Question: how to calculate income tax japan?
Answer: Example 1 – Single Taxpayer Your taxable income after the basic deduction is 3,000,000 yen (3,380,000 – 380,000). The next 1,950,000 yen of income will go into the 5% bucket and will cost 97,500 yen in taxes (1,950,000 x 5% = 97,500). This leaves 1,050,000 yen in taxable income (3,000,000 – 1,950,000 = 1,050,000).
