First Year Resident Tax in Japan (2026 Guide)
Many employees notice that their take-home pay is higher in their first year working in Japan, then decreases in the second year. The reason is usually resident tax (住民税).
This guide explains how resident tax works, when it begins, and why it affects net salary differently in your first and second year.
How Resident Tax Works in Japan
Resident tax is a local municipal tax. It is generally around 10% of your taxable income.
Unlike national income tax, resident tax is based on your previous year's income.
Why First-Year Pay Is Often Higher
If you move to Japan or begin employment for the first time, you may have had little or no taxable income in Japan the previous year.
Because resident tax is calculated on the prior year’s income, your first year may involve reduced or delayed resident tax payments.
In practical terms:
- Year 1: Little or no resident tax
- Year 2: Resident tax begins based on Year 1 earnings
Example Scenario
Suppose you earn ¥4,000,000 in your first year.
During that first year, resident tax may not yet apply. However, in the following year, approximately 10% of your prior taxable income will be assessed and distributed across monthly payments.
This often makes second-year take-home pay feel “lower,” even if your salary has not changed.
How Resident Tax Is Paid
Most employees pay through payroll deduction (特別徴収), where resident tax is automatically withheld from salary each month.
In some cases, individuals may receive payment slips directly from their municipality.
Important Considerations
- Taxable income differs from gross salary
- Deductions reduce the tax base
- Municipal rates may vary slightly
- Changing employers can affect payment timing
Planning for Year Two
If you are newly employed in Japan, it is wise to anticipate reduced take-home pay in your second year.
Understanding this timing helps with budgeting and financial planning.
