Income tax you feel every payday. Resident tax is the sneaky one — it runs a year behind, so it can land exactly when you least expect it. Mio doesn't panic; Mio reads the timing and plans for it. Here's how it actually works.
Resident tax is a local tax (prefectural + municipal) charged by the city where you were a registered resident on January 1. It's assessed on your previous calendar year's income (Jan 1–Dec 31). Two parts make it up:
• Income levy — about 10% of your taxable income (illustrative; the standard split is roughly 4% prefectural + 6% municipal, and it varies by municipality).
• Per-capita levy — a small flat amount, often around ¥5,000 total (exact figure varies by municipality and year; some areas add a small forest/reconstruction surcharge).
Special collection (tokubetsu chōshū) — most employees. Your employer deducts it from your monthly salary in 12 installments from June through May of the next year. You don't get a bill; it just quietly comes out of your pay.
Ordinary collection (futsū chōshū) — freelancers, the self-employed, and people whose employer doesn't handle it. Your city mails you payment slips (usually four instalments a year, e.g. June / August / October / January) to pay at a convenience store, bank, or by direct debit.
This is the one that catches almost everyone. In your first year in Japan you were not a registered resident on the previous January 1, so there's usually no resident-tax bill — pay looks great. Then in year 2, the tax on your year-1 income arrives, often from June. Suddenly your take-home drops even though nothing changed at work.
Because it always looks back one year, a raise, a bonus, or freelance income shows up on next year's bill — and if you switch to a lower-paying job, you can be paying tax on a higher income you no longer earn.
Here's the part that's easy to miss: since the bill is for last year's income, quitting your job or leaving Japan does not erase it. If you leave part-way through the year, any resident tax still owed doesn't just vanish.
If tax will remain unpaid after you go, your municipality generally requires you to appoint a tax representative (nōzei kanrinin) — a person or company resident in Japan (a friend, employer, or tax accountant) who receives your remaining payment slips and pays on your behalf. You file this at the city office before departure. Alternatively, employees sometimes have the whole remaining balance lump-sum deducted from a final salary or severance (a form of special collection). Confirm which applies with your employer and city office before you leave — chasing it from abroad is painful.
Budget ahead: once you've been here past a January 1, set aside roughly ~10% of your taxable income for the resident tax that will follow the next year. Before quitting or leaving: ask your employer whether they'll lump-sum deduct, and ask your city office whether you need a nōzei kanrinin. Keep your payment slips and address updated so bills reach you.
| Income earned in | Billed / collected in | How you pay |
|---|---|---|
| Year 1 (you arrive mid-year) | Usually no bill — not a Jan-1 resident yet | Nothing that year |
| Year 1's income | From June of Year 2 | Salary deduction (employees) or payment slips |
| Year 2's income | From June of Year 3 | Same — always one year behind |
| Year you leave | Prior-year tax still due | Lump-sum from final pay or tax representative |
Illustrative only. Months, instalment counts, rates, and per-capita amounts differ by municipality and year — your city office is the authority for your exact figures.
