Services
Living abroad does not necessarily remove your responsibility to submit a UK tax return. We help expatriates and non-residents report UK property income, pensions, employment earnings and other relevant income correctly. Our work includes completing the required residence pages, identifying applicable allowances and reclaiming eligible PAYE deductions. Through secure online document handling, professional preparation and direct HMRC submission, we make managing your UK tax affairs more straightforward.
We help individuals living internationally understand whether they qualify as UK resident or non-UK resident for tax purposes. Each assessment considers travel dates, UK working days, family connections, accommodation and other relevant ties. We apply the statutory tests to your circumstances, examine whether the tax year can be divided under split-year treatment, and deliver a written conclusion with supporting reasoning for your records or relevant third parties.
We help individuals plan international moves with their UK tax position firmly in mind. Whether you intend to leave the UK or establish residence here, our advice addresses residency rules, split-year treatment and the treatment of overseas income and gains. We coordinate the relevant planning decisions with your filing obligations, ensuring that claims, elections and self-assessment returns are prepared accurately and submitted in accordance with HMRC requirements.
We help landlords resolve undeclared UK rental income through HMRC’s Let Property Campaign, providing a structured route towards full tax compliance. By coming forward voluntarily, you may qualify for penalties at the lower end of the applicable range. We manage the entire disclosure process, from reconstructing rental accounts and calculating liabilities to submitting the necessary information and arranging payment.
Our Worldwide Disclosure Facility service offers a structured way to address undeclared offshore tax liabilities and bring your UK tax affairs up to date. We begin by examining your accounts, assets and financial records to determine the scope of the disclosure. Following registration with HMRC, we prepare the calculations, document the relevant behaviour and submit a complete disclosure and settlement offer within the required ninety-day period.
We take responsibility for the key stages of reporting Capital Gains Tax on UK property sales by non-residents. Our work begins with reviewing your completion statement, purchase costs, improvement expenditure and relevant valuation information. We then calculate the gain using each permitted basis, apply eligible reliefs and allowances, and choose the option that minimises the tax payable. The completed return is submitted to HMRC within 60 days, with payment details and copies supplied for your records.

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.

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

We could not possibly have navigated the UK tax system without Emma's help. My mum, now living in the US, had a tax issue that neither my sister nor I could help her with. Finding Global Tax Consulting online was a godsend. Emma was so knowledgeable, and quick to respond to every one of our numerous emails. She had it sorted and paid in a very short amount of time. Global Tax Consulting is worth every penny of their fee.

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.

We highly recommend Emma at Global Tax Consulting.
She recently helped us resolve a complicated, time-sensitive issue with our tax return. Emma's professionalism and technical expertise were immediately apparent; she swiftly identified the necessary corrective steps and resolved the matter efficiently.
It’s reassuring to know that when unexpected issues arise, we can count on GTC to help us. Emma was very professional and we are really pleased with her support.

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.

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!

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

I'm so glad that I went to Emma to file my return with HMRC. She was helpful, efficient and fast. I have waited weeks for international tax advisors to prepare my taxes - Emma did the job in 48 hours. I shall certainly be using Emma's services in the future.

I worked with Emma McDermott at GTC to file my UK taxes and resolve a complex tax situation that previous accountants had struggled with. Emma and the team at GTC were responsive, efficient, and communicative throughout the process. I would highly recommend their services to any expat in need of tax assistance abroad.

Emma helped us sort our first return to UK tax returns with our links to Canada and France and we were very happy with the quick responses we received and the action that was taken. We will be using her again & would definitely recommend.

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!

Really glad I found Emma and GTC to assist with filing a SA as a US expat. I have been using BrightTax for several years (to do an IRS return) and asked for a referral for a similar level of service for the HMRC return. I have been doing the accounting and filing myself and just don’t feel competent or confident. Emma and GTC sorted it out, filed the new SA and reviewed the previous year’s documents in the space of a week. So pleased. It has been a huge stressor because the implications of getting it wrong loom large. I hope to be able to refer my kids to both tax prep companies as they start working after college.

Emma has been an invaluable asset in understanding and managing my tax affairs both in the UK and abroad. Her professionalism is unmatched, consistently demonstrating a quick response time to my queries and providing clear, concise advice. Her expertise and dedication have been instrumental in resolving my tax issues, making a potentially stressful process much smoother. I'm very pleased with the service provided and would recommend her to those looking for reliable tax consulting services.

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.

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.

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.

I had the pleasure of working with Emma for my tax needs, and I couldn't be more satisfied with her services. Emma's extensive knowledge in tax matters was evident throughout the process. She displayed excellent attention to detail and ensured that every aspect of my taxes was thoroughly examined.

What stood out most was Emma's proactive approach. She asked all the right questions, leaving no room for oversight. Her follow-up was impeccable, and I felt reassured that my financial matters were in capable hands. I highly recommend Emma for anyone seeking a tax agent who is not only knowledgeable but also dedicated to providing top-notch service.

I would absolutely recommend GTC to anyone looking for tax support. I'm a dual resident with complicated international taxes and working with Emma has completely put my mind at ease. She knows her stuff and she's extremely reliable. Emma is also just a great person with a good energy, she's made doing my taxes somewhat enjoyable for a change!

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.

Emma is my accountant for NHS pensions matters. It is a niche area and finding accountants with such expert knowledge as Emma is next to impossible. She has always been a pleasure to deal with and always responds promptly to any matters arising. I would highly recommend her for NHS pensions tax calculations and scheme pays elections.
