A founder who lives in Dubai sells to American customers through a Wyoming LLC. A Hong Kong company owns a Delaware LLC that runs its US web shop. A consultant who has moved to Lisbon invoices through a single-member LLC. Sooner or later the same sentence comes up in each of these situations: the LLC is transparent, so for tax purposes it does not exist. In the United States that is often correct. The question that tends to be skipped is whether any other country agrees.

Whether an LLC is ignored for tax purposes is decided by the US tax rules, and those rules bind only the United States. Every other country decides for itself what a US LLC is, and most of them look at its legal form rather than at a box ticked on a US tax form. The result can be an LLC that is invisible in the US and a fully fledged company everywhere else, with consequences for where it is resident, for the tax on what it pays out and for exemptions that everyone assumed would apply. In this article we set out the US starting point and then look at how the United Arab Emirates and Hong Kong see the same LLC, with a shorter look at owners in Europe and at what happens on a sale. Not a complete legal handbook, but a practical overview of the questions that decide the outcome.

1. Transparent in the US does not mean transparent everywhere

Under the US rules an LLC with a single owner is disregarded by default: it is not a taxpayer, and its income and expenses are treated as those of its owner. An LLC with two or more members is treated as a partnership, which is transparent as well. Either can opt to be taxed as a corporation instead. For a foreign owner whose LLC has no business in the US, the default outcome is frequently that no US income tax is due at all.

That is what makes the LLC so popular with internationally mobile entrepreneurs, and it is also where the risk sits. A profit that the US does not tax will be taxed, or not, according to how the owner’s own country sees the LLC. Transparency is not a characteristic of the LLC itself. It is the way one tax system, the American one, chooses to look at it.

If another country sees a company where the US sees nothing, three questions open up. Where is that company resident? Does a distribution from it qualify for an exemption when it reaches a parent company? And do rules aimed at low-taxed foreign entities apply to its owner? The answers differ from country to country, which is why the rest of this article works through them one jurisdiction at a time.

2. What the US itself sees

Disregarded does not mean invisible to the IRS. A single-member LLC owned by a foreign person must file an information return every year, Form 5472 attached to a pro forma corporate return, reporting the transactions between the LLC and its owner. For that purpose the US rules even treat the LLC as a domestic corporation. The penalty for a missing or incomplete form is USD 25,000 per form per year, which makes it one of the more expensive oversights in international tax.

Whether any US income tax is due depends on whether the LLC carries on a trade or business in the US. If it does, the profit connected with that business is taxed in the hands of the owner. A foreign company pays 21% federal tax on it and, without a treaty, a 30% branch profits tax on profit taken out of the US, while an individual owner pays the individual rates. Neither the UAE nor Hong Kong has an income tax treaty with the US, so those rates apply in full. Keeping stock in a US warehouse, for example through a fulfilment service, can be enough to create a US business, and where exactly the line lies is a question of fact on which advisers regularly differ.

The owner can also elect to have the LLC taxed as a US corporation. It then pays 21% on its own profit, and dividends to a foreign shareholder bear 30% US withholding tax unless a treaty reduces it. The election can take effect at most 75 days before it is filed, and after a change of classification a further change is generally not possible for five years. One more point for individuals who hold an LLC personally: for non-residents, US estate tax on US assets has an exemption of only USD 60,000, and whether a disregarded LLC shields its US assets from that tax is not settled.

3. How other countries decide what an LLC is

Most countries classify a foreign entity by comparing it with their own legal forms. They ask whether it has legal personality, whether its members are liable for its debts, whether profits belong to the members as they arise or only once they are distributed, and whether interests in it can be transferred. The US election plays no role in that comparison, because it is a choice for US tax purposes and says nothing about what the entity is under company law.

Measured against those criteria, a US LLC usually looks like a company. It is a legal person under the law of the state where it was formed, its members are not liable for its debts, and profit reaches them through a distribution rather than automatically. Most countries therefore treat it as opaque: the profit belongs to the LLC until it is paid out. For an LLC with several members some countries look more closely at the operating agreement, but for a single-member LLC the conclusion is almost always the same.

An opaque LLC is not necessarily a problem. It can simply mean that tax in the owner’s country only arises on distribution. But it does turn the three questions from the previous section into real ones, and the countries we deal with most often answer them in quite different ways.

4. The UAE: a company, and possibly a UAE resident

The UAE corporate tax rules have no equivalent of the US election. A foreign entity is classified on its own legal features, and a US LLC is a juridical person, so for the UAE it is a company. Tax transparency in the UAE is reserved for partnerships and comparable arrangements between two or more persons, and for foreign partnerships only under specific conditions. A single-member LLC is neither, so its profit is not attributed to its owner as it arises.

That sounds attractive for an owner who lives in the UAE, since individuals pay no income tax there on dividends. The catch is residence. A company formed abroad is resident in the UAE if it is effectively managed and controlled in the UAE. An LLC whose only member lives in Dubai, and whose decisions are all taken there, may on those facts well be a UAE resident company. It must then register for corporate tax, file returns and pay 9% on its worldwide profit above AED 375,000. Small Business Relief can reduce that to nil for businesses with revenue of up to AED 3 million, and in August 2026 that relief was extended to tax periods ending no later than 31 December 2029.

Where a company is managed is a question of fact: where the strategic decisions are taken, by whom, and how that is recorded. For many founders the honest answer is that the LLC is run from a laptop in Dubai. That does not make the structure wrong, but it does mean the UAE position should be a conscious choice rather than a surprise. And any US tax on a US business comes on top, because there is no treaty to relieve double taxation.

5. A UAE company holding the LLC: the participation exemption

Many structures put a UAE company between the owner and the LLC. Distributions from the LLC then rely on the UAE participation exemption, which requires an interest of at least 5%, held for at least twelve months, in an entity that is subject to corporate tax, or a similar tax, at a rate of at least 9% in its country of residence. The guidance of the Federal Tax Authority (FTA) makes this a test of the tax system: if the statutory rate in that country is 9% or higher, the condition is met without recalculating anything. Only where the statutory rate is below 9% does the effective rate come into play.

For a disregarded LLC the rate is not the problem, since the US federal rate is 21%. The problem is residence. In favour of treating the LLC as a US resident: it is a legal person under US law, formed in the US, with its own tax identification number and its own filing obligation. Against: it is not a taxpayer in its own right, and the US will not issue a certificate of residence in its name. The FTA has not published a position on this specific case, so a taxpayer who relies on the exemption is taking a position that may be challenged.

In practice there are three routes. If the LLC is managed from the UAE, it is a UAE resident, and dividends from a UAE resident company are exempt without further conditions, but the LLC then pays 9% itself. If the LLC elects to be a US corporation, the exemption is clearly available, at the price of 21% US tax and 30% withholding on dividends. And if the LLC stays disregarded and is managed outside the UAE, the exemption is arguable but uncertain, and if it is refused the dividend is taxed at 9% without any credit. Note that the first and third routes both end at roughly 9%: the difference is timing and certainty, not the rate. The election is therefore rarely worth it for UAE reasons alone. It becomes logical when the LLC has a US business anyway, because the US then taxes the profit in either form and the election removes the discussion in the UAE.

6. Hong Kong: outside the net, until the money comes in

Hong Kong taxes only profits that arise in Hong Kong from a business carried on there. It has no election either, and it treats a US LLC as a separate company. Profits the LLC earns through operations outside Hong Kong are therefore not taxed in Hong Kong, even if the Hong Kong parent sets the strategy, because under the Hong Kong source rules it is where the operations take place that counts, not where the decisions are made.

The question moves to the Hong Kong company that receives the distributions. Since 2023, foreign-sourced dividends, interest and gains on shareholdings that are received in Hong Kong by a company belonging to a multinational group are treated as Hong Kong profits and taxed, unless an exception applies. A multinational group in this sense requires no minimum size: a Hong Kong company with a single US subsidiary already is one.

There is a preliminary question here that many overlook. The Hong Kong tax authority describes a dividend as a payment in respect of a share in a company, and an LLC has membership interests rather than shares. It is therefore not certain that a distribution from an LLC is a dividend within the meaning of these rules at all. That goes some way to explaining why many structures appear to run without friction, but it is not a foundation on which we would build.

7. Hong Kong: why the participation exemption rarely helps, and what does

The Hong Kong participation exemption requires an interest of at least 5% held for twelve months, and a subject-to-tax condition: the income, or the profits from which it is paid, must actually have been taxed at a headline rate of at least 15%. The tax authority’s own examples make clear that income exempt in a country with a 20% rate does not meet the condition, because no tax was charged on it. A disregarded LLC without a US business pays no tax anywhere, so the condition fails, even though the US rate on paper is 21%.

This is where Hong Kong and the UAE part ways. The same LLC can pass the UAE test, which looks at the tax system, and fail the Hong Kong test, which looks at the tax actually charged. The Hong Kong condition is met if the LLC elects corporate status, or if it has a US business whose profit is taxed in the US.

Two other routes remain. The first is economic substance. A company that does nothing but hold shareholdings faces a reduced test: it must meet its registration and filing obligations and have adequate people and premises in Hong Kong to hold and manage its interests. It may outsource that to a Hong Kong service provider, provided the work is actually done in Hong Kong under the supervision of the board. A nominee director while the management takes place elsewhere is not enough, and as soon as the company also lends money, charges fees or recharges costs, the full substance test applies. The second route is not to receive the money in Hong Kong: a distribution paid to an account outside Hong Kong and passed on from there is not received in Hong Kong, but using it to pay Hong Kong expenses counts as receipt. If none of these routes works, the distribution is taxed at the ordinary profits tax rate of 16.5%, without a credit.

8. An owner in Europe: opaque, but not out of reach

Most European countries also classify a US LLC by its legal form, and most conclude that it is a company. For an owner who lives there, that sounds like deferral: no tax until the LLC distributes. In practice the owner’s country usually has a second line of defence. Every EU country is required to apply controlled foreign company rules to companies resident there, and several apply similar rules to individuals. Those rules can attribute income of a low-taxed foreign entity to the person who controls it, every year and regardless of any distribution. Which income is caught differs per country: some rules target passive income such as interest and royalties, others any arrangement without real substance, and some cast the net wider. A disregarded LLC that pays no tax anywhere is exactly the kind of entity those rules look at.

Some countries go further and treat certain low-taxed foreign entities as transparent for their residents by statute, whatever the entity looks like under company law. Others have not taken a clear position on single-member LLCs at all. Portugal is an example: its tax authority has ruled that an LLC with two members is not transparent, but it has never published a ruling on a single-member LLC owned by a Portuguese resident, and advisers read the rulings that do exist in different ways.

For an owner in Europe the question is therefore less whether the LLC is transparent and more whether its profit is attributed to the owner anyway. Putting a Hong Kong or UAE company in between does not automatically solve that, because many of these rules also look at entities held indirectly.

9. Selling the LLC: where the uncertainty becomes expensive

The questions in this article matter every year, but they matter most on a sale. For the US, selling a disregarded LLC is selling its assets: the buyer takes over the business itself, and the part of the gain that relates to a US business can be taxed in the US. Buyers often welcome that, because they get a fresh starting value for the assets. Selling the shares of a US corporation is different: for a foreign seller that gain is generally not taxed in the US, unless the company mainly holds US real estate.

In the UAE a gain on selling a participation falls under the same participation exemption as a dividend, including the subject-to-tax question discussed above. Two details make a sale more demanding than a dividend. The twelve months must actually have passed at the moment of the sale, because an intention to hold the interest for longer does not count here. And if the exemption is refused, the whole gain is taxed at 9% in one go. A position that costs little on an annual dividend can therefore become a significant exposure on an exit, which is reason enough to settle the classification well before a sale is on the table.

In Hong Kong, gains on the sale of shareholdings have been covered by the same regime as dividends since 2023, and broadly the same exceptions apply. Here too the subject-to-tax condition is hard to meet for a disregarded LLC, so the substance route or keeping the proceeds outside Hong Kong usually has to do the work. And whoever is considering the US election should put it in place well before a sale: it can take effect at most 75 days before it is filed, and changing classification shortly before a sale raises questions of its own.

10. What to settle before the first profit

The LLCs that cause trouble tend to share a pattern: the structure was chosen because the LLC is transparent in the US, and nobody asked how it looks from the country where the owner lives or where the parent company sits. The ones that work have usually answered a short list of questions at the start.

For every country involved: is the LLC a company there, where is it resident, and does what it pays out qualify for an exemption? On the US side: are the annual Form 5472 filings in order, and does the LLC have a US business, now or once stock is held in the US? On the election: is it a deliberate choice made before the first profit, with the US cost of 21% and the withholding on dividends set against the certainty it buys, and with the five-year lock in mind? On management: are decisions taken, and recorded, in the country where the LLC is meant to be resident, and is that consistent with the position taken elsewhere? For a Hong Kong parent: which exception is relied on, and do the money flows actually match it? And if a sale is conceivable within a few years: is all of this settled now, rather than during the buyer’s due diligence?

A US LLC is a flexible and inexpensive vehicle, and in the right structure it does exactly what it promises. The mistake is to assume that the US answer is the only answer. If you hold an LLC from the UAE, Hong Kong or elsewhere, or you are about to set one up, we are happy to think it through with you, preferably before the classification is decided for you.
