Taxes and insurance for international students in Japan
Even with no income, a student in Japan has payments to make: National Health Insurance and — from age 20 — National Pension. Both can be cut sharply if you file the right papers in time. With a part-time job come taxes — but only above certain limits. What to file in your first year, how to get the pension Special Payment System for Students, how much you can earn tax-free, what tax treaties change for students and what immigration checks from 2027.

In short
What a student pays
Health insurance with no income
The 70% reduction — only after an income declaration
The National Health Insurance premium has two parts: a fixed part per person and a part based on last year’s income (income minus ¥430,000). With no income in Japan there is no second part, and the first is reduced — but only if the city knows your income.
| Premium of a single student, Shinjuku, FY2026 | A year |
|---|---|
| No reduction: medical part ¥47,600 + support for the elderly ¥17,600 + child and childcare support contribution ¥1,873 | ¥67,073 |
| 70% reduction: household income last year up to ¥430,000, income declaration filed | about ¥20,120 (≈ ¥1,677 a month) |

Pension
The Special Payment System for Students (学生納付特例) or an exemption
National Pension is ¥17,920 a month (April 2026 to March 2027) and ¥18,290 from April 2027. A student does not have to pay now: if your school is on the list, apply for the Special Payment System for Students; if not, apply for an exemption.
Is your school on the list? Check the Japan Pension Service list of eligible schools (学生納付特例対象校一覧).

Ask us which of our partner schools are accredited — their students can use the student system.
Part-time work: income limits
How much you can earn without tax
The limits are for a single student whose only income is a salary. Income tax goes by the calendar year; resident tax by last year’s income.
| What | 2025 income | 2026 income |
|---|---|---|
| Income tax (所得税): no tax on a salary up to | ¥1,600,000 | ¥1,780,000 |
| Resident tax, Tokyo: no tax on a salary up to | ¥1,100,000 (2026 tax, from June 2026) | ¥1,190,000 by our calculation (Tokyo confirmed the ¥740,000 minimum deduction; Nagoya announced ¥1,190,000) (2027 tax) |
| Working student deduction (勤労学生控除): income (所得) up to | ¥850,000 (salary up to ¥1,500,000) | ¥890,000 (salary up to ¥1,630,000) — in income tax |
| 70% health insurance reduction: last year’s income (所得) up to | ¥430,000 (Shinjuku, FY2026) | — |
Example
A student works 28 hours a week all through 2026
Simplified: all year at Tokyo’s minimum wage of ¥1,280 an hour (in force from October 1, 2026), health insurance with the reduction, pension under the student system.
| Step | Amount |
|---|---|
| Salary for 2026: 28 hours × 52 weeks × ¥1,280 | ¥1,863,680 |
| − Deduction for employment income (2026) | ¥740,000 |
| = Income (所得) | ¥1,123,680 |
| Income tax for 2026: − basic exemption ¥1,040,000 − premiums ≈ ¥20,000 → taxable ≈ ¥63,000 × 5% × 102.1% | ≈ ¥3,200 for the year |
| Resident tax 2027 (Tokyo): − basic deduction ¥430,000 − premiums ≈ ¥20,000 → ≈ ¥673,000 × 10% − ¥2,500 + ¥5,000 | ≈ ¥69,800 for the year, from June 2027 |
| Health insurance for FY2027 | no 70% reduction any more: income above ¥430,000 |
Income tax is almost nothing, but resident tax arrives in June 2027 — sometimes after you have finished school. Put it in your budget. At 20 hours a week (about ¥1,330,000 a year) there is no income tax, and resident tax comes to about ¥16,600 by calculation (about ¥5,000 if your school qualifies for the working student deduction).

Tax treaties and students
Can a tax treaty exempt your part-time wages?
Japan has tax treaties with many countries, and most of them have an article on students. What it covers depends on the treaty — so check yours before you count on it.
The forms in English: NTA — Application forms for income tax conventions. Money from abroad in general: income from abroad.

Extending your visa
What immigration checks from 2027
Linked to your visa.
- Cities are due to share National Health Insurance payment data with immigration from June 2027 (planned), and immigration will use it when you apply to extend or change your status of residence.
- Once this starts, with unpaid National Health Insurance, an extension or change of status will in principle be refused unless the debt is paid or there is a payment plan. This applies to students too.
- Breaking the part-time rules (more than 28 hours a week, or work without permission) can lead to a refused extension.
