Living in the UK as an American: The UK Hub for Expats
Living in the UK as an American comes down to three things: getting a visa that lets you live there, adjusting to daily life from healthcare to banking, and continuing to file U.S. taxes each year even though you now pay UK tax. It is very doable, and most Americans end up owing the IRS nothing because the UK taxes they already pay are credited against their U.S. bill.
This page is your UK hub. Whether you are planning the move, newly arrived, or years into life abroad, it connects every stage of the journey and links you to a dedicated Greenback guide for each one, from the visa that gets you there, to daily life once you land, to staying compliant with both HMRC and the IRS.
What this hub covers:
- Getting there: the visa routes Americans use and how to plan the move.
- Settling in: cost of living, housing, healthcare, banking, schools, and work.
- Your U.S. taxes: what you still owe the IRS and how to avoid being taxed twice.
- Every UK topic in one place: a dedicated guide for each stage, cross-referenced here.
The UK at a Glance for Americans
| Fact | What to know |
|---|---|
| Currency | Pound sterling (GBP) |
| UK tax year | 6 April to 5 April, not the calendar year |
| Healthcare | The NHS, accessed through the Immigration Health Surcharge |
| Short visits | An Electronic Travel Authorization (ETA) is required |
| Settlement | Indefinite Leave to Remain is usually available after five years |
| U.S. taxes | Still filed every year on your worldwide income |
Before You Move to the UK
Almost every American needs permission to live in the UK, and the route you choose shapes how long you can stay, whether you can work, and when your family can join you. Getting this stage right is the foundation for a smooth move, and it pays to make a few tax decisions before you leave while you are still a U.S. resident.
Choosing Your Visa Route
Start with the overview, then read the guide for your situation:
- UK visa options for Americans: the full menu of routes and how to match one to your plans.
- Skilled Worker visa: the main work route, requiring a licensed sponsor and a salary above the threshold.
- Family and spouse visa: for moving with or to a partner, with its own income requirements.
- Ancestry visa: for Commonwealth citizens with a UK-born grandparent (a U.S. passport alone does not qualify).
- Electronic Travel Authorization: the entry permit is now required even for short visits.
Most of these routes lead to settlement, known as Indefinite Leave to Remain, after five years of continuous residence, and to British citizenship after that.
Planning the Move
Once your route is clear, the logistics begin, and the tax side is the part most people overlook:
- Moving to the UK from the USA: the step-by-step guide to shipping, timing, and setup.
- Pre-move tax checklist: eight things to handle while you are still a U.S. resident.

Settling Into Life in the UK
The practical side of expat life starts the moment you land, and the everyday systems work differently enough from home to catch newcomers off guard. Costs vary sharply by region, banking can be slower than expected, and healthcare works on a completely different model. These guides cover what to expect.
Cost of Living and Where to Live
Location drives nearly everything about your budget, so start here:
- Cost of living in the UK: how prices compare to the U.S., with housing the biggest swing and NHS care and car-free living offsetting it.
- Cheapest and best places to live: London weighed against the more affordable cities and towns where expats settle.
Everyday Essentials
The systems you will use every week take a little getting used to:
- Working in the UK: your right to work and how the job market runs.
- Opening a UK bank account is often slower for Americans because FATCA rules make some banks cautious.
- Healthcare and the NHS: most visa holders pay the Immigration Health Surcharge, currently £1,035 per adult per year, then use the NHS like residents.
- Schools in the UK: free state schools, private schools (now with 20% VAT on fees), and American international schools.
- Retiring in the UK: what a UK retirement looks like for an American.
Your U.S. Taxes While Living in the UK
Here is the part that surprises Americans most: you keep filing U.S. taxes for life because the U.S. taxes based on citizenship, not residence. The reassuring news is that the two countries have tools that prevent the same income from being taxed twice, so most Americans living in the UK owe the IRS little or nothing. The trick is knowing which rules apply to your situation, and this is where the UK cluster goes deep.
Start with these three:
- U.S. expat taxes in the UK: the main guide to filing your U.S. return from the UK.
- How the UK tax system works: the HMRC side, from the tax year to bands and PAYE.
- UK vs. U.S. taxes: a side-by-side of the two systems.
Filing and Avoiding Double Tax
Every American in the UK files a U.S. return, but reliefs usually bring the bill to zero. The Foreign Tax Credit and the Foreign Earned Income Exclusion do the heavy lifting, backed by two agreements and the UK’s own filing rules:
- U.S.-UK tax treaty: decides which country taxes each type of income.
- U.S.-UK Totalization Agreement: keeps you from paying social taxes to both countries.
- UK Self Assessment: The UK requires some people to file a return, with the system now moving to Making Tax Digital.
- U.S.-UK dual citizen taxes: the extra wrinkles if you hold both passports.
Retirement and Pensions
UK pensions are valuable, but the IRS treats them differently from HMRC, so they need careful handling:
- UK pensions and SIPPs: how contributions and growth are reported to the IRS.
- UK State Pension: how it is taxed and how to qualify.
- QROPS and pension transfers: why an offshore transfer can create U.S. tax problems.
Property, Savings, and Investments
Owning or investing in the UK means two sets of rules apply at once:
- Buying property in the UK: the process, taxes, and financing.
- Capital gains tax on property: what you owe when you sell.
- Rental income for landlords: UK and U.S. rules if you let out a home.
- UK inheritance tax: how it works alongside the U.S. estate tax.
- The ISA trap: a UK tax-free account that the IRS treats as taxable in full.
Business and Self-Employment
Working for yourself adds U.S. forms on top of the UK ones:
- Self-employed in the UK: income tax, National Insurance, and your U.S. obligations.
- Owning a UK limited company: how U.S. rules on foreign corporations, including Form 5471, apply.
Family
- UK Child Benefit and the U.S. Child Tax Credit: how to claim both without one canceling the other, plus the High Income Child Benefit Charge.
A Typical First Year for an American in the UK
Most Americans follow a similar path, and seeing it laid out makes the whole move feel less daunting. First comes the visa and the move itself, usually the busiest stretch, followed by the pre-move tax steps that are easiest to handle before you leave. Once you arrive, you open a bank account, register with a GP for healthcare, and start getting a feel for daily costs and your new neighborhood.
For most of that first year, nothing about tax feels urgent, because your UK employer settles your UK tax automatically through PAYE. The part that catches many people out arrives the following spring, with their first U.S. return as a UK resident. That is when the reliefs matter most, and when having both returns prepared together turns a complicated year into a manageable one. Getting the first filing right also sets the pattern for every year after it, which is why many Americans bring in a cross-border preparer from year one rather than untangling it later.
How Greenback Helps Americans in the UK
Greenback is an American company founded by U.S. expats, and the UK is one of the places where we work the most. Living across two tax systems is manageable, but it rarely stays simple: your UK income feeds your U.S. return, your UK pension and accounts trigger U.S. reporting, and the reliefs that save you money only work when both returns are prepared together and in the right order.
What sets the UK service apart is that we handle both sides on one account:
- A UK Chartered Accountant and a U.S. accountant work on your file together, so the numbers line up across HMRC and the IRS.
- Both returns in one place: your UK tax services cover your UK Self Assessment alongside your U.S. federal return, FBAR, and FATCA reporting.
- A path back if you are behind: the Streamlined Filing Procedures help non-willful late filers get compliant, usually without penalties, and most owe little or nothing once the Foreign Tax Credit is applied.
- A no-pressure start: a short consultation is the easiest way to see what your situation really requires.

Frequently Asked Questions
You have to file a U.S. return every year on your worldwide income, but most Americans in the UK owe the IRS nothing. Because UK tax rates are generally higher than U.S. rates, the Foreign Tax Credit usually cancels out your U.S. bill, though you still report your income and any qualifying accounts.
Yes. For any stay longer than a standard visit, you need a visa, and the right one depends on your work, family, or ancestry. Short visits also require an Electronic Travel Authorization. Our UK visa guides cover each route and who qualifies for it.
Most work and family routes lead to Indefinite Leave to Remain after five continuous years in the UK, and to British citizenship after that. Time on some visas counts toward settlement, while time on others does not, so it is worth checking your specific route.
It depends heavily on where you live, with London far pricier than most of the country. Housing is the biggest difference from many U.S. cities, while free NHS care and, in many areas, the lack of a need for a car can offset it. Our cost-of-living guide breaks down the comparison.
Yes. Filing and owing are separate. You file a U.S. return every year to report your income and claim the reliefs that reduce the bill, and you may also file account reports such as the FBAR, even in years when your final U.S. tax is zero.
Almost never. The Foreign Tax Credit and the U.S.-UK tax treaty exist to prevent double taxation, and because UK tax is generally higher, the credit usually erases your U.S. tax on the same income entirely.
Usually yes, but some U.S. accounts and UK products interact badly with the other country’s rules, and UK tax-free accounts like ISAs are taxable to the IRS. It is worth reviewing your accounts with a cross-border tax preparer before and after the move.
