Form 5471 for a UAE free zone company is required every year a US citizen or Green Card holder owns or controls it, whatever the UAE rate. From 2026 most trading profit falls under the NCTI regime, and because the company pays no UAE tax there is no foreign tax credit to offset the US charge. It lands in full.
That is the part of the Dubai structure nobody puts in the brochure. The 0% rate is real in the Emirates and irrelevant in Washington, because the United States taxes its citizens on worldwide income and looks straight through a foreign company its citizens control. This guide covers what the IRS wants, what the UAE wants by 30 September 2026, and where the two collide.
Why a zero-tax company still creates a US tax bill
A foreign corporation is a controlled foreign corporation (CFC) when US shareholders, each owning 10% or more, together own more than 50% of it by vote or value. An American who owns a Dubai free zone company outright is inside that definition on day one.
Two regimes then pull the company's profit onto the owner's US return, whether or not a dirham is paid out:
- Subpart F catches passive income such as interest and dividends, and foreign base company sales and services income, which typically arises when the company trades with related parties.
- Net CFC tested income (NCTI) catches most remaining active trading profit for tax years beginning after 31 December 2025. NCTI replaced GILTI under the One Big Beautiful Bill Act: the section 250 deduction fell from 50% to 40%, the QBAI exclusion was repealed, and the deemed-paid credit haircut narrowed from 20% to 10%.
None of this depends on distributions. The inclusion happens annually, on the owner's Form 1040, from the numbers reported on Form 5471.
The NCTI arithmetic when foreign tax is zero
For a UK company, NCTI is often painless: the deemed-paid credit carries 90% of UK corporation tax across, which usually covers the US charge. A qualifying free zone company pays 0%, so that mechanism has nothing to carry. What remains is a choice between two ways of being taxed.
| No election (individual) | Section 962 election | Same profit in a UK company, with election | |
|---|---|---|---|
| Rate on the inclusion | Ordinary rates, up to 37% | 21%, reduced by the 40% section 250 deduction — about 12.6% | About 12.6% before credit |
| Foreign tax credit | None available | None — UAE tax paid is nil | 90% of UK corporation tax deemed paid |
| Typical net US charge now | Full ordinary rate | About 12.6% | Often nil |
| When profit is later distributed | Previously taxed; generally not taxed again | Taxable to the extent it exceeds the tax already paid | Taxable, but a UK dividend can be qualified |
The irony is structural: the 0% rate that made the structure attractive is exactly why the US charge cannot be credited.
The second layer: distributions from a UAE company
A section 962 election is not free. When the company later distributes profits that were taxed under the election, the amount exceeding the US tax already paid is taxable again as a dividend.
That second layer is where the UAE differs sharply from Britain. There is no comprehensive income tax treaty between the United States and the UAE, so a UAE company's dividends are not qualified dividends unless its shares are readily tradable on a US exchange. They are taxed at ordinary rates of up to 37%, potentially with the 3.8% net investment income tax on top.
So the honest comparison is two layers against one. Paying about 12.6% now and ordinary rates on distribution can beat paying full ordinary rates now — or lose to it — depending on how long profits stay in the company. That is a modelling question, not a default.
Which Form 5471 categories apply
- Category 4 — a US person who controlled the company during the year.
- Category 5a or 5b — a US shareholder of a CFC.
- Categories 2 and 3 — officers, directors and shareholders in the year shares are acquired.
A sole American owner is normally Category 4 and 5a together, which means close to the full form: Schedules E, G-1, H, I-1, J, M, P, Q and R. The IRS sets out the matrix in its Instructions for Form 5471, and our guide to Form 5471 filing requirements maps the categories to typical ownership.
The penalty for failure is $10,000 per form per year, with further penalties after IRS notice and a separate reduction of foreign tax credits under section 6038(c). A missing Form 5471 also keeps the statute of limitations open on the whole return under section 6501(c)(8).
The UAE side: the 30 September 2026 deadline
Under Federal Decree-Law No. 47 of 2022, a UAE corporate tax return and any tax due are generally due within nine months of the end of the tax period. For a financial year ending 31 December 2025, that is 30 September 2026, filed through EmaraTax — even where no tax is payable. The Federal Tax Authority's official portal carries the current guidance.
The headline rates are 0% on taxable income up to AED 375,000 and 9% above it. A Qualifying Free Zone Person pays 0% on qualifying income, but only if every condition is met — including a de minimis limit under which non-qualifying revenue must not exceed the lower of AED 5 million or 5% of total revenue. Fail a condition and 9% applies to all income. If you are still at the registration stage, see the UAE corporate tax registration deadline.
When UAE tax is paid, it only partly helps
Suppose the company fails the qualifying tests and pays 9% on all its income. Under a section 962 election, 90% of that tax is deemed paid, so the credit is roughly 8.1% of the profit against a US charge of about 12.6%. A residual US liability of roughly 4.5% remains. Failing the free zone test therefore costs 9% in the UAE and still leaves US tax to pay.
Reporting beyond Form 5471
- FBAR for the company's UAE bank accounts, where you own more than 50% or can sign on them — see FBAR and FATCA reporting.
- Form 8938 for the shares, once the specified foreign financial asset thresholds are met.
- Form 926 when you capitalise the company, in the circumstances set out in section 6038B.
- Personal UAE accounts count towards the same FBAR aggregate.
If you never filed
Delinquent Form 5471s are one of the most common reasons Americans in the Gulf come to us. Where the failure was non-willful, the streamlined procedures cover the missing information returns alongside the tax returns, with no penalty for filers who qualify as living abroad. Settle the disclosure route before preparing anything, because it decides how many years you file.
Tranzesta prepares the US and UAE sides together, so the section 962 decision is modelled against the company's actual free zone position rather than assumed. If you own a UAE company and hold a US passport, book a consultation before 30 September.
Frequently Asked Questions
Do I need to file Form 5471 for my Dubai free zone company?
Yes, if you are a US citizen or Green Card holder who owns or controls it. A sole American owner is normally a Category 4 and Category 5a filer, which means close to the complete Form 5471 every year. The UAE's 0% corporate tax rate has no bearing on the US filing obligation, and the penalty for failing to file is $10,000 per form per year.
Is income from a UAE free zone company taxable in the US?
Usually, even if nothing is distributed. A UAE company controlled by US shareholders is a controlled foreign corporation, so its passive and related-party income is taxed under subpart F and most trading profit under the NCTI regime from 2026. Because a qualifying free zone company pays no UAE tax, there is no foreign tax credit to reduce the US charge.
Should I make a section 962 election for a UAE company?
Often, but it needs modelling. The election taxes the NCTI inclusion at about 12.6% instead of ordinary rates of up to 37%, but profits distributed later are taxed again to the extent they exceed the tax already paid. Because there is no US–UAE tax treaty, those dividends are not qualified dividends, so the second layer is at ordinary rates.
When is the UAE corporate tax return due for the 2025 financial year?
Within nine months of the end of the tax period under Federal Decree-Law No. 47 of 2022. For a company whose financial year ended on 31 December 2025, the return and any tax due must be filed through EmaraTax by 30 September 2026 — including companies that expect no liability, such as qualifying free zone persons.
Are dividends from a UAE company qualified dividends in the US?
Generally not. Qualified dividend treatment for a foreign corporation requires a comprehensive US income tax treaty, incorporation in a US possession, or shares readily tradable on a US exchange. The UAE has no income tax treaty with the United States, so dividends from a private UAE company are taxed at ordinary rates of up to 37%.
I live in the UK and own a UAE company. What changes?
A second set of UK rules applies alongside the US ones. If the directors take decisions from London, the company can become UK tax resident under the central management and control test. Separately, the UK transfer of assets abroad rules can attribute the company's income to a UK-resident owner, so a UAE structure can be taxed in all three countries if it is not run carefully.
