Introduction: F-1 Visa Tax for British Families With a Student in America
F-1 visa tax is the combined US and UK tax position of a British student who studies at an American university on an F-1 visa. Most families assume the subject is trivial. After all, the student earns little, and the parents pay the fees from London. However, the rules reach much further than a campus pay cheque, and they bite hardest where the student already holds wealth.
Many British students at American universities come from families with substantial assets. They hold a six-figure ISA built from a Junior ISA. They own shares in the family company. Their parents open an American brokerage account for them in the first term. As a result, their F-1 visa tax position looks nothing like the one the standard student guides describe.
Most guides to F-1 visa tax explain Form 8843, mention a refund and stop. Consequently, they never mention HMRC, the 30% charge on capital gains or the reporting cliff in year six. This guide covers all of them with 2026 figures and a worked case study. At TaxYork, we prepare US and UK returns for families moving in both directions, so we see the F-1 from both sides of the Atlantic.
What F-1 Visa Tax Actually Covers
The F-1 is the standard visa for full-time academic study in America. It permits limited campus work, internships and a period of work after graduation. Therefore, F-1 visa tax has five layers. First, there is the question of when the student's days start counting towards US residence. Second, there is US tax on wages, scholarships and investments. Third, there is social security. Fourth, there is state income tax. Finally, there is what HMRC still taxes, which depends on how many days the student spends back in Britain.
Why Wealthy Families Face a Different Problem
A student with no assets has a simple F-1 visa tax position. In contrast, a student with investments has three problems that the campus tax workshop never raises. Specifically, a sale of shares can cost 30% in America, even where the shares are British. Moreover, UK residence can switch on and off from one year to the next. Above all, the student becomes a full US tax resident after five calendar years, and every UK account then becomes reportable.
When an F-1 Student Becomes a US Tax Resident
A visa does not make anyone a US tax resident. Days do, and F-1 visa tax starts with counting them. However, an F-1 student may ignore those days for a limited time, and that single rule drives every other F-1 visa tax decision.
The Five Calendar Year Rule
Under the IRS substantial presence test, a person is a US resident after 31 days in the current year and 183 days under a weighted three-year formula. An F-1 student, however, is an "exempt individual" whose days do not count. The IRS guidance on the exempt individual rules for students limits that status to five calendar years.
The phrase "calendar years" matters. A student who arrives in late August uses a whole exempt year in four months. For example, an arrival in August 2022 uses 2022, 2023, 2024, 2025 and 2026. Accordingly, the student becomes a US resident on 1 January 2027, usually during the first year of work after graduation. Furthermore, the five years are a lifetime allowance. An earlier school exchange or a previous J-1 summer counts against it.
Form 8843 and the Annual F-1 Visa Tax Filing
Every exempt student files Form 8843 each year, even with no income at all. The form tells the IRS why the student's days should not count. If the student has US wages, the form goes with Form 1040-NR by 15 April. Otherwise, a standalone Form 8843 is due by 15 June. For the 2026 calendar year, those dates fall on 15 April 2027 and 15 June 2027.
Compliant F-1 visa tax filing also protects the visa. Consular officers and employers ask for tax records later, particularly at the green card stage. Therefore, a missing Form 8843 is cheap to file and expensive to explain.
Staying Exempt Beyond Five Years
A student can remain exempt after five calendar years, but only in narrow cases. The student must show no intention to reside permanently in America and substantial compliance with the visa. In practice, the IRS looks at whether the student keeps a closer connection to a foreign country and whether any step towards permanent residence has begun. Consequently, a doctoral student who plans to return to Britain may qualify, whereas a graduate with a green card petition will not. Our guide to the closer connection exception for UK nationals explains the related test.
The 2026 Fixed Admission Rule
In July 2026, the Department of Homeland Security published a final rule replacing duration of status with a fixed period of admission. It would cap F-1 admission at four years and cut the grace period after graduation from 60 days to 30. However, a federal court in Massachusetts issued a nationwide preliminary injunction on 14 September 2026, the day before the rule took effect. The old framework therefore remains in place while the litigation continues.
The rule does not change the tax law. Nevertheless, it matters for planning. A student whose status lapses stops being an exempt individual, and days start counting at once. For that reason, families should confirm the current position with the university's international office before each academic year.
What America Taxes While the Student Is a Nonresident
During the exempt years, F-1 visa tax follows the nonresident alien rules, so America taxes only US-source income. Parental support from Britain, UK dividends and UK bank interest fall outside the American net during the exempt years. However, four categories of US income deserve attention.
Wages From Campus Jobs and Internships
Campus work, a summer internship and post-graduation employment all produce US wages. Those wages face tax at ordinary graduated rates, which for 2026 run from 10% on the first $12,400 to 22% above $50,400. Importantly, a nonresident alien receives no standard deduction and cannot file jointly. Similarly, the education credits linked to Form 1098-T belong to residents only.
The US-UK treaty offers no help with this part of F-1 visa tax. Some treaties exempt a slice of student wages, and several online guides wrongly list one for Britain. In fact, Article 20 of the UK treaty covers only payments that arise outside America for maintenance, education or training. The IRS confirms the position in Publication 901 on US tax treaties. Thus a British student pays federal tax on every dollar of wages.
Scholarships and Fellowship Grants
A scholarship that pays tuition, required fees and books is tax-free for a degree student. In contrast, any part that covers room, board or living costs is taxable. Where the grant comes from an American source, the university withholds 14% and reports it on Form 1042-S, as the IRS explains in its guidance on withholding on scholarships paid to foreign students. Accordingly, a generous athletic or merit award with a housing element creates a filing obligation even where the student never works.
The 30% Capital Gains Trap in F-1 Visa Tax
This is the F-1 visa tax rule that catches wealthy families. Most nonresidents pay no US tax on share sales. However, section 871 of the Internal Revenue Code imposes a flat 30% tax on net US-source capital gains where a nonresident is present in America for 183 days or more in the tax year. A full-time student is almost always present for more than 183 days. Notably, this day count has nothing to do with the exempt individual rule, so exempt days still count here.
The sourcing rule then makes matters worse. A gain on shares takes its source from the seller's tax home. According to the IRS guidance on capital gains of nonresident alien students, most foreign students shift their tax home to America on the day they arrive. Consequently, a gain on British shares, or on funds sold inside an ISA, can count as US-source. The student then owes 30% on a gain that Britain treats as tax-free.
Only the treaty rescues the position. Under Article 13 of the UK-USA double taxation convention, most gains are taxable only in the country where the seller is resident. Therefore, a student who remains UK resident under British law pays nothing to the IRS on the sale. A student who has lost UK residence has no treaty protection at all. This single point makes the UK residence test the centre of F-1 visa tax planning for any family with investments.
Dividends, Interest and the Brokerage Account
American dividends face 30% withholding, which the treaty cuts to 15% for a UK resident who gives the broker Form W-8BEN. Interest on an ordinary American bank deposit, however, is exempt for nonresidents. Meanwhile, the treaty rate depends on the same residence question. If the student has ceased to be UK resident, the 15% rate is no longer available, and the form on file with the broker is wrong.
Social Security, OPT and State Tax
Wages bring two further F-1 visa tax charges beyond federal income tax. One of them is usually exempt, and employers often get it wrong.
The FICA Exemption for F-1 Students
A nonresident F-1 student pays no Social Security or Medicare tax on authorised work. The IRS page on foreign student liability for Social Security and Medicare taxes confirms that the exemption covers campus jobs, authorised off-campus work and practical training. It saves 7.65% of wages. However, it ends on the day the student becomes a resident alien.
Employers outside the university sector often withhold these taxes by mistake. In that case, the student first asks the employer for a refund. If the employer refuses, the student claims from the IRS on Form 843 with Form 8316. In our experience, this is the most common F-1 visa tax refund, and many graduates never claim it.
Optional Practical Training After Graduation
Most graduates stay to work under Optional Practical Training, which lasts twelve months. Science, technology, engineering and mathematics graduates can add a further 24 months. The student remains in F-1 status throughout. Therefore, OPT wages stay free of FICA for as long as the five exempt calendar years last.
The F-1 visa tax arithmetic matters for a graduate entering finance or technology. For instance, a four-year degree that begins in August uses four and a half calendar years on campus. The fifth exempt year therefore ends about seven months into the first job. Subsequently, the graduate pays FICA and files as a resident. A move to an H-1B visa ends exempt status even sooner, as our guide to H-1B visa tax for British professionals explains.
State Income Tax
State tax is the layer of F-1 visa tax that follows its own rules. Massachusetts taxes wages at 5%, New York and California charge more, and Texas and Florida charge nothing. Furthermore, some states do not follow federal treaties, so a treaty exemption for gains or dividends may not carry through to the state return. Many states also define residence differently from the IRS. As a result, a student can be a nonresident alien federally and a state resident at once.
What HMRC Still Taxes While the Student Is in America
British families often assume that a student in America has left the UK tax system. Usually, the student has not. This is the part of F-1 visa tax that the American guides ignore entirely.
The Statutory Residence Test for a Student Abroad
HMRC decides residence under the statutory residence test, set out in the RDR3 guidance note. The test that removes most expatriates from UK residence requires full-time work overseas. Study does not count as work. Therefore, a student relies on the day-count tests instead.
A student who spends fewer than 16 days in Britain in a tax year is automatically non-resident. Almost no undergraduate meets that limit. Otherwise, residence depends on days and ties. A typical student has two ties. The first is accommodation, because a bedroom at the parents' home counts once the student spends 16 nights there. The second is the 90-day tie, which looks back at the two previous tax years.
With two ties, a student who spends 91 days or more in Britain remains UK resident. With 90 days or fewer, the student is non-resident. Christmas, a spring break and a full summer at home usually exceed 91 days. In contrast, a summer internship in New York usually keeps the total below it. Consequently, UK residence can switch off in an internship year and back on the next, and the family rarely notices.
What UK Residence Means for the Student
A UK-resident student pays UK tax on worldwide income, as the HMRC guidance on residence and foreign income confirms. That includes American wages, with credit for US tax paid. The personal allowance of £12,570 covers a campus job, but not an investment banking internship. Similarly, gains on the American brokerage account fall within UK capital gains tax at 18% or 24%, after the £3,000 annual exempt amount.
Nevertheless, UK residence has real value in F-1 visa tax planning. It keeps the treaty rate on dividends at 15%. More importantly, it switches off the 30% American charge on gains. A UK-resident student who sells investments inside an ISA pays nothing in either country. Hence the F-1 years, used carefully, are the cheapest time to reorganise a portfolio.
Temporary Non-Residence on Return
A student who becomes non-resident should not treat that as an opportunity to sell assets free of UK tax. Under the temporary non-residence rules described in the HMRC Capital Gains Manual, gains on assets held before departure become taxable in the year of return where the absence lasts five years or less. In addition, the 30% American charge applies in the meantime. A sale during a non-resident year can therefore suffer tax in both countries, with relief only for the overlap.
ISAs and UK Accounts During the F-1 Years
A non-resident cannot subscribe new money to an ISA, although existing ISAs stay open and keep their UK exemption under the ISA rules. While the student remains a nonresident alien, the IRS has no interest in the ISA's income. However, sales inside the ISA fall within the 30% rule above unless the treaty applies. The wrapper means nothing to the IRS.
Year Six: When UK Wealth Becomes Reportable in America
The sixth calendar year changes everything. From 1 January, the former student is a US tax resident on worldwide income. For a wealthy family, this is the most expensive moment in F-1 visa tax, and it arrives without any letter or warning.
Worldwide Income and the ISA
At this point, F-1 visa tax gives way to full resident taxation. A resident alien files Form 1040 and reports all income from every country. The ISA loses its shelter, because America does not recognise it. Moreover, most UK funds and investment trusts are passive foreign investment companies. Each one needs Form 8621 every year, and gains face punitive rates with an interest charge. Therefore, a portfolio that was sensible for a London teenager becomes a liability for a New York analyst.
FBAR, Form 8938 and Missed Reporting
Residence also triggers information reporting. A US resident with foreign accounts above $10,000 in aggregate at any point in the year must file an FBAR, as the FinCEN guidance on reporting foreign bank and financial accounts sets out. The report is due on 15 April with an automatic extension to 15 October. Additionally, Form 8938 applies to a single US resident whose foreign financial assets exceed $50,000 at year end or $75,000 at any time.
A stake of 10% or more in the family company can require Form 5471. Likewise, family funding from abroad above $100,000 in a year must go on Form 3520, although it remains free of income tax. A missed FBAR can cost more than $16,000 per report, even where the failure was non-wilful. In our experience, graduates in year six miss all of these, because their employer's payroll team sees only the salary. Our FBAR and FATCA reporting service deals with both current and late filings.
The Treaty Tie-Breaker
A graduate who is resident in both countries can look to the treaty's tie-breaker in Article 4. However, a graduate working full-time in America with a home there will rarely win it. Furthermore, a successful claim brings its own disclosure on Form 8833 and can damage a later green card application. Accordingly, we treat the tie-breaker as a last resort rather than a plan. Our guide to the substantial presence test for Britons covers the day counting in detail.
Reorganising Before the Sixth Year
F-1 visa tax planning before the cliff is straightforward. The family should sell or switch fund holdings while the student is still a nonresident alien, and ideally in a year of UK residence. As a result, the treaty removes the 30% charge, the ISA removes UK tax, and the portfolio enters year six free of passive foreign investment companies. Timing is everything, because the same sale one year later falls within the full American regime.
The Filing Mistakes We See Most Often
Most F-1 visa tax errors come from treating the student as an ordinary American taxpayer, or as no taxpayer at all.
Filing as a Resident by Mistake
Mainstream American tax software prepares Form 1040, not Form 1040-NR. A student who uses it files as a resident and claims a standard deduction and credits that nonresidents cannot have. Consequently, the refund is too large, and the return is wrong. The student must amend it, and the error sits on the record that immigration officers later review. Publication 519, the US tax guide for aliens, sets out the correct form for each status.
Ignoring the Investment Account
Standard F-1 visa tax tools ask about wages and scholarships. They rarely ask about share sales, and they never ask about days spent in Britain. Therefore, the 30% charge on gains goes unreported in many wealthy families. Similarly, the broker continues to apply the 15% treaty rate to dividends after the student has ceased to be UK resident.
Forgetting the UK Return
A UK-resident student with American wages above the personal allowance, or with gains above £3,000, needs a UK self assessment return. Parents often assume their own adviser has it covered. Usually, nobody does. Missed UK tax returns are the quiet half of F-1 visa tax, and they surface years later, when the graduate returns to London and registers for self assessment.
An F-1 Visa Tax Case Study With Real Numbers
The following illustrative case brings the F-1 visa tax rules together. The client is a composite, and the figures are rounded.
The Position
Imogen R grew up in London and began a four-year degree at a Boston university in August 2022. Her parents paid fees and living costs of about $85,000 a year from Britain. She held a stocks and shares ISA worth £210,000, invested in twelve UK funds, with an unrealised gain of £70,000. In 2023, her parents also funded an American brokerage account in her name with $200,000.
In summer 2024, she took an internship in New York. As a result, she spent only 58 days in Britain in the 2024-25 UK tax year. With two ties, she needed 91 days to remain UK resident, so she became non-resident for that year. In October 2024, she sold American shares at a gain of $38,000.
What the Missed Rule Cost
Imogen was present in America for about 300 days in 2024, which is where her F-1 visa tax problem began. Therefore, the 30% charge applied, and she had no treaty protection because she was not UK resident when she sold. The tax came to $11,400. Moreover, her broker had withheld only 15% on $4,000 of dividends paid after April 2024, which left a further $600 due. Her student tax software had reported her internship wages and nothing else.
Without action, the larger problem lay ahead. Her five exempt years ended on 31 December 2026. From 1 January 2027, she would owe FICA of about $8,415 on a $110,000 graduate salary. She would also need twelve Forms 8621, an FBAR and Form 8938, with punitive tax on any later sale of the ISA funds.
What We Changed
The family came to us in late 2025. We prepared an amended 2024 Form 1040-NR and paid the $12,000 with interest before the IRS raised the point. We then counted her UK days for 2025-26. She had spent the summer of 2025 at home and reached 97 days, so she was UK resident for that year.
In February 2026, she switched the ISA from funds into directly held shares and gilts. The £70,000 gain was free of UK tax inside the ISA. It was also free of US tax under Article 13, which we disclosed on Form 8833 with her 2026 return. In the same UK tax year, she sold the remaining brokerage positions at a gain of about £24,000. That cost roughly £3,800 in UK capital gains tax at 18%, against about $9,000 under the American 30% rule. Ultimately, she entered 2027 with no passive foreign investment companies, a clean filing record and a calendar for her first FBAR.
How TaxYork Can Help
TaxYork provides F-1 visa tax return preparation for British students, graduates and their families. We file Form 8843 and Form 1040-NR each year, alongside the UK self assessment return where the student remains UK resident. Furthermore, we count days on both sides, so the treaty position on gains and dividends is correct before any sale takes place.
For wealthy families, we also prepare for year six. That includes restructuring ISAs and fund holdings, and setting up FBAR, Form 8938 and Form 5471 reporting from the first resident year. Where filings were missed, we prepare late and amended returns with a clear explanation. Our US-UK treaty relief service and cross-border planning work bring both countries into one engagement. You may also find our guide to J-1 visa tax for British academics useful if a research post follows the degree.
Conclusion
F-1 visa tax looks simple for a student with a campus job and nothing else. For a student with an ISA, a brokerage account or a stake in the family business, it is one of the more technical areas of cross-border tax. The exempt years protect against worldwide taxation, but they do not protect against the 30% charge on gains. Meanwhile, HMRC applies its own day count, and the answer can change every year.
Therefore, the best time to plan your F-1 visa tax position is before the first term, and the last good time is before the fifth calendar year ends. Count the exempt years, track the days in Britain and reorganise the portfolio while the treaty still applies. Above all, treat the sixth year as a fixed deadline, because the IRS does.
