Japan Tax Calculator

Welcome on the Japan Tax Calculator. This website is not the reference, it has been made for you to quickly get an idea of the amount of taxes you might have to pay. Refer to your city office to know exactly how taxation works for you. Feel free to participate in the comments at the bottom of this page. As of 2019, the average salary in Japan is ¥ 4,140,000.

How much do you make a year? (after expenses, if any)

Your net income is:
{{income_net | to_yens}}

Insurance + Pension: {{social_amount | to_yens}} ({{social_percent}}%)
Income Tax: {{income_tax_amount | to_yens}} ({{income_tax_percent}}%)
Resident Tax: {{resident_tax_amount | to_yens}} ({{resident_tax_percent}}%)

Calculation details

Salary {{salary | to_yens}}
Insurance / Pension - {{social_amount | to_yens}}
Income Tax - {{income_tax_amount | to_yens}}
Resident Tax - {{resident_tax_amount | to_yens}}
Net Income {{income_net | to_yens}}

First, the Employment Income Deduction should be calculated (check the table). Remove it from your Salary and you get your Taxable Income.

Please note that in 2020, this calculation will change (not to your advantage, I am afraid).

Your Taxable Income is {{taxable_income | to_yens}}.

Annual Salary Calculation
0 - 1,800,000 The greater of (Annual Salary * 40%) or 650,000
1,800,001 - 3,600,000 (Annual Salary * 30%) + 180,000
3,600,001 - 6,600,000 (Annual income * 20%) + 540,000
6,600,001 - 10,000,000 (Annual Salary * 10%) + 1,200,000
10,000,001 - 15,000,000 (Annual Salary * 5%) + 1,700,000
15,000,001+ ¥2,450,000

If you stay for more than one year in Japan, you will need to pick of those two insurance/pension plans. If you work for a company, they will most likely subscribe you to the Social Insurance which covers both insurance and pension. If you don't, your city/ward office will make you take the National Health Insurance. To my experience, the National Pension is not mandatory in this case but you can ask for it as well.

National Health Insurance

This is around 6% to 10% depending on where you live (for example, there is almost a difference of 4% between Setagaya and Shinjuku). If you have dependents (wife and kids), it also increases this amount. If it is your first year in Japan, you will pay an average of 50,000Y.

National Pension

It is simply 16,410Y / month, so 196,920Y / year.

Your Social Insurance

Insurance is 4,95% of your salary and pension is 9,15% of your salary. The real amount of this tax is actually the double of this, but your company is paying for it.

Your Insurance (and Pension) is {{social_amount | to_yens}}.

The Income Tax calculation is based on your Taxable Income minus the Standard Personal Deduction (which is equal to 380,000Y). This amount needs to be calculated per salary segment using that table. For example your salary was 2,090,000, then you’d have to pay 5% on the first 1,950,000 and 10% on the last 140,000.

You need to add the Special Income Tax for Reconstruction (復興特別税) to this amount. It is 2.1% of the income tax which was calculated previously.

Your final Income Tax is {{income_tax_amount | to_yens}}.

Annual Salary Tax Rate
0 - 1,950,000 5%
1,950,001 - 3,300,000 10%
3,300,001-6,950,000 20%
6,950,001-9,000,000 23%
9,000,001-18,000,000 33%
40,000,001 + 40%

You actually only need to pay the resident tax if you were a resident of Japan on the first of January of that year. The basic calculation is based on your Annual Salary, minus the Employment Income Deduction, minus any deductions you can claim (have a look at the official Guide to Metropolitan Taxes for those). Take 10% of this amount.

Your Resident Tax is {{resident_tax_amount | to_yens}}.
