Services
Managing UK tax obligations from overseas requires careful attention to residence rules, income reporting and available reliefs. We prepare tailored tax returns for expatriates, non-residents, landlords and international workers, taking account of their individual circumstances. Our assistance extends to foreign income declarations, property expenses, capital gains calculations, tax refund claims and amendments to earlier returns. We agree a fixed fee in advance and oversee preparation, submission and confirmation of the filing.
We provide comprehensive advice on the UK Statutory Residence Test to help expatriates establish their tax residency status. Our assessment examines travel history, working arrangements and connections with the UK, applying the relevant HMRC tests in the correct order. We also consider split-year treatment and provide a written conclusion explaining your residency position and its tax implications.
We offer comprehensive UK international tax guidance for individuals whose residence, work or financial interests extend across national borders. Our work covers the rules governing UK residence, the possibility of split-year treatment, the timing of gains and the application of double tax agreements. We also assess eligibility for relevant foreign income and gains relief and assist with the documentation and self-assessment submissions needed to support your position before HMRC.
If you have failed to report rental income from a UK property, we can guide you through HMRC’s Let Property Campaign. Our work begins with reviewing your circumstances and establishing the potential tax exposure before notifying HMRC. We then prepare the disclosure within the applicable 90-day period, present the evidence supporting your behaviour assessment, and help arrange settlement, including a time-to-pay agreement where necessary.
We provide comprehensive support to UK taxpayers who need to disclose previously undeclared overseas income, capital gains or financial assets through HMRC’s Worldwide Disclosure Facility. Our service covers the entire process, from reviewing your circumstances and registering with the Digital Disclosure Service to calculating liabilities and submitting your disclosure. We also prepare your case carefully to help minimise penalties and achieve compliance.
Our specialist advisers support UK expatriates, overseas professionals and non-resident landlords who need to report a property disposal to HMRC. We establish the correct taxable gain by comparing the three permitted calculation methods and considering any applicable private residence relief, losses and allowable costs. As the election can have significant financial consequences, we identify the most favourable available basis before filing. We manage the reporting process within the 60-day deadline and confirm the amount and reference for payment.

I can't recommend Emma highly enough to advise you and manage your tax affairs. She helped us deal with our rental property tax. We were not familiar with the process, but Emma explained everything very clearly and professionally through an initial video call, then communicated promptly whether on email or her secure platform, or both, just to confirm we were ok with the next steps. She always seemed available for us. We will use her services again for sure.

Emma has lifted a huge weight from my shoulders . Thank you Emma! Highly recommended.
In the year when I moved from the UK to Spain, with a digital nomad visa, I spent months trying to wade through complex systems to determine my UK tax status. I finally gave in and decided to find help - and I'm so glad I came across GTC and Emma. Within a few emails, Emma had found the best path for me and completed my tax return. She was incredibly prompt at responding to my questions, and her knowledge of these complex systems is excellent. Very fair and clear pricing too.

I was referred to Emma by a colleague, and I genuinely couldn’t be happier with the support she provided.
From start to finish, Emma was exceptionally knowledgeable, clear, and incredibly responsive. Navigating UK tax matters and HMRC processes while relocating overseas is stressful at the best of times, but Emma made the entire process feel manageable. She took the time to review forms in detail, explained next steps clearly, and was always quick to respond whenever questions or complications arose.
When issues came up with HMRC — including incorrect information on their side — Emma gave calm, practical advice and helped me understand exactly how to resolve it. Her experience and confidence were invaluable during what could otherwise have been a very frustrating situation.
I would absolutely recommend Emma and Global Tax Consulting to anyone needing expat tax support. Professional, reliable, and genuinely helpful throughout — I wouldn’t hesitate to work with her again.

This was our first year utilizing Emma McDermott at Global Tax Consulting for our UK returns - and it will not be our last as we believe we have finally (after several years of seeking), found a UK tax preparer that we can trust, and that we can work with indefinitely.
We have a fairly complicated tax situation as we have to file in the UK and USA. We are also exploring potential residency in another country (still TBD).
Emma provided comprehensive advice and guidance in completing our UK returns and also liaised with our USA-based tax accountants to ensure that our returns were filed appropriately in both jurisdictions this year.
Emma was an absolute pleasure to work with on our returns. She is warm and friendly, incredibly responsive, and also endlessly patient when answering our many questions.
Emma is reassuringly knowledgeable on the intricacies of international tax reporting and has that very rare skill of being able to break complex tax regulations into easily digestible `bite-sized’ pieces. This was a much-needed skill when dealing with tax dummies like us.
We hope to be working with Emma for many years to come, and we wholeheartedly recommend her to anyone looking for UK tax preparation services, and/or for consulting services that will de-mystify the intricacies of your specific international tax obligations.

I have just started working with Emma to settle my UK tax return. During the initial 30 minute consultation, Emma helped clear up a lot of confusions in regard to my tax questions between UK and AU.
The tax return process with Emma was easy and efficient with minimal back-and-forth with documents. You are also provided a handy customer portal which I found refreshing, and a very organised way for me to keep track of all the documents and any outstanding items to action. She was also very responsive with any questions I had during the process.
Emma also went above and beyond, helping to provide detailed answers, and reaching out to another expat firm in Australian when my Aus accountants were providing inconsistent advice to the tax treaty.
Highly recommend working with Emma to get things done in the most efficient way possible!

I recently faced a serious issue with HMRC regarding worldwide disclosure. Despite exchanging numerous emails over the past 10 months, we made no progress in resolving the issue. HMRC’s lack of transparency left me frustrated.
Desperate for a solution, I reached out to several tax advisers advertised online. Unfortunately, most of them demanded upfront payments without fully understanding my specific problem.
Then I found Emma McDermott, a tax adviser at Global Tax Consulting. Emma took direct action by contacting HMRC for further clarification. Within a month, she successfully resolved the problems that had plagued me for years.
Emma’s service was exceptional:
• Prompt and Efficient: Everything was handled electronically, streamlining the process and minimizing hassle. The turnaround time was impressively quick.
• Highly Responsive and Professional: Emma maintained a consistently high level of professionalism throughout. Her timely communication made a significant difference.
• Excellent Advice: Emma’s expertise provided valuable insights, ensuring the best possible outcome.

Emma and her team at Global Tax Consulting are excellent. I recommend them wholeheartedly.
As an expat who has recently returned to England, I had been looking for a UK-based accountant for several months, primarily to file my taxes, and also to provide lots of ancillary tax advice. After considerable research, I found Emma and GTC.
Emma is friendly, smart and competent, extremely knowledgeable about the UK tax code and HMRC procedures, and very much on top of things. The GTC website and wizard are well designed – better than others I have encountered – making uploading to the portal easy. Emma returned my emails or messages within hours, with full and complete responses, and provided other support and HMRC communication quickly and efficiently. My taxes were completed within days, and Emma stayed abreast of things to ensure the payment went through properly.
Emma and GTC made filing UK taxes as stress-free as possible. I will certainly use their services again next year.

I moved abroad but had some complicated tax issues to resolve in the UK which I had been putting off. Did a free consultation with Emma who simplified everything for me and undertook the work immediately to get everything resolved.
Emma was professional, knowledgeable, friendly, and very proactive during the whole process. I was bouncing all over the place but Emma was always reaching out to get everything finalised asap so I didn't acrue any penalties. She even reached out to HMRC to resolve an issue with my tax residency which I hadn't considered before the consultation.
Overall 10/10 experience and I would happily recommend Global Tax Consulting to anyone.
