At Quastels we are known for providing guidance that is technically robust and client-focused. Our tax specialists navigate complexity with confidence.

Remittance Basis of Taxation and the Foreign Income and Gains (FIG) Regime

For international clients, understanding the remittance basis of taxation and the new FIG regime is key to optimising our clients’ UK tax position. Our lawyers provide expert guidance to ensure that non-UK income and gains are structured correctly, allowing clients to retain financial control while minimising UK tax exposure.

International Estate Planning

Effective estate planning is crucial for high-net-worth families. We provide bespoke strategies to manage succession across multiple jurisdictions, taking into account different tax laws. Our expertise allows us to create a coherent plan that protects global wealth for future generations.

Non-UK Trusts

Establishing non-UK trusts can provide significant tax benefits for international clients. We offer comprehensive advice on setting up and administering non-UK trusts, ensuring that these structures align with both personal and family goals while optimising tax efficiency.

Double Taxation Treaties

Navigating double taxation treaties is vital for high-net-worth individuals with assets and income in multiple jurisdictions. Our international tax lawyers provide expert advice on how to benefit from these treaties, ensuring that tax positions are optimised globally while avoiding unnecessary liabilities.

Pre-Arrival and Exit Planning

Whether planning to move to the UK or leave, managing the tax implications is essential. Our international tax lawyers provide pre-arrival and exit planning services to ensure any transition is smooth and tax-efficient, aligning personal and business interests with ultimate financial goals.

Tax Disputes & Investigations

Tax disputes can be complex and disruptive, requiring careful management and expert advocacy. Our experienced tax solicitors represent clients in disputes with HMRC, ensuring that rights are protected and matters are resolved efficiently. We handle investigations with discretion, striving to secure the best possible outcomes for our clients.

Corporate & Personal Tax Integration

For many high-net-worth individuals, personal and corporate tax affairs are intricately linked. Our team creates integrated tax strategies to ensure that business success translates into personal wealth efficiently and provides protection for the future.
