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 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.
Our international tax advisory service helps individuals manage the UK tax implications of relocating abroad or arriving in the country. We assess your residence position, review relevant income and assets, and identify applicable reliefs before determining the appropriate approach. From departure dates and asset disposals to treaty claims and annual filings, we provide practical support designed to establish the correct tax position and meet HMRC requirements.
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.
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.
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!

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.

I contacted GTC for a tax residency assessment and was really impressed with the service I received. Emma was fantastic to deal with – responsive, knowledgeable, and quick to answer any questions I had.

The whole process was straightforward, with a very fast turnaround and clear advice throughout. I'd happily recommend GTC to anyone looking for tax residency or international tax guidance and would definitely use their services again.

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 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.

I’m really grateful to Emma and the team at Global Tax Consulting for helping me with my non-resident UK tax situation. It was quite stressful and confusing at first, but Emma explained everything clearly and guided me through the whole process.
The amended tax return was handled smoothly and the communication throughout was excellent. I really appreciated how supportive and professional the team was.

I would definitely recommend them to anyone needing help with non-resident UK tax matters.

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 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.

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 was a digital nomad this year and had decided I wanted to leave the UK and become a non-tax resident, I was overwhelmed with all the requirements and didn't fully understand it all. After working with Emma I now have list of requirements I need to meet based on my personal situation which I fully understand. She also helped with my P85 to get a NT (non tax) code which HMRC approved. Would happily work with again.

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.
