Japan's Residence Tax: Why the Bill Arrives in Year Two

Almost every newcomer misreads their first residence-tax bill. It appears in year two, after a silent first year, and feels like it must be a mistake: a late charge, a system error, someone else's paperwork landing on you. It is none of those. Residence tax (juminzei 住民税) is designed to arrive exactly this way, a full year behind the income it is charging you for. Once you see why it is delayed, the rest of it makes sense too: the roughly 10% rate, the two ways it gets collected, and what happens if you change jobs or leave Japan before it is settled. What looks at first like a trap turns out to be a schedule you can plan around.

What "residence tax" actually is

"Residence tax" is the common English shorthand for two taxes billed together: a prefectural tax (dōfuken-min-zei 道府県民税, or to-min-zei 都民税 in Tokyo) and a municipal tax (shichōson-min-zei 市町村民税, or ku-min-zei 区民税 in Tokyo's special wards). You never deal with them separately — your city, ward, or town collects both as one combined bill and passes the prefectural share along. Anyone who has a residential address in Japan as of January 1 of a given year, and who had income above a small threshold in the previous year, is generally liable for it, regardless of nationality or visa type.

The tax has two parts. The larger part, the income levy (shotoku-wari 所得割), is calculated as a percentage of your previous year's income. The national standard rate is 10% total, typically split as 4% prefectural and 6% municipal (in Japan's larger "designated cities," the split is instead 2% and 8% — the total is still about 10% either way). On top of that sits a smaller flat levy (kintō-wari 均等割) that everyone pays regardless of income — a fixed annual amount on the order of a few thousand yen, combining the prefectural and municipal flat charges (plus, since fiscal 2024, a separate national forest environment tax collected alongside it). Exact flat-levy amounts and small local surcharges can differ slightly by municipality, so treat "about 10% of last year's income, plus a small flat charge" as the reliable rule of thumb rather than an exact figure for your city.

The mechanic behind the "second-year shock": it taxes last year's income

This is the part that catches almost everyone off guard, and it is the single most important thing to understand about this tax: your residence tax bill in any given year is based on your income during the previous calendar year (January 1 to December 31), not your current income. It is not withheld in real time the way income tax (shotoku-zei 所得税) is.

Work through what that means for someone who has just arrived. Say you moved to Japan partway through your first calendar year here and started your first Japanese job. During that first calendar year, you likely had little or no income that Japan taxed for the year before you arrived — so when the notices go out the following June, there is little or nothing to bill you for, and no residence tax notice shows up. It looks, for a while, like the tax simply does not apply to you.

It does apply to you — it is just measuring a different year. The income you earned during that first calendar year in Japan (even a partial year, from whenever you started working through December 31) becomes the basis for the bill that arrives the following year: as a new payroll deduction if you are on special collection, or as a payment notice by mail if you are on ordinary collection (both explained below). That is the "second-year shock" — not a new tax, not a penalty, just the first time the previous-year math catches up with you. Once you are a couple of years in, the pattern becomes routine: every year's bill reflects the year before it, and (outside of a raise, bonus change, or job change) the swings tend to get smaller and more predictable over time.

YEAR 1 You earn income Jan – Dec (a partial year counts) No residence-tax bill billed the following year YEAR 2 JUNE: first bill arrives ≈ 10% of Year 1 income + small flat levy Then withheld monthly, June → May (or 4 mailed slips)
Residence tax is billed on the previous year's income, so a first-year arrival usually sees no bill until around June of year two — when the tax on that first year's earnings finally catches up.

How it gets collected: payroll withholding vs. paying it yourself

There are two collection methods, and which one applies to you depends mostly on your employment status:

If you change jobs or leave employment partway through the year, your outstanding special-collection balance for the current fiscal year does not disappear — depending on timing, it is either collected as a lump sum from your final paycheck (this is generally required if you leave between January and April, and done with your agreement if you leave between June and December) or switched over to ordinary collection, after which you pay the remainder yourself using mailed payment slips.

Leaving Japan before the tax is settled

Residence tax liability is fixed at the moment January 1 passes for a given year — whether or not a bill has actually been issued yet does not change that. That has one important, easy-to-miss consequence: if you leave Japan partway through a year, you can still owe residence tax for income you earned before you left, and simply boarding a plane does not end the obligation.

In practice, people leaving Japan mid-year generally handle this one of two ways: paying off the remaining balance in a lump sum before departure, or appointing a tax representative (nōzei-kanrinin 納税管理人) — someone who stays in Japan and is formally authorized to receive your tax notices and pay on your behalf. Almost anyone with a Japanese address can serve as your tax representative, including a friend, family member, or (with their agreement) your employer; you appoint one by filing a declaration form with your municipal tax division before you leave. If you leave without paying and without appointing a representative, your municipality has no one in Japan to send notices to, and unpaid tax can move into formal collection procedures — so this is worth settling before departure, not after. If leaving Japan is on your near-term horizon at all, it is worth reading this alongside what happens to a pension lump-sum withdrawal claim and other loose ends when you exit the country, since municipal tax, pension, and other close-out steps tend to land in the same stretch of weeks.

What this means if you've just quit or are between jobs

Residence tax is one of several things that keep running on their own schedule even after your job ends — alongside health insurance coverage, which switches to a different system the moment your employer stops covering you. If you have recently left a job, it is worth reading about how health insurance changes after quitting at the same time you are sorting out your residence tax status, since both tend to surface in the same few weeks after a resignation.

A note on municipal variation

The core structure described above — previous-year income basis, roughly 10% income levy, small flat per-resident charge, special vs. ordinary collection — is set at the national level and is consistent nationwide. What can differ by municipality is the exact flat-levy amount, small local surcharges some municipalities add, and specific due dates for ordinary collection installments. None of that changes the basic shape of the tax; it just means your specific notice may not match a number you saw quoted for a different city.

Where to get an answer about your specific situation

This guide explains how the system works in general; it cannot tell you what you personally owe, whether an exemption applies to you, or how to optimize your specific filing. For questions about your own bill, the right first stop is the tax division (zeimu-ka 税務課) of the city, ward, or town office where you are registered — the notice you received will usually have a direct phone number. For anything more involved, such as disputing an assessment or planning around income from outside Japan, a licensed tax accountant (zeirishi 税理士) is the appropriate professional to consult.

This article explains how Japan's residence tax system generally works. It is not tax advice for your individual situation, and it does not cover every exemption, reduction, or municipal variation. For your own bill, contact your municipal tax division; for professional guidance, consult a licensed tax accountant (zeirishi). See the disclaimer.
