Kakutei Shinkoku (Income Tax Report)
Income tax is automatically deducted from monthly salaries in the case of salary earners, but others must submit kakutei shinkoku (income tax report) to the tax office.
Income tax is paid based on a reporting and payment system by which the taxpayer (who best knows his/her own income circumstances) calculates the tax and pays the tax according to the tax laws.
