Why Non-U.S. Investors Should Use UCITS ETFs to Invest in the Nasdaq 100

Reply from Teacher CLEC James

Many students ask me:

Teacher, I am not American, and I do not live in the United States.

Why do you keep reminding me, "Do not buy U.S.-registered ETFs directly"?

There is really only one reason, and it is extremely important:

U.S. estate tax.

When non-U.S. persons open accounts with many U.S. brokers, there can be U.S. estate-tax inheritance-procedure issues, and inheritance must be handled according to U.S. estate tax law.

Many online brokers are securities firms registered in the United States. They must be regulated under U.S. law, and inheritance is also handled under U.S. law. For non-U.S. persons, only USD 60,000 of U.S. assets is exempt; the excess is subject to 40% estate tax. This has nothing to do with the investment target you bought.

Even if you buy an Ireland-issued fund, if the account is regulated by the U.S. Securities and Exchange Commission, it still has to go through the inheritance rules under U.S. estate tax law.

Your heirs may need to obtain documents proving their inheritance rights, have them notarized by a local court, translate them into English, then have them notarized at the local U.S. diplomatic mission before the inheritance process can begin.

The U.S. inheritance process is very complicated. You need to hire a lawyer and go through probate. It usually takes six months to more than a year to complete. Many estates of non-U.S. persons are ultimately abandoned because the process is far too complicated and lawyer fees are also very expensive.

For example, IBKR; Futu's international brand is Moomoo, and its U.S. business is operated by Moomoo Financial Inc., a broker registered with the SEC and regulated by FINRA; Tiger Brokers' U.S. entity is US Tiger Securities, Inc., which is likewise an SEC-registered broker. [1, 2, 3, 4, 5, 6]

The following are several other major international and Asian online brokers registered with the U.S. Securities and Exchange Commission:

Interactive Brokers (IBKR): A globally known online broker with a large business presence in Asia. It is a U.S.-registered broker and is strictly regulated by the SEC and FINRA. [1]

Firstrade: An online broker favored by U.S. investors. It is registered with the SEC and is a FINRA/SIPC member. [1]

Charles Schwab: A global financial institution headquartered in the United States, with multiple offices and service centers in Asia, regulated by the SEC and FINRA.

Taiwan's sub-brokerage arrangement currently does not have a U.S. estate-tax issue. Sub-brokerage accounts are registered in U.S. financial accounts under the bank's name, not under the Taiwanese investor's name.

So not only should you not casually buy U.S. funds, you also should not open an account with a broker registered in the United States.

1. The biggest hidden risk for non-U.S. persons: the U.S. estate-tax exemption is only USD 60,000

As long as you are a non-U.S. tax resident (NRA),

but you hold U.S. Situs Assets, such as:

• QQQ, SPY, VOO

• U.S. stocks

• U.S. REIT

then if an accident happens:

👉 The portion above USD 60,000 may be subject to U.S. estate tax of up to 40%.

This is not a problem of investment return.

It is a structural mistake that can destroy family assets in one event.

⸻

2. Skilled investors are not avoiding the U.S.; they are "switching to a different legal structure"

What truly mature long-term investors do is this:

Use "non-U.S.-registered" ETFs to keep investing in the best U.S. companies.

Therefore, a large number of non-U.S. investors around the world choose:

UCITS ETFs registered in Ireland or Luxembourg.

These ETFs:

• Still track the Nasdaq 100

• But are legally Non-U.S. Situs

• Are completely excluded from U.S. estate tax

The returns still come from U.S. technology giants,

but the estate-tax risk is reduced to zero.

⸻

3. What is UCITS? Why are these five letters so important?

As long as "UCITS" appears in the ETF name, it means:

• It is regulated at the highest level in the EU

• It is usually registered in Ireland

• For non-U.S. persons, it is not a U.S. asset

👉 Whether UCITS is present determines whether you may be subject to U.S. estate tax in the future.

⸻

4. The most mainstream Nasdaq 100 UCITS ETFs in 2025

(1) Invesco EQQQ Nasdaq-100 UCITS ETF (Ireland)

• One of Europe's longest-standing Nasdaq UCITS ETFs

• Good liquidity and a mature market

Version distinctions:

• EQQQ: distributing

• EQAC / EQQS: accumulating (automatic compounding)

XNAS refers to the Xtrackers NASDAQ 100 UCITS ETF 1C exchange-traded fund (ETF), issued by the globally known asset management company

DWS (part of Deutsche Bank Group), tracking the Nasdaq 100 Index (NASDAQ100).

On IB there is also a USD-denominated option. Choose the one ending in LSEETF; it is currently about USD 60 per share.

Its asset size is about USD 1.9 billion, smaller than CNDX; its management fee is 0.2%, better than CNDX. So you can evaluate it yourself.

I compared the returns of CNDX/ EQAC/ XNAS. Their performance is all similar, with each having strengths in different periods.

⸻

(2) [Top choice] iShares NASDAQ 100 UCITS ETF (BlackRock)

If you ask me:

Teacher, if I can choose only one fund in 2025, which one should it be?

The answer is this one.

The reason is simple:

• Largest scale

• Strongest liquidity

• Registered in Ireland

• Accumulating, with the cleanest tax handling

Key information:

• Domicile: Ireland

• TER: about 0.33%

• AUM: about USD 16.2 billion

• ISIN: IE00B53SZB19

Common tickers:

• CNDX (London Stock Exchange, USD)

• SXRV (Germany Xetra, EUR)

⸻

5. Accumulating vs. distributing: how should you choose?

I will give the conclusion directly:

• Asset accumulation stage, long-term investors → accumulating (CNDX)

• Need cash flow → only then consider distributing

The biggest advantages of accumulating funds are:

• No dividends paid out

• No dividend tax generated

• Returns are reflected directly in the NAV

👉 For long-term wealth building, this is the most efficient.

⸻

6. Practical reminder: buying European ETFs through a U.S. broker

Using IBKR as an example:

• You need to enable LSE or Xetra trading permissions

• This is not a U.S. stock; it is a Europe-listed ETF

• The currency may be USD or EUR

The technical issues are not difficult.

What is truly difficult is the mindset.

⸻

7. The teacher's one-sentence summary

The biggest risk in investing

has never been market volatility,

but choosing the wrong system from the beginning.

You do not need to give up investing in the United States.

You only need to use UCITS ETFs

to keep the returns and keep the risk outside.

Why should "non-U.S. investors" avoid U.S.-registered ETFs?

-- From the risk of U.S. estate tax to the key value of Ireland UCITS Nasdaq 100 ETFs

Many investors think that as long as they do not live in the United States, they do not need to worry about U.S. tax issues.

This is a very dangerous and extremely costly misunderstanding.

For non-U.S. tax residents (NRA, Non-Resident Alien), as long as you hold U.S. Situs Assets, even if you are not in the United States and are not a U.S. citizen, you can still be subject to U.S. estate tax.

The cruelest key point is here:

The U.S. estate-tax exemption for NRAs is only USD 60,000.

In other words, as long as you hold the following through a U.S. broker:

• U.S.-registered ETFs (such as QQQ, SPY, VOO)

• U.S. stocks

• U.S. REITs

Once an unexpected accident occurs, the portion above USD 60,000 may face estate tax of up to 40%.

⸻

The solution is not to stop investing, but to "change the structure"

Truly smart and mature long-term investors do not avoid the U.S. market because of risk. They invest through the correct legal structure.

Therefore, a large number of non-U.S. investors around the world choose:

UCITS ETFs registered in "Ireland or Luxembourg"

These ETFs:

• Still track U.S. indexes (such as the Nasdaq 100)

• But legally, they are not U.S. Situs Assets (Non-U.S. Situs)

• Are completely outside the scope of U.S. estate tax

Investment returns still come from U.S. technology giants,

but the estate-tax risk is "zero."

⸻

What is UCITS? Why is it the key to tax avoidance?

UCITS (Undertakings for Collective Investment in Transferable Securities)

is the EU's highest-level and strictest fund regulatory framework.

As long as an ETF name clearly includes "UCITS", it means:

• It is regulated by EU rules

• Its domicile is usually Ireland or Luxembourg

• For non-U.S. investors, it is not a U.S. asset

👉 These five letters are the dividing line for whether U.S. estate tax may apply.

⸻

The most mainstream "non-U.S.-registered" Nasdaq 100 UCITS ETFs in 2025

1. Invesco EQQQ Nasdaq-100 UCITS ETF (Ireland)

This is one of the oldest Nasdaq 100 UCITS ETFs in Europe.

Features:

• Domicile: Ireland

• High liquidity, listed for many years

• Suitable for investors who prefer "receiving dividends" or "automatic compounding"

Common versions:

• EQQQ: Distributing

• EQAC / EQQS: Accumulating, automatic compounding

⸻

2. iShares NASDAQ 100 UCITS ETF (BlackRock, Ireland)

This is the Nasdaq 100 UCITS ETF that I rank as the top choice for non-U.S. investors in 2025.

Why is it the top choice?

Because it has four key conditions at the same time:

1. Largest assets under management (AUM)

2. Strongest global liquidity

3. Registered in Ireland, completely avoiding U.S. estate tax

4. Accumulating structure, with no dividend-tax trouble

Key parameters (2025):

• Domicile: Ireland

• TER (management fee): 0.33% / year

• AUM: about USD 16.2 billion

• ISIN: IE00B53SZB19

Mainstream tickers:

• CNDX (London Stock Exchange, USD settlement, best liquidity)

• SXRV (Germany Xetra, EUR settlement)

⸻

"Accumulating" vs. "Distributing": how should you choose?

This is not a question of good or bad. It is a choice about tax efficiency and life stage.

Accumulating

• Dividends are automatically rolled into the NAV

• No cash is paid out

• Best suited for long-term investing and the asset-growth stage

• Example: CNDX

Distributing

• Pays dividends regularly

• Suitable for people who need cash flow

• But pay attention to dividend-tax issues in each country

• Example: EQQQ

👉 If your goal is "long-term wealth building and maximizing assets," accumulating is usually the more efficient choice.

⸻

Practical reminder: what should you watch when buying European ETFs through a U.S. broker?

Using IBKR (Interactive Brokers) as an example:

1. You must enable trading permissions for the corresponding markets

• For example: London Stock Exchange (LSE), Germany Xetra

2. The trading currency may be USD or EUR

3. This is not a U.S. stock ETF; it is a Europe-listed ETF

The technical threshold is not high, but the concept must be correct.

⸻

Conclusion: the real risk is not market volatility, but a structural error

Many people spend their whole lives studying:

• Entry points

• Technical chart patterns

• Short-term rises and falls

but ignore a structural risk that is enough to destroy family assets: the estate-tax structure.

You do not need to give up investing in the United States.

You only need to invest with the right tool and the right legal structure.

UCITS is not a speculation technique.

It is a basic skill of mature investors.

2025 Investment Guide: How can non-U.S. persons invest in Nasdaq 100 and legally avoid U.S. estate tax?

For non-U.S. tax residents (Non-Resident Alien, NRA) who are enthusiastic about investing in U.S. stocks, the biggest hidden risk is often not market volatility, but the tax rules of the U.S. Internal Revenue Service (IRS).

When foreigners hold U.S. Situs Assets, the estate-tax exemption is only USD 60,000. Once the total asset value exceeds this threshold, the excess may face estate tax of up to 40%. To avoid this risk, more and more investors choose "UCITS ETFs" registered in Ireland or Luxembourg to track U.S. stock indexes.

Although these ETFs track the Nasdaq 100 Index (Nasdaq 100), their legal structure makes them "Non-U.S. Situs" assets, so they are completely excluded from the scope of U.S. estate tax.

This article reviews the two most mainstream non-U.S.-registered Nasdaq 100 ETFs in 2025 and provides specific investment suggestions.

Mainstream market choices: the two leading UCITS ETFs

Among Nasdaq 100 ETFs registered in Ireland, Invesco and iShares (BlackRock) are the two issuers with the best liquidity and the highest trust in the market.

Top recommendation for 2025: iShares (CNDX)

If you already have an account with a U.S. stock broker (such as Interactive Brokers, IBKR) and want to invest in the Nasdaq Index through an Ireland-registered fund, then considering liquidity, asset size, and trading costs, the best choice in 2025 is:

iShares NASDAQ 100 UCITS ETF (Acc)

This is currently the Nasdaq 100 UCITS version with the strongest global liquidity and largest assets under management, especially suitable for large capital inflows and outflows.

Reasons for recommendation and key parameters

• Ticker: CNDX (London Stock Exchange, USD settlement)

• ISIN: IE00B53SZB19

• Domicile: Ireland -- enjoying tax treaty advantages.

• Total expense ratio (TER): 0.33% p.a.

• Other trading market: If holding EUR, you can choose SXRV on Germany's Xetra exchange.

Key decision before investing: accumulating vs. distributing

When choosing a specific target, you need to decide how dividends are handled. This directly affects your cash flow and tax treatment:

Practical operating guide

1. Identify the "UCITS" label:

When searching for a target, be sure to confirm that the ETF name contains "UCITS". This means the fund follows the EU regulatory framework (usually registered in Ireland), which is the core key to thoroughly avoiding U.S. estate-tax risk.

2. Broker permission settings:

Most U.S. domestic brokers (such as Firstrade, Schwab) do not provide trading in EU UCITS ETFs. You need to use an international broker, such as Interactive Brokers (IBKR).

• Operating tip: Before placing an order, make sure you have enabled stock trading permissions for European markets in the backend, such as the London Stock Exchange LSE - UK.

3. Trading currency selection:

It is recommended to prioritize USD-denominated tickers (such as CNDX). This can avoid extra foreign-exchange conversion losses during trading and connect seamlessly with your original U.S. stock capital pool.

Summary

In 2025, to protect asset inheritance and avoid U.S. estate tax, buying the Ireland-registered iShares NASDAQ 100 UCITS ETF (ticker: CNDX) is the best strategy combining liquidity, scale, and tax efficiency.
