For many GCC investors, the first question when buying an exchange-traded fund is what does it track? U.S. technology, the S&P 500, global bonds, gold, AI, Saudi equities.
But an equally important question often receives less attention: where is the ETF domiciled?
That distinction can quietly affect long-term returns. Two ETFs can track the same index, own broadly the same securities, and trade in the same currency, yet produce different after-tax outcomes depending on whether they are U.S.-domiciled or structured as UCITS ETFs, usually in Ireland or Luxembourg.
This matters more as GCC investors gain access to a wider range of ETFs through international brokers and local exchanges such as ADX, DFM and Tadawul. A local listing may make trading easier, but it does not automatically change the fund’s legal domicile or tax profile.
Dividend withholding tax
The most visible difference is withholding tax on dividends.
For non-U.S. investors, the default U.S. withholding regime generally applies a 30% tax on U.S.-source income, including dividends, unless a treaty reduces the rate. The IRS describes NRA withholding as a regime that generally requires 30% withholding on U.S.-source payments to foreign persons.That means a GCC investor holding a U.S.-domiciled ETF that owns U.S. stocks will typically see U.S. dividends reduced at source before reaching the investor. For most residents, there is no broad income-tax treaty that reduces this rate in the same way available to some treaty jurisdictions.
Ireland-domiciled UCITS ETFs are different. Because Ireland has a tax treaty with the U.S., Irish ETFs holding U.S. equities commonly face 15% U.S. withholding tax at the fund level rather than 30%. J.P. Morgan notes that Irish ETFs with U.S. equity exposure may benefit from a reduced 15% withholding tax on U.S. dividend income.
For these reasons, GCC investors prefer to own UCITS funds especially for high yielding ETFs and US domiciled for growth oriented or accumulating funds. US funds liquidity tend to be more robust than UCITS liquidity.
Estate tax - For US domiciled ETFs Only
For high-net-worth GCC investors, estate tax is often the more important consideration.
The IRS states that the executor of a nonresident, non-U.S. citizen must file Form 706-NA if the fair market value of U.S.-situated assets at death exceeds $60,000. U.S.-listed stocks and U.S.-domiciled ETFs are generally treated as U.S.-situs assets, meaning they may fall within the U.S. estate-tax net for non-U.S. investors. The Tax can be up to 40%.
This is where UCITS ETFs can have a structural advantage. An Ireland-domiciled UCITS ETF is a non-U.S. fund. Even if it owns U.S. equities, the investor owns shares in the Irish fund, not the underlying U.S. securities directly. For many international investors, that helps reduce or avoid direct U.S. estate-tax exposure. Several international wealth platforms highlight this as a key reason non-U.S. investors often prefer Ireland-domiciled ETFs over U.S.-listed equivalents.
Capital Gains Tax
Capital gains tax applies to profits generated from an increase in the price of an asset rather than from dividend distributions. For example, if an investor purchases an ETF at $10 and later sells it at $12, the $2 profit represents a capital gain.
Fortunately, non-resident investors in both US- and UCITS-domiciled ETFs are generally not subject to capital gains tax, making these structures attractive for many international investors.
Currency Impact
When investing in securities domiciled in foreign markets, local investors typically need to convert AED into USD, EUR, or GBP to purchase the investment, and then convert back into AED upon sale. These currency conversions can create additional transaction costs.
In addition, investors may be exposed to currency fluctuations, particularly in the case of EUR- and GBP-denominated assets. For US-dollar-denominated investments, however, currency risk is relatively limited for UAE-based investors given the AED’s peg to the US dollar.
Cross-listed ETFs Subject to Same Conditions?
A cross-listed ETF is an ETF that is already listed on a foreign exchange, such as the NYSE, but also trades on a local exchange under the same ISIN and structure, in local currency. For example, the Abu Dhabi Securities Exchange currently hosts four NYSE cross-listed ETFs: KraneShares CSI China Internet ETF (KWEB), KraneShares Global Carbon Strategy ETF (KRBN), KraneShares Artificial Intelligence & Technology ETF (AGIX), and KraneShares Wahed FTSE USA Shariah ETF (KWIN).
Cross-listed ETFs remain subject to withholding tax on distributions, similar to their home-market listings, but non-resident investors are generally not subject to capital gains tax. In addition, they are typically not exposed to US estate tax considerations, as the underlying shares are custodied through the local exchange rather than directly under the investor’s name in the US. They can also reduce currency conversion costs, as exchanges such as ADX have negotiated favorable FX rates with First Abu Dhabi Bank for local investors.
U.S. ETFs still have advantages
Tax is not the only factor. U.S.-domiciled ETFs often offer deeper liquidity, tighter spreads, lower expense ratios and a broader product universe. Many innovative strategies launch first in the U.S., from options-income funds to crypto and highly specialised thematic ETFs.
For active traders, that liquidity can offset some tax inefficiency. For long-term buy-and-hold investors, especially those holding U.S. equities for years, the UCITS structure may be more efficient.
The right answer depends on the investor’s objective. A trader may prioritise liquidity. A family office may prioritize estate planning. A dividend investor may focus on withholding tax. A Shariah-conscious investor must also consider screening methodology and the use of derivatives.
The takeaway
For GCC investors, ETF selection should not stop at the index. It should include a review of domicile, tax leakage, estate-tax exposure, distribution policy and local accessibility.
As a rule of thumb, U.S.-domiciled ETFs offer depth and innovation, but often come with higher dividend withholding and potential U.S. estate-tax exposure. Ireland-domiciled UCITS ETFs may offer lower withholding on U.S. equity dividends and reduce estate-tax concerns, but can have different liquidity, costs and product availability.
In a region where investors are increasingly using ETFs for global exposure, tax structure is no longer a technical footnote. It is part of the return.
