Tax & Advanced Planning

We don’t just address the challenges of Tax and Advanced Planning, we help you turn them into opportunities.


Navigating the complexities of tax and advanced planning

Effective tax planning and advanced wealth structuring are critical components of preserving and growing your wealth. Our approach is rooted in providing you with the tools and strategies to optimise your financial situation, especially considering the unique challenges that international Americans face due to FATCA (Foreign Account Tax Compliance Act).

Our Tax and Advanced Planning team consists of three dual qualified US/UK tax advisers, Tahir Mahmood, Ed Johnson and Laima Zirne. Having worked in practice for “big 4” firms and boutique tax practices, they bring a wealth of knowledge to our clients.



PLEASE NOTE: We do not provide tax advice, we collaborate with you and your London & Capital Adviser to structure your wealth in the most tax-efficient way possible.

What to expect as a client

At London & Capital, our approach to wealth management is distinctly planning-led. We go beyond conventional financial strategies by taking a comprehensive view of your entire wealth, life and family dynamics. Your dedicated Adviser will work with a member of the tax team and together you will consider every aspect of your financial landscape, acknowledging the interconnectedness of your personal and professional aspirations.

When crafting a financial plan for your future, we assess your entire wealth portfolio, irrespective of whether it resides with London & Capital or elsewhere. And our commitment extends globally, recognising the international nature of our clients’ financial interests. By prioritising a holistic understanding of your circumstances, we ensure that our financial planning services align seamlessly with your goals, providing you with a roadmap for a secure and prosperous future.

US citizens and green card holders

International Americans, including US citizens living abroad, often encounter intricate tax regulations and reporting requirements. FATCA, in particular, has increased the scrutiny on financial accounts held by US taxpayers outside of the United States. Non-compliance can result in significant penalties, making it crucial to have a strategic approach.

We are expert in managing the complexities of wealth management for US taxpayers residing in the UK and overseas:

Tax Compliant Investments

The use of tax-compliant investments and avoiding punitively taxed ones such as Passive Foreign Investment Companies (PFICs) and HMRC non-reporting funds.

Bespoke asset allocation

A focus on portfolio construction and a bespoke asset allocation which maximises net of US/UK tax returns.

Reducing tax burden

Consideration given to the FATCA reporting requirements of being a US taxpayer living overseas and reducing this burden for you where possible.

Non-domiciled Individuals

  • Providing guidance and to help you plan for opportunities in the structuring of your assets, which can occur due to a planned move to or from the UK.
