at companies in autumn, and must be returned by December 11 this year.
- Late October to mid-NovemberPapers for checking arrive at companies in turn
- Friday, December 11Deadline to return the papers
Points
- Papers arrive only at companies that have people who need to be checked.
- People who live apart, who are also in other insurance, or who may earn at or above the limit are the targets.
- If someone no longer meets the conditions, the procedure to remove them as a dependent is done.
