What is Shotokuzei?
Shotokuzei is a progressive income tax, which is applied to all individuals and companies that receive an income above a certain annual threshold.
This tax is one of the main sources of revenue for the Japanese government, being used to finance a series of public projects and programs, from infrastructure to social programs.
The word "shotokuzei" (所得税) is composed of two Japanese ideograms: "sho" (所), which means "possession" or "property", and "toku" (得), which means "obtaining" or "acquisition". and "zei" (税), which means "tax". Together, these ideograms form the term that means "income tax".
The origin of the term “shotokuzei” dates back to the beginning of the 20th century, when Japan began the implementation of a modern tax system, following the Western model.
In 1922, the country's first income tax law was enacted, establishing the foundations of the system that still exists today. It is a civic obligation and a means of financing government activities.

What is the rate of Shotokuzei?
The Shotokuzei rate is progressive and varies according to the taxpayer's annual income. The higher the income, the higher the rate applied. The rate table is updated annually by the Japanese government and can be found on its official website.
To illustrate, in 2022, the rates vary from 5% to 45%, depending on the income bracket. See below a table with the percentage of tax according to the income of each Japanese citizen.
annual income range | Rate |
---|---|
Up to ¥1,950,000 | 5% |
From ¥1,950,001 to ¥3,300,000 | 10% |
From ¥3,300,001 to ¥6,950,000 | 20% |
From ¥6,950,001 to ¥9,000,000 | 23% |
From ¥9,000,001 to ¥18,000,000 | 33% |
From ¥18,000,001 to ¥40,000,000 | 40% |
Over ¥40,000,000 | 45% |
The rate is applied on the taxpayer's taxable net income, that is, the difference between taxable income and expenses during the fiscal year.
It is important to that these rates can change annually, we recommend checking the information on the official government website or with a professional.

What happens if you evade income tax in Japan?
Tax evasion is an illegal practice and can have even more serious consequences than simply not paying income tax in Japan. Tax evasion occurs when the taxpayer omits information or forges documents to avoid paying taxes.
If a taxpayer is caught evading taxes, he or she could face the following legal and financial consequences:
- Fines and interest: The taxpayer can be fined up to 50% of the owed tax, in addition to daily interest on the owed amount, until payment is made.
- Criminal process: Tax evasion is considered a criminal offense in Japan and can lead to criminal proceedings. The taxpayer may be summoned to appear in court and may be sentenced to imprisonment, additional fines, and the costs of the process.
- Loss of reputation: Tax evasion can have a negative impact on the taxpayer's reputation. If they are convicted of tax evasion, it can damage their professional and personal image, which is very important in Japan.
- Asset seizure: The tax authority can seize the taxpayer's assets, such as bank s and real estate, to recover the owed amount.
- Prohibition on engaging in commercial activities: In extreme cases, the tax authority may prohibit the taxpayer from engaging in commercial activities until the debt is paid.
- Prohibition of leaving the country: In extreme cases, the tax authority may prohibit the taxpayer from leaving the country until the owed tax is paid.
- Seizure of assets: If the taxpayer does not make the payment even after the court decision, the tax authority may execute a seizure order. This means that the authority can confiscate assets from the taxpayer, such as real estate, vehicles, investments, or other assets, until the owed amount is recovered.
