Introduction: What a UK Student Visa Means for an American Family's Tax
A UK Student visa lets an American study at a British university for up to five years, but it does nothing to pause the tax rules of either country. The United States continues to tax its citizens on worldwide income wherever they live. Meanwhile, Britain decides tax residence by counting days, not by reading visas. Consequently, a student with an investment account in their own name can become a UK taxpayer in the second term of the first year. For a family with real wealth, that matters far more than the part-time job most guides discuss.
The UK Student Visa in One Paragraph
The UK Student visa replaced the old Tier 4 route. You need an offer from a licensed sponsor, and the application costs £558 from outside the UK, plus the immigration health surcharge. Degree-level students can usually stay for up to five years. Furthermore, the visa limits work to 20 hours a week in term time for degree-level study, and it bans self-employment outright. After graduation, the Graduate visa adds two years if you apply by 31 December 2026, or 18 months if you apply from 1 January 2027. The Home Office sets out the full conditions in its Student visa guidance.
Why Wealthy Families Need a Different Guide
Most articles on UK Student visa tax address a student with a small wage and no assets. That is not our reader. The children of bankers, investors and company owners often hold brokerage accounts, company shares or a share of a family partnership. Moreover, the family may buy a London flat for the degree. Each of those facts creates a filing point in two countries. At TaxYork we prepare US and UK returns for American families in Britain, and this guide explains how the UK Student visa years actually work on both sides.
When a UK Student Visa Holder Becomes UK Tax Resident
For a UK Student visa holder, tax residence drives everything else. If the student is non-resident, Britain taxes only UK income. If the student is resident, Britain taxes worldwide income and gains unless a relief applies. HMRC's summary of UK residence and tax gives the outline, and the detail sits in the Statutory Residence Test guidance.
The 183-Day Test and the First Academic Year
Anyone who spends 183 days or more in the UK in a tax year is resident. The UK tax year runs from 6 April to 5 April. Therefore the first academic year straddles two tax years. A UK Student visa holder who arrives in mid-September has roughly 200 days available before 5 April. However, three weeks at home over Christmas can pull the count below 183. As a result, the first year is often borderline, and the answer depends on a calendar the family rarely keeps.
The Ties Test for a New Arrival
Below 183 days, the sufficient ties test decides. For someone who was not UK resident in any of the previous three tax years, two ties make them resident at 121 to 182 days. A UK Student visa holder usually has an accommodation tie, because halls or a flat are available for 91 days or more. Additionally, a work tie arises after 40 days of working three hours or more. In the first year the 90-day tie cannot apply, because it looks at earlier years. Consequently, a first-year student with no job and fewer than 183 days is often non-resident. From the second year, however, the 90-day tie applies automatically, and residence becomes close to certain. Our guide to the statutory residence test for US citizens explains each tie.
Why the Starting Year Matters So Much
The year in which residence begins starts a four-year clock for the main relief available to new arrivals. Therefore the difference between 180 days and 185 days in year one can decide whether relief covers the final year of the degree. Accordingly, we ask every student family for flight records from the first September onwards. Where residence begins part-way through a year, split year treatment may also apply.
How Britain Taxes a Student on a UK Student Visa
Once a UK Student visa holder is resident, three separate rules decide what Britain actually taxes. They overlap, and choosing between them is the core of the UK planning.
Money From Home and Article 20 of the Treaty
Family support is not income. Britain does not tax a student on money that parents send for fees and living costs. Furthermore, Article 20 of the US-UK treaty gives a specific protection. Payments that a student receives for maintenance, education or training are not taxed in the UK, provided they arise outside the UK and the student was a US resident immediately before arriving. Notably, the treaty's savings clause does not remove this benefit for a student who is neither a British citizen nor settled in the UK. The treaty text appears in the Double Taxation Relief (United States of America) Order 2002, and HMRC lists the documents on its USA tax treaties page. Scholarships and grants from American sources fall within the same article. However, Article 20 protects support payments. It does not exempt dividends, interest or gains on the student's own portfolio.
The Four-Year Foreign Income and Gains Regime
For the portfolio, the relevant relief is the foreign income and gains regime, which replaced the remittance basis on 6 April 2025. A new resident who was non-resident for the previous ten tax years can claim exemption for foreign income and gains for up to four tax years. HMRC explains the conditions in its guidance on the 4-year FIG regime. Importantly, the relief is not automatic. You must register for Self Assessment and claim it on a tax return each year. In addition, a claim costs you the personal allowance and the capital gains annual exempt amount for that year. Our guide to claiming the FIG regime on a UK tax return covers the mechanics.
Part-Time Wages, PAYE and National Insurance
The wages of a UK Student visa holder are taxed through PAYE in the ordinary way. The personal allowance is £12,570, and term-time earnings at 20 hours a week usually fall below it. HMRC's page on student jobs and paying tax confirms that students pay income tax and National Insurance on the same basis as anyone else. Here the FIG trade-off bites. If the student claims FIG relief, the personal allowance disappears, and every pound of wages becomes taxable at 20%. Therefore a claim that saves nothing on the portfolio can cost up to £2,514 on wages. Conversely, a claim that shelters a large gain is worth many times that. We run the comparison every year, because the answer changes with the facts.
Council Tax and the Family Flat
Full-time students are disregarded for council tax, as the guidance on discounts for full-time students explains. A property occupied only by students is exempt. However, a flat bought by the parents raises separate questions on stamp duty, on rental income if a flatmate pays rent, and on the eventual sale. Those points fall outside this article, and our cross-border planning service deals with them.
What the IRS Still Expects From an American on a UK Student Visa
Nothing about a UK Student visa changes the American position. The IRS guidance for US citizens and resident aliens abroad applies in full, and four rules matter for a student.
Filing Thresholds for a Dependent Student
A UK Student visa holder whom the parents claim as a dependent has a much lower filing threshold than an independent adult. For 2025, a dependent must file once unearned income exceeds $1,350. Therefore a student with even a modest brokerage account files a Form 1040 every year. An extension to 15 June applies automatically to taxpayers living abroad, but interest still runs from 15 April on any tax due.
The Kiddie Tax at the Parents' Rate
The larger issue is the kiddie tax. Under the IRS rules on tax on a child's investment income, a full-time student aged 19 to 23 falls within the regime if their earned income does not exceed half of their support. Unearned income above $2,700 is then taxed at the parents' marginal rate on Form 8615. For a wealthy family, that means 37% on interest and 20% on long-term gains and qualified dividends. Moreover, the 3.8% net investment income tax can apply on top. Consequently, moving assets into a student's name rarely saves US tax during the degree. Our guide to the kiddie tax for US-British families explains the calculation.
Wages, the Exclusion and the Credit
UK wages are US taxable income too. In practice, a student's wages usually sit below the US standard deduction, so no US tax arises. Where they exceed it, the foreign earned income exclusion can remove them, provided the student meets the physical presence test of 330 full days abroad in a 12-month period. Long summers in America often break that count. Alternatively, the foreign tax credit works only where UK tax was actually paid, which is rare on a student wage. Additionally, education credits remain available at eligible foreign universities under IRS Publication 970, although high-income parents usually exceed the income limits.
Your Home State May Still Tax You
An American who leaves California or New York on a UK Student visa normally remains a resident of that state. Both states treat an absence for study as temporary. California's guidance on residency status makes the point directly. Therefore a gain realised during the UK Student visa years can attract state tax as well as federal tax, with no treaty protection at all. We explain the tests in our guide to US state tax residency after a move to London.
Accounts, Reporting and the Mistakes That Lead to Missed Filings
Reporting failures are more common than tax failures during the UK Student visa years. The amounts that pass through a student's account are large, even when the income is small.
FBAR: Tuition Money Counts
A UK Student visa holder who is a US person must file an FBAR if foreign accounts together exceed $10,000 at any time in the year. A single term's tuition and rent, paid into a UK current account, clears that figure in one transfer. FinCEN's guidance on reporting foreign bank and financial accounts sets out the rule. Furthermore, a parent who holds signature authority over the student's UK account has a separate FBAR obligation. A missed FBAR is the most frequent failure we see in student families, and it usually runs for the whole degree.
Form 8938 and UK Savings Products
A student living abroad files Form 8938 once specified foreign assets exceed $200,000 at year end or $300,000 at any time. Most students stay below that. However, UK banks routinely offer students an ISA, and a stocks and shares ISA holding UK funds creates passive foreign investment company reporting. Britain treats the ISA as tax-free, while the IRS taxes everything inside it. Therefore we recommend that American students decline investment ISAs entirely.
The Self-Employment Trap
The UK Student visa prohibits self-employment. Many American students continue freelance work for US clients, or run an online business, without realising that the visa forbids it. That is an immigration problem first, and you should take immigration advice on it. Nevertheless, it is a tax problem too, because the income needs reporting in both countries and can carry US self-employment tax. Accordingly, raise any side income with your preparer before the first UK return.
Putting Missed Years Right
Where a student has missed US returns or FBARs, the position is usually simple to repair. Non-wilful taxpayers living abroad can use the IRS Streamlined Filing Compliance Procedures, and our IRS Streamlined Filing service prepares the submission. On the UK side, late registration matters more than most families expect, because a FIG claim depends on a filed return. Our FBAR and FATCA reporting service handles the account reporting.
After Graduation: The Graduate Visa and the End of Relief
The tax position changes sharply when the UK Student visa ends. Families who plan only for the student years often meet the largest bill afterwards.
The Four-Year Clock Runs Out
The FIG regime lasts four consecutive tax years from the year residence begins. A three-year English degree leaves one year of relief. A four-year Scottish degree, or a degree followed by a master's course, uses all of it. Therefore a graduate who stays in London on the Graduate visa may face full UK tax on worldwide income and gains from the fifth year. Additionally, unused years cannot be carried forward, so a year in which no claim was made is simply lost.
Realise Gains Inside the Window
The practical consequence is timing. A gain realised in a FIG year, including a year on a UK Student visa, escapes UK tax if the student claims the relief. The same gain in year five faces UK capital gains tax at up to 24%. Consequently, a family that intends to sell concentrated holdings should consider doing so while relief remains. The US tax arises either way, so the decision turns on the UK side alone.
From Student to Employee
A graduate who takes a City job becomes an ordinary dual filer. UK tax on salary then exceeds US tax, and the foreign tax credit normally eliminates the US bill. However, the reporting grows, because workplace pensions and share awards arrive. We cover a parallel route in our guide to High Potential Individual visa tax for American graduates. British families facing the reverse journey can read our guide to F-1 visa tax for British students.
Case Study: An $80,000 Gain in the Second Year of a London Degree
The following illustration uses realistic figures. We have changed the details, and we use an illustrative rate of $1.32 to the pound.
The Starting Position
Madison is 20, a US citizen from New York and a second-year student on a three-year degree in London, holding a UK Student visa. Her father is a hedge fund partner in the top federal bracket. She holds a brokerage account in her own name, funded over many years, and she earns £9,000 a year from a term-time job. In her first year she spent 176 days in the UK and had no job, so she was not UK resident. In her second year she is resident, because the 90-day tie now applies. In October of that year she sells shares in a US technology company for a long-term gain of $80,000, or about £60,600.
The UK Result Without a Claim
Without a FIG claim, Madison keeps her personal allowance, so her wages bear no income tax. However, Britain taxes the gain. After the £3,000 annual exempt amount, £57,600 is chargeable. The first £37,700 falls in her basic rate band at 18%, which is £6,786. The remaining £19,900 is taxed at 24%, which is £4,776. Her UK capital gains tax is therefore £11,562.
The UK Result With a FIG Claim
With a claim, the foreign gain is exempt. She loses her personal allowance, so her £9,000 of wages is taxed at 20%, which costs £1,800. The claim therefore saves £9,762 in UK tax in a single year. Moreover, because her first year was non-resident, her four-year window starts in her second year and covers two further years after she graduates.
The US Result
The United States taxes the gain regardless. Because Madison is a full-time student under 24 and her wages are less than half her support, the kiddie tax applies. The gain is taxed at her father's 20% rate, plus the 3.8% net investment income tax, which comes to $19,040. New York also taxes the gain, because she remains a New York resident while she studies. Her wages fall below the standard deduction. Additionally, her UK current account peaked at £24,000 when her tuition instalment arrived, so she files an FBAR.
What We Prepared
We reconstructed her day count from flight records to confirm the first-year position. We then registered her for Self Assessment before the 5 October deadline, filed a UK return with the FIG claim, and prepared her Form 1040 with Form 8615, her New York return and her FBAR. The family had assumed that a UK Student visa holder with a £9,000 wage had nothing to file. In fact she had four filings, and one claim worth almost £10,000.
How TaxYork Can Help
TaxYork provides comprehensive tax preparation and compliance for high-net-worth American families with children at British universities on a UK Student visa. We track UK day counts, confirm the year in which residence begins and compare the FIG claim against the personal allowance each year. Furthermore, we prepare the student's UK Self Assessment return and US Form 1040 together, including Form 8615, state returns, the FBAR and Form 8938. Where a treaty position under Article 20 applies, our tax treaty service documents it. Where earlier years are missing, we bring both records up to date.
Conclusion
A UK Student visa governs what you may study and how much you may work. It does not govern tax. Britain treats most American students as resident from the second year at the latest, and the United States never stops taxing them. Family support is safe, and Article 20 of the treaty protects it. However, the student's own portfolio needs an active FIG claim, the kiddie tax applies the parents' rate in America, and the home state often keeps its claim. Therefore count days from the first September, register for Self Assessment in time, and review any planned sale against the four-year window. Above all, prepare the US and UK returns together.
