❓ What's changing?
From April 2026, social insurance dependent status determination changes from "past actual income" to "projected future income." This means temporary income spikes won't automatically disqualify you from dependent status if projected annual income stays below the threshold.
🔄 How the judgment changes
[Old] Based on past 12 months' actual income
[New] Based on projected next 12 months' income
[Old] Temporary income spike = lose dependent status
[New] Employment contract & conditions used to project income
[Old] Exceeding ¥108,333/month continuously = immediate removal
[New] Temporary exceedances handled flexibly
🧱 Impact on the ¥1.3M wall
The ¥1.3M annual income wall (¥108,333/month) remains, but with "projected income" basis, working extra during busy periods won't disqualify you if annual projection stays under ¥1.3M.
👥 Who's most affected
- ●Part-time working spouses
- ●Those who increase shifts during busy seasons
- ●People with multiple jobs
- ●Part-timers returning from parental leave
⏱️ Earlier determination timing
Dependent status will be determined promptly when employment contracts or work conditions change. Shifting from "post-verification" to "pre-emptive/ongoing assessment."
