Services
We specialise in preparing UK Self Assessment tax returns for expatriates, non-residents and international clients. Our service covers the relevant residence, employment, property and foreign income pages, ensuring your tax position is accurately reported. We identify applicable allowances, refunds and treaty relief, then prepare and submit your return to HMRC within the required deadline.
We help expatriates establish their UK tax residency status through a detailed review of the Statutory Residence Test. Your assessment covers UK presence, employment abroad or in the UK, available accommodation and relevant family and other connections. We apply the appropriate HMRC tests, consider whether split-year provisions are available and provide a written explanation of the resulting position for reference when dealing with employers, banks or HMRC.
At Global Tax Consulting, we advise internationally mobile individuals on establishing and maintaining the correct UK tax position. Our work includes planning departure and arrival dates, assessing eligibility for residence-based reliefs, and arranging asset disposals in accordance with applicable tax rules. We consider foreign income, capital gains and potential double taxation, while accounting for temporary non-residence provisions. Our support extends to preparing returns and submitting the required documentation to HMRC.
Our Let Property Campaign service provides comprehensive assistance to landlords who need to bring their UK rental income tax affairs up to date. We reconstruct rental accounts using available records, identify relevant expenses, and calculate the liabilities for each year concerned. From notifying HMRC and submitting your disclosure within the required 90-day period to addressing penalties and payment arrangements, we manage the process with a focus on compliance.
Our Worldwide Disclosure Facility service helps you bring your UK tax affairs up to date when foreign income, gains or assets have not been declared. We assess the relevant accounts, assets and tax years before handling registration through HMRC’s Digital Disclosure Service. Our team calculates the amounts due, considers applicable foreign tax credits and treaty relief, and prepares the disclosure and settlement offer, including negotiating payment arrangements where necessary.
We help overseas property sellers fulfil their UK capital gains tax responsibilities with a thorough, deadline-focused service. Following completion, we review the purchase details, valuation information and eligible costs before calculating the gain on all three permitted bases. We select the lowest-tax option, consider any available reliefs and allowances, and handle the HMRC return and associated payment details to support accurate reporting within 60 days of completion.

I can’t say enough good things about Emma. From day one, she has given me complete 360-degree support through my tax situation. She’s proactive, incredibly responsive, and stays ahead of every deadline.
What I appreciate most is her communication style. She’s so down-to-earth and translates complex financial language into terms I can actually understand. She makes taxes stress-free and easy to navigate. Thank you so much for everything, Emma! Looking forward to working together moving forward!

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 have used the services of Global Tax Consulting for help with UK tax returns as someone who no longer resides in the UK. I must say that the quality of the service was just excellent. From the professionalism, the speed and the guidance, everything was very well handled and explained. I am certainly a very satisfied client who would most likely return if needed. Thank you Emma for all your great work.

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 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.

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!

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’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.
