This chapter includes data on the income taxes paid by workers, their social security contributions, the family benefits they receive in the form of cash transfers as well as the social security contributions and payroll taxes paid by their employers. Results reported include the marginal and average tax burden for eight different family types.
Methodological information is available for personal income tax systems, compulsory social security contributions to schemes operated within the government sector, universal cash transfers as well as recent changes in the tax/benefit system. The methodology also includes the parameter values and tax equations underlying the data.
The national currency is the Yen (JPY). In 2019, JPY 109.05 were equal to USD 1. In that year, the average worker is assumed to earn JPY 5 228 474 (Secretariat estimate). In Japan, the central government income tax year is a calendar year and the local government income tax year is from April to March. The calculations in this report are based on the tax rules and rates, which are applicable the April 1st.

If an individual applies for a deduction for both earthquake insurance premiums and long-term casualty premiums, the maximum deductible amount is JPY 50 000 in total.
-
Credit for housing loans: A resident taxpayer who constructs, purchases, enlarges or rebuilds a house and finances the cost by means of a housing loan and uses the property as his or her own dwelling is entitled to an income tax credit up to the amount described below for 10 years after the first use of the house, provided that the floor space is not less than 50m2 and that at least half of the floor space is used as the owner-occupied dwelling. The tax credit is calculated based on the remaining housing loan debt amount and the years which the taxpayer has lived in the house. The loan can consist not only from private financial institutions but also from public institutions. This tax credit cannot be claimed by those whose total income is more than JPY 30 million.
1.1.3. Tax schedule
Tax liability is obtained by multiplying the taxable income by tax rate (A) and deducting the amount (B). For example, income tax due on taxable income of JPY 7 million is:
7 000 000 x 0.23 (A) - 636 000 (B) = JPY 974 000.
In addition, a taxpayer is required to file tax returns and make tax payments for additional 2.1% of the base income taxes from 2013 through 2037 (special income tax for reconstruction) annually together with the regular income tax of respective years.
1.2. Local taxes (personal inhabitant’s taxes)
1.2.1. General description of the system
Local taxes in Japan (personal inhabitant’s taxes) consist of prefectural inhabitant's tax levied by prefectures and municipal inhabitant’s tax levied by cities, towns and villages. The prefectural inhabitant’s tax is collected together with the municipal inhabitant’s tax by cities, towns and villages.
1.2.2. Tax base
Basically, personal inhabitant’s taxes (prefectural and municipal inhabitant’s taxes) consist of two parts; one is income based tax and the other is a fixed per capita amount. The taxable income of personal inhabitant’s taxes is computed on the basis of the previous year's income. The main difference from state tax (income tax) is the amount of income reliefs (tax deductions). For example, the amount of personal deduction and tax deduction for dependants is JPY 330 000, and tax allowance for spouse is up to JPY 330 000, the amount of specified allowance for dependants is JPY 450 000, etc.
1.2.3. Tax rate
-
The standard fixed (annual) per-capita amount of Prefectural inhabitant’s tax is JPY 1 500;
-
The standard fixed (annual) per-capita amount of Municipal inhabitant’s tax is JPY 3 500;
-
The standard rate of the income based tax is 10% (Prefectural inhabitant’s tax: 4%, Municipal inhabitant’s tax: 6%, for ordinance-designated cities, Prefectural inhabitant’s tax: 2%, for Municipal inhabitant’s tax: 8%) (*).
(*) The personal inhabitant’s taxes rate and the income tax rate were changed in the FY 2006 tax reform. Adjusted credit (a form of tax credit) was introduced in order to alleviate the tax burden increase arising from the changes in the tax rates and from the difference between the personal allowances (basic tax allowance, tax allowance for spouse, tax allowance for dependents, special tax allowance for dependents, etc.) for national income tax purposes and for inhabitant tax purposes.
Local authorities do not levy the per-capita rate and the income based tax on a taxpayer whose previous year’s income does not exceed a certain amount. For example, in special wards of Tokyo, this threshold is calculated as follows:
-
per-capita rate: (1 + number of spouse and dependent(s) qualified for the allowance for spouse/dependents) * 350 000 (+ 210 000 in case the taxpayer has a qualified spouse or dependent(s)))
-
income based tax: (1 + number of spouse and dependent(s) qualified for the allowance for spouse/dependents) * 350 000 (+ 320 000 in case the taxpayer has a qualified spouse or dependent(s)))

copy the linklink copied!4. Main changes in the Tax/benefit Systems since 1998
As part of the Fiscal Year 1999 tax reform, the highest marginal rate of the personal income tax imposed by the central government was reduced from 50% to 37%. The top rate of the local inhabitant’s tax was reduced from 15% to 13%. A proportional tax reduction was granted with respect to the national income tax and the local inhabitant’s tax. The amount is equal to the lesser of 20% (local inhabitant’s tax: 15%) of the amount of tax before reduction or JPY 250 000 (local inhabitant’s tax: JPY 40 000).
As part of the FY 2005 tax reform, the rate of proportional tax reduction was reduced from 20% to 10% (local inhabitant’s tax: from 15% to 7.5%) and the ceiling was reduced from JPY 250 000 to JPY 125 000 (local inhabitant’s tax from JPY 40 000 to JPY 20 000) as from 2006 (local inhabitant’s tax: FY 2006). In the FY 2006 tax reform, the proportional tax reduction was abolished as from 2007 (local inhabitant’s tax: FY 2007).
As part of the FY 2006 tax reform, the progressive rate structure of national income tax was reformed into a 6 brackets structure with tax rates ranging from 5% to 40%, and the rate of local inhabitant’s tax became proportional at a single rate of 10%.
As part of the FY 2012 tax reform, the upper limit on employment income deduction (JPY 2 450 000) was set for those who earn employment income of more than JPY 15 000 000 as from 2013 (personal inhabitant’s tax: FY 2014).
As part of the FY 2013 tax reform, the tax rate of 45% was set for the income beyond JPY 40 000 000 from 2015 creating a 7 brackets structure.
As part of the FY 2014 tax reform, the upper limit on employment income deduction was determined to be gradually reduced. In 2016 (as for personal inhabitant’s taxes, in FY2017), the limit became JPY 2 300 000 for salary income more than JPY 12 000 000. Moreover, in 2017 (as for personal inhabitant’s taxes, in FY2018), the limit became JPY 2 200 000 for salary income more than JPY 10 000 000.
As part of the FY 2017 tax reform, as regards allowance for spouse and special allowance for spouse, the maximum spousal income qualifying for the tax allowance (maximum JPY 380 000) were raised from JPY 380 000 to JPY 850 000. At the same time, an upper income limit was introduced as a requirement for taxpayers to qualify for allowance for spouse and special allowance for spouse. The reform goes into effect in 2018. (As for personal inhabitant’s taxes, allowance for spouse and special allowance for spouse will be revised similarly. This reform will go into effect in FY2019.)
As part of the FY 2018 tax reform, following tax systems will be revised. The reform will go into effect in 2020 (as for personal inhabitant’s taxes, in FY2021):
-
The amount of employment income deduction and pension income deduction will be reduced uniformly by 100 000 yen while the amount of personal deduction will be raised uniformly by 100 000 yen.
-
The amount of employment income deduction from income exceeding 8 500 000 yen will be reduced to 1 950 000 yen. However, in consideration of child care and long-term care, measures will be taken to avoid increase in burden on households with a dependent relative(s) under 23 years of age and households with a member(s) dependent on care (*).
* Relatives receiving “special deduction for persons with disabilities”
-
A cap of 1 955 000 yen will be put on pension income deduction for pension income exceeding 10 000 000 yen. The deduction will be reduced for pensioners with income other than pension exceeding 10 000 000 yen after deductions.
-
Personal deduction will be diminished for people with total income exceeding 24 000 000 yen after deductions, and the amount will be further reduced gradually to zero when total income exceeds 25 000 000 yen.
Eligible age for cash benefits for dependent children was raised from three to six as from 1 June 2000, from six to nine as from 1 April 2004 and from nine to twelve as from 1 April 2006. Benefit amount has been doubled to JPY 10 000 for the first and second child under the age of three as from 1 April, 2007.

5.1. Average gross annual wage earnings calculation
The source of calculation is the Basic Survey on Wage Structure, published by the Ministry of Health, Labour and Welfare. This survey covers establishments with ten or more regular employees over the whole country, and contains statistical figures for monthly contractual cash earnings in June and annual special cash earnings (such as bonuses) received by various categories of workers. Male and female workers of the manufacturing, mining and quarrying, construction, wholesale and retail trade, transportation and storage, accommodation and food service activities, information and communication, financial and insurance activities, real estate activities sector, professional, scientific and technical activities are the point of departure. Their gross annual earnings have been calculated by multiplying monthly contractual cash earnings by 12 and adding any annual special cash earnings. In the Basic Survey, sickness and unemployment compensations are excluded from cash earnings, but average overtime and bonuses are included.
As far as the Basic Survey is concerned, it covers the whole country, and no special assumption is made regarding the place of residence of the average worker.
5.2. Employer contributions to private pension and health schemes
DB: JPY 2813 billion (FY 2016)
Employees’ Pension Funds (EPFs): JPY 158 billion (FY 2017)
DC: JPY 924 billion (FY2017)
Data of DB and EPFs are the total amount of employers’ contribution and employees’ one and there is no data of those which indicates only employers’ contribution. Under DC schemes, as from January 2012, matching contribution which enables employee to pay additional contribution to employer's one became available. The amount of DC does not include the amount of matching contribution. It is regulated by law that employers’ contribution must be higher than employees’ one.
2019 Tax equations
The equations for the Japanese system are mostly on an individual basis. But the tax allowances for the spouse and for children are relevant only to the calculation for the principal earner. This is shown by the Range indicator in the table below.
The functions which are used in the equations (Taper, MIN, Tax etc) are described in the technical note about tax equations. Variable names are defined in the table of parameters above, within the equations table, or are the standard variables “married” and “children”. A reference to a variable with the affix “_total” indicates the sum of the relevant variable values for the principal and spouse. And the affixes “_princ” and “_spouse” indicate the value for the principal and spouse, respectively. Equations for a single person are as shown for the principal, with “_spouse” values taken as 0.
