If you live in the UK and have income from abroad, it can be hard to know what HMRC expects – especially if your situation feels a bit messy or complicated. As a Newcastle‑based accountant specialising in international and cross‑border tax, I help clients with overseas income, EU connections and late returns understand their position and get back on track with confidence.
1. Why foreign income matters if you live in the UK
Once you are classed as UK‑resident for tax, the general rule is that your worldwide income can fall within the UK tax net – not just money earned here. That might include:
- Rental income from a property in the EU or elsewhere.
- Salary or self‑employed income from work done overseas.
- Interest from foreign bank accounts.
- Dividends from non‑UK companies.
- Overseas pensions.
Many people only discover this when they receive an unexpected letter from HMRC or realise, at the last minute, that their situation is more complex than a basic tax return allows for. My role is to step in before it becomes a problem – or to help you straighten things out if it already has.
2. Understanding UK tax residence (in plain English)
Tax residence is not just about where you feel at home; it follows a set of rules that look at how many days you spend in the UK, where you work, and where your home and family are. In simple terms:
- Spend most of the year in the UK, or have your main home and work here, and you are often treated as UK‑resident.
- Work mainly overseas, with limited visits back to the UK, and you may be treated as non‑resident for that year.
If you move in or out of the UK during the year, “split‑year” rules can apply, so part of the year is taxed as UK‑resident and part as non‑resident. That is where things can get confusing fast – particularly if you are juggling income and assets in more than one country.
When we work together, I walk you through this gently, using your actual travel pattern and circumstances rather than leaving you to puzzle over technical tests on your own.
3. When foreign income must be reported
If you are UK‑resident, foreign income often needs to be reported on your UK Self Assessment tax return. In practice, that usually means:
- Completing the main tax return and the “foreign” pages (SA106) for overseas income.
- Converting each type of income into pounds using reasonable exchange rates.
- Showing any tax already paid overseas so that double taxation relief can be considered.
This applies even where the figures are relatively small or where you believe “it’s already been taxed abroad”. The key idea is: HMRC normally wants to see the income on your return, then apply the rules to work out what is due in the UK after allowing for any foreign tax.
If you are a non‑domiciled individual using special rules (for example, the remittance basis), or you have a more complex investment or trust structure, the picture can be more involved – but you still need a clear plan so you do not accidentally fall foul of the rules.
4. Common pitfalls I see with EU and overseas income
Clients who come to me with foreign income often run into the same few problems:
- Ignoring “small” income
A bit of interest on a German bank account or a few weeks’ rental from an apartment in Spain might feel minor, but it can still be reportable. - Assuming tax paid abroad is the end of the story
Paying tax in another country does not automatically mean nothing is due in the UK, and it certainly does not remove the need to disclose the income here. - Moving country without updating their tax position
People who relocate to or from the UK mid‑year sometimes carry on as if nothing has changed, when in fact their residence status and reporting obligations have shifted. - Poor records and exchange rates
Missing statements, mixed currencies and inconsistent exchange rates make it harder to complete returns accurately – and harder to answer HMRC questions later.
These issues are especially common for individuals and small businesses with EU connections, cross‑border work, or a combination of UK and overseas income streams.
5. How Friendly Assist Accountancy helps
This is exactly the type of situation I set Friendly Assist Accountancy up to deal with: real‑world, often imperfect scenarios where international or cross‑border tax meets everyday life and business.
When we work together, I can:
- Clarify your UK tax residence status and explain what it means for your foreign income.
- Review all your income sources – UK and overseas – and identify what needs to be reported.
- Prepare or tidy up your Self Assessment returns, including the foreign pages, so that everything is consistent and well‑documented.
- Help you correct past returns where foreign income was missed or reported incorrectly.
- Provide ongoing support if you have continuing foreign income, cross‑border contracts, or international business activity.
My approach is friendly, calm and practical. I know these issues can feel stressful or embarrassing, especially if you are behind with HMRC, so my focus is on solutions rather than blame.
HMRC Targets Undeclared Foreign Income: Why UK Residents with Overseas Earnings Need to Act Now
HMRC has intensified its crackdown on undeclared foreign income for UK tax residents, using enhanced international data sharing to identify discrepancies. In 2024, over 5,600 taxpayers voluntarily disclosed offshore income through HMRC’s Worldwide Disclosure Facility – a 22% increase from the previous year – showing many are acting before receiving HMRC nudge letters.
The Data Hunt: How HMRC Finds Missing Foreign Income
HMRC’s Connect system now automatically cross-references UK Self Assessment returns against:
- Foreign bank data from overseas financial centres
- Rental income records from popular UK-owned property destinations (Spain, France, Greece)
- International tax authority exchanges
When foreign income like overseas pensions, EU rental properties, or international dividends appears missing from SA106 foreign income pages, taxpayers receive “nudge letters” prompting voluntary disclosure – or face formal HMRC investigations.
Penalty Reality: 200% vs Voluntary Disclosure Relief
HMRC guidance confirms offshore penalty rates can reach 200% of tax owed, but voluntary disclosure before enquiry typically attracts much lower penalties. This creates a clear window for UK residents with foreign income to regularise their position through proper SA106 reporting.
