If you are a UAE resident investing in US stocks or funds, you pay no tax to the UAE - not on income, not on capital gains, not on dividends.
But the United States withholds 30% of the dividends paid to you by American companies, and you cannot reduce that rate, because there is no tax treaty between the two countries.
In return, the United States does not tax your capital gains when you sell the shares. This contrast - full withholding on distributions, exemption on gains - is the heart of what a Gulf investor needs to understand.
First: The UAE Side - No Tax, and That Is Certain
The UAE does not levy a personal income tax on individuals. There is no personal tax return, no capital gains tax, and no tax on the dividends an individual receives.
What about the 9% corporate tax? It applies to financial years beginning on or after 1 June 2023, and it is a tax on business - not on the personal investments of individuals.
Cabinet Decision No. 49 of 2023 states this explicitly: activities that generate personal investment income are not treated as a business or commercial activity, regardless of the amount of revenue. Personal investment is defined as investment activity carried out by a natural person for their own account, without a licence, and without being treated as a commercial activity.
A common correction: the AED 1 million threshold mentioned in the decision is not an investment exemption. It is a test for the revenue of a business activity, and personal investment income does not enter that calculation at all - no matter how large your portfolio is.
Cases that call for professional advice: if you trade through a licensed entity, hold a commercial licence, or your activity is classified as a business.
Second: Why Does the US Withhold 30% - and Why Can It Not Be Reduced?
The United States imposes on a non-resident alien a withholding tax of 30% on income from US sources, including dividends on shares. This is the statutory rate.
Investors in other countries usually reduce it to 15% or 10% through a double-taxation treaty between their country and the United States.
And here is the key difference: there is no tax treaty between the UAE and the United States. The UAE does not appear on the IRS list of income tax treaties in force - nor does any other Gulf state. As a result, the rate remains a full 30%, with no possibility of reduction or refund.
A Trap Many People Fall Into
If you search, you will find an official document on the IRS website that carries the UAE's name. This is not a tax treaty - it is an arrangement relating to the FATCA law, that is, the exchange of bank account information between financial institutions.
The distinction is decisive: FATCA transfers information about accounts, does not reduce any tax rate, and creates no tax obligation on you. The obligation falls on the bank or the broker, not on the individual.
Third: What Does the W-8BEN Form Actually Do?
An important correction: a claim spreads across Arabic and Gulf websites that filling in the W-8BEN form reduces withholding to 15% for UAE residents. This is not true. That applies to countries that have a tax treaty - and the UAE is not one of them.
So why fill in the form at all? Because it is required in every case, whether you are claiming a reduction or not. Its function is threefold:
Prove that you are not a US person - otherwise the broker treats you as a US resident.
Avoid 'backup withholding' of 24% - and this is the real danger, because it may be applied to the gross sale proceeds, not just to distributions.
Document the account with the broker.
The rate on distributions remains 30% in both cases. The form is valid until the end of the third calendar year following the year of signature, and then must be renewed. Most platforms request it when you open the account - check your platform.
Fourth: The Good News - No Tax on Your Capital Gains
When you sell a US share at a profit, the United States does not tax that profit if you are a non-resident alien and are not present in the United States.
The US rule imposes a 30% tax on capital gains only on someone who has spent 183 days or more inside the United States during the tax year. In other words, physical presence is what triggers the tax, not the reverse.
Exceptions to watch for:
The 183-day rule - if you spend that period in America.
US real estate (FIRPTA) - gains from selling US real property interests are taxable, and this may include US REITs, not just direct real estate.
Fifth: The Point Everyone Misses - US Estate Tax
This is the most important section of the article, and the most overlooked in Arabic-language content.
If a non-resident alien dies while owning assets situated in the United States, those assets are subject to US estate tax (inheritance tax).
Exemption threshold for a non-resident alien: only USD 60,000.
Top tax bracket: 40%.
Estate treaty between the UAE and the US: none.
For comparison: a US person enjoys an exemption exceeding several million dollars. The USD 60,000 threshold for foreigners has not been adjusted for inflation.
And most importantly - which assets count as 'situated in the United States'? The US rule is clear: shares of companies incorporated under US law are treated as US assets, regardless of where the securities are held or where the owner resides. In practice this extends to exchange-traded funds domiciled in the United States.
Shares of non-US companies - including funds domiciled in Ireland - are not treated as US assets.
Illustrative example: a UAE resident who holds USD 500,000 in a US-domiciled fund creates US tax exposure on their estate. Had the same amount been in a fund domiciled in Ireland, this would not apply - because the fund's domicile is different.
This issue is far more consequential than differences in withholding rates, and it calls for professional advice if your US assets exceed USD 60,000.
Sixth: Irish-Domiciled Funds - Why Are They Treated Differently?
Many Gulf investors use index funds domiciled in Ireland instead of their US counterparts. The reason is purely regulatory.
Ireland has a tax treaty with the United States. Under its Article 10, the tax on distributions does not exceed 15%. And Article 4 of the treaty treats an Irish collective investment fund as a tax resident of Ireland - which is what gives it the right to the reduced rate.
Then there is no second withholding layer: Ireland does not withhold tax from distributions to investors who are not resident there.
The result: the Irish fund bears 15% on the US distributions inside it, while the US fund means 30% reaching you directly.
The Practical Comparison
An illustrative calculation prepared by el fondo - not an official figure. Based on an S&P 500 index dividend yield of about 1.05% in August 2026; this yield varies, and the result changes with it.
In summary: the US-domiciled fund carries an approximate total drag of about 0.35%, versus about 0.23% for the Irish-domiciled fund. Critically, only the US-domiciled fund counts as a US asset for estate-tax purposes; the Irish-domiciled one does not.
Do not overstate the annual difference. At the current yield level, the gap is about 0.12% per year - a modest amount. The larger and more certain difference is the estate-tax question in the previous section, not the basis points.
And the higher the dividend yield, the wider the gap: at a 2% yield, the withholding difference alone becomes about 0.30% per year.
Note: some 'synthetic' Irish funds use derivative mechanisms that may reduce withholding further. The mechanism is complex and varies between funds - read the fund's own prospectus, and do not generalise.
Seventh: Special Cases to Watch For
US citizens or green card holders resident in the UAE: everything above is turned upside down for you. Irish funds are classified for you as a PFIC and are subject to harsh US tax treatment. The situation is entirely different - consult a US specialist.
Those who spend a long time in the United States: the 183-day rule and the substantial presence test may change your tax position entirely.
Those who own US real estate or REITs: FIRPTA rules apply.
Those who hold tax residency in another country alongside the UAE: that country's rules may override everything above.
Eighth: Do You Have a Disclosure Obligation in the UAE?
We found no personal disclosure obligation on individuals resident in the UAE regarding foreign securities. There is no personal income tax, no personal tax return, and the referenced decision states explicitly that a natural person outside the scope of corporate tax is not required to register.
As for FATCA and CRS, the UAE is a party to them - but the obligation falls on financial institutions, not on the individual. They transfer information about accounts for the purposes of international tax transparency, and create no UAE tax on you.
Frequently Asked Questions
Do I pay tax in the UAE on the profits from my US shares? No. The UAE does not levy income tax on individuals, nor tax on capital gains or distributions.
How much does the US withhold from my dividends? 30% of distributions from US shares and funds, with no possibility of reduction, because there is no tax treaty between the two countries.
Does the W-8BEN form reduce the rate to 15%? No. This is a common claim, but it is not true for UAE residents. The form proves you are not a US person and protects you from the 24% backup withholding, but it does not reduce the rate on distributions.
Do I pay tax when I sell a share at a profit? The United States does not tax the capital gains of a non-resident alien, unless they have spent 183 days or more inside it, or the asset is US real estate.
What is the difference between a US and an Irish fund? The Irish one bears 15% withholding instead of 30% thanks to the Ireland-US treaty, and is not treated as a US asset for estate-tax purposes - and this is the most important difference.
What is US estate tax and why does it concern me? If you own US assets exceeding USD 60,000, your estate may be subject to a US tax of up to 40%. Funds domiciled outside the United States do not fall within this scope.
