ABOUT ME

Boutique advice for international tax matters

Navigating international tax can be complex, the right advice shouldn't be.
Nicholls Tax Advisory was founded to provide the kind of personal, technically excellent service that businesses, internationally mobile individuals and families often struggle to find with larger firms.
My clients can expect direct access to an experienced adviser who understands both the technical detail and the practical realities of living and working across borders.

MY STORY

Experience that
makes a difference.

Professional standards
Nicholls Tax Advisory is registered with the Association of Taxation Technicians for the purposes of Anti - Money Laundering legislation. This reflects my commitment to maintaining appropriate professional and regulatory standards.
Nicholls Tax Advisory is led by Sadie Nicholls, a tax specialist with two decades of experience and a strong focus on international tax for individuals, families and businesses.
As a qualified member of the Association of Taxation Technicians (ATT), Sadie brings extensive hands-on experience advising clients across multiple jurisdictions, having built her technical advisory expertise through years of complex, cross border case work.
Sadie believes the best advice starts with understanding the people behind the numbers - whether you're planning retirement with pensions held overseas, part of a globally mobile workforce sending or receiving employees across borders, or navigating a move to or from the UK, whatever the reason the focus is straight forward: that double taxation is avoided or reclaimed under the relevant tax treaty, your reporting obligations are met on both sides and that the timing of your move is planned to be as efficient as possible
After two decades within a leading professional services firm, Nicholls Tax Advisory was established with a simple aim:
To provide exceptional technical advice with the personal service that only an independent boutique practice can offer.

MY PHILOSOPHY

Good advice
should be:

Easy to
understand
Complex rules explained in plain English, so you understand the reasoning behind the advice, not just the advice itself.
Technically
robust
Grounded in a deep understanding of current tax legislation, and how HMRC applies it in practice, not just textbook rules.
Commercially
practical
Advice you can actually act on, weighed against what's realistic for your circumstances, not just what's theoretically optimal.
Delivered
personally
Every engagement is led personally by Sadie, from first conversation through to implementation.
Focused on long-term relationships
Built to support you through the next chapter too; a move, a sale, a new job overseas, not just the issue in front of you today.
My role isn't simply to explain legislation - it's to help clients make informed decisions with confidence.
