Our Tailored UK Tax Advice for Non-Residents

International tax is arguably the most complex area of taxation, where multiple legal systems intersect and small details can have significant consequences. The rapid pace of global tax reform, including initiatives like BEPS and increased information exchange between countries, means staying compliant requires specialist knowledge. 


Our international tax advisors understand not just the technical rules, but also the practical realities of living and doing business across borders. We’ve helped clients navigate everything from simple residency changes to complex multinational restructuring, always with an eye on both immediate compliance needs and long-term strategic objectives.

Frequently Asked Questions.

Here is a list of the most frequently asked questions from our clients.

Q.

How can international tax treaties help reduce my tax burden?

A.

Double taxation relief in the UK can provide significant benefits including reduced withholding tax rates, exemptions from certain taxes and tie-breaker rules for determining tax residency. However, accessing these benefits often requires meeting specific conditions and following correct procedures, and anti-treaty shopping rules mean the benefits aren’t always available even when a treaty exists between relevant countries!

Q.

What are the key considerations when setting up a business in the UAE or other GCC countries?

A.

The GCC region offers attractive business environments, but you need to consider corporate tax rates, VAT obligations, substance requirements and how the structure interacts with your home country tax position. For example, changes to corporate tax in the UAE mean that structures that worked previously may need review, making current professional advice crucial.

Q.

How do I know if I’ll be considered as a tax resident when moving between countries?

A.

Tax residency rules vary significantly between countries and often depend on factors like days spent in each territory, accommodation arrangements and family ties. Each country has its own test so it is possible to be a tax resident of more than one country at the same time. It’s important to get professional tax advice before making any international move to avoid paying too much or too little tax to the wrong country!

My wife and i booked a consultation with Omar at Aswatax recently. He provided exceptional advice on property incorporation, offering insights that even our accountant hadn’t considered his recommendations were awesome and we are now implementing them. I highly recommend him to anyone seeking expert guidance on property incorporation or tax matters. Thank you, Omar!

I first spoke to Omar over a year ago where we spoke about a Group structure and its benefits. Omar answered my questions, was patient and wasn’t pushy. I knew he was at the end of the phone when and if I received to go down that route.

Eventually when we were ready to move forward with a Group structure Omar made everything simple to understand and the process has been a great experience.
