How does NISA work in Japan?

NISA, short for Nippon Individual Savings Account, is a government-backed investment account that allows individuals to invest in stocks, mutual funds, and ETFs without paying taxes on capital gains or dividends for a set period.

There are different types of NISA accounts, including:

• Regular NISA: A standard account with an annual investment limit.
• Tsumitate NISA: Focused on smaller, recurring investments to encourage long-term saving.
• Junior NISA: Designed for minors under 20 years old, managed by parents or guardians.

Investors can grow their savings tax-free within these limits, making NISA a popular choice for both Japanese nationals and foreign residents.

What does it mean for a tax to be deductible in Japan?

In Japan, a tax deduction reduces the portion of your income that is subject to taxation.

Essentially, it lowers your taxable income, which in turn reduces the amount of income tax you owe.

Tax deductions are different from tax credits; they do not directly reduce the tax itself but reduce the base on which the tax is calculated.

Japan uses a progressive tax system, meaning that the more you earn, the higher your tax rate.

For example, someone with a higher income could be taxed at a rate of 45%, while a lower-income earner might pay only 5–10%.

Because of this progressive system, deductions are especially valuable: reducing taxable income can move you into a lower tax bracket or reduce the portion of income taxed at higher rates, leading to significant savings.

Is NISA tax deductible?

Despite its tax-free growth benefits, NISA contributions are not tax deductible in Japan.

Unlike some pension contributions or certain insurance premiums, putting money into a NISA account does not reduce your taxable income.

The main advantage of NISA is that capital gains and dividends earned within the account are exempt from income tax, rather than providing upfront deductions.

Does Japan have deductibles?

Yes, Japan offers various deductibles that can lower your taxable income, including social insurance premiums.

• Social insurance premiums (health, pension, unemployment): Payments made toward social insurance are fully deductible, helping reduce taxable income while ensuring coverage for health, retirement, and unemployment benefits.
• Life and medical insurance premiums: Premiums paid for approved life and medical insurance policies can be deducted up to certain limits, providing both financial protection and tax savings.
• Donations to approved charities: Contributions to recognized charitable organizations can be partially deducted, encouraging philanthropy while lowering your tax burden.
• Mortgage loan deductions: Homeowners can deduct a portion of their mortgage interest, reducing the amount of income subject to tax and making homeownership more affordable.

These deductibles help reduce the overall tax burden, but NISA investments do not qualify under these categories.

Is a NISA the same as a pension?

No, NISA accounts are not the same as pensions.

Pensions in Japan, such as the National Pension (Kokumin Nenkin) or Employees’ Pension (Kosei Nenkin), are designed to provide long-term retirement income and often come with tax-deductible contributions.

In contrast, NISA is primarily an investment account for wealth accumulation, offering tax-free growth on capital gains and dividends but without any upfront tax deductions.

While both support financial planning, NISA focuses on flexible investing rather than guaranteed retirement income.

What is the difference between a NISA and an ISA?

The main difference is that NISA is a Japanese investment account, while an ISA is a UK-specific savings and investment account.

Both allow tax-free growth, but they operate under different rules, limits, and eligibility criteria.

• Tax treatment: NISA shelters capital gains and dividends from taxes in Japan, while ISAs follow UK tax rules and can include cash, stocks, and other investments.
• Contribution limits: NISA has annual caps of ¥1.2 million for the Tsumitate quota and ¥2.4 million for the Growth quota (combined up to ¥3.6 million per year), whereas ISAs in the UK currently allow up to £20,000 per year, though from April 2027 the cash ISA allowance for those under 65 will be reduced to £12,000.
• Eligibility: NISA is open to all residents of Japan, including foreigners with valid residency, while ISAs are only available to UK residents.

Knowing this key distinction is crucial for expats familiar with ISAs who are considering investing in Japan through NISA.

Can I transfer my existing investments into a NISA?

Currently, you cannot transfer existing investments into a NISA.

Only new investments purchased through a NISA account can benefit from tax-free status.

However, you can continue to manage your existing investments in regular brokerage accounts outside NISA.

Conclusion

NISA offers a flexible and tax-efficient way to grow your investments in Japan, but it is not a tool for reducing taxable income.

Unlike pensions or certain insurance contributions, NISA focuses solely on tax-free growth of new investments, making it ideal for building wealth over time.

Understanding its rules, contribution limits, and differences from other accounts like ISAs ensures you can plan your investments effectively and take full advantage of Japan’s tax-free opportunities.
