Services
We take responsibility for preparing accurate UK tax returns for clients living abroad or managing income across several countries. After reviewing your circumstances, we complete the relevant Self Assessment pages and assess claims for exemptions, allowances, expenses and relief against overseas tax. We also assist with rental income reporting, PAYE refunds and overdue returns where required. Our secure online process keeps documentation organised, while direct HMRC filing helps ensure your obligations are addressed on time.
We specialise in assessing UK tax residency for expatriates and internationally mobile individuals. Your assessment brings together travel history, day counts, work patterns, available homes and connections with the UK to establish which statutory rules determine your status. Where appropriate, we also review the conditions for split-year treatment. Our written advice explains the outcome and provides the supporting rationale for use with HMRC, employers or banks.
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.
Our approach to the Let Property Campaign combines detailed preparation with careful management of your HMRC disclosure. We reconstruct rental profits using surviving documentation, including bank statements, letting agent summaries and relevant expenses, before calculating tax, interest and penalties. We also explain and evidence the circumstances behind the omission, helping establish the appropriate penalty position before the disclosure and settlement are completed.
Our service is designed for UK taxpayers who need to regularise their tax affairs following the omission of overseas income, gains or assets. We manage the Worldwide Disclosure Facility process by identifying the information HMRC requires, registering the intention to disclose and preparing year-by-year calculations in sterling. The completed submission explains the relevant circumstances, claims applicable foreign tax relief and sets out the proposed settlement, including tax, interest and penalties.
We help overseas property owners fulfil their UK Capital Gains Tax obligations without unnecessary complications. Following completion, we review the relevant documents, establish the property's tax base and calculate the gain using all three permitted approaches. Available reliefs, allowances and allowable expenses are taken into account before we elect the most favourable basis. Our service covers preparation and submission of the non-resident return, together with the tax payment information required within 60 days.

Emma provided exceptional advice on my international tax position as a UK expat. She navigated complex areas including UK tax law and international treaties with clarity and precision. Her analysis was thorough, methodical and gave me exactly the strategic clarity I needed to make important decisions. Highly recommend GTC for anyone navigating expat tax planning.

Having left the UK at the beginning of the year I needed a professional expat tax consultancy company to assist me with my tax affairs. I cannot recommend Emma at GTC enough, her knowledge of the expat tax world is exceptional and her efficiency and speed of dealing with matters is unmatched. I could not be any happier with the service I have received and would highly recommend GTC and Emma to anyone needing similar services. David

Emma was fantastic from the moment I contacted her: prompt responses to emails, knowledgeable, and professional. I made first contact 9 days ago, and I have a refund from HMRC hitting my account tomorrow!
What makes this even more impressive is that I was advised by two separate accountants that I was still liable for UK tax - despite that fact I am based overseas - but I wasn't convinced that they had understood my situation properly. If you're a remote worker or digital nomad, don't waste your time communicating with anyone else apart from Global Tax Consulting. Highly recommend! Thank you, Emma.

Emma is brilliant! She offers a super clear and straightforward service, breaking through HMRC's infinite layers of bureaucracy and making your life just a bit easier.
And you know from the outset how much the service will cost so no surprises there.
She is quick to reply and is super friendly.
I can't recommend GTC enough!

As expats, we began our journey from the US to the UK in early 2020. Unbeknownst to us, our lack of research and settling on the nearest tax preparer that answered in the affirmative in being able to support our situation would be a costly mistake.
Enter GTC, at the suggestion of a UK-based global traveler that we also call a dear friend, who not only were able to onboard us to help with our returns going forward, but also review our previously submitted returns, finding accounting errors throughout. These errors proved to be in our benefit, and when extensive processing delays were encountered in our HMRC dealings, their doggedness was much appreciated. Highly recommend!

The service offered by GTC and Emma has been outstanding. She’s very knowledgeable about taxes and explain everything in details.
She has been extremely helpful with sorting out my taxes, as well as with advising about what I needed to do while moving out of the UK. Further, the platform she uses to provide documentation is one of the few decent platforms that I actually enjoy using. Overall a highly recommended service

Emma was absolutely fantastic. She returned e-mails really quickly and the whole process was efficient and fast. Emma is infinitely knowledgeable about all aspects of expat taxes - (we're husband and wife - he's from the US and she's from the UK but also has a US passport), and Emma explained every nuance clearly and as many times as we needed to understand it! Her understanding of ALL the tax codes and intricacies saved us a lot of money. We do our own taxes with Turbo Tax in the US and thought we had a good idea of how we'd do our UK taxes. That was not the case - it's much less intuitive, and Emma was absolutely fantastic! Couldn't recommend her more highly.

First time using the services and I have been very pleased from the start. Emma is highly knowledgeable, and she made my complicated tax affairs between UK and France very easy to manage. She responds very quickly to emails. I also found the portal set-up very handy, as it's all on one platform. I will definitely be using Global Tax Consulting again!

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.
I am genuinely pleased with Emma’s services and wholeheartedly recommend her and Global Tax Consulting. If you’re facing tax-related challenges, look no further!

I had a great experience with Emma and Global Tax Consulting. I have transitioned to freelance consultancy work as a digital nomad, as a British person working overseas. I received the expert advice I needed on my residency and tax status. The service is good value for money, efficient and clear - highly recommended!

Emma was exceptional. For context, I am an expat in the UK reporting foreign income to the HMRC, and I was recommended her by my lawyers in Portugal. From the first consultation call, Emma was extremely professional, and it was obvious that she knew the specifics of my situation very well given her clientele constitutes of people with a similar background to mine. Beyond her ability to explain the different tax laws to me, she was very quick to respond to any questions I had during the submission process and helped me identify the relevant documents that I had to submit. Also, very reasonably priced, especially when compared to larger players in the market (I can't see them offering any more than Emma's service. Very easy 5/5 rating.

I enlisted Emma to prepare and submit my tax return for 2022 and 2023. She demonstrated exceptional expertise and professionalism. Despite my limited understanding of the UK tax system, Emma provided thorough explanations and promptly addressed my queries. I value her impressive turnaround time and plan to continue working with her in the future. I highly recommend her services.

We would highly recommend Emma - she was a huge help in dealing with a difficult tax situation. She was prompt and responsive throughout the process. We greatly appreciated her skill in explaining complex situations and discussing options with us, and her taking extra time to do so. Lastly, she went above and beyond the call of duty for us when I made an error. We definitely plan on working with Emma again.

The free tax consultation I received was better than all of the many paid ones I had from other companies before. I finally know where I stand and what I have to do. Highly recommend. My advisor in particular was Emma McDermott. Not only did she provide excellent advice but listened to me without patronizing or belittling me like a lot of the aforementioned other companies did.

I’m lucky I found Emma – she’s helped me get on top of my taxes and navigate a disclosure.
She really knows her figures – even the HMRC even bowed to her knowledge and told us she was right and they were wrong.
I love that Emma’s happy to see things through until they’re finished, long after her initial payment.
My wife will need an accountant soon, and we’ll use Emma again.
