0️⃣ Tax-Free up to 50 Million Won to Encourage Domestic Investment
📌 Up to 100% Tax Reduction for Early Returns…Aiming for Exchange Rate Stability
💬 The government announced a plan to exempt capital gains tax on up to 50 million won from foreign stock sales and provide additional tax benefits for long-term investment in domestic stocks. As the exchange rate recently surged to the 1,480 won range and the Korean won weakened, this measure aims to bring individual investor funds back from overseas to stabilize the foreign exchange market. Through a newly created "Return to Inland Market Account (RIA)", those who return in Q1 next year get 100% tax reduction, Q2 gets 80%, and the second half gets 50%. Additional income deductions are available when using currency hedging products. Dividends from overseas subsidiaries will be fully tax-exempt to encourage corporate foreign currency repatriation. The government plans to implement the related system from January next year to achieve early market stability.
1️⃣ Easy to Understand
As the exchange rate has recently surged, the government has urgently introduced a new policy. The core is simple: "If you sell foreign stocks and invest in Korean stocks, we won't charge you taxes." Let's understand step by step why this policy was created and what benefits it offers.
First, we need to understand why the government created this policy. Recently, the won-dollar exchange rate has soared to the 1,480 won range. When the exchange rate rises, it means the value of the Korean won is falling. You need 1,480 won to buy 1 dollar. Just last year it was in the 1,300 won range, so it has risen by 180 won.
One reason for the rising exchange rate is the increase in foreign stock investments by individual investors. In recent years, domestic individual investors called "westward ants" have been buying massive amounts of US stocks. This is because US big tech stocks like Tesla, Nvidia, and Apple have risen significantly.
The problem is that you need to convert Korean won to dollars to buy US stocks. Investors sell won and buy billions of dollars every month, so dollar demand increases and the exchange rate rises. Simply put, when many people want to buy dollars, the price of dollars (exchange rate) goes up.
When the exchange rate rises, various problems occur. Import prices go up. Things we eat like flour, oil, and natural gas mostly need to be bought with dollars, and when the exchange rate rises, it takes more won to buy the same goods. Overseas travel expenses also increase. Companies with foreign currency debt see their won-denominated debt amount increase, increasing their burden.
So the government wondered: "How can we bring the money that went overseas back to Korea?" The answer is this tax benefit.
What benefits are there? There are three main ones.
First, capital gains tax exemption on foreign stocks. Originally, if you sell foreign stocks and make a profit, you have to pay taxes. After deducting 2.5 million won, you pay 22% (including local taxes) tax on the remaining profit. For example, if you made 30 million won profit from US stocks, after subtracting 2.5 million won, you would have to pay about 6.05 million won tax on 27.5 million won, which is 22%.
But under the new system, you don't have to pay this tax on up to 50 million won. However, there are conditions. You must put the money from selling foreign stocks into a special account called "Return to Inland Market Account (RIA)" and invest it in Korean stocks for at least 1 year.
The better point is that the earlier you return, the bigger the benefits. If you return in Q1 next year (January-March), you get 100% full exemption. You don't have to pay even 1 won of the 6.05 million won tax on 30 million won profit. If you return in Q2 (April-June), you get 80% exemption so you only pay 1.21 million won. If you return in the second half (July-December), you get 50% exemption so you pay 3.02 million won.
Let's look at an example. Mr. A bought Tesla stock last year and sold it this year. He made a profit of 30 million won. Normally he would have to pay 6.05 million won in taxes. But if Mr. A sells his Tesla stock in February next year, puts that money into an RIA account, and holds Korean stocks like Samsung Electronics or Naver for more than 1 year, he doesn't have to pay any tax. He saves 6.05 million won.
Second, additional benefits when using currency hedging products. Currency hedging is a financial product that prevents losses from exchange rate fluctuations. For example, if the exchange rate is 1,480 won now but you're worried it might fall to 1,300 won later, you can use a currency hedging product to lock in the exchange rate in advance.
The government said it will provide additional income deductions if individual investors use currency hedging products. The exact amount hasn't been announced yet, but you can reduce exchange rate fluctuation risk while also receiving tax benefits.
Third, tax exemption on corporate overseas dividends. This is a measure for companies, not individuals. Many Korean companies have subsidiaries overseas. Like Samsung Electronics' US office or Hyundai Motor's European factories. When these subsidiaries make profits, they give dividends to headquarters.
Originally, taxes were charged on these dividends too. But now, instead of 95%, 100% of the full amount is treated as non-taxable income. Simply put, it means no taxes are charged. This is to encourage companies to bring dollars that were tied up overseas to Korea.
Why was this policy necessary? There are three reasons.
First, exchange rate stability. When individual investors sell foreign stocks and buy Korean stocks, a flow of selling dollars and buying won occurs. When this happens, dollar demand decreases and the exchange rate falls. This is the effect the government wants most.
Second, activating the domestic stock market. Recently, KOSPI has been struggling around the 2,400 level. Foreigners are also selling Korean stocks. As individual investors also flee overseas, the market becomes even more depressed. If individual funds return through this policy, stock prices can rise and the market can revive.
Third, preventing capital outflow. If overseas investment continues to increase, foreign currency flows out of Korea. Foreign exchange reserves decrease and financial instability can grow. Returning capital to Korea increases financial stability.
What will be the effect of this policy? In the short term, it will definitely help. Not paying taxes is a strong incentive. Especially for investors who made big profits from foreign stocks, the tax savings effect is large, so they're likely to switch to Korean stocks.
However, long-term effects are uncertain. First, what happens after 1 year? The RIA account condition is "holding domestic stocks for more than 1 year". After 1 year passes, it can flow out overseas again. It's not a fundamental solution.
Second, if the attractiveness of the Korean stock market itself doesn't improve, the effect will be limited. Investors bought US stocks because returns were good. Tax benefits alone are difficult to hold investors long-term. Fundamental improvements like corporate governance improvement, dividend expansion, and fostering innovative companies are needed.
Third, the exchange rate is determined by various factors. The exchange rate won't change much just from individual investor fund movements. Other factors like US interest rates, Korean economic growth rate, and trade balance are also important.
What should individual investors do? Three things need to be considered.
First, calculate the tax savings effect. If you made a lot of profit from foreign stocks, this benefit is significant. For example, the tax on 50 million won profit is about 11 million won, so if you don't have to pay this, it's a huge savings.
Second, evaluate the investment value of Korean stocks. It's not good to forcibly buy Korean stocks just because of taxes. Choose blue-chip stocks like Samsung Electronics, SK Hynix, Hyundai Motor or stocks with high growth potential.
Third, consider exchange rate fluctuations. Selling dollars and converting to won when the exchange rate is currently high can be advantageous. However, the exchange rate might rise further later, so keeping some as dollar assets is also a method.
Ultimately, this policy shows the government's will to stabilize the exchange rate while giving individual investors a choice. Whether to receive tax benefits or continue overseas investment is each person's judgment.
2️⃣ Economic Terms
📕 Capital Gains Tax
Capital gains tax is a tax imposed on profits from selling assets like stocks and real estate.
- For foreign stocks, a 22% tax rate (including local taxes) applies after deducting 2.5 million won annually.
- Domestic stocks have no capital gains tax unless you're a major shareholder, but foreign stocks are taxed for all investors.
- Through this measure, you can get exemption from this tax within a 50 million won limit.
📕 Currency Hedging
Currency hedging is a financial transaction that locks in exchange rates in advance or compensates for profits to prevent losses from exchange rate fluctuations.
- For example, if the exchange rate is 1,480 won now but you're worried it might fall to 1,300 won in 1 year, you can lock in 1,480 won in advance through hedging.
- Currency hedging products are implemented through derivatives like currency forwards, currency options, and currency swaps.
- The government encourages individuals to use currency hedging products by providing additional income deductions to contribute to foreign exchange market stability.
📕 Non-Taxable Income (Exclusion from Taxable Income)
Non-taxable income is a tax treatment that excludes part of a corporation's income from taxation.
- If a company treats dividends received from overseas subsidiaries as non-taxable income, it doesn't pay taxes on those dividends.
- Originally only 95% was non-taxable income, but this has been expanded to 100%.
- This increases incentives for companies to bring dollars that were tied up overseas to Korea.
📕 Return to Inland Market Account (RIA)
The Return to Inland Market Account is a special account newly created to repatriate overseas assets to Korea.
- If you put money from selling foreign stocks into this account and invest in domestic stocks for more than 1 year, you receive capital gains tax benefits.
- Larger exemption rates are provided to early returners to encourage fast fund repatriation.
- It is scheduled to be implemented from January 2025.
3️⃣ Principles and Economic Outlook
✅ Tax Incentives Change Fund Flows
Tax benefits are the most powerful policy tool to change investor behavior, with significant effects in inducing fund movements.
First, tax burden is a core factor in investment decisions. Investors look at not just returns but after-tax returns. Even if you make 30 million won profit from foreign stocks, if you pay 6 million won in taxes, the actual money in your hand is 24 million won. But if you don't pay taxes, you can keep all 30 million won. A 20% difference is enough to change investment decisions. In the past, when the government created tax-benefited products like ISA (Individual Savings Account) and pension savings, funds flooded in.
Second, early return incentives put out urgent fires. The tiered structure of 100% exemption in Q1 next year, 80% in Q2, and 50% in the second half makes investors move quickly. This uses the "loss aversion psychology" from behavioral economics. When people think "I'll lose out if I don't do it now," they take action. The government wants to create a flow of selling dollars and converting to won right now when the exchange rate is high.
Third, selling overseas assets increases dollar supply. When individual investors sell US stocks, they receive dollars. In the process of converting these dollars to won, dollars are supplied to the foreign exchange market. When dollar supply increases, the price of dollars (exchange rate) falls. If tens of trillions of won in funds move, it can have a real impact on the exchange rate. Inducing voluntary movement of private funds has fewer side effects than direct government intervention in the foreign exchange market.
Tax incentives are highly effective in the short term, but market fundamentals are more important in the long term.
✅ Preventing Capital Outflow and Defending the Exchange Rate
Increased overseas investment leads to capital outflow, which can lead to rising exchange rates and financial instability.
First, overseas investment by "westward ants" is a structural flow. Since 2020, the net purchase amount of overseas stocks by domestic individual investors has exploded. The cause was liquidity expansion after COVID and high returns from US stocks. Seeing Tesla rise 10 times and Nvidia rise 20 times, many people jumped into overseas investment. As of 2024, domestic investors' holdings of overseas stocks exceeded 100 trillion won. If this money continues to increase, dollar demand also continues to increase, increasing upward pressure on the exchange rate.
Second, exchange rate surges have negative effects on the overall economy. When the exchange rate rises from 1,300 won to 1,480 won by 180 won, import prices rise by about 14%. When raw material prices like flour, oil, and natural gas rise, living prices like bread, instant noodles, and electricity bills rise. When inflation rises, the Bank of Korea must raise interest rates, and when interest rates rise, the interest burden on companies and households increases. Companies with foreign currency debt see their won-denominated debt increase, intensifying their burden. Exchange rate surges are a destabilizing factor for the entire economy.
Third, capital repatriation policy is a temporary solution. Through this policy, funds can return in the short term, but they can flow out again after 1 year. This is because the RIA account's holding obligation period is 1 year. Fundamentally, the attractiveness of the Korean stock market must be increased. Companies must increase dividends, improve governance structures, and many innovative companies must be listed for investors to prefer the Korean market. If Samsung Electronics or Naver grow as much as Apple or Google, investors have no reason to go overseas.
To prevent capital outflow, not only tax benefits but also market structure improvements are needed.
✅ Promoting Corporate Overseas Profit Repatriation
If companies are encouraged to bring profits earned overseas to Korea, there are effects of foreign exchange market stability and investment expansion.
First, Korean companies hold massive assets overseas. Overseas subsidiaries like Samsung Electronics' US office, Hyundai Motor's European factories, and POSCO's Indian steel mill make large profits every year. When sending these profits to headquarters as dividends, if there's a tax burden, they often just leave it overseas. They reinvest in the US or use it locally. But if they don't charge taxes, the incentive to bring it to headquarters increases.
Second, dividend repatriation supplies dollars to the foreign exchange market. When overseas subsidiaries send dividends to headquarters, dollars (or other foreign currency) come to Korea. When companies convert these dollars to won, dollar supply in the foreign exchange market increases and the exchange rate falls. It's the same effect as individual investor repatriation. Especially because large companies' dividend amounts are large, the impact on the exchange rate can be significant.
Third, it can lead to domestic investment and employment expansion. When companies bring money earned overseas to Korea, it can be spent on R&D, factory construction, and employment expansion. Money that was tied up overseas invigorates the domestic economy. Of course, if companies only use this money for shareholder dividends, the effect is limited, but if it leads to investment, it contributes to economic growth in the long term.
Voluntary corporate dividend repatriation is a positive flow that contributes to foreign exchange market stability even without government intervention.
4️⃣ In Conclusion
The government's tax benefit policy is an emergency measure introduced during the exchange rate surge period. It exempts capital gains tax on up to 50 million won from foreign stock sales, gives up to 100% exemption benefits to early returners, and converts corporate overseas dividends to full tax exemption.
In the short term, there will definitely be effects. The strong incentive of tax savings changes investor behavior. Especially investors who made big profits from foreign stocks are likely to hurry to return in Q1 next year. If tens of trillions of won in funds move, it can have a positive impact on the exchange rate too.
However, long-term effects are uncertain. First, since the RIA account's holding obligation period is 1 year, it can flow out overseas again after that. Second, if the attractiveness of the Korean stock market itself doesn't improve, it's difficult to hold investors with tax benefits alone. Third, since the exchange rate is determined by various factors, it may not be completely stabilized just by fund repatriation.
For individual investors, it's an opportunity to choose. If you made a lot of profit from foreign stocks, it's a good opportunity to save taxes. However, it's not good to forcibly buy Korean stocks just because of taxes. You should choose blue-chip stocks like Samsung Electronics, SK Hynix, Hyundai Motor or stocks with high growth potential.
Companies also have increased incentives to bring overseas dividends to Korea. If these funds lead to domestic investment and employment expansion, it's positive for the entire economy.
The government plans to implement the related system from January next year, aiming for early market stability. For this policy to succeed, voluntary participation by investors is needed, and at the same time, structural improvement of the Korean stock market must be carried out in parallel.
Ultimately, this policy is an emergency prescription for exchange rate stability. There will be short-term effects, but in the long term, strengthening the fundamentals of the Korean economy and capital market is more important. Tax benefits are an opportunity, but investment decisions must be made carefully.
