Can You Run a UK Company While Living Abroad? Country-by-Country Tax Guide

Many founders dream of running a UK company from abroad. But, tax rules often move slower than you do. The big question is: when does HMRC stop taxing your income if you leave the UK?

The answer depends on where you live, work, and how your role is set up.

This guide helps you understand what it takes to run a UK Company Abroad smoothly. We cover non-resident UK tax basics, like residence status and employment income. We also talk about HMRC’s rules for working abroad.

It’s important to know the UK tax year runs from 6 April to 5 April. If your new country uses the calendar year, you might have to track two systems. Split year treatment can help, but you need solid evidence.

We also look at your host country’s rules. Local laws can tax you, even if the UK doesn’t. Before starting, check tax residence tests and permanent establishment risk. Also, see if local payroll or social security registration is needed. Getting these right early can protect your company’s profits and your personal finances.

Who this guide is for: directors, shareholders and digital nomads running a UK company overseas

If you’ve left the UK but still run your company, this guide is for you. It’s perfect for a non-UK resident director who manages the business from abroad. They sign contracts, approve spending, and make big decisions.

It also helps UK shareholders living abroad who take dividends. And for digital nomads with a UK company, it answers key questions. Where are you taxed, and what do you need to file?

When you move abroad, three things change. Small details are crucial. We focus on what you can check and record from day one.

Common set-ups: UK limited company with a non-UK resident director

A UK limited company can keep trading even when the founder moves. Often, a UK entity has a non-UK director who manages it remotely. Sometimes, there’s a UK-based co-director too.

Another common setup is a UK shareholder abroad who controls the company but isn’t on payroll. They receive profit distributions. The tax situation can change as your role shifts.

What changes when you leave: tax residence, work location and reporting

First, your HMRC residence status might change. The Statutory Residence Test looks at day counts and UK ties. This affects whether you’re treated as UK resident in a tax year.

Second, where you work matters. For UK employers, it’s where you do the work, not where the company is. This is important for overseas work.

Third, the paperwork can change. PAYE might still apply for some employees. But for others, UK tax reporting overseas means tracking travel days and work logs. You might need to file Self Assessment for untaxed income.

Key warning: company tax rules and personal tax rules do not always align

It’s easy to think that being non-resident means no UK tax. But that’s not true. Company tax rules can stay in the UK, while your personal tax follows your HMRC status and where you live.

This means a UK shareholder abroad might face different rules for dividends. Directors on salary face different rules for workdays. The same business can be in the UK, but your personal tax depends on where you work and make decisions.

UK Company Abroad: what “running” a UK company from another country really means

Living abroad and managing a UK company can be complex. It’s easy to confuse decision-making, daily tasks, and where sales happen. Understanding these areas helps spot risks early and keeps records accurate.

For directors not living in the UK, it’s crucial to separate these aspects. Where you work isn’t always where the company is managed. And neither is where customers experience the service.

Where management decisions are made and why it matters

Tax authorities focus on where decisions are made. They look at who gives the final direction. This is key for managing a company abroad, even with video calls.

Another country might look at where the company is effectively managed. This can differ from the UK’s view. If decisions are made abroad, it can change how the company is seen locally.

Who approves budgets, contracts, and funding?
Where are board decisions prepared, debated, and recorded?
Do minutes match what really happened in practice?

Where the work is physically performed vs where the company is incorporated

There’s a simple question about where work is done. For personal tax, HMRC looks at where duties are performed, not where you’re paid or the company is registered.

This difference is important for directors who work abroad. You might do client work daily while strategic decisions are made in the UK. Both can be true and need to be documented well.

Why banking, invoicing and customer location can change risk

Even with good governance, commercial signals can still pose risks. Local bank accounts and invoicing patterns can make a business seem local, even if it’s managed from the UK.

Customer location also matters. If most sales are in one market, that market might see the business as theirs. We look at banking, invoicing, and customer data alongside governance and management to assess risk.

UK tax residence basics for founders living abroad (Statutory Residence Test and split year)

When we help founders expand abroad, we start with tax residence. This is because it affects what HMRC can tax. The Statutory Residence Test decides if you’re taxed on worldwide income or mainly on UK income. This is key when you want to be seen as a UK non-resident.

Timing is as important as location. UK tax year dates are from 6 April to 5 April. This can clash with other countries’ tax years. Keeping track of days, flights, and work patterns is crucial to avoid record-keeping headaches.

The 183 days UK rule is well-known, but it’s not the only factor. The Statutory Residence Test also looks at your home, time spent there, and UK ties. Even a regular habit, like frequent meetings in the UK, can change your status.

Day counts, including 183 days UK, based on midnights spent in the UK.
Home patterns, such as keeping a place available to live in the UK.
Connections assessed under the UK ties test, including work and family links.

If you leave part-way through the year, split year treatment may apply. This splits the year into two parts. Done right, it can help you be seen as a non-resident for the overseas part. But, you still need to keep records for the UK tax year dates and your travel history.

One common route is full-time work overseas. HMRC looks for a consistent work pattern and limited UK duties. Keeping UK days low, and managing them well around departure and return, is key. A stable pattern across UK tax year dates can reduce uncertainty. But, a stop-start approach might raise questions and lead to re-checks under the Statutory Residence Test.

How HMRC taxes salary when you work abroad for a UK employer or your own UK company

When founders move abroad, the salary talk often focuses on where the work is done. HMRC looks beyond where the company is registered or the bank account is. They care about where the work is actually done.

Employment income sourcing: where duties are physically exercised (s27 ITEPA 2003)

s27 ITEPA 2003 says salary follows where you work, not where the company is. This means your salary is based on where you do your job, not the company’s location.

This is important for those working abroad for a UK employer or their own UK company. If you work in Portugal one day and London the next, HMRC will count each day separately.

Non-resident position: UK tax limited to UK workdays

For many, UK tax only applies to days worked in the UK when you’re not resident. This is the main idea behind non-resident salary tax. Only UK workdays are usually taxed.

Even short UK trips can lead to taxable income, even if most work is done elsewhere. Many directors think working for a UK company means all salary is taxed in the UK.

Record-keeping you’ll need: travel evidence, work calendars and day counts

To prove your split, keep a routine of travel day evidence as you go. HMRC wants clear evidence of your work and travel dates.

Travel evidence like flight confirmations, booking emails, and passport stamps.
A work calendar showing where you worked each day, including UK and overseas days.
Meeting notes and system logs that show where you worked, like diary entries and VPN records.

Keeping records weekly, not just at year end, is best. A clear set of records makes explaining your work abroad easier if HMRC asks later.

PAYE, P85 and the NT tax code: stopping UK payroll withholding after departure

When you move abroad, PAYE can still take money out of your pay, even if you’re not in the UK. This can lead to tax being taken when it shouldn’t be. The goal is to stop PAYE after leaving the UK if you’re not resident and working overseas.

Using the P85 form to notify HMRC you have left the UK

Starting with an HMRC departure notification is the best way. This needs dates and proof. You’ll need to send the P85 form with your leaving date, UK income, and where you’ll live next.

It’s also wise to keep a detailed record of your travel and work. HMRC might check where you worked. If they agree with you, it can help avoid too much tax being taken.

NT (No Tax) code and when salary can be paid gross

If HMRC says you’re not resident for UK tax, they might give you an NT tax code. This lets your UK employer pay you without tax, if you work abroad and your job is consistent with not being resident.

This is crucial for owner-directors. Payroll systems usually take tax out unless told not to. An NT tax code can make sure PAYE matches HMRC’s expectations for overseas work.

The “incognito” option: keep PAYE running and reconcile through Self Assessment

Some people keep PAYE running, even if they work abroad. This is easier if your travel is complex or you have UK workdays. You can then claim back PAYE through Self Assessment, using your work days and income to work out your tax.

Choose this if you’re not sure and want to sort it out later.
You’ll need to show clearly that you worked abroad, with calendars and travel proof.
Think about your money flow, as refunds can take a while.

Self Assessment triggers for non-residents and overseas company owners

When you move abroad, you might think UK tax admin stops with PAYE. But, Self Assessment non-resident filings are still needed for founders, directors, and landlords with UK income. We help you understand what HMRC expects and what evidence supports your position.

When Self Assessment is common: self-employment, rental income and untaxed income

Many employees pay UK tax through PAYE, so they don’t file every year. But, Self Assessment is needed for self-employment profits, extra tax on dividends, or other untaxed income.

If you get UK rental income abroad, HMRC expects property pages with your main return. For most, that means SA100, SA105, and SA109 are key: SA100 is the main return, SA105 covers UK property, and SA109 deals with residence status and split-year details.

SA100: main UK tax return for reporting income and claiming reliefs.
SA105: UK property pages for rents, allowable costs, and finance restrictions.
SA109: residence, split-year treatment, and non-resident disclosures.

PAYE documents are still important for your working papers. A P60 is useful if you were employed on 5 April. A P45 supports the date you left a UK job and what tax was deducted.

Key deadlines to plan around: registration and online filing/payment dates

Deadlines can feel tighter when you’re in a new time zone and waiting on bank or agent access. We plan early because a UK tax return overseas may involve third-party data, such as letting agent statements, interest certificates, and payroll records.

If HMRC needs you to file, you may also need to register before you can submit online. This lead time is crucial, as SA100 SA105 SA109 pages are needed to support a Self Assessment non-resident position.

Payments on account and cash-flow planning

Payments on account can surprise people the first year they enter Self Assessment, as they bring forward tax for the next year. If you have uneven income, such as UK rental income abroad with void periods or large repairs, cash-flow planning becomes part of the tax work.

We also check whether payments on account are actually due, and whether a sensible reduction is available. The aim is to avoid overpaying tax too early while keeping HMRC comfortable with the numbers.

Making Tax Digital for Income Tax from 6 April 2026: what it may change for landlords and sole traders

Making Tax Digital 2026 is set to change the rhythm of reporting for many sole traders and landlords. Instead of one annual submission, digital record-keeping and more frequent updates may become the norm. This can be a shift if you manage finances across borders.

For anyone with UK rental income abroad or self-employment income, it is worth reviewing your bookkeeping tools and bank feeds now. If you already file a UK tax return overseas, aligning records early can make the transition to Making Tax Digital 2026 smoother and reduce errors around dates, currency, and allowable expenses.

Bonuses, equity and deferred pay after you move: why timing is not decisive

When founders leave the UK, they often face a common issue. A payment might come after they’ve gone, making it seem like it’s not in the UK. But, the real test isn’t just when the money is paid.

It’s about when the work was done. HMRC looks at the time the value was built up. This includes the work period, vesting window, and any performance or service conditions.

How HMRC can source bonus and share awards to the period earned/vested

HMRC can split a bonus or share award over time. This rule applies even if you’re not in the UK when the money comes in or shares are given out.

For employers and owner-directors, this rule is useful. It helps in mapping awards to UK and overseas workdays.

Check the award letter for the “performance period” and any deferral rules.
Confirm the vesting date, and whether vesting depends on service.
Keep a workday record so UK and overseas duties can be separated.

Example scenario: bonus paid after departure but earned during UK residence

Imagine a bonus based on a UK trading year, paid months later after you’ve moved. HMRC might still treat part of it as UK tax, because it was earned while you were here.

The split often follows UK workdays in the relevant period. If your role changed mid-year, the calculation might need more detail than just counting days.

Example scenario: equity spanning UK resident and non-resident periods

Equity can create longer timelines, making it easier to get caught out. With equity vesting non-resident, the question is how much of the vesting period was in the UK, where the award depends on staying employed.

If you leave during a tax year, split period equity taxation might apply. We usually look at the grant date, vesting schedule, and any UK workdays in the vesting window to see what’s still in UK scope.

Personal allowance abroad: when you can still use the 0% band as a non-resident

Going abroad doesn’t mean you lose the UK’s tax-free allowance. Many founders wonder if they can still get some income taxed at 0%.

This is important because the 0% band can lower your UK tax on income from the UK. This includes salary, director’s fees, and other UK income.

If you qualify, HMRC can apply the allowance through Self Assessment or payroll. But, it’s important to note that being a resident and being eligible for the allowance are different.

UK and EEA citizens might still get the allowance, even after moving.
Others might qualify through a double taxation agreement. But, the rules vary by treaty.

We look closely at what HMRC needs to see. This includes your nationality, the type of UK income you get, and how your overseas tax affects your UK reporting. Are you getting PAYE income, dividends, or a mix throughout the year?

Getting it right early can prevent overpaid tax and messy year-end fixes. It also helps keep your records clean if you’re asked about claiming the personal allowance while abroad.

Country-by-country tax guide: what to check in your new country before you run a UK company there

Before starting a UK company abroad, we do detailed tax checks. We aim to find issues early, when changes are still easy to make. This includes personal and company taxes, and the paperwork for both.

Some tax rules seem simple but can catch you out. Moving, getting a new lease, or opening a local bank account can change your tax situation. So, we start with the basics and build up from there.

Local tax residence tests: days, home and centre of vital interests

First, we look at host country tax residence. Countries often check how many days you spend there, if you have a local home, and where your life is centred. The centre of vital interests test can be key when things are not clear-cut.

We make your travel and living situation easy to understand. Then, we compare it to the local rules on residence. This helps avoid unexpected taxes on your worldwide income.

Permanent establishment risk: when the host country may tax company profits

Next, we examine permanent establishment risk. If you sign deals or run key operations abroad, the host country might tax your company profits. This can affect your UK company’s earnings.

We also look at signs of a permanent establishment: office space, staff, and where big decisions are made. Even short periods can count if the activity is regular and business-like. Keeping good records is crucial here.

Director’s fees, salary, dividends and capital gains: which country taxes what

Different types of income are taxed differently. Director’s fees, for example, might be taxed under specific rules and not like salary. Dividends can face withholding tax, and capital gains rules vary by asset and where you live.

We match what the UK taxes with what the new country does. We also look at where you can claim relief. This includes how to report if you earn UK payments while abroad. Clear categorisation helps avoid filing mistakes.

Local payroll, social security and mandatory registrations

If you pay yourself a salary, dealing with overseas payroll can be tough. Some countries need you to register locally, report monthly, and file employer details, even if your company is in the UK. Penalties often start with late registration, not late tax.

We also check social security abroad. This includes if you can stay in UK National Insurance or if local contributions are needed for employer and employee. Getting this right early helps with clean payroll, accounts, and fewer disputes later.

Confirm host country tax residence triggers and treaty tie-breaks
Assess permanent establishment risk from daily work and decision-making
Separate salary, dividends, gains, and director’s fees taxation in your plan
List registrations for overseas payroll compliance and social security abroad

US-specific section: if you are a US citizen or Green Card holder running a UK company from the UK or abroad

Managing a US citizen UK company can be tricky. It’s like two different systems trying to talk to each other. This is true for Green Card holder UK limited companies, no matter where you are in the world.

Mel Whitney, EA, updated us on 31 March 2026. UK tax rules can change what HMRC taxes. But, they don’t stop you from filing US taxes.

US citizenship-based taxation: Form 1040 on worldwide income even if tax due is $0

Most Americans still file Form 1040 every year, even if they owe no US tax. This includes income from salary, dividends, and director’s fees. It also includes some UK savings interest related to your role.

The biggest challenge is not the maths. It’s gathering accurate figures from two tax years, two currencies, and different pay dates.

Double tax relief tools: Foreign Tax Credit, Foreign Earned Income Exclusion and treaty positions

Choosing the right tool for your income type is key for double tax relief. The Foreign Tax Credit UK is often used when you’ve already paid UK tax. You then use it to offset US tax on the same income.

FEIE UK might be right for you if you have earned income and meet certain tests. But, it’s not a solution for all. The US–UK tax treaty can also play a role, depending on the income type and sourcing rules.

Match each income stream to the correct relief route before you file.
Track which amounts are taxed in the UK first versus taxed in the US first.
Keep support for exchange rates and payment dates, as these drive the final numbers.

Filing calendars do not align: US calendar year vs UK 6 April–5 April

The US follows a calendar year, while the UK’s tax year is from 6 April to 5 April. This mismatch can cause timing issues, like when dividends are declared near year end.

We plan early for reconciliation. This is because “same year” doesn’t always mean the same period in both countries.

Key US deadlines for 2025 tax year filed in 2026: 15 April 2026, 15 June 2026 (automatic abroad), 15 October 2026 (extension)

US deadlines can surprise founders used to UK dates. For the 2025 US tax year filed in 2026, key dates are 15 April 2026, 15 June 2026 if abroad, and 15 October 2026 with an extension.

Even with extra time, interest can apply if tax is late. So, we separate “filing” from “paying” in your planning.

Common extra reporting: FBAR (FinCEN 114) and Form 8938

Running a UK company can mean extra reporting. FBAR FinCEN 114 is about foreign financial accounts, including UK bank accounts where you have authority, not just personal savings.

Form 8938 FATCA is another disclosure needed, even if you’ve done an FBAR. It’s important to map accounts, roles, and thresholds early for accurate and consistent reporting.

Self-employment tax and social contributions when you live abroad

When we help founders move overseas, we separate income tax from social contributions straight away. It’s easy to think one return covers everything. But, payroll-style charges often have their own lane. This matters a lot if you keep trading through a UK company, freelance on the side, or do both.

US self-employment tax basics

For US citizens and US tax residents, US self-employment tax abroad can still apply even when the work is done outside the States. The core test is simple: if net earnings are at least $400, the charge can kick in. It is calculated and reported through Schedule SE, based on net profit rather than turnover.

Location alone does not switch it off. If you are self-employed while living in the UK, you may still face US Social Security and Medicare rules alongside local obligations.

Why the Foreign Earned Income Exclusion does not remove it

Many people expect the Foreign Earned Income Exclusion to wipe the slate clean. It can reduce US income tax on eligible earnings, but FEIE self-employment tax is a different issue. In other words, FEIE self-employment tax can remain due even if your income tax bill drops to zero.

We often see this missed when someone moves mid-year and focuses only on the headline FEIE amount. The paperwork still needs to match the reality of how you earned the income.

Totalisation agreements and proof of the right system

A totalisation agreement can help you avoid paying into two social security systems on the same earnings. The aim is to keep you in one country’s scheme at a time, depending on your status and where the work is anchored.

A certificate of coverage is the document that backs up which system you should pay into.
It can be requested to support a US or UK position, specially when contributions are questioned by an employer, accountant, or tax authority.

UK National Insurance: what changes by status

On the UK side, National Insurance is separate from income tax, and the class depends on how you are paid. UK National Insurance Class 1 is typically linked to employment through payroll, even if the employer is your own company. For self-employed profits, the usual route is Class 2 Class 4 NI, calculated through Self Assessment rules.

Where it gets tricky is when you mix roles, such as taking a director salary and also billing as a sole trader. The labels affect what you pay, what you file, and which country may claim priority under the totalisation agreement.

Investment, pension and property traps for overseas owners of UK companies

Founders of UK companies abroad often face surprises that aren’t about Corporation Tax. These surprises usually come from personal investments, pension paperwork, and how countries define gains. A small admin choice can lead to years of reporting or unexpected tax charges.

ISAs: tax-free in the UK does not automatically mean tax-free elsewhere (including the US)

An ISA can be simple in the UK, but ISA US tax can be a shock for US citizens and Green Card holders. The UK wrapper isn’t always recognised, so income and gains can still be taxed in the US.

Also, many popular funds in ISAs can be treated as PFIC UK ETFs for US tax purposes. This can change how gains are taxed and how much reporting is needed.

Check what you hold, not just where you hold it.
Track dividends, distributions, and fund switches with clean records.

UK pensions: treaty-sensitive treatment and reporting nuance

UK pensions often travel better than ISAs, but the details matter. The tax result can depend on plan type, contribution timing, and what your host country treats as “pension income”.

Even with tax reductions, reporting can still apply. Missing forms can cost more than the tax itself.

Capital gains on disposal: UK property CGT rates for gains from 6 April 2025 (18%/24%) and cross-border timing differences

Property and shares can create a double-layer problem: rate changes and timing mismatches. The UK’s residential property CGT rate will change to 18% or 24% from 6 April 2025. This can affect the after-tax result on a sale.

The harder part is cross-border capital gains timing. The UK, the US, and many EU systems can disagree on taxable dates, cost basis, and currency conversion. So, the same disposal can land in different tax years.

Confirm the disposal date each country uses (exchange vs completion can matter).
Keep evidence for valuations, improvements, and selling costs.
Plan for cash flow if two tax bills arrive months apart.

Inheritance tax exposure: UK rules vs foreign estate tax systems

Estate planning can also be tricky. UK inheritance tax can still apply even if you live abroad, based on UK connections and asset structure.

Your new country may also have its own estate or succession rules. These can be based on citizenship, domicile, or asset location. This overlap can lead to delays, extra filings, and costs.
