Introduction: The E-1 Treaty Trader Visa and Two Tax Systems
An E-1 treaty trader visa lets a British business owner live in the United States to run trade between the two countries, and it quietly places both the owner and the company inside the US tax system. The immigration guides explain substantial trade, the 50% test and the embassy interview. However, none of the leading pages mentions a tax return. For an owner with a profitable UK company, that omission can cost six figures.
The E-1 treaty trader visa has a feature that few other US work visas share. Its rules require the trade to keep flowing between Britain and America. Consequently, you cannot simply close the UK business and start again in the United States. You will run a British company and an American presence side by side for as long as the visa lasts. Two corporate tax systems and two personal tax systems therefore apply at once.
At TaxYork, we prepare US and UK returns for owners who make this move. This guide covers what the visa pages leave out. It explains when you become a US tax resident, what happens to your UK company, how the two countries tax the trade, and which forms carry the heaviest penalties.
E-1 Treaty Trader Visa Rules That Shape the Tax Position
How the E-1 Treaty Trader Visa Works for UK Nationals
The E-1 treaty trader visa is a US non-immigrant status for nationals of countries that hold a commercial treaty with the United States. The UK qualifies under a convention that entered into force on 3 July 1815. USCIS sets out the conditions on its page for E-1 treaty traders. You must be a national of the treaty country, carry on substantial trade, and carry on that trade principally between the United States and your own country.
The practical terms of an E-1 treaty trader visa are attractive. The application fee is $315, and UK applicants can receive a visa valid for up to five years. Each entry normally grants a two-year stay, and extensions run in two-year periods without a fixed limit. Furthermore, a spouse may work in the United States without a separate permit, and unmarried children under 21 may accompany you.
The 50% Trade Test Is a Tax Constraint
Two 50% tests sit inside the E-1 treaty trader visa rules. First, more than 50% of the trader's international trade must be between the United States and the UK. Second, the trading business must be at least 50% owned by UK nationals. USCIS also confirms that substantial trade has no minimum value, although it requires a continuous flow of transactions.
These tests bind your tax structure. A British owner cannot move all the profit into a US company that sells only to American customers, because the cross-border flow would stop. Similarly, selling a majority stake to US investors can end the status. Therefore, every restructuring on an E-1 treaty trader visa must satisfy the immigration tests and the tax rules together.
The Old Treaty and the Residence Condition
The 1815 convention behind the E-1 treaty trader visa carries a condition that surprises many applicants. The State Department's guidance limits the treaty to British territory in Europe and to people who reside there actually and permanently. A British passport is necessary, but it is not always sufficient. A UK national who has lived in Dubai or Singapore for years can therefore face difficulty.
That condition matters for tax planning. Some owners leave the UK for a low-tax country before a US move, hoping to break UK residence early. That step can undermine the visa application itself. We describe the same trap for investors in our guide to E-2 visa tax for UK investors.
Owners and Employees
The E-1 treaty trader visa covers more than the owner. An employee of the trading business can also qualify if he or she holds UK nationality and works in an executive or supervisory role, or has essential skills. As a result, a UK company can send a senior manager to America on the same route. The tax issues below apply to that employee as well, although the company issues weigh most heavily on the owner.
When You Become a US Tax Resident
The Substantial Presence Test
US tax residence does not depend on holding an E-1 treaty trader visa. It depends on days. Under the substantial presence test, you become a US resident once you spend at least 31 days in the current year and 183 weighted days over three years. The formula counts every day in the current year, one third of the days in the previous year and one sixth of the days in the year before.
Some visa holders can exclude their days. Students, teachers and diplomats are exempt individuals for this purpose. However, the holder of an E-1 treaty trader visa is not. Every day in the United States counts from the first arrival, including earlier business trips. Most owners therefore become US residents in the year they move.
Your Residency Start Date
Your first year on an E-1 treaty trader visa is usually a dual-status year. You are a non-resident until your first day of presence in the year you meet the test, and a resident afterwards. The United States taxes only US-source income in the first part and worldwide income in the second. Our guide to the dual-status tax year explains how the two halves fit on one return.
The date matters because of what you do around it. A dividend from your UK company, a share sale or a bonus taken before the start date falls outside US tax. The same payment a week later is fully taxable. Accordingly, the weeks before departure deserve more care than any other period. We set out the steps in our article on pre-immigration tax planning for Britons moving to the US.
The Closer Connection Exception and the Treaty
Two escapes exist, and neither helps most owners on an E-1 treaty trader visa. The closer connection exception applies only if you spend fewer than 183 days in the United States in the year and keep your tax home abroad. You claim it on Form 8840. An owner who has moved the family to Boston will not qualify.
The treaty offers a second route. If both countries treat you as resident, Article 4 of the US-UK double taxation convention applies tie-breaker tests based on your permanent home and centre of vital interests. Nevertheless, an owner who relocates fully will usually break UK residence in any case. The treaty matters mainly in the year of the move and for commuters.
Worldwide Income From the Start Date
Once you are resident, the United States taxes everything. UK rental income, UK bank interest, dividends from your own company and gains on UK shares all go on Form 1040. In addition, UK ISAs lose their tax-free status for US purposes, and UK funds usually count as passive foreign investment companies. British wrappers that worked well at home often become liabilities in America.
Your UK Company After You Move
The Company Becomes a Controlled Foreign Corporation
This is the point that guides to the E-1 treaty trader visa never raise. When a US tax resident owns more than 50% of a foreign company, that company is a controlled foreign corporation under section 957 of the Internal Revenue Code. Your UK limited company therefore changes status on the day you become US resident, although nothing changes in Britain. You must then file Form 5471 with your return every year. The penalty for a missed form starts at $10,000.
The rules for an E-1 treaty trader visa make this almost unavoidable. The status requires continuing UK ownership and continuing UK trade. An owner who keeps the British company, as the visa expects, will hold a controlled foreign corporation for the whole stay.
Tax on Profits You Have Not Drawn
Ownership brings more than a form. US shareholders of a controlled foreign corporation are taxed each year on most of its profit, whether or not it pays a dividend. From 2026 this regime is called net CFC tested income. An individual who does nothing can face US tax at rates up to 37% on the company's retained profit.
Two reliefs usually solve the problem, but you must claim them. A section 962 election lets an individual be taxed at the 21% corporate rate, with a 40% deduction and a credit for 90% of the UK corporation tax paid. Because the UK main rate is 25%, that credit normally removes the US charge. Alternatively, a high-tax exclusion may apply. Our guide to Form 8992 for UK company owners explains the calculation.
Where the Company Is Resident
A UK-incorporated company remains UK resident wherever its director lives. HMRC confirms the incorporation rule in its company residence guidance. Your move therefore does not take the company out of UK corporation tax at 25%. However, it can create a second taxable presence in America, which is the next problem.
How America Taxes the Trade Itself
Permanent Establishment Under the Treaty
A UK company that merely sells to American customers owes no US federal income tax on its profits. Article 7 of the treaty allows the United States to tax business profits only where the company has a permanent establishment there. Article 5 defines that term to include a place of management, a branch and an office. It also covers a dependent agent who habitually concludes contracts in the company's name.
An owner living in America on an E-1 treaty trader visa changes the analysis. If you manage the UK company from a US office, or sign its contracts there, the company may have a permanent establishment. The profit attributable to that presence then becomes taxable in the United States. The IRS describes the underlying concept in its guidance on effectively connected income.
A US Branch
One structure accepts that result openly. The UK company registers a US branch and employs you through it. The branch's profit is taxed at the 21% federal corporate rate on Form 1120-F. In addition, a branch profits tax can apply when profits leave the branch, although the treaty reduces it to 5% and removes it for many qualifying companies.
A branch has drawbacks. The whole UK company stands behind its US liabilities, and the split of profit between head office and branch invites dispute. Furthermore, a UK company that files no US return can lose its right to deductions. Many owners therefore file a protective return even when they believe no permanent establishment exists.
A US Subsidiary
The more common structure for an E-1 treaty trader visa business is a US subsidiary. The UK company forms a US corporation, which buys from or acts for its parent and employs you. The subsidiary pays 21% federal tax on its own profit. Dividends back to a UK parent that owns at least 80% can qualify for a 0% treaty withholding rate, and otherwise 5% applies to substantial holdings.
Reporting is strict. A US corporation that is at least 25% foreign-owned must file Form 5472 for transactions with its foreign parent. The penalty is $25,000 for each failure. Our article on Form 5472 for UK owners covers the detail.
Transfer Pricing on the Trade Flow
The price between parent and subsidiary decides where profit is taxed. The United States expects an arm's length price, and so does the UK for larger groups. The trade that qualifies you for the E-1 treaty trader visa is therefore the same flow that both tax authorities will examine. You should document how you set that price before the first shipment. We discuss the rules in our guide to transfer pricing for US-UK business owners.
State Taxes Sit Outside the Treaty
The treaty binds the federal government only. States apply their own tests, and many tax a company that exceeds a sales threshold without any office. A British exporter can therefore owe state income tax or sales tax while owing no federal tax. Notably, the state where you settle also taxes your personal income under its own residence rules.
The UK Side of Your Return
Leaving UK Tax Residence
Your UK position after obtaining an E-1 treaty trader visa turns on the statutory residence test, which HMRC explains in its RDR3 guidance. An owner who works full-time abroad and limits UK days and UK workdays can become non-resident. Split-year treatment can then divide the year of departure. However, an owner who returns often to run the UK business can remain UK resident without intending to.
UK Income That Remains Taxable
Non-residents still pay UK tax on some income. Salary for duties performed in the UK remains taxable. UK rental income also stays within the charge, usually through the non-resident landlord scheme. In contrast, a non-resident's UK tax on dividends from a UK company is usually limited to nil under the disregarded income rules in section 811 of the Income Tax Act 2007. The United States will tax those dividends instead once you are resident there.
The Five-Year Return Trap
The UK has a rule for people who leave briefly. If you return within five years, certain income and gains received while you were away are taxed in the year you come back. Dividends from your own company out of pre-departure profits are a prime example. Gains on assets you owned before leaving are another.
This rule fits the E-1 treaty trader visa closely. The status is temporary, and you must intend to leave America when it ends. Many owners therefore return within five years and meet the charge. Our guide to temporary non-residence explains the mechanics. Planning dividends around both this rule and your US start date is essential.
National Insurance or US Social Security
Only one country should collect social security from an E-1 treaty trader visa holder. Under the US-UK totalisation agreement, an employee sent by a UK employer for up to five years can stay in UK National Insurance with a certificate of coverage. An owner hired directly by a US subsidiary pays US social security instead. The HMRC guidance on National Insurance when working abroad describes the certificate. The choice affects both cost and your future UK state pension record.
Reporting That Starts in Year One
FBAR and Form 8938
A US resident on an E-1 treaty trader visa must report foreign accounts. You file an FBAR when your non-US accounts together exceed $10,000 at any time in the year, as FinCEN explains on its page for reporting foreign bank and financial accounts. Business accounts on which you can sign also count. A missed FBAR in the first year is the most common error we see among new arrivals.
Form 8938 applies as well. For a single US resident, the threshold is $50,000 of foreign financial assets at year-end or $75,000 at any time, according to the IRS page for Form 8938. Shares in your own UK company count towards it. Our FBAR and FATCA reporting service covers both forms.
Pensions and ISAs
UK pensions need attention, not alarm. The treaty generally protects growth inside a UK pension from US tax, and it can allow relief for continuing contributions. ISAs receive no such protection. You should therefore review ISA holdings before your US start date, because gains realised afterwards are taxable in America.
The Green Card Question
The E-1 treaty trader visa gives no direct path to permanent residence. Owners who later obtain a green card change their tax profile. Treaty protections reserved for non-citizens can fall away, and long-term holders can face the US expatriation tax on leaving. In contrast, an owner who holds only an E-1 treaty trader visa can depart without that charge.
Case Study: A British Exporter Moves to Boston
Oliver owns all the shares in a UK company that makes specialist audio equipment. Turnover is £3 million, and 65% of sales go to American customers. He obtains an E-1 treaty trader visa and moves to Boston in July 2026. The UK company forms a US subsidiary, which distributes the products and employs him on a salary of $250,000.
The corporate position is orderly. The subsidiary earns $400,000 and pays federal tax of $84,000 at 21%. The UK company keeps a profit of £350,000 and pays UK corporation tax of £87,500 at 25%. The subsidiary files Form 5472 for its purchases from the parent, and the group documents its transfer price.
Oliver's personal position is where the risk sat. From his arrival date he is a US resident, so the UK company is a controlled foreign corporation. Its retained profit of £350,000 is about $465,500 at $1.33 to the pound. Without an election, that profit could be taxed on his personal return at rates up to 37%, which is roughly $172,000. He had drawn none of it.
Preparation removed the charge. We filed Form 5471 and made the section 962 election, and the credit for UK corporation tax eliminated the US tax on the company's profit. Oliver had also taken a £200,000 dividend in June, before his US start date, so the United States did not tax it. Finally, he filed an FBAR for his UK accounts. The saving against the unplanned outcome exceeded $170,000 in the first year alone.
How TaxYork Can Help
TaxYork prepares the full set of returns for British owners on an E-1 treaty trader visa. We establish your US residency start date, prepare the dual-status return, and file Form 5471, Form 8992, the FBAR and Form 8938. Additionally, we prepare your UK return for the year of departure and for any UK income that continues.
We also work on the structure before you travel. That covers the branch or subsidiary decision, the section 962 election, dividend timing and the treaty position, which our tax treaty optimisation service coordinates. Where earlier years contain missed US tax returns or a missed FBAR, we bring them up to date through US tax return preparation for expats and related filings.
Conclusion
An E-1 treaty trader visa is an efficient way for a British owner to build an American market in person. Its conditions keep your UK company alive, and that is exactly what creates the tax complexity. You become a US resident by counting days, your UK company becomes a controlled foreign corporation, and the trade between the two countries faces scrutiny from both authorities.
None of this is a reason to avoid the route. It is a reason to prepare. You should fix your US start date, your dividend timing and your company structure before you leave. Furthermore, you should make the right elections in the first return and file every information form on time. Ultimately, the owners who plan before the embassy interview pay tax once, and the others often pay it twice.
