  • What you need to understand about income tax

Income tax is not directly calculated based on your total income (something like “XX% of total income”). The calculation will take your personal situation into consideration, such as “Whether you have family members” or “Whether your family members have income”. After a certain amount of deduction is applied upon your total income, a designated amount of percentage is calculated and then your income tax is fixed.  This deduction is called “Koujo”.
