You’ve landed a job in Japan, opened a bank account, and then your first payslip arrives looking like a list of subtractions you can’t read. Welcome to the Japanese tax system — famous for being detailed, paperwork-heavy, and full of rules that hinge on something most people never think about: how long you’ve lived here and what visa you hold.
The good news is that Japan is surprisingly generous to newcomers in some areas (especially your first five years), and once you understand the structure it becomes predictable. This guide explains, in plain English, how Japanese taxes work for foreigners — the resident categories that decide what gets taxed, income and inhabitant tax, consumption tax, the inheritance-tax trap that catches long-term residents off guard, and the concrete, legal ways to pay less.
The single most important concept: your tax resident status
Before any rate matters, Japan sorts you into one of three tax categories. This is the equivalent of the most important fork in the road, because it decides which of your income Japan can tax. Note this is tax residency, which is not the same as your immigration “permanent resident” visa.
1. Non-resident
You have no domicile in Japan and haven’t lived here continuously for a year. You’re taxed only on Japan-source income, and salary for work done in Japan is hit with a flat 20.42% withholding (no deductions).
2. Non-permanent resident (NPR) — the five-year sweet spot 🎁
You’re a foreign national with a home/residence in Japan, but you’ve been a tax resident for 5 years or less out of the past 10. You’re taxed on:
- All Japan-source income (your Japanese salary, etc.), plus
- Foreign-source income only if it’s paid in Japan or remitted (sent) to Japan.
The big benefit: foreign income you keep abroad and don’t send to Japan is generally not taxed here. If you have overseas dividends, rent, or investments sitting in a foreign account, that income stays outside Japan’s reach during this window. This is often called the “remittance basis.”
3. Permanent resident (for tax) — worldwide income
Once you’ve been a tax resident for more than 5 of the last 10 years, you become a permanent resident for tax purposes and Japan taxes your worldwide income — foreign income included, whether you bring it to Japan or not.
⚠️ A common myth: “If I spend under 183 days here, I’m a non-resident.” Not necessarily. Japan’s domestic test is about domicile and the center of your life (where your home, family and job are), not a simple day count. The 183-day rule is a separate tax-treaty concept for short-term visitors. You can be a Japanese tax resident in well under 183 days.
Why this matters so much: the transition from NPR to worldwide taxation around year five is the single biggest planning moment for any foreigner with assets abroad. More on that below.
Income tax: how it’s actually calculated
Japan stacks two income taxes on top of each other, which is why take-home pay can feel light.
National income tax (所得税 / shotokuzei)
Progressive, with seven brackets running from 5% up to 45%. You only pay the higher rate on the slice of income inside that bracket — it’s marginal, not a cliff.
On top of the income tax sits a 2.1% special reconstruction surtax (calculated on the tax amount, not your income). Note: tax policy here is shifting — a new national-defense surtax is being phased in while the reconstruction portion is trimmed, so the exact surtax label may change over time. The combined effect on most payslips stays small.
Local inhabitant tax (住民税 / jūminzei)
A roughly flat 10% tax charged by your prefecture and city, plus a small fixed amount (a few thousand yen, including a national forest levy). Two quirks catch foreigners out:
- It’s based on last year’s income, and it’s billed the following June. So in your first year in Japan you often pay little or no inhabitant tax — then it lands the year after.
- You owe it if you’re a registered resident as of January 1. People who leave Japan sometimes still get a bill for the prior year.
Bottom line: national income tax (5–45%) + inhabitant tax (~10%) means a top earner faces a combined marginal rate around 55%. A middle-income worker typically takes home roughly 70–80% of gross after income tax, inhabitant tax, and social insurance.
The “income tax wall” — recently raised
For decades, Japan had a famous threshold (long known as the “¥1.03 million wall”) — the income level below which no income tax was due, made up of the basic deduction plus the minimum employment-income deduction. Part-time workers, students and second earners deliberately kept their income under it.
After years of debate, this threshold has been raised to reflect inflation, lifting the tax-free starting point and easing the “wall” that discouraged people from working more hours. The exact figure has moved in steps and applies to income tax first, with local inhabitant tax following a year later.
Because the numbers are being adjusted in stages, always confirm the current threshold and basic-deduction amount for the tax year you’re filing rather than relying on an old figure.
The other taxes you’ll meet in Japan
Consumption tax (消費税 / shōhizei) — Japan’s VAT
10% standard rate, with a reduced 8% on most food, non-alcoholic drinks and newspapers. It’s built into or added at checkout, so everyone pays it regardless of residency.
Capital gains tax
- Listed shares and securities: taxed separately at about 20.315% (15% national + 0.315% surtax + 5% local).
- Real estate gains: taxed under a separate schedule depending on how long you held the property.
- Crypto: historically treated as miscellaneous income and taxed at your marginal rate (potentially up to ~55%). Reforms are moving to bring certain registered crypto onto a flat ~20% footing — check the current treatment before you file.
Social insurance (社会保険 / shakai hoken)
Not a “tax,” but it takes a big bite — roughly 15% of salary for employees, covering health insurance (~5%), employee pension / kōsei nenkin (~9%), and employment insurance (a fraction of a percent). Your employer matches most of it, and your share is deductible for income tax.
Inheritance & gift tax — the trap that surprises long-term residents
This is the part many foreigners never see coming, so read carefully.
Japan has one of the highest inheritance/gift tax rates in the world — up to 55% — and crucially, the tax is paid by the recipient, not the estate. Whether your worldwide assets are exposed depends on your visa type and how long you’ve lived here:
- “Table 1” visa holders (most work visas — engineer, specialist, instructor, intra-company transferee, etc.) who have lived in Japan 10 years or less out of the past 15 are treated as temporary residents. They’re generally taxed only on assets located in Japan — overseas inheritances and gifts from a non-resident foreign relative are exempt.
- “Table 2” visa holders (permanent resident, spouse of a Japanese national, long-term resident) — or anyone who has lived here more than 10 of the last 15 years — are taxed on worldwide assets, immediately and regardless of where the assets sit.
Key numbers to know: the inheritance basic exemption is ¥30 million + ¥6 million per statutory heir; a generous spousal credit often wipes out a surviving spouse’s bill; returns are due within 10 months of death. Gift tax has an annual ¥1.1 million per-recipient exemption — which is why that casual wire from your parents toward a house deposit can quietly create a filing obligation.
The practical warning: switching from a work visa to a spouse or permanent-resident visa can instantly expose your family’s overseas assets to Japanese inheritance and gift tax. If you have significant wealth abroad, get advice before you change status.
Exit tax
If you hold financial assets of ¥100 million or more and have lived in Japan on a Table 2 visa for 5+ of the last 10 years, leaving Japan can trigger an exit tax — a deemed sale of your securities taxed at a flat 15.315%. Time spent on a Table 1 work visa doesn’t count toward the five years.
One thing Japan doesn’t have
There is currently no annual net-wealth tax in Japan (unlike Switzerland and some other countries).
Filing your taxes: who actually has to do it
Japan’s tax year is the calendar year (January–December).
Most employees never file a return. Your employer runs a year-end adjustment (年末調整 / nenmatsu chōsei) in December that settles your income tax automatically.
You do need to file a final tax return (確定申告 / kakutei shinkoku) — usually between mid-February and 15 March — if any of these apply:
- Your annual income exceeds ¥20 million.
- You have two or more employers.
- You have side income over ¥200,000.
- You want to claim deductions your employer didn’t handle (medical expenses, furusato nōzei donations to many municipalities, first-year mortgage deduction, etc.).
Filing can be done online through the National Tax Agency’s e-Tax system, and you’ll need your My Number (the national ID number every resident receives).
How to legally pay less tax in Japan
Japan rewards people who plan. Here are the most effective, fully legal levers.
1. Use the NPR remittance window (your first 5 years). This is the biggest one. As a non-permanent resident, foreign income you keep outside Japan generally isn’t taxed here. Keep pre-move savings and foreign investment income in separate overseas accounts, fund your Japanese life from your Japanese salary, and avoid remitting foreign income unnecessarily. Keep a clean ledger of remittances — the tax office asks for it. As you approach year five, plan capital-gains timing before worldwide taxation kicks in.
2. Max out NISA (tax-free investing). Japan’s NISA account lets your investment gains and dividends grow completely tax-free, with a generous annual allowance and (under the current framework) no time limit. For a resident investor, it’s one of the best deals available.
3. Contribute to iDeCo (deductible pension). Contributions to iDeCo, Japan’s private defined-contribution pension, are fully deductible from taxable income, with monthly caps depending on your employment type (commonly around ¥23,000/month for a typical company employee, more for the self-employed). Growth is tax-deferred until withdrawal.
4. Do furusato nōzei (hometown tax). Furusato nōzei lets you donate to regional municipalities and have most of it credited back against your inhabitant tax (beyond a ¥2,000 floor) — while receiving gifts (regional food, sake, household goods) often worth around 30% of the donation. It’s close to a free benefit if you stay within your income-based limit. Use the “one-stop” exception to skip filing if you donate to five municipalities or fewer.
5. Claim the deductions you’re owed. Don’t leave these on the table: medical-expense deduction (costs above ¥100,000 or 5% of income), mortgage deduction (a credit of up to 0.7% of your loan balance for up to 13 years on a qualifying home), life and earthquake insurance deductions, and spouse/dependent deductions.
6. Plan the NPR-to-permanent transition. If you have meaningful foreign assets, the move to worldwide taxation around year five — and any later switch to a Table 2 visa — deserves professional advice. Timing capital gains and understanding your inheritance exposure before the status changes can save very large amounts.
A note for US citizens
If you’re American, remember the US taxes its citizens on worldwide income no matter where they live. You’ll file in both countries, but the US-Japan tax treaty, the Foreign Tax Credit, and the Foreign Earned Income Exclusion generally prevent true double taxation on your salary (Japan’s rates are often higher, so the credit usually covers it). Watch the traps: the inhabitant-tax timing lag misaligns the two countries’ tax years, and FBAR/FATCA reporting kicks in once your Japanese accounts cross the thresholds.
Quick FAQ
Do foreigners pay more tax than Japanese people? No — the rates are identical. The difference is scope: how much of your worldwide income and assets Japan can reach, which depends on your resident status, visa type, and years in Japan.
What’s the “5-year rule”? For your first 5 years (within any 10-year window) as a foreign tax resident, you’re a non-permanent resident and foreign income kept abroad isn’t taxed. After that, Japan taxes your worldwide income.
Will my parents’ gift from overseas be taxed? Possibly. Gift tax falls on you, the recipient, with only a ¥1.1 million annual exemption. Whether overseas gifts are caught depends on your visa (Table 1 vs Table 2) and how long you’ve lived in Japan.
Are my stock profits taxed? Listed shares are taxed at about 20.315% — unless you hold them inside a NISA, where gains are tax-free.
Why is my inhabitant tax suddenly huge in my second year? Because it’s based on the previous year’s income and billed a year in arrears. Budget for it.
This guide is general information, not personal tax advice. Japanese tax rules vary by municipality, change frequently, and turn on fine details of visa status and residency. For anything involving the NPR transition, inheritance or gift exposure, exit tax, or cross-border income, consult a licensed Japanese tax accountant (税理士 / zeirishi) or your local tax office.
