US–UK Tax Considerations for Americans Moving to the UK
Understand US and UK reporting, residence tests, foreign income relief and the interaction between tax credits and exclusions.
Moving to the UK can bring you within the British tax system without ending your US tax obligations. The practical challenge is understanding how the two systems interact—and arranging your affairs before a move, investment sale or other financial decision creates an unexpected result.
Three distinctions matter from the outset: filing a return is different from owing tax, UK residence is more nuanced than a 183-day count, and relief available in one country does not automatically remove tax in the other.
Your US Tax Obligations Continue After Moving
US citizens generally remain subject to federal income tax on worldwide income while living abroad. Whether you must file a return depends on the applicable filing requirements, including income, age and filing status.
Living in the UK does not, by itself, remove those requirements. Equally, it is too broad to say that every American abroad must file Form 1040, an FBAR and FATCA-related reporting every year: each has its own rules.
Form 1040: Reporting Worldwide Income
If you meet the filing requirements, your US return generally includes taxable income from both US and foreign sources.
You may then qualify for exclusions, credits or treaty treatment. Those mechanisms can reduce tax, but they do not mean the income can simply be omitted from the return.
The IRS specifically warns that claiming the Foreign Earned Income Exclusion still requires reporting the income and claiming the exclusion.
FBAR: A Separate Foreign Account Report
An FBAR is generally required when a US person has a financial interest in, or relevant authority over, foreign financial accounts whose combined value exceeds $10,000 at any point during the calendar year.
The threshold applies across reportable accounts—not separately to each account. A UK current account and savings account may therefore trigger reporting even if neither individually exceeds $10,000.
The FBAR is filed separately with FinCEN, rather than attached to Form 1040.
FATCA and Form 8938: Different Requirements
For individuals, the relevant FATCA-related filing may include Form 8938, covering specified foreign financial assets.
For qualifying taxpayers living abroad, the usual thresholds are:
- Single or married filing separately: more than $200,000 at year-end or $300,000 at any point during the year.
- Married filing jointly: more than $400,000 at year-end or $600,000 at any point during the year.
The higher overseas thresholds require meeting the applicable living-abroad conditions. Form 8938 and the FBAR are separate obligations; meeting one does not replace the other.
UK Tax Residence: Why 183 Days Is Not the Whole Test
Spending 183 days or more in the UK during a UK tax year normally makes you UK tax resident. However, spending fewer days does not automatically make you non-resident.
The Statutory Residence Test considers automatic overseas tests, automatic UK tests and, where necessary, connections such as family, accommodation and work. Your residence history can also affect the assessment.
The practical consequence is important: do not plan around “staying below 183 days” without checking the full test.
Arrival Dates and Tax Years Matter
The UK tax year runs from 6 April to 5 April, rather than following the calendar year used by most US individual taxpayers.
Split-year treatment may divide a qualifying year into overseas and UK parts, but it is not automatically available simply because you move midway through the year.
Before moving, record your UK visits, workdays and housing arrangements. Ask an adviser to establish your likely residence position before making decisions that depend on being outside the UK tax system.
The Four-Year Foreign Income and Gains Regime
The Foreign Income and Gains regime, or FIG regime, began on 6 April 2025. It replaced the former remittance basis and allows qualifying residents to claim UK relief on eligible foreign income and gains.
It is not a general four-year tax holiday for everyone arriving in Britain.
Who Qualifies?
Broadly, you must be within your first four UK-resident tax years after at least ten consecutive tax years of non-UK residence.
The window runs for four consecutive tax years. Unused years cannot be saved for later, and people whose UK residence began before April 2025 may have only part of the window remaining.
This makes the residence assessment particularly important: establishing when your first qualifying year begins can affect how much relief remains available.
Which Income Can Qualify?
Eligible categories can include foreign dividends, interest, overseas property income and qualifying foreign capital gains.
Foreign employment earnings do not qualify under the ordinary FIG income relief. Separate Overseas Workday Relief rules may be relevant to eligible employment income. A salary paid from America should therefore not be assumed to qualify merely because the employer or bank account is overseas.
A Claim Has Trade-Offs
FIG relief must be claimed through Self Assessment for the relevant year. Making a claim can mean losing the UK income tax Personal Allowance and Capital Gains Tax annual exempt amount.
The decision should therefore compare the relief gained with the allowances lost and the US consequences.
For an American taxpayer, income relieved from UK tax may still be taxable in the United States. A UK tax saving does not automatically produce the same reduction in your combined tax bill.
UK Income Tax Rates Depend on Where You Live
For 2026–27, the principal income tax rates in England, Wales and Northern Ireland are 20%, 40% and 45%. The standard Personal Allowance is £12,570, although it reduces by £1 for every £2 of adjusted net income above £100,000.
These are progressive rates: moving into a higher band does not mean all your income is taxed at that rate. Savings and dividends also have separate rules.
Scotland Has Different Bands
Scottish income tax applies different bands and rates to wages, pensions and most other taxable income. For 2026–27, those rates range from 19% to 48%.
Savings interest and dividends follow the wider UK rules. An American choosing between Edinburgh and an English city should therefore avoid assuming the income tax calculation is identical.
Foreign Tax Credits Can Reduce Double Taxation
Foreign Tax Credits can reduce US tax where qualifying foreign income tax is paid or accrued on income also taxed by the United States.
That is why UK tax paid on earnings can be important when calculating the US liability. However, the statement that UK rates “typically wipe out US liability” is too sweeping to use as a planning assumption.
Credit eligibility, limitations, income categories and timing all matter. A higher headline UK rate does not guarantee that every US tax charge disappears.
Ask your adviser to calculate the combined result, rather than comparing the countries’ top rates.
Foreign Earned Income Exclusion: Confirmed Limits and Important Restrictions
The maximum Foreign Earned Income Exclusion is:
- $130,000 per qualifying person for tax year 2025.
- $132,900 per qualifying person for tax year 2026.
Eligibility requires meeting the relevant foreign tax-home and residence or physical-presence conditions. Part-year eligibility can reduce the maximum available exclusion.
It Does Not Cover Every Type of Income
The exclusion concerns qualifying foreign earned income, such as wages or income from services.
It does not exclude ordinary investment income, capital gains, pensions or Social Security benefits. Retirees should therefore not treat the exclusion limit as a general tax-free allowance for retirement income.
Coordinate the Exclusion With Foreign Tax Credits
You cannot claim a Foreign Tax Credit for foreign taxes attributable to income excluded under the Foreign Earned Income Exclusion.
The choice needs to be modelled carefully. Claiming the largest available exclusion is not automatically the best outcome for someone paying UK tax.
Get Coordinated Advice Before Financial Decisions
The most useful next step is a review by someone who understands both US and UK individual taxation.
Before the meeting, prepare:
- Your proposed move date and recent UK travel history.
- Employment, self-employment and rental income details.
- Pension and retirement account information.
- Investment holdings and anticipated sales.
- Foreign account balances and ownership details.
- Previous US and UK filings, where applicable.
Ask for a clear assessment of residence, FIG eligibility, reporting obligations and the interaction between credits and exclusions before moving money or selling assets.
