Editorial
A neutral overview of the NISA growth investment quota: eligible products, how to use the allowance, what happens after a sale, and how losses are treated.
Contents
The growth investment quota in the new NISA (Japan’s tax-free investment account scheme) is the part of the system that lets investors choose from a wide range of products, including individual stocks, ETFs and investment trusts. Because the choice is so broad, there are several things worth sorting out before using it. This article walks through the basics and the points to check, without recommending any product or financial institution.
The basics of the growth investment quota
The new NISA has two parts, the accumulation investment quota and the growth investment quota, and both can be used in the same year. The established figures are as follows.
| Item | Accumulation quota | Growth quota |
|---|---|---|
| Annual investment limit | 1.2 million yen | 2.4 million yen |
| Annual limit when both are used | 3.6 million yen | |
| Lifetime tax-free holding limit | 18 million yen (of which up to 12 million yen can be in the growth quota) | |
| Holding period | No expiry | |
Gains and dividends earned inside a NISA account are not subject to the tax that normally applies, which is about 20.315%. The rules can be revised from time to time, so please check the latest details on the Financial Services Agency’s NISA website or other official sources before acting on any figure here.
It also helps to remember what the quota is not. It is not a separate pot of money provided by the government, and it does not reduce the risk of the underlying investments. It is simply a limit on how much new money can be placed into the tax-free wrapper each year, and an overall ceiling on the cost basis you can hold inside it.
Eligible products and what a wide choice means
Within the growth quota you can buy listed stocks, ETFs, REITs and investment trusts. Not every product qualifies, however, and those that fail certain conditions are excluded. The simplest habit is to confirm on your broker’s screen or in the product description that an item is eligible for the growth quota before buying.
A wide choice cuts both ways.
- Upside: you can combine stocks, ETFs and funds to suit your own thinking about regions, sectors and styles.
- Downside: you carry more of the work of comparing price movements and costs across products, and concentrating in one stock exposes you heavily to that company’s results and share price.
- Dividend-paying stocks may pay tax-free dividends, but dividends can also be cut or stopped, so the income is not fixed.
Another practical point is cost. Individual stocks and ETFs may carry trading commissions or bid-ask spreads, while investment trusts carry ongoing fees built into the fund. These differ by product and by provider, so they are worth comparing in the product documents rather than assuming they are similar.
Things to consider when using the allowance
The 2.4 million yen annual allowance can be used in one go or spread out. Each approach has trade-offs.
- Using it all at once: the outcome depends heavily on the price at the time of purchase, and later price swings affect the whole amount.
- Spreading it out: purchase timing is diversified, which tends to smooth out the effect of price moves, but it takes more effort and, where trading fees apply, costs can add up.
- Of the 18 million yen lifetime limit, only 12 million yen can go to the growth quota. A large allowance does not mean it should be filled; whether the money is truly spare comes first.
As a hypothetical, investing 200,000 yen a month for 12 months comes to 2.4 million yen (200,000 x 12), which would use up the annual growth allowance exactly. In practice, it is more important to check first whether such a monthly amount fits comfortably within the household budget, including irregular costs such as repairs, travel and taxes. A Japanese-language tool, the recurring investment simulator (Japanese), lets you try different amounts.
After a sale: the allowance and the treatment of gains and losses
When you sell a product held in a NISA account, an amount equal to its original purchase cost (book value) becomes available again from the following year. It is the purchase cost that is restored, not the sale proceeds, and this is easy to overlook.
Suppose, hypothetically, that you bought something for 1 million yen and sold it at 1.5 million yen. The allowance restored is 1 million yen, not 1.5 million yen. The 500,000 yen gain would normally be taxed at about 20.315% in a taxable account, which works out to 101,575 yen (500,000 x 0.20315), but inside NISA it is tax-free.
There are also restrictions to be aware of.
- A loss on a sale cannot be offset against gains in other accounts.
- The loss cannot be carried forward to later years either.
- For foreign stocks and ETFs, tax may be withheld in the source country, and the Japanese NISA exemption may not cover that part.
Because of these rules, the same price movement can lead to different after-tax results depending on the account used. Comparing NISA with an ordinary taxable account side by side makes the differences easier to see. Our editorial policy explains how we approach such comparisons.
Timing of sales also matters for planning. Because the restored allowance only becomes available from the following year, selling in December and wanting to reinvest immediately will not work the way some people expect. Planning around the calendar, rather than reacting to price moves, keeps the decision tied to your own goals.
Points to consider and risks
The tax advantage does not change the fact that the principal is not protected. Writing down the following points can help organize your thinking.
- Price risk: the value of what you buy can fall below the amount you paid.
- Treatment of losses: because losses cannot be offset or carried forward, they are handled differently from a taxable account.
- Concentration risk: holding only a few stocks or one region tends to produce larger swings.
- Spare funds: check that living expenses and money needed within a few years are not being directed into the quota.
- Rule changes: allowances and eligible products can be revised, so the latest information should be confirmed with the Financial Services Agency or similar sources.
