Imagine spending 20 years building a US$300,000 portfolio of Apple, Nvidia, Microsoft and S&P 500 ETFs.

You invest regularly, reinvest your dividends and watch your portfolio grow. You have a will, and your investments are held through a brokerage account in Singapore.

Then something unexpected happens.

What will your family actually inherit?

For Singapore investors, the answer may be more complicated than expected. While Singapore abolished estate duty in 2008, investments in US companies can still be subject to American estate tax.

And the tax rate can reach **40%**.

## Singapore Has No Estate Duty. The US Does.

Under US law, non-US citizens who are not domiciled in the US can be subject to estate tax on their US-situated assets.

These include shares of American companies such as Apple, Nvidia and Microsoft, as well as US-domiciled ETFs such as VOO, SPY and QQQ.

The important distinction is that **where your brokerage account is located does not necessarily determine where your investments are situated for tax purposes.**

You could hold US stocks through a Singapore brokerage and still have US estate-tax exposure.

For investors who are neither US citizens nor US-domiciled, the estate-tax filing threshold is just US$60,000 in US-situated assets, subject to the applicable filing rules.

**US$60k**

**40%**

That is substantially lower than the multimillion-dollar estate-tax exemption available to US citizens.

## How Much Could Your Family Owe?

US estate tax follows a progressive schedule, with rates reaching 40%.

But this does not mean every portfolio above US$60,000 automatically loses 40% of its value.

The calculation involves progressive tax brackets, available deductions and a tax credit, generally US$13,000 for a nonresident noncitizen without treaty relief.

Consider a simplified example of an investor with US$300,000 in US stocks at death.

Assuming the entire amount is taxable US-situated property, with no deductions, treaty relief or other adjustments, the estimated federal estate tax would be approximately US$74,800, or about a quarter of the portfolio.

That could leave around US$225,200 before other estate-administration expenses.

Less unified credit**–US$13,000**

Estimated estate tax**US$74,800**

Left for the family**US$225,200**

Simplified illustration: assumes all assets are taxable US-situated property, with no deductions, treaty relief or other adjustments, and excludes estate-administration costs. Based on the US federal estate-tax rate schedule.

The figures are illustrative, but they demonstrate why this is worth understanding well before an estate needs to be settled.

## What Happens to Your Brokerage Account When You Die?

One practical question is how the brokerage finds out.

A broker is not necessarily notified automatically when an account holder dies.

Usually, a family member, executor or surviving joint account holder must contact the brokerage and provide a death certificate.

The broker may then restrict trading and withdrawals while it establishes who has legal authority over the assets.

Depending on the account and jurisdiction, the executor may need to provide probate documents, identification, estate-tax forms and other supporting records.

For certain US assets, an IRS transfer certificate may also be required before the investments can be released or transferred.

This process can take months, sometimes longer.

And knowing someone’s login details does not give a surviving family member legal authority to trade or withdraw their investments after death.

The challenge is therefore not just how much tax may be payable. It is also how quickly and smoothly the family can access the assets.

## What You Can Do

Estate planning is not necessarily about avoiding US investments. It is about understanding how different investment structures affect both taxes and inheritance.

There are several options worth considering.

### 1\. Consider Ireland-Domiciled ETFs

For investors seeking broad US market exposure, Ireland-domiciled ETFs are one of the more accessible alternatives.

Take the S&P 500.

A Singapore investor could buy a US-domiciled ETF such as VOO, or an Ireland-domiciled ETF such as CSPX, which also tracks the S&P 500.

Although both provide exposure to American companies, their legal domiciles differ.

#### US-domiciled

**VOO**
- Tracks the S&P 500
- Domicile: United States
- US estate-tax exposure: Generally yes

#### Ireland-domiciled

**CSPX**
- Tracks the S&P 500
- Domicile: Ireland
- US estate-tax exposure: Generally no

For investors who are neither US citizens nor US-domiciled. Fees, withholding tax, liquidity and tracking still differ.

Shares of an Ireland-domiciled ETF are generally treated as non-US-situated assets for US estate-tax purposes when owned by a non-US citizen who is not US-domiciled.

The important detail is **the fund’s domicile, not the exchange where it trades**.

An ETF listed in London is not automatically Ireland-domiciled. Investors should check the fund’s legal structure and domicile before investing.

Other considerations, including fees, dividend withholding tax, liquidity and tracking performance, still matter.

### 2\. Consider a Joint Brokerage Account

Some brokerages offer joint accounts, including arrangements with rights of survivorship.

Under these structures, the surviving account holder may automatically succeed to ownership when the other holder dies, subject to applicable laws and brokerage procedures.

This can make succession more straightforward.

But there is a crucial distinction: **a joint account does not automatically eliminate US estate tax**.

The deceased person’s taxable interest may still be included in their estate, depending on the ownership arrangement and who contributed the assets.

Investors should also confirm whether their brokerage offers joint accounts and what happens when one holder dies.

### 3\. Understand Lifetime Gifting

Another possibility is transferring investments to family members while still alive.

Under US federal rules, gifts of shares in US corporations by nonresident noncitizens are generally not subject to US gift tax because those shares are intangible property.

That can make lifetime gifting different from leaving the same investments to someone through an estate.

However, a genuine gift means giving up ownership and control. Other tax rules may apply to the recipient, and certain transfers involving retained interests can still create estate-tax complications.

It is an option that deserves professional advice, particularly for larger portfolios.

### 4\. Prepare Your Family for the Practicalities

Some of the simplest measures have nothing to do with changing investments.

A clear will, an up-to-date inventory of brokerage accounts and an executor who knows where the assets are held can make estate administration easier.

Investors can also consider maintaining accessible savings or suitable insurance so their family has liquidity while the estate is being settled.

These measures do not remove the underlying tax liability, but they can reduce uncertainty and financial pressure at a difficult time.

For larger estates, professional advice on trusts or other ownership structures may also be worthwhile. Such arrangements are not automatic tax solutions and can introduce significant costs and complexity.

## THE EDIT

For many Singapore investors, US stocks have become a natural part of long-term wealth building.

But investing across borders introduces considerations that may not be obvious when opening a brokerage account.

A will helps determine who inherits your assets. It does not necessarily determine how those assets are taxed, or how easily they can be transferred.

There is no single estate-planning approach that suits every investor. The right choices depend on portfolio size, family circumstances, investment preferences and tax residency.

Building wealth is one part of investing. Making sure the people you leave it to can actually inherit that wealth is another.
