US Estate Duties: The large & unrecognised risks faced by global investors
Understanding the true cost of US Estate Duties - beyond the 40% headline number | Published: 30-Jun-26

The true risks of US Estate Duties for Global investors is often vastly underappreciated.
While many investors may be aware of the 40% estate duty tax on US-situs assets, most are not aware of the extremely complex operational complexities involved in US Estate Settlement, the short timelines, aggressive penalties and the substantial MTM risk that can lead to actual effective estate duties reaching upto 100% of assets.
Even more dangerous, are attempts to try to evade this (the sale-and-transfer myth), that exposes beneficaries to substantial criminal (upto 8 years imprisonment) and monetary liabilities (large & substantial penalties) with a clear legal pathway for the US IRS to enforce the same.
This whitepaper does a deep dive into US Estate duty risks for Global investors, touching upon details most investors remain unaware of, and explains how proper structuring can help avoid US Estate Duties all-together.

Summary of the Core Message
Understanding US Estate Duties
Many global investors seek to include exposure to US assets (especially US equities) as part of their portfolios, but do so without the due-care required when dealing with cross-border investments. Too many investors inadvertently end up owning US-situs assets (US stocks, US ESOPs, Real Estate etc), exposing their wealth to a substantial 40% estate duty tax, dramatically reducing the amount of wealth passed down to their beneficaries.
The first section of the whitepaper, focusses on helping investors gain a deeper understanding of US Estate Duties - what they are, what assets they apply on and whether there are there any exceptionson the same.
Wealth Destruction + The operational nightmare of compliance
While many investors are aware of the 40% US Estate Duty Tax, most are not aware of the sheer operational complexity involved in the estate settlement process in the US. From frozen custodian accounts, the potential need to hire a US attorney, strict timelines for tax assessment & payments (with sharp penalties for delays), and the long wait for the IRS to issue a transfer certificate - beneficaries are looking at a min of 1-3 years before they can expect to get back their inheritance, with complex & expensive operational processes to be followed.
Arguably, the biggest problem however arises from the huge MTM (mark-to-market) risk, that timing mismatches between Estate tax finalisation, tax payment and the final settlement of accounts by custodians, exposes beneficaries to. In a declining market, MTM risk can lead to the actual effective duty rising from 40% to upto 100% of total assets - a risk most investors continue to be unaware of.
Non-compliance is really not an option
Many investors have been given extremely wrong & dangerous advice, that in the case of death, beneficaries should just sell and transfer back the money to their home countries (with a mistaken belief that this can help avoid estate duties). The legal implications of any such move is massive - providing a clear auditable trail that the US IRS can use to prove active intent for tax-evasion & tax fraud (exposing beneficaries to upto 8 years in imprisonment), along with rapidly balooning fines & penalties (2-3x of the original tax owed).
Importantly, rapidly rising cross-border information sharing agreements, the existence of a automatic lein mechanism that converts an estate liability into a beneficary liability, and a host of cross-border enforcement mechanisms, makes this a very real risk that no sensible investor would wish their beneficaries to bear.
Proper stucturing provides easy solutions and helps avoid this risk all-together
Importantly, a little careful due-diligence at the time of investing, can help investors gain access to US markets - without them getting any exposure to US-situs assets. All the complexity & wealth destruction linked to compliance, or the humongous criminal & monetary liabilities linked to non-compliance, are extemely easy to avoid by just using the right route to build US market exposure.
