Services
We provide comprehensive UK Self Assessment assistance to clients whose tax affairs extend beyond the UK. Whether you live overseas, have recently arrived in Britain or receive rental income from UK property, we determine which reporting requirements apply to your circumstances. Our service includes preparing residence and foreign income pages, applying available reliefs, addressing previous outstanding returns and submitting the completed documentation to HMRC through a carefully managed process.
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.
Our approach to international tax advice begins with understanding your circumstances, intended relocation and financial arrangements. We then consider residence status, applicable tax treaties, the timing of disposals and the reliefs available to you. For individuals departing the UK, we help assess non-resident status and relevant departure-year provisions; for new arrivals, we examine potential foreign income and gains relief and double tax mitigation, alongside the associated reporting responsibilities.
Through our Let Property Campaign support, we help resident and non-resident landlords correct omissions in their UK rental income reporting. We establish the relevant tax years, rebuild financial records where documentation is incomplete and calculate the outstanding tax, interest and penalties. By preparing the figures and supporting evidence before notifying HMRC, we organise the disclosure process efficiently and help secure a suitable settlement while establishing arrangements for continued compliance.
We guide clients through the process of correcting undeclared offshore tax matters, providing assistance from the initial assessment through to final settlement with HMRC. Our approach includes reviewing overseas income, investment gains and financial accounts, determining the relevant disclosure period and calculating the tax, interest and potential penalties. We also assess available reliefs and present the circumstances of the omission accurately to support a properly prepared Worldwide Disclosure Facility submission.
Our non-resident Capital Gains Tax service is designed for individuals disposing of UK residential property while living overseas. We calculate the gain under each applicable method and identify the option that produces the lowest tax liability. Where appropriate, we also consider private residence relief, acquisition expenses, improvement costs, selling fees and capital losses. We then prepare the HMRC return, meet the 60-day deadline and provide confirmation for your records.

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 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 was really thorough and did a great job on our UK tax return, which is complicated as I’m also a US citizen. She managed to get us a substantial return from overpayment when I did my taxes alone using tax software.

Received quick and expert advice regarding my tax situation, as well as a filled out tax return. I overpaid taxes for my non-resident period of the year, and Emma at GTC helped me get it back. The price is more than fair.

I'm a digital nomad from the UK and worked with GTC to help with my tax return and non-residency status. Super responsive professional team, my advisor Emma was able to answer all my queries and hold my hand throughout the process. Would recommend to any digital nomads!

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.

GTC and Emma are exceptional. Incredibly knowledgeable and experts in the field. Their client service and responsiveness are off-the-charts fantastic.

Some context - having been relocated for work, I was a Swiss expat for several years before returning home to the UK, resulting in fairly complex international tax and expat-tax matters. I can unequivocally and honestly say that I do not know where I’d be without Emma’s guidance and assistance. To say she removed a huge chunk of my stress is an understatement.

Emma is professional, extremely efficient, responsive and has the ability to patiently guide one through the myriad of tax issues and nuances with the utmost care, detail and consideration. She does this while ensuring that the outcomes are optimal and fully compliant.

I have taken complex international tax matters to Emma and she has not only guided me through the UK requirements, but also my advisors and colleagues in Switzerland, sometimes taking the time to speak to them directly to assist their understanding.

I wholeheartedly (and highly!) recommend Emma and GTC to anyone needing UK tax assistance or advice.

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 recently had the pleasure of working with Emma at Global Tax Consulting, and I must say she is truly amazing. From the moment I reached out to her for assistance, Emma exhibited a high level of expertise and professionalism.

Emma took the time to thoroughly understand my situation, addressing all my concerns with clarity and precision. What sets Emma apart from the other tax consultants I have worked with is her extremely friendly and personable approach and her communication. She made me feel at ease from the start and explained things in a way that was easy for me to understand and ensured that I was well-informed throughout the entire process.

Working with Emma has been a game-changer for me, and I genuinely wish I had found her sooner. I highly recommend Emma and Global Tax Consulting to anyone in need of expert guidance and a seamless tax consulting experience.

Excellent, responsive work from Emma. UK tax for non resident personnel resulted in a refund less than a week after Emma submitted my self-assessment form. She has also helped provide the correct tax position for my Double Taxation problems within Spain. I couldn't recommend GTC more highly.

I contacted Global Tax Consulting for an assessment of my international tax situation and got very useful and competent advice. They provided a written memo followed by a video call where they clarified any outstanding doubt. They have been very responsive and helpful throughout the process and definitely recommend them for anyone who's looking for advice on international tax issues.

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 am very satisfied with the excellent service provided by Emma. She not only effectively resolved my expat tax issues but also demonstrated a strong commitment to her clients. Emma's timely responses to my emails and her deep understanding of international tax regulations greatly facilitated a complex process. Her dedication to optimizing my tax situation while ensuring full compliance was truly impressive. I am sincerely grateful for her professionalism and wholeheartedly recommend her to anyone seeking expert assistance with international tax matters. I am genuinely pleased with the service she provided.

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.

Cross-border taxes can be quite complicated to deal with, so I am glad I found Global Tax Consulting. Emma helped prepare my tax returns, providing valuable help in helping me make sense of the various tax rules applicable to my specific circumstances. I really appreciated the prompt service, transparent and upfront pricing, as well as the willingness to discuss my specific complexities in more detail as needed. 100% would recommend using GTC for your tax returns.

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.
