FAQs British Citizens Abroad
1. Does my nationality decide whether I pay UK tax?
No. UK tax is generally based on residence, source of income and the type of income involved. Being British does not automatically make you UK tax resident, and being American does not prevent you from being UK tax resident.
A British citizen living abroad may still have UK tax obligations if they have UK income or UK assets. An American living in the UK may have UK tax obligations because they are UK resident, even though they also remain subject to US tax rules.
---
2. How does the UK decide whether I am tax resident?
The UK uses the Statutory Residence Test. This looks at day count, work pattern, UK home, overseas home, family ties, accommodation ties, work ties and previous UK residence.
Residence is considered separately for each UK tax year. You may be UK resident in one tax year and non-resident in another.
---
3. What is the UK tax year?
The UK tax year runs from 6 April to 5 April.
This is different from the US calendar tax year, which runs from 1 January to 31 December. This difference is one of the main reasons UK and US tax returns often do not match line by line.
---
4. What is split-year treatment?
Split-year treatment can apply when someone arrives in or leaves the UK part-way through a tax year and meets specific conditions.
If split-year treatment applies, the tax year is divided into a UK part and an overseas part. This can limit the UK tax exposure on certain foreign income and gains for the overseas part of the year.
Split-year treatment is not automatic and depends on the facts.
---
5. I moved to the UK during the year. Am I taxed in the UK from the date I arrived?
Possibly, but not always as simply as that.
If you become UK resident part-way through a UK tax year, you may qualify for split-year treatment. If you do not, you may be treated as UK resident for the whole tax year, although treaty rules and foreign tax credit relief may still be relevant.
This is particularly important for Americans moving to the UK because the UK and US tax years do not align.
---
6. I left the UK during the year. Do I stop paying UK tax on the day I leave?
Not necessarily. You may be non-resident from the day after you leave if the conditions for split-year treatment are met. If not, you may remain UK resident for the whole UK tax year.
Even if you become non-resident, you may still have UK tax obligations on UK-source income, such as UK rental income, UK pension income, UK employment duties or UK property gains.
---
7. Do Americans living in the UK need to file a UK tax return?
Often, yes, but it depends on the circumstances.
You may need a UK Self Assessment tax return if you have self-employment income, rental income, foreign income, capital gains, untaxed income, high income child benefit charge issues, partnership income, or other matters that need to be reported to HMRC.
Being paid through PAYE does not always mean a UK tax return is unnecessary.
---
8. I am employed in the UK and taxed through PAYE. Do I still need a UK tax return?
Maybe.
PAYE may cover straightforward UK employment income. However, you may still need a Self Assessment tax return if you have additional income or gains, such as:
* US investment income
* US bank interest
* Rental income
* Self-employment income
* Capital gains
* Foreign pension income
* UK property income
* High income child benefit charge
* Company directorship issues
* Complex residence or treaty claims
---
9. Do I need to report US income on my UK tax return?
If you are UK resident, you may need to report worldwide income and gains to HMRC. This can include US wages, self-employment income, interest, dividends, capital gains, rental income, pensions and other income.
Whether UK tax is ultimately due depends on the income type, tax already paid, treaty provisions and foreign tax credit relief.
---
10. Does the UK tax my US bank interest and dividends?
If you are UK resident, US bank interest and dividends may need to be reported in the UK.
The UK may tax foreign interest and dividends, although allowances, tax rates, foreign withholding tax and foreign tax credit relief may affect the final amount payable.
---
11. Do I need to report US brokerage accounts in the UK?
If you are UK resident, income and gains from US brokerage accounts may need to be reported to HMRC.
This can include dividends, interest, capital gains, fund distributions and realised gains from selling shares or funds. The UK calculation may be different from the US calculation, particularly where exchange rates, fund reporting status or pooled cost basis rules apply.
---
12. Why do my UK and US investment gains look different?
UK and US capital gains calculations are often different.
Differences can arise because of:
* Different tax years
* Different currency conversion rules
* Different cost basis rules
* Different treatment of funds
* Different reporting documents
* US wash sale rules versus UK share matching rules
* Different treatment of reinvested income
* Timing differences
A difference does not automatically mean either calculation is wrong.
---
13. Are US pensions taxable in the UK?
Possibly. US pension income may be taxable in the UK if you are UK resident, but the treatment depends on the type of pension and the UK/US treaty.
This can include 401(k)s, IRAs, Roth IRAs, employer pensions, annuities and other retirement arrangements. The UK treatment can be different from the US treatment, so advice should be taken before making withdrawals.
---
14. Is US Social Security taxable in the UK?
For UK residents, US Social Security benefits may need to be considered under the UK/US tax treaty.
The treaty position can determine whether the income is taxed in the UK, the US, or both with relief. This should be reviewed carefully, especially where the taxpayer has other pension income.
---
15. Do I pay UK tax on US rental income?
If you are UK resident, US rental income may need to be reported to HMRC.
The UK calculation may differ from the US calculation. For example, the UK and US may have different rules for depreciation, mortgage interest, repairs, expenses, exchange rates and losses.
Foreign tax credit relief may be available where US tax has also been paid.
---
16. Can I claim credit in the UK for US tax paid?
In many cases, yes. If income or gains are taxable in both the UK and another country, foreign tax credit relief may reduce the UK tax due.
The relief is not always a simple one-for-one deduction. It depends on the income type, the foreign tax paid, the treaty position and the UK tax due on that same income.
---
17. Will I be taxed twice by the UK and the US?
The UK and US tax treaty and foreign tax credit rules are designed to reduce double taxation, but they do not always remove it completely.
Double taxation can still arise because the UK and US may tax income in different years, apply different rules, or treat the same item differently. This is common with pensions, stock options, ISAs, rental income, business income and capital gains.
---
18. What is the Foreign Income and Gains regime?
From 6 April 2025, the UK introduced a new Foreign Income and Gains regime for certain new UK residents.
Broadly, qualifying new residents may be able to claim relief on certain foreign income and gains for a limited period, provided the conditions are met. This replaced the old remittance basis rules for many individuals.
This area is highly technical and should be reviewed carefully before relying on the relief.
---
19. Is the remittance basis still available?
The old remittance basis rules were changed from 6 April 2025.
For current and future years, the new Foreign Income and Gains regime may be relevant for some qualifying new residents. Older years may still involve remittance basis issues, especially where historic foreign income and gains were brought to the UK.
---
20. I am American and live in Scotland. Are Scottish tax rates different?
Yes. Scotland has different income tax rates and bands for certain types of income, including employment income, pension income and self-employment income.
However, savings income and dividend income are generally taxed under UK-wide rules. This means someone living in Scotland may have a different UK tax result from someone living in England, Wales or Northern Ireland.
---
21. I am British but live abroad. Do I still need to pay UK tax?
Possibly. If you are non-UK resident, you usually do not pay UK tax on foreign income and gains. However, you may still pay UK tax on UK-source income.
This can include UK rental income, UK pension income, UK employment duties, UK self-employment or trade income, and gains from UK property or land.
---
22. I live abroad but rent out a UK property. Do I need a UK tax return?
Usually, yes.
UK rental income remains taxable in the UK even if you live abroad. You may also fall within the Non-resident Landlord Scheme.
If approved by HMRC, you may be able to receive rent without tax being deducted at source, but the rental income still needs to be reported and taxed correctly.
---
23. What is the Non-resident Landlord Scheme?
The Non-resident Landlord Scheme applies where a landlord has a usual place of abode outside the UK and receives UK rental income.
If HMRC approval is not in place, the letting agent or tenant may be required to deduct basic rate tax from the rent and pay it to HMRC.
Approval to receive rent gross does not mean the rent is tax-free. It simply means tax is not deducted before the rent is paid to the landlord.
---
24. I live abroad and sold a UK property. Do I need to report it?
Yes, in many cases.
Non-UK residents must report disposals of UK property or land to HMRC, even where there is no tax to pay or a loss has been made. There are strict reporting deadlines.
This applies to both residential and non-residential UK property and land.
---
25. What is the 60-day UK property reporting deadline?
Where UK residential property is sold and Capital Gains Tax is due, the gain generally needs to be reported and the tax paid within 60 days of completion.
Non-residents have reporting obligations for UK property and land disposals even where there is no tax due. Missing the deadline can result in penalties and interest.
---
26. Do I pay UK tax when I sell non-UK assets while living abroad?
If you are genuinely non-UK resident, you usually do not pay UK tax on gains from non-UK assets.
However, temporary non-residence rules can apply if you leave the UK and then return within a certain period. In that case, some gains or income realised while abroad may become taxable when you return to the UK.
---
27. What are temporary non-residence rules?
Temporary non-residence rules can apply where someone leaves the UK, becomes non-resident, realises certain income or gains while abroad, and then returns to the UK within a specified period.
These rules can bring certain income or gains back into the UK tax net. They are especially important for people planning to leave the UK for only a few years.
---
28. Do I need to tell HMRC when I leave the UK?
Often, yes.
If you leave the UK, you may need to notify HMRC, review your PAYE position, consider whether a tax return is needed, claim any repayment due, and check whether split-year treatment applies.
If you continue to receive UK income after leaving, such as rental income or pension income, you may still need to remain within Self Assessment.
---
29. Do I need to tell HMRC when I return to the UK?
Yes, if your UK tax position changes.
Returning to the UK may make you UK resident again. This can bring foreign income and gains within the UK tax system, subject to any available reliefs.
You may need to register for Self Assessment if you have foreign income, self-employment, rental income, gains or other untaxed income.
---
30. Can I claim the UK Personal Allowance if I live abroad?
Possibly. Some non-residents are eligible for the UK Personal Allowance, but it may need to be claimed.
Eligibility can depend on nationality, residence, treaty provisions and the type of UK income. If you are already filing a UK tax return, the claim may be made through Self Assessment rather than by a separate form.
---
31. What is form SA109?
SA109 is the residence, remittance basis and additional information section of the UK Self Assessment tax return.
It is often needed where residence, non-residence, split-year treatment, treaty residence, remittance basis or Foreign Income and Gains issues are relevant.
HMRC’s own online filing service does not always support all residence pages, so commercial software or a tax adviser may be needed.
---
32. What is form SA106?
SA106 is the foreign income section of the UK Self Assessment tax return.
It is used to report foreign income and, where relevant, claim foreign tax credit relief. This may include foreign interest, dividends, pensions, rental income and other overseas income.
---
33. I am paid by a US employer while living in the UK. Where am I taxed?
This depends on where you are tax resident, where the work is physically performed, the terms of your employment, payroll arrangements, treaty rules and whether social security issues apply.
If you are living and working in the UK, the UK may have taxing rights over employment income relating to UK workdays, even if the employer is based in the US.
This is an area where advice should be taken early, especially for remote workers.
---
34. Can I work remotely from the UK for a foreign employer without UK tax issues?
Not always.
Working remotely from the UK can create UK employment tax, payroll, social security, residence and even corporate tax issues. The position depends on the facts, including the length of stay, duties performed, employer location and whether the individual becomes UK resident.
---
35. Do I need to pay National Insurance if I move to or from the UK?
Possibly.
National Insurance depends on employment status, location of work, social security agreements and whether a certificate of coverage applies. This is separate from income tax and should be reviewed where someone works across borders.
---
36. What if I have income in both the UK and another country?
You may need to report the income in more than one country.
The final tax position depends on residence, source, treaty rules, foreign tax credit relief and timing. The same income may need to appear on both tax returns, but the tax paid in one country may reduce the tax due in the other.
---
37. Why does HMRC ask about foreign income if I already paid tax abroad?
Paying tax abroad does not automatically remove the need to report the income in the UK.
If you are UK resident, HMRC may still require the income to be declared. Relief may then be claimed for foreign tax paid, subject to the relevant rules.
---
38. Can EDA deal with HMRC for me?
Yes, once the correct agent authorisation is in place.
EDA can assist with UK tax returns, residence issues, HMRC correspondence, non-resident landlord matters, foreign income, capital gains, treaty claims and cross-border UK/US tax issues.
---
39. Can EDA make HMRC payments for me?
No. Clients should make tax payments directly to HMRC.
We can advise on the amount, payment reference and method of payment, but we do not handle client tax payments or hold client money.
---
40. What documents should I provide for UK tax advice?
The documents needed depend on your circumstances, but common items include:
* P60s and P45s
* Payslips
* UK and foreign pension statements
* UK and foreign bank interest statements
* Dividend statements
* Investment reports
* Capital gains reports
* Rental income and expense records
* Mortgage interest statements
* Details of foreign tax paid
* Dates of arrival and departure
* Travel day counts
* Details of homes available in the UK and overseas
* Employment contracts
* Self-employment accounts
* Prior UK tax returns
* HMRC notices or letters
* US tax returns, where UK/US interaction is relevant
Providing complete information at the start helps reduce delays and follow-up questions.
