Japan Individual (Personal) Tax System – Brief Summary

Personal Income Tax System in Japan

All individuals living in Japan, irrespective of nationality, are classified as either “Residents” or “Non-residents”. “Individual income tax” comprises of “self-assessed income tax” and “withholding income tax” and will be levied on the individual's income for the “calendar year”.

“Residents” & “Non-residents” tax payers

Residents: Persons having a domicile (principal base and center of one's life) in Japan and persons having a residence in Japan for one year or more are termed residents. The worldwide income of residents, regardless of the location of the source of income, is subject to income tax.

Non-permanent residents: Residents having no Japanese citizenship and having a domicile or residence in Japan for five years or less within the period of ten years are non-permanent residents. The scope of taxation for non-permanent residents corresponds to that for residents, but tax will not be assessed in Japan on income sourced outside Japan as long as that income is not paid within Japan or is not remitted to Japan. However, the salary paid based on the work in Japan is applicable to domestic-sourced income even if it is paid outside Japan, and income tax will be assessed summing the salary paid within and outside Japan.

Non-residents: Persons not qualifying as residents are termed non-residents. Japanese income tax for non-residents will be assessed on income sourced within Japan.

Scope of personal taxable income

Self-assessed income tax

Self-assessed income tax on residents: Income is calculated using methods established for each of a number of income classifications. The tax is calculated by subtracting the various income deductions from the total amount of income and then multiplying the difference, which is the amount of taxable income, by the progressive tax rates below. Any withholding income tax levied on the income beforehand will be deducted from the calculated tax.

Self-assessed income tax on non-residents: Non-residents are classified by their circumstances into (a) non-residents having an office, etc., in Japan, (b) non-residents continuously engaged in construction or assembly in Japan for one year or more, or doing business through a designated agent in Japan, or (c) other non-residents.

Taxable income is calculated within the scope of income established for each classification. The method of taxation for non-residents will also change in terms of income tax pertaining to 2017 or later. The amount of self-assessed income tax levied on non-residents is, as a rule, calculated in the same manner as for residents (subject to certain limits such as non-application of applicable income deductions and foreign tax deductions). Non-residents who earn salary income paid for services provided in Japan and not deemed subject to withholding tax in Japan must file a individual tax return and pay a 20.42% tax on the total amount of that salary.
