Japan Income Wall Simulator 2026 | Check the ¥1.06M / ¥1.3M / ¥1.78M thresholds

Based on Japan's current 2026 rules, see how far your annual income is from the ¥1.06 million social-insurance threshold, the ¥1.3 million dependent threshold, and the ¥1.78 million income-tax threshold, and what changes if you cross each one. Your numbers are processed entirely in your browser and never sent anywhere.

This tool is designed for people working as a dependent of a spouse (or similar). Students are subject to a different set of rules (such as the working-student deduction), so the dependent-related thresholds shown here (¥1.06M, ¥1.3M, etc.) do not directly apply to students.

How to enter your income
Dependent-status category

The amounts and hours you enter are processed entirely inside your browser and are never sent anywhere.

These are estimates only. Please confirm exact amounts and requirements with your employer, the Japan Pension Service, or the tax office. This is not individualized tax or social insurance advice.

Distance to each threshold

Enter your annual income (or hourly wage x monthly hours) to see the distance to each threshold instantly.

How to use

  1. Enter your annual income, or estimate it from hourly wage x monthly working hours.
  2. Select your dependent-status category (general / age 19–22 / age 60+ or disabled).
  3. See instantly how far you are from each of the three thresholds (¥1.06M social insurance, ¥1.3M+ dependent, ¥1.78M income tax), and what changes if you cross them.

How it works

The three thresholds this tool covers

  • Income tax threshold: ¥1.78 million (FY2026 tax reform — a ¥1.04 million basic deduction plus a ¥740,000 minimum employment income deduction)
  • Social insurance threshold (wage requirement): ¥1.06 million (a monthly wage of about ¥88,000, roughly ¥1.06 million a year; this wage requirement is scheduled to be abolished in October 2026)
  • Spousal dependent threshold: ¥1.3 million (general) / ¥1.5 million (age 19–22) / ¥1.8 million (age 60+, or a person eligible for the disability employees' pension)

How the calculation works

  • You can enter your annual income directly, or have it estimated as hourly wage x monthly hours x 12 months (rounded to the nearest yen).
  • For each threshold, if annual income is greater than or equal to the threshold, it is treated as exceeded; otherwise the remaining amount (threshold minus income) is shown.

About the ¥1.78 million threshold

Under the FY2026 tax reform, the minimum guaranteed employment income deduction was raised from ¥650,000 to ¥740,000. Combined with the basic deduction of ¥1.04 million (for total income of ¥4.89 million or less), employment income up to ¥1.78 million is now free of income tax. This reform is already in force as of August 2026, per the National Tax Agency's official guidance ("About the FY2026 increase in the income tax basic deduction"). This tool assumes total income of ¥4.89 million or less (roughly ¥6.65 million in salary), and does not handle the more detailed deduction schedule for higher earners.

About the ¥1.06 million threshold

One of the requirements for a part-time worker to be enrolled in an employer's social insurance (employees' pension and health insurance) is a scheduled monthly wage of at least ¥88,000 (roughly ¥1.06 million a year). Under the 2025 pension reform law, this wage requirement is scheduled to be abolished in October 2026, per an announced date from the Japan Pension Service. After that, enrollment will be determined by other requirements such as working 20+ hours per week. A separate employer-size requirement also applies (currently companies with more than 51 employees; expanding in stages from October 2027 onward).

About the ¥1.3 million spousal dependent threshold

The basic annual income requirement to be certified as a dependent for social insurance purposes (or as a National Pension Category 3 insured person) is under ¥1.3 million. Exceptions:

  • Age 19–22 (excluding a spouse): under ¥1.5 million (October 2025 revision)
  • Age 60+, or a person eligible for the disability employees' pension: under ¥1.8 million

From April 2026, dependent certification can also be based on projected income under an employment contract, not just actual past income. A separate special measure (employer certification of a temporary income increase) can also allow continued dependent status if the excess is temporary.

What this tool does not calculate

This tool does not calculate the exact amount of tax or insurance premiums you would owe after crossing a threshold — those depend on individual deductions, premium rates, and your employer's size. Please confirm exact figures with your employer's payroll department, the Japan Pension Service, or the tax office. This tool is not designed for students, who are subject to different rules such as the working-student deduction.

FAQ

Is the ¥1.78 million figure confirmed, or still under discussion?

As of August 2026 it is confirmed. In 2025 the threshold was raised from ¥1.03 million to ¥1.6 million, and a further FY2026 tax reform raised it again to ¥1.78 million. The National Tax Agency has officially published this based on law already in force as of May 2026 — it is not a proposal still under discussion.

What is going to happen to the ¥1.06 million threshold?

In October 2026, the wage-based requirement for social insurance enrollment (a monthly wage of about ¥88,000) is scheduled to be abolished, according to the Japan Pension Service. After that, enrollment will instead be determined by other requirements, such as working 20+ hours per week, so the ¥1.06 million yen figure itself loses most of its meaning. A separate employer-size requirement will keep expanding in stages.

Can students use this tool?

This tool is designed for people working as a dependent of a spouse or family member, and is not intended for students. Students are subject to different rules, such as the working-student deduction, so the dependent thresholds shown here (¥1.06M, ¥1.3M, etc.) do not directly apply.

Is the income or wage I enter sent anywhere?

No. All calculations happen entirely in your browser, and nothing is sent to any external server.

How much more tax or insurance premium would I pay after crossing a threshold?

This tool does not calculate the exact amount. It depends on individual deductions, premium rates, and your employer's size. Please confirm exact figures with your employer's payroll department, the Japan Pension Service, or the tax office.
