What this document is
Your answers decide (1) how many tax certificates the supporter needs and for which fiscal years, (2) whether payslips are submitted instead, (3) whether you must prepare a return envelope. A wrong answer means wasted trips or a returned application.
What it must show
- Registered before 1/1/2025 → the full set of three: 課税証明書 Reiwa 8 nendo · 2025 income (latest) ＋ 課税証明書 Reiwa 7 nendo · 2024 income ＋ 納税証明書 Reiwa 7 nendo · 2024 income.
- Registered during 2025 → only fiscal year 8 exists. Submit 課税 ＋ 納税 both for Reiwa 8 nendo · 2025 income; the payment certificate still showing an outstanding balance is NORMAL as long as nothing is overdue. Add three payslips, because the 2025 income may only count from your arrival.
- Registered on or after 1/1/2026 → no tax certificate exists yet; the first one comes around June 2027 (令和9年度). Replace it with a certificate of employment ＋ the last three payslips ＋ a short written reason (理由書).
- Common trap: arriving in November or December still gets you a 住民票 by 1 January, so a certificate DOES exist — but it only shows one or two months of income. Having the paper is not the same as proving your finances; add payslips anyway.
Notes
If you are unsure, leave it blank — the app then shows the FULL set, which is the safe side: extra papers are accepted, missing ones get you sent home.
