What Is Sub Brokerage? Why Should You Consider Overseas Investing?

In Taiwan, many investors are turning their attention to overseas markets, eager to participate in global economic growth, but opening accounts overseas directly often involves complex procedures and language barriers. This is where “sub brokerage” becomes the bridge connecting domestic and international markets.

Definition and Operating Mechanism of Sub Brokerage

In simple terms, “sub brokerage” means that you entrust the buying and selling of overseas securities to a domestic brokerage firm, which then re brokers the orders to its overseas partner brokerage firm to complete the transaction. Imagine clicking your mouse in Taiwan to buy Apple shares listed in the US, or a popular ETF listed in Japan. All of this is achieved through the professional services of a domestic brokerage firm.

This operating mechanism can be broadly divided into several stages:

• Principal (You): Place buy or sell instructions for overseas stocks or funds with a domestic brokerage firm.
• Domestic brokerage firm: Receives your instructions and forwards them to its overseas partner brokerage firm. At the same time, the domestic brokerage firm handles fund remittances, clearing and settlement, and tax statement preparation, greatly reducing operational complexity for you.
• Overseas partner brokerage firm: Executes your trading instructions in the overseas market.
• Overseas market: The actual venue where trades take place (such as the New York Stock Exchange or Nasdaq).

This layered delegation structure allows Taiwanese investors to participate in international markets legally and conveniently, without directly dealing with the complexities of overseas account opening and regulations. For investors who want to understand how to use sub brokerage, grasping this mechanism is the first step.

Three Key Advantages and Potential Risks of Investing via Sub Brokerage

Investing overseas through sub brokerage indeed brings significant convenience and opportunities, but it also comes with certain potential risks. As an experienced investor, I would remind you to fully understand both aspects.

⭐ Three Key Advantages ⭐

1. Participate in global economic growth and diversify portfolio risk: Taiwan’s market is limited in scale. Through sub brokerage, you can allocate funds to leading industries and top companies worldwide, such as US technology giants, innovative industries in Japanese stocks, or European luxury brands. This not only broadens your investment horizon, but also effectively diversifies the risks of a single market or a single industry, making your portfolio more resilient. This is also why many people actively seek to complete the sub brokerage activation process.
2. Convenient trading channel and a familiar domestic brokerage interface: For investors who are already accustomed to Taiwanese brokerage trading interfaces, the greatest advantage of sub brokerage is that you do not need to readjust to unfamiliar overseas trading platforms. Most domestic brokerage firms provide a sub brokerage order placement interface similar to their Taiwan stock trading platforms, allowing you to get started quickly and reduce learning costs. From quote inquiries and order placement to checking transaction records, everything can be completed in a familiar environment, greatly enhancing convenience.
3. Domestic brokerage firms assist with tax and settlement matters: The most troublesome aspect of overseas investing is often taxation. Through sub brokerage, domestic brokerage firms help you handle clearing and settlement for overseas trades, dividend distributions, and may even provide annual transaction statements and reference materials for overseas income tax filing. This service saves you significant time and effort, allowing you to focus more on investment decisions without worrying about complex tax filing issues.

🚨 Potential Risks 🚨

• Exchange rate risk: Investing in overseas markets requires foreign currency exchange. Whether the New Taiwan dollar appreciates or depreciates will affect your investment returns, making this an important aspect of sub brokerage investing that cannot be overlooked.
• Market volatility risk: Overseas markets may experience sharp volatility due to international political and economic events, sometimes to a greater extent than a single regional market.
• Trading cost considerations: Compared with opening an account directly with an overseas brokerage firm, sub brokerage typically involves two layers of brokerage services, so fees and related charges are usually higher. Before applying for a sub brokerage account, be sure to carefully compare the fee standards of different brokerage firms.

2026 Complete Sub Brokerage Account Opening Process and Required Documents for Account Application

After deciding to enter overseas markets, the next key step is how to “activate sub brokerage”. This process is actually simpler than you might think. As long as you follow the steps, you can complete the sub brokerage account application quickly.

Step by Step Guide to Opening a Sub Brokerage Account in Five Steps

1. Choose a suitable brokerage firm: First, you need to select a domestic brokerage firm that offers sub brokerage services. Key considerations include commission rates, the markets and product types available for investment (such as US stocks, Hong Kong stocks, Japanese stocks, ETFs), platform stability, and customer service quality. It is recommended that you compare multiple providers to find the brokerage firm that best fits your needs.
2. Prepare complete account opening documents: Usually, you will need to prepare the following:
   • National ID card original
   • Secondary identification document (such as a health insurance card or driver’s license)
   • Seal (which some brokerage firms allow you to replace with a signature)
   • A “TWD settlement account” and a “foreign currency deposit account” opened at a domestic bank (for overseas trading fund transfers).
3. Complete the sub brokerage application form and sign the relevant documents: You will need to complete a “designated money trust agreement for investing in overseas stocks and other securities” (or a similarly named document) as well as a risk disclosure statement and a basic client information form. These documents explain in detail the rights, obligations, and risks of sub brokerage. Be sure to read them carefully before signing.
4. Open a foreign currency deposit account: Because overseas stock trading involves foreign currency, you need a designated foreign currency deposit account to deposit foreign currency funds for trading and to receive overseas dividends or sale proceeds. This account is usually opened at a partner bank designated by your chosen brokerage firm.
5. Deposit trading funds: After completing all document signing and account opening steps, you need to deposit the funds you plan to invest (in foreign currency) into your foreign currency deposit account, and then you can proceed to the next step of sub brokerage order placement instruction.

These five steps are the key steps for applying for a sub brokerage account. Completing them in order will allow you to successfully open the door to overseas investing.

Comparison of Online and Offline Application Methods

With the development of financial technology, there are now more ways to apply for a sub brokerage account. The main options are online and offline:

• 💻 Online Application: Convenient and Fast, Saving Time and Effort
  • Advantages: You can complete the application from home via a computer or mobile phone, saving commuting and waiting time. Many brokerage firms offer digital signing services, making the process smoother. For investors familiar with online operations, this is undoubtedly the most efficient option, especially if you want to quickly understand how sub brokerage works and take action immediately.
  • Suitable for: Investors with basic digital operation skills, limited time, and a certain level of understanding of the brokerage firm’s services.
• 🏢 Offline Application: Dedicated Assistance and Immediate Answers
  • Advantages: By visiting the brokerage firm in person, you can receive one on one consultation from a representative. For investors who are unfamiliar with the process, have many questions, or prefer face to face communication, this method provides greater peace of mind and allows all concerns regarding sub brokerage account application to be addressed immediately.
  • Suitable for: Investors new to overseas investing, unfamiliar with the process, or those who require professional explanation.

Both methods have their own advantages. You can choose based on your needs and habits. Regardless of the method, be sure to confirm that all documents are accurate and complete.

Sub Brokerage Order Placement Tutorial: A Practical Walkthrough From Login to Trade Completion

After successfully completing your sub brokerage account application, the most anticipated step is placing actual trades. Below is a detailed sub brokerage order placement tutorial to help you understand how to trade in overseas markets.

Understanding the Order Interface and Common Function Buttons

After logging in to the sub brokerage trading platform provided by your brokerage firm, (usually a dedicated app or web version), you will see an integrated interface. While layouts may vary slightly among brokerage firms, the core functions are largely the same:

• Quote section: Displays real time prices, price changes, and trading volume for overseas stocks or ETFs you are following. You can search for different overseas instruments here.
• Account information section: Shows your available funds (in foreign currency), current holdings, and total asset value. This is key to keeping track of your investment status at all times.
• Order placement section: This is the core area where you enter trading instructions. It usually includes:
  • Product code or name: Enter the stock symbol or name you wish to trade.
  • Trade direction: Select “buy” or “sell”.
  • Trade quantity: Enter the number of shares or units you want to buy or sell.
  • Trade price: Choose “market order”, “limit order”, or “other order types”.
  • Order validity: Set the validity period of the order (such as valid for the day or until canceled).
• Order inquiry or history: View all submitted but unfilled orders, as well as past execution records.

Becoming familiar with these basic functions is an essential prerequisite for completing the sub brokerage order placement tutorial. It is recommended that you spend some time exploring the interface before placing actual orders to understand the function of each section.

How to Place Orders via Sub Brokerage: Explanation of Common Trading Instructions

After understanding the interface, the next step is to place actual sub brokerage orders. Below are several common trading instructions to help you apply them flexibly according to market conditions:

1. Market Order: The Preferred Choice for Fast Execution
   • Features: Executes immediately at the best available market price.
   • Applicable scenarios: Used when you want to complete a trade quickly and do not mind small price differences, such as when sudden positive or negative news prompts you to enter or exit the market immediately.
   • Points to note: During periods of high market volatility, the actual execution price may differ significantly from the price you see.
2. Limit Order: A Tool for Precise Price Control
   • Features: You specify a buy or sell price. Buy orders will only execute at or below your specified price, while sell orders will only execute at or above your specified price.
   • Applicable scenarios: Used when you have a clear target price in mind, or when you want to buy undervalued assets or sell overvalued assets at specific price levels.
   • Points to note: If the market price does not reach your specified level, the order may not be executed.
3. Stop Loss Order: A Line of Defense for Asset Protection
   • Features: You set a “stop loss price”. When the market price reaches or falls below this price, the stop loss order is triggered and automatically submitted as a market order or limit order to reduce potential losses.
   • Applicable scenarios: Used to control risk and prevent excessive losses to your portfolio, such as setting a reasonable stop loss point after purchasing a stock.
   • Points to note: In rapidly falling markets, the actual execution price of a market stop loss order may differ from the trigger price due to slippage”.
4. Take Profit Order: A Helper for Locking in Gains
   • Features: You set a “take profit price”. When the market price reaches or rises above this price, the take profit order is triggered and automatically submitted as a market order or limit order to lock in realized gains.
   • Applicable scenarios: Used when you have a predefined profit target and want to exit automatically once the target is reached.
   • Points to note: If the market rises rapidly and then falls without touching the take profit price, you may miss the opportunity to realize gains.

Before placing any sub brokerage order, be sure to double check the product code, buy or sell direction, quantity, price, and currency. Beginners are advised to start with small test trades to become familiar with the entire sub brokerage order placement process and gradually build confidence. Prudent operation is the key to successful overseas investing.

FAQ

Q: What Fees Are Included in Sub Brokerage?

A: The main fees for sub brokerage typically include trading fees (calculated as a percentage of the transaction amount and usually subject to a minimum charge threshold), remittance fees (for transferring funds from a TWD account into a foreign currency account or to an overseas brokerage firm), custody fees (which some brokerage firms charge on held assets) and other potential miscellaneous fees such as dividend processing fees. Fee standards vary among brokerage firms. It is recommended that you compare carefully before opening an account and read the fee disclosures in detail.

Q: Is There a Minimum Investment Amount Requirement for Sub Brokerage?

A: Yes. Most domestic brokerage firms’ sub brokerage services set a minimum investment amount requirement. This requirement can range from several hundred US dollars to several thousand US dollars, and it varies depending on the brokerage firm you choose, the market, and the product category you trade. For example, buying one share of a US stock may cost only tens of US dollars, but if there is a minimum fee or an initial deposit threshold, the effective amount you need to invest will be higher. It is recommended that you confirm with your target brokerage firm before applying for a sub brokerage account.

Q: How Are Sub Brokerage Profits Taxed?

A: Profits from sub brokerage investments are classified as “overseas income” and are subject to Taiwan’s “alternative minimum tax system” (also known as the basic tax amount). Under current regulations, if an individual’s annual total overseas income reaches TWD 1,000,000 or more, it must be combined with other items included in basic income for calculation. After deducting the TWD 6,700,000 exemption, if the remaining amount exceeds the taxable threshold, basic tax must be declared and paid. This is a relatively complex tax issue. It is recommended that you refer to the latest information on the Ministry of Finance Tax Portal, or consult a professional accountant for planning (such as the Ministry of Finance website).

Q: Are Sub Brokerage Trading Hours the Same as Taiwan’s Stock Market?

A: No. Sub brokerage trading hours follow the local trading hours of the overseas market you invest in. For example, if you invest in US stocks, trading hours follow US market opening and closing times, and you must consider the time difference under daylight saving time and standard time. This means you may need to trade late at night or early in the morning Taiwan time, or place pending orders in advance. Be sure to confirm the target market’s trading hours before placing orders.

Q: Can I Invest in All Overseas Market Products Through Sub Brokerage?

A: Usually not. Sub brokerage services offered by domestic brokerage firms will limit the investable markets and product types based on their overseas partners and their own risk control considerations. Common investable products include US stocks (including individual stocks and ETFs), Hong Kong stocks, Japanese stocks, overseas bonds, and overseas funds. However, some more niche overseas market products or those with low liquidity may not be tradable via sub brokerage. Therefore, when applying for a sub brokerage account, be sure to confirm whether the brokerage firm’s product coverage matches your investment plan.
