Navigating UK Tax as an Expat
So, you’ve packed your bags, moved to the UK, and now you’re staring at a pile of HMRC forms wondering where to start. Being an expat in the UK comes with its perks—think vibrant cities, rich history, and a cracking cuppa—but the tax system? That can feel like a labyrinth. A good expat tax advisor is your guide through this maze, helping you stay compliant while keeping more of your hard-earned cash. Let’s dive into what you need to know about UK taxes as an expat, with practical tips and the latest 2025/26 tax year details to get you sorted.
Why You Need a Specialist Expat Tax Advisor
Now, you might think, “Can’t I just file my taxes myself?” Sure, you could, but the UK tax system is a beast, especially for expats. Unlike a standard UK resident, you’re juggling residency tests, foreign income, and possibly double taxation agreements (DTAs) with your home country. A specialist expat tax advisor knows the ins and outs of HMRC’s Statutory Residence Test (SRT), which determines if you’re a UK tax resident. Spend 183 days or more in the UK in a tax year? You’re likely a resident, taxed on worldwide income. Fewer days? The SRT’s “ties” (like family, work, or property) might still catch you. A pro can analyse your unique situation—say, if you’re splitting time between London and Dubai—and save you from overpaying.
Where and How to Find the Right Expat Tax Advisor in the UK
So, you’re an expat in the UK, drowning in tax forms and wondering who can help you make sense of it all. Finding the right expat tax advisor is crucial—not just any accountant will do, as your cross-border income and residency status demand specialised expertise. Start by looking for advisors with qualifications like Chartered Tax Adviser (CTA) or ACCA, ideally with a proven track record in expat tax issues. Check professional bodies like the Chartered Institute of Taxation (CIOT) or online directories such as Unbiased.co.uk for vetted experts. Client reviews on platforms like Trustpilot or Google can reveal reliability—look for comments on expat-specific cases, like handling DTAs or the FIG regime.
Now, don’t just pick the first name you see. Contact a few advisors for a free consultation (many, like My Tax Accountant, offer this) to discuss your situation—say, foreign dividends or a UK business. Ask about their experience with cases like yours and their approach to HMRC compliance. A good advisor will explain complex rules simply, perhaps using analogies like comparing tax codes to a recipe you can tweak. Fees matter too—expect £150-£300/hour in 2025, but clarify if they offer fixed packages for Self Assessment or VAT.
The rise of online expat tax advisors is a game-changer, especially if you’re in a remote area or splitting time abroad. Virtual platforms allow document uploads, video consultations, and real-time tax planning, all HMRC-compliant via tools like Xero. For expats juggling international schedules, this flexibility saves time and ensures advice is just a click away, whether you’re in London or Lagos. My Tax Accountant (https://www.mytaxaccountant.co.uk/), for instance, combines online efficiency with expert guidance, making tax season less daunting.
Understanding the UK Tax Year and Personal Allowance
Let’s get the basics down. The UK tax year runs from 6 April to 5 April, a quirky holdover from 1752 when Britain tweaked its calendar. For 2025/26, every UK tax resident gets a personal allowance of £12,570, meaning you don’t pay income tax on earnings up to this amount. Earn over £100,000, though, and this allowance shrinks by £1 for every £2 above that threshold. By £125,140, it’s gone. A tax advisor can help you maximise this allowance, perhaps by timing income or making pension contributions to keep your taxable income below £100,000.
Income Band (2025/26) | Tax Rate | Taxable Income Range |
Personal Allowance | 0% | £0 - £12,570 |
Basic Rate | 20% | £12,571 - £50,270 |
Higher Rate | 40% | £50,271 - £125,140 |
Additional Rate | 45% | Over £125,140 |

The Statutory Residence Test: Are You In or Out?
Right, let’s talk about the SRT, because this is where many expats trip up. The test has three parts: automatic overseas tests (proving non-residency), automatic UK tests (confirming residency), and sufficient ties tests (for grey areas). For example, if you’ve been non-UK resident for the past three tax years and spend fewer than 46 days in the UK in 2025/26, you’re automatically non-resident. But if you’ve got a UK home or work here significantly, you might be resident even with fewer than 183 days. A tax advisor can track your days and ties—down to the midnight rule (a day counts if you’re in the UK at midnight)—to ensure you’re not taxed unnecessarily.
The Statutory Residence Test

Foreign Income and the New FIG Regime
Now, here’s a big change for 2025: the remittance basis is gone, replaced by the Foreign Income and Gains (FIG) regime from 6 April 2025. Previously, non-domiciled expats could avoid UK tax on foreign income unless it was brought into the UK. Now, if you’ve been non-UK resident for 10 years before arriving, you get a four-year tax-free window on foreign income and gains, even if remitted to the UK. After that, you’re taxed on worldwide income. A tax advisor can help you claim FIG relief via your Self Assessment tax return (due 31 January 2028 for 2025/26 claims) and plan remittances strategically, especially with the Temporary Repatriation Facility (TRF) offering a 12% tax rate on pre-2025/26 foreign income brought to the UK until 5 April 2027.
Double Taxation Agreements: Avoiding the Double Whammy
Be careful! If you’re earning income from your home country while living in the UK, you might face tax in both places. Thankfully, the UK has DTAs with over 130 countries, ensuring you don’t pay tax twice on the same income. For instance, if you’re a US expat, the UK-US DTA assigns taxing rights for certain income (like pensions) to your country of residence. A tax advisor can help you complete HMRC’s DT-Individual form to claim relief, ensuring you’re not overtaxed. They’ll also check if foreign taxes paid qualify for the Foreign Tax Credit, reducing your UK bill.
Capital Gains Tax: Watch Your Assets
So, you’ve sold some shares or a property abroad—congrats on the gain, but watch out for Capital Gains Tax (CGT). For 2025/26, the CGT annual exempt amount is £3,000, with rates at 18% (basic rate taxpayers) or 24% (higher/additional rate) for most assets, and 24% for residential property for higher earners. If you’re temporarily non-resident (returning within five years), gains made abroad might still be taxed upon return. A tax advisor can use rebasing (valuing assets at 5 April 2019 for pre-2017 acquisitions) to lower your CGT bill or advise on timing asset sales to leverage FIG relief.
National Insurance: Don’t Skimp on Your Pension
None of us wants to think about pensions when we’re settling into a new country, but National Insurance (NI) contributions matter. For 2025/26, Class 1 NI kicks in at 8% on earnings above £12,570 for employees. If you’ve been abroad and missed NI payments, your State Pension (requiring 35 qualifying years for the full £221.20/week) could take a hit. Expats can pay voluntary Class 2 (£3.45/week for self-employed) or Class 3 (£17.45/week) contributions to fill gaps. A tax advisor can review your NI record on GOV.UK and recommend contributions to secure your pension without overpaying.
Practical Example: Meet Priya
Now consider this: Priya, an Indian expat, moved to Manchester in April 2025 after 12 years in Mumbai. She earns £60,000 from a UK job and £20,000 from Indian investments. Without a tax advisor, she might miss the FIG regime’s four-year exemption on her Indian income, overpaying £4,000 in UK tax. Her advisor files SA106 (Foreign Income) with her Self Assessment, claims FIG relief, and secures a DTA credit for Indian taxes paid, saving her thousands. They also plan her NI contributions to maintain her UK pension eligibility.
Next Steps for Expats
Getting your head around UK taxes as an expat isn’t easy, but a specialist tax advisor makes it manageable. They’ll tailor advice to your residency status, income sources, and long-term goals, ensuring compliance and savings. In the next part, we’ll explore how expat tax advisors help business owners and self-employed expats navigate VAT, Corporation Tax, and more, with real-world strategies to keep your business thriving.

Running a Business as an Expat in the UK
Alright, so you’ve settled into the UK as an expat and decided to take the plunge into entrepreneurship—maybe a tech startup in London or a cosy café in Edinburgh. Running a business is thrilling, but the UK tax system throws in some extra hoops for expat business owners. A specialist expat tax advisor can be your secret weapon, helping you navigate VAT, Corporation Tax, and self-employment rules while keeping your finances in check. Let’s break down the essentials for 2025/26, with practical strategies to keep your business humming and your tax bill in line.
Setting Up Your Business: Sole Trader or Limited Company?
Now, let’s start with the big question: should you go solo as a sole trader or set up a limited company? As a sole trader, you report profits on your Self Assessment tax return, paying Income Tax (20% to 45%, depending on earnings) and Class 2/4 National Insurance (NI). It’s simple but exposes your personal assets to business risks. A limited company, however, is a separate legal entity, liable for Corporation Tax (25% on profits over £50,000 in 2025/26, or 19% for smaller profits with marginal relief). You draw a salary and dividends, which can be tax-efficient but involves more paperwork. A tax advisor can crunch the numbers—say, comparing a £70,000 profit as a sole trader (£19,300 tax/NI) versus a company (£12,500 tax, plus personal tax on salary/dividends)—to find the best structure for your situation.
VAT: To Register or Not to Register?
Here’s where things get tricky. If your business’s taxable turnover exceeds £90,000 (from April 2025), you must register for VAT with HMRC, charging 20% on most sales. But even below this threshold, voluntary registration can make sense—especially if you’re selling to VAT-registered clients who can reclaim the tax. For example, Elena, a Spanish expat running a graphic design firm, voluntarily registered to reclaim VAT on her software subscriptions, saving £2,000 annually. A tax advisor can help you weigh the pros (cash flow benefits) against the cons (extra admin) and choose the right VAT scheme, like the Flat Rate Scheme (simpler accounting, paying a fixed percentage of turnover, e.g., 14.5% for consultants).
VAT Scheme | Best For | Key Features |
Standard Scheme | Businesses with high input VAT | Charge 20% VAT, reclaim input VAT, file quarterly returns |
Flat Rate Scheme | Small businesses with low expenses | Pay a fixed % of turnover (e.g., 14.5%), simpler records, annual turnover <£150k |
Cash Accounting Scheme | Businesses with late-paying clients | Pay VAT only when customers pay you, turnover <£1.35m |
Corporation Tax: Keeping It Lean
So, you’ve gone for a limited company—nice move, but now you’re facing Corporation Tax. For 2025/26, the main rate is 25% for profits over £50,000, with small profits at 19% and marginal relief for profits in between. A tax advisor can maximise reliefs, like the Annual Investment Allowance (AIA), letting you deduct 100% of up to £1m on equipment (think laptops or machinery) from taxable profits. They’ll also ensure you meet filing deadlines—your Corporation Tax return is due 12 months after your accounting period ends, with tax paid within nine months and one day. Miss these, and HMRC’s penalties (starting at £100) sting.
Self-Employment: Managing Your Tax Return
If you’re self-employed, your Self Assessment tax return is your annual showdown with HMRC. For 2025/26, you report income from 6 April 2025 to 5 April 2026, with the return and tax due by 31 January 2027. A tax advisor can help you claim allowable expenses—think travel, office costs, or even a portion of your home broadband if you work from your London flat. They’ll also ensure you’re not overpaying on foreign income, leveraging the Foreign Income and Gains (FIG) regime’s four-year exemption for new residents. For instance, a Canadian expat freelancer earning £40,000 in the UK and £10,000 from Canada could save £2,000 by claiming FIG relief.
Hiring Employees: PAYE and NI Obligations
Now, if your business is growing and you’re hiring, you’ll need to run a Pay As You Earn (PAYE) scheme. This means withholding Income Tax and NI from employees’ salaries and paying employer NI (13.8% on earnings above £9,100 per employee in 2025/26). A tax advisor can set up your PAYE system, ensure compliance with Real Time Information (RTI) reporting to HMRC, and advise on tax-free perks like cycle-to-work schemes to attract talent. They’ll also check if you qualify for the Employment Allowance, slashing up to £5,000 off your employer NI bill if your total NI liability is under £100,000.
Cross-Border Challenges: Trading Internationally
Be careful! If your business trades abroad, you’re wading into complex tax waters. Selling goods to the EU post-Brexit? You might need to register for VAT in the buyer’s country or use the One Stop Shop (OSS) scheme to simplify EU VAT filings. For services, the place of supply rules dictate where VAT applies—sell marketing services to a US client, and it’s often zero-rated. A tax advisor can map out your international tax obligations, negotiate DTAs to avoid double taxation on profits, and handle customs duties if you’re importing/exporting goods. They’ll also ensure your transfer pricing (charges between your UK and foreign entities) complies with HMRC’s rules to avoid hefty fines.
Practical Example: Jamal’s Tech Startup
Let’s talk about Jamal, a UAE expat who launched a tech startup in Bristol in 2025. His company, a limited company, projects £200,000 in profits. Without advice, he’d pay £50,000 in Corporation Tax and miss AIA on £30,000 of new servers. His tax advisor claims AIA, reducing taxable profits to £170,000, saving £7,500 in tax. They also set up a Flat Rate VAT scheme, cutting admin time, and structure his salary (£12,570) and dividends to minimise personal tax. When Jamal hires two developers, the advisor secures the Employment Allowance, saving £3,000 in NI. Total savings? Over £12,000 in year one.
Navigating HMRC Investigations
None of us likes to think about it, but HMRC investigations happen—especially if your business deals with complex international transactions. A tax advisor can prepare you for HMRC’s Compliance Checks, ensuring your records (invoices, bank statements, VAT returns) are watertight. If HMRC queries your FIG relief claim or transfer pricing, your advisor will negotiate on your behalf, potentially saving thousands in penalties. They’ll also advise on Making Tax Digital (MTD), mandatory for VAT-registered businesses since 2019 and expanding to Income Tax Self Assessment for sole traders with income over £50,000 from April 2026.

Case Study: How My Tax Accountant Helped an Expat Thrive in the UK
So, you’ve seen how the UK tax system can twist and turn for expats, whether you’re earning a salary or running a business. But what does it look like when a real expat gets expert help to tackle their tax challenges? Let’s dive into a detailed case study about Sofia, a Brazilian expat who moved to London in 2024 and turned to My Tax Accountant (https://www.mytaxaccountant.co.uk/) to sort out her tax mess. This story shows how a skilled tax advisor can transform confusion into clarity, saving money and stress along the way.
Meet Sofia: The Expat Entrepreneur
Now, picture Sofia, a 34-year-old marketing consultant from São Paulo, who landed in London in April 2024 to launch her freelance business. She had a mix of income: £45,000 from UK clients, £15,000 from Brazilian clients, and £10,000 from a rental property back home. Sofia also owned shares in a Brazilian tech firm, which she sold in 2025 for a £20,000 gain. Excited about her new life, she didn’t realise the UK tax system would hit her with a complex web of Income Tax, Capital Gains Tax (CGT), and foreign income rules. Without guidance, she was on track to overpay thousands and risk HMRC penalties.
The Initial Chaos: Emergency Tax and Missed Reliefs
Let’s be honest—Sofia’s first brush with UK taxes was a nightmare. Her UK clients paid her through PAYE for some projects, but without a proper tax code, she was slapped with an emergency tax rate of 40% on her £45,000 UK income, costing her £3,000 more than necessary. She also hadn’t filed a Self Assessment tax return, missing the 31 January 2025 deadline for her 2023/24 tax year (her partial year in the UK). HMRC sent her a £100 late-filing penalty, and she was clueless about claiming relief on her Brazilian income under the UK-Brazil Double Taxation Agreement (DTA). Her CGT liability on the share sale? Completely off her radar.
Enter My Tax Accountant: The Game-Changer
Right, this is where My Tax Accountant stepped in. Sofia found them online (https://www.mytaxaccountant.co.uk/) after a frantic Google search for “expat tax advisor UK.” She booked a free initial consultation with their CEO, Mr. MAZ, a seasoned tax expert with a knack for untangling expat tax knots. During their first call, MAZ listened to Sofia’s story—her freelance work, foreign income, and share sale—and laid out a clear plan to fix her tax issues and optimise her finances for the 2025/26 tax year.
Step 1: Fixing the Emergency Tax Overpayment
First things first, MAZ tackled Sofia’s emergency tax problem. He reviewed her payslips and confirmed she was overtaxed because HMRC hadn’t assigned her the correct tax code (1257L for the £12,570 personal allowance). MAZ submitted a P85 form to HMRC, proving Sofia’s residency status, and requested a refund of the £3,000 overpaid tax. He also ensured her PAYE code was updated for future payments, saving her from further overtaxation. By July 2025, Sofia had her refund, which she reinvested into her business.
Step 2: Leveraging the FIG Regime for Foreign Income
Now, Sofia’s Brazilian income was a goldmine for tax savings. Under the new Foreign Income and Gains (FIG) regime (effective 6 April 2025), Sofia, as a new UK resident after 10+ years abroad, qualified for a four-year exemption on foreign income and gains. MAZ prepared her SA106 (Foreign Income) form for her 2025/26 Self Assessment, claiming FIG relief on her £15,000 Brazilian client income and £10,000 rental income. This saved her £5,000 in UK Income Tax. He also advised her to keep these funds in a Brazilian bank account until 2027, using the Temporary Repatriation Facility (TRF) to remit them at a reduced 12% tax rate.
Income Source | Amount | Tax Without FIG Relief | Tax With FIG Relief |
UK Freelance Income | £45,000 | £6,500 (20% basic rate) | £6,500 |
Brazilian Client Income | £15,000 | £3,000 (20% basic rate) | £0 |
Brazilian Rental Income | £10,000 | £2,000 (20% basic rate) | £0 |
Total Tax Savings with FIG | £5,000 |

Step 3: Minimising Capital Gains Tax
Sofia’s £20,000 gain from selling her Brazilian shares was another headache. Without advice, she’d face CGT at 20% (as a basic rate taxpayer after expenses), owing £3,400 after the £3,000 annual exempt amount. MAZ applied the FIG regime’s four-year CGT exemption, as the shares were held abroad and sold within Sofia’s first four years in the UK. This wiped out her CGT liability entirely, saving £3,400. He also advised her to reinvest the proceeds into UK assets eligible for Business Asset Disposal Relief, potentially reducing future CGT to 10% if she expands her business.
Step 4: Sorting Out Self Assessment and Penalties
Be careful—missing Self Assessment deadlines can spiral fast. MAZ filed a late 2023/24 return for Sofia, negotiating with HMRC to waive the £100 penalty by proving her genuine confusion as a new expat. For 2025/26, he set up a digital accounting system compatible with Making Tax Digital (MTD), ensuring her income, expenses (like £2,000 in software and travel), and foreign income were accurately reported by 31 January 2027. He also claimed DTA relief for Brazilian taxes paid on her rental income, reducing her UK tax by £1,500.
Step 5: Planning for National Insurance and Growth
None of us wants to skimp on pensions, so MAZ reviewed Sofia’s National Insurance (NI) record. As a self-employed expat, she owed Class 2 NI (£3.45/week, or £179.40/year) to maintain her State Pension eligibility. He recommended voluntary Class 2 contributions for her partial 2023/24 year to avoid gaps, costing just £100 but securing a year toward her 35 needed for the full £221.20/week pension. Looking ahead, MAZ advised Sofia on scaling her business into a limited company in 2026, projecting £2,500 in tax savings by drawing a low salary and dividends.
The Results: Savings and Peace of Mind
By October 2025, Sofia’s tax situation was transformed. My Tax Accountant saved her £12,900: £3,000 from the tax refund, £5,000 from FIG relief, £3,400 from CGT exemption, £1,500 from DTA relief, and £100 from the waived penalty. More importantly, she had a clear financial plan, MTD-compliant records, and confidence to grow her business without HMRC surprises. Sofia now meets MAZ quarterly to review her income and plan for VAT registration as her turnover nears £90,000.
