Using the New NISA Growth Investment Slot - Maximizing Tax-Free Benefits with Individual Stocks
Reading time: about 4 min
The Growth Investment Slot of the new NISA launched in 2024 (annual limit of 2.4 million yen) allows dividends and capital gains on individual stocks to be received tax-free. This article covers the structure, eligible products, strategies for individual stock investing, and constraints to be aware of.
Overview of the New NISA
The new NISA (Nippon Individual Savings Account) launched in January 2024 consists of two slots: the Tsumitate (accumulation) Slot (annual limit of 1.2 million yen) and the Growth Investment Slot (annual limit of 2.4 million yen). The lifetime tax-free holding limit is 18 million yen (of which up to 12 million yen may be in the Growth Investment Slot), and the tax-free holding period is indefinite. Compared to the old NISA (General NISA: 1.2 million yen annually for 5 years; Tsumitate NISA: 400,000 yen annually for 20 years), the major changes are a substantial expansion of investment limits and permanent availability. According to data published by the Financial Services Agency, new NISA accounts reached approximately 23 million by the end of June 2024, with cumulative purchases of around 10 trillion yen.
Products Eligible for the Growth Investment Slot
The Growth Investment Slot allows purchases of listed stocks (Japanese and foreign), ETFs, REITs, and investment trusts. However, stocks under delisting or surveillance designation, investment trusts with trust periods under 20 years, monthly-distribution funds, and leveraged or inverse ETFs are excluded. From an individual stock perspective, virtually all stocks listed on TSE Prime, Standard, and Growth markets (excluding delisting/surveillance names) are eligible, meaning nearly every listed equity can be held tax-free. Foreign stocks are also eligible, but foreign withholding tax on dividends is not covered by the tax exemption - for US stocks, the 10% US withholding tax still applies.
Tax-Free Benefits for Individual Stock Investing
In a standard taxable account, dividends and capital gains are taxed at 20.315%. Individual stocks held in the Growth Investment Slot are exempt from this tax, so for a stock with a 4% dividend yield, approximately 0.8% of annual tax burden disappears. Filling the 2.4 million yen slot with 4%-yielding stocks produces annual dividends of 96,000 yen received in full, a tax saving of approximately 19,500 yen per year compared to a taxable account. Capital gains are similarly exempt - a 1 million yen profit saves roughly 200,000 yen in tax. Placing long-term holdings with growing dividends in the Growth Investment Slot amplifies the tax-free benefit year after year.
Slot Recycling and Considerations When Selling
Under the new NISA, selling a holding restores the acquisition-cost portion of the slot in the following year (book-value basis). For example, selling a stock purchased for 1 million yen at 1.5 million yen restores 1 million yen of slot capacity the next year. This enables a strategy of taking profits and rotating into different names, though annual new purchases cannot exceed 2.4 million yen. Importantly, losses cannot be offset against gains in taxable accounts, and loss carryforward does not apply. Placing high-volatility stocks in NISA therefore means no tax relief if losses occur.
Combining with the Tsumitate Slot and an Exit Strategy
The Growth Investment Slot (2.4 million yen/year) and the Tsumitate Slot (1.2 million yen/year) can be used together, for up to 3.6 million yen of tax-free investment per year. A common division is to build core assets by accumulating global equity or index funds in the Tsumitate Slot, while holding individual stocks, high-dividend names, or thematic ETFs as satellites in the Growth Investment Slot. The exit (selling) approach deserves attention: because the tax-free holding period is now indefinite, there is no need to sell in a hurry, and holding long term while receiving dividends tax-free becomes rational. Since the slot is restored on a book-value basis the following year, you can draw down in a planned way around life events such as housing or education and redirect the freed capacity into reinvestment. Because the tax-free benefit compounds with longer holding periods, the scheme suits long-term holding better than frequent trading. Note that the tax-free allowance cannot be transferred to another person or account, and one account per person is the rule. You may change financial institutions annually, but capacity purchased that year cannot be transferred, so choosing where to open the account based on product lineup and fees pays off over the long run.
Practical Considerations for the Growth Investment Slot
Several practical points merit attention when using the Growth Investment Slot for individual stocks. First, the dividend receipt method must be set to 'proportional distribution by number of shares' - otherwise the NISA tax exemption does not apply (post-office or bank-account receipt methods are taxed). Second, if the same stock is held in both NISA and a taxable account, you must specify which account to sell from. Third, the annual 2.4 million yen limit resets on January 1, so there is no need to rush to fill it by year-end, though unused capacity does not carry over.
