Questions Frequentes
How are bonuses taxed in Japan?
Bonuses are subject to income tax withholding (based on a special table using your previous month salary), social insurance premiums (health, pension, employment, long-term care), and the 2.1% reconstruction surtax. The effective tax rate on bonuses is typically 15-30% depending on your salary level.
When are bonuses paid in Japan?
Most companies pay twice: summer bonus (natsu no shoyo) in June or July and winter bonus (fuyu no shoyo) in December. Some companies pay a third smaller bonus in March. Payment dates vary by company.
How much is a typical Japanese bonus?
For large companies, 2-3 months of monthly salary per bonus (4-6 months total annually) is common. Small and medium companies may pay 1-2 months total. Some companies pay a fixed amount rather than a multiplier of monthly salary.
Are social insurance premiums capped on bonuses?
Yes. Health insurance premiums on bonuses are capped at a cumulative JPY 5.73 million per year. Pension premiums are capped at JPY 1.5 million per single bonus payment. Any bonus amount above these caps is not subject to the respective premium.
Is bonus guaranteed in Japan?
Bonuses are not legally guaranteed unless specified in your employment contract. Most companies set bonus amounts based on company performance and individual evaluation. During economic downturns, bonuses may be reduced or eliminated.
Can I reduce tax on my bonus?
The withholding rate on bonuses is determined by a tax table based on your previous month net salary. You cannot directly reduce it. However, if too much was withheld, the overpayment is corrected through year-end adjustment (nenmatsu chosei) or your tax return.
