Services
Residency Planning
We analyze your circumstances under the Statutory Residence Test (SRT) to determine residency status. Our expertise ensures accurate split-year treatment or non-resident claims, minimizing UK tax exposure while maintaining HMRC compliance. Ideal for expats and remote workers.
Tax Returns
We prepare and submit UK tax returns for residents and non-residents, including foreign income, split-year claims, and property disclosures. Our process ensures timely filing and maximizes reliefs like the FIG scheme or foreign tax credits.
Employer Compliance
We advise businesses on HMRC obligations for employees working abroad, covering PAYE, NIC, and employer reporting. Our guidance ensures compliance while supporting flexible work arrangements for globally mobile teams.
Property Capital Gains
We calculate and report Capital Gains Tax on UK property disposals, filing returns within HMRC's 60-day deadline. Our strategies mitigate tax liabilities and structure future sales for optimal outcomes.
Voluntary Disclosure
We prepare voluntary disclosures using HMRC's Worldwide Disclosure Facility or Let Property Campaign to report undeclared income. Our approach reduces penalties and ensures compliance for clients with historical tax obligations.
Questions
Do I need to file a UK tax return if I live abroad?
Yes, if you have UK income, pensions, or property. We prepare returns for non-residents to ensure HMRC compliance.
What is the Statutory Residence Test (SRT)?
The SRT determines UK tax residency based on days in the UK, family ties, and work connections. We help assess your status.
What is split-year treatment?
Split-year treatment divides a tax year into resident and non-resident periods. We help qualify clients leaving or arriving mid-year.
What is the FIG scheme?
The FIG scheme exempts foreign income for up to four years. We advise eligibility and file claims with HMRC.
How do I notify HMRC when leaving the UK?
We handle Form P85 or SA109 filings to document your departure and non-resident claims smoothly.
Do I owe CGT on UK property sold abroad?
Yes. We prepare and submit CGT returns within HMRC's 60-day deadline to ensure compliance.

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

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.

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

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.

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.

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!
