A British entrepreneur does everything right. He leaves the UK, settles in Malta, and runs his business through a Maltese trading company. The headline rate is 35 percent, but after the famous 6/7ths refund his effective corporate tax sits at roughly 5 percent. For years the structure is close to perfect. Then life moves on. He meets someone, spots an opportunity, or simply wants a new chapter, and he decides to move to the United States. Naturally, he would like to keep the Maltese company running exactly as it is.
That is the moment the structure quietly turns against him.
The Maltese company is not the problem. The problem is what American tax law does to a foreign company the day its owner becomes a US tax resident. Every feature that made Malta brilliant for a European resident becomes a precise trigger that makes the same company expensive, complicated, and in some cases punitive for an American one. This is one of the most common and most underestimated mistakes we see, and it is entirely avoidable if it is handled before the move rather than after.
The structure that worked perfectly
Malta’s appeal is mechanical and well established. A Maltese company pays the 35 percent headline rate, then distributes a dividend, and the non-resident shareholder claims a refund of six sevenths of the tax paid on trading income. The cash that stays with the Maltese treasury is about 5 percent of the original profit. For passive interest and royalties the refund is five sevenths, leaving roughly 10 percent. The refund is real, it is written into Maltese law, and in 2026 it is still fully operational.
Two details matter enormously once an American move enters the picture. First, the refund is paid to the shareholder, not to the company. The company’s own accounts only ever show the 35 percent charge. Second, the whole system was designed around a non-resident, non-domiciled shareholder. It assumes the person collecting the dividend and the refund is taxed lightly, or not at all, in their country of residence. The United States makes exactly the opposite assumption.
Why America changes everything
The United States taxes its citizens and its tax residents on worldwide income, wherever it is earned and wherever the company sits. There is no territorial escape hatch for an individual.
The trap does not spring on the day your visa is approved. It springs on the day you become a US tax resident, which is a separate question from immigration status. You become a tax resident either by holding a green card or by meeting the substantial presence test, a day-counting formula that catches most people who actually live in the country across a year and the two preceding years. This distinction matters for British clients in particular, because the United Kingdom is an E-2 treaty country and many arrive on an investor visa believing they have flexibility. In practice, if you live in the United States, you will almost certainly be a tax resident, and from that point your Maltese company is no longer a foreign company that America ignores. It is a foreign company that America watches very closely.
Trap one: the CFC and the annual phantom tax
Once you are a US person owning a controlling stake, your Maltese company becomes what the IRS calls a controlled foreign corporation, reported every year on Form 5471. A foreign company is a controlled foreign corporation when US shareholders who each own at least 10 percent together own more than 50 percent by vote or value. A single owner-manager clears that bar instantly.
The consequence is brutal in its simplicity. As a US shareholder of a controlled foreign corporation, you are taxed each year on your share of the company’s profits whether or not the company distributes anything to you. The regime that does this was known as GILTI and, for tax years beginning in 2026, has been renamed Net CFC Tested Income, calculated on Form 8992. The deferral that makes a normal company useful, the ability to leave profit inside the business and reinvest it, simply disappears. You pay US tax on money you may never take out. Tax professionals call it phantom income, and it is exactly as unpleasant as it sounds.
Trap two: the low Maltese rate is the problem, not the prize
Here is the part that catches people who think a low tax rate is always good news.
The Net CFC Tested Income rules contain a high-tax exception. If your foreign company already pays local tax at roughly 14 percent or more under the 2026 rules, that income can be carved out of the US inclusion entirely. Many American business owners living in higher-tax countries sail under this exception without realising it.
Malta does the opposite. Your effective Maltese rate of around 5 percent sits far below that 14 percent line, so none of your income qualifies for the exception. Worse, the foreign tax credit you can use to offset the US charge is limited to the tax actually suffered in Malta, which after the refund is tiny. The United States now allows a credit for 90 percent of the foreign tax paid, but 90 percent of almost nothing is still almost nothing. The 35 percent you nominally paid does not help you, because 30 of those points came back as a refund. In other words, the very mechanism that gave you a 5 percent rate in Europe leaves you with almost no shield against US tax in America. The structure was optimised for the wrong country.
And if you hold the shares as an individual rather than through a US corporation, the included income is taxed at your ordinary rates, up to 37 percent, not at a gentle corporate rate. The mismatch could hardly be sharper.
Trap three: the passive company overlap
If your Maltese company is less of an operating business and more of an investment or holding vehicle, a second regime waits behind the first. A company that is mostly passive, by income or by assets, can be a passive foreign investment company, subject to the punitive rules filed on Form 8621. These rules can tax gains at the highest ordinary rates and add an interest charge on top, stripping away the favourable treatment that capital gains normally enjoy.
For a controlling owner the controlled foreign corporation rules usually take priority and displace the passive company rules. But the passive company trap becomes very live the moment you start restructuring, for example if you sell down your stake and slip below the control thresholds while the company still throws off passive income. A fix for one trap can open another. This is why the sequencing of any restructuring matters as much as the restructuring itself.
Trap four: the paperwork that never ends
Even before you calculate a cent of tax, ownership of a foreign company as a US person brings a compliance load that surprises almost everyone. Form 5471 for the controlled foreign corporation. Form 8992 for the annual income inclusion. Form 8621 if the passive company rules apply. Form 926 for transfers of property into the company. An FBAR for foreign accounts, and Form 8938 for foreign financial assets. The penalties for getting these wrong are measured in tens of thousands of dollars per form, and they apply whether or not any tax was actually due. The United States and Malta do have an income tax treaty, but its saving clause lets America tax its own residents largely as if the treaty were not there, so it offers far less shelter than people hope.
The window that closes on day one
Almost every good solution to this problem has to happen before you become a US tax resident. After that date, your options narrow sharply and most of them carry a US tax cost. The pre-immigration window, often the months between deciding to move and actually triggering residency, is the single most valuable planning period you will ever have, and most people spend it booking flights and schools rather than restructuring. The goal in that window is simple to state and technical to execute: enter the United States with a structure that America can live with, and with your historic profits already dealt with on Maltese terms rather than American ones.
The alternatives worth examining
There is no single correct answer here. The right path depends on whether the company is an active business or a holding vehicle, how much retained profit has built up, whether there are genuine non-US co-owners, and what you actually want the company to do in five years. These are the structures we work through, roughly in the order they should be considered.
Clean out and reset before you land
Often the most powerful and least exotic move. While you are still a non-US person, distribute the accumulated profits and let Malta tax them at its favourable rates, so that those earnings never become future US phantom income. Where appropriate, realise gains and reset your basis to current market value before residency starts, because the United States generally does not tax pre-residency gains that are crystallised before you arrive. In some cases the cleanest outcome is to wind the company down entirely, take the proceeds out at Maltese rates, and start fresh in the United States with a structure built for American rules from day one.
Bring it onshore as a US corporation
If you genuinely want to keep operating the business and you intend to retain profits inside it, a US C corporation is often more efficient for an American than holding a foreign company directly. A US corporation, unlike an individual, gets the better end of the international rules and a more generous foreign tax credit, and it removes the controlled foreign corporation machinery from your personal return. The cost is the classic one: a layer of corporate tax, then tax again when profits are distributed to you. You also give up Malta’s 5 percent. For an active business that throws off cash you want to live on, this is frequently the honest answer.
Re-domicile or relocate the operating company
Tempting, and frequently misunderstood. Moving the company to a different country does not, by itself, escape the controlled foreign corporation rules, because those rules apply to any foreign company a US person controls, regardless of which flag it flies. Relocation only helps when it is paired with real substance and an active business that genuinely qualifies for an exception, or when the destination’s own tax rate is high enough to clear the high-tax line. Changing the address without changing the economics solves nothing.
The check-the-box election
A Maltese private limited company is generally an eligible entity for US purposes, which means it can elect to be treated as a flow-through rather than a corporation. Done correctly, this can switch off the controlled foreign corporation and passive company machinery entirely, so the income simply flows up to you once and is taxed once, with a credit for the Maltese tax. The catch is timing. Making this election after you are already a US person triggers a deemed liquidation of the company, which is a taxable event on your watch. Making it during the pre-immigration window can achieve the same end with no US tax cost. The election is a scalpel, and the date you sign it changes everything.
Sell a genuine stake to a non-US person
If a real, unrelated, non-US partner or family member buys a meaningful share of the company at fair value, you can fall below the controlled foreign corporation thresholds, and the annual phantom income problem can fall away with it. The warnings here are serious. The sale has to be economically real, not a paper arrangement that leaves you in control. US attribution rules treat shares owned by your spouse, your children, your parents and your grandparents as if they were yours, so selling to a US spouse or to your own children achieves nothing. And dropping below control can expose you to the passive company rules described earlier if the company is investment-heavy. This works, but only when the new owner is genuinely independent and the structure is built with the attribution rules in full view.
The Section 962 election
Not a structure but a mitigation. A US individual can elect to be taxed on the controlled foreign corporation income at corporate rates and to claim the corporate-style foreign tax credit. It softens the blow, especially where some meaningful foreign tax exists, but it does not remove the problem, and a second layer of tax can apply when the cash is finally distributed to you. Useful as a patch, rarely the whole answer.
A pre-immigration trust
For clients with real wealth and a family dimension, an irrevocable trust established before US residency, while you are still a non-US person, can be one of the strongest tools available. Properly built as a foreign non-grantor trust, it can move the company out of your personal ownership, take it off your future US estate, and break the direct line of attribution. The discipline required is considerable. US rules can treat you as the owner of a foreign trust if they are not respected to the letter, distributions to US beneficiaries can be hit by accumulation and throwback charges, and the reporting on Forms 3520 and 3520-A is unforgiving. A pre-immigration trust is a precision instrument, not a template, and it has to be in place before you arrive.
Mind the visa, not just the company
Finally, remember that the trap is triggered by tax residency, and tax residency is partly within your control. A British client arriving on an E-2 investor visa is in a different position from one arriving on a green card, and how many days you spend in the country can decide whether the substantial presence test catches you in a given year. For some clients, structuring the move so that residency begins on a chosen date, after the company has been cleaned up, is the difference between a smooth transition and an expensive one.
There is no off-the-shelf answer
The recurring lesson is that the Maltese company is rarely the villain. The villain is timing and sequence. The same company can be a 5 percent asset or a phantom-income liability depending entirely on what is done in the months before the owner becomes American. A move that looks like a single decision, change of country, is in fact a stack of decisions about entity classification, distributions, basis, ownership and residency date, each of which has to be made in the right order and almost all of which have to be made early.
If you are sitting in Malta with a company you are proud of, and America is on your horizon, the worst thing you can do is assume the structure simply travels with you. It does not. Plan the company move before you plan the personal one.
