Wage earners who must file a final tax return

Most wage earners are not required to file a final tax return because the calculation and payment of income taxes are completed through the year-end adjustment by the person paying the salary.
However, in principle, wage earners are required to file a final tax return if any of the provisions applies:

1	Your total employment income exceeds 20 million yen.
2	You receive salaries and wages from one source only, and your total income (excluding employment income and retirement income) exceeds 200,000 yen.
3	You receive salaries and wages from two or more sources and your total earnings (excluding primary salaries) and income (excluding employment income and retirement income) exceed 200,000 yen. (Note) However, you need not file a final tax return if your total employment income after subtracting all the tax allowances (excluding the deductions for casualty losses, medical expenses, donations and basic exemption) does not exceed 1.5 million yen, and your total income (excluding employment income and retirement income) is 200,000 yen or less.
4	You are a director of a family company or a relative of the director thereof, and receive interest on loans or rent for properties from the company concerned.
5	The withholding of income tax, etc., is postponed under the Disaster Exemption Act.
6	You receive salaries and wages from those who are not obliged to withhold tax at source.
7	The amount of tax on your retirement income is calculated by a regular method and exceeds the amount of tax withheld.

(Note)

The total amount of employment income (excluding employment income and retirement income) does not include the following:

1 Dividend income from listed stock, etc., and small dividends, etc., which you have chosen not to report in your final tax return.
2 Capital gains of listed stocks, etc., in an account that is designated as withholding tax account, which you have chosen not to report in your final tax return.
3 Interests on specified government or company bonds, which you have chosen not to report in your final tax return.
4 Interests on deposits and savings or bonds and debentures, which are subject to withholding tax at source.
5 Income from similar financial products such as mortgage securities, which is subject to withholding tax at source.
6 Income derived from profits obtained from single-premium endowment insurance (where the term of insurance is five years or less or where the term of insurance is over five years and cancelled within five years), which is subject to withholding tax at source.
