Taiwan Sub-Brokerage 2026: 0.08% Fee War, 5 Brokers Compared

Introduction: See this 60 seconds before recommending a sub-brokerage

If you have decided to buy a US stock ETF (like VOO), the next question is usually: Which sub-brokerage should I open so that I don’t pay extra fees in vain?

This article directly compares major brokerages using the same standards, allowing you to first select a plan that “best suits your monthly deduction habits” before deciding whether to pursue the lowest rate.

Fee data as of 2026-10-14, checked against each brokerage’s official site. Promotions usually have expiry dates, so confirm on the official site before placing an order.

Quick answer: How to choose a sub-brokerage recommendation?

1. For small monthly amounts (under $100 USD), look at fixed low-fee DCA plans with a $10 minimum: SinoPac (USD $0.01 per order with foreign-currency debit) and Cathay ($0.10 per order). Capital and KGI DCA plans require at least NT$3,000 or US$100.
2. Focus on long-term compound interest efficiency, and prioritize DRIP function and ease of operation (SinoPac has a clear advantage).
3. If your monthly amount is high and irregular, compare one-off trade rates and minimums (SinoPac and Cathay at 0.08%; Cathay charges a flat $3 per ETF trade). Among DCA plans only Fubon charges a percentage (0.1%), which gets more expensive as the amount grows.
4. If you have not yet decided on an ETF target, first look at How to choose VOO, QQQ, and VT? and then come back to choose a brokerage, the decision will be faster.
5. If you want to start allocating directly, first use the ETF Beginner Allocation Toolkit to calculate the monthly investment amount and ETF ratio.

Why should novices start with “Sub-brokerage”? Understand overseas brokers vs. sub-brokers in seconds

Before buying US stocks, you will definitely hear about “sub-brokerage” and “overseas brokers”. They each have advantages and disadvantages, but I usually recommend novices to start with “sub-brokerage”.

When I was choosing, the first thing I cared about most was the handling fee, and the second was convenience. My salary transfer account happened to be with SinoPac, and they have been working hard to promote investment and savings in recent years, so using the brokerage of my salary transfer account is the most convenient for me. Although overseas brokers may have lower handling fees, I still choose sub-brokerage considering fund security and long-term convenience.

2026 fee war: lump-sum fees fall from 0.1x% to 0.08%

The biggest change in 2026: brokerages started a price war on regular lump-sum (non-DCA) trades.

SinoPac cut its online-order fee to 0.08% on January 1 (for monthly cumulative trades under US$50,000; anything above goes back to the standard rate). Cathay followed on January 6 with no amount cap and no minimum fee on online orders (promotion runs to 2026-12-31). Fubon charges new 2026 customers 0.06% for US whole-share trades on its AI PRO app (up to US$50,000 per month). In other words, the “SinoPac 0.12% is cheapest” line from my older posts is now history.

If you are buying VOO: Cathay’s official fee page lists US ETFs separately at a flat US$3 per trade for both buying and selling, not 0.08%. For a single VOO purchase below about US$3,750, US$3 costs more than 0.08% (US$1,000 would be 0.3%); it only pays off on larger trades. SinoPac’s ETF promotion is reported to require a separate application, with the lower of 0.08% or US$3 per trade applied. Check the official site for details.

⚠️ Rates change with promotions: the table above covers lump-sum trades, which follow different rules from the DCA plans below. Promotions come with expiry dates and conditions, so confirm the current plan on the official site before you open an account or place an order. For long-term investors, a 0.0x% gap matters far less than whether you can keep investing every month.

2026 Major Brokerage Sub-brokerage Program PK

Lump-sum trades are covered above. Back to what our lazy investors care about most, “fixed amount investment” (DCA). This follows a different set of rules: most brokerages charge a small flat fee instead of a percentage. Here are the SinoPac, Fubon, Cathay, Capital and KGI plans as of 2026-10-14:

懶大 (Lan Da)’s sincere words: How should investors with different budgets choose?

Whether you want to invest NT$3,000, NT$10,000 or NT$30,000 per month, I think the most important thing is always “convenience” and “being able to start”.

• If you are an extremely frugal small investor (less than $100 USD per month): SinoPac (USD $0.01 per order) or Cathay ($0.10 per order) DCA plans are the cheapest, both with a $10 minimum. Capital’s $0.03 per order is also low, but its minimum is $100.
• If you are an ultimate lazy person and value long-term compound interest: SinoPac’s exclusive “dividend reinvestment” function is irreplaceable.
• If you invest a higher or unfixed amount each month: if the amount is fixed, stay with a flat low-fee DCA plan, which gets cheaper as the amount grows; if it varies, use SinoPac or Cathay one-off trades at 0.08% (Cathay charges a flat $3 per ETF trade).

The compound interest magic of dividend reinvestment (DRIP): Why is this the key to lazy investment?

Like Buffett said, life is like a snowball, the important thing is to find wet snow and a long hillside. In investment, “dividends” are the snow that allows you to stick together, and “dividend reinvestment” is to roll this snow back onto your snowball to make it bigger and bigger.

If you spend the dividends you receive, the snowball will never grow. Let’s see how big the difference is in the long run if the dividends are reinvested:

Assumption: A single investment of $10,000 USD in VOO, with an annualized return of 12% and a dividend rate of 1.5%

This is a simplified estimate and does not consider tax factors

See the difference? Over 30 years, a small “dividend reinvestment” action can increase your assets by $100,000 USD! This is why I highly recommend SinoPac’s function.

Step-by-step tutorial: Taking SinoPac Securities as an example, how to set up a fixed amount investment in US stocks

It’s too empty to just talk without practice, here I will directly use the “SinoPac Securities” App (豐存股 (Feng Cun Gu)) as an example to teach you how to complete your first fixed amount investment setting in US stocks.

1. Login and Account Opening

   • First, you need to have an account with SinoPac Securities and have the sub-brokerage function enabled. If not, you can make an online appointment to open an account, which is very convenient.

2. Enter the “豐存股 (Feng Cun Gu)” Zone

   • Open the SinoPac Securities App, and you can usually find the entrance to “豐存股 (Feng Cun Gu)” on the homepage.

3. Select the US Stock Market and Search for Targets

   • After entering 豐存股 (Feng Cun Gu), select the “US Stock” market.
   • Enter the ETF code you want to invest in in the search box, such as “VOO”.

4. Set up your fixed amount investment plan

   • Select the deduction date: SinoPac provides 9 deduction dates per month, on the 3rd, 6th, 9th, 13th, 16th, 19th, 23rd, 26th, and 29th, which is very flexible.
   • Enter the deduction amount: You can choose to deduct in “NTD” or “USD”, with a minimum of $10 USD or NT$3,000 NTD.
   • Dividend Reinvestment: Be sure to check “Enable”! This is the key to making your snowball bigger and bigger.

5. Confirm and Submit

   • Check whether all settings are correct, confirm and submit, and you’re done! Next, the system will automatically buy assets for you on the date you specify, opening your lazy financial management path.

Choosing which sub-brokerage is like choosing a mobile phone plan, there is no absolute best, only the one that suits you best.

• If you are a small capital family and the monthly investment amount is not high, Cathay and SinoPac’s ultra-low buy-in handling fees are definitely your first choice.
• If you are an ultimate lazy person and hope to maximize asset compounding, then SinoPac’s exclusive “dividend reinvestment” function is a must for you.

The most important thing is always that step——“Take action”.

Instead of spending countless hours comparing the difference of a few decimal points in fees, it is better to choose one today, set up your fixed amount investment, and let your money start working for you. This is the true essence of “too lazy to get rich”!
