R MON

We, as a family, decided to move overseas. Emma from Global Tax Consulting went above and beyond, providing clear and precise advice and assisting us with completing all the necessary forms. I would highly recommend her services.

Great service and support!

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.

Emma is brilliant

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!

Excellent service

Emma was fantastic. Efficient, helpful and fast. International tax advisors have taken weeks to prepare my return. Emma did the job in 48 hours. I'm really grateful I found her!

Finally peace of mind as a digital nomad!

Emma has been incredibly helpful and polite throughout the entire process. She was responsive from the very first email and supported me on my journey as a freelance digital nomad. I now have peace of mind knowing I can manage my taxes while travelling across multiple countries and have clarity on my tax residency questions."

Amazing service

The service offered by GTC and Emma has been outstanding. After our initial call she made me aware about the fact that I could claim back my taxes as a non-resident and she took her of that from start to finish, all I needed to do was to provide all the necessary documentation through their platform, which is also very easy to use. Definitely a recommended service, which I will 100% use in the future.

Exceptional UK Tax and Residency Planning Services

I highly recommend GTC for anyone dealing with complex UK tax and residency issues, especially those involving multiple countries. Emma, who handled my case, was outstanding in every aspect. The peace of mind that GTC's services brought me was invaluable.

In my situation, they expertly navigated the intricacies of tax matters between Spain and the UK. Emma's approach was incredibly efficient, speedy, and detailed. She explained the complexities of my situation, including the double taxation agreement between the two countries, in a way that was easy to understand. Her expertise and attention to detail were evident throughout the process.

What truly set the experience apart was Emma's willingness to go above and beyond. She exceeded my expectations at every turn, demonstrating exceptional dedication and professionalism.

If you're facing any tax affairs issues, particularly those involving international elements, I wholeheartedly recommend GTC. Their expertise and commitment to client satisfaction make them an invaluable partner in navigating the complex world of international taxation.

Speedily helped with a complex UK-US tax issue with HMRC.

I have a complicated UK-US tax situation and needed help untangling some prior errors in my HMRC filings asap. Having dealt with things myself originally (and pretty much correctly, as it turned out), I then had two *terrible* experiences with two sets of UK-based accountants, both of whom swore that they understood how the UK-US tax treaty worked (they didn't) and strongly implied I was an idiot for how I had done things (actually, I'd been in the right). I really fear for their other customers, if they've all been given the same incorrect advice! Unfortunately, I didn't realize how bad their advice was until *after* I'd paid one of them to help me re-file my taxes with HMRC :(
Fortunately, I finally found Emma and GTC, who confirmed my original understanding (and was patient and sympathetic as I then had a near-meltdown over zoom), and then went FAR beyond that in advising me of what to do next and how to re-(re-!)file. Not only did Emma patiently explain the entire situation and what steps I needed to take, she speedily produced my new tax filing documents (including a deduction I wouldn't have known about), and was always extremely fast to respond to inputs I provided or to my (usual) multitude of questions. She also helped me to appeal against more penalties and kept me updated on that process, which appears to have been successful at this stage. Emma has consistently gone above and beyond for me - I'm extremely grateful, and I would not hesitate to recommend her!
