Our Approach

Based in the heart of London, Frontier Group is proud to offer to our clients a very personal and dedicated tax compliance and advisory service to individuals with the core objective of delivering tax efficiency and wealth protection

We understand that individuals may find dealing with their tax affairs to be a time consuming and often stressful process, which can be further complicated where their affairs involve expatriate matters such as holding offshore investments, relocating to the UK, or moving overseas. We are here to help ease that burden and guide you through the process of handling your tax and financial affairs in a cross border, international environment. We can offer a wealth of experience and expertise to ensure that your affairs are dealt with accurately, proactively and are structured in a compliant and tax efficient manner.

Frontier offers a proactive, efficient and comprehensive tax service to individuals. This we like to call our Membership service.
